Benefits of a dance group intervention on institutionalized elder people: A Bayesian network approach
2018
[EN] The present study aims to explore the effects of an adapted classical dance intervention on the psychological and functional status of institutionalized elder people using a Bayesian network. All participants were assessed at baseline and after the 9 weeks period of the intervention. Measures included balance and gait, psychological well-being, depression, and emotional distress. According to the Bayesian network obtained, the dance intervention increased the likelihood of presenting better psychological well-being, balance, and gait. Besides, it also decreased the probabilities of presenting emotional distress and depression. These findings demonstrate that dancing has functional and …
Study of the leisure influence on attitude for leisure and mental health in a sample of portuguese seniors
2017
Increased human longevity has been attributed to technological and medical advances, as well as improved hygiene and nutritional conditions, access to health care, changes in eating habits and cognitive development strategies (Osório, 2007). The present study examined the influence of leisure actions in the psychological well-being, leisure attitude and distress of seniors. The sample consisted of 403 participants (37,2% male; 62,8% female). Concerning the perception of health condition, 82,6% subjects were considered independent and 17,4% participants were considered dependent. The instruments used were the MHI (Ribeiro, 2001) and the LAS (Freire & Fonte, 2007). Main results exposed that p…
Global Cognitive Functioning versus Controlled Functioning throughout the Stages of Development
2020
According to the All or None Hypothesis (Diamond, 2009), the cognitive system can operate in a global manner that is not very discriminate or in a more discriminate mode that demands greater precision, control, and cognitive effort. There are five corollaries to this hypothesis that describe, in an operative way, the conditions under which the controlled mode of functioning in the cognitive domain can be activated and thus tested. Given the impact this theory has generated and the absence of studies analyzing the corollaries in a collective and systematic way at different stages of development, this study was proposed, first of all, to test three of these corollaries in children, adolescent…
Monte Carlo Simulation of a Modified Chi Distribution with Unequal Variances in the Generating Gaussians. A Discrete Methodology to Study Collective …
2020
The Chi distribution is a continuous probability distribution of a random variable obtained from the positive square root of the sum of k squared variables, each coming from a standard Normal distribution (mean = 0 and variance = 1). The variable k indicates the degrees of freedom. The usual expression for the Chi distribution can be generalised to include a parameter which is the variance (which can take any value) of the generating Gaussians. For instance, for k = 3, we have the case of the Maxwell-Boltzmann (MB) distribution of the particle velocities in the Ideal Gas model of Physics. In this work, we analyse the case of unequal variances in the generating Gaussians whose distribution w…

Mathematical Modeling for Neuropathic Pain: Bayesian Linear Regression and Self-Organizing Maps Applied to Carpal Tunnel Syndrome
2020
A better understanding of the connection between risk factors associated with pain and function may assist therapists in optimizing therapeutic programs. This study applied mathematical modeling to analyze the relationship of psychological, psychophysical, and motor variables with pain, function, and symptom severity using Bayesian linear regressions (BLR) and self-organizing maps (SOMs) in carpal tunnel syndrome (CTS). The novelty of this work was a transfer of the symmetry mathematical background to a neuropathic pain condition, whose symptoms can be either unilateral or bilateral. Duration of symptoms, pain intensity, function, symptom severity, depressive levels, pinch tip grip force, a…
Spectral Clustering Reveals Different Profiles of Central Sensitization in Women with Carpal Tunnel Syndrome
2021
Identification of subgroups of patients with chronic pain provides meaningful insights into the characteristics of a specific population, helping to identify individuals at risk of chronification and to determine appropriate therapeutic strategies. This paper proposes the use of spectral clustering (SC) to distinguish subgroups (clusters) of individuals with carpal tunnel syndrome (CTS), making use of the obtained patient profiling to argue about potential management implications. SC is a powerful algorithm that builds a similarity graph among the data points (the patients), and tries to find the subsets of points that are strongly connected among themselves, but weakly connected to others.…
Happiness in advanced adulthood and the elderly
2016
The purpose of this study was to critically analyse the role that positive emotions, flourishing and mindfulness have among the elderly. It was explored how these concepts can contribute to successful aging and higher levels of happiness in this population. To this end, we conducted a non-experimental correlational study with 329 participants, aged from 55 to 98 years. Questionnaires were used to collect data through the following instruments: a socio-demographic questionnaire, Mindful Attention Awareness Scale (MAAS), Satisfaction With Life Scale (SWLS) and PANAS (Positive and Negative Affect Schedule), FS (Flourishing scale), PST (Positivity test), MHI-5 (Mental Health Inventory -- 5).

