Acquisition of locational information about reference points during blindfolded and sighted locomotion: Effects of a concurrent task and locomotion paths

Acquisition of cognitive maps (locational information about reference points) was investigated by requiring subjects to walk repeatedly according to paths consisting of 2, 4 and 6 linear segments. The starting point of each path was designated as a reference point, to which direction and distance were estimated by the subjects at the end of the path. Acquisition was indicated by the finding that variable errors and latencies decreased across blocks of trials. Interfering with central processing of locational information during locomotion by means of a concurrent task, while impairing orientation performance, did not seem to prevent acquisition. As suggested by an increase in latencies with the number of path segments, the subjects performing the concurrent task may have been able to infer and store the location of the starting point after walking. Finally, orientation performance did not improve for blindfolded subjects, probably because they were unable to use stored information about locations.     

Retroactive interference in single-cue probability learning

Abstract.— When two single-cue probability learning tasks with different amounts of unpredictable variance were learned in succession. a low variance task interfered with the retention of a high variance task, but the opposite was not true. The effects were positive in that they enabled the subjects to reach a higher response consistency and, thus, a higher level of achievement. It was suggested that the subjects made use of the low variance task to reject incorrect hypotheses about the cue-criterion relation and that interference from an interpolated task occurs only when this task provides information which has functional value for the subject.     

Affective Forecasting: Predicting and Experiencing Satisfaction With Public Transportation1

Affective forecasting in public transport was investigated in 2 studies. Study 1 revealed differences in satisfaction between users (n = 870) and non‐users (n = 137). Users were more satisfied than were non‐users with regard to reliability and safety, as well as with regard to overall satisfaction. It was also found that non‐users mispredicted their satisfaction with public transport. Study 2 revealed that habitual car users (n = 106) reported greater satisfaction after using public transport for 1 month than they had predicted initially, which provided additional support for the hypothesis that habitual car users would mispredict their satisfaction with public transport. Satisfaction with public transport also increased in comparison with a random sample of car users (n = 63).     

Memory dysfunction in mild aphasics

The effect of mild aphasia ( n = 9), as a result of subarachnoid haemorrhage (SAH), was evaluated against one matched (sex, age, and education) control group suffering from SAH of unknown origin without aphasia, and against one matched healthy control group. According to aphasia testing (Reinvang & Engvik, 1980), criteria for a classical diagnosis were not met. Therefore, the patients were characterized as mild aphasics: They generally displayed intact audo-verbal comprehension and repetition abilities, and they demonstrated a fluent, spontaneous speech. However, they showed phonemic and semantic paraphasias, with self-corrections; a few patients displayed alexia and agraphia. Memory performance of these three groups was evaluated by a neuropsychological test battery, designed to tap various components of verbal memory function. From the results it was concluded that: (a) Short-term memory is impaired, as regards the phonological loop and the central executive in working memory, whereas maintenance rehearsal is unaffected, given that the demands on phonological coding is minimized, (b) long-term memory is also generally impaired, whereas long-term learning and forgetting by means of subject-performed tasks proceeds within a normal range. Impairments were hypothesized to reflect less efficient central executive functions of working memory, involving generation of less appropriate semantic codes and phonological representations, (c) mildy aphasic patients are not subjectively aware of their own memory deficits, and (d) aphasia classification by means of standard procedures do not sufficiently characterize the nature of a mildy aphasic patient's memory problems.     

PPS director: administrator or counselor educator?

What is the primary role of the director of pupil personnel services? Is he a general administrator or a counselor educator? The author of this article feels that there is a great need for more directors who are oriented toward counselor education, and he focuses on three areas in which this type of director can have a great impact on school counseling.     

Teacher rated problems and school ability tests in relation to preschool problems and parents'' health information at school start. A study of first-graders

The reliability of assessments at four and six years of age in identifying teacher rated problems in behaviour, concentration, motor skill and school achievement was investigated in a study of first-graders. Relationships between preschool data and school ability tests, and between parents' information at school start and teacher ratings were also studied. Problems noted in preschool and school were often present in more than one area. Multiple problems at four and six years were strong predictors of later school problems, but preschool assessments of separate areas could not in general predict problems in corresponding areas in school. However, cross situational concentration deficits at the age of six did reliably identify concentration problems in the first grade, at the age of seven.     

Acquisition of locational information about reference points during locomotion with and without a concurrent task: Effects of number of reference points

Maintenance of orientation relative to reference points along a locomotion path and acquisition of locational information about these reference points were investigated by requiring subjects with and without a concurrent backwards counting task to walk in alleys and estimate direction and distance to the reference points when stopped. One or three reference points were presented on each trial in different groups of subjects. Acquisition of locational information was indicated by decreased latencies and variable errors with repeated exposure to the same locomotion path. Neither the larger number of reference points nor the concurrent task seemed to affect acquisition, but both lead to increased latencies indicating that the subjects under these conditions were unable to keep track of the locations of the reference points whilst walking. However, they may still have been able to infer these locations after the locomotion path had been traversed.     

Social competence as a predictor of chronic interpersonal stress

This 1-year prospective study tested Segrin and Abramson's (1994) social skills-stress hypothesis in a community sample of 137 late-adolescent females. The study found that self-reported interpersonal competence at initial evaluation predicted a significant proportion of the variance in chronic interpersonal stress 1 year later, even when prior chronic interpersonal stress and concurrent psychopathology were controlled. Exploratory analyses suggested that deficiencies in the ability to provide emotional support to others may function as a risk factor for the generation of interpersonal stress. These results provide support for theories (e.g., Hammen, 1991b) that emphasize a bidirectional causal relationship between stress and psychological adjustment.     

Goal Commitment and Performance: An Empirical Study Incorporating Role‐Stress Literature to Reveal Functional and Dysfunctional Influences

This study integrates the goal‐commitment and role‐stress literatures in a model to reveal functional and dysfunctional influences of goal commitment on role performance. In a sample of headmasters, we found empirical support for a role‐clarifying process suggesting that high commitment reduces role ambiguity and is ultimately positive for role performance. Our model also supports the dysfunctional effect of commitment through a role‐complicating process in which commitment drives role overload, which is negative for role performance. By including self‐efficacy in our model, we were better able to understand the positive and negative experiences of highly committed individuals. Contributing to the existing literature on role stressors, this study's results indicate that self‐efficacy mediates the influences of role stressors on role performance.     

Minority teachers become minority counselors

A high school district has developed an in-service counselor education program for minority teachers to help meet its need for more counselors who, by virtue of skin color, language, or inner city origins, have advantages in relating to minority students. One major component of the program is an in-service counseling practicum in which the teachers are supervised while they work with inner city students.
