Category-Based and Feature-Based Cognitive Processes: The Role of Unfavorable Information1

Recent research on selection decisions suggests that favorable features (e.g., attractive physical features or positively-evaluated personality traits) can enhance ratings of applicant suitability, but little research has examined the impact of unfavorable features. Theories of person perception distinguish between two information processing strategies: category-based and feature-based. We predicted that unfavorable features would influence selection decisions only when raters used feature-based processing strategies. Results suggest that applicant features' prototypicality and favorability can compensate for one another, with applicants' negative features resulting in a disadvantage only when the applicant is perceived as nonprototypical.     

The responsibilities of counsellor supervisors: A qualitative study

A study was carried out to investigate whether supervisors of counsellors considered themselves to be clinically responsible for the work of their supervisees, what responsibilities they considered themselves to have for the counsellors' work, and how they managed their responsibilities. The purpose of the study was to enhance the counselling profession's understanding of the responsibility of supervisors and of the supervisory relationship. The study was confined to supervisors working in private practice. Ten experts in the field of counselling and supervision were interviewed, using a semi-structured questionnaire. The interviews were analysed using the 'constant comparative method'. They revealed that the participants would not use the term 'clinical responsibility' to describe their responsibilities. There were mixed views about the nature of the responsibility of the supervisor when supervising counsellors practising independently. The participants indicated a preference to supervise only the most experienced counsellors, with whose practice they were already familiar and in whose work they already had considerable confidence. None of the supervisors interviewed considered themselves to be legally responsible for the counsellors' work. All the participants were aware that the risks associated with counselling in private practice could be considerable and had an acute sense of responsibility for the content of the work. Reluctance to take action against supervisees who were in breach of the code of ethics was expressed. There was scepticism about the requirement for them to have supervision for their supervisory work. Implications for the practice of counselling supervision and for the profession are discussed.     

Peer assessments of performance and ability: An exploratory meta-analysis of statistical artifacts and contextual moderators

The validity of peer assessments as an additional source of information in personnel decision-making was assessed via Hunter and Schmidt's (1989) meta-analytic approach. Fifty-six correlations on peer assessments of ability and performance were located. After correcting for sampling error and imperfect reliability, the mean correlation was estimated to be .69, with a 95% confidence interval of .46 to .92. Also, contextual factors hypothesized to affect observed validities were evaluated. Although much potentially important information is not reported in available studies, the data suggested that use of peer assessment data, time of acquaintance, and type of criterion affect observed validity. Implications for future research are discussed.     

Cognitive effects of mild head injury in children and adolescents

A comprehensive review of recent neuropsychological studies of mild head injury (MHI) involving children and adolescents is presented. The seminal work of Rutter and his colleagues is reviewed. An alternative conceptualization of MHI as proposed by various researchers is elaborated and further research investigating the cognitive sequelae of MHI is reviewed. MHI is discussed within the context of development and information processing models. Finally, the sequelae of MHI are reviewed with respect to academic functioning. Methodological problems inherent in studies of MHI are identified and discussed. The studies reviewed here support the conclusion that both the cognitive and emotional consequences of MHI should receive serious evaluation.     

Fears about Seeking Therapeutic Help: The Effect of Sex of Subject, Sex of Professional, and Title of Professional

96 subjects were asked to imagine that they had gone to their GP for help with an emotional problem. The subjects were further asked to imagine that the GP had referred them to either a male or female counsellor, clinical psychologist or psychiatrist. Whilst in role, subjects were asked to rate their concern about 15 possible fears of therapy, and to indicate their preference for a male or female therapist. There was little support for the hypothesis that female subjects would have lower fear ratings than male subjects. Equivocal support was found for the hypothesis that there would be an overall preference for female therapists. Results partially supported the hypothesis that fear ratings would be highest with respect to psychiatrists; the interaction of the sex of subject and the title of professional variables indicated that this was particularly so when the psychiatrist was female. The implications for counselling are briefly discussed, with regard to preparing clients for therapy.     

