Research on temporal-order perception uses temporal-order judgment (TOJ) tasks or synchrony judgment (SJ) tasks in their binary SJ2 or ternary SJ3 variants. In all cases, two stimuli are presented with some temporal delay, and observers judge the order of presentation. Arbitrary psychometric functions are typically fitted to obtain performance measures such as sensitivity or the point of subjective simultaneity, but the parameters of these functions are uninterpretable. We describe routines in MATLAB and R that fit model-based functions whose parameters are interpretable in terms of the processes underlying temporal-order and simultaneity judgments and responses. These functions arise from an independent-channels model assuming arrival latencies with exponential distributions and a trichotomous decision space. Different routines fit data separately for SJ2, SJ3, and TOJ tasks, jointly for any two tasks, or also jointly for the three tasks (for common cases in which two or even the three tasks were used with the same stimuli and participants). Additional routines provide bootstrap p-values and confidence intervals for estimated parameters. A further routine is included that obtains performance measures from the fitted functions. An R package for Windows and source code of the MATLAB and R routines are available as Supplementary Files. 相似文献

The present study shows that the paradigm relative to Black Sheep Effect (BSE) may be used to reveal normative stakes whose existence is not clearly identified. To this end, our study focuses on alcohol drinking practices among students, specifically with regard to drinking contexts (solitary vs. group). Our hypothesis was that the drinking norms are determined by their context (i.e. social vs. solitary drinking). More specifically, we suggested that social drinking is viewed by students as pro‐normative, while solitary drinking is viewed as anti‐normative. The results confirmed our hypotheses and enable us to consider that the BSE paradigm has the potential to reveal normative stakes. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

The present study investigated whether facial expressions of emotion presented outside consciousness awareness will elicit
evaluative responses as assessed in affective priming. Participants were asked to evaluate pleasant and unpleasant target
words that were preceded by masked or unmasked schematic (Experiment 1) or photographic faces (Experiments 1 and 2) with happy
or angry expressions. They were either required to perform the target evaluation only or to perform the target evaluation
and to name the emotion expressed by the face prime. Prime-target interval was 300 ms in Experiment 1 and 80 ms in Experiment
2. Naming performance confirmed the effectiveness of the masking procedure. Affective priming was evident after unmasked primes
in tasks that required naming of the facial expressions for schematic and photographic faces and after unmasked primes in
tasks that did not require naming for photographic faces. No affective priming was found after masked primes. The present
study failed to provide evidence for affective priming with masked face primes, however, it indicates that voluntary attention
to the primes enhances affective priming. 相似文献

In this research, we applied the operating characteristic of the receiver (ROC) to evaluate item-recognition memory by means of open class words (CA) and closed class words (CC). The purpose was to evaluate memory processes and models, according to the type of stimuli used: words in Spanish, classified according to grammar characteristics. To register the data, a rating scale was applied to obtain the appropriate response levels. Statistically significant differences between the processing of both types of words were obtained. We evaluated models of threshold, continuous, and unequal variance. As a result, we could contribute to the resolution of the present controversy about the models adapted to evaluate the memory of item recognition. Lastly, the differentiation and integration of the models from an empirical point of view is discussed. 相似文献

The Need for Cognitive Closure (NCC) refers to the motivation to seek and maintain a definitive answer to a given problem. This mental closure allows people to avoid confusion, ambiguity and uncertainty. The NCC plays a critical role in a variety of processes of diverse nature, including intra-personal (e.g., the higher the NCC, the less generation of hypothesis), inter-personal (e.g., decreased empathy), intra-group (e.g., increased desire for consensus), and inter-group (increased in-group favouritism) phenomena. The goal of the present research was to provide a Spanish adaptation of Antonio Pierro and Arie Kruglanski's Revised NCC Scale (2005, Rev NfCS), examining the reliability and the validity of participants' scores. In the present studies, it was found that the Spanish version of the scale had acceptable internal reliability and adequate factor structure (Study 1), as well as acceptable test-retest reliability and adequate discriminant validity with regard to the scores in another measure of individual differences such as the Need for Cognition (NC, Study 2). 相似文献

