This commentary considers the paper by Furley and Memmert (2010) who sought to test the respective validities of the specific processing and cognitive adaptation hypotheses. That they found no evidence of a difference between experienced basketball players and nonathletes on the Corsi block task, a measure of spatial memory, led them to infer support for the specific processing hypothesis, namely that differences between experts and novices manifest themselves only in processes related specifically to the domain of expertise. An alternative interpretation is offered, indicating possible confounds and referring to recent research that suggests Corsi block and dynamic spatial tasks depend upon different neuronal networks.  相似文献

In the face of prejudice against an ingroup, common ground for communication exists when people use similar social categories to understand the situation. Three studies tested the hypothesis that describing perceptions of prejudice can fundamentally change those perceptions because communicators account for the common ground in line with conversational norms. When women (Study 1), African Americans (Study 2), and Americans (Study 3) simply thought about suspected prejudice against their ingroup, categorization guided their perceptions: Participants assimilated their views of the prejudiced event toward the perceptions of ingroup members but contrasted away from the perceptions of outgroup members. Conversely, when participants described their perceptions, they contrasted away from the given category information and actually arrived at the opposite perceptions as those who merely thought about the prejudiced event. Study 3 identified an important qualification of these effects by showing that they were obtained only when participants could assume their audience was familiar with the common ground. Implications are discussed for understanding the role of communication in facilitating and inhibiting collective action about prejudice.  相似文献

This article examines the role that personality variables and processes play in people's efforts to manage their public images. Although most research on self-presentation has focused on situational influences, people differ greatly in the degree to which they care about others' impressions of them, the types of impressions they try to convey, and their evaluations of their self-presentational effectiveness. Personality constructs such as public self-consciousness, approval motivation, and fear of negative evaluation are associated with the motive to manage one's impressions, and people who differ in self-disclosure and desire for privacy differentially reveal information about themselves to others. Other variables relating to people's self-concepts, interpersonal goals, and traits influence the construction of specific images. Finally, the extent to which people believe they are capable of making desired impressions influences their impression management strategies and how they respond to other people's evaluations.  相似文献

Mosaic chromosomal abnormalities are relatively common. However, mosaicism may be missed due to multiple factors including failure to recognize clinical indications and order appropriate testing, technical limitations of diagnostic assays, or sampling tissue (s) in which mosaicism is either not present, or present at very low levels. Blood leukocytes have long been the “gold standard” sample for cytogenetic analysis; however, the culturing process for routine chromosome analysis can complicate detection of mosaicism since the normal cell line may have a growth advantage in culture, or may not be present in the cells that produce metaphases (the lymphocytes). Buccal cells are becoming increasingly utilized for clinical analyses and are proving to have many advantages. Buccal swabs allow for simple and noninvasive DNA collection. When coupled with a chromosomal microarray that contains single nucleotide polymorphic probes, analysis of buccal cells can maximize a clinician’s opportunity to detect cytogenetic mosaicism. We present three cases of improved diagnosis of mosaic aberrations using buccal specimens for chromosomal microarray analysis. In each case, the aberration was either undetectable in blood or present at such a low level it likely could have gone undetected. These cases highlight the limitations of certain laboratory methodologies for identifying mosaicism. We also present practice implications for genetic counselors, including clinic workflow changes and counseling approaches based on increasing use of buccal samples.  相似文献

Parental presence is often employed to alleviate distress in children within the context of surgery under general anesthesia. The critical component of this intervention may not be the presence of the parent per se, but more importantly the behaviors in which the parent and child engage when the parent is present. The purpose of the current study was to examine the sequential and reciprocal relationships between parental behaviors and child distress during induction of general anesthesia. Participants were 32 children (3–6 years) receiving dental surgery as a day surgery procedure, and their parents. A modified Child Adult Medical Procedures Interaction Scale-Revised was used to code parent and child behaviors. Initial child distress led to increased parental provision of reassurance and decreased provision of physical comfort. Our findings may inform the development of preoperative preparation programs whereby parents can be appropriately educated about what behaviors will be helpful/unhelpful for their child during induction of general anesthesia.  相似文献

