Loneliness is a psychological construct that has been reported in a variety of populations and associated with a number of other negative psychological problems. This study was an examination of coefficient alpha of a prominent measure of loneliness: the University of California, Los Angeles (UCLA) Loneliness Scale (Russell, Peplau, & Cutrona, 1980; Russell, 1996). We utilized reliability generalization to provide an aggregate estimate of the reliability of the scale over time and in a variety of populations as well as to assess and identify sampling and demographic characteristics associated with variability in coefficient alpha. Of the 213 studies examined, 80 had reported alpha estimates, and we used them in this analysis. We discuss conditions associated with variability in coefficient alpha along with pertinent implications for practice and future research. 相似文献

In two experiments, participants were presented with successive presentations of animal names (e.g., GORILLA, WHALE)--a prime display followed by a probe display. In response to each display, participants judged either the typical habitat or the relative size of those animals, repeating the same task in response to both displays on half of the experimental trials and switching from one task to the other on the other half of trials. Our results demonstrate that switch costs can be reduced when either the probe's identity or its location is predictive of a change in task. This result establishes that the presentation of a stimulus can serve as a rapid cue for facilitating a switch in task, independent of processes occurring both at the time of the prime task and during the intervening period between the prime and probe tasks. We discuss the implications of these results for prevailing explanations of task switching costs. 相似文献

This preliminary study compared brief (1 s) and extended (4 s) wait-time on response opportunities, academic responses, accuracy,
and disruptive behavior of two children with challenging behavior during small group instruction. Brief wait-time increased
children’s response opportunities, academic responses, and accuracy in comparison to extended wait-time. Though variable,
brief wait-time also decreased children’s disruptive behavior. Findings differ from previous research, which found performance
improvements with extended wait-time for children with moderate to profound cognitive disabilities. Limitations of the study
and future research suggestions are discussed. 相似文献

Posttraumatic stress related to the September 11, 2001 terrorist attacks and general psychological distress were examined in six cohorts of college students (N=5412) enrolled at an American public university between Spring 2000 and Fall 2002 some 2,500 miles from New York. Consistent with data from Schuster et al.'s (2001) national survey, which used a very low threshold criterion, our findings revealed that 44% of women and 32% of men experienced at least one symptom of posttraumatic stress 6-17 days after the attacks. In contrast to these results, depression levels showed only small differences, and self-esteem and trait anxiety showed no changes. Findings indicate that 9/11-related stress responses among distant witnesses were very mild, transitory and focused in scope, suggesting resilience with respect to broader psychological and psychopathological reactions. Findings are discussed with respect to the role of physical and psychological proximity on the reactions to traumatic events in the general population. 相似文献

Type A personality has been conceptualized in part as high need for achievement combined with aggression, hostility, and self-esteem issues. In teams of undergraduate business students, high levels of Type A personality significantly correlated with high levels of depression and high levels of social monitoring; and negatively correlated with social desirability, communality, and individual performance across time. In team settings, the more Type A's were balanced in a team with low Type A's, the more there was team commitment and the more team synergy behaviors; while if teams had a greater number of Type A's, there was more individualistic behavior, and team project scores were lower. 相似文献

Due to the intriguing nature of the psychopathy construct, it is not surprising that psychopathic characters would appear
in popular culture. At times, media portrayals of psychopathic personality are consistent with scholarly research, others
times they are not. In the case of Hannibal Lecter, the psychopathic killer was framed as an individual with superior intelligence—an
omnibus intelligence that enhanced his ability to manipulative and victimize others. Contrary to this popular conception and
based on data from 840 cases selected from the MacArthur Violence Risk Assessment Study, ordinary least squares and ordered
logistic regression models showed inverse relationships between verbal intelligence and psychopathy for eight of twelve items
of the disorder in this exploratory study. Due to the uniqueness of the MacArthur sample and concern about generalizeability,
further research on verbal intelligence and psychopathy is recommended. 相似文献

Betrayal Trauma Theory (BTT) holds that certain traumas, such as incest, should be uniquely categorized as betrayal trauma: a subcategory of trauma in which the violation of trust, within a close relationship, occurs in the context of a traumatic event. According to BTT, betrayal trauma results in either partial or complete traumatic amnesia because repression is adaptive when a victim depends on a perpetrator for physical or emotional needs. In a test of BTT, undergraduates screened for betrayal and non‐betrayal trauma histories provided detailed accounts of these events. In order to account for threats to internal validity that are often overlooked by traumatic amnesia researchers, we also assessed factors known to compromise narrative detail. Consistent with BTT predictions, more betrayal was associated with less detailed trauma narratives. However, this relationship was no longer significant after controlling for survivor age, avoidance symptoms, gender and purposeful omission of detail. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献