There is some evidence of the relationship between spirituality and quality of life, but there are few bibliographic references on these constructs for patients suffering from mental illness; thus, this study was aimed at revealing the possible role of spiritual outlooks as a protective factor in these individuals. The sample consisted of 96 Portuguese psychiatric patients, selected from a psychiatric hospital and assessed based on parameters for quality of life, spirituality and mindfulness. The data support some theories about the nature of the spirituality. Spiritual beliefs are poorly correlated with the quality of life index, and there is a moderate association between these beliefs and some aspects of mindfulness. It is suggested that a spiritual outlook of psychiatric patients should be taken into account in psychological interventions. 相似文献

Between Remembering and Forgetting the Years of Political Violence: Psychosocial Impact of the Truth and Reconciliation Commission in Peru 下载免费PDF全文

This article analyzes the association between knowledge of the Truth and Reconciliation Commission (TRC), evaluation of TRC's achievements, experience of victimization, attitudes toward remembering and forgetting past political violence, perceptions of socioemotional climate (SEC), belief in forgiveness and attitudes toward violence in Peru based on a study conducted in three Peruvian cities with different rates of victimization due to political violence during 1980–2000 (n = 1200). Results showed that a positive attitude toward remembering the past of political violence was predominant and related to a positive evaluation of TRC's achievements. Attitude toward remembering also has an ambivalent collective effect increasing both positive and negative SECs, and it is less accepted by victims of political violence. On the other hand, attitude toward forgetting is less accepted by participants, and it also has an ambivalent effect by increasing positive and negative SECs. Attitude toward forgetting has more societal costs, since it is related to attitudes toward violence and decreased knowledge and a positive evaluation of TRC. In general, findings suggest that remembering traumatic events has an emotional cost, but also it is shown that remembering seems to be more beneficial for society in the long‐term than forgetting. 相似文献

This article seeks to understand the discourses on motherhood elicited by media in news articles dealing with infanticide. Applying thematic analysis, we studied news and online comments of a Portuguese newspaper. The analysis of infanticidal mothers reports two different images of these mothers both constructed and profiled by the media and the readers. Women are more penalized based on their perversity, living in better economic conditions, being employed and married, whether by the media or by the readers. They are absolved in accordance with their mental illnesses or poor social and economic backgrounds. 相似文献

First, we discuss basic probability notions from the viewpoint of category theory. Our approach is based on the following four “sine quibus non” conditions: 1. (elementary) category theory is efficient (and suffices); 2. random variables, observables, probability measures, and states are morphisms; 3. classical probability theory and fuzzy probability theory in the sense of S. Gudder and S. Bugajski are special cases of a more general model; 4. a good model allows natural modifications. Second, we show that the category ID of D-posets of fuzzy sets and sequentially continuous D-homomorphisms allows to characterize the passage from classical to fuzzy events as the minimal generalization having nontrivial quantum character: a degenerated state can be transported to a nondegenerated one. Third, we describe a general model of probability theory based on the category ID so that the classical and fuzzy probability theories become special cases and the model allows natural modifications. Finally, we present a modification in which the closed unit interval [0,1] as the domain of traditional states is replaced by a suitable simplex. 相似文献

The predictive utility of social cognitive career theory’s (SCCT) interest and choice models was examined in a sample of 600 Portuguese high school students. Participants completed measures of occupational self-efficacy, outcome expectations, interests, social supports and barriers, and choice consideration across the six Holland (1997) RIASEC types. The integrated interest-choice model fit the data well across Holland types and generally supported the hypotheses that self-efficacy and outcome expectations jointly predict interests, and that interests mediate the relations of self-efficacy and outcome expectations to choice consideration. Contrary to SCCT, however, social supports and barriers related to choice consideration indirectly, through self-efficacy, rather than directly. The implications of these findings for further research on the cross-cultural validity of SCCT are considered. 相似文献
