Empiricism,judgment, and argument; Toward an informal logic of science

In an attempt to explore the role of argumentation in scientific inquiry, I explore the conception of argument that appears fruitful in the light of the recent trends in the philosophy of science, away from logical empiricism, and toward a greater emphasis on change, disagreement, and history. I begin by contrasting typical instances philosopers theories of both empiricism and apriorism, with typical instances of scientists uses of these two attitudes, suggesting that such practice shows a judiciousness lacking in epistemological theory. Then I examine at some length three important version of scientific judgement, namely Einstein's opportunism, Boltzmann's pluralism, and Huygens's eclecticism. I go on to discuss some recent work in the philosophy of science, exploring connections between the notion of judgment and Feyerabend's anarchism, Harold Brown's view of rationality, and Dudley Shapere's analysis of scientific change. All of this suggests a notion of argument in the sense of informallogic, and I examine some aspects of Galileo's work in its terms.     

The Vocational Preference Inventory scores and environmental preferences

This study investigated the relationship between vocational interest as measured by the Vocational Preference Inventory and preferences of 175 undergraduates for structured or unstructured environments. Males having clear-cut preferences for structured situations had significantly higher Realistic-Conventional scores than those not having those preferences (p < .05). Additionally, males with structured preferences had significantly lower Social-Artistic scores (p < .025). Results for females were similar, but not statistically significant. Males also had significantly higher (p < .01) Realistic-Conventional scores than females. The significant relationships between VPI scores and preferences for structured and unstructured situations support Holland's contention that interest scores are expressions of personality needs.     

The structure of values: Conceptions of the desirable

The study aim was to define currently discernible conceptions of the desirable. An inventory of personal value statements was constructed, administered to two large samples, and factor analyzed. Twelve first order and four higher-level dimensions were identified in both samples. An hypothesis that liberal-conservative attitudes were predictable to a high degree from the authoritarian value orientation was tested and confirmed. Each of the four higher level dimensions was interpretable as a specific ethic or organized set of rules that guide conduct. The four ethics or value dimensions were labeled Acceptance of Authority, Work Ethic, Humanistic Orientation, and Hedonistic Orientation.     

The structure of assertiveness: A confirmatory study

Study aims were to establish the dimensional structure of assertiveness as measured by the Personal Relations Inventory² (PRI) and to estimate the reliability and stability of the measures derived. The item responses of a sample of 215 high school and college men and women were intercorrelated and analyzed by the method of principal components. The analysis confirmed the four hypothesized dimensions of Social Assertiveness, Defense of Rights, Independence, and Directiveness. In a second sample of 75, the PRI was compared with the Adult Self-Expression Scale (ASES). Since the total scores of the two inventories correlated 0.72 some evidence of concurrent validity has been shown.     

Patterns of adolescent involvement in problem behaviors: Relationship to self-efficacy,social competence,and life events

Using a sample of 556 adolescents from a suburban community, patterns of various adolescent problem behaviors (e.g., delinquent behavior, smoking, use of alcohol or drugs) and their links to self-efficacy, social competence, and life events were examined. Cluster analysis was conducted to identify four subgroups of adolescents who showed distinct patterns of problem behaviors. These clusters were compared on the measures of self-efficacy, social competence, and life events. Overall results suggest there are meaningful links between adolescents’ problem behavior patterns and self-efficacy, the amount and quality of participation in various after school activities, and life events. For example, a subgroup of adolescents who showed uniformly low prevalence of all problem behaviors reported more positive academic self-efficacy, more active participation in sports and nonsports activities, more positive life events, and fewer negative events than adolescents who were involved in multiple problem behaviors. Implications for prevention and future research on adolescent problem behaviors are discussed.     

Comparison of extra- and within-stimulus prompting to teach prepositional discriminations to preschool children with developmental disabilities

Comparison of extra- and within-stimulus prompting to teach prepositional discriminations to preschool children with developmental disabilities

This study compared extra-stimulus to within-stimulus prompts in teaching children with developmental disabilities to discriminate the prepositional concepts In and On. Five preschool-aged children who had difficulty discriminating verbal instructions participated. Extra-stimulus prompts involved modeling, gestures, positioning, and auditory cues which did not form part of the target discrimination. Within-stimulus prompts manipulated the volume and intonational pattern of the verbal stimuli. Four children did not learn the discrimination with extra-stimulus prompting. All four of these children, plus a fifth child who did not have prior experience with extra-stimulus prompting, reached criterion in the within-stimulus prompting condition. The success of the within-stimulus prompts may be related to their enhancing phonetic differences between the verbal stimuli.     

Interracial Friendships, Multicultural Sensitivity, and Social Competence: How Are They Related?

The present study used sociometric questionnaires to examine the relationship between interracial friendships, multicultural sensitivity, and social competence in fifth-grade children. Participants completed four questionnaires that provided information about who their friends were, friendship quality, racial and ethnic attitudes, and social competence. Results indicated that fifth-grade girls with high-quality interracial friendships indicated less minority rejection, more diverse social networks, and more sociability and leadership characteristics than their peers with no or low-quality interracial friendships. Similar results were not found for boys in the study. These findings have important educational and clinical implications.     

Physical Attractiveness Contrast Effect and the Moderating Influence of Self-Consciousness

Separate studies provided evidence of amoderating effect of public selfconsciousness (trait)and public self-awareness (state) on the physicalattractiveness contrast effect involving socialcomparison between the self and others. Generally, whenexposed to photographs of attractive women withidealized physiques, women's self-perceptions of theirown physical attractiveness, social physique anxiety, and social self-esteem were each negativelyaffected. However, these negative contrast effects weremost apparent among women with high publicself-consciousness (trait assessment, Study 1) or highpublic self-awareness (state inducement, Study 2).Implications of these findings are considered.
