In this study, the authors examined the relationships among procrastination, efficacy expectations, anxiety, gender, and age for 141 university students. Participants were asked to think about a major project and to rate their efficacy regarding the skills needed to accomplish the project. Bivariate correlations showed that efficacy expectations and anxiety had significant, individual relationships with procrastination. When these variables were entered into a regression model, only cumulative efficacy strength was a significant predictor of procrastination. Implications for practice and research suggestions are discussed.  相似文献

One perspective from which to view Christian‐Muslim relations is to analyse beliefs and practices shared by Christians and Muslims in a particular culture. This paper analyses contractual prayer as practised by many adherents of the four main religious sects of Lebanon: Sunni and Shicfa Muslims and Maronite and Orthodox Christians. Contractual prayer (nidr in colloquial Arabic) is a prayer of petition addressed to the supernatural in which the petitioner couples a request with a conditional promise. Many similarities in the practice are attributable to inherent limitations of this type of prayer, to common human concerns that are expressed in the requests made, and to shared perspectives on gender and other cultural norms. Significant sect‐specific differences are most apparent regarding the supernatural being to whom the request is addressed, the nature of the conditional promise, and the manner and extent to which the practice is institutionalized.  相似文献

Results from research with the flanker task have been used to argue both that flankers are identified without attention and that flanker identificatin requires attention. In three experiments, we addressed this issue by examining flanker recall. In Experiment 1, we manipulated flanker redundancy, a variable that could influence attention to the flankers, in order to determine whether it affected the magnitude of the flanker effect, the magnitude of flanker recall, or both. Redundancy did not influence the flanker effect, and recall was high in both conditions, suggesting that the flankers were attended. The recall results contradicted those of Miller (1987), the only other study that we could find in which flanker recall was used. In Experiments 2 and 3, we examined differences between Miller’s procedure and ours. Although flanker recall was lower when open-ended rather than forced recall was used and when the flanker task was made more complicated, flanker recall remained well above chance in all conditions. The data strongly suggest that in the typical correlated flanker task there is a failure of selective attention at some point during processing such that flankers receive attentional processing.  相似文献

Children's comprehension of the universal quantifiers all and each was explored in a series of experiments using a picture selection task. The first experiment examined children's ability to restrict a quantifier to the noun phrase it modifies. The second and third experiments examined children's ability to associate collective, distributive, and exhaustive representations with sentences containing universal quantifiers. The collective representation corresponds to the “group” meaning (for All the flowers are in a vase all of the flowers are in the same vase). The distributive representation implies a pairing (e.g., each flower paired with a vase for Each flower is in a vase). The exhaustive representation exhausts both sets (e.g., for The flowers are in the vases all the flowers are in vases and all the vases have flowers in them). Four- to 10-year-old children had little difficulty restricting the quantifier all to the noun it modified in a task which required them to attend to the group feature of all. In contrast, only 9- and 10-year-olds were able to solve the task when the quantifier was each and the pictures showed entities in partial one-to-one correspondence. Children showed a preference for associating collective pictures with sentences containing all and distributive pictures with sentences containing each. The results suggest that between the ages of 5 and 10 years, children's semantic representations undergo less radical changes than others have proposed. Instead, developmental change may occur gradually as children acquire linguistic cues which map onto existing semantic representations.  相似文献

The purpose of this study was to teach contextually appropriate affective behavior to 4 youths with autism. Treatment consisted of modeling, prompting, and reinforcement introduced in a multiple baseline design across response categories of affective behavior. During treatment, verbal praise and tokens were delivered contingent on appropriate affective responding during training trials. Modeling and verbal prompting were used as correction procedures. Each youth received treatment in either three or four response categories. Treatment systematically increased responding within the response categories for all 4 participants, with effects being specific to the affective response categories under treatment. Treatment effects occurred across untrained scenarios, therapists, time, and settings, suggesting that generalization had occurred.  相似文献

A Sternberg memory search task was administered under placebo and methylphenidate to 42 children with cross-situational attention deficit disorder (ADD), 31 children with cross-situational ADD plus oppositional features, and 25 patients with marginal ADD. Overall, stimulant medication enhanced accuracy and speed. In addition, patients reacted faster on correct responses not preceded by an error than on errors (especially false alarms) or on correct responses following an error. The slowness during error reactions may reflect decreased confidence or confusion during stimulus classification. This uncertainty may also lead subjects to respond with greater caution, hence more slowly, on correct responses following errors. Notably, methylphenidate increased the slowing of reactions on error trials as well as on correct reactions following an error. Stimulant medication may augment subjects' persistence when they are uncertain or confused, thereby heightening caution and promoting accuracy on succeeding trials. Consistent with previous reports of the generality of enhancement of performance by stimulant medication, the impact of methylphenidate was comparable for the three subtypes of ADD studied.Jaine Strauss is at Macalester College.This research was supported by National Institute of Mental Health Grants MH32103 and MH38118.

The authors review outcome studies in the treatment of panic disorder without agoraphobia for an adult population. Empirical evidence is presented to support the efficacy of psychopharmacological and cognitive-behavioral interventions. In addition, this article can serve as the basis for the development of emerging standards of cure for the diagnosis and treatment of panic disorder.  相似文献

Twenty-nine college women evidencing low body esteem, repeated dieting efforts, and other dysfunctional eating behaviors or attitudes were randomly assigned to group treatment or control conditions. At posttest and follow-up, participants who received the intervention reported significantly improved levels of self-esteem and body satisfaction, as well as reductions in their reliance on potentially dangerous methods of weight management compared with controls. They also reported fewer fears of negative evaluation by others and endorsed fewer stereotypes about thinness and attractiveness. Finally, participants in the treatment condition showed significantly reduced levels of perfectionism at posttest, but this change was not maintained at follow-up. Clinical implications and research recommendations are discussed.  相似文献

Psychophysiological reactivity has been well documented in WWII, Korean Conflict, and Vietnam veterans with posttraumatic stress disorder (PTSD). In addition, these individuals have demonstrated cognitive impairments within the domains of attention, concentration, new learning, and memory. However, there has been no research examining the impact of physiological arousal on attention in individuals with PTSD. This study documents the level of physiological arousal and associated disruption of attentional abilities in 28 Persian Gulf War veterans (18 without PTSD or other psychopathology and 10 with PTSD). This population represents a group of combat trauma victims who experienced a relatively acute onset of PTSD, thus providing a unique opportunity to compare prior psychophysiological and cognitive results with a group of veterans who manifested a recent onset of PTSD. Results indicated relatively comparable psychophysiological reactivity and arousal between Persian Gulf War veterans with PTSD and Persian Gulf War veterans without PTSD. Furthermore, attentional processes of veterans with PTSD were not more disrupted than in comparison soldiers. Results suggest that the intensity and chronicity of the disorder may impact physiological arousal and disruption of cognitive functioning. Following Persian Gulf War veterans with PTSD over time may reveal that psychophysiological arousal becomes more pronounced with chronicity, perhaps as memory networks become strengthened and/or neuroendocrine systems become increasingly disrupted.  相似文献

This article extends the organizational entry and newcomer stress literature by focusing on the importance of building a self-reliant workforce. It posits that newcomer socialization now and in the future requires building a workforce of self-reliant managers and employees who can function effectively in a dynamic, global workplace. This article suggests that socializing workers to be self-reliant helps employees and organizations to thrive in the uncertain economic environment that is the determining factor in the success of today's organizations. It further contends that by reducing ambiguity and increasing employability, employees are likely to suffer less distress and organizations are less likely to pay the price for distressed employees.  相似文献
