Putting yourself in the skin of a black avatar reduces implicit racial bias

Although it has been shown that immersive virtual reality (IVR) can be used to induce illusions of ownership over a virtual body (VB), information on whether this changes implicit interpersonal attitudes is meager. Here we demonstrate that embodiment of light-skinned participants in a dark-skinned VB significantly reduced implicit racial bias against dark-skinned people, in contrast to embodiment in light-skinned, purple-skinned or with no VB. 60 females participated in this between-groups experiment, with a VB substituting their own, with full-body visuomotor synchrony, reflected also in a virtual mirror. A racial Implicit Association Test (IAT) was administered at least three days prior to the experiment, and immediately after the IVR exposure. The change from pre- to post-experience IAT scores suggests that the dark-skinned embodied condition decreased implicit racial bias more than the other conditions. Thus, embodiment may change negative interpersonal attitudes and thus represent a powerful tool for exploring such fundamental psychological and societal phenomena.     

Some Relationships between Group Process and Mental Health Phenomena in Theory and Practice

Though the focus on interpersonal interaction is a powerful therapeutic factor in group therapy, traditional chemical dependency therapy groups generally fail to employ the interactional group orientation. An interactional approach can be effectively applied to alcoholics if the following guidelines are observed: (1) recovery is always accorded priority, (2) the patient accepts identification as an alcoholic, (3) anxiety is carefully modulated, (4) the proper distinction is made between what the alcoholic is and is not responsible for, (5) the therapist is thoroughly familiar with Alcoholics Anonymous language, steps, and traditions. It is important that therapists not permit misperceptions of A.A. to be used as therapy resistance and that they be able to harness the wisdom of A.A. for psychotherapeutic ends. Group therapists must also be prepared to deal with common themes arising in the treatment of the alcoholic patient: idealization, devaluation, externalization, defiance, grandiosity, conning, and avoidance.     

In search of a surrogate for touch: The effect of haptic imagery on perceived ownership

Previous research has shown that individuals value objects more highly if they own them, a finding commonly known as the endowment effect. In fact, simply touching an object can create a perception of ownership that produces the endowment effect. In this paper, we extend this line of research in several ways. First, we show that haptic imagery, or imagining touching an object, can have the same effect on perceived ownership as physical touch. We then demonstrate that haptic imagery can lead to perceptions of physical control, which in turn increase feelings of ownership. Moreover, the more vivid the haptic imagery, the greater the perception of control and the feeling of ownership. Implications for theory and practice are discussed.     

Comprehensive community-based education and neurorehabilitation for children and adolescents with traumatic brain injury

Children and adolescents who experience a traumatic brain injury (TBI) typically have sensory, cognitive, behavioral, and functional skill challenges that must be addressed in acute and post-acute rehabilitation settings. This article describes a community-based school that combines educational, medical, nursing, family, residential-living, and psychological services in a comprehensive program of pediatric neurorehabilitation. The operational, administrative, and clinical features of these service components are presented. A critical aspect of the program is an emphasis on applied behavior analysis procedures for purposes of assessment, treatment formulation, and evaluation. Data are reviewed to demonstrate demographics, patterns of service delivery, and outcome. The school program represents an educational alternative for students with TBI who are discharged from acute-care settings and require comprehensive support services to facilitate their transition and re-entry to public school and community living. © 1998 John Wiley & Sons, Ltd.     

Flexibility and variability: Essential to human cognition and the study of human cognition

Traditional theories of cognition concentrate on the problem of stability, how it is that people perform the same cognitive act over and over despite different task pressures and varying circumstances. We suggest a different approach that focuses on the flexible and the inventive. From a dynamic systems perspective, intelligence is the adaptive flexibility that integrates the stability of past experience with the idiosyncrasies of the moment. In this paper we demonstrate the value of this perspective in the context of children's novel noun generalizations. We describe D-ALA, a dynamic systems model that embodies the principles of the account and use this model to explain the findings of three different experiments that show how young children flexibly and smartly adapt to novel circumstances in the task of learning new words.     

Determinants of instrumental extinction in terrestrial toads (Bufo arenarum)

Previous research in a water-reinforced instrumental training situation with toads (Bufo arenarum) has shown that performance in both acquisition and extinction is poorer after partial, rather than continuous reinforcement training. In Experiment 1, the performance of a group receiving 24 trials on a 50% partial reinforcement schedule was poorer in acquisition and extinction than that of continuously reinforced groups matched for trials or reinforcements. However, partially reinforced toads extinguished at the same rapid rate as a continuously reinforced group that received training only on the days in which the partial toads received water reinforcement. In Experiment 2, extinction was faster after 10 reinforced acquisition trials than after 30 trials. This evidence suggests that the deleterious effects of partial reinforcement in toads can be explained by a combination of two factors, namely, the distribution of reinforced trials across days and the total number of reinforcements.     

Blending qualitative and behavior analytic research methods to evaluate outcomes in inclusive schools

Following Haring's (1992) recommendation, we have utilized qualitative research techniques to assist us in designing a program of research on inclusive education which is responsive to the outcome values and priorities identified by teachers and parents. Using interviews, observations, and document analysis to follow 35 children in full inclusion classrooms over a period of two years, we have described outcomes for these children in three major domains. These outcome domains, and subthemes within them, have been evaluated and revised based on interviews and social validation ratings by parents and teachers. Dependent measures based on our qualitative research findings are currently being used in a series of behavior analytic studies designed to evaluate the effects of specific interventions on outcomes of inclusion for children with and without disabilities.
