We review positron emission tomography (PET) studies whose results converge on the hemispheric encoding/retrieval asymmetry (HERA) model of the involvement of prefrontal cortical regions in the processes of human memory. The model holds that the left prefrontal cortex is differentially more involved in retrieval of information from semantic memory, and in simultaneously encoding novel aspects of the retrieved information into episodic memory, than is the right prefrontal cortex. The right prefrontal cortex, on the other hand, is differentially more involved in episodic memory retrieval than is the left prefrontal cortex. This general pattern holds for different kinds of information (e.g., verbal materials, pictures, faces) and a variety of conditions of encoding and retrieval. 相似文献

Inner city, psychiatrically hospitalized adolescents are accessible to group therapy intervention. We developed a unique approach combining Slavson's theories with principles of family treatment and psychoanalytic theory. The group was conceptualized as a corrective family experience with the therapists functioning as model parents. Our model relies on a four-phase process, which is discussed. 相似文献

Previous work has shown that mice missing the α-isoform of calcium–calmodulin-dependent protein kinase II (α-CaMKII) have a deficiency in CA1 hippocampal long-term potentiation (LTP). Follow-up studies on subsequent generations of these mutant mice in a novel inbred background by our laboratories have shown that whereas a deficiency in CA1 LTP is still present in α-CaMKII mutant mice, it is different both quantitatively and qualitatively from the deficiency first described. Mice of a mixed 129SvOla/SvJ;BALB/c;C57Bl/6 background derived from brother/sister mating of the α-CaMKII mutant line through multiple generations (>10) were produced by use of in vitro fertilization. Although LTP at 60 min post-tetanus was clearly deficient in these (−/−) α-CaMKII mice (42.6%, n=33) compared with (+/+) α-CaMKII control animals (81.7%, n=17), α-CaMKII mutant mice did show a significant level of LTP. The amount of LTP observed in α-CaMKII mutants was normally distributed, blocked by APV (2.7%, n=8), and did not correlate with age. Although this supports a role for α-CaMKII in CA1 LTP, it also suggests that a form of α-CaMKII-independent LTP is present in mice that could be dependent on another kinase, such as the β-isoform of CaMKII. A significant difference in input/output curves was also observed between (−/−) α-CaMKII and (+/+) α-CaMKII animals, suggesting that differences in synaptic transmission may be contributing to the LTP deficit in mutant mice. However, tetani of increasing frequency (50, 100, and 200 Hz) did not reveal a higher threshold for potentiation in (−/−) α-CaMKII mice compared with (+/+) α-CaMKII controls. 相似文献

Attention shifts produce spatial stimulus codes 总被引:3,自引:0,他引:3
Summary In the Simon task the spatial position of the stimulus, though task irrelevant, influences speed of response. We (Umiltà & Nicoletti, 1992) proposed that the orienting of attention to the imperative stimulus produces a Stroop-like interference. This paper reports the results of three experiments that provide empirical support for two predictions of this hypothesis. One is that the stimulus spatial code is formed with relation to the position to which attention is directed. The other prediction is that the Simon effect is obtained on condition that attention can orient to the stimulus.Some of the results of Experiments 1 and 2 were reported briefly in Umiltà and Nicoletti (1992) 相似文献

The role of vulnerable environments in support for homegrown terrorism: Fieldwork using the 3N model
Roberto M. Lobato Manuel Moyano Jocelyn J. Blanger Humberto M. Trujillo 《Aggressive behavior》2021,47(1):50-57
The 3N model of radicalization proposes that violent radicalization is the result of the contribution of needs, networks, and narratives. Although research has mainly been supportive of this perspective, a substantial amount of ground remains uncovered regarding the network component of the model. Within this framework, we examine why individuals living in certain social environments tend to harbor more positive attitudes toward homegrown terrorism than others. Building on prior research, we hypothesized that individuals living in social environments known to be vulnerable (vs. less vulnerable) are more likely to experience a sense of significance loss (i.e., lack of social integration, perceived conflicts between religious groups), find solace in religious social networks (i.e., mosques), and thus adhere to radical narratives (i.e., legitimization of terrorism). A study with 365 young Muslims from different cities in Spain (Almería, Barcelona, Ceuta, and Melilla)supported these predictions. Theoretical and practical implications for the study of violent extremism are discussed. 相似文献

Across the globe, collective action has been a notable driver of social change. Previous research has identified numerous psychological antecedents of collective action participation, such as group efficacy. The mobilizing influence of social norms, however, has been comparatively neglected. Among a nationally representative Chilean sample (N = 3328), a three-wave longitudinal study tested the relationship between the perceived frequency of family and friends' participation in social movements (norms of close social networks) and change in the frequency of participants' own engagement over time. Perceived efficacy of social movements to facilitate social change was tested as a mediator of this relationship. A fully constrained bidirectional cross-lagged panel model revealed that norms of close social networks significantly predicted social-movement participation over time. This longitudinal relationship was also significantly mediated by group efficacy. Direct reverse paths were also observed, with social-movement participation predicting norms of close social networks over time. Considering low degrees of political participation often seen in societies, these results suggest that utilizing the normative context to promote participation in social movements may prove fruitful in mobilizing the drive for social change. 相似文献
