The effects of behavior rehearsal and feedback on the acquisition of problem-solving skills in distressed and nondistressed couples

Couples who were paid to participate in an experimental marital enrichment program were randomly assigned to one of four treatment conditions or to a control group. All groups received training in solving marital problems, but the groups differed according to how they were trained; some received feedback (FB) on their previous taped performances, some had the opportunity to practice the skills suggested by the therapist (BR), some had both (complete treatment), and some simply were presented with instructions. Changes in problem-solving skills were assessed by behavioral observations of the frequency of positive problem-solving behavior before and after treatment, and global ratings of problem-solving effectiveness made by trained raters. In general, the complete treatment condition produced greater changes from pre- to post-test than any other condition. Couples in this condition showed significantly greater increases in positive behavior than any other group, and on global ratings of problem-solving skills they evidenced the greatest improvement, although on this measure they did not improve significantly more than BR couples.     

A deletion ahead of its time

An alleged defect in transformational treatment of syntax acquisition is the absence from child speech of certain predicted errors with ‘wh-’ constructions. In this paper, a theory of acquisition dynamics and intensive longitudinal data are brought to bear on this issue. The key observations involve an early precursor, at 24—28 months, of the relative clause. The analysis sheds light on two fundamental issues in transformational acquisition theory: The permissibility of simultaneous rule changes and whether a transformation can be acquired before the associated deep structure. The issues and analysis can be translated into non-transformational terms.     

Children's cognitive maps of large-scale spaces: Effects of exploration,direction, and repeated experience

Kindergarteners and third graders (mean ages 5–10 and 8–9 years) repeatedly encountered a model town and then constructed the town from memory. In Experiment 1, the effect of different types of exploration on the development of a cognitive map was assessed. Children who were directed to walk within the town placed buildings more accurately than children who had walked along the town's perimeter. Children who walked within the town and were directed to the spatial relationships among buildings had the highest placement accuracy. Third graders were more accurate than kindergarteners across the three types of exploration. In Experiment 2, children were permitted to explore the town alone for an unlimited amount of time. Under these conditions, third graders still placed buildings more accurately than kindergarteners. A comparison of Experiments 1 and 2 indicated that children developed more accurate cognitive maps when motor activity and attention were directed by the experimenter as opposed to being directed by the child. Accuracy improved with repeated walks and constructions in both experiments, and the results of Experiment 3 suggested that constructing facilitated the development of the cognitive map as much as walking. It was concluded that third graders' cognitive maps were more accurate than kindergarteners' maps due to differences in the speed of acquisition and storage of spatial information.     

Visual tracking in young infants: Evidence for object identity or object permanence?

Previous research has shown that 5-month-old infants visually anticipate a moving object's appearance after it disappears behind a screen. This experiment assesses the underlying basis for such anticipatory tracking. Three tracking tasks were presented to 5- and 9-month-old infants. In the Permanence task, the object's continuous existence was apparently violated while it was behind a screen. In the Feature and Trajectory tasks, the object's features or trajectory changed while behind the screen. Disruptions in the infant's smooth visual pursuit of the object were recorded. Five-mont-olds showed disruptions of visual tracking in the Feature and Trajectory tasks, but not in the Permanence task. The tracking of the 9-month-olds was disrupted in all three tasks. We conclude that both 5- and 9-month-olds possess rules specifying the identity of a moving object which is occluded. For 5-month-olds these rules are based upon the object's features and trajectory, but not upon a concept of object permanence. For 9-month-olds all three rules—feature, trajectory, and permanence—are utilized in visual tracking.     

Impression management in the forced compliance situation: Two studies using the bogus pipeline

Two studies were performed to assess the interpersonal concerns of subjects in the forced compliance paradigm. The first study counterposed dissonance and impression management theory predictions in a 2 × 2 design by varying the public versus private nature of the counterattitudinal behavior and by assessing attitudes with the usual pencil-and-paper method or with a bogus pipeline technique designed to create strong pressures toward sincere reporting. Attitude change occurred only in the Public/Pencil-and-Paper condition and thus supported an interpersonal or impression management interpretation. The second study examined the effect of measuring the critical attitude a second time in the mode not experienced in the first assessment. This three-group design (Pencil-and-Paper/Bogus Pipeline, Bogus Pipeline/Pencil-and-Paper, Control) demonstrated that attitude change occurred only in the Pencil-and-Paper/Bogus Pipeline condition and was maintained on the second assessment when measured by the bogus pipeline. A common-factor analysis of the secondary measures in the second study demonstrated that the Pencil-and-Paper/Bogus Pipeline subjects reported a great deal of negative arousal such as embarrassment and guilt, while the subjects in the Bogus Pipeline/Pencil-and-Paper condition reported feeling manipulated and constrained. The findings of both studies were interpreted as consistent with impression management theory.     

