Within-modal and cross-modal reliabilities of two laterality tests

Sixteen right handers were given four tests of a dichotic listening recall task (concrete words) and a visual half-field recall task (letters). There was a significant right ear and right visual half-field superiority for the four test sessions, with improvement in recall scores over sessions. Pearson correlations for each ear on the four dichotic tests ranged from .74 to .90. Correlations on the visual half-field scores, however, were significant only after the first session. Analysis of stability in lateral preferences across modalities revealed stable and reliable performance, particularly in the last two testings, where 81.3% of the subjects had a right-sided asymmetry. Cross-modal correlations, however, were not significant. Implications regarding predictions of speech laterality are discussed in the light of these findings.     

Locus of selectivity in a visual memory task using a color value indicator

Selection of high vs low valued letters from a briefly presented visual array was investigated. An indicator specifying the value of letters occurred before or after the array. Selection could occur during input to memory or during output from memory in the before condition, but only at output in the after condition. Previous research using an alphabetic instruction, which required letter identification prior to selection, attributed selection to output. A color instruction in the -present experiment, not requiring letter identification, showed the locus of selection to be at input. Experiment 2 replicated these findings and used an interference technique to add further support. In addition, contrary to previous findings, these results indicated that the selection process caused no deficit in overall recall.     

Interview training with adolescents—A controlled group study incorporating generalization and social validation

Ten school-leavers were allocated either to an interview-training group (E) or a discussion control group (C) for three sessions. For E group a combination of modelling, coaching, roleplay, feedback and discussion was used to train both verbal and non-verbal interview skills. An attempt was made to programme generalization of treatment effect into training and subjective evaluations of interview skill were made by an experienced Personnel Officer to assess the social importance of the skills trained. After C group had completed three sessions to control for the non-specific effects of being in therapy, they received the same training as E group. Subjects were assessed using videotaped roleplayed interviews at the beginning and end of each training phase. After training E group showed significant improvements on both global and specific ratings of interview skill compared to C group; there was evidence of generalization and maintenance of treatment effect and the social importance of the skills trained was substantiated by the subjective evaluation data. C group then went on to replicate the changes in E group.     

The role of second formant transitions in the stop-semivowel distinction

An experiment was conducted which assessed the relative contributions of three acoustic cues to the distinction between stop consonant and semivowel in syllable initial position. Subjects identified three series of syllables which varied perceptually from [ba] to [wa]. The stimuli differed only in the extent, duration, and rate of the second formant transition. In each series, one of the variables remained constant while the other two changed. Obtained identification ratings were plotted as a function of each variable. The results indicated that second formant transition duration and extent contribute significantly to perception. Short second formant transition extents and durations signal stops, while long second formant transition extents and durations signal semivowels. It was found that second formant transition rate did not contribute significantly to this distinction. Any particular rate could signal either a stop or semivowel. These results are interpreted as arguing against models that incorporate transition rate as a cue to phonetic distinctions. In addition, these results are related to a previous selective adaptation experiment. It is shown that the “phonetic” interpretation of the obtained adaptation results was not justified.     

ACQUISITION OF SIGN LANGUAGE BY AUTISTIC CHILDREN. I: EXPRESSIVE LABELLING

There has been growing interest in teaching sign language to autistic children who have failed to develop speech. However, controlled experimentation in this area is nonexistent. In the present study, four nonverbal autistic children were taught expressive sign labels for common objects, using a training procedure that consisted of prompting, fading, and stimulus rotation. The efficacy of the procedure was demonstrated in a multiple-baseline design across objects. The results were reliable, replicable across children, and generalizable across therapists. A stimulus control analysis demonstrated that, for three of the children, correct signing was controlled solely by the visual cues associated with the presentation of a given object and was independent of the auditory cues related to the same object. These latter results are discussed with respect to the known perceptual and linguistic deficits of autistic children.     

“Using New Eyes”: Photography as a Spiritual Practice for Faith Formation and Worship

This article presents three cases of how Lutheran groups used photography as a spiritual practice in processes that led to group spiritual reflection for faith formation and worship: a photography club; a Photography as a Spiritual Practice mini‐course in a parish; and a six‐month parish project of communal art‐making of liturgical media art for one church's Easter Vigil readings.     

A panel study of married women's work patterns

In the attempt to overcome shortcomings of previous research on women's employment patterns, married women's employment behavior was examined successively over a five year period (1976–1981). Logistic regression and discriminant function analyses were performed on a sample of 366 wives in dual earner families from the Panel Study of Income Dynamics. Attitudes as well as work and family factors differentiated women who worked continuously full-time from women who worked either part-time or intermittently during the five year period. The findings are discussed in the context of social change and the impact of changing norms on married women's work patterns.An earlier version of this paper was presented at the Annual Meeting of the American Psychological Association, New York, NY, August 1987. Comments and suggestions of Barbara A. Gutek are greatly appreciated.     

Verbal Memory Abilities of Children With Brain Tumors

Several critical neuroanatomical structures and pathways for memory performance are located in the third ventricle region. This led us to predict that verbal memory abilities would be more impaired in children treated for third ventricle tumors compared to those treated for cerebellar tumors. Archival data was obtained from 24 pediatric patients with third ventricle region tumors and 18 pediatric patients with cerebellar tumors. Neuroradiological verifications of tumor involvement and hydrocephalus severity (i.e., Evans Index) on preoperative scans and MRIs proximal to the time of the neuropsychological evaluation were conducted. The potential confounds of hydrocephalus severity, seizure medication, age, radiation treatment, and chemotherapy were addressed. Verbal IQ was comparable between tumor groups and in the Average range. The third ventricle region group performed significantly worse on list learning and delayed list recall compared to the cerebellar group. Their mean performance was in the clinically impaired range on both trials. The third ventricle region tumor group performed better than the cerebellar tumor group on Digit Span, a basic repetition, attention span task. These findings support the hypothesis that pediatric patients with third ventricle region brain tumors are more likely to be impaired on verbal recall tasks compared to pediatric patients with cerebellar brain tumors. In contrast, patients who were treated for cerebellar tumors were more impaired on the basic repetition, attention span task compared to patients who were treated for third ventricle tumors. Future studies should examine the specific neuroanatomical structures and pathways that are damaged and may influence differential cognitive impairments in children.     

Neuropsychological and adaptive functioning in younger versus older children shunted for early hydrocephalus

Previous research on children with hydrocephalus has not carefully examined age-related changes in neuropsychological and behavioral status. We present data on 28 children with early hydrocephalus and spina bifida who were studied in two age groups: 5 - 7.5 and 9 - 12.5 years. Age-related differences in language, memory, visuomotor skills, and adaptive behaviors were examined. Consistent with other studies, the total sample showed impaired motor, performance, verbal, communication, and learning skills. Comparisons between older and younger children showed: (1) except for memory, neuropsychological patterns of functioning were generally comparable across the age groups, and (2) older children demonstrated more difficulty on specific adaptive functions (socialization, learning, conduct). Shunted hydrocephalic children may be conceptualized as exhibiting the syndrome of nonverbal learning disabilities. Clinical implications are discussed.
