A plea for more intervision

The author presents an argument for tolerance, mutual understanding and reconciliation in psychotherapy, instead of a continued emphasis of schools. Psychotherapists' work with clients is proposed as a likely area for mutual understanding, rather than continued emphasis on their particular theories and academic matters. Psychotherapeutic intervision groups in which a small number of therapists voluntarily discuss their cases with peers from various backgrounds have become increasingly common again in recent years.Slightly revised version of a presentation made at the Georgetown Family Center Symposium in November 1995.     

Role of optical flow field asymmetry in the perception of heading during linear motion

During linear translation through a stationary environment, the pattern of optical flow generated on each retina is symmetrical when the head is aligned with the heading, but during lateral gaze the optical flow is asymmetric. We assessed whether human subjects could use the magnitude of this asymmetry to determine the direction of heading during passive translation through a 3-D environment. When allowed to move their heads in order to look in the direction of self-motion, subjects indicated their heading precisely and accurately. When the head was locked in alignment with the misaligned body, and gaze adjustments were not allowed, responses were quite precise, but showed a large bias which increased with increasing heading angle.     

The effect of serving as a model of self-control on subsequent resistance to deviation in children

The effect of having a child serve as a rule-following model for other children on the model's own subsequent rule-following was investigated in a resistance to deviation situation. First- and second-grade boys (age range 73 to 94 months) who were told they would serve as self-controlling models for others and who actually served in this capacity touched prohibited toys less than did boys who were not told they would serve as models. Boys told they were to serve as models but who were prevented from performing deviated at a level between the models and boys given no responsibility. Having children serve as rule-following models for others is suggested as an effective, non-punitive technique to increase their self-control.     

The extinction of within-compound flavor associations

Three experiments studied extinction of the associations which are formed between two flavors presented in a simultaneous compound. In Experiment 1 those associations were identified by a sensory preconditioning procedure in which the poisoning of one element of the compound led to the rejection of the other element. Separate presentation of either element between their joint occurence and the poisoning of one element sharply attenuated the rejection of the other element. That attenuation was interpreted in terms of the extinction of within-compound associations. Experiment 2 obtained similar results with an alternative extinction procedure in which the elements of the original compound were presented in other compounds. Experiment 3 obtained similar results when the existence of the within-compound associations was determined by an alternative assessment procedure in which one element of the compound was made more attractive by the induction of a specific hunger. These experiments suggest that within-compound associations can be extinguished when the elements are separately presented outside of the compound. Experiments 2 and 3 make less plausible an alternative interpretation of the effects of separate element presentation in terms of reduction of the novelty of the element. The findings may be taken as implying that the elements of a simultaneously presented compound are joined by a single symmetrical association which acts at various points during a sensory preconditioning experiment.     

Reality therapy: Icing on the cake of behavior modification

The paper presents a conceptual model for therapeutic intervention based on a behavioral orientation. Behavioral therapy is viewed on a continuum ranging from basic operant techniques to cognitive strategies applied to human interaction. It is hypothesized that the elements of reality therapy, with its emphasis on human interaction, are needed to provide closure to the therapeutic intervention and to help maintain new coping behaviors. Utilizing the context of an institutionalized client, suggestions for how this process might occur are discussed.
