The present study examined the extent to which safety behaviors exacerbate symptoms of hypochondriasis (severe health anxiety). Participants were randomized into a safety behavior (n = 30) or control condition (n = 30). After a baseline period, participants in the safety behavior condition spent one week actively engaging in a clinically representative array of health-related safety behaviors on a daily basis, followed by a second week-long baseline period. Participants in the control condition monitored their normal use of safety behaviors. Compared to control participants, those in the safety behavior condition reported significantly greater increases in health anxiety, hypochondriacal beliefs, contamination fear, and avoidant responses to health-related behavioral tasks after the safety behavior manipulation. In contrast, general anxiety symptoms did not significantly differ between the two groups as a function of the manipulation. Mediational analyses were consistent with the hypothesis that changes in the frequency of health-related thoughts mediated the effects of the experimental manipulation on health anxiety. These findings suggest that safety behaviors are associated with increases in health anxiety, perhaps by fostering catastrophic thoughts about health. The implications of these findings for the conceptualization of hypochondriasis as an anxiety disorder are discussed. 相似文献

Signals during delays to reinforcement may lessen reductions in responding that typically occur when there is a delay between a response and its reinforcer. Sparse applied research has been devoted to understanding the conditions under which responding may be maintained when delays to reinforcement are introduced. We evaluated the extent to which providing signals during delay fading affected responding in the context of differential reinforcement of communication responses. Three individuals were exposed to gradually increasing signaled and unsignaled reinforcement delays in multiple‐schedule and/or withdrawal designs. Results for 2 of 3 participants suggested that (a) the presence of signals facilitated response maintenance under delayed reinforcement and (b) coordinated basic and applied research may advance both conceptual understanding and clinical outcomes of delayed reinforcement. 相似文献

The relationship between a reported history of trauma and dissociative symptoms has been explained in 2 conflicting ways. Pathological dissociation has been conceptualized as a response to antecedent traumatic stress and/or severe psychological adversity. Others have proposed that dissociation makes individuals prone to fantasy, thereby engendering confabulated memories of trauma. We examine data related to a series of 8 contrasting predictions based on the trauma model and the fantasy model of dissociation. In keeping with the trauma model, the relationship between trauma and dissociation was consistent and moderate in strength, and remained significant when objective measures of trauma were used. Dissociation was temporally related to trauma and trauma treatment, and was predictive of trauma history when fantasy proneness was controlled. Dissociation was not reliably associated with suggestibility, nor was there evidence for the fantasy model prediction of greater inaccuracy of recovered memory. Instead, dissociation was positively related to a history of trauma memory recovery and negatively related to the more general measures of narrative cohesion. Research also supports the trauma theory of dissociation as a regulatory response to fear or other extreme emotion with measurable biological correlates. We conclude, on the basis of evidence related to these 8 predictions, that there is strong empirical support for the hypothesis that trauma causes dissociation, and that dissociation remains related to trauma history when fantasy proneness is controlled. We find little support for the hypothesis that the dissociation-trauma relationship is due to fantasy proneness or confabulated memories of trauma. 相似文献

There is strong evidence that reactivation of a memory returns it to a labile state, initiating a restabilization process termed reconsolidation, which allows for updating of the memory. In this study we investigated reactivation-dependent updating using a new positively motivated spatial task in rodents that was designed specifically to model a human list-learning paradigm. On Day 1, rats were trained to run to three feeders (List 1) for rewards. On Day 2, rats were trained to run to three different feeders (List 2) in either the same (Reminder condition) or a different (No Reminder condition) experimental context than on Day 1. On Day 3, rats were cued to recall List 1. Rats in the Reminder condition made significantly more visits to List 2 feeders (intrusions) during List 1 recall than rats in the No Reminder condition, indicating that the reminder triggered reactivation and allowed integration of List 2 items into List 1. This reminder effect was selective for the reactivated List 1 memory, as no intrusions occurred when List 2 was recalled on Day 3. No intrusions occurred when retrieval took place in a different context from the one used at encoding, indicating that the expression of the updated memory is dependent upon the retrieval context. Finally, the level of intrusions was highest when retrieval took place immediately after List 2 learning, and generally declined when retrieval occurred 1-4 h later, indicating that the List 2 memory competed with short-term retrieval of List 1. These results demonstrate the dynamic nature of memory over time and the impact of environmental context at different stages of memory processing. 相似文献

