Defensiveness, intimacy, and heterosexual attraction

A previous study by Dion and Dion (1975) revealed that highly defensive individuals were less likely to report having experienced romantic love than less defensive persons. The hypothesis that this finding might reflect differential reactions to interpersonal intimacy was directly examined in the present study using a self-disclosure paradigm. To assess subjects' defensiveness, undergraduate women first completed the Marlowe-Crowne Social Desirability Scale. In a second session, subjects were exposed to high and low disclosing targets of the same and opposite sex and chose discussion topics for each target. On intimacy of self-disclosure, a “reciprocity effect” occurred: subjects chose more intimate topics for high vs low-disclosing targets. However, highly defensive women gave a less favorable self-presentation to male vs female targets. They also expressed less liking for high compared to low intimate targets and males vs females than less defensive subjects. The implications of these results for heterosexual attraction were discussed.     

Microcomputers big and little: Selecting a low-cost laboratory computer network

Characteristics of microcomputers are described affecting suitability for low-cost laboratory network use. Assuming a network of small microcomputers with interfaces for applications and a larger one for program development, 6502-based hobbyist computers appear cheapest at this time, while microcomputers imitating minicomputers have the best hardware and software support.     

Valence and instrumentality contributions to understanding occupational preference

Studies on the expectancy model have presented conflicting results concerning the usefulness of valence ratings. There has been some support for valence as significantly adding to the predictability of occupational preference, while other studies have indicated that instrumentality ratings alone are sufficient.     

The propensity to recall another's completed and uncompleted tasks as a consequence of varying social relationships

Two laboratory experiments are reported. Each investigates the bias that social relationships exert on a subject's propensity to recall another's completed and uncompleted tasks. Using closed circuit television, subjects in both experiments observed a bogus other working on a set of puzzles. The person working completed only one-half of the puzzles. In three of the six experimental conditions in both experiments, subjects believed that the remaining puzzles could be completed at a later time. In the first experiment, a subject's relationship to the other was determined by cooperative, competitive, or individualistic economic incentives. In the second, the relationship was determined simply by their similarity or dissimilarity on a bogus personality test. Utilizing a combination of Lewinian assumptions and contemporary theory about memory, we hypothesized that the opportunity to resume work would result in an increased propensity to recall uncompleted tasks in the competitive (or dissimilar) conditions and a decreased propensity to do so in the cooperative (or similar) conditions. Results confirmed this hypothesis. Additional data in both experiments suggest that subjects' relationships with the bogus other altered the accessibility of this information. Theoretical implications of these findings and their relationship to research on prosocial behavior are discussed.     

Static and dynamic factors in the perception of rotary motion

Direction of rotation and static slant judgments were collected for a series of outline plane forms in four experiments with 106 subjects. Direction was judged more accurately for forms displaying the same perspective gradients as trapezoids, but with right-angled contours, than for trapezoids. There were no consistent differences among these forms in judged slant. Direction of rotation judgments were affected by a static false interposition cue, with interposition increasing the proportion of veridical judgments when placed in conflict with a relative size gradient and decreasing this proportion when a size gradient was absent. Both a dynamic factor (contour angle change) and a static factor (misperceived relative distance of the vertical sides) were found to affect perceived direction of rotation, with direction judgments based primarily on the dynamic factor.     

Effects of level of arousal and type of task on bilateral skin conductance asymmetry and conjugate lateral eye movements

Several recent studies have indicated that the degree and direction of bilateral skin conductance (BSC) asymmetry and the direction of conjugate lateral eye movements (CLEMs) both index hemispheric functioning. Evidence also suggests that BSC asymmetry decreases and CLEMs become more unidirectional as level of arousal increases. Thirty-two normal adults received an habituation series of five-second tones followed by 40 questions. All stimuli were tape recorded. The questions (Schwartz, Davidson, and Maer, 1975) were grouped in four series: 10 verbal-emotional, 10 verbalnonemotional, 10 spatial-emotional, and 10 spatial-nonemotional. The order in which the four series were presented was counterbalanced across subjects. Prior to each question, subjects fixated the face of a mannequin. Sixteen subjects (high arousal) had five seconds to contemplate their answer; the remaining 16 (low arousal) had 10 seconds. Instructions for the high arousal group specified that intelligence and problem-solving ability was being tested, and that speed and accuracy were very important. Those for the low arousal group indicated casually that subjects were to ponder a series of questions. BSC levels, SC response amplitudes, and CLEMs were measured during a five-second interval following each tone or question. BSC levels were greater under the High Arousal condition. While approximately two-thirds of the subjects showed BSC asymmetry (roughly evenly divided between those with larger left and right hand responses), neither the degree nor direction of the asymmetries changed as a function of question type. While CLEM direction was more sensitive to question type under low arousal, (i.e., verbal questions resulted in predominantly right-going CLEMs and spatial questions resulted in predominantly left-going CLEMs) they tended to be stereotyped (i.e., unidirectional) under high arousal. Finally, no relationship was observed between CLEM direction and BSC asymmetry under either high or low arousal condition.     

Some promising dimensions for behavioral community technology

In recent years, the search for effective and replicable approaches to planned change in communities has escalated. Applied behavior analysts have participated in these efforts to remedy existing community problems and to increase the capacities of community residents to meet their goals. Examples of behavioral technologies for community settings are described and their advantages are noted. Criteria for more contextually appropriate community technologies are suggested and strategies for developing behavioral methods according to these criteria are described. This paper outlines some promising dimensions for behavioral community technology and discusses several possible limitations to a behavioral approach to addressing societal problems.     

On Using a Cancer Center Cancer Registry to Identify Newly Affected Women Eligible for Hereditary Breast Cancer Syndrome Testing: Practical Considerations

The goals of this research were to describe the process of identifying and recruiting individuals registered with a cancer center's cancer registry who were eligible to participate in cancer genetic research. This study specifically focused on younger women with personal and family cancer histories strongly suggestive of hereditary breast cancer syndromes, as determined by genetic counselor review. Of special interest was to determine the proportion of women from minority backgrounds who were (a) identifiable in this manner and (b) interested in genetic testing for hereditary breast cancer through a family cancer clinical research program. An initial query of the 292 cases of women newly affected with breast cancer and contained within the registry indicated that 124 met demographic eligibility criteria. The personal and family cancer histories of each of these women were then reviewed by a genetic counselor and the remaining, eligible patients (n = 31) were subsequently contacted by mail and telephone: approximately three-fifths (18/31) of these patients were White and two-fifths (13/31) were Black or of another racial background. Of the women who were sent one or more study-related mailings, 10% (3/31) were unreachable by telephone due to incorrect contact information, 32% (10/31) were reachable by telephone but unresponsive to messages left, 26% (8/31) had already participated in the family cancer program (i.e., were positive controls), 6% (2/31) were interested in participating in the program, 23% (7/31) were uninterested in participating in the program, and 3% (1/31) were later determined to be ineligible. Comparing the racial backgrounds of women who were either positive controls or interested in participating (i.e., “tester” category) to women who were either unreachable, nonresponsive, uninterested, or ineligible (i.e., “nontester” category), there was a nonsignificant trend for more non-White women to fall into the nontester than tester category, Fisher's Exact Test = .09. This work underscores practical steps in planning and carrying-out cancer genetic testing research among women newly affected with breast cancer and members of special populations. It also underscores the role that genetic counseling professionals play in this process.
