Problem Parameter and Problem Finding in Art Education

The significance of problem parameters in art education is examined. Problem parameters are delineated by the art instructor in the problem finding stage of the creative process before problem solving occurs. Problem parameters define problems and focus students' creative processes. In the delivery of an assignment, the art teacher presents problem parameters to students and students respond to parameters. A model is proposed illustrating the relationship between the presented problem parameters of art assignments and the creative processes of students. Characteristics of the instructional implementations of parameters are examined: Incomplete Parameters; Overly and Inadequately Restrictive Parameters; and Expanding and Contracting Parameters. Student responses to parameters are explored: Disregarded, Self-imposed, and Stretched Parameters. The implications of the model in art education are discussed.     

Patterns of Preference for Numerical and Verbal Probabilities

We report results of an experiment designed to test a principle formulated by Budescu and Wallsten (1995), that, when communicating uncertainty information, mode choices are sensitive to sources and degrees of vagueness. In addition, we examined subjects’ efficacy in using such uncertainty information as a function of communication mode, source, and vagueness. In phase one of the experiment, subjects in a dyad used precise (numerical) or imprecise (verbal) expressions to communicate to a remote partner precise or vague uncertainty about the likelihoods of events. Spinner outcomes were used to generate precise uncertainty while answers to almanac questions were used to elicit vague uncertainty. In phase two, subjects saw the events paired with their partners’ estimates of similar events, and were asked to gamble on one event from each pair. Communication mode preferences were measured as the relative frequency that subjects chose the numerical mode to either express or receive uncertainty information regarding the events. Efficacy was measured as the relative frequency that subjects choose from the pair the event associated with the objectively more probable uncertainty expression. Underlying uncertainty interacted with direction of communication to affect preferences for modes of expression of the probabilities. Subjects preferred precise (numerical) information, especially for precise events (spinners). For vague events (questions), their preference for precise (numerical) information was stronger when receiving than when communicating information. Similar preferences were reflected in the efficiency of subsequent gamble decisions based on the probability estimates. Specifically, decisions were more efficacious (i.e. consistent with Expected Utility) when degrees of precision in events and estimates matched. © 1997 by John Wiley & Sons, Ltd.     

Rights, Moral Values and Natural Facts: a reply to Mary Midgley on the problem of child-abuse

ABSTRACT Mary Midgley asserts that my argument concerning the problem of child-abuse was inappropriately framed in the language of rights, and neglected certain pertinent natural facts. I defend the view that the use of rights-talk was both apposite and did not misrepresent the moral problem in question. I assess the status and character of the natural facts Midgley adduces in criticism of my case, concluding that they do not obviously establish the conclusions she believes they do. Finally I briefly respond to the charge that my suggestions were illiberal.     

On “knowing your partner”: Dangerous illusions in the age of AIDS?

We identified two characteristics of the impression formation process that may cause people to underestimate the riskiness of potential sexual partners. In Study 1, participants were quite confident that they could determine whether someone was lying to them about risk-related behavior when, in reality, they could not. Particularly troubling was a “truth bias” that resulted in relatively high rates of truth detection, but poor lie detection. In Study 2, increased familiarity with a target person (who actually was HIV+) caused participants to lower their estimates of the target's riskiness, despite the fact that we explicitly warned them that the target might be HIV+. We suggest that such processes may foster the illusion of knowing one's partner when one does not.     

Correlates of parent–child communication about specific sexual topics: A study of rural parents with school-aged children

Using data from 600 parents of children aged 5 to 18, and a context-oriented, developmental socialization conceptual framework, the interrelationships between parents' perceptions of themselves, their child, and their family relationships and the amount of parent–child discussion of 16 sexuality topics were explored. Canonical correlation analysis was used to demonstrate how circumstances and contexts influence the complexity of parent–child conversations for mother–daughter, mother–son, father–son, and father–daughter dyads. Results lend support to the conceptual framework used, as well as to previous studies of this topic area. The implications of these findings for parent–child relationships and for future research on parent–child communication about sexuality are discussed.     

Technology and guidance: a balance

The following symposium discusses the place of technology in guidance and some of the concerns involved. Tiedeman, a leading authority on technological applications in guidance, takes the position that guidance technology is an important new development. Schmidt, who has written widely in the areas of psychology and counseling, questions the place of technology in guidance and society and underlines some of the concerns related to the adoption of technology. The authors' discussions of “one-way” versus “two-way” thinking and the problem of control over the technology should be of interest to readers concerned with applying technology in guidance.
