ABSTRACT
Background
Postnatal mental illnesses are associated with less maternal sensitivity. Differences in how mothers with and without mental illness process infant emotions could explain this. People with mental illness in non-perinatal populations show certain processing patterns when viewing emotional faces, but it is not clear whether these patterns are present in mothers. 相似文献143.

A first-person shooter video game was adapted for the study of choice between smaller sooner and larger later rewards. Participants chose when to fire a weapon that increased in damage potential over a short interval. When the delay to maximum damage was shorter (5–8 s), people showed greater sensitivity to the consequences of their choices than when the delay was longer (17–20 s). Participants also evidenced a magnitude effect by waiting proportionally longer when the damage magnitudes were doubled for all rewards. The experiment replicated the standard magnitude effect with this new video game preparation over time scales similar to those typically used in nonhuman animal studies and without complications due to satiation or cost. 相似文献

Conventional interventions with perpetrators of domestic violence are marginally effective. Given these results, researchers and practitioners are beginning to focus on identifying ways to improve domestic violence treatment outcomes. This article describes how a rural state-sponsored domestic violence offender program utilizes a treatment approach known as Mind-Body Bridging to help its clients overcome their abusive behaviors. Preliminary findings from an ongoing outcome study are also reported. According to these findings, the program has a high completion rate coupled with a low recidivism rate. Ninety-three percent (82 of 88) of the clients who have participated in this program completed the program, and just 7%?(6 of 82) of those who completed the program reoffended during the follow-up period, which ranged from 9 to 27 months. 相似文献

I examined the reconstructive processes of remembering past events when new information is made available. Analyses with a variety of materials and conditions failed to reveal effects for distortion in recognition memory for retrospective label manipulations. Effects of prior knowledge were consistently strong and highly resistant to subsequent biasing information. The results suggest that people are less susceptible to thematic-based, stereotypic information and possess a memory network more flexible than traditional research implies. 相似文献

The Marr-Ullman model for motion detection in the human visual system functions by means of the dual input of polarity-specific edge detectors and luminance change detectors. Moulden and Begg (1986) found a polarity-specific motion aftereffect which they claimed provided support for this dual input model. The logic of their experiment is examined, and it is shown that several additional predictions arise from the Marr-Ullman model, which were not supported by Moulden and Begg's study. A more powerful experiment was carried out and these additional predictions were disconfirmed, although the polarity-specific effect did emerge. A consideration of alternative explanations of this effect led to a second experiment in which an attempt was made to discover the actual determinants of the effect. This revealed that polarity-specific units are unlikely to play any part in the phenomenon. It was concluded, in the light of this and other evidence, that one of a class of alternative models is more likely to be the actual mechanism for motion perception. However, careful consideration of the Marr-Ullman model indicated that it may be untestable in principle if various differentially weighted levels of neural integration are envisaged. 相似文献

The division of cognitive labor is fundamental to all cultures. Adults have a strong sense of how knowledge is clustered in the world around them and use that sense to access additional information, defer to relevant experts, and ground their own incomplete understandings. One prominent way of clustering knowledge is by disciplines similar to those that comprise the natural and social sciences. Seven studies explored an emerging sense of these discipline-based ways of clustering of knowledge. Even 5-year-olds could cluster knowledge in a manner roughly corresponding to the departments of natural and social sciences in a university, doing so without any explicit awareness of those academic disciplines. But this awareness is fragile early on and competes with other ways of clustering knowledge. Over the next few years, children come to see discipline-based clusters as having a privileged status, one that may be linked to increasingly sophisticated assumptions about essences for natural kinds. Possible mechanisms for this developmental shift are examined. 相似文献