Serious Games for Elderly Continuous Monitoring
2014
Information technology (IT) and serious games allow older population to remain independent for longer. Hence, when designing technology for this population, developmental changes, such as attention and/or perception, should be considered. For instance, a crucial developmental change has been related to cognitive speed in terms of reaction time (RT). However, this variable presents a skewed distribution that difficult data analysis. An alternative strategy is to characterize the data to an ex-Gaussian function. Furthermore, this procedure provides different parameters that have been related to underlying cognitive processes in the literature. Another issue to be considered is the optimal dat…

Sleep disturbances in tension-type headache and migraine
2017
Current research into the pathogenesis of tension-type headache (TTH) and migraine is focused on altered nociceptive pain processing. Among the potential factors that influence sensitization mechanisms, emotional stress, depression, or sleep disorders all have an essential role: they increase the excitability of nociceptive firing and trigger hyperalgesic responses. Sleep disturbances and headache disorders share common brain structures and pathogenic mechanisms and TTH, migraine, and sleep disturbances often occur together; for example, 50% of individuals who have either TTH or migraine have insomnia. Moreover, insomnia and poor sleep quality have been associated with a higher frequency an…
Corrigendum: ExGUtils: A Python Package for Statistical Analysis With the ex-Gaussian Probability Density
2018
The study of reaction times and their underlying cognitive processes is an important field in Psychology. Reaction times are usually modeled through the ex-Gaussian distribution, because it provides a good fit to multiple empirical data. The complexity of this distribution makes the use of computational tools an essential element in the field. Therefore, there is a strong need for efficient and versatile computational tools for the research in this area. In this manuscript we discuss some mathematical details of the ex-Gaussian distribution and apply the ExGUtils package, a set of functions and numerical tools, programmed for python, developed for numerical analysis of data involving the ex…
Machinery Failure Approach and Spectral Analysis to Study the Reaction Time Dynamics over Consecutive Visual Stimuli: An Entropy-Based Model.
2020
[EN] The reaction times of individuals over consecutive visual stimuli have been studied using an entropy-based model and a failure machinery approach. The used tools include the fast Fourier transform and a spectral entropy analysis. The results indicate that the reaction times produced by the independently responding individuals to visual stimuli appear to be correlated. The spectral analysis and the entropy of the spectrum yield that there are features of similarity in the response times of each participant and among them. Furthermore, the analysis of the mistakes made by the participants during the reaction time experiments concluded that they follow a behavior which is consistent with …

Patient Profiling Based on Spectral Clustering for an Enhanced Classification of Patients with Tension-Type Headache
2020
Profiling groups of patients in clusters can provide meaningful insights into the features of the population, thus helping to identify people at risk of chronification and the development of specific therapeutic strategies. Our aim was to determine if spectral clustering is able to distinguish subgroups (clusters) of tension-type headache (TTH) patients, identify the profile of each group, and argue about potential different therapeutic interventions. A total of 208 patients (n = 208) with TTH participated. Headache intensity, frequency, and duration were collected with a 4-week diary. Anxiety and depressive levels, headache-related burden, sleep quality, health-related quality of life, pre…

