The nonverbal manifestations of cognitive processes in clinical listening

Nonverbal behaviors were observed during communicative sequences in videotaped clinical interviews. The interviews were conducted by two groups of physicians-in-training with contrasting cognitive profiles as determined by well-known laboratory tasks prior to the interviews. In each phase of the communicative sequences, significant differences emerged between the two groups for various types of nonverbal behaviors. Differences also emerged between the two groups of interviewers in their questioning patterns and in the nature of the narrative elicited from their interlocutors. A correlational analysis revealed consistent patterns of behaviors across phases of the communicative sequences. The findings provide additional evidence for the intimate connection between nonverbal behavior and cognitive activity and point to nonverbal behaviors as objective measures of the processes underlying clinical listening.     

Spatial and temporal relations in conditioned reinforcement and observing behavior

In Experiment 1, depressing one perch produced stimuli indicating which of two keys, if pecked, could produce food (spatial information) and depressing the other perch produced stimuli indicating whether a variable-interval or an extinction schedule was operating (temporal information). The pigeons increased the time they spent depressing the perch that produced the temporal information but did not increase the time they spent depressing the perch that produced the spatial information. In Experiment 2, pigeons that were allowed to produce combined spatial and temporal information did not acquire the perch pressing any faster or maintain it at a higher level than pigeons allowed to produce only temporal information. Later, when perching produced only spatial information, the time spent depressing the perch eventually declined. The results are not those implied by the statement that information concerning biologically important events is reinforcing but are consistent with an interpretation in terms of the acquisition of reinforcing properties by a stimulus associated with a higher density of primary reinforcement.     

Coincidence of attention deficit disorder and atopic disorders in children: Empirical findings and hypothetical background

ADDH children are often reported to display signs of allergies to various substances and/or atopic (AT) symptoms (i.e., atopic eczema, hay fever, or asthma). Since, at least for a subgroup of these children, a common biological background for both ADD and atopy may be assumed that may involve brain catecholamines, our hypothesis was that in a group of AT children (mainly atopic eczema) signs of ADD should appear more often than in controls. Parental hyperactivity ratings revealed a significantly higher frequency of ADD symptoms in the AT group, and laboratory tests sensitive to attentional capacity and inhibitory functions showed poorer performance in the AT children, the findings being similar to those reported in hyperactives. Thus, our results add support to the assumption of a common predisposing factor for both AT and ADDH in a subgroup of children.

The effects of dichotomous and crossed social categorizations upon intergroup discrimination

The present study explores the effect of crossing social categorizations upon subsequent intergroup discrimination. In the simple categorization conditions, subjects were divided into groups either on an explicitly random basis or on the basis of a very trivial similarity. In the crossed categorization condition, these two categorizations were criss-crossed. After performing a perceptual estimation task, subjects had to evaluate the performance of the different groups in this task. Subsequently they had to evaluate the groups on general characteristics less directly related to task performance. There was significant intergroup discrimination favouring the own group in the two simple categorization conditions, but this discrimination was strongly reduced in the crossed categorization condition. This was true for both kinds of evaluations. Subjects of a no categorization condition exhibited no self-favouritism. The theoretical implications of the data are discussed.     

Soccer,rooms, and the quality of your life: Mood effects on judgments of satisfaction with life in general and with specific domains

Two studies on the impact of temporary moods on judgments of satisfaction with life in general and with specific life-domains are reported. It was hypothesized that individuals simplify the complex task of evaluating their life in general by referring to their mood at the time of judgment, but evaluate specific life-domains on the basis of domain-specific information. In accordance with this hypothesis, both studies demonstrated strong mood effects on judgments of general life-satisfaction but only weak and non-significant effects on judgments of specific domain-satisfactions. The findings are interpreted as supporting the hypothesis that affective states serve informative functions.     

Language and hand: The dimension of referential competence1

Kinesic and verbal performance data were collected for two groups of women college seniors chosen to represent extremes in a type of verbal ability termed here referential competence. This ability is conceptualized in terms of degree of integration of symbolic and ikonic representation systems, i.e., the strength of the symbol-referent links in semantic memory. A criterion measure of referential competence was developed using deviation of color naming from word-reading times on the Stroop Color-Word test. Referential competence was shown to be statistically as well as conceptually unrelated to both the standard verbal intelligence and fluency measures, and to cognitive style. During a five-minute videotaped monologue about a personal experience, persons high in referential competence produced verbal material which was specific, vivid, and objective; in contrast to the subjective and general material of the low referential group; and also produced approximately three times as many object-focused hand movements, linked to rhythm and intonation patterns of speech but largely without decipherable content. The results suggest that motor schema have a continuing intrinsic role in mature speech production, related to structure rather than content of language.
