The transfer of respondent eliciting and extinction functions through stimulus equivalence classes

Two studies investigated the transfer of respondent elicitation through equivalence classes. In Experiment 1, match-to-sample procedures were used to teach 8 subjects two four-member equivalence classes. One member of one class was then paired with electric shock, and one member of the other class was presented without shock. All remaining stimuli were then presented. Using skin conductance as the measure of conditioning, transfer of conditioning was demonstrated in 6 of the 8 subjects. In Experiment 2, similar procedures were used to replicate the results of Experiment 1 and investigate the transfer of extinction. Following equivalence training and conditioning to all members of one class, one member was then presented in extinction. When the remaining stimuli from this class were then presented, they failed to elicit skin conductance. In the final phase of the experiment, the stimulus that was previously presented in extinction was reconditioned. Test trials with other members of the class revealed that they regained elicitation function. These results demonstrate that both respondent elicitation and extinction can transfer through stimulus classes. The clinical and applied significance of the results is discussed.     

Employment status and the attitudes and behavior of higher status women volunteers, 1975 and 1992: A case study

This study examines the relationships between employment status and women's attitudes toward and participation in a higher status voluntary service organization. Data were gathered in 1975 and 1992 from a sample of chapters of the International Association of Women (a pseudonym). The 1992 sample included three percent who reported a racial or ethnic identification other than white. Drawing on several theoretical perspectives, we expected to find differences in the attitudes and level of participation of employed versus non-employed members that would have important effects on organizational functioning. However, few differences in the attitudes of members employed full time, part time, and not in the labor force were found in either 1975 or 1992. There were, however, differences in behavior. Employed members reported spending much less time on organizational activities and were less likely to assume leadership roles, but these differences diminished between 1975 and 1992 as employed women became numerically dominant in the organization, suggesting that the growing presence of employed women in IAW led to the development of informal norms and new policies about the amount of time members should devote to the organization and a corresponding loss in the total number of volunteer hours devoted to it.     

I can be a bum: Knowledge about abilities and life style in vocational behavior

From recent reviews of the vocational behavior literature, it is suggested that vocational theory and research need to move toward models which take seriously the problems generated by normative theories. Such a model is presented which uses a cognitive model of behavior and incorporates life style parameters. The research implications of the model are outlined.

Comparison of two creativity style measures

The purpose of this study was to examine the relation between two measures of creativity style for a sample of beginning teachers. 116 student teachers enrolled in an undergraduate teacher-education program in a medium-sized, metropolitan university completed the Kirton Adaption-Innovation Inventory and Basadur Creative Problem Solving Profile measures. A preference for an Innovator style (higher scores on Kirton's inventory) was correlated with the Generator profile on the Basadur profile (r=.36, p<.01). The KAI Efficiency scores, suggesting a preference for broad, global ideas as opposed to narrow, specific ones, was correlated with the Basadur Conceptualizer scores (r=.26, p<.01). Implications are discussed for teachers who must adapt to newer instructional and assessment methods designed to foster students' higher-level thinking skills.     

Problem Solving Style and Beliefs about Teaching,Learning, and Problem Solving

Seventy-four pre-service teachers in an urban graduate school of education were administered VIEW: An Assessment of Problem Solving Style and a questionnaire in which they were asked to rate the importance of numerous principles of learning, teaching, and problem solving. Judges had previously classified these principles according to the six different VIEW problem solving styles (Explorer, Developer, External, Internal, Person-oriented, Task-oriented). Participants categorized by a particular style rated more highly those principles that matched their style. Implications for instruction and the development of problem solving skills are discussed.     

McColl and Minimization

In 1952, Quine showed that the problem of reducing a propositional formula to a simplest normal equivalent can be solved in two steps, viz., (i) express the given formula, Φ, equivalently as the disjunction of all its prime implicants, and (ii) find all non-redundant disjunctions of the latter that are equivalent to Φ (Quine 1952 Quine, W. V. 1952. ‘The problem of simplifying truth functions’. American Mathematical Monthly, 59: 521–531. [Taylor &; Francis Online] , [Google Scholar]). However, it seems not generally known that an ingenious form of the same two-step process was published by Hugh McColl in 1878.