The effects of age and emotional valence on recognition memory: An ex-Gaussian components analysis
2014
[EN] The aim of this work was to study the effects of valence and age on visual image recognition memory. The International Affective Picture System (IAPS) battery was used, and response time data were analyzed using analysis of variance, as well as an ex-Gaussian fit method. Older participants were slower and more variable in their reaction times. Response times were longer for negative valence pictures, however this was statistically significant only for young participants. This suggests that negative emotional valence has a strong effect on recognition memory in young but not in old participants. The tau parameter, often related to attention in the literature, was smaller for young than …
Ageing: Not only an age-related issue.
2021
Developments in the last century have led to an unprecedented increase in life expectancy. These changes open opportunities for humans to grow and develop in healthy and adaptive ways, adding life to years as well as years to life. There are also challenges, however - as we live longer, a greater number of people will experience chronic illness and disability, often linked to lifestyle factors. The current paper advances an argument that there are fundamental biological sex differences which, sometimes directly and sometime mediated by lifestyle factors, underpin the marked differences in morbidity and mortality that we find between the sexes. Furthermore, we argue that it is necessary to c…

Community detection-based deep neural network architectures: A fully automated framework based on Likert-scale data
2020
[EN] Deep neural networks (DNNs) have emerged as a state-of-the-art tool in very different research fields due to its adaptive power to the decision space since they do not presuppose any linear relationship between data. Some of the main disadvantages of these trending models are that the choice of the network underlying architecture profoundly influences the performance of the model and that the architecture design requires prior knowledge of the field of study. The use of questionnaires is hugely extended in social/behavioral sciences. The main contribution of this work is to automate the process of a DNN architecture design by using an agglomerative hierarchical algorithm that mimics th…

Study of the perception of active workers in preparation for retirement
2016
In a reality where we assist aging population, it is important to create more strategies to make this stage of life more positive and healthy. We know that many losses occur in this process on social and individual levels. The retirement is one of these losses, this one with great impact on the elderly people, once they've been professionally active during a great part of their lives. Thus, emerges the interest on creating early strategies that able adult and active people to prepare their retirement process, to the transition from active work to retirement. We proposed a study that permit us to examine the impact that education for retirement (with, for example, courses) could have in how …

The objective of this study is to describe the relationships between grandchildren and their favourite grandparents, by studying the socialization styles used by latter and the shared activities undertaken. The participants were 360 children between 10 and 12 years old, who completed the grandparent-grandchild relationship questionnaire of Rico, Serra and Viguer (2001) and the socialization questionnaire of Rey and Ruiz (1990). The results demonstrate the importance of gender and family line in the selection of the favourite grandparent, differences being shown in the types of shared activities and in socialization styles. It is concluded that in the majority of cases the profile of the fav…
Prevalence of Cognitive Frailty, Do Psychosocial-Related Factors Matter?
2020
Cognitive frailty (CF) is a topic of growing interest with implications for the study of preventive interventions in aging. Nevertheless, little research has been done to assess the influence of psychosocial variables on the risk of CF. Our objectives were to estimate the prevalence of CF in a Spanish sample and to explore the influence of psychosocial variables in this prevalence. Physical frailty and cognitive, functional, psychosocial, and socio-demographic aspects were assessed in a sample of 285 participants over 60 years. Univariate and multivariate logistic regression models were carried out. A prevalence of 21.8% (95% CI 17.4&ndash

Resilience and the Aging Process: Assessment Tools and Needs
2015
Abstract Successful resilience is a variable often related to an optimal aging process and that might have a role on education. However, literature is rather limited when dealing with assessment instruments for the elderly in the Spanish language. The objective of this work is to examine the Brief Resilient Coping Scale (Sinclair &Wallston, 2004), a four item likert scale, in the Spanish elderly. This scale was administrated to a sample of 920 elderly Spanish participants, and the data set analysed in terms of exploratory and confirmatory factor analysis and internal consistency. The scale demonstrated good psychometric properties. Furthermore, the homogeneity indices were higher than in th…

