Developmental and cross-situational stability in infant pigtailed macaque temperament

We assessed developmental stability and context generalizability of temperament in pigtailed macaques (Macaca nemestrina) from the University of Washington Infant Primate Research Lab. A principal components analysis condensed 6 behavioral measures into 2 components, interpreted as reactivity and boldness. Changes in these measures over the 1st 10 months of development showed a trend toward calmer and bolder behavior with age, with significant individual variation in the pattern of change. Boldness showed a quadratic pattern of change, whereas reactivity decreased linearly. We also studied the relationship between temperament and response to a novelty probe. The magnitude of the response to the novelty probe decreased slightly over time, and boldness and reactivity in a familiar setting did not predict these changes in response to novelty. In a 2nd principal components analysis, reactivity to novelty represented a distinct aspect of temperament. Our results demonstrate developmental changes and context dependency in macaque behavior.     

Neural coding of relational invariance in speech: human language analogs to the barn owl

The ability to form perceptual equivalence classes from variable input stimuli is common in both animals and humans. Neural circuitry that can disambiguate ambiguous stimuli to arrive at perceptual constancy has been documented in the barn owl's inferior colliculus where sound-source azimuth is signaled by interaural phase differences spanning the frequency spectrum of the sound wave. Extrapolating from the sound-localization system of the barn owl to human speech, 2 hypothetical models are offered to conceptualize the neural realization of relative invariance in (a) categorization of stop consonants/b, d, g/ across varying vowel contexts and (b) vowel identity across speakers. 2 computational algorithms employing real speech data were used to establish acoustic commonalities to form neural mappings representing phonemic equivalence classes in the form of functional arrays similar to those seen in the barn owl.     

Physical Attractiveness and Psychological Adjustment Among Substance Abuse Inpatients: A Longitudinal Study1

Relations between psychological adjustment and physical attractiveness were examined longitudinally in substance abuse inpatients, controlling for the effects of length of drug abuse, length of inpatient stay, age, and socioeconomic status. Measures of adjustment and attractiveness were obtained during the first week of admission and six weeks later (within two weeks of discharge). Regression analyses indicated that initial attractiveness did not predict later adjustment, and initial adjustment did not predict later attractiveness. Partial correlation analyses revealed a positive association between attractiveness and adjustment at the first time point, but not at the later time point. These results suggest that physical attractiveness exerts only a temporary effect on judgments of adjustment in an inpatient setting. Attractiveness may affect decisions made when screening patients at mental health facilities, but may not affect decisions made over the full course of inpatient treatment.     

Sex and sycophancy: Communication strategies for ascendance in same-sex and mixed-sex superior-subordinate dyads

The purpose of this study was to examine communication strategies for ascendance in same-sex and mixed-sex superior-subordinate dyads. The strategies, operationalized in terms of task and social facilitation, were derived from Bales' Interaction Process Analysis categories. Corollary data were collected relative to the subordinate's expected job satisfaction under male versus female supervision. Results indicated that (1) the perceived importance of task versus social facilitative strategies varied both within and across the four types of dyads, and (2) female subordinates expected to be more satisfied working under female supervision than did male subordinates.The authors would like to thank Ralph Kilmann and John Grant, Graduate School of Business, University of Pittsburgh, for their assistance in providing subjects for this study.     

Financial product sensitivity predicts financial health

Recent research has aimed to understand how people consider financial decisions because they have important consequences for well-being. Yet existing research has largely failed to examine how attitudes and behaviors vary as a function of the specific financial product (e.g., debt type). We ask to what extent people differentiate between similarly categorized financial products (e.g., debt or investment) as a function of their terms (e.g., interest costs and expected returns) and whether such differentiation predicts financial health. Across four studies, we find not only that there are individual differences in attitudes toward similar financial products (e.g., two distinct loans), but also that the extent to which a consumer is averse to high-cost versus low-cost products predicts financial health. This relationship cannot be fully explained by financial literacy, numeracy, or intertemporal discounting. In addition, nudging people toward differentiating between financial products promotes decisions that are aligned with financial health.     

The significance of psycho‐peristalsis and tears within the therapeutic relationship

This paper represents a heuristic study of the significance of involuntary, intuitive gut responses (psycho‐peristalsis) and tears within the therapeutic relationship. Autobiographical material and qualitative data were gathered from case‐notes and semi‐structured interviews with four client/co‐participants. Data on occurrences of psycho‐peristalsis and tears were collected from 92 clients seen within a six‐year period. Eleven elements of a ‘general constitutional structure of experience’ were identified. A central finding of the study concerns the gut's apparent ability to ‘pick up’, at an unconscious level, significant material that might otherwise have been overlooked. The research suggests some possible clues to the process of unconscious communication and healing, and adds an interesting psychological dimension to recent findings in the fields of neuroscience and cell biology which amount to the discovery of a ‘second brain’ in the walls of the small intestine. These phenomena are examined in the light of theoretical debates in counselling and psychotherapy.     

“I and thou”: Another barrier to societal change?

The purpose of this study was to examine cognitive barriers to the incorporation of information about societal discrimination against groups of which the individual is a member. Information about discrimination, personal efficacy, and the control of reality was presented to comparable groups of students enrolled in courses on women. Items were phrased either in terms of the self (first-person singular) or generically (in the third person). The results showed that individuals are more aware of discrimination against others than against themselves, and are more likely to attribute personal efficacy and control to themselves than to others. It is suggested that the differential use of identical information when applied to the self vs others is a cognitive mechanism that leads people to ignore evidence about sociostructural biases that affect themselves.
