Compensation for Jaw Fixation by Aphasic Patients

The ability to compensate for fixation of the jaw by a bite block was investigated in 6 nonfluent aphasics, 6 fluent aphasics, and 10 normal control subjects. Acoustic analyses of the vowels [i u a æ] and fricatives [s s] revealed substantial but incomplete compensation for the perturbation in all three subject groups. Perceptual identification scores and quality ratings by naive and phonetically trained listeners indicated poorer identification of the high vowels [i u] under compensatory conditions relative to normal production. Of particular interest was the fact that all three groups of subjects exhibited similar patterns of results. The findings suggest that any deficit in speech motor programming demonstrated by the nonfluent aphasic patients did not affect compensatory abilities. Results are discussed with respect to normal speech adaptation skills and the nature of articulatory breakdown in nonfluent aphasia.     

Internal Objects - A Theoretical Analysis of Jungian and Kleinian Models

In this paper I discuss the ways in which experimental and objective research from cognitive science and developmental psychology can help analysts evaluate the theoretical models of mental objects which we use; I indicate the ways in which such evidence tends to support models of internal objects as mental representations or developmental capacities rather than as wish-fulfilling expressions of instinctual drives. This land of empirical evidence is not just of academic interest but also has direct clinical relevance, particularly with borderline patients; such patients' sense of identity is totally dependent on the analyst's understanding of their internal world and for this to be misunderstood by the analyst can be catastrophic. An accurate theoretical model of mental objects can therefore help analysts to contain their patients more effectively.     

Assessment of Supervisee Developmental Level and Supervision Environment Across Supervisor Experience

Supervisors representing different levels of experience viewed videotape vignettes of counselors demonstrating the first three developmental levels of Stoltenberg's (1981) Counselor Complexity Model. Supervisors assessed each counselor on his or her developmental level and on the supervision environment he or she would provide for the trainee. Results indicated that supervisor experience did not influence the assessment of developmental level or the ability to make accurate environmental matches. Nevertheless, supervisors had the most difficulty accurately assessing counselors representing Level 2 in Stoltenberg's model and tended to make relative judgments about counselor developmental level. Implications for training and further research are discussed.     

Distortions and fluctuations in topographic memory

Two experiments dealing with, the learning of a space by map or by navigation approached the questions of equivalency of the cognitive processes involved in spatial information and of response fluctuation. In the first experiment, 11 subjects were asked to situate, six times, 18 lo-cations on a blank map. In the second experiment, the subjects were first given 3 min to learn a map with 12 locations marked, and then asked to reproduce it. The task was repeated six times, using three different maps. This gave us several trials per subject, so that distortion could be distinguished from response fluctuation. In Experiment 1, the range of values was the same for response inaccuracy and response, fluctuation; in Experiment 2, the range was greater for response inaccuracy than for response fluctuation. The results showed that space learning by navigation and space learning by map involve different cognitive processes.     

Computing Cohen’s kappa coefficients using SPSS MATRIX

This short paper proposes a general computing strategy to compute Kappa coefficients using the SPSS MATRIX routine. The method is based on the following rationale. If the contingency table is considered as a square matrix, then the observed proportions of agreement lie in the main diagonal’s cells, and their sum equals the trace of the matrix, whereas the proportions of agreement expected by chance are the joint product of marginals. The generalization to weighted kappa, which requires an additional square matrix of disagreement weights, both matrices having the same order, becomes possible by the use of the Hadamard product-that is, the elementwise direct product of two matrices.     

Resetting the pitch-analysis system: 1. Effects of rise times of tones in noise backgrounds or of harmonics in a complex tone

The question of whether sudden increases in the amplitude of pure-tone components would perceptually isolate them from a more complex spectrum was investigated in two experiments. In Experiment 1, a 3.5-sec noise was played as a masker. During the noise, two pure-tone components of different frequencies appeared in succession. Subjects were asked to judge whether the pitch sequence went up or down. The rise time of these components had only a small and inconsistent effect on discrimination. In Experiment 2, the 3.5-sec background signal was a complex tone. The amplitudes of two of its components were incremented in succession. Again, subjects judged whether the pitch pattern went up or down. This time there was a sizable, monotonic effect of the rise time of the increments, with more rapid increments leading to better discrimination. The difference between the two results is interpreted in terms of the auditory system’s response to changing and unchanging signals and the role of its “sudden-change” responses in attracting perceptual processing to certain spectral regions.     

Forms of Authority and the Real Ad Verecundiam

This paper provides a typology of appeals to authority, identifying three distinct types: that which is based on a command; that which is based on expertise; and that which is based on dignity. Each type is distinguished with respect to the reaction that a failure to follow it ordinarily evokes. The rhetorical roots of Locke's ad verecundiam are traced to the rhetorical practices of ancient Rome.     

Gifted Achievers and Underachievers: A Comparison of Patterns Found in School Files

Underachievement in gifted students has perplexed educators and parents for decades. Researchers are continually looking for information about the nature and patterns of gifted underachievers that will enlighten those concerned. Counselors are particularly involved, because they often are asked to provide illumination and interventions. This study demonstrates how information in the cumulative school file, accessible to the school counselor, is a rich resource for understanding the patterns of achievement and underachievement among students identified as gifted and for use in planning interventions for students at risk for underachievement. Participants were gifted students (N = 153) who were determined to be either achievers or under-achievers, based on their grade point average at graduation. High and moderate achievers and moderate and extreme underachievers were compared on information found in the school file, such as attendance, tardiness, course selection, and onset and duration of underachievement. Results indicate that there are differences between achievers and underachievers on a number of variables found in the school files. Profiles of these groups are presented with suggestions for actions by counselors.     

Comparison of simultaneous prompting with and without error correction in teaching science vocabulary words to high school students with mild disabilities

This study compared the effectiveness and efficiency of simultaneous prompting with and without error correction during daily probe sessions in teaching science vocabulary words. The teacher presented the vocabulary word definitions as instructive feedback during training sessions. Five 16–17 year old students with disabilities participated in an adapted alternating treatments design that evaluated the simultaneous prompting strategy, error correction and instructive feedback. Instruction occurred in a group format using choral responding. The results indicate that (a) all students learned to read the vocabulary words, (b) simultaneous prompting with error correction was slightly more efficient for three of the five subjects in learning the targeted words, and four of the five students made fewer errors in this condition, (c) all students preferred simultaneous prompting with error correction over simultaneous prompting without error correction, (d) words mastered in both conditions generalized equally, (e) there were minimal differences between the two conditions in the collected maintenance data, and (e) students experienced only minimal improvement in their ability to define vocabulary words (instructive feedback). Discussion focuses on issues for further research and implications for instructional practice with simultaneous prompting, error correction and instructive feedback.
