We tested the hypothesis that conceptual similarity promotes generalization of conditioned fear. Using a sensory preconditioning procedure, three groups of subjects learned an association between two cues that were conceptually similar, unrelated, or mismatched. Next, one of the cues was paired with a shock. The other cue was then reintroduced to test for fear generalization, as measured by the skin conductance response. Results showed enhanced fear generalization that correlated with trait anxiety levels in the group that learned an association between conceptually similar stimuli. These findings suggest that conceptual representations of conditional stimuli influence human fear learning processes. 相似文献

Cyber technology provides a new venue for the expression of aggression. However, whether cyber technology has produced a new group of peer aggressors or simply allowed aggressive peers new tools to victimize others is unclear. This study sampled 1,672 adolescents to assess their engagement in cyber aggression. Although "cyber," "overt," and "relational" represent distinct subtypes of aggressive behavior, our results indicate that adolescents' behaviors clustered according to their frequency-not type-of aggression. Thus cyber technology provides new tools for youth who already engage in aggressive behaviors in the physical world to victimize peers in cyberspace. 相似文献

Focusing on a sample of nurses, this investigation examined the relationships of daily task accomplishment satisfaction (for direct and indirect care tasks) with changes in positive and negative affect from preshift to postshift. Not accomplishing tasks to one's satisfaction was conceptualized as a daily workplace stressor that should increase daily negative affect and decrease daily positive affect from preshift to postshift. Further, because of the greater centrality of direct care nursing tasks to nursing work role identities (relative to indirect care tasks), we expected that task accomplishment satisfaction (or lack thereof) for these tasks would have stronger effects on changes in affect than would task accomplishment satisfaction for indirect care tasks. We also examined 2 person-level resources, collegial nurse-physician relations and psychological resilience, as moderators of the relationships among these daily variables, with the expectation that these resources would buffer the harmful effects of low task accomplishment satisfaction on nurse affect. Results supported almost all of the proposed effects, though the cross-level interactions were observed only for the effects of indirect care task accomplishment satisfaction on affect and not for direct care task accomplishment satisfaction on affect. 相似文献

The utility of the self-report Children’s Anxiety and Pain Scale Anxiety subscale (CAPS-A) in comparison to the widely used,
observer-rated Modified Yale Preoperative Anxiety Scale (mYPAS) in assessing anxiety in children undergoing day surgery procedures
was examined. The CAPS-A test-retest reliability, concurrent validity with the Modified Yale Preoperative Anxiety Scale (mYPAS),
and sensitivity to expected increases in anxiety at stressful times during the preoperative period were examined. Levels of
observer-rated (mYPAS) and self-reported anxiety (CAPS-A) were obtained from 61 children (3 to 6 years) undergoing day surgery
procedures. The CAPS-A demonstrated adequate test-retest reliability. Concurrent validity between the CAPS-A and mYPAS scores
was poor. The CAPS-A failed to show sensitivity to the expected increases in anxiety at stressful time-points. Thus, an alternative
scoring strategy for the CAPS-A was proposed (i.e., child’s refusal to point was scored as high anxiety). Post-hoc analyses
demonstrated good concurrent and adequate convergent validity with the alternative scoring strategy. 相似文献

Making decisions with an, often significant, element of risk seems to be an integral part of many of the projects of the diverse profession of engineering. Whether it be decisions about the design of products, manufacturing processes, public works, or developing technological solutions to environmental, social and global problems, risk taking seems inherent to the profession. Despite this, little attention has been paid to the topic and specifically to how our understanding of engineering as a distinctive profession might affect how we should make decisions under risk. This paper seeks to remedy this, firstly by offering a nuanced account of risk and then by considering how specific claims about our understanding of engineering as a social profession, with corresponding social values and obligations, should inform how we make decisions about risk in this context. 相似文献

Research supports the efficacy of both cognitive dissonance (CD) and healthy weight (HW) eating disorders prevention, and indicates that CD can be delivered by peer-facilitators, which facilitates dissemination. This study investigated if peer-facilitators can deliver HW when it is modified for their use and extended follow-up of peer-facilitated CD as compared to previous trials. Based on pilot data, we modified HW (MHW) to facilitate peer delivery, elaborate benefits of the healthy-ideal, and place greater emphasis on consuming nutrient dense foods. Female sorority members (N = 106) were randomized to either two 2-h sessions of CD or MHW. Participants completed assessment pre- and post-intervention, and at 8-week, 8-month, and 14-month follow-up. Consistent with hypotheses, CD decreased negative affect, thin-ideal internalization, and bulimic pathology to a greater degree post-intervention. Both CD and MHW reduced negative affect, internalization, body dissatisfaction, dietary restraint, and bulimic pathology at 14 months. 相似文献

Research and treatment have traditionally adopted a 'disorder-focused' approach by targeting one specific disorder, aiming to understanding its cause, maintenance and treatment. The aim of the present study was to contribute to the burgeoning interest in examining common, or 'transdiagnostic,' processes across disorders. Three candidate transdiagnostic processes involved in emotion regulation - rumination, worry, and automatic negative thoughts - were examined in euthymic bipolar I disorder (n=21) and insomnia (n=19), and a non-clinical control group (n=20). Rumination and worry were endorsed to a larger degree by the bipolar and insomnia groups compared to the control group. However, while the bipolar group had more negative automatic thoughts than the control group, there were no significant differences in negative automatic thoughts between the bipolar and insomnia groups or the insomnia and control groups. These results suggested that rumination and worry, but not negative automatic thoughts, might be common across bipolar disorder and insomnia. However, these findings no longer remained significant when current symptoms of anxiety and depression were controlled for. Prospective and experimental studies are needed to test the extent to which these processes contribute to the etiology or maintenance of insomnia and bipolar disorder. 相似文献

In Study 1, 6-week- and 3-month-old infants gazed more to an adult when she alternated attention between an object and the infant versus when attention was directed only to the object. In Study 2, 6-week-olds did not discriminate between triadic situations with face-to-face interaction controlled. 相似文献

The Rev. is a BASIC computer program for IBM-PC-compatible systems that provides Bayesian estimates of “true” scores from multiple scores measuring the same construct. Psychological reports often include test scores from earlier evaluations without objectively incorporating them into current findings. Using Thorndike’s formulas for objectively combining test scores while providing estimates with reduced standard errors, the Rev. is an interactive program that facilitates test interpretation by combining information from many test administrations. The user provides four easily obtainable pieces of information for each test administration. The output includes an estimated “true” score and the standard error of the estimate. 相似文献
