Similar as well as dissimilar contextual stimuli increase rated similarity

Contextual stimuli from one category increase the rated similarity of stimuli from a second category. In Experiment 1, associates of one of the members of pairs of target words increased the rated similarity of the members slightly more than did much less similar contextual stimuli. In Experiment 2, contextual category names and good exemplars increased the rated similarity of pairs of poor to medium target exemplars and were also rated as more similar to these targets than the targets were to each other. In both cases, the category names resulted in the stronger effect. This ability of contextually similar stimuli to increase rated similarity opposes the distance-density and averaging-judgmental theories of the effect of context on similarity. However, the theory that a positive association exists between the perceived similarity of stimuli and the strength of the category to which they belong explains how both contextually dissimilar and contextually similar stimuli can increase rated similarity.     

Religion,Type A behavior,and health

In a study of air traffic controllers, religious differences are found in the way Type A behavior is associated with several health status indicators. Associations between the Jenkins Activity Survey (JAS) and physical illness incidence, health-promotive behavior, diastolic and systolic blood pressure, subjective distress and impulse control problems, and alcohol consumption are examined by religious attendance, religious affiliation, and change in affiliation. Findings confirm that Type A does not vary significantly by religion. However, there are several significant findings between Type A and various health indicators. Type A is associated with illness incidence, overall and more strongly in several religion, subgroups. Type A and alcohol consumption are related positively in Protestants and converts, and negatively in churchgoing Catholics. Type A is related to impulse control problems in churchgoing Protestants and to subjective distress in churchgoing Catholics. Finally, in individuals with weak or no religious ties, Type A is associated with lower blood pressure. This last finding suggests that in some people (for example, the irreligious or unchurched), the coronary-prone behavior pattern may have cardiovascular effects which are salutary in at least one respect.The authors wish to thank Dr. Kyriakos S.

Are indefinite descriptions ambiguous?

I have benefited greatly from discussing the issues addressed in this paper with Michael Liston, John Vickers and Mark Wilson.     

A survey of psychologists employed in business and industry

Responses to a questionnaire from 78 members of the Metropolitan New York Association for Applied Psychology provided the following results. A majority of respondents found their first jobs as applied psychologists through informal networking techniques such as personal recommendations or self-starter methods such as sending out resumes. Over 75% of the respondents rated their graduate institutions as good or excellent. However, an increase in the applied focus of these programs was strongly urged, and opinions about graduate faculties were mixed. Obtaining applied work experience or relevant internships was the most often mentioned advice for seekers of similar positions.Appreciation is expressed to Harold Takooshian of Fordham University who first aroused our interests in this topic as an area for research and to Bruce Biskin of AICPA, Dennis Hawver and Tony Zinsser of the Hawver Group, Ted Grant and Michael Secunda of Manufacturers Hanover, and Tom Novak of Young & Rubicam for serving as pre-test subjects for the questionnaire of this study.     

Humor and the coronary-prone behavior pattern

The belief is widely held that humor is related to recovery from, and perhaps an increased resistance to, coronary and other stress-related diseases. Such generalizations do not typically distinguish between benign and hostile humor. In the present research, the relationship between a measure of proneness to coronary heart disease (CHD) and appreciation of hostile and nonhostile humor is examined. In two studies, one with college students and one with patients suffering from CHD, the relationship between humor preferences and the coronary-prone (Type A) behavior pattern was examined. Each subject was given the Jenkins Activity Survey as a measure of the coronary-prone personality type, and aggressive and nonaggressive jokes to rate for funniness. Hostile humor was preferred to nonhostile humor by all groups, but among those suffering from CHD, those who could be classified as “Type B’s” preferred nonhostile humor. The results indicate that those less prone to CHD appreciate both hostile and nonhostile humor, while Type A’s seem to enjoy hostile humor only.     

COVARIATION WITHIN FUNCTIONAL RESPONSE CLASSES: IMPLICATIONS FOR TREATMENT OF SEVERE PROBLEM BEHAVIOR

Two studies examined the effects of a reductive treatment versus instruction-based treatments on the generalized reduction of problem behaviors. Each study involved a detailed analysis of multiple problem behaviors performed by school-aged youth with severe intellectual disabilities. The analysis examined the contrasting effects of one of two different positive intervention procedures (teaching a positive alternative behavior or providing additional teacher assistance during instruction) versus blocking and/or verbally reprimanding a problem behavior. The focus of each analysis was on the covariation of multiple problem behaviors within functional response classes. Results of the investigation indicated that when only one member of the response class was blocked, a collateral increase was observed in one or more different problem behaviors from the same response class. Alternatively, when 1 participant was taught a functionally equivalent mand response, all problem behaviors in the response class were reduced. Problem behaviors also were reduced for the remaining participant by presenting antecedent teacher assistance. Implications of the research extend to analysis of covariation within response classes and to procedures that result in generalized reduction of problem behaviors within a response class.     

Output and retrieval interference in the missing-number task

Three experiments are reported that represent a reexamination of the missing-number method (Buschke, 1963b) of estimating short-term memory span. The missing-number task involved presenting a random sequence of all but one of the numbers of a known reference set and asking subjects to identify the missing number. Experiment 1 introduced a modified missing-number task that included two missing items and two choices made by the subject. With a large decline in performance for the second choice relative to the first, it is possible that only the second choice was subject to output or retrieval interference. An alternative explanation is that subjects output the number with the weakest memory representation as their first response. By postcuing subjects to report their two choices in a forward or backward sequence, Experiment 2 provided evidence against the importance of output interference and support either for the importance of retrieval interference or for the "weakest-first" hypothesis. However, with a paradigm that replaced only correctly identified missing numbers, a prediction that subjects would select the number with the weakest memory representation as their first response was not confirmed in Experiment 3. Instead, retrieval interference was implicated to explain the first-choice superiority found in Experiments 1 and 3. The results were interpreted in terms of the TODAM model of Murdock (1982, 1987, in press).     

Introduction to the epistemology of the brain: Indeterminacy,micro-specificity,chaos, and openness

Given that the mind is the brain, as materialists insist, those who would understand the mind must understand the brain. Assuming that arrays of neural firing frequencies are highly salient aspects of brain information processing (the vector functional account), four hurdles to an understanding of the brain are identified and inspected: indeterminacy, micro-specificity, chaos, and openness.My thanks to the editor of this issue and an unnamed referee for many pointed comments and helpful suggestions.
