The operant control of vocalization in the dog

Control over the vocal responses of three dogs was established using operant-conditioning procedures. Several points of interest were observed in the data. First, fixed-ratio schedules of reinforcement generated a vocal response topography which was similar in detail to that of a “motor” bar-nosing response. Second, vocal responding was brought under the control of external visual stimuli as a result of differential reinforcement. Third, good stimulus control was maintained on a multiple schedule containing a vocal-response component and a bar-response component. Fourth, the stimulus control on the multiple schedule transferred with minimal disruption to a chain schedule requiring a sequence of 10 bar responses followed by 10 vocal responses. Fifth, because vocal and bar responses are not mutually exclusive, concurrent responding tended to develop on the chain schedule.

These results were discussed with reference to the advisability of applying the terms operant and respondent to unconditioned behavior, and, particularly, to unconditioned verbal behavior.

     

The Good, the Bad, and the Ugly

The impact of the activation of positive and negative components of an ethnic stereotype on judgments of responsibility for both positive and negative stereotypic behaviors was considered. Overall, stereotype activation biased judgments in a stereotype-consistent manner, across both positive and negative scenarios. Generalization of these judgments to more global trait perceptions of the target was limited to the negative scenario. Results are discussed in terms of both the use of stereotypes as inferential shortcuts and in-group favoritism mechanisms.     

Dimensions of welsh identity

A multidimensional scaling procedure was used to explore the role of cultural background, language and geographical region in the process of Welsh identity. Welsh bilinguals and Welshmen who could speak only English made similarity judgments among stimulus people represented by all possible combinations of these three factors and the anchor stimulus MYSELF. The results showed that language spoken was the most important dimension of ethnic identity for both groups, with cultural background and geographical region playing subordinate roles. These findings were discussed in relation to similar research conducted in Canada.     

A game-based formal system for Ł∞

A formal system for , based on a game-theoretic analysis of the ukasiewicz prepositional connectives, is defined and proved to be complete. An Herbrand theorem for the predicate calculus (a variant of some work of Mostowski) and some corollaries relating to its axiomatizability are proved. The predicate calculus with equality is also considered.     

Handwriting as an operant

An apparatus was designed to monitor handwriting behavior. Two subjects were studied under various schedules of monetary reinforcement for handwriting. The different schedules engendered and maintained distinctive response patterns but the rates of sustained responding did not vary across schedules. The development of fixed-interval performance following continuous reinforcement resembled the same transition in lower animals. In one subject, availability of reading material interacted with the schedule to determine response pattern. It was suggested that handwriting may be a more appropriate response for the experimental analysis of human behavior than the more frequently used button-pushing or lever-pulling responses.     

Some experimental influences of lawyers' complicated questions on eyewitness confidence and accuracy

Eyewitness evidence and the confidence the eyewitness expresses in such evidence are crucial in many criminal trials. The present study is an examination of the influence of confusing questions often used by attorneys to examine witnesses in court. Participants viewed a videotaped incident and were questioned about the incident 1 week later. Half the participants were asked questions framed in a confusing form; the remaining half were asked the same questions in straightforward language. Confusing questions reduced the participant witnesses' accuracy and suppressed the confidence-accuracy relationships compared with the condition in which simple questions were asked. However, the number of absolutely sure responses was the same in both conditions, although these responses were almost always accurate in the simplified condition, whereas in the confusing question condition, accuracy was comparatively poor. This experiment demonstrates the importance of ensuring that lawyers ask witnesses simple, clear questions.     

Individual differences in spatial learning from computer-simulated environments

A multivariate study examined relationships between the following factors: paper-and-pencil assessments of verbal and spatial ability, ability to form an accurate spatial representation of a large real-world environment, gender, computer attitudes and experience, proficiency with the navigational interface of a virtual environment (VE), and the ability to acquire and transfer spatial knowledge from a VE. Psychometrically assessed spatial ability and proficiency with the navigational interface were found to make substantial contributions to individual differences in the ability to acquire spatial information from a VE. Gender influenced many VE-related tasks, primarily through its relationship with interface proficiency and spatial ability. Measures of spatial knowledge of a VE maze were highly predictive of subsequent performance in a similar real-world maze, suggesting that VEs can be useful for training people about real-world spaces.     

Performance appraisal process and system facets: relationship with contextual performance

Because appraisal-related interactions between supervisors and employees may influence more than task performance, the authors considered the potential effects of social and interpersonal processes in performance appraisal on contextual performance. They hypothesized that performance appraisal process and system facets were associated with employees' contextual performance as well as with their perceptions of appraisal accuracy. After controlling relevant variables, they found that appraisal process facets explained variance in contextual performance and perceived accuracy beyond that accounted for by the system facets. However, when the order of entry for the process and system variable sets was reversed, only for perceived appraisal accuracy, as hypothesized, did the system facets account for variance beyond that explained by the appraisal process facets.     

The animating body: psychoid substance as a mutual experience of psychosomatic disorder

Starting from Jung's hypothesis of 'the psychoid', the author suggests that the concept can be extended and understood as a dynamic, relational and interpersonal experience-especially in regressed analytic relations. The author then defines his use of the term 'animating body' as having to do with primitive animal imagery and with psychosomatic symptoms stemming from disturbed pre-verbal and pre-whole-object stages of development. A case of a borderline patient is presented, whose projective identifications into the analyst infected him with her psychosomatic disorder, with her internalized Oedipal confusion and necessarily induced a mutually similar animal dream symbolism. If these embodied countertransference experiences (of desperate merging and sickening identification) can be lived through (tolerated and survived), thought through and interpreted, then they can actually become enlivening and lead to a therapeutic psychosomatic co-ordination.
