Empirically Unbinding the Double Bind: Review of Research and Conceptual Reformulations

This article reviews the empirical research on the double-bind concept and describes the conceptual and methodological limitations of the studies. Because of the difficulty in defining and operationalizing the concept, most studies have not adequately tested substantive issues related to the double-bind hypothesis. The relationship of the concept to other family dynamics concepts is discussed and a reformulation of some of the basic tenets are presented. The article also attempts to clarify several of the theoretical and methodological issues related to the double-bind hypothesis, and specific recommendations are made regarding future research on this topic.     

Men's sociosexuality is sensitive to changes in mate availability

Correlational research has linked mate availability to human sexual behavior, whereby unrestricted sociosexuality seems to be most common under conditions of female abundance. In this study, 71 heterosexual men were randomly assigned to one of two mate availability priming conditions, mate scarcity or mate abundance, and subsequently completed measures of sociosexuality as well as infidelity intentions. Results indicated that men in the mate abundance condition reported stronger sociosexual attitudes and desires, and among those currently in relationships, stronger infidelity intentions. These findings were contrasted with those from a separate sample of 66 heterosexual undergraduate women. Mate scarcity had no effects on women's sociosexuality or infidelity intentions. Findings suggest that when mates are scarce, men will adopt a sociosexual orientation aimed at maintaining a single partner.     

Can men and women be just friends?

We tested evolution‐based hypotheses about (1) sex differences in perceived benefits and costs of opposite‐sex friendship and (2) differences in perceived benefits of same‐sex friendships and opposite‐sex friendships. In the Preliminary Study (N= 400), an act nomination procedure was used to identify the benefits and costs of same‐sex friendships and opposite‐sex friendships. In Study 1, a total of 231 participants (100 men, 131 women) evaluated the frequency of occurrence of 100 benefits and costs in their closest same‐sex friendship or opposite‐sex friendship. In Study 2, a total of 229 participants (92 men, 137 women) evaluated how beneficial and how costly each would be if it were to occur in their closest same‐sex friendship or opposite‐sex friendship. Results supported several key hypotheses. Men perceived sex with their opposite‐sex friends as more beneficial than did women. Women reported receiving protection from their opposite‐sex friends more often than did men, and they perceived the protection as highly beneficial. Both men and women reported receiving information from opposite‐sex friends about how to attract mates, and they perceived this information as beneficial. The discussion focuses on whether these benefits reflect an evolved psychology of opposite‐sex friendship, or instead are incidental by‐products.     

The Unbiased Mind: A Possible Resource for Medical Problems

The purpose of this pilot study was to explore the problem solving abilities of school‐aged children. The study took place at the summer day camp program at Howard Public School, in Etobicoke, Ontario. There were 15 children (6 boys, 9 girls) with a mean age at the time of testing of 5.1 years. A medical problem with a known solution (concept of a flow‐directed device to determine pulmonary wedge pressure) was presented to 15 children in the form of a children's story. The children were then asked to solve the problem by completing the story. A successful answer was taken to be any that suggested a flow‐directed device. The results showed that of the 15 children who read the story, four suggested flow‐directed methodologies. Other non‐practical, but creative, solutions were suggested. The findings suggest that by translating a previously solved medical problem into a simplistic children's story, preschoolers may provide a conceptual solution.     

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.