Abstract: Mild cognitive impairment (MCI) is one of the most important clinical entities in the field of cognitive neuroscience, the size of their numbers and the possible evolution of some of the subtypes of dementia. The aim of this study is to test a method and procedure for classification of MCI in terms of neuropsychological test scores and its convergence with established clinical criteria, and analyze the differences between the resulting groups. After applying the inclusion-exclusion criteria, was as- sessed using a battery of neuropsychological tests to 39 people aged be- tween 60 and 89 years. Diagnostic groups…
Sex Hormones and Healthy Psychological Aging in Women
2018
Besides their key role in reproduction, estrogens have effects in several organs in the body, as confirmed by the identification of estrogen receptors (ER) in multiple tissues. Experimental evidence has shown that estrogens have significant impacts on the central nervous system (CNS), and a key question is to what extent the fall in estrogen levels in the blood that occurs with increasing age, particularly around and following the menopause, has an impact on the cognitive function and psychological health of women, specifically regarding mood. This review will consider direct effects of menopausal changes in estrogens on the brain, including cognitive function and mood. Secondary pathways w…
Differences Between Young and Old University Students on a Lexical Decision Task: Evidence Through an Ex-Gaussian Approach
2013
This work compared two common variants of a lexical decision task (LDT) through two different analysis procedures: first, the classical ANOVA method, and second, by fitting the data to an ex-Gaussian distribution function. Two groups of participants (old and young university students) had to perform, blocks of go/no-go and yes/no tasks. Reaction times and error rates were much lower in the go/no-go task than in the yes/no task. Changes in the ex-Gaussian parameter related to attention were found with word frequency but not with the type of LDT tasks. These findings suggest that word frequency shows an attentional cost that is independent of age.
Age slowing down in detection and visual discrimination under varying presentation times
2017
[EN] The reaction time has been described as a measure of perception, decision making, and other cognitive processes. The aim of this work is to examine agerelated changes in executive functions in terms of demand load under varying presentation times. Two tasks were employed where a signal detection and a discrimination task were performed by young and older university students. Furthermore, a characterization of the response time distribution by an exGaussian fit was carried out. The results indicated that the older participants were slower than the younger ones in signal detection and discrimination. Moreover, the differences between both processes for the older participants were higher,…
Frailty and multimorbidity: Two related yet different concepts.
2016
The extension of life expectancy is a global phenomenon. The growth in the ageing population has created a new health scenario in which there is a higher prevalence of frailty and multimorbidity. The attention received by both conditions derives from their strong association with disability, hospitalization, and death. The aim of the present paper is to conceptualize and differentiate these terms and to discuss their interrelations. We conclude that, yet related, they represent two different clinical conditions. Frailty identifies the increased vulnerability to stressors due to a dynamic, non-linear, and multidimensional depletion of physiological reserve and redundancy, whereas multimorbid…
Mild cognitive decline. A position statement of the Cognitive Decline Group of the European Innovation Partnership for Active and Healthy Ageing (EIP…
2016
Introduction: Mild cognitive impairment (MCI) is a term used to describe a level of decline in cognition which is seen as an intermediate stage between normal ageing and dementia, and which many consider to be a prodromal stage of neurodegeneration that may become dementia. That is, it is perceived as a high risk level of cognitive change. The increasing burden of dementia in our society, but also our increasing understanding of its risk factors and potential interventions, require diligent management of MCI in order to find strategies that produce effective prevention of dementia. Aim: To update knowledge regarding mild cognitive impairment, and to bring together and appraise evidence abou…
Normative scores for the Timed UpGo in a Spanish sample of community-dweller adults with preserved functionality.
2021
Our aim was to calculate the ‘Timed Up & Go’ (TUG) normative scores in a Spanish sample composed of functional older adults. The TUG test provides a measure of global ambulation skills and its total score has been successfully related with functionality and other important health variables in older adults. Reliable norms are needed for adults 50 years and older that allow the early identification and intervention in motor disturbances. The study was carried out with adults from Galicia and Valencia living in the community. A total of 314 Spanish community-living participants, aged from 50 to 90 years and functionality preserved were assessed through the implementation of a cross-sectional d…

