On the role of reduced auditory feedback and kinesic self-stimulation during Stroop Color-Word Performance.

Feedback from one's own voice provides important vocal-motor cues for effective cognitive processing. Reduction of such feedback is known to disturb such functioning. Work in our laboratory has shown that kinesic self-stimulation also plays an important role in cognition, and appears to regulate the focusing of attention under conditions of distraction. The present study investigated the effects of both auditory feedback and kinesic self-stimulation in the regulation of cognitive interference during performance of the Stroop Color-Word Task. Twelve subjects were tested on the Stroop task under conditions of normal and occluded hearing. Kinesic self-stimulation and response errors during color-word performance were recorded on video tape. The findings indicated that not only did self-stimulation increase when voice feedback was reduced, but that this increase was associated with a reduction in specific types of color-word performance errors. Individual differences revealed that high kinesic responders made significantly fewer errors in task performance than did low kinesic responders. Results were interpreted as revealing a kinesic feedback mechanism which has adaptive significance in regard to self-editing when auditory feedback is reduced.

Schedule-induced kinesic and taxic behavioral stereotypy in the pigeon.

Two experiments explored the functional character of 2 schedule-induced interim behaviors (pacing and retreat) and 1 terminal behavior (keypecking) that developed on fixed-time (FT) schedules of food delivery with a keylight that increased in brightness throughout the interstimulus interval. In Experiment 1, this ramp procedure was compared with a less discriminable ramp, and FT and Random Time (RT) procedures without a signal. Decreased discriminability expanded keypecking in the trial. The FT schedule eliminated only keypecking and the RT procedure eliminated keypecking and retreat while pacing remained. In Experiment 2, predictive and unpredictive ramps were added to the RT procedure. The data suggest that schedule-induced stereotypy can be divided into kinesic stereotypy (pacing), which arises from repeated reinforcer presentations, and taxic stereotypy, which is tied to an increase (keypecking) or decrease (retreat) in the momentary probability of reinforcement.

[Kinesic paroxysmal familial choreoathetosis: presentation of a case].

Report of a case of kinesic paroxysmal choreoathetosis in a family (as far as we know the first case of a family on record in Spanish) which responded very well to treatment with low doses of carbamazepine. The characteristics of this infrequent clinical entity are also discussed.

Video-analytic study of manual kinesics and its lateralization in the course of treatment of depressive syndromes.

Video-taped interviews of 47, predominantly endogenous depressive in-patients, recorded on days 0 and 21 of pharmacotherapy were analysed with respect to frequency, duration and side-preference of defined hand movements. The data were related to clinical improvement or deterioration as assessed by judgement of the syndromal aspects: retardation and agitation. 1. Above all, improvement is marked by a decrease of Continuous body-focused movements (C) and an increase of Object-focused movements (O) of the speech primacy type (OS)-deterioration by an increase of C and decrease of OS. 2. The degree of retardation corresponds to O, the degree of agitation, above all to C. 3. O show no side-preference with a higher degree of retardation or agitation respectively, but a marked right perference with a lower degree of retardation or agitation, Discrete body touching (D) shows a left preference only, with a higher degree of retardation. A comparison of sidedness of O between interviews 1 and 2 shows no lateralization trend, either in the improvement or the deterioration group. In contrast, D changed from left weightiness to symmetry, coinciding with improvement but not with deterioration, With reference to the latter findings we discuss the possibility of a particular mode of cerebral lateralization predisposing to endogenous depression.
