Concurrent schedules: a quantitative relation between changeover behavior and its consequences

Data from several published experiments on concurrent variable-interval schedules were analyzed with respect to the effects of changeover delay on the time spent responding on a schedule before changing to an alternate schedule: i.e., the interchangeover time. Interchangeover time increases as the duration of the changeover delay increases, and the present analysis shows that a power function describes the relation. The power relation applied in spite of numerous differences in the experiments: different variable-interval schedules for the concurrent pairs; equal or unequal reinforcement rates for the schedules of the concurrent pairs; different durations of the changeover delay; response-dependent or response-independent reinforcers; pigeons or rats as subjects; different reinforcers. A power function also described the data in experiments where the changeover incurred a timeout, where a fixed ratio was required to changeover, and also when asymmetrical changeover delays were used.     

Role and justice considerations in the attribution of responsibility to a rape victim

This study was designed to assess the extent to which social role and “just world” considerations would affect perceptions and attributions of responsibility to a rape victim. The rape victim was either a topless-bottomless dancer, a social worker, or a Catholic nun, and she was either acquainted or unacquainted with her assailant. In the acquainted condition, the dancer was attributed the greatest and the nun the least amount of responsibility, indicating that social role factors can govern the range of attributional judgments which might be made in any given instance. However, unacquainted victims were ascribed more responsibility for the rape than were acquainted victims, a difference which was significant when the victim was the nun. The latter findings are discussed in terms of Lerner's just world hypothesis. Significant sex differences were found in subjects' perceptions of and responses to the rape incident and, contrary to earlier findings, no relationship was found between victim attractiveness and punitiveness toward the wrongdoer.     

Attribute coding at different levels of processing

Schoolchildren, aged 16 years showed poorer incidental learning for nouns if the orienting task was one of finding rhymes for the items compared to assigning each word to a semantic category. On a recognition task including homophone and synonym foils, rhyming subjects made significantly more phonemic errors, whereas categorizing subjects produced a significantly greater number of semantic confusions. Subjects instructed to construct images for each of the nouns showed a performance pattern similar to the categorizing group. The results are interpreted in terms of Herriot's (1974) view that different levels of processing are associated with the coding of different clusters of stimulus attributes.     

Jesuit Sensuality and Feminist Bodies

The stated goal of Donna Haraway's "Cyborg feminism" is to liberate sensuality from violence. In examining her book alongside that of Jesuit Toletus it becomes clear that both argue that sensuality is a place of metaphysical violence. The first two sections of the essay demonstrate this, and, in addition that Toletus' commentary on Aquinas is hardly accurate. This fact will help justify the claim that the Jesuit tradition includes a rather particular theory of sensuality, the origin of which is perhaps Giles of Rome. A third section shows how the Jesuit Gaston Fessard rediscovered Aquinas' own theory of sensuality through a thoroughgoing critique of Hegelian and Marxist dialectic. The essay concludes that Haraway would do well to adopt Aquinas' non-violent theory of sensuality as her own.     

Contributions of positive behavior support amid lingering questions over its relationship with behavior analysis: A review of Positive behavior supports for adults with disabilities in employment,community, and residential settings by Storey and Post

Positive Behavior Supports for Adults with Disabilities in Employment, Community, and Residential Settings by Keith Storey and Michal Post (2019) presents valuable information for support providers and clinicians working with adults in inclusive settings who display challenging behavior. Numerous examples of challenging behavior encountered in such settings are provided along with a multitude of interventions for addressing the behavior in ways that comport with the values of positive behavior support (PBS). This review highlights contributions of the Storey and Post book and considers the content in regard to the controversial relationship between PBS and applied behavior analysis (ABA). The authors specify ABA as the foundation of PBS, but questions linger about the exact PBS–ABA relationship that will likely affect the book's ultimate contribution. Concern over the relationship is illustrated in regard to qualifications of behavioral professionals whom the authors often refer to as being necessary to help support providers develop and implement PBS interventions.