Optimal cognitive ability is likely important for military working dogs (MWD) trained to detect explosives. An assessment of a dog’s ability to rapidly learn discriminations might be useful in the MWD selection process. In this study, visual discrimination and reversal tasks were used to assess cognitive performance in Labrador retrievers selected for an explosives detection program using a modified version of the Toronto General Testing Apparatus (TGTA), a system developed for assessing performance in a battery of neuropsychological tests in canines. The results of the current study revealed that, as previously found with beagles tested using the TGTA, Labrador retrievers (N = 16) readily acquired both tasks and learned the discrimination task significantly faster than the reversal task. The present study confirmed that the modified TGTA system is suitable for cognitive evaluations in Labrador retriever MWDs and can be used to further explore effects of sex, phenotype, age, and other factors in relation to canine cognition and learning, and may provide an additional screening tool for MWD selection.  相似文献

The resolution of temporal attention is limited in a manner that makes it difficult to identify two targets in short succession. This limitation produces the phenomenon known as the attentional blink (AB), in which processing of a first target (T1) impairs identification of a second target (T2). In the AB literature, there is broad agreement that increasing the time it takes to process T1 leads to a larger AB. One might, therefore, predict that increasing the number of possible T1 identities, or target set, from 1 to 16 would lead to a larger AB. We were surprised to find that this manipulation of T1 difficulty had no influence on AB magnitude. In subsequent experiments, we found that AB magnitude interacts with T1 processing time only under certain circumstances. Specifically, when the T1 task was either well masked or had to be completed online, we found a reliable interaction between AB magnitude and the target set size. When neither of these conditions was fulfilled, there was no interaction between target set size and the AB. Previous research found that when the target set changes from trial to trial, trials with more possible targets elicited a larger AB. In the present study, the target set is held constant, reducing the demands on working memory. Nevertheless, AB magnitude still interacts with target set size, as long as the T1 task cannot be processed offline. Thus, the act of searching memory delays subsequent processing, even when the role of working memory has been minimized.  相似文献

Purpose

In the global economy, the need for understanding cross-cultural differences and the customer service-related processes involved in emotional labor is evident. The current study attempts to examine this issue by developing and testing hypotheses pertaining to cross-cultural differences between U.S. and Chinese service workers on the levels of display rule perceptions, emotion regulation, and burnout (i.e., emotional exhaustion, personal accomplishment, and depersonalization) as well as the relationships among these variables.

Design/Methodology/Approach

Data was collected from service workers in the U.S. (n = 280) and China (n = 231). We tested for measurement differences, mean differences, and differences in the relationships among emotional labor variables between the two samples using a variety of analyses.

Findings

It was found that the relatively robust sequence of display rules to surface acting to burnout was observed in a U.S. sample but was not observed in a Chinese sample, with some relationships being significantly weaker in the Chinese sample (e.g., surface acting to burnout dimensions) and others exhibiting relationships with the opposite sign (e.g., display rules were negatively related to surface acting in the Chinese sample).

Implications

The results of this study suggest that many of the relationships among emotional labor variables vary as a function of the cultural context under consideration.

Originality/Value

This is the first study to directly compare emotional labor across samples from Eastern and Western cultures. Additionally, this study begins to answer questions concerning why models of emotional labor generated in a Western culture may not apply in other cultures.  相似文献

Disasters and terrorism present significant and often overwhelming challenges for children and families worldwide. Individual, family, and social factors influence disaster reactions and the diverse ways in which children cope. This article links conceptualizations of stress and coping to empirical knowledge of children's disaster reactions, identifies limitations in our current understanding, and suggests areas for future study of disaster coping. Coping strategies, developmental trajectories influencing coping, and the interplay between parent and child coping represent critical areas for advancing the field and for informing programs and services that benefit children's preparedness and foster resilience in the face of mass trauma.  相似文献