Gender differences in variables associated with sleep quality in chronic tension type headache
2018
We aimed to evaluate gender differences in the relationships between headache features, sleep quality, anxiety, depressive symptoms, and burden of headache in 193 patients (73 percent women) with chronic tension type headache (CTTH). Sleep quality was assessed with the Pittsburgh Sleep Quality Index. Headache features were collected with a four-week diary. The Hospital Anxiety and Depression Scale was used to assess anxiety/depressive symptoms. Headache Disability Inventory was used to evaluate the burden of headache. In men with CTTH, sleep quality was positive correlated with headache frequency (r = 0.310; p = .018), emotional (r = 0.518; p < .001) and physical (r = 0.468; p < .001) burde…
Can Word Puzzles be Tailored to Improve Different Dimensions of Verbal Fluency? A Report of an Intervention Study
2016
Verbal fluency is commonly used as a proxy measure of executive functioning, as it involves cognitive flexibility, working memory, and inhibitory control. Previous research has demonstrated that crosswords can be a useful means of improving verbal fluency, results consistent with the cognitive reserve hypothesis; the form of verbal fluency affected has, however, differed across studies. The present study sought to assess the extent to which it was possible to target phonemic (PVF) and semantic verbal fluency (SVF) separately through word puzzles designed to focus on semantic/thematic and structural clues respectively. Fifty-three university students were randomly assigned to one of three gr…
The small-world of 'Le Petit Prince': Revisiting the word frequency distribution
2016
[EN] Many complex systems are naturally described through graph theory, and different kinds of systems described as networks present certain important characteristics in common. One of these features is the so-called scale-free distribution for its node s connectivity, which means that the degree distribution for the network s nodes follows a power law. Scale-free networks are usually referred to as small-world because the average distance between their nodes do not scale linearly with the size of the network, but logarithmically. Here we present a mathematical analysis on linguistics: the word frequency effect for different translations of the Le Petit Prince in different languages. Compar…
The Effect of Corrective Feedback on Performance in Basic Cognitive Tasks: An Analysis of RT Components
2016
[EN] The current work examines the effect of trial-by-trial feedback about correct and error responding on performance in two basic cognitive tasks: a classic Stroop task (n = 40) and a color-word matching task (n = 30). Standard measures of both RT and accuracy were examined in addition to measures obtained from fitting the ex-Gaussian distributional model to the correct RTs. For both tasks, RTs were faster in blocks of trials with feedback than in blocks without feedback, but this difference was not significant. On the other hand, with respect to the distributional analyses, providing feedback served to significantly reduce the size of the tails of the RT distributions. Such results sugge…

The Impact of Estrogen Decline on Other Noncommunicable Diseases
2017
Estrogens have specific receptors spread out in various systems of the organism. The drastic hormonal fall after menopause may be followed by a series of effects, which may be more or less relevant in the different areas of the organism. The bone constitutes a field that clearly reflects that impact, and postmenopausal osteoporosis has received attention in one ad hoc chapter. The present chapter reviews the impact on functions of the central nervous system, particularly cognition and mood, the skeletal system, specifically osteoarthritis, and the cardiovascular system. The obvious interest of the chapter derives from the importance of the selected systems, which may house highly prevalent …
A Probabilistic Classification Procedure Based on Response Time Analysis Towards a Quick Pre-Diagnosis of Student's Attention Deficit
2019
[EN] A classification methodology based on an experimental study is proposed towards a fast pre-diagnosis of attention deficit. Our sample consisted of school-aged children between 8 and 12 years from Valencia, Spain. The study was based on the response time (RT) to visual stimuli in computerized tasks. The process of answering consecutive questions usually follows an ex-Gaussian distribution of the RTs. Specifically, we seek to propose a simple automatic classification scheme of children based on the most recent evidence of the relationship between RTs and ADHD. Specifically, the prevalence percentage and reported evidence for RTs in relation to ADHD or to attention deficit symptoms were t…
Diagnostic Tools for Autism Spectrum Disorders by Gender: Analysis of Current Status and Future Lines
2021
Studies on the prevalence of autism spectrum disorders have shown gender disproportion. In recent years, there has been an increasing interest in this investigation area. There are two main research lines; the first is focused mostly on gender-related biological reasons that could account for low ASD prevalence in women (i.e., related to some protective factors related to hormones or the immune system, among others), and the second research line studies possible diagnostic biases. In the present study, a review of the latter line of research is made based on two main objectives: (a) analysis of possible biases in diagnostic tools and (b) other nonbiological ASD prevalence explained by gende…

