Choice-induced preferences in the absence of choice: Evidence from a blind two choice paradigm with young children and capuchin monkeys

In two studies, we provide a test of the revealed-preferences account of choice-induced preferences. To do so, we introduce a blind two-choice task in which preferences cannot guide choices. Children chose between two similar objects while ignorant of the objects’ identities, and then chose between the rejected alternative and a third similar object. Monkeys were given an illusion of choice between two similar objects, and then chose between the rejected object and a third similar object. Both children and monkeys preferred the third object, indicating that they devalued the rejected object. This response pattern did not occur when the children and monkeys were not given the opportunity to choose between the two initial items. These results provide evidence against a revealed-preferences account of choice-induced preferences and demonstrate that the process of making a choice itself induces preferences.     

A study of the personal meaning of suicide in the context of Baechler's typology

This study investigates suicide from the vantage point of the suicidal person by analyzing the personal meaning(s) of the act for the individual. Twenty-seven suicidal persons and survivors contributed to the research. Their individual recollections are studied and ordered within the framework of Jean Baechler's approach (as presented in his book Suicides). The study indicates that there is, in each case, an identifiable purpose or a pattern of purposes that can be categorized within a restricted and meaningful system, which may help the observer understand what human beings are doing when they want to end their lives.

Manipulating parameters of reinforcement to reduce problem behavior without extinction

Differential reinforcement of alternative behavior (DRA) most often includes extinction as a treatment component. However, extinction is not always feasible and it can be counter‐therapeutic if implemented without optimal treatment integrity. Researchers have successfully implemented DRA without extinction by manipulating various parameters of reinforcement such that alternative behavior is favored. We extended previous research by assessing three participants' sensitivities to quality, magnitude, and immediacy using arbitrary responses and reinforcers that maintain problem behavior. The results were used to implement an intervention for problem behavior using DRA without extinction. Our findings indicate that arbitrary responses can be used to identify individual and relative sensitivity to parameters of reinforcement for reinforcers that maintain problem behavior. Treatment was effective for all participants when we manipulated parameters of reinforcement to which they were most sensitive, and, for two participants, the treatment was less effective when we manipulated parameters to which they were least sensitive.     

全球基本健康研究

在过去的10年间,世界各国的卫生研究意识都在增强,每个国家都很重视基本的国家研究在医疗卫生及医疗卫生系统中的作用。基因组计划将改变我们理解健康和疾病的方式,导致人们对“预防性治疗”的需要,但其带来的负面影响不可忽视。     

Disgusting smells cause decreased liking of gay men

An induction of disgust can lead to more negative attitudes toward an entire social group: Participants who were exposed to a noxious ambient odor reported less warmth toward gay men. This effect of disgust was equally strong for political liberals and conservatives, and was specific to attitudes toward gay men-there was only a weak effect of disgust on people's warmth toward lesbians, and no consistent effect on attitudes toward African Americans, the elderly, or a range of political issues.     

Locomotor Analysis of the Taiep Rat

Locomotor activity (tremor, ataxia, immobility, epilepsy, and paralysis) in the taiep rat, which suffers from a myelin deficient disorder, has not been previously documented. This study used walking track analysis of footprints to analyze locomotor activity in the taiep rat in comparison to normal, age-matched controls. The results confirmed differences between normal and taiep rats in terms of stride length, step length, and stride width. In addition, we found significant interactions between age and condition for stride and step length. The results suggest that locomotor analysis is a sensitive indicant of myelin deficiency. The results are discussed in terms of the underlying myelin deficiency and possible treatment regimens.     

Understanding children's and adults' limitations in mental state reasoning

Young children exhibit several deficits in reasoning about their own and other people's mental states. We propose that these deficits, along with more subtle limitations in adults' social-cognitive reasoning, are all manifestations of the same cognitive bias. This is the 'curse of knowledge' - a tendency to be biased by one's own knowledge when attempting to appreciate a more na?ve or uninformed perspective. We suggest the developmental differences in mental state reasoning exist because the strength of this bias diminishes with age, not because of a conceptual change in how young children understand mental states. By pointing out the common denominator in children's and adults' limitations in mental state reasoning we hope to provide a unified framework for understanding the nature and development of social cognition.
