The BRIEF-P is one of the most used instruments to measure Executive Function (EF). This report is aimed at showing the psychometric properties of the Catalan version of it. To do this, a random cluster sampling was carried out in Osona (Catalonia), recruiting 417 teachers and 408 parents of children aged 3 to 6 years. As with the original instrument, results show that reliability is excellent and that girls have a better EF than boys in the following areas: Working Memory, Plan/Organize, and Inhibit. Since in some areas Catalonia's preschool children show EF values slightly better than those of the reference sample, a new scale for using it in this population is provided. 相似文献

This study investigated prospective links between quality of the early caregiving environment and children's subsequent executive functioning (EF). Sixty-two families were met on five occasions, allowing for assessment of maternal interactive behavior, paternal interactive behavior, and child attachment security between 1 and 2 years of age, and child EF at 2 and 3 years. The results suggested that composite scores of parental behavior and child attachment were related to child performance on EF tasks entailing strong working memory and cognitive flexibility components (conflict-EF). In particular, child attachment security was related to conflict-EF performance at 3 years above and beyond what was explained by a combination of all other social antecedents of child EF identified thus far: child verbal ability and prior EF, family SES, and parenting behavior. Attachment security may thus play a meaningful role in young children's development of executive control. 相似文献

Despite growing evidence implicating disgust in the etiology of blood-injection-injury (BII) phobia, the relevance of disgust for exposure-based treatment of BII phobia remains largely unknown. Individuals with BII phobia were randomly assigned to a disgust (view vomit videos) or neutral activation (view waterfall videos) condition. They were then exposed to 14 videotaped blood draws, during which fear and disgust levels were repeatedly assessed. Participants then engaged in a behavioral avoidance test (BAT) consisting of exposure to threat-relevant stimuli. Examination of outcome comparing the identical first and last blood-draw clips revealed that fear and disgust toward blood draws was significantly reduced in both groups. Disgust levels were also found to be more intense for the video stimuli relative to fear levels whereas the opposite was true for BAT stimuli. Contrary to predictions, the disgust induction did not enhance reductions in negative responses to the target video or reduce behavioral avoidance. Growth curve analyses did show that individuals with BII phobia exposed to the disgust induction showed greater initial fear levels during repeated exposure than those in the neutral condition. However, this effect was not consistently observed across different analytic approaches. Changes in fear during exposure were also found to be independent of changes in disgust but not vice versa, and greater initial fear levels during repeated exposure to threat was associated with fear and disgust levels during the BAT. The implications of these findings for conceptualizing the role of disgust in etiology and treatment of BII phobia are discussed. 相似文献

Emotionally arousing events are typically better remembered and more resistant to forgetting than neutral events. Findings from word list paradigms suggest that this may not hold for individuals with Autism Spectrum Disorder (ASD), who also tend to be less accurate as eyewitnesses under some circumstances. To test whether attenuated effects of arousal on memory may be responsible for poorer eyewitness testimonies in ASD, we asked adults with and without the disorder to view either arousing or neutral versions of a narrated slide sequence (Experiment 1) or video clip (Experiment 2) before assessing their memory for the material. Both groups exhibited increases in psychophysiological arousal during the arousing compared with the neutral version of the narratives, and both groups also demonstrated a memory advantage for the arousing events. Contrary to predictions, these observations indicate that stimulus induced arousal modulates memory for naturalistic events relatively typically in ASD.

Researchers often use very abbreviated (e.g., 1-item, 2-item) measures of personality traits due to their convenience and ease of use as well as the belief that such measures can adequately capture an individual's personality. Using data from 2 samples (N = 437 employees, N = 355 college students), we show that this practice, particularly the use of single-item measures, can lead researchers to substantially underestimate the role that personality traits play in influencing important behaviors and thereby overestimate the role played by new constructs. That is, the use of very short measures of personality may substantially increase both the Type 1 and Type 2 error rates. We argue that even slightly longer measures can substantially increase the validity of research findings without significant inconvenience to the researcher or research participants. 相似文献

This article uses meta-analytic methods (k = 38) to examine the relationship between organizational justice climate and unit-level effectiveness. Overall, our results suggest that the relationship between justice and effectiveness is significant (ρ = .40) when both constructs are construed at the collective level. Our results also indicate that distributive justice climate was most strongly linked with unit-level performance (e.g., productivity, customer satisfaction), whereas interactional justice was most strongly related to unit-level processes (e.g., organizational citizenship behavior, cohesion). We also show that a number of factors moderate this relationship, including justice climate strength, the level of referent in the justice measure, the hierarchical level of the unit, and how criteria are classified. We elaborate on these findings and attempt to provide a clearer direction for future research in this area. 相似文献

Culture has been shown to influence response styles. The authors conducted two studies to test the notion that African Americans would be more likely to respond to racism directly, whereas Asian Americans would be more likely to respond indirectly and therefore more subtly. Study 1 showed that Black women subjected to a racist comment from a confederate during an online interaction were more likely than Asian women to verbally reproach the perpetrator. These group differences were not present when the outcome measure was indirect responding--administration of good/bad jellybeans. Study 2 used an online format to demonstrate that Asian women were more likely than Black women to say they would not respond directly to a racist comment. This group difference in unwillingness to confront was significantly mediated by a goal of maintaining peace with their interaction partner. Implications of these findings for the study of discrimination, coping, and well-being are discussed. 相似文献

The study investigated the transfer of attachment working models onto autonomous agents in a virtual social environment (VSE). Participants from a community sample (N = 422; mean age = 29 years; mean relationship duration = 4.8 years) encountered three attachment‐related key scenes in a VSE: a separation with a subsequent reunion, a conflict, and an illness. In these scenarios, participants gave instructions to the main character (the “protagonist”), who had a romantic relationship with one of the other agents (the “virtual spouse”). Recorded were numerous behaviors as well as emotions participants ascribed to the protagonist. Generally, participants' attachment styles correlated as predicted with their behavior toward the virtual spouse, with βs up to.42. Thus, the study demonstrates that internal working models are transferred to the virtual relationship. This approach opens new ways to investigate attachment‐related behavior by using VSEs that allow experimental variations of the virtual partner's reactions and other situational variables. 相似文献

Risk factors for same‐ and other‐sex victimization were examined in a longitudinal data set involving 9‐ to 14‐year‐old students. The findings regarding same‐sex victimization supported the view that bullies select personally and interpersonally vulnerable targets in order to maximize their gains in status while minimizing loss of affection within their same‐sex peer group. Although low self‐esteem was a joint predictor of same‐ and other‐sex victimization, rejection and lack of friends among other‐sex peers failed to predict victimization by other‐sex bullies, and being perceived as popular among other‐sex peers increased the risk. Although the findings suggests that interpersonal risk factors for other‐sex victimization differ from those found for same‐sex victimization, they do not provide strong support for heterosexual interest being the basis for other‐sex target selection, as suggested by some previous literature. As about half of the study participants were involved in the KiVa antibullying program, we had the possibility to examine whether the program effects were similar for same‐ and other‐sex victimization. It turned out that in middle schools the program decreased only same‐sex victimization, whereas in elementary school the decrease was observed regardless of the sex composition of bully–victim dyads.

False negative functional analysis (FA) results may be less likely when caregivers serve as therapists, as problem behavior may be more likely to occur in the presence of a caregiver than with a novel therapist. This case study both replicated and extended prior research on this topic. It provides an example of FA results differing between a caregiver and novel therapist and also showed that FA results may differ across caregivers when they serve as therapists.
