Research on the perception of temporal order uses either temporal-order judgment (TOJ) tasks or synchrony judgment (SJ) tasks, in both of which two stimuli are presented with some temporal delay and observers must judge the order of presentation. Results generally differ across tasks, raising concerns about whether they measure the same processes. We present a model including sensory and decisional parameters that places these tasks in a common framework that allows studying their implications on observed performance. TOJ tasks imply specific decisional components that explain the discrepancy of results obtained with TOJ and SJ tasks. The model is also tested against published data on audiovisual temporal-order judgments, and the fit is satisfactory, although model parameters are more accurately estimated with SJ tasks. Measures of latent point of subjective simultaneity and latent sensitivity are defined that are invariant across tasks by isolating the sensory parameters governing observed performance, whereas decisional parameters vary across tasks and account for observed differences across them. Our analyses concur with other evidence advising against the use of TOJ tasks in research on perception of temporal order. 相似文献

OBJECTIVE: To evaluate the clinical features of obsessive-compulsive disorder (OCD) patients with comorbid tic disorders (TD) in a large, multicenter, clinical sample.MethodA cross-sectional study was conducted that included 813 consecutive OCD outpatients from the Brazilian OCD Research Consortium and used several instruments of assessment, including the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, the Yale Global Tic Severity Scale (YGTSS), the USP Sensory Phenomena Scale, and the Structured Clinical Interview for DSM-IV Axis I Disorders. RESULTS: The sample mean current age was 34.9 years old (SE 0.54), and the mean age at obsessive-compulsive symptoms (OCS) onset was 12.8 years old (SE 0.27). Sensory phenomena were reported by 585 individuals (72% of the sample). The general lifetime prevalence of TD was 29.0% (n = 236), with 8.9% (n = 72) presenting Tourette syndrome, 17.3% (n = 141) chronic motor tic disorder, and 2.8% (n = 23) chronic vocal tic disorder. The mean tic severity score, according to the YGTSS, was 27.2 (SE 1.4) in the OCD + TD group. Compared to OCD patients without comorbid TD, those with TD (OCD + TD group, n = 236) were more likely to be males (49.2% vs. 38.5%, p < .005) and to present sensory phenomena and comorbidity with anxiety disorders in general: separation anxiety disorder, social phobia, specific phobia, generalized anxiety disorder, post-traumatic stress disorder, attention-deficit hyperactivity disorder, impulse control disorders in general, and skin picking. Also, the "aggressive," "sexual/religious," and "hoarding" symptom dimensions were more severe in the OCD + TD group.ConclusionTic-related OCD may constitute a particular subgroup of the disorder with specific phenotypical characteristics, but its neurobiological underpinnings remain to be fully disentangled. 相似文献

IntroductionAttention-deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD) are frequently co-occurring disorders in children and adolescents. However, their clinical status among adults is still under discussion. This study analyzes how the current clinical presentation of adult ADHD might be influenced by a lifetime history of CD and ODD. METHODS: We compared three groups of patients: ADHD without history of CD/ODD (n = 178), ADHD + history of ODD (n = 184), and ADHD + history of CD (n = 96). RESULTS: A history of CD (and to a lower extent ODD) is associated with a more severe and externalizing profile.ConclusionPast CD and ODD entail a significant negative mental health impact on persistent ADHD, reinforcing the importance of actively assessing the developmental history of adult ADHD patients. 相似文献

There is a phenomenon contributing to the current pattern of alcohol consumption among youngsters in Spain known as "botellon". From research financed by the National Plan on Drugs (2004-2007), data of 6009 youngsters (14-25 years old) were collected from three Spanish cities. Only individuals who engage in intensive consumption of alcohol (n = 2807) have been included. The purpose of this work has been to identify the different types of consumers at risk through a cluster analysis and to establish a profile for each particular group. Four groups were differentiated by age, gender, alcohol consumption and years of consumption. It was observed that adolescent students and university students of the same sex consume similar quantities of alcohol, and justify their consumption alluding to personal factors, whereas university students refer to issues related to control of leisure. The consumption by males is the highest, and they are the most likely to seek drunkenness. They associate to a lesser degree their consumption with the possibility of developing an addictive process. In general, all youngsters consider that their consumption will have no negative consequences. These results indicate the need to come up with different alternatives, addressing the particularities of each group. 相似文献

