Evidence against integration of spatial maps in humans: generality across real and virtual environments

A real-world open-field search task was implemented with humans as an analogue of Blaisdell and Cook’s (Anim Cogn 8:7–16, 2005) pigeon foraging task and Sturz, Bodily, and Katz’s (Anim Cogn 9:207–217, 2006) human virtual foraging task to 1) determine whether humans were capable of integrating independently learned spatial maps and 2) make explicit comparisons of mechanisms used by humans to navigate real and virtual environments. Participants searched for a hidden goal located in one of 16 bins arranged in a 4 × 4 grid. In Phase 1, the goal was hidden between two landmarks (blue T and red L). In Phase 2, the goal was hidden to the left and in front of a single landmark (blue T). Following training, goal-absent trials were conducted in which the red L from Phase 1 was presented alone. Bin choices during goal-absent trials assessed participants’ strategies: association (from Phase 1), generalization (from Phase 2), or integration (combination of Phase 1 and 2). Results were inconsistent with those obtained with pigeons but were consistent with those obtained with humans in a virtual environment. Specifically, during testing, participants did not integrate independently learned spatial maps but used a generalization strategy followed by a shift in search behavior away from the test landmark. These results were confirmed by a control condition in which a novel landmark was presented during testing. Results are consistent with the bulk of recent findings suggesting the use of alternative navigational strategies to cognitive mapping. Results also add to a growing body of literature suggesting that virtual environment approaches to the study of spatial learning and memory have external validity and that spatial mechanisms used by human participants in navigating virtual environments are similar to those used in navigating real-world environments.

Misattribution and social control in the children of god

This article argues that deviant religions use supposedly godly justifications for their punishment systems by establishing theologies in which members misattribute divine authority to leaders whom they relate to emotionally as to demanding parents. These misattributing theologies “sanctify” the harsh suffering that members often experience. Illustrations of the theoretical points come from texts published by the Children of God in its early period (the 1970s), supplemented by accounts given by two women who have left the group. Earlier versions of this paper were presented at academic conferences in Vancouver and Washington, D.C. Professor Kent's research was supported by a grant from the Social Sciences and Humanities Research Council of Canada.     

The Jenkins Activity Survey measure of type a and frustration-induced anger

The present study examined the physiological and self-report responses of Type A and B males, defined by the Jenkins Activity Survey (JAS), to an anger-inducing frustration manipulation. Subjects jointly performed a task with a confederate and either were or were not frustrated by the confederate in their attempt to gain a prize. Physiological and self-report measures indicated that the frustration manipulation generated anger, but there was no evidence that Type A subjects were more angered than Type B subjects. Such findings may reflect a weakness in the Jenkins Activity Survey for adequately measuring the hostility component of the Type A pattern.The research reported here was supported by a Biomedical Sciences Support Grant RRO 7037 to the second author.

Listening to Different Voices: Formation of Sanction Beliefs and Taxpaying Norms1

How do people form beliefs about sanctions and norms toward the legal system? Using data from a telephone survey with 1,200 Minnesota adult residents, we examine how income sources that provide an opportunity to avoid official detection shape the amount and sources of communication about IRS enforcement effectiveness. Individuals with economic exchanges that provide the opportunity to cheat without detection received significantly more information about tax issues and IRS enforcement, especially from co-workers. Although both family members and co-workers were major sources of tax information, individuals received more information about IRS enforcement effectiveness from co-workers than from family members. Communication with co-workers lowered the perceived likelihood of IRS detections for overstating deductions, lowered the perceived severity of informal sanctions for tax cheatings, and lowered the perceived fairness of tax laws and positive personal norms toward compliance with tax laws. In contrast, communication with family members enhanced the perceived fairness of tax laws and positive personal norms toward compliance with tax laws. These findings are interpreted in the framework of social comparison theory (Festinger, 1954). We discuss implications for the theory and research on the development of beliefs about enforcement systems and compliance with laws.     

CONTINGENT REINFORCEMENT OF ABSTINENCE WITH INDIVIDUALS ABUSING COCAINE AND MARIJUANA

Two males diagnosed with cocaine dependence received a behavioral intervention comprised of contingency management and the community reinforcement approach. During the initial phase of treatment, reinforcement was delivered contingent on submitting cocaine-free urine specimens. The community reinforcement approach involved two behavior therapy sessions each week. Almost complete cocaine abstinence was achieved, but regular marijuana use continued. During a second phase, reinforcement magnitude was reduced, but remained contingent on submitting cocaine-free specimens. Behavior therapy was reduced to once per week. Cocaine abstinence and regular marijuana use continued. Next, reinforcement was delivered contingent on submitting cocaine- and marijuana-free specimens. This modified contingency resulted in an abrupt increase in marijuana abstinence and maintenance of cocaine abstinence. One- and 5-month follow-ups indicated that cocaine abstinence continued, but marijuana smoking resumed. These results indicate that the behavioral intervention was efficacious in achieving abstinence from cocaine and marijuana; maintenance, however, was achieved for cocaine only.
