Word-finding as a function of stimulus context: Children compared with aphasic adults

A study of object naming in 202 children, aged 5–11 years, demonstrated that varying the stimulus context affected the level of response accuracy. From age 6 to 10, completing a sentence with a noun (auditory) yielded the lowest error scores, naming objects upon hearing a definition (also auditory) produced most errors, while responding with names to pictured objects was of intermediate difficulty. This is the same order of object naming difficulty found in adult aphasic patients. Children older than 10 do not appear to be affected by stimulus context in their object naming. Results are discussed in terms of the relative syntactic difficulty of the two auditory conditions, the unexpected sex differences, and the “aphaseoid” naming errors of children.     

Predictors of turnover of female factory workers

This study examines predictors of turnover of female factory workers in a multivariate framework. Findings indicate that organizational, job, and personal characteristics are equally important in explaining turnover. Variables significantly related to turnover were tenure, cycle time, peer leadership, communication flow, training time, family income, and satisfaction with pay. The AID technique was demonstrated as a means of identifying interaction effects.     

Perspectives on Psychology and Law

The past decade saw an explosive growth in psychological research on law (particularly the judicial process) that continues unabated. This article presents an intellectual history of this research and a critical assessment of its contemporary developments. It begins by tracing four stages in the relations between psychology and law that serve to place present scholarship in perspective. Then follow two sections consisting of conceptual, methodological, and jurisprudential critiques of two topics, respectively, that traditionally have been and still remain at the center of research attention: the pretrial phase of the criminal process (eyewitness identifications) and the criminal trial itself (jury selection, jury decision making, and presentations of evidence and law to the jury). Finally, some themes are culled from past and present experience that capture the mood, difficulties, and prospects of applying psychology to the law. The purpose of this theoretical overview of the field is to suggest some insights into two recurrent questions: why has psychological research not had more of an impact on the judicial process, and what can be done about it?     

Saccade latency and warning signals: Effects of auditory and visual stimulus onset and offset

Previous studies have found that a nonspecific visual event occurring at the fovea 50–150 msec after the onset of a peripheral target delayed the initiation of the saccade to that target. The present studies replicated and extended this finding by studying the effects of both visual and auditory warning signals, by examining the effects of onset and offset warning on manual response latency, and by investigating the effects of presenting the warning events in the periphery of the visual field. The results indicated that the interfering effects occur with visual but not auditory stimuli, with saccades but not motor responses, and when the visual warning event occurs either foveally or in the subject’s periphery. Implications for the processes involved are discussed.     

Life structure decisions: Factors related to career-marriage priorities in college youth

The present research conceptualizes life structure, or the pattern of life, as the ordering of priorities among competing alternatives. Intentions to emphasize career, marriage, or both were investigated for college students. Variations in these intentions were seen as resulting from differences in two classes of variables: (a) the perceived consequences of emphasizing the alternative; and (b) perceived normative pressures. A subjective probability model of the relationship between beliefs and behavioral intentions was used as a framework for determining the importance of these factors. The considerations identified as most likely to have a direct impact on life structure dealt primarily with interpersonal relations, particularly marriage and family. In general, the data suggested that the subjective probability model may be useful for further understanding of life structure decisions.     

Reading deficits in learning disabled children

The purpose of this study was to determine whether LD children exhibited problems in the processes of attention, memory, or syntactical awareness when decoding written prose. Eighteen LD children and 18 normal controls were matched for initial word recognition skills. Subjects were then trained to read a list of individual words to criterion. Subsequently, they were tested on their ability to decode the same words in paragraph form, presented both immediately after training, and then again one week later. Half the children read paragraphs following standard English syntax, while the other half read a syntactically scrambled version of the same paragraph. The results indicated that a major contributing factor in the reading (decoding) difficulties demonstrated by the LD children derived from problems of acquisition and retrieval from long-term memory storage. The results were discussed in terms of their implications for the developmental lag theory of learning disabilities.     

An impulse-timing theory for reciprocal control of muscular activity in rapid, discrete movements

Much remains to be learned about how agonist and antagonist muscles are controlled during the production of rapid, voluntary movements. In an effort to summarize a wide body of existing knowledge and stimulate future research on this subject, an impulse-timing theory is presented which attempts to predict the activity of reciprocal muscles based on certain characteristics of a movement. The basic tenet of the theory is that variables of movement time, movement distance and inertial load have fairly predictable effects on the underlying muscular activity of the agonist and antagonist muscles during the production of rapid and discrete, voluntary movements. The theory is derived from the kinematic work of Schmidt, Zelaznik, Hawkins, Frank and Quinn (1979) and supporting evidence from studies which have used electromyographic (EMG) recordings of agonist and antagonist muscles during rapid movements. Issues related to synergistic muscle control, central and peripheral control of reciprocal muscle activity, muscle control, and neurological disorder and the relationship between impulse-timing and mass-spring control are discussed in the final section.     

Stress-management training: Evaluation of effects on school psychological services

School psychologists participated in a cognitive-behavioral stress-management training program. The data showed decreases in self-reported anxiety and increases in job satisfaction of school psychologists as a result of the training. In addition, teacher satisfaction with school psychological services increased after participation in teacher inservice workshops generated as a result of training the school psychologists.     

Human figure drawings of gender-problem children: A comparison to sibling,psychiatric, and normal controls

The Draw-a-Person test was used to evaluate a number of questions regarding children referred for potential problems in their gender-identity development (N = 36). Sibling (N = 31), psychiatric (N = 23), and normal (N = 30) children served as comparison groups. The major results included the following: (1) The gender-referred children were more likely to draw an opposite-sex person when requested to "draw a person" than were the other three groups; (2) the gender-referred children who drew an opposite-sex person were more likely to play with opposite-sex toys and dress-up apparel on a free-play task than were the gender-referred children who drew a same-sex person; (3) the gender-referred children drew taller opposite-sex persons than same-sex persons; (4) using Koppitz's (1968) criteria, the normal children had a smaller proportion of emotional disturbance indicators in their same-sex drawings than did the other three groups. These findings were discussed with regard to psychometric and interpretive issues in the assessment of children with atypical gender-role behavior.     

Written spelling deficit of Broca''s aphasics

The purpose of this study was to investigate the nature of the written spelling deficit manifested by Broca's aphasics. Four spelling tests were given to eight Broca's aphasic patients. Analysis of misspelling errors led the investigators to conclude that Broca's aphasics do not spell phonically, but rather adhere exclusively to a visual/orthographic strategy. Possible cognitive deficits underlying the spelling problem are identified. The written spelling deficit is related to other features of the syndrome of Broca's aphasia, and finally, speculations are offered concerning the neurological substrate of written spelling in Broca's aphasic patients.
