A multitrait-multimethod analysis of the preschool behavior questionnaire

The Preschool Behavior Questionnaire is a teacher rating instrument yielding a total score reflecting overall level of adjustment and three subscale scores labeled Hostile/Aggressive, Anxious/Fearful, and Hyperactive/Distractible. This study assessed the convergent and discriminant validity of this teacher rating measure against two alternative measures within a multitrait-multimethod analysis. The results supported the construct validity of the Hostile/Aggressive and Anxious/Fearful scores as well as the overall score. There was, however, no support for the validity of the Hyperactive/Distractible score.This research was supported, in part, by a grant from the Pickering Foundation. The authors would like to thank Maria Bhaneja for her help in the collection and coding of data. Thanks are also extended to the teachers and children who participated in the study.     

Language development after unilateral brain injury.

This longitudinal study describes the growth of syntactic abilities and vocabulary size in nine children with unilateral antepartum or perinatal brain injury. Five children with left hemisphere damage (LHD) and four with right hemisphere damage (RHD), ages 15 to 48 months, were evaluated on three or more occasions. Language samples generated from parent-child interaction were transcribed, coded, and analyzed using the Child Language Data Exchange System. Individual growth trajectories were constructed by graphing three dependent variables--MLU, scores on the Index of Productive Syntax (IPSYN), and number of different words--as a function of the child's age. One subject remained in a prelinguistic stage throughout the study. Simple linear functions best described the growth of MLU, IPSYN scores, and vocabulary in the other eight children. The slopes of the individual growth trajectories, the graphic representations of rates of progress, were comparable in the eight children. Seven children showed developmental delays in initial word use and five in the onset of multiword utterances. However, by age 24 months, four children with LHD and two children with RHD had syntactic capabilities comparable to those of children without brain injuries. The developmental patterns suggested that both cerebral hemispheres may play critical roles in the very earliest stages of language acquisition. Some unilateral lesions caused little discernible effect on language outcome in the toddler-preschool years after the initial developmental delays.     

Developmental Career Assessment and Counseling: The C-DAC Model

The C-DAC model seeks to implement current development theory and to use innovative assessment measures together with improved counseling methods to improve vocational and life career counseling. At this stage, the project pays more attention to assessment, partly because if one is to counsel with career maturity in mind, one must understand the developmental status of the counselee. In career counseling, facts as well as feelings are important. Therefore, in this article the authors deal with the assessment of career development in detail, treating interests (measured by the Strong) and expressed preferences as basic status data to be viewed in the light of career maturity, the salience of life roles, and the values sought in life as moderator variables. The instruments are described and their use shown in a sample profile for assessment and checking by the reader in another readily available published source.     

Improving instruction for adults with developmental disabilities: Evaluation of a staff training package

Improvements in adaptive behavior among adults with developmental disabilities often depends on the quality of instruction delivered by direct-care staff. The present study evaluated the effectiveness of a multifaceted package for improving the quality of instructional interactions among three staff/adult dyads. Instructional interactions were first analyzed to identify areas for improvement. A multifaceted intervention package consisting of inservice training, participative management, and on-going feedback was then implemented in a multiple-baseline design across dyads. The package trained staff to increase their use of time delay and reinforcement strategies and these changes were associated with greater independence in a sandwich making task among two of the three participating adults. The results suggest direct observation of existing instructional interactions may provide valuable information when training staff to implement effective habilitative programs for adults with developmental disabilities.     

The role of attention and study time in explicit and implicit memory for unfamiliar visual stimuli

The effects of limited attentional resources and study time on explicit and implicit memory were studied using Schacter and Cooper’s possible and impossible objects in their recognition and object decision paradigm. In one experiment, when attention at study was limited by a flanking digits procedure, object recognition was diminished but object decision priming for possible objects was unaffected; in another experiment, limiting attention plus reducing stimulus study time impaired object recognition and eliminated object priming. Recognition memory and perceptual priming for previously unfamiliar visual stimuli were both influenced by attention, although to different degrees. The intervening variable of study time determined the degree to which priming was affected by attentional resources. These results support a limited capacity attentional model for both recognition and perceptual priming of unfamiliar visual stimuli, and they highlight the need for assessing the interaction of attentional resources and study time in explicit and implicit memory tasks.     

AUDITORY PITCH AS A PERCEPTUAL ANALOGUE TO ODOR QUALITY

Abstract— Experiments in cross-modal matching suggest that smells can be arranged by odor qualify along the color dimensions of hue and lightness. Here we report that subjects readily adjust the loudness-equalized pitch of on auditory tone to match a stimulus odor. The results allow odors to be arranged in sequence by their pitch-equivalents. The tone matches appear to be based on perceptual feature of olfaction other than stimulus intensity or pleasantness. The results suggest that features of odor quality may be more accessible and structured than previously acknowledged.     

Recency judgments as a function of word frequency: A framing effect and frequency misattributions

The effects of word frequency on judgments of recency of item presentation were examined in two experiments. Subjects in Experiment 1 were presented two mixed lists of high- and low-frequency words followed by a list assignment task for recognized items. It was found that subjects were biased toward assigning low-frequency words to the more recently presented list. Subjects in Experiment 2 were presented a single mixed list of high- and low-frequency words followed by either a relative recency of presentation judgment task or a relative primacy of presentation judgment task. Each word pair on the tests contained one high-frequency word and one low-frequency word. It was found that, for the recency judgment task, subjects were biased to select the low-frequency item as having been presented more recently. However, on the parallel primacy judgment task, there were no effects of word frequency; moreover, overall accuracy levels were higher with primacy than with recency instructions. We interpret the effects of word frequency on recency judgments in Experiments 1 and 2 in terms of a misattribution of frequency-related differences in recollection-based recognition. The finding that recency and primacy instructions produced different patterns of results provides further evidence (Flexser & Bower, 1974) for an effect on performance of the way in which the temporal judgment task was framed.     

ALCOHOL AND DATING RISK FACTORS FOR SEXUAL ASSAULT AMONG COLLEGE WOMEN

American societal norms frequently link alcohol, dating, and sexuality. This cross-sectional study examined the role of alcohol and dating risk factors for sexual assault among a representative sample of female students at a large urban university. Over half of the 1,160 women had experienced some form of sexual assault. Ninety-five percent of these assaults were committed by someone the woman knew and almost half of these assaults involved alcohol consumption by either the man, the woman, or both. Discriminant function analyses indicated that dating, sexual, and misperception experiences and alcohol consumption during these experiences predicted assault group status. Furthermore, alcohol consumption during consensual sex and sexual misperceptions were positively related to alcohol consumption during the sexual assault. The predictors of assault group status were similar for African American and Caucasian women. Theoretical implications are discussed and suggestions are made for combining alcohol and sexual assault prevention programming.
