Sequential effects in two-choice reaction time: Subjective expectancy and automatic after- effect at short response-stimulus intervals

Between three serial two-choice reaction-time tasks, the response-stimulus interval (RSI), stimulus-response compatibility, and practice were varied in order to examine two determinants of sequential effects — subjective expectancy and automatic aftereffect. It appears that subjective expectancy is absent when the RSI is below a critical minimum. In an incompatible task, however, this minimum is greater. This is interpreted in support of the single-channel hypothesis: the subject only builds up expectancies when the “central processor” is unoccupied. The automatic aftereffect increases as the RSI decreases. The decay of the aftereffect seems to take place mainly during the RSI and only to a minor degree during the reaction process. Normally, a strong aftereffect operates in a general way, but after extensive practice it becomes stimulus specific. A model is presented, which assumes that only at the initial stages of practice is the unused “neural pathway” inhibited each time the stimulus is an alternation.     

Training group therapists through the study of countertransferences

This article presents an experiential approach to supervision which evolved over a 15 year period. Through the use of the feelings induced in a group of colleagues, the countertransferential difficulties of the presenter can be ascertained. From there the dynamics of the group under discussion can be sorted out, and interventions can be developed. Various forms of countertrans-ferential reactions are described. Examples are offered to link practice with theory.Address delivered at the Boston Institute for Psychotherapies Conference on Supervision: Theory and Process on November 3, 1979.     

Figurai vs. configural effects in the filled duration illusion

Patterns varying in form goodness and size were presented for 15, 30, and 45 msec. The experiment included three independent groups of subjects. Half of the first group were presented size variations with good figures, while the other half were shown size variations with poor figures. Half of the second group were presented goodness variations with small figures, while the other half were shown goodness variations with large figures. A third group experienced variations in both goodness and size. The major findings were: (1) poor figures and large figures were judged “longer” than good or small figures when varied within a session; (2) this effect vanished when the different levels of size or goodness were presented to separate groups of subjects; (3) the magnitude of the difference in temporal estimation was the same for size and goodness when each was varied in isolation; (4) when size and form goodness were varied orthogonally in the same session, both dimensions produced reliable changes in temporal estimation. These data are discussed in light of current theoretical explanations of the filled duration illusion.     

The recovery of feelings in a folktale

The purpose of this essay is to explore the symptom of the denial of feelings and the subsequent recovery of feelings in relation to the task of uniting the human self. The spiritual, emotional, and physical implications of an exemplary narrative from the collection edited by Jacob and Wilhelm Grimm are discussed in relation to the telescoping of the emotion of fear, the sensation of shuddering, and the experience of anxiety about the integrity of the self. The reader is cautioned that the study of folktales enriches our telling of them and is itself justified by that telling.     

Integrality over different paradigms: Card sorting and two-stimulus matching

Orthogonal interference—indicating the cohesiveness between geometrical dimensions—was examined using two separate tasks: (1) card sorting and (2) two-stimulus matching requiring same/different responses. The card-sorting results of the present experiment were contrasted with the results of our previous research (1977, 1979) which used the two-stimulus matching task. Results were generally similar in that the orthogonal interference and, consequently, the degree of integrality/separability were the same for both tasks. Evidence was found for the emergence of a new nominal dimension. This and other results are only compatible with a weaker form of the global-to-local hypothesis of perceptual processing.     

A comparison of parent and teacher reports of selected adaptive behaviors of children

Assessment of children's adaptive behavior has been recommended for full multidimensional and nondiscriminatory evaluations. Additionally, previous research has reported discrepancies between teacher and parent reports on adaptive behavior. The purpose of this study was to compare mother and teacher reports on two scales from the Adaptive Behavior Inventory for Children of the System of Multicultural and Pluralistic Assessment (SOMPA). Black students from second through fourth grades (N = 24; 4 males and 4 females per grade) in an urban, parochial school were selected. The interviewers were two trained female graduate students (one white, one black). Each child's mother and teacher were interviewed in accordance with SOMPA assessment procedures. The results indicated that there was little agreement (.38 to .64) between mother and teacher reports. Additionally, mothers tended to provide higher ratings of adaptive behaviors than did teachers, irrespective of grade level. Implications of these findings for the assessment of children's adaptive behaviors are discussed.     

From the desk of the IFA president : International fluency association priorities: A poll of potential members

Potential members of the International Fluency Association (IFA) were polled regarding their fluency interests and perceived priorities for the organization during the year it was founded (in 1990). Results from 201 respondents indicated that a need for the IFA existed among researchers, clinicians, and representatives of self-help organizations for people who stutter. Improving the quality of treatment for those who stutter was considered the highest priority by all three groups. Researchers were of the opinion that the Journal of Fluency Disorders should be of higher quality than it had been in the past, and clinicians were most interested in reviews of new and relevant materials.
