Correlates of intellectual ability with morphology of the hippocampus and amygdala in healthy adults 总被引:1,自引:0,他引:1
Several prior imaging studies of healthy adults have correlated volumes of the hippocampus and amygdala with measures of general intelligence (IQ), with variable results. In this study, we assessed correlations between volumes of the hippocampus and amygdala and full-scale IQ scores (FSIQ) using a method of image analysis that permits detailed regional mapping of this correlation throughout the surface contour of these brain structures. We delineated the hippocampus and amygdala in high-resolution magnetic resonance images of the brain from 34 healthy individuals. We then correlated FSIQ with overall volumes and with the surface morphologies of each of these structures. Hippocampus volumes correlated significantly and inversely with FSIQ independently of gender, age, socioeconomic status, and whole brain volume. Left and right hippocampus volumes correlated respectively with verbal and performance IQ subscales. Higher IQs were significantly associated with large inward deformations of the surface of the anterior hippocampus bilaterally. These findings suggest that a smaller anterior hippocampus contributes to an increased efficiency of neural processing that subserves overall intelligence. 相似文献

This article illustrates ideas for bridging science and practice generated during the Division of Violence Prevention's (DVP) dissemination/implementation planning process. The difficulty of moving what is known about what works into broader use is near universal, and this planning process pushed us to look beyond the common explanations (e.g., providers were resistant/unwilling to change practice) and think about the multiple layers and systems involved. As part of this planning process, the Interactive Systems Framework for Dissemination and Implementation (ISF) was developed and then applied to the fields of child maltreatment and youth violence prevention. Challenges for each of the three systems in the ISF are discussed as well as and action and research ideas to address the challenges. Also described are actions taken by DVP in response to the planning process to illustrate how a funder can use the ISF to bridge science and practice. 相似文献

This research investigated demographic and attitudinal- psychological predictors of verdict and amount of punitive damages awarded in high-stakes civil litigation. Four hundred and forty-six surrogate jurors, selected to be representative of actual jurors, were exposed to realistic case presentations in insurance, tobacco, and pharmaceutical cases that were about to go to trial. Hierarchical regression revealed that perceptions of the existence of a litigation crisis predicted verdict in the tobacco and pharmaceutical cases after controlling for all other variables. Demographic variables predicted verdict and punitive damage awards only modestly and in different ways in the three cases. Need for cognition, strength of will and rationality, and a perception that there is a litigation crisis predicted the amount of punitive damages awarded in the tobacco case. Litigation crisis also predicted the amount of punitive damages awarded in the pharmaceutical case. Implications for jury selection are discussed. 相似文献

Today, internet-based technologies are used at all levels of psychosocial services. Current psychotherapeutic applications concentrate on the implementation of traditional approaches in the internet. Self-help programs are posted onto the net, therapies are conducted via e-mail and groups meet in virtual chat rooms. If one looks at the development of the web over the last 2 years, it becomes clear that the substantial growth and popularity of this medium is due to internet platforms where contents and knowledge can be developed in collaborative environments and experiences can be shared with other users. The present paper addresses this development. On the basis of our example it is discussed how collaborative elements can be integrated into a psychotherapeutic application. 相似文献

Seven hundred and thirty-two parents reported when and how their infants learned to climb stairs. Children typically mastered stair ascent (mean age=10.97 months) several months after crawling onset and several weeks prior to descent (mean age=12.53 months). Most infants (94%) crawled upstairs the first time they ascended independently. Most infants (76%) turned around and backed at initial descent. Other descent strategies included scooting down sitting, walking, and sliding down face first. Children with stairs in their home were more likely to learn to ascend stairs at a younger age, devise backing as a descent strategy, and be explicitly taught to descend by their parents than children without stairs in their home. However, all infants learned to descend stairs at the same age, regardless of the presence of stairs in their home. Parents' teaching strategies and infants' access to stairs worked together to constrain development and to influence the acquisition of stair climbing milestones. 相似文献

This study evaluated the serial position curve based on free recall of spatial position sequences. To evaluate the memory processes underlying spatial recall, some manipulations were introduced by varying the length of spatial sequences (Exp. 1) and modifying the presentation rate of individual positions (Exp. 2). A primacy effect emerged for all sequence lengths, while a recency effect was evident only in the longer sequences. Moreover, slowing the presentation rate increased the magnitude of the primacy effect and abolished the recency effect. The main novelty of the present results is represented by the finding that better recall of early items in a sequence of spatial positions does not depend on the task requirement of an ordered recall but it can also be observed in a free recall paradigm. 相似文献

In the present study, we used the Deese/Roediger-McDermott paradigm to analyze the relationship between theme identifiability
of word lists and false memories in adults and children. We conducted two normative studies to determine the identifiability
levels for critical unpresented words in 40 associative lists in adults and in 16 associative lists in children. Then, in
three experiments, false memories for critical words that were either easy or hard to identify were analyzed in adults and
in children 4–5 years old and 11–12 years old. Opposite results were found for adults and children. Lists with highly identifiable
critical words produced fewer false memories for adults but more false memories for children. These results suggest that,
if they can identify critical words, adults use an identify-to-reject strategy to edit out false memories, whereas, in children,
theme identification does not lead to the use of such a monitoring strategy. 相似文献

Drawing on interviews with 90 young people who have become Witches, we explore the visual media's influence on identity formation and maintenance. Witchcraft is a late modern religion that is highly individualistic and many young people report they have become a Witch without any interaction with other Witches. The rapid growth of interest in this religion among the young since The Craft was first shown provides an important example of the mass media's role in formation of contemporary religious identity. We argue that representations of Witchcraft in the visual mass media (along with other cultural trends such as environmentalism, feminism, and individualism) and cultural resources such as books, Internet sites, and magazines provide a mediated form of social interaction that sustains the plausibility of Witchcraft as a religion. It also helps the young to develop and legitimate their beliefs and practices and develop their Witchcraft persona. 相似文献

The current study seeks to explore the effect of an academic course on sense of coherence (SOC) and transitory mood states. Moreover, the causal relationships between SOC and transitory mood states was evaluated. Second-year pharmacology students completed pencil-and-paper questionnaires at the beginning of the semester and 3-1/2 months later. The study group ( n = 37) participated in an academic course developed to teach cognitive behavior concept and practice, whereas the control group ( n = 43) had additional sessions of laboratory work. SOC increased significantly after the course while tension–anxiety and confusion decreased significantly. Structural equation analyses in the study group suggested that SOC was modified by confusion and perceived stress. No such pattern was observed in the control group. 相似文献