Objective The aim of this study was to analyze critical features that permit the differentiation of subgroups of patients with migraine according to the intensity and frequency of attacks by using machine learning algorithms. Methods Sixty-seven women with migraine participated. Clinical features of migraine, related disability (Migraine Disability Assessment Scale), anxiety/depressive levels (Hospital Anxiety and Depression Scale), anxiety state/trait levels (S…
The Impact of Hormone Therapy on Health
2017
Hormone therapy (HT) has menopausal symptom control as the main indication. However, and because estrogens have receptors spread over many systems in the body, the use of hormones may have consequences on health. Hormone therapy consists of estrogens essentially, since menopausal symptoms mainly derive from estrogen deprivation at different target tissues. However, the normal ovarian cycle includes the regular secretion of progesterone during the days of the luteal phase. Progesterone has a neutralizing effect over endometrial proliferation, this being the reason for adding progestogens to HT formulations in order to protect endometrium. So, guidelines recommend that women with uterus use e…

Relaciones entre variables físicas y de bienestar en la calidad de vida de las personas mayores
2008
De las dimensiones de la calidad de vida -psicologicas, fisicas y sociales-, se analizaron las relaciones entre las dos primeras. Como medida de ABVD se utilizo el Indice de Barthel y, para el bienestar, la LSI-A y las Escalas de Ryff. Se aplicaron a una muestra de 176 jubilados de la provincia de Valencia. Se realizaron correlaciones de Pearson y regresiones jerarquicas, encontrandose relaciones positivas entre el Indice de Barthel y el dominio del ambiente y la satisfaccion general, y negativas con el factor relaciones positivas con otros. Ademas, las variables predictoras del Indice de Barthel son las propias del bienestar subjetivo.
Identification of Subgroups of Women with Carpal Tunnel Syndrome with Central Sensitization.
2016
Identification of subjects with different sensitization mechanisms can help to identify better therapeutic strategies for carpal tunnel syndrome (CTS). The aim of the current study was to identify subgroups of women with CTS with different levels of sensitization.A total of 223 women with CTS were recruited. Self-reported variables included pain intensity, function, disability, and depression. Pressure pain thresholds (PPT) were assessed bilaterally over median, ulnar, and radial nerves, C5-C6 joint, carpal tunnel, and tibialis anterior to assess widespread pressure pain hyperalgesia. Heat (HPT) and cold (CPT) pain thresholds were also bilaterally assessed over the carpal tunnel and the the…

