Insulin has been shown to impact on learning and memory in both humans and animals, but the downstream signaling mechanisms involved are poorly characterized. Insulin receptor substrate-2 (Irs2) is an adaptor protein that couples activation of insulin- and insulin-like growth factor-1 receptors to downstream signaling pathways. Here, we have deleted Irs2, either in the whole brain or selectively in the forebrain, using the nestin Cre- or D6 Cre-deleter mouse lines, respectively. We show that brain- and forebrain-specific Irs2 knockout mice have enhanced hippocampal spatial reference memory. Furthermore, NesCreIrs2KO mice have enhanced spatial working memory and contextual- and cued-fear memory. Deletion of Irs2 in the brain also increases PSD-95 expression and the density of dendritic spines in hippocampal area CA1, possibly reflecting an increase in the number of excitatory synapses per neuron in the hippocampus that can become activated during memory formation. This increase in activated excitatory synapses might underlie the improved hippocampal memory formation observed in NesCreIrs2KO mice. Overall, these results suggest that Irs2 acts as a negative regulator on memory formation by restricting dendritic spine generation. 相似文献

Large numbers of therapists worldwide wish to receive training in how to deliver psychological treatments. Current methods of training are poorly suited to this task as they are costly and require scarce expertise. New forms of training therefore need to be developed that are more cost-effective and scalable. Internet-based methods might fulfil these requirements whilst having the added advantage of being able to provide trainees with extensive exposure to the treatment as practised. New strategies and procedures for evaluating training outcome are also required. These need to be capable of assessing the therapist's knowledge of the treatment and its use, as well as the therapist's ability to apply this knowledge in clinical practice. Standardised role play-based techniques might be of value in this regard. 相似文献

This paper integrates Zen and psychoanalytic concepts; introduces the Zen concept of total exertion; elaborates the profound
implications that the notion of total exertion has for the psychoanalytic encounter and the psychotherapist’s capacity for
maintaining an optimal attentional stance; addresses anxiety-driven interferences to both the psychoanalytic process and deepened
Zen practice. Clinical vignettes, personal experiences, poetry and psychoanalytic theory serve to demonstrate the abstract
aspects of the discussion. 相似文献

Increased vigilance to threat-related stimuli is thought to be a core cognitive feature of anxiety. We sought to investigate the cognitive impact of experimentally induced anxiety, by means of a 7.5% CO(2) challenge, which acts as an unconditioned anxiogenic stimulus, on attentional bias for positive and negative facial cues of emotional expression in the dot-probe task. In two experiments we found robust physiological and subjective effects of the CO(2) inhalation consistent with the claim that the procedure reliably induces anxiety. Data from the dot-probe task demonstrated an attentional bias to emotional facial expressions compared with neutral faces regardless of valence (happy, angry, and fearful). These attentional effects, however, were entirely inconsistent in terms of their relationship with induced anxiety. We conclude that the previously reported poor reliability of this task is the most parsimonious explanation for our conflicting findings and that future research should develop a more reliable paradigm for measuring attentional bias in this field. 相似文献

To meet a diagnosis for a particular personality disorder (PD), among other requirements, a person must exhibit a specified minimum number of the features outlined for that PD, otherwise referred to as the diagnostic threshold. Despite many years of research on the DSM PDs, there is little empirical basis for the chosen thresholds. The present study used mechanisms of item response theory (IRT) to link the diagnostic thresholds of six PDs to their corresponding level of latent PD pathology. Consistent with our hypothesis, analyses of the data from 41,227 participants revealed that PD diagnostic thresholds corresponded to a wide range of latent pathology. For example, the diagnostic threshold for schizoid PD corresponded to 1.54 SDs of pathology whereas the threshold for dependent PD corresponded to 2.72 SDs of pathology. The current analyses have demonstrated for the first time that the latent pathology associated with each PD threshold varies widely, and thus has quantified what others accurately have speculated. Implications and considerations for the future directions of PD classification are discussed. 相似文献

We report two studies that investigate single‐response situational judgment tests (SJTs) as measures of job knowledge. Study 1 examines relationships between job knowledge measured by a single‐response SJT, personality, and performance for museum tour guides. Study 2 extends Study 1's findings with a sample of volunteers using a single‐response SJT about volunteerism. In both studies, personality was related to knowledge, and knowledge predicted performance. In Study 2, knowledge accounted for incremental variance in performance beyond personality, but personality added no incremental variance beyond knowledge. Results suggest that knowledge of effective behavior and knowledge of ineffective behavior are separate constructs. These studies demonstrate the validity of single‐response SJTs and provide evidence that knowing what to do and what not to do are separate domains. 相似文献

In recent years, organizational socialization research has focused increasingly on the tactics that newcomers use to guide their own adjustment. Various subsets of adjustment tactics have been studied, with minimal rationale as to why newcomers would use different behaviors. We present a typology for newcomer adjustment tactics, comprising opportunistic, self‐determined, and shared behaviors, to categorize and integrate all newcomer adjustment tactics identified to date. Next, we propose a model in which tactic use is a function of cost–benefit analyses – on performance, ego, and social dimensions – influenced by individual and contextual factors. This integrates the diverse literatures on socialization, adjustment, information seeking, feedback seeking, and coping. Integrating our initial tactics categorization and the cost–benefit model, we present a robust set of propositions that inform newcomers' perceptions and use of adjustment tactics. We conclude by presenting theoretical and practical implications for newcomer adjustment. 相似文献