Distraction and social comparison as mediators of social facilitation effects

Sanders and Baron (Journal of Personality and Social Psychology, 1975, 32, 956–963) suggested that increases in drive produced by the presence of others (social facilitation) are due to the tendency for others to distract task performers as they worked on a task. This Distraction-Conflict theory proposes that socially mediated drive induction will occur whenever there is some reason to shift attention from the task to the social stimuli. In the case of humans, one such reason may be the opportunity to obtain social comparison information from an audience or coactors. The present research demonstrated that social facilitation effects (improved simple task performance and impaired complex task performance produced by the presence of others) occurred only when subjects were motivated to obtain comparison information (Experiment I) and when comparison information was available (Experiment II). The availability of comparison information also led to increased accuracy in estimating the coactor's performance. This indicated that in conditions manifesting social facilitation, subjects were spending some time monitoring the coactor's work, which is an inherently distracting activity. Several supplementary measures of distraction were generally consistent in indicating greater distraction under conditions manifesting social facilitation. The present results offer no support for the explanations of social facilitation suggested by Zajonc and by Cottrell.     

Generational differences in work values between parents and children and between boys and girls across grade levels 6, 9, 10, and 12

A cross-sectional comparison of school children in grades 6, 9, 10, and 12 and their parents was made to examine changes in work values and the relationship between children's and their parents' work values as a function of age and sex. Discriminant function analyses revealed support for hypothesized differences in children's values and for the convergence of sex differences in values at later ages. Results also confirmed that at earlier ages there is greater similarity in values between children and their like-sexed parent but older (grade 12) boys and girls are most similar to their fathers. These findings confirm and expand the results of earlier research.     

Organization of short-term verbal memory in language areas of human cortex: Evidence from electrical stimulation

Short-term verbal memory (STVM) performance was measured during electrical stimulation of human left frontal-parietal-temporal cortex, at craniotomy under local anesthesia for the treatment of medically intractable epilepsy. The areas of cortex where stimulation alters language, as measured by object naming, are separate but adjacent to the areas where stimulation alters STVM. There are differential effects of stimulation during input, storage, and output phases of STVM at different cortical sites. These suggest that cortex adjacent to the posterior language area is a site of storage of STVM, while cortex adjacent to anterior language area is involved in retrieval from STVM.     

Language localization and variability

Language localization data from 11 neurosurgical patients undergoing cortical resection for medically intractable focal epilepsy were obtained by mapping with bipolar electrical stimulation at current levels below sensory and after-discharge thresholds, during an object-naming task. The topographical extent of language cortex in an individual subject can be wider than that proposed in the classic maps. Within this zone, language is discretely localized, with different sites variably committed to language as measured by the naming function. The naming data from the left cortex of eight patients, all left-brain-dominant, were pooled to determine the variability within the primary language zone. Only a narrow band of posterior, inferior frontal lobe, immediately anterior to motor strip, showed involvement in all of the patients in whom it was sampled. This is a motor speech area; it constitutes only a small portion of the frontal language area. Other infero-frontal, parietal, and postero-temporal sites showed considerable variability, with naming involvement in only 50–80% of the patients sampled. There is a suggestion that some of these patterns of language localization may correlate with poorer verbal abilities. Data were also obtained on language localization in the left insula in a patient who was left-hemisphere-dominant for language. Mapping of the right hemisphere in a left-brain-dominant patient demonstrated no naming function. Mapping of the right hemisphere in one and the left hemisphere in another patient, both of whom were right-hemisphere-dominant for language, suggests more diffuse language representation with right hemisphere dominance.
