The following study examines the relationship between verbal memory deficits and schizotypal traits measured psychometrically from a non- clinical adolescent population. In this transversal analytical study participated 139 subjects. They were secondary school students, with ages ranging from 13 to 16 years old (mean= 14, 35; Sta.Dev.= 0, 548). After administrating the scales O-LIFE (psychometrical schizotypy), CVLT (verbal memory), and Letters and Numbers subtest of WAIS-III (working memory), data was analyzed utilizing Pearson correlations and mean comparison test. Results showed lack of relations between schizotypy measures and working memory. Nonetheless, some of the O-LIFE dimensions correlated with verbal memory. These findings support partly the literature reviewed. Yet, more work focused on schizotypy and cognitive deficits as risk factors are suggested. 相似文献

The present study outlines the development process of two scales that measure general and specific retribution practices in organisations. Historically, retribution has been the subject of research of other social sciences such as Sociology and Business Administration. In Psychology, and more specifically in Work and Organisational Psychology, there are hardly any studies or inventories designed to evaluate retribution practices. In order to accomplish the objectives, a sample of 237 employees was selected, 42.6% of whom were women and 57.4% were men. We performed and exploratory factorial analysis using principal axis factoring as extraction method and an oblique rotation (oblimin) to analyse the two scales. The former is made up of four factors and the latter is a two-factor scale. The reliability coefficients of the six subscales we obtained ranged between .72 and .89. External validity was analysed using the correlations obtained between the two inventories and the Balanced Scorecard. The two tools were found to be two potentially useful scales to evaluate retribution practices. 相似文献

This paper attempts to show how the “big data” paradigm is changing science through offering access to millions of database elements in real time and the computational power to rapidly process those data in ways that are not initially obvious. In order to gain a proper understanding of these changes and their implications, we propose applying an extended cognition model to the novel scenario. 相似文献

The cognitive regulation of emotions is important for human adaptation. Self‐focused emotion regulation (ER) strategies have been linked to the development and persistence of anxiety and depression. A vast array of research has provided valuable knowledge about the neural correlates of the use of specific self‐focused ER strategies; however, the resting neural correlates of cognitive ER styles, which reflect an individual's disposition to engage in different forms of ER in order to manage distress, are largely unknown. In this study, associations between theoretically negative ER style (self‐focused or not) and the complexity (fractal dimension, FD) of the resting EEG at frontal, central, parietal, and occipital regions were investigated in 58 healthy volunteers. The Cognitive Emotion Regulation Questionnaire was used as the self‐report measure of ER style. Results showed that a diminished FD over the scalp significantly correlated with self‐focused ER style scores, even after controlling for negative affect, which has been also considered to influence the use of ER strategies. The lower the EEG FD, the higher were the self‐focused ER style scores. Correlational analyses of specific self‐focused ER strategies showed that self‐blaming and rumination were negatively associated with diminished FD of the EEG, but catastrophizing and blaming others were not. No significant correlations were found for ER strategies more focused on situation or others. Results are discussed within the self‐organized criticality theory of brain dynamics: The diminished FD of the EEG may reflect a disposition to engage in self‐focused ER strategies as people prone to ruminate and self‐blame show a less complex resting EEG activity, which may make it more difficult for them to exit their negative emotional state. 相似文献

E. S. Barratt proposed the term impulsive aggression to define a kind of aggression that is characterized by acting without thinking because of high levels of impulsivity. Previous research using psychometric measures has shown that impulsivity and aggression are related as far as psychometric measures are concerned. Nevertheless, most of the research has been done with samples of university students. Our research tests whether this relationship is stable across different samples; university students, teenagers and workers. Our results show that impulsivity and aggression have a consistent pattern of relationships across these samples, with impulsivity being specially related to emotional and instrumental aspects of aggression. Furthermore, the effects of anger on aggression seem to show a pattern of relationship that depends on age, with a tendency to physical aggression in young people and verbal aggression in adults. 相似文献

The purpose of this essay is to clarify the notion of mnemonic content. Memories have content. However, it is not clear whether
memories are about past events in the world, past states of our own minds, or some combination of those two elements. I suggest
that any proposal about mnemonic content should help us understand why events are presented to us in memory as being in the
past. I discuss three proposals about mnemonic content and, eventually, I put forward a positive view. According to this view,
when a subject seems to remember a certain event, that event is presented to her as making true a perceptual experience that
caused the very memory experience that she is having.

We report the naming performance of an early and highly proficient Spanish-Catalan bilingual (JPG) suffering from Primary Progressive Aphasia (PPA). JPG's performance revealed a grammatical category-specific deficit, with worse performance in naming verbs than nouns. This dissociation was present in oral and written naming and in his two languages, and it seems to stem from damage to, at least, the lexical level. Despite the fact that JPG's performance was qualitatively very similar across languages, his second language seemed to be more affected than his first language. These results indicate that the cortical organization of the two languages of highly proficient bilinguals follow similar organizational principles, one of this principles being grammatical class. 相似文献

Abstract A longitudinal study with three periods of data collection has been designed to test a model concerning the antecedents and consequences of coping in the anticipatory stage of an examination stress process. The model tested focuses on the role of positive and negative affect at an early stage as the main antecedents for coping. Primary and secondary appraisal, and dispositional variables (perceived personal competence and optimism) have been related to early affect. Moreover, the consequences of coping, considered as the affect measured after the deployment of coping strategies, and the grade obtained in the exam, are also tested. Results show that early affect is the main antecedent of displayed coping strategies. Dispositional variables and appraisal are related to affect, and differential effects of coping in later affect have been noticed. No relationship between coping and grade has been found. Implications for research on coping with examination stress are discussed. 相似文献

Developmental studies of mental disorders based on epidemiological data are often based on cross-sectional retrospective surveys. Under such designs, observations are right-censored, causing underestimation of lifetime prevalences and correlations, and inducing bias in latent trait models on the observations. In this paper we propose a Partial Likelihood (PL) method to estimate unbiased IRT models of lifetime predisposition to develop a certain outcome. A two-step estimation procedure corrects the IRT likelihood of outcome appearance with a function depending on (a) projected outcome frequencies at the end of the risk period, and (b) outcome censoring status at the time of the observation. Simulation results showed that the PL method yielded good recovery of true frequencies and intercepts. Slopes were best estimated when events were sufficiently correlated. When PL is applied to lifetime mental health disorders (assessed in the ESEMeD project surveys), estimated univariate prevalences were, on average, 1.4 times above raw estimates, and 2.06 higher in the case of bivariate prevalences. 相似文献

A haptic pedal has been designed to emulate the behaviour of a common vehicle pedal and render superimposed vibrations with different characteristics. It was installed in a driving simulator, as an accelerator pedal with the secondary function of a vibrotactile Frontal Collision Warning (FCW). The efficacy and feeling of this solution was tested with 30 subjects using vibrotactile signals with 0.50, 1.05, and 1.60 Nm, at 2.5, 5, and 10 Hz, against a baseline visual FCW. Participants had to match the speed of a leading vehicle when the FCW was triggered. Their braking response was evaluated in terms of brake reaction time, matching speed time, control of velocity and headway reduction. Driver’s feelings were assessed with Kansei methodologies. Haptic stimuli were found to be more effective than visual signals, and the characteristics of the vibration also influenced the results. The best performance was achieved at the maximum amplitude, and in the range between 5 and 10 Hz. The perceived functionality and discomfort followed a trend coherent with the objective measurements. The conclusions of this study may be applied to develop effective and safe warning systems in vehicles, limiting the annoyance that they might cause to drivers. 相似文献
