Attitudinal and Normative Factors as Determinants of Gay Men's Intentions to Perform AIDS-Related Sexual Behaviors: A Multisite Analysis1

The purpose of this study was to test the applicability of the theory of reasoned action as a basis for understanding and predicting gay men's intentions to perform AIDS-related sexual behaviors. A total of 314 self-identified gay or bisexual men from Seattle, Denver, and Albany participated in the study. They were asked to indicate their intentions to perform 15 specific sexual behaviors chosen to represent different degrees of risk of contracting AIDS or other sexually transmitted diseases. In addition, they were asked to respond to items measuring the attitudinal and normative considerations regarding each behavior. As expected, the results showed that the gay men's intentions were significantly predicted by the two factors. More interesting, it was found that, although attitudes are consistently the more important determinants of intentions for all the respondents, the importance of normative considerations varies across cities. This difference in normative considerations is interpreted in light of the differences in the structure of the three gay communities. Implications for designing sample-specific intervention programs are discussed.     

The role of balance dynamics in the active perception of orientation.

The Stoffregen and Riccio (1988) hypothesis that perceived orientation is determined primarily by balance dynamics was tested. Perception of orientation was evaluated in the context of a task that required Ss to control the roll orientation of a device in which they were seated. The device's direction of balance was manipulated across trials and thus was independent of gravity. Eighteen Ss participated in the investigation. After each trial, Ss estimated their mean tilt with respect to upright. Correlations of perceived tilt with tilt from balance were consistently higher than the correlations with gravity tilt. The dominance of balance over gravity depended on the magnitude of tilt from balance.     

Sources of variability in perceptions of and responses to sexual harassment

Social exchange theory was used to explain sexual harassment interactions in terms of perceived or actual inequities in incurred costs or rewards between targets and perpetrators. A factorial experiment was conducted in which the effects of severity of harassment, target response, target gender, and rater gender on perceptions of harassment, perpetrator appropriateness and target appropriateness and suggested responses to harassment were examined. Ninety-four male and 116 female students from two eastern universities served as subjects. The sample was approximately 90% Caucasian and was composed of traditional (18–22-year-old) undergraduates. Results indicated that all independent variables affected perceptions of and responses to sexual harassment situations.     

Nontemporal measures of performance on a computerized block design task

A computerized block design task was developed which records temporal and nontemporal measures of performance. This study evaluates the reliability of the measures and reports their intercorrelations. With one exception, the measures showed moderate to good reliability. The results indicate that increasing the difficulty of the task and testing a more diverse sample may be necessary for improved reliability. A nontemporal method of scoring a block-design task would be useful when testing persons who have handicaps affecting motor skills, but no central nervous system deficits.

Preconceptional family health evaluation: A regional education program for family planning clients and health professionals

The Preconceptional Family Health Evaluation Program was a regional project developed and funded for 2 years by the New England Regional Genetics Group (NERGG) to educate family planning health professionals about genetics, and to offer family planning clients preconceptional identification of genetic and environmental exposure risks. To meet these goals, genetic education was provided on a regional basis to 45 family planning professionals. A self-administered family health risk questionnaire adaptable to individual family planning settings was developed. Five hundred and twenty-nine family planning clients voluntarily completed the questionnaire. Cigarette smoking (35%) and alcohol use (57%) were two major categories of risks identified. The Preconceptional Family Health Evaluation Program was well received by all participants and provided an effective means for regional education of family planning health professionals. As a result of the program, state program planners, clinical genetics services, and family planning health professionals developed a strong relationship that will serve future educational and genetic risk screening efforts.     

A HyperCard stack for the creation of graphically organized glossaries

Many students find it difficult to transform expository text and lectures into well-organized mental constructs. Studies show that learning of this type can be enhanced by the use of graphic organizers that depict relationships among concepts by diagramming them as a tree structure. In order to incorporate all concepts taught in a course into a single graphic organizer, a HyperCard authoring shell was developed to expedite drawing tree diagrams and linking each concept in the diagram to a definition. The authoring features of the stack and its application to an abnormal psychology course are discussed in this article.     

Measuring the stop point of rapid smoking

A method and an apparatus are described for measuring the point at which subjects elect to stop smoking when cigarette smoke is delivered more rapidly than in typical smoking. The device allows either the subject or the experimenter to control the volume of smoke and the interval between puffs. The device delivers reliable quantities of particulate matter from cigarette smoke. Subjects retested a week apart exhibited consistent stopping points.     

IS NONDEFECTIVELY JUSTIFIED TRUE BELIEF KNOWLEDGE?

The traditional conception of knowledge as justified true belief is refuted in two famous counterexamples by Edmund L. Gettier. Roderick M. Chisholm has attempted to rescue a version of the traditional conception by distinguishing between defective and nondefective kinds of justification, and redefining knowledge more specifically as nondefectively justified true belief. Chisholm's revised definition avoids Gettier's counterexamples, but goes too far in the opposite direction, imposing conditions that are too narrow and not jointly necessary for knowledge. Chisholm's definition excludes some claims that intuitively constitute genuine knowledge¹ by entailing that if a true belief is invalidated as knowledge when defectively justified by a total body of evidence that also makes evident at least one false proposition, then no knowledge whatsoever can be supported by the same evidence. An alternative analysis of knowledge is proposed, according to which the potential loophole between the state of affairs that justifies belief in a proposition, and the state of affairs that makes the proposition true, permitted by the traditional concept of knowledge and discovered by Gettier's counterexamples, is closed by redefining knowledge as semantically-epistemically evidentially relevant justified true belief.