This is the first study developed in Portugal which investigates specific characteristics of dance and gymnastics environments that make them high-risk contexts for the development of eating disorders. Four focus groups were conducted with thirteen ballet students from a professional dance school and nine gymnasts from a gymnastics club (aged 12 to 17 years old), which were subjected to an inductive-deductive analysis procedure. Specific risk and protective factors were identified. Among their respective sources of influence, teachers and coaches are those who exert a stronger influence upon young athletes. We also explored some themes related to the influence of peers, parents, and environmental characteristics, which could have an important role on the development or prevention of disordered eating. 相似文献

To effectively wayfind through unfamiliar buildings, humans infer their relative position to target locations not only by interpreting geometric layouts, especially length of line of sight, but also by using background knowledge to evaluate landmarks with respect to their probable spatial relation to a target. Questionnaire results revealed that participants have consistent background knowledge about the relative position of target locations. Landmarks were rated significantly differently with respect to their spatial relation to targets. In addition, results from a forced-choice task comparing snapshots of a virtual environment revealed that background knowledge influenced wayfinding decisions. We suggest that landmarks are interpreted semantically with respect to their function and spatial relation to the target location and thereby influence wayfinding decisions. This indicates that background knowledge plays a role in wayfinding. 相似文献

Unlike most infectious diseases, COVID-19 is characterised by an absence of facial disease-signalling cues. Yet, it is still unclear whether it has influenced face perception. Understanding this may help clarify if and how our motivation toward social interactions is conditional on situational pathogen threats. The present study investigated if priming disease concerns about COVID-19 would change people's perception of neutral faces on perceived disease, social discomfort and arousal elicited by such faces; this condition was compared with other infectious/non-infectious diseases and a non-disease priming condition. One-hundred sixty-six participants recruited nationally performed the online task. When compared with the non-disease condition, participants primed for COVID-19 perceived faces as sicker and tended to view them as eliciting more social discomfort; no difference occurred in arousal. No other difference was found between conditions. These findings suggest that the pandemic context can shape how we perceive others' apparent sickness. Overall, these might reflect adaptations intertwined with the behavioural immune system's defence mechanisms. 相似文献

Abstract This paper describes a body of theory which points to the possibility that eating disorders can be seen as psychosomatic illness, which is to say a symbolization of affect via the body rather than with words. The author concludes from this that eating disorders may respond better to non-verbal experiential therapies than they do to verbal therapy. She then describes four years of work with groups of eating-disordered women using non-verbal experiential therapies and suggests that the improvement in their symptoms may be the result of these methodologies and that her hypothesis merits further testing and exploration. 相似文献

The encounter with clients from diverse cultural backgrounds may stir in the practitioners intense counter-transferencial reactions, which if unexplored may obstruct the helping relationships and interventions. This article presents and demonstrates a cultural competence training where such countertransference can be worked through. The training applies a combination of narrative analysis that emphasizes the active participation of the listener in the sense-making process and of the exploration of group processes from a psychoanalytically oriented point of view. Presented are four vignettes that demonstrate different types of countertransference and of the group process. 相似文献

This article examines psychosocial aspects of family/parent-child relationships during the Holocaust by focusing on the emotional memories of such relationships. Global and thematic analyses were undertaken on 93 life story interviews and testimonies with Holocaust survivors. Results showed that survivors who lived through most of the war with parents/family and those who had lived approximately an equal time with loved ones and without them were able to recall and narrate more emotional memories, both positive and negative, than people who had experienced the traumatic period mostly on their own. However, going through the war with family did not guarantee the narration of emotional memories; close to half of these victims could not recall/narrate such memories. In general, when the survivor recalled relative emotional security, she or he felt safe, even when physical danger was imminent. However, this feeling did not always continue when the physical situation worsened or when the survivor was separated from loved ones. It was suggested that the ability to recall and narrate emotional memories highlights the heterogeneity in family relationships that existed during the Holocaust and the kinds of family relationships that developed after the Holocaust. 相似文献
