Specific word transfer as a measure of processing in the word-superiority paradigm

Explanations of context effects in the Reicher-Wheeler task and the letter-identification task appeal to word-based processing, yet these tasks provide no explicit measure of word processing. An experiment is reported which was designed to investigate the use of transfer in the word-identification task as a measure of word-based processing in letter-identification tasks. It was found that encoding manipulations that determined whether a word-superiority effect was or was not found in a letter-identification task (e.g., Thompson & Massaro, 1973) also determined whether transfer was or was not found in a subsequent word-identification task. The results of the experiment are discussed in terms of the utility of using transfer experiments as converging evidence about the presence and/or absence of processes that cannot be directly measured in other experimental paradigms.     

Contextual influences in aphasia: effects of predictive versus nonpredictive narratives

The influence of prior linguistic predictive and nonpredictive context on the comprehension of reversible passive sentences was investigated in 16 adults with aphasia. Eight subjects were classified as fluent and 8 as nonfluent. Subjects were presented with the sentences in isolation and preceded by nonpredictive and predictive contextual paragraphs. The overall results indicated that the subjects benefited significantly from the prior contextual narratives regardless of whether the paragraphs were predictive or nonpredictive. There were no significant differences between the two subject groups. The significant facilitation generated by the nonpredictive context suggests that redundancy of information may play a role in comprehension.     

Parts of visual objects: an experimental test of the minima rule

Three experiments were conducted to test Hoffman and Richards's (1984) hypothesis that, for purposes of visual recognition, the human visual system divides three-dimensional shapes into parts at negative minima of curvature. In the first two experiments, subjects observed a simulated object (surface of revolution) rotating about a vertical axis, followed by a display of four alternative parts. They were asked to select a part that was from the object. Two of the four parts were divided at negative minima of curvature and two at positive maxima. When both a minima part and a maxima part from the object were presented on each trial (experiment 1), most of the correct responses were minima parts (101 versus 55). When only one part from the object--either a minima part or a maxima part--was shown on each trial (experiment 2), accuracy on trials with correct minima parts and correct maxima parts did not differ significantly. However, some subjects indicated that they reversed figure and ground, thereby changing maxima parts into minima parts. In experiment 3, subjects marked apparent part boundaries. 81% of these marks indicated minima parts, 10% of the marks indicated maxima parts, and 9% of the marks were at other positions. These results provide converging evidence, from two different methods, which supports Hoffman and Richard's minima rule.     

Lesbian Partner Abuse: Implications for Therapists

Silence surrounds the issue of lesbian battering. Lesbian victims of partner abuse are even less likely than are their heterosexual counterparts to seek help in shelters or from counselors because of the overlay of homophobia that exists both in the battered women's movement and among mental health professionals. In addition, many lesbian and many lesbian-supportive therapists hold an idealized and unrealistic picture of the nature of lesbian relationships, leading them to deny the existence of buttering among lesbian couples. The nature, severity, and prevalence of abuse in lesbian relationships is addressed; current counseling and treatment models dealing with battering relationships are analyzed; and a counselor advocacy model for working with lesbian partner abuse, drawing from the experience of activists in the battered women's movement and our clinical experience, is suggested.     

Age differences in memory performance and memory ratings as measured in a sample survey

Age differences in memory performance were studied in a probability sample of a cross-section of 1,491 adults living in the Detroit metropolitan area, with an oversample of those age 60 and older. Both a recall and a recognition measure were adapted to the survey context by querying respondents about the nature of the questions asked in an immediately preceding interview. Subjective memory assessment was also measured, using global memory ratings performed by the respondent, his or her spouse, and the interviewer. A clear, age-related decline in memory performance was found in this population sample. Subjective memory assessment also declined across age groups, but the relation was weaker. On the basis of multiple regression analyses of the recognition measure and the respondent's self-rated memory, which were judged to have the best measurement qualities, a substantial part of these age differences can be accounted for by differences in sociodemographic composition between age groups, by cognitive functioning and physical health.     

Mental health expert witnesses: Of science and crystal balls

This article reviews the history of and basis for mental health testimony. It surveys the roles of such experts in the legal system and the concomitant problems with current approaches. Finally, it suggests specific reforms that may improve the use of mental health experts in legal proceedings.     

The written summary in group psychotherapy revisited

This paper addresses the use of the weekly written summary with patients in group psychotherapy. In an effort to stimulate group process and effect cotherapist communication, the authors instituted this group recording in an ongoing psychodynamically oriented mixed adult group. While the utilization of this device did, in fact, stimulate the group process and became an important part of the group's life, the therapists additionally saw significant effects upon their working alliance. These included increased focused dialogue upon group dynamics, more purposeful planning for group interventions, and heightened awareness of the significance of interventions in the group.Ms. Bosman-Clark is formerly Clinical Instructor, Department of Psychiatry, Baylor College of Medicine.     

The impact of drug screening on selection decisions

This paper discusses the use of drug screening for employee selection decisions. Common methods of drug screening are described, and a recent study of drug screening accuracy is summarized. It is argued that drug screening is subject to the same standards as are other selection procedures, and that human resource professionals must assume responsibility for understanding the potential problems associated with drug screening. Issues relevant to determining the benefits of drug screening are discussed, and an illustration of the impact of drug screening on decision accuracy is presented. It is suggested that, in many instances, the value of drug screening in the selection process may be low enough to warrant serious concern. Implications for human resource research and practice are noted.An earlier version of this paper was presented at the 95th Annual Convention of the American Psychological Association in New York; August 31, 1987. The authors would like to thank Michael Bramel for his assistance in locating and summarizing some of the medical literature cited, and two anonymous reviewers for their helpful comments.