Psychological interest in the impact of mental states on biological functioning is growing rapidly, driving a need for new methods for inducing mental states that last long enough, and are sufficiently impactful, to have significant effects on physical health. The many traditions of meditative practice are one potential pathway for studying mind‐body interactions. The purpose of this review is to introduce personality and social psychologists to the field of meditation research. Beginning with a brief introduction to meditation and the heterogeneity of meditative practices, we showcase research linking meditative practice to changes in immune and cardiovascular functioning and pain perception. We then discuss theoretical and empirical evidence that meditation works by inducing changes in psychological capacities such as emotion regulation and self‐regulation or through repeated induction of specific mental states such as love or meta‐cognitive awareness. At the frontier of the science of meditation is the need to empirically test whether meditation‐driven changes in cognitive and affective processes are the cause of improvements in physical health. Emerging challenges in meditation research include a need for large studies using randomized controlled and dual‐blind designs with active control groups and an increased focus on measuring mechanisms of action as well as outcomes. Meditation represents a potentially powerful tool for generating new knowledge of mind‐body interactions. 相似文献

We present a framework based on psycholinguistic theory to explain how individuals spell auditorily-presented information. We use the framework to predict and test how spelling-related characteristics of brand names and factors related to the context in which brand names are presented (e.g., spelling primes) will make the brands more or less memorable. Further, we reveal the process through which spelling-related linguistic variables influence brand recall: the dual-code (both written and auditory) that results from spelling a brand correctly leads to greater ability to later recall the brand. Our framework identifies two routes that interact when individuals have to transcribe a brand: the lexical (top-down) route and the sublexical (bottom-up) route. 相似文献

The current study investigated the effect of frequency of loss and awareness on the ability to make advantageous decisions in preschoolers using a child variant of the Iowa Gambling Task (Bechara, Damasio, Damasio, & Anderson, 1994). Preschoolers (N = 50) were randomly assigned to either a low loss frequency (0.1) or a high loss frequency (0.5) condition. The results suggested that increase in frequency of loss and higher awareness improved performance in the 4-year-olds. Finally, further analysis indicated that the effect of increased frequency on decision making was partially mediated by increased awareness of the game. The findings have implications for the integration of explicit and implicit processes in making adaptive choices. 相似文献

Clinical and counseling literature indicates that practicing psychologists often observe different mental health standards for women and men. Most of this research has examined mental health in terms of personality attributes, and as such there is a noticeable lack of research concerned with mentally healthybeliefs. The present research was concerned with the investigation of a possible gender bias in therapists' mental health standards, defined in terms of personal beliefs. For this purpose, the Irrational Beliefs Test (IBT; Jones, 1969) was completed three different times by a group of licensed psychologists in private practice, measuring their beliefs of how (1) a mentally healthy sex-unspecified adult, (2) a mentally healthy male adult, and (3) a mentally healthy female adult would respond to the IBT. The results indicated that both women and men therapists associated unique beliefs with women's and men's mental health.The late Dr. Frank B. Lambert studied the philosophical foundations of psychotherapy theory and was concerned about value issues in the practice of psychotherapy. He was pursuing his Ph.D. in counseling psychology at the time of his untimely death.Portions of these data were presented at the 1985 annual meeting of the American Psychological Association, Los Angeles, California. Graditude is extended to Lucia Gilbert and Mark R. Leary for their helpful comments on an earlier version of this article. 相似文献
