Cerebral hemispheric mechanisms in the retrieval of ambiguous word meanings

Targets related to ambiguous primes were projected to the left and right visual fields in a lexical priming experiment with stimulus onset asynchronies (SOA) of 35 and 750 msec. Right visual field results were similar to our earlier results with central projection (G. B. Simpson & C. Burgess, 1985, Journal of Experimental Psychology: Human Perception and Performance, 11, 28-39). Facilitation was found for the more frequent meaning at both SOAs and a decrease in facilitation for the less frequent meaning at the longer SOA. In contrast, left visual field results indicated a decay of facilitation for the more frequent meaning at the longer SOA, while activation for the subordinate meaning increased. Results suggest that, while automatic processing occurs in both hemispheres, only the left hemisphere engages in controlled processing of ambiguous word meanings. In addition, the present results support the idea that the right hemisphere has a special role in ambiguity resolution and that the right hemisphere lexicon possesses a richer endowment than earlier thought.     

Nonverbal communication as a compensative strategy for severely nonfluent aphasics? A quantitative approach

Seven severely nonfluent aphasics and one relative or close friend were investigated in an interview situation. The conversation was videotaped and analyzed for the use of nonverbal communication between aphasic and partner. The results indicate that the group of aphasics used significantly more frequently and for a significantly longer period of time nonverbal channels of communication than their healthy partners. The aphasic patients also used significantly fewer speech-focused movements and significantly more codified gestures. Nonverbal elements were more frequently used as speech substitutes by the group of aphasics.     

S-R compatibility between response position and destination of apparent motion: evidence of the detection of affordances

In choice reaction time, stimuli and responses in some combinations (e.g., based on spatial arrangement) are faster than in other combinations. To test whether motion toward a position yields faster responses at that position, a computer-generated square in front of one hand appeared to move either toward that hand or toward the other hand. Compatible responses (e.g., motion toward left hand/left response) were faster than incompatible responses, even when that opposed traditional positional compatibility. In Experiment 2, subjects responded to the same stimuli but with both hands left, right, or on the body midline. Medial responses were the fastest, showing that destination, rather than mere relative position, was a critical variable. It was suggested that spatial compatibility effects are not unique to position but apply to a variety of task situations, describable by J.J. Gibson's theory of affordances, in which he claims that one perceives the actions (e.g., catching) permitted in a situation.     

Understanding the central processing limit in consistent-mapping visual search tasks

Effects of load (i.e., the number of stimuli in the display) have been observed in multiple-frame studies using a consistent mapping of stimuli to responses (e.g., Fisher, 1982, 1984). In a series of four experiments, it is shown that these effects are not the consequence of differences across the high- and low-load conditions in either decision noise or peripheral masking. Additionally, it is shown that of two modes of limited capacity (a limited-channel and divided-capacity model) considered as possible explanations of load effects in tasks where subjects are required to locate a target, only one--the limited-channel model--is consistent with the results from all three location tasks. Finally, it is argued that the limited-channel model predicts not only the behavior observed in the four consistent-mapping experiments reported in this article but also the behavior observed in several related consistent-mapping tasks (Kleiss & Lane, 1986; Shiffrin & Gardner, 1972).

Work involvement among college-educated women: A methodological extension

This paper has two objectives: (1) to develop a more complex measure of work involvement than that typically used, and (2) to correlate this measure with selected lifestyle/family and work variables. The data were drawn primarily from a 1981 survey of 110 female graduates of a large Midwestern university who completed their undergraduate degrees in 1967. Respondents were categorized as high, moderate, or low on a work involvement index based on four variables: work continuity, work status, current or most recent occupation, and educational achievement. Findings in the area of lifestyle/family suggest that high work-involved women are more likely to be single and to marry later when they do marry, less likely to have children, and less likely to perceive conflicts between marriage/relationships and/or children and a career. Findings in the area of work suggest that high work-involved women are significantly more likely to work in male-dominated occupations and to earn salaries of $20,000 or more. High work-involved women are also significantly more likely to be supervisors, to report that most of the people in their work group or branch are below them in rank/position, to be working with all or predominantly men, to have men above them in rank, and to have experienced sex discrimination on the job. In the area of job satisfaction, the differences by work involvement are not as pronounced. High work-involved women are significantly more likely to be employed and not job hunting — one measure of job satisfaction. However, they are no more or less likely than moderate or low work-involved women to perceive their job as a compromise with what they expected or to report overall job satisfaction. Some directions for future research are discussed.Environmental Strategies, Inc.Preparation of this report was supported, in part, by the Providence College Fund to Aid Faculty Research.

Coping with victimization: The impact of rape on female survivors,male significant others,and parents

This paper reports on an unusual study of survivors of rape and the effects on the victim, her significant male other person, and her parents. All survivors were victims of the same rapist and were interviewed from 21 months to ten years after the event. The study indicates that the long-term effects of rape may be more significant than previous researchers and practitioners thought was the case. Recommendations are given for more effective help for survivors and those close to them.This study was funded by the Ohio Department of Mental Health, Office of Program Evaluation and Research, Columbus, Ohio, 1985.     

Learning from lectures: The effect of varying the detail in lecture handouts on note-taking and recall

Previous research on the effect of lecture handouts on student learning indicates that students who are given skeletal handouts usually perform better in course examinations than students who take all their own notes. The present study investigates whether the amount of detail in the handout is a critical factor in this. A randomized groups experiment was conducted in the context of a course on dental surgery. Four lecture handout conditions (headings and full text; headings and key points; headings only; no supplementary materials) were compared on tests 2 days and 2 weeks after the lecture. The significant differences between conditions were: ‘headings only’ better than ‘headings and key points’ on the first test; ‘headings only’ better than ‘no supplementary materials’ on the second test; and ‘headings and full text’ better than ‘no supplementary materials’ on the second test. These results indicate that the amount of detail is a critical factor in handout effectiveness.
