Mentalism, behavior-behavior relations, and a behavior-analytic view of the purposes of science

In a behavioral view, the purposes of science are primarily prediction and control. To the extent that a scientist embraces both of these as a unified and generally applicable criterion for science, certain philosophical and theoretical practices are counterproductive, including mentalism in both its metaphysical and metatheoretical forms. It is possible and often worthwhile to recast some mentalistic talk into an issue of behavior-behavior relations. When behavior-behavior relations are approached non-mechanistically, however, analysis cannot stop at the level of the relations themselves. Several analytic concepts common in the behavioral community share some of the dangers of mentalism if not employed properly, including such concepts as self-reinforcement, response-produced stimulation, and self-rules.     

The process of scapegoating in a neonatal nurses' group

This paper reviews the literature on scapegoating, elaborating on the underlying mechanisms before describing the process of scapegoating as it occurred in a neonatal nurse support group. Illustrative vignettes are used to discuss how scapegoating was used by group members to avoid painful feelings arising from their care of extremely ill infants. Group process is related to the stages of the group's development as feelings were addressed more directly and the need to use scapegoating as a defense decreased.     

Factors Perceived as Helpful by the Members of Self-Help Groups: An Exploratory Study

The factors perceived as helpful by members of three different types of self-help groups are examined, using the 12 factors identified by Yalom as operative in group psychotherapy. Questionnaires were given to 45 members of self-help groups, asking for their views of the most and least helpful aspects of their experiences of their group, and for their judgement of its effectiveness. Results indicated that members of a group concerned with social and personal support in the face of a socially problematic situation (widowhood) found the experience of Universality to be the most helpful factor, while Self-Disclosure was least helpful. Members from a group for the physically sick (asthma sufferers) also reported the least helpful factor to be Self-Disclosure, but said that the most helpful factor was Guidance. By contrast, the group concerned with providing 'therapy' for depressives reported Cohesiveness to be most helpful, and Guidance to be least helpful. Comparison with other studies using similar methodologies with different group populations suggests that the factors likely to be effective in self-help groups for the socially unsupported and physically sick on the one hand, and for the psychologically disturbed on the other, may differ.     

The accommodative response to subthreshold blur and to perceptual fading during the Troxler phenomenon

A study is reported which shows that accommodation can be stimulated by a blur stimulus which is below the threshold for visual perception. It is also shown that perceptual fading of the target, caused by stabilization of the retinal image (Troxler phenomenon), can eliminate the accommodative response causing it to default to its resting level. The first finding suggests a way in which the visual system can filter the percept of blur out of our conscious awareness and still effectively utilize the blur as a steady-state error for the accommodative control system. The second finding is consistent with a locus for the Troxler phenomenon in the early afferent part of the visual pathway, ie the retinal ganglion cells.     

Static depiction of movement

A number of pictorial devices were compared in order to assess their relative effectiveness in depicting events. Effectiveness, as measured by a rating task, did not seem to be a function of the classification of a device as natural or metaphorical. Rather, it depended on whether a given device highlighted a distinctive aspect of a particular event (running, jumping, or moving), or simply modified the event. This observation was buttressed by the existence in a forced-choice task of a category boundary for depictions of running (pictures with a certain device were seen as running, those without it were not) but not for moving or jumping. Even preschool children displayed some understanding of metaphorical devices. They chose figures with those devices as running faster than the experimental standard. Results are discussed in the context of Kennedy's characterization of pictorial metaphors and Gibson's framework for understanding the relationship between pictorial and environmental information.     

Modification of preschool sex-typed behaviors by participation in adult-structured activities

Earlier studies have shown the girls spend more time than boys in activities that are highly structured by adults. Structured activities may encourage feminine sex-typed behaviors such as compliance to adults; low-structure activities may encourage masculine sex-typed behaviors such as independence and assertiveness. In the present study the effects of high or low levels of adult structuring on children's social behavior during preschool free-play activities were tested in a field experiment carried out during an entire semester in one preschool classroom. For the first 15 minutes of free play, children were assigned to high- or low-structure activities. As predicted, when children were in high-structure activities, they exhibited high rates of bids for recognition and compliance to adults; in low-structure activities, they exhibited peer-directed leadership, bids for recognition, and compliance. There were no generalized effects of these treatments on their subsequent free choice of activities or social behavior. The study demonstrates powerful effects of naturally occurring variations in children's play activities on sex-typed social behaviors.
