Fontu veidu ietekme saskarņu uztverē

2020

Saskarnēs, veidojot to saturu, teksts ir ne tikai galvenais informācijas avots, bet arī tās estētiskā tēla veidotājs. Tas ir iespējams, attēlojot tekstu kādā no fontiem. Tādēļ ir svarīgi apzināties fontu ietekmi un to nozīmi. Bakalaura darba mērķis ir izpētīt fontu ietekmi uz cilvēka afektīvo profilu, kā arī sniegt ieteikumus optimālā fonta izvēlē, izrietot no cilvēka demogrāfiskajām īpatnībām. Balstoties uz darbā aplūkoto literatūru un citu pētījumu rezultātiem, tika izstrādāts eksperiments PsychoPy rīkā, kas ir balstīts Python programmēšanas valodā. Eksperimenta laikā tika mērīts reakcijas laiks, izvēloties patīkamāko fontu no 14 dažādiem fontu pāriem, kā arī mērīti novērtējumi 10 dažādie…

Heart rate variability and self-control—A meta-analysis

2015

Heart rate variability (HRV) has been suggested as a biological correlate of self-control. Whereas many studies found a relationship between HRV at rest and self-control, effect sizes vary substantially across studies in magnitude and direction. This meta-analysis evaluated the association between HRV at rest and self-control in laboratory tasks, with a particular focus on the identification of moderating factors (task characteristics, methodological aspects of HRV assessment, demographics). Overall, 24 articles with 26 studies and 132 effects (n=2317, mean age=22.44, range 18.4-57.8) were integrated (random effects model with robust variance estimation). We found a positive average effect …

Letter Position Coding Across Modalities: The Case of Braille Readers

2012

BackgroundThe question of how the brain encodes letter position in written words has attracted increasing attention in recent years. A number of models have recently been proposed to accommodate the fact that transposed-letter stimuli like jugde or caniso are perceptually very close to their base words.MethodologyHere we examined how letter position coding is attained in the tactile modality via Braille reading. The idea is that Braille word recognition may provide more serial processing than the visual modality, and this may produce differences in the input coding schemes employed to encode letters in written words. To that end, we conducted a lexical decision experiment with adult Braille…

Emotional deficit as a neuropsychopathological disturbance in HIV infection

2001

We have been very interested in the article of Castellon et al. (2000) on the neuropsychiatric disturbances present in HIV-infection, which reports results very congruent with those published previously by our research group. Indeed, for many years we have studied psychopathological perturbations (depression and anxiety) as well as more specific emotional dimensions like emotional deficit and loss of control in HIV positive patients.

T110. FIRST EPISODE PSYCHOTIC PATIENTS WITH A HISTORY OF FREQUENT CANNABIS USE EXPRESS MORE POSITIVE SYMPTOMS AT ILLNESS ONSET THAN THOSE WHO NEVER U…

2018

Abstract Background Robust evidence has demonstrated that cannabis use increases the risk to develop psychotic disorders. However, a limited number of studies have investigated if and how cannabis use influences psychopathology profiles at first episode psychosis (FEP). Based on the evidence that dopamine dysfunction contributes to explain positive symptoms in psychosis, and that the main cannabis’ psychoactive component, Δ9-Tetrahydrocannabinol (THC), modulates the dopamine system, we hypothesise that: 1) positive symptoms at FEP are more common among psychotic patients who used cannabis compared with never users; 2) this association is a dose-response relationship. Methods We analyzed a s…

Cue combination in a combined feature contrast detection and figure identification task

2006

AbstractTarget figures defined by feature contrast in spatial frequency, orientation or both cues had to be detected in Gabor random fields and their shape had to be identified in a dual task paradigm. Performance improved with increasing feature contrast and was strongly correlated among both tasks. Subjects performed significantly better with combined cues than with single cues. The improvement due to cue summation was stronger than predicted by the assumption of independent feature specific mechanisms, and increased with the performance level achieved with single cues until it was limited by ceiling effects. Further, cue summation was also strongly correlated among tasks: when there was …

Psychological aspects in children affected by duchenne de boulogne muscular dystrophy.

2012

Impairment of intelligence in Duchenne muscular dystrophy (DMD) patients was described by Duchenne de Boulogne himself in 1868. Further studies report intelligence disorders with mayor impairment of memory. The aim of the present study was to assess the presence of affective and personality disorders in a group of children affected by DMD. Twenty six male DMD patients, mean age eleven and four months years old, were assessed for their affective and personality disorder. Only eight subjects had a total IQ below average with major difficulties in verbal and visual-spatial memory, comprehension, arithmetic and vocabulary. All the subjects presented some disorders: tendency to marginalization a…

Sensación de inacabado y experiencias “not just right” como motivadoras de los síntomas obsesivo-compulsivos

2016

The sense of incompleteness, “not just right” experiences and “just right” symptoms are considered motivational variables of obsessive-compulsive symptoms. This study examines the relationships between these “new” constructs and Obsessive-Compulsive Disorder (OCD) related variables (symptoms, dysfunctional beliefs, perfectionism, and intolerance to uncertainty), in comparison to its association with emotional non-OCD psychopathology. The results from 267 individuals who completed self-reports indicate that individuals at risk of developing OCD score higher on the main constructs of the study than those not at risk. Only the variables incompleteness, not just right experiences and just right…

Virtual Reality in Marketing: A Framework, Review, and Research Agenda

2019

[EN] Marketing scholars and practitioners are showing increasing interest in Extended Reality (XR) technologies (XRs), such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), as very promising technological tools for producing satisfactory consumer experiences that mirror those experienced in physical stores. However, most of the studies published to date lack a certain measure of methodological rigor in their characterization of XR technologies and in the assessment techniques used to characterize the consumer experience, which limits the generalization of the results. We argue that it is necessary to define a rigorous methodological framework for the use of XRs in ma…