The NASA/LRC computerized test system

A new testing package, including apparatus and tasks, is described for the study of behavior of a variety of species in a variety of experiments. The package is described with respect to the kinds of comparative psychological investigations for which it is well suited. The preliminary data generated within this new testing paradigm demonstrate that the NASA/LRC Computerized Test System provides a flexible yet powerful environment for the investigation of behavioral and psychological processes.     

The effect of duration of exposure on systematic desensitization and extinction.

An important variable which has only recently received attention (Proctor, 1968; Watts, 1971) is the influence of intra-item exposure time to aversive stimuli on systematic desensitization. Long single exposure to hierarchy items was more effective in reducing avoidance behavior than short exposure (Ross and Proctor, 1973). It is possible, therefore, for duration of exposure to be a confounding variable in previous desensitization research.In studies where exposure only conditions were ineffective (Davison, 1968; Lomont and Edwards, 1967), the visualization time was less than 15 sec. Successful utilization of extinction-like procedures employed longer exposure times (Vodde and Gilner, 1971 for 20–30 sec; Crowder and Thornton, 1970 for 30 sec; Sue, 1972 for 20 sec; Nawas, Welsch and Fishman, 1970 for 60 sec: Wolpin and Raines, 1966 for up to 10 min).Intra-item exposure time may also account for the discrepant findings on the influence of cognitive variables on the efficacy of systematic desensitization. In the studies where expectations or therapeutic instructions were important (Leitenberg et al., 1969; Valins and Ray, 1967), subjects were exposed to aversive stimuli for 10–15 sec. Where positive expectations were unimportant, the exposure time was longer (McGlynn and Mapp, 1970 for 20–30 sec; McGlynn, Gaynor and Puhr, 1972 for 20–30 sec; McGlynn, Reynolds and Linder, 1971 for 20–40 sec; Lomont and Brock, 1971 for 60 sec). Therapeutic expectations, relaxation, and other variables may assume importance during periods of short exposure.So far, there has been no adequate investigation of intra-item exposure time on both extinction and desensitization. The procedures employed by Watts (1971) and Proctor (1968) do not allow such a comparison to be made. The purpose of the present study is to examine the influence of short (5 sec) and lengthy (30 sec) exposure to aversive stimuli on extinction and desensitization conditions.In line with the results of Davison (1968) and Lomont and Edwards (1967), it was predicted that exposure of short duration would be less effective than exposure of longer duration under the extinction condition (Vodde and Gilner, 1971 ; Crowder and Thronton, 1970; Nawas et al., 1970; Wolpin and Raines, 1966). No specific predictions were made on the desensitization groups. There were four experimental groups: (1) two exposure only groups (visualization for either 5 sec or 30 sec), and (2) two systematic desensitization groups (visualization for 5 sec or 30 sec). A no-treatment control group was also employed.     

What makes a good counsellor? An analysis of ways in which counsellor trainers construe good and bad counselling trainees

As part of an investigation into criteria used by counsellor trainers to distinguish between good and bad students of counselling, experienced counsellor trainers were asked to complete a repertory grid. Each trainer was asked to list five good counsellor trainees and five not so good or bad counselling trainees they had worked with, as elements for the grid. Repertory grid forms were provided by the researcher with spaces for ten constructs which were elicited from the trainers in the standard triadic manner. For each elicited construct subjects were asked to rate each trainee on a five point scale. Twenty-seven correctly completed grids were collected. The 262 constructs elicited were conflated into 22 semantically similar categories by the researcher and independent raters. The data was subjected to statistical analysis using the Statistical Package for the Social Services (SPSS). Overall the constructs that were most frequently used in describing trainees were open-closed, personable/aloof, secure-insecure, professionally skilled-unskilled. The mean differences for scores of good and bad trainees for each of the 22 conflated constructs were calculated. The greatest mean difference related to professional competence. The 22 conflated constructs were subsumed into three categories, and the mean of the difference between ratings for good and bad trainees within each category was calculated. Counselling related competence showed the greatest mean difference. Implications for counselling course curricula and the selection and assessment of counsellor trainees are discussed.
