Detection of deception and confirmation of truth telling with conventional polygraphy raised a host of technical and ethical issues. Recently, newer methods of recording electromagnetic signals from the brain show promise in permitting the detection of deception or truth telling. Some are even being promoted as more accurate than conventional polygraphy. While the new technologies raise issues of personal privacy, acceptable forensic application, and other social issues, the focus of this paper is the technical limitations of the developing technology. Those limitations include the measurement validity of the new technologies, which remains largely unknown. Another set of questions pertains to the psychological paradigms used to model or constrain the target behavior. Finally, there is little standardization in the field, and the vulnerability of the techniques to countermeasures is unknown. Premature application of these technologies outside of research settings should be resisted, and the social conversation about the appropriate parameters of its civil, forensic, and security use should begin. 相似文献

In-depth structured interviews of 309 high school graduates judged to be non-college-bound explored perceptions of their (a) educational experiences, (b) vocational experiences, (c) self-concepts, and (d) family relationships. Interview data were compiled two years after high school graduation from subjects residing in urban, “rurban,” and rural environments in four mid-central states. Content analysis of written reports of subjects perceptions resulted in four major conclusions: (a) employment-bound, non-college-oriented students perceive the school, the counselors, and other personnel within the school as favoring the college-bound student; (b) counselors were not perceived as being helpful in assisting employment-bound youth to satisfactory vocational decisions; (c) subjects were unable to articulate meaningful concepts of self; and (d) generally, they did not perceive parents as being at all helpful in resolving personal, educational, and vocational problems. 相似文献

Four experiments are described that determine whether or not syntactic complexity affects the visual perception of rapidly presented word sequences. The results indicate that sentences containing only one sentence in the underlying structure are more accurately reported than sentences containing two underlying sentences. It is shown that this result is not due solely to distortion of the input, but is likely to reflect the rate at which structural representations of the input can be developed. 相似文献

The present experiment demonstrates that the effects of delay of knowledge of results (KR) in a line drawing task depend upon the dependent variable which is considered and the original response tendency of the subjects. Delay of KR interfered with the acquisition of the correct response when number of correct responses is the dependent variable. When KR was omitted the immediate-KR group continued to make more correct responses than the delayed-KR group. However, there was a significant reduction in correct responses for both groups. When absolute error was the response measure there were no significant differences between immediate-and delayed-KR groups either during acquisition or extinction. Analysis of the type of response made during extinction suggested that the overshooting effect obtained by previous investigators may be typical of short responders trained under conditions of immediate reinforcement but not of those trained under delayed-KR.
Greenspoon and Foreman (1956) obtained clear cut evidence that the effectiveness of knowledge of results (KR) in a line drawing task varies inversely with the time delay between the response and KR. On the other hand, Bilodeau and Bilodeau (1958) were unable to demonstrate a similar effect in five different experiments. Bilodeau and Ryan (1960) hypothesized that the Greenspoon and Foreman findings could not be replicated and they did in fact obtain null results. However, Dyal (1965) has recently replicated the Greenspoon and Foreman results for the case of a 30 sec. delay interval.
The purpose of the present experiment is twofold: (a) to provide replication of Green-spoon and Foreman's study at the 20 sec. delay interval used by Bilodeau and Ryan, and (b) to determine the effect of elimination of KR on a simple motor response which has been formed on the basis of KR. 相似文献

It has been claimed that the nearly logarithmic form of some category scales supports Fechner's law. However, by assuming that the concepts of similarity and difference are quantitatively complementary, it is possible to deduce the category scale equation from the similarity function. Thus, the category scale equation cannot be taken as evidence of the validity of Fechner's law. 相似文献

This article is the second in an ongoing series devoted to a critical reassessment of the status of diversity-sensitive counseling. The current discussion focuses on the use of existing counseling theories and interventions in a diversity-sensitive counseling context, and potential limitations of affirmative action in the American Counseling Association's organizational structure and in counselor preparation programs. Inconsistencies are noted between the strategies now being used to achieve diversity and the philosophical foundations of the counseling profession. At issue are the conflicting values of various constituencies within the Association. 相似文献
