A state notation language (NOVA SKED) for the experimental control and collection of data from operant behavior experiments by Data General NOVA series minicomputers is described. NOVA SKED is based on the SKED system written for the Digital Equipment Corporation PDP8 series of minicomputers. The NOVA SKED state notation syntax enables diagramming experimental procedures directly and precisely by the operant experimenter, who need not be familiar with computers. This syntax can then be compiled by the computer into programs that operate under the SKED run-time system (RTS). The SKED RTS operates in a timesharing mode that allows up to 16 experimental stations to function simultaneously and independently from each other. NOVA SKED is a “stand-alone” system that collects and stores data on digital magnetic tape. 相似文献

Correlations of extraversion, neuroticism, and psychoticism with state anxiety, physiological arousal, and facial expressivity were assessed in 45 adolescents during a passive task (venipuncture) and an active coping task (speech). Task was a major determiner of the relationship between these variables. During venipuncture heart-rate increase was positively correlated with state anxiety, neuroticism, and anxiety expression and negatively correlated with extraversion. However, during the speech, HR change was negatively correlated with state anxiety and nonverbal indices of anxiety, but was positively correlated with extraversion and positive nonverbal expression. Skin conductance change findings were weaker but, when occurring, were in the same direction as the HR findings. Extraversion was highly associated with all nonverbal expressivity measures: inversely correlating with venipuncture and speech anxiety expression and positively correlating with venipuncture and speech positive expression. Neuroticism was positively correlated with nonverbal expression of anxiety during venipuncture but not speech. Psychoticism correlated positively with nonverbal positive expression during both venipuncture and speech. 相似文献

People prefer to make changeable decisions rather than unchangeable decisions because they do not realize that they may be more satisfied with the latter. Photography students believed that having the opportunity to change their minds about which prints to keep would not influence their liking of the prints. However, those who had the opportunity to change their minds liked their prints less than those who did not (Study 1). Although the opportunity to change their minds impaired the postdecisional processes that normally promote satisfaction (Study 2a), most participants wanted to have that opportunity (Study 2b). The results demonstrate that errors in affective forecasting can lead people to behave in ways that do not optimize their happiness and well-being. 相似文献

Adolescent drug use in the United States remains the highest in the industrialized world. Fortunately there have been significant advances in developing effective prevention programs for adolescent drug use. An important issue in evaluating such programs is that the self-report surveys have adequate psychometric properties and assess constructs targeted by an intervention. A questionnaire focusing on knowledge and drug-related measures was developed to evaluate the research-based Life Skills Training drug prevention intervention. The questionnaire showed good internal reliability, detected change from pretest to posttest, and was brief and easy to complete by 45 middle-school students. 相似文献

The nontechnical ability to identify or match argumentative structure seems to be an important reasoning skill. Instruments that have questions designed to measure this skill include major standardized tests for graduate school admission, for example, the United States-Canadian Law School Admission Test (LSAT), the Graduate Record Examinations (GRE), and the Graduate Management Admission Test (GMAT). Writers and reviewers of such tests need an appropriate foundation for developing such questions – they need a proper representation of phenomenological argumentative structure – for legitimacy, and because these tests affect people's lives. This paper attempts to construct an adequate and appropriate representation of such structure, that is, the logical structure that an argument is perceived to have by mature reasoners, albeit ones who are untrained in logic. 相似文献
