Several studies have shown that the attentional blink (AB; Raymond, Shapiro, & Arnell, 1992) is diminished for highly arousing T2 stimuli (e.g., Anderson, 2005). Whereas this effect is most often interpreted as evidence for a more efficient processing of arousing information, it could be due also to a bias to report more arousing stimuli than neutral stimuli. We introduce a paradigm that allows one to control for such a response bias. Using this paradigm, we obtained evidence that the diminished AB for taboo words cannot be explained by a response bias. This supports the idea that the emotional modulation of the AB is caused by attentional processes. 相似文献

The aim of this study was the adaptation to Spanish of the ?Children's Yale-Brown Obsessive-Compulsive Scale--Self Report? (CY-BOCS-SR), one of the most frequently utilized scales in the assessment of obsessive-compulsive behaviors. After its translation to Spanish, its factor invariance in boys and girls, reliability, and relationship with the children's age were examined. Lastly, normative data for this Spanish version are presented. The sample comprised 1,706 children and adolescents from the general population. Results show that the factor composition of the CY-BOCS-SR does not present a very good fit to the usual scoring of three scales were observed: Obsession Severity, Compulsion Severity, and total score. Results also show that the factor validity and reliability of the CY-BOCS-SR improve remarkably if items related to Resistance to Obsessions and Compulsions are considered a different factor from Severity. It is concluded that the Spanish version of the CY-BOCS-SR has similar psychometric characteristics as the original English version. 相似文献

The assessment of varied psychiatric disorders, including obsessive–compulsive disorder (OCD), is shifting towards the use of evidence-based assessments (EBAs). This shift has fostered the development, validation and adaptation of several measures to rate obsessive–compulsive symptoms and other related problematic areas such as functional impairment or family attitudes among others. The aim of this paper is to present a systematic review of psychometric studies on pediatric OCD-specific measures to classify these according to assessment evidence-based criteria. Selection criteria that determined which studies were included in the review were: (1) analyzing an OCD measure and (2) including participants’ age being 18 years or younger. The literature search procedure was conducted in Medline, PsycINFO, PsycARTICLES, ERIC, Cochrane Library, and Scholar Google databases and enabled us to locate 42 studies which analyzed psychometric properties of 14 OCD measures studied in children and adolescents. Instruments were grouped into the following assessment areas: symptom presence and severity, functional impairment, family functioning and cognitive dimensions of OCD. Psychometric data regarding internal structure, internal consistency, reliability, validity and diagnostic precision were also reported. Further, measures were classified as well-established, approaching well-established and promising assessments in terms of reliability and validity. We concluded that the assessment of OCD in pediatric populations is a growing field that in a short-medium term could provide a wide variety of EBAs for the evaluation obsessive–compulsive symptoms and other OCD-related dimensions. The paper concludes by highlighting directions for future research. 相似文献

Investigating eye movements has been a promising approach to uncover the role of visual working memory in early attentional processes. Prior research has already demonstrated that eye movements in search tasks are more easily drawn toward stimuli that show similarities to working memory content, as compared with neutral stimuli. Previous saccade tasks, however, have always required a selection process, thereby automatically recruiting working memory. The present study was an attempt to confirm the role of working memory in oculomotor selection in an unbiased saccade task that rendered memory mechanisms irrelevant. Participants executed a saccade in a display with two elements, without any instruction to aim for one particular element. The results show that when two objects appear simultaneously, a working memory match attracts the first saccade more profoundly than do mismatch objects, an effect that was present throughout the saccade latency distribution. These findings demonstrate that memory plays a fundamental biasing role in the earliest competitive processes in the selection of visual objects, even when working memory is not recruited during selection. 相似文献

Leader distance theory has received scant empirical attention in the extant literature; however, the “work from home” orders associated with COVID-19 have made this theory and its empirical findings highly relevant for organizations. Our study integrates leader distance theory and followership theory to understand how follower role beliefs affect follower effort, performance, and withdrawal under physical leader distance and varying conditions of leader interaction frequency. Using a three-wave survey methodology with 260 adults working remotely, our study finds that followers' levels of effort, performance, and withdrawal were contingent on leader interaction frequency. Specifically, followers with a coproduction role orientation, who see their role as more collaborative, reported higher levels of effort under conditions of high leader interaction. Furthermore, the indirect effect of coproduction on follower performance and withdrawal via effort was moderated by leader interaction frequency. The results for followers with passive role orientations, however, were in the opposite direction. These followers reported less effort when leader interaction was high, and the mediational chain predicting performance and withdrawal was contingent on leader interaction frequency. Our study contributes to the ongoing conversation about the positive and negative effects of leader distance and positions followership characteristics as important boundary conditions of distal leadership. 相似文献
