Both contextual regularity and selective attention affect the reduction of precision‐weighted prediction errors but in distinct manners
2020
Predictive coding model of perception postulates that the primary objective of the brain is to infer the causes of sensory inputs by reducing prediction errors (i.e., the discrepancy between expected and actual information). Moreover, prediction errors are weighted by their precision (i.e., inverse variance), which quantifies the degree of certainty about the variables. There is accumulating evidence that the reduction of precision-weighted prediction errors can be affected by contextual regularity (as an external factor) and selective attention (as an internal factor). However, it is unclear whether the two factors function together or separately. Here we used electroencephalography (EEG) …
Identifying musical pieces from fMRI data using encoding and decoding models.
2018
AbstractEncoding models can reveal and decode neural representations in the visual and semantic domains. However, a thorough understanding of how distributed information in auditory cortices and temporal evolution of music contribute to model performance is still lacking in the musical domain. We measured fMRI responses during naturalistic music listening and constructed a two-stage approach that first mapped musical features in auditory cortices and then decoded novel musical pieces. We then probed the influence of stimuli duration (number of time points) and spatial extent (number of voxels) on decoding accuracy. Our approach revealed a linear increase in accuracy with duration and a poin…
Effects of grip and push forces on the acute response of the hand-arm system under vibrating conditions
1993
The purpose of the occupational medicine component of a joint research project was to study the effects of grip and push forces on the acute reaction of the hand-arm system under vibrating conditions. Several series of experiments were carried out by means of a vibration simulator in a laboratory environment in order to study biodynamic vibration behaviour, muscle response, skin temperature, shifts of the vibration perception threshold and the intensity of subjective vibration perception; in addition, field tests with hammer drills were conducted. On the whole, the findings obtained suggest that the coupling of the hand with the handle involved in using vibrating tools has a considerable im…
Role of sensorimotor areas in early detection of motor errors: An EEG and TMS study
2019
Abstract Action execution is prone to errors and, while engaged in interaction, our brain is tuned to detect deviations from what one expects from other’s action. Prior research has shown that Event-Related-Potentials (ERPs) are specifically modulated by the observation of action mistakes interfering with goal achievement. However, in complex and modular actions, embedded motor errors do not necessarily produce an immediate effect on the global goal. Here we dissociate embedded motor goals from global action goals by asking subjects to observe familiar but untrained knotting actions. During knotting an embedded motor error (i.e. the rope is inserted top-down instead of bottom-up during the …
The association between stress mindset and physical and psychological wellbeing: testing a stress beliefs model in police officers.
2020
Objective: Emergency service workers like police officers experience high levels of stress in the course of their regular duties. Holding particular stress mindsets may help to mitigate the deleter...
Idendity development, coping, and adjustment in emerging adults with a chronic illness: the sample case of type 1 diabetes
2008
Abstract Purpose The present study focused on identity development in emerging adults (aged 18–30 years) with type 1 diabetes. The three study aims were to examine the following: (1) whether identity development was affected by having diabetes, as compared with development in a nondiabetic sample; (2) how identity development was related to depressive symptoms, coping with diabetes, and diabetes-related problems in the diabetic sample; and (3) whether the pathways from identity development to problems with diabetes and depressive symptoms were mediated through coping strategies in the diabetic sample. Methods A total of 194 emerging adults with type 1 diabetes and 344 nondiabetic emerging a…
Factors Related to Women’s Psychological Distress during the COVID-19 Pandemic: Evidence from a Two-Wave Longitudinal Study
2021
Background. A growing body of research has highlighted the negative effects of the COVID-19 pandemic on women’s mental health. Previous studies showed that women have higher levels of depression, anxiety and PTSD, and worse psychological adjustment than men, which also persisted after the earlier phase of the pandemic. This study aimed to evaluate changes in women’s psychological distress during the pandemic and to evaluate the factors that have a more significant impact in predicting women’s psychological distress. Methods. This two-wave longitudinal study (T1 = Italian first lockdown, and T2 = second phase, when the restrictive measures were eased) involved 893 women (Mage = 36.45, SD = 1…
Nurses´ stressors and psychological distress during the COVID‐19 pandemic: The mediating role of coping and resilience
2021
This study analyses the cross-sectional effect of sources of stress during the peak of COVID-19 pandemic on nurses´ psychological distress, focusing on the mediating role of coping strategies, both problem focused and emotion focused and resilience.Cross-sectional and quantitative analyses.Structural equation modelling was performed using survey data obtained during the period between 1 April-25 May 2020 in a sample of 421 nurses from 39 Spanish provinces.Results confirmed that: (a) All the stressors have a significant, direct, and negative relationship with nurses´ psychological distress; (b) Emotion-focused strategies is negatively related to nurses´ psychological distress directly and in…
Palliative Cancer Patients’ Experiences of Participating in a Lifestyle Intervention Study While Receiving Chemotherapy
2015
Background Lifestyle interventions have promise in terms of their potential health benefits and as an empowerment tool for cancer patients. Nevertheless, documentation of palliative cancer patients experiences of participating in lifestyle interventions remains poor. Objective The objective of this study was to explore how palliative cancer patients experience participation in a feasibility study focusing on multiple lifestyle interventions (physical, nutritional, smoking cessation, and stress management) while receiving chemotherapy. Methods This was a qualitative design with semistructured interviews of 9 palliative cancer patients 3 to 4 months after inclusion to the lifestyle interventi…
A translational approach to design effective intervention tools for informal caregivers of dependent cancer patients.
2019
OBJECTIVES: Caregivers of terminal patients often report a higher prevalence of unmet needs than cancer survivors. However, very few interventions have been carried out to support caregivers of patients in advanced stages, and, in most cases, they have not been rigorously designed and evaluated. The ultimate aim of this research was to obtain specific information about the sociodemographic characteristics, the different types of care provided, the symptoms due to burdens, the impact of caring on the quality of life, and the unmet needs of informal caregivers of dependent patients with cancer. This is to design effective intervention programs that can be implemented from the hospital setting…
