Cortical topography is one of the most fundamental organizing principles of cortical areas. One such topography - eccentricity mapping - is present even in high-order, ventral stream visual areas. Within these areas, different object categories have specific eccentricity biases. In particular, faces, letters and words appear to be associated with central visual-field bias, whereas buildings are associated with a peripheral one. We propose that resolution needs are an important factor in organizing object representations: objects whose recognition depends on analysis of fine detail will be associated with central-biased representations, whereas objects whose recognition entails large-scale integration will be more peripherally biased. 相似文献

Suicide among older women (65 +) has received very little attention despite increasing numbers of suicides in this population. An examination of national mortality data from the National Center for Health Statistics for the years 1979 through 1992 shows an increasing trend in rates of suicide among older women and a declining trend among women under 65. Over the 14-year period, firearms replaced poisoning as the most prevalent method of suicide by women 65 and over. The results seem consistent with the assertion that the availability, familiarity, and cultural acceptability of firearms may play a role in the choice of suicide method among older women. Although violent death and the use of firearms are generally associated with males in our society, the trends reported here indicate that greater attention to firearm suicides among older women is warranted. 相似文献

The present paper examines the effects of paternal relationship with sons on the sons' relationship with each other. The Biblical stories initially abound with conflict between the sons because they vie for the father's blessing and favor. The Greek stories initially show little sign of sibling rivalry because the sons band together against a threatening father. With time, paternal blessing (as exemplified by Jacob's blessing) overcomes sibling rivalry. The Greek families become more pathological with time, as the diminution of the paternal threat allows on accentuating of sibling conflict (as exemplified by the curse of Oedipus). 相似文献

Although joblessness is a major problem, no method of job-counseling has been demonstrated to be superior to usual job-finding practices. The present study describes a new type of program, which has now been evaluated experimentally in a matched-control design. The new program was conducted in a group and stressed such distinctive techniques as mutual-assistance among job-seekers, a ‘buddy’ system, family support, and sharing of job leads. In addition, the program arranged special ways of using such common practices as searching want-ads, role-playing, telephoning, motivating the job-seeker, constructing a resume and contacting friends. Within 2 months 90 per cent of the counseled job-seekers had obtained employment vs. 55 per cent of the non-counseled job-seekers. All clients who attended the program regularly obtained employment. After 3 months, 40 per cent of the non-counseled job-seekers were still unemployed. The average starting salary was about a third higher for the counseled job-seekers. The present procedure appears to be an effective method of assisting a greater proportion of the unemployed to obtain jobs and more quickly, and at a higher salary than they could obtain when they used the usual job finding procedures. 相似文献

This article is intended to serve as an introduction to the concept of the marriage contract, which has proved to be a useful clinical tool for clarification and treatment of troubled marriages. Transactional as well as intrapsychic factors are important aspects of marital dynamics. The contract concept employs both these behavioral parameters and facilitates therapeutic intervention at both levels. 相似文献

Many adults engage in ultraviolet indoor tanning despite evidence of its association with skin cancer. The constellation of behaviors associated with ultraviolet indoor tanning is analogous to that in other behavioral addictions. Despite a growing literature on ultraviolet indoor tanning as an addiction, there remains no consensus on how to identify ultraviolet indoor tanning addictive tendencies. The purpose of the present study was to translate a behavioral economic task more commonly used in substance abuse to quantify the "abuse liability" of ultraviolet indoor tanning, establish construct validity, and determine convergent validity with the most commonly used diagnostic tools for ultraviolet indoor tanning addiction (i.e., mCAGE and mDSM‐IV‐TR). We conducted a between‐groups study using a novel hypothetical Tanning Purchase Task to quantify intensity and elasticity of ultraviolet indoor tanning demand and permit statistical comparisons with the mCAGE and mDSM‐IV‐TR. Results suggest that behavioral economic demand is related to ultraviolet indoor tanning addiction status and adequately discriminates between potential addicted individuals from nonaddicted individuals. Moreover, we provide evidence that the Tanning Purchase Task renders behavioral economic indicators that are relevant to public health research. The present findings are limited to two ultraviolet indoor tanning addiction tools and a relatively small sample of high‐risk ultraviolet indoor tanning users; however, these pilot data demonstrate the potential for behavioral economic assessment tools as diagnostic and research aids in ultraviolet indoor tanning addiction studies. 相似文献

Incentives are a popular method to achieve desired employee performance; however, research on optimal incentive magnitude is lacking. Behavioral economic demand curves model persistence of responding in the face of increasing cost and may be suitable to examine the reinforcing value of incentives on work performance. The present use‐inspired basic study integrated an experiential human operant task within a crowdsourcing platform to evaluate the applicability of behavioral economics for quantifying changes in workforce attrition. Participants included 88 Amazon Mechanical Turk Workers who earned either a $0.05 or $0.10 incentive for completing a progressively increasing response requirement. Analyses revealed statistically significant differences in breakpoint between the two groups. Additionally, a novel translation of the Kaplan‐Meier survival‐curve analyses for use within a demand curve framework allowed for examination of elasticity of workforce attrition. Results indicate greater inelastic attrition in the $0.05 group. We discuss the benefits of a behavioral economic approach to modeling employee behavior, how the metrics obtained from the elasticity of workforce attrition analyses (e.g., P max) may be used to set goals for employee behavior while balancing organizational costs, and how economy type may have influenced observed outcomes. 相似文献