Propiedades psicométricas y estructura factorial del BRCS en una muestra de personas mayores españolas
2015
Successful resilience is a variable often related to an optimal ag-ing process. However, literature is rather limited when dealing with assess-ment instruments for the elderly in the Spanish language. The objective of this work is to validate the Brief Resilient Coping Scale (Sinclair & Wallston, 2004), a four item likert scale, in the Spanish elderly. For this propose, the scale was administrated to a sample of 991 elderly Spanish participants, and the data set analysed in terms of exploratory and confirm-atory factor analysis, internal consistency and criterion validity. The scale demonstrated good psychometric properties. Furthermore, the homogenei-ty indices were higher than the recentl…
Human Reaction Times: Linking Individual and Collective Behaviour Through Physics Modeling
2021
An individual’s reaction time data to visual stimuli have usually been represented in Experimental Psychology by means of an ex-Gaussian function. In most previous works, researchers have mainly aimed at finding a meaning for the parameters of the ex-Gaussian function which are known to correlate with cognitive disorders. Based on the recent evidence of correlations between the reaction time series to visual stimuli produced by different individuals within a group, we go beyond and propose a Physics-inspired model to represent the reaction time data of a coetaneous group of individuals. In doing so, a Maxwell–Boltzmann-like distribution appeared, the same distribution as for the velocities …
The Role of Feedback on Learning: Evidence through Ex-Gaussian Components
2015
Abstract In the performance of any task if a subject does not understand the instructions given they will hardly be able to fulfil the requested goals. The aim of this work was to evaluate the role of feedback through a stroop task for University students. Two experiments were conducted where participants had to perform, into a counterbalanced design, stroop blocks with and without feedback. The classical ANOVA and a fit of the reaction times (RT) into an ex-Gaussian distribution function were carried out. RTs were much lower in feedback blocks than controls. The differences did not reach the statistical significance, however, the parameters often related in the literature to attention in a…
The role of age and emotional valence in word recognition: an ex-gaussian analysis
2015
[Otro] Cie¿om práce je posúdi¿ vplyv veku a emo¿nej valencie na znovupoznávanie slov v rámci ex-Gaussových distribu¿ných komponentov. Dvom vekovým skupinám sme administrovali test znovupoznávania slov, v ktorom sme manipulovali emo¿nou valenciou. U mladších respondentov sa prejavili štatisticky signifikantné rozdiely pri negatívnych slovách v experimentálnej podmienke a v podmienke s distrakciou. U starších respondentov sme v odpove¿ových ¿asoch nezistili jasnú tendenciu. Vzh¿adom na ex-Gaussovský parameter ¿, ktorý sa v literatúre ¿asto spája s nárokmi na pozornos¿, vekovo podmienené rozdiely v emo¿nej valencii nemali žiaden vplyv na negatívne slová. Ak sa zameriame na emo¿nú valenciu v ob…
A happiness degree predictor using the conceptual data structure for deep learning architectures
2017
Abstract Background and Objective: Happiness is a universal fundamental human goal. Since the emergence of Positive Psychology, a major focus in psychological research has been to study the role of certain factors in the prediction of happiness. The conventional methodologies are based on linear relationships, such as the commonly used Multivariate Linear Regression (MLR), which may suffer from the lack of representative capacity to the varied psychological features. Using Deep Neural Networks (DNN), we define a Happiness Degree Predictor (H-DP) based on the answers to five psychometric standardized questionnaires. Methods: A Data-Structure driven architecture for DNNs (D-SDNN) is proposed …
Brain reaction times: Linking individual and collective behaviour through Physics modelling
2019
An individual's reaction time data to visual stimuli have usually been represented in Experimental Psychology by means of an ex-Gaussian function (EGF). In most previous works, researchers have mainly aimed at finding a meaning for the parameters of the EGF function in relation to psychological phenomena. We will focus on interpreting the reaction times (RTs) of a group of individuals rather than a single person's RT, which is relevant for the different contexts of social sciences. In doing so, the same model as for the Ideal Gases (IG) (an inanimate system of non-interacting particles) emerges from the experimental RT data. Both systems are characterised by a collective parameter which is …

2018
Abstract The main purpose of this study is to analyse the psychometric properties of the Satisfaction with Life Scale (SWLS) in a 363 retirees students sample from several Portuguese universities. The 70% were female (253) and 30% were male (110) with an average age of 67 years (SD = 7.59) and a range from 48 to 90 years. R Commander was used for Exploratory Factor Analysis (EFA) and Amos 18.0 module for Confirmatory Factor Analysis (CFA). One factor solution was the best-fitting model. The internal consistency of the SWLS was .777. Correlational analysis showed negative relationships with loneliness (UCLA Scale) and symptoms of depression (GDS-15), supporting concurrent validity. The SWLS …
Estructura factorial y estabilidad de un cuestionario sobre la calidad de un programa de postgrado
2017
In this work we describe an instrument based on the use of a factor analysis technique in order to measure the quality of education within a Postgraduate degree offered by a public Spanish university. We showed that the instrument has satisfactory psychometric properties (reliability and validity). Regarding the factorial solution, three main dimensions have been determined, namely: importance given to the subject; educational resources and knowledge of the subject (previous and posterior). It is important to remark that these three dimensions were consistently detected in all the factorial analyses performed (total sample and separate academic years). These three dimensions should be consi…
