A 2003 comparative study on learning environments at two military officer training sites was replicated using different methodology. Satisfaction with learning environment and with administrative inprocessing was higher at Fort Leavenworth than at Fort Dix. Most students expressed a preference for Fort Leavenworth. Satisfaction with institutional support and educational facilities appears to influence perceived satisfaction with a learning environment and with preference for training sites among senior military officers.  相似文献

In 3 experiments, rats were required to find a submerged platform located in 1 corner of an arena that had 2 long and 2 short sides; they were then trained to find the platform in a new arena that also had 2 long and 2 short sides but a different overall shape. The platform in the new arena was easier to find if it was in a corner that was geometrically equivalent, rather than the mirror image, of the corner where it had previously been located. The final experiment revealed that hippocampal lesions impaired rats' ability to find the platform in these arenas. The results suggest that rats did not use the overall shape of the arena to locate the platform but relied on more local cues and that the hippocampus plays a role in navigation based on these cues.  相似文献

Post-modern psychology embodies two core themes, the social mind and the narrative self. Whereas the social-mind thesis seems diametrically opposed to Jung's position regarding human nature, the narrative-self thesis is associated with research and theorizing about personal myth and mythmaking in ways that could make contact with Jung's concerns. Jung's view is examined here with particular attention to McAdams' theory of narrative identity. It is suggested that the ostensible differences between Jung and post-modern psychology might reflect divergent interests, rather than necessarily irreconcilable worldviews.  相似文献

A novel negative priming (NP) effect is reported in which serial recall for a sequence of visually presented digits was poorer if the same sequence was presented as an irrelevant auditory sequence on the previous trial (Experiments 1 and 2). The effect was enhanced when attention was divided between the to-be-repeated auditory sequence and the concurrent to-be-remembered (TBR) sequence (Experiment 3). When the TBR sequences were also presented auditorily, NP arose only when the repeated TBR sequence was in the same voice as the previous irrelevant sequence; a voice mismatch produced positive priming (Experiment 4). The results suggest that the order of auditory events is registered preattentively and that inhibition may be applied to the acoustic transitions between irrelevant events.  相似文献

Recency effects (REs) have been well established in memory and probability learning paradigms but have received little attention in category earning research. Extant categorization models predict REs to be unaffected by learning, whereas a functional interpretation of REs, suggested by results in other domains, predicts that people are able to learn sequential dependencies and incorporate this information into their responses. These contrasting predictions were tested in 2 experiments involving a classification task in which outcome sequences were autocorrelated. Experiment 1 showed that reliance on recent outcomes adapts to the structure of the task, in contrast to models' predictions. Experiment 2 provided constraints on how sequential information is learned and suggested possible extensions to current models to account for this learning.  相似文献

The impact of Hurricane Andrew on 212 African American, Caucasian, and Hispanic elementary and middle school children was examined at 6 months postdisaster. Using self-report instruments, this case study examined the predictive utility of several hypothesized mediators of children's reactions to disaster. Results showed higher levels of intrusive symptomatology for girls and for elementary school children as compared with their middle school counterparts. No differences were found with reference to race. The lack of findings concerning race is addressed, as well as implications for future studies.  相似文献

Biomedicine is a global enterprise constructed upon the belief in the universality of scientific truths. However, despite huge scientific advances over recent decades it has not been able to formulate a specific and universal definition of death: In fact, in its attempt to redefine death, the concept of death appears to have become immersed in ever increasing vagueness and ambiguity. Even more worrisome is that bioethics, in the form of principlism, is also endeavouring to become a global enterprise by claiming neutrality. It appears that the discourse within both disciplines have similarly manipulated the boundaries of death to include the “dying”. This paper argues that the redefinition of death debate in biomedicine reveals a concept of personhood which is profoundly western in origin and which is in accordance to the concept adhered to within principlism. Biomedicine and bioethics do not appear to acknowledge the limitations of their own world view and hence lack an understanding of their applicability and appropriateness in diverse social and cultural contexts; a situation which adds credence to claims as to the hegemonic and imperialistic nature of all such global enterprises. Ms. Jones is an intensive care clinical nursing specialist. Dr. Kessel is a public health physician and medical ethicist.  相似文献
