A CROSS-CULTURAL STUDY OF PSYCHOLOGICAL DIFFERENTIATION

A cross-cultural study of psychological differentiation of Canadian and Pakistani high school students was undertaken to examine the nature of psychological differentiation in relation to differences in age/grade, gender, and academic programs. The study involved 707 Canadian students from grades 6, 8, 10, and 12; and 349 Pakistani students from grades 8, 9, 10, and 12. The Group Embedded Figures Test was employed as a measure of the field-dependence-independence cognitive style. Analyses of data included two-way and three-way analyses of variance to determine the effects of grade, gender, and academic program upon GEFT scores. Differences in psychological differentiation between high school students in the two cultures were discussed in terms of Berry's eco-cultural model.     

PERCEPTION OF PICTORIAL SPACE BY BUSHMEN*

A new test for measuring the ability to perceive pictorial depth was used with children of two remote Bushman populations (!Xu and Kxoe), as well as with a sample of adult Bushmen drawn from these populations and a sample of urban Zulu children. The results show that subjects of apparently little sophistication are capable of perceiving depth when confronted with a ‘geometric’ figure. They also show surprising inter-group differences which cannot be easily explained by differences of environmental experience.     

Reactions to Patients' Self-or Chance-Blaming Attributions for Illnesses Having Varying Life-style Involvement

The effects of the perceived accuracy of attributions of self blame and chance blame were examined in the context of health care. Health practitioners ( N = 147) rated interviews in which patients made self-or chance-blaming attributions for diseases with high (heart attack, stroke), or low (cancer, arthritis) life-style involvement, or acidental injuries. Three discriminant analyses yielded p < .001. Self-blaming heart and stroke patients were rated as coping better and acting more appropriately and typically than chance blamers. Other self blamers were rated as more depressed, poorly adjusted, coping poorly, not accepting disability, needing counselling and information. Additionally, self-blaming accident victims were judged as more dependent, less likeable, and having poorer prognoses than chance blamers. Realistic self blame for life-style diseases did not lead to victimization, but other self-blaming patients were stigmatized and the adaptiveness of self blame as a coping strategy was unrecognized.     

The honeymoon effect in job performance: temporal increases in the predictive power of achievement motivation

Correlations between a job performance criterion and personality measures reflecting achievement motivation and an interpersonal orientation were examined at three points in time after completion of job training for a sample of airline reservations agents. Although correlations between the personality predictors and performance were small and nonsignificant for the 3-month period after beginning the job, by the end of 6 and 8 months a number of significant relationships had emerged. Implications for the utility of personality measures in selection and performance prediction are discussed.     

The width of the auditory filter in children

Because young children have poorer auditory temporal resolution than older children, they ought to have, according to the inverse relation between temporal and frequency resolution, narrower auditory filters than older children. Therefore, the auditory filters of two 6-year-olds, two 10-year-olds, and two adults were measured by having them detect a 400-ms sinusoid (500, 1000, or 3000 Hz) centered in a spectral notch in a band of noise. The signal power for 71% correct was determined as a function of notch width with the two-alternative, forced-choice procedure. The principal results showed a significant decrease in signal power with age and a significant interaction between age and notch width. The best-fitting parameters of a model of the auditory filter showed that the filter was significantly wider for the 6-year-olds than for the 10-year-olds or the adults.     

Observational learning of two visual discriminations by pigeons: a within-subjects design.

Pigeon's observational learning of successive visual discrimination was studied using within-subject comparisons of data from three experimental conditions. Two pairs of discriminative stimuli were used; each bird was exposed to two of the three experimental conditions, with different pairs of stimuli used in a given bird's two conditions. In one condition, observers were exposed to visual discriminative stimuli only. In a second condition, subjects were exposed to a randomly alternating sequence of two stimuli where the one that would subsequently be used as S+ was paired with the operation of the grain magazine. In a third experimental condition, subjects were exposed to the performance of a conspecific in the operant discrimination procedure. After exposures to conspecific performances, there was facilitation of discriminative learning, relative to that which followed exposures to stimulus and reinforcement sequences or exposures to stimulus sequences alone. Exposure to stimulus and food-delivery sequences enhanced performance relative to exposure to stimulus sequences alone. The differential effects of these three types of exposure were not attributable to order effects or to task difficulty; rather, they clearly were due to the type of exposure.     

The matching law applies to wagtails' foraging in the wild

Field data concerning the time budgets and foraging success of pied wagtails (Motacilla alba yarrelli, Gould) are reanalyzed. It is found that the data are well described by the generalized matching law, with a marked bias towards spending time on the territory. In this case matching is not the result of maximizing reward rate, but it remains possible that it results from an allocation of time that maximizes survival.     

The Social Relations Model: An integrative method for personality research

As outlined by Snyder and Ickes (1985), the study of personality can be undertaken using one of three research approaches dispositional, situational, and interactive We show how the Social Relations Model provides an integrative method to estimate simultaneously dispositional, situational, and interactive effects Reviewed are component approaches to the study of personality The Social Relations Model is shown to be a component model (a special case of generalizability theory) applied in a social interaction context In the model, dispositional, situational, and interactive effects are termed actor, partner, and relationship effects, respectively The Social Relations Model can be used to answer a number of important issues in personality research The model can be used to assess reliability, measure the validity of self-ratings, and validate self-report inventories The model requires special designs in winch each person interacts with multiple partners Empirical examples are presented in which social anxiety, sex role inventories, and self-disclosure are studied     

Some reflections on the two psychologies of love

The mainstream view of love is that it is a state that arises from people mutually reinforcing each other or providing benefits to each other Yet careful quantitative analyses of imaginative thought patterns of people in love or in a state of affiliative arousal reveal themes of dialogue, commitment, and harmony rather than of mutual benefits It is suggested that asking people about love leads them to give causal explanations for the state which psychologists have elaborated into the theory that love is a response to having one's needs met Imaginative experiences characteristic of the state of being in love on the other hand may be different because they are primarily right brain mediated and do not share in the causal, instrumental type of reasoning characteristic of left brain conscious thinking Such conceivably right brain mediated experiences in TATs are more closely associated than presumably left brain mediated self-reports are with such physiological measures as evoked scalp potentials, neurohormone concentrations, and immune functions A vew of love that takes both self-report (left brain) and fantasy (right brain) measures into account does a better job of predicting affiliative behavior than does a view that relies solely on one or the other of the two types of measures
