Predictions made by 4 competing models of time use by children with AD/HD were tested using a computerized version of the Matching Familiar Figures Test in 2 studies. In Study 1 teacher-identified AD/HD children (N = 10) and non-AD/HD controls (N = 10) completed the task under 3 different trial duration conditions (5, 10, and 15 s). In Study 2 the same task was completed by a group of children with a diagnosis of Hyperkinetic Disorder (N = 12) and controls (N = 12). In both studies AD/HD children performed poorly on trials of both 5- and 15-s duration but as well as controls on the 10-s trials. This quadratic function provided support for the State Regulation Deficit model of time use in AD/HD. The value of tailoring the temporal features of learning contexts to the conceptual style of AD/HD children is discussed. 相似文献

The majority of scholarly management studies are based on self-report surveys. Consequently, the need to control for social desirability response is important, although few management studies in fact include the use of relevant scales commonly incorporated in psychology research. The full Marlowe–Crowne scale is disaffectingly long for senior-manager sample usage, so one of its short forms is more practical. However, the reliability of the most popular of these, the Strahan–Gerbasi scale, has not been tested with senior-manager samples. This study tests the scale amongst several senior-manager samples and finds it consistently lacks adequate reliability and unidimensionality. 相似文献

Whereas humans display base-rate neglect in a behavioral analogue of the base-rate problem, pigeons have been shown to behave optimally in a comparable task, appropriately weighting base-rate and case-cue information. Previous studies have shown that prior experience may interfere with optimal decisions for human subjects, a result consistent with the position that poor and illogical decisions often follow from the misapplication of learned rules. The present study shows that pigeons will also display base-rate neglect if given extensive pretraining with informative case cues. Two experiments with pigeons, in a matching-to-sample procedure designed to mimic the classic base-rate problem, show that pigeons display base-rate neglect after extensive pretraining with the matching task. 相似文献

Neurons were found in the rhesus macaque anterior orbitofrontal cortex that respond to novel but not to familiar visual stimuli. Some of these neurons responded to all novel stimuli, and others to only a subset (e.g., to novel faces). The neurons have no responses to familiar reward- or punishment-associated visual stimuli, nor to taste, olfactory or somatosensory inputs. The responses of the neurons typically habituated with repeated presentations of a novel stimulus, and five presentations each 1s was the median number for the response to reach half-maximal. The neurons did not respond to stimuli which had been novel and shown a few times on the previous day, indicating that the neurons were involved in long-term memory. The median latency of the neuronal responses was 120 ms. The median spontaneous firing rate was 1.3 spikes/s, and the median response to novel visual stimuli was 6.0 spikes/s. These findings indicate that the long-term memory for visual stimuli is information that is represented in a region of the primate anterior orbitofrontal cortex. 相似文献

Dilemmas in military medical ethics since 9/11 总被引:2,自引:0,他引:2

The attack on the United States by terrorists on 9/11 and the war with Iraq have raised new ethical questions for the military and for military physicians (Herman 2002; Elshtain 2003). How and when attacks may occur now is less predictable. Planes have been hijacked, and persons dressed as civilians may carry bombs to blow themselves and others up. These dangers pose an increased threat, and, thus, there is a need for new defensive measures. How far these measures should go is, however, greatly open to debate. One of the most difficult ethical question raised for the military and military doctors by these developments is what interrogation methods are permissable when questioning captured terrorists. The licitness of different interrogation practices is, however, only one of the ethical problems potentially encountered by military physicians now having to treat terrorists and POWs. The following discussion presents the major concerns regarding this and other issues. 相似文献
