Motion coherence and conjunction search: implications for guided search theory.

Feature integration theory has recently been revised with two proposals that visual conjunction search can be parallel under some circumstances--either because items with nontarget features are inhibited, or because items with target features are excited. We examined whether excitatory or inhibitory guidance controlled conjunction search for an X oscillating in one direction among Os oscillating in that direction and Xs oscillating in another. Search was affected by whether items oscillated in phase with each other, and it was exceptionally difficult when items with target motion moved out of phase with each other and items with nontarget motion moved out of phase. The results suggest that conjunction search can be guided both by excitation of target features and by inhibition of nontarget features.     

Representing narrative process in therapy: Qualitative analysis of a single case

In recent years, there has been increasing interest in an approach which views counselling and psychotherapy as being concerned with giving clients opportunities to articulate, examine and re-author aspects of their life-stories. However, most of the literature associated with this approach has been based on observations of clinical practice, and there is a need to develop more systematic research in this area. The present study uses qualitative methods to identify and categorize different types of narrative events occurring in therapy discourse. A representation is offered of the process by which experience is narrativized during therapy. The data for this analysis is drawn from an intensive study of one session of person-centred counselling. The issues involved in applying this method of qualitative analysis are discussed, and the implications of these findings for research and practice are outlined.     

Counsellor and client perceptions of the effectiveness of time-limited counselling in an occupational counselling scheme

Counsellors providing brief counselling (6 sessions) in a British Social Services Department completed post intervention questionnaires for 429 clients. These provided information on several measures about the degree to which they felt that their clients had benefitted from the counselling, how far they felt that the number of sessions was adequate, and the nature of the clients' problems. Two hundred and twenty-three of the clients also completed post-intervention questionnaires indicating their degree of satisfaction on a number of measures. There was fair agreement between counsellors and clients that outcomes were satisfactory, and that the number of sessions was adequate, although clients were more satisfied than counsellors. Counsellors identified a range of personal and occupational presenting problems, and around two thirds of problems belonged in the personal domain. Long-tern personal problems received lower satisfaction ratings and were more frequently referred on to other agencies.     

An analysis of rats' drinking-tube contacts under tandem and fixed-interval schedules of food presentation

Rats' lever presses and drinking-tube contacts were studied under fixed-interval schedules of food presentation and under a tandem schedule composed of three fixed intervals. One group of rats was exposed first to the tandem schedule, next to fixed-interval schedules of comparable interpellet intervals, and once again to the tandem schedule; a second group of rats was exposed first to a fixed-interval and then to the tandem schedule. Under the tandem schedule, lever presses occurred at a higher rate and were more uniformly distributed in time than under the fixed-interval schedule. Tube contacts emitted by rats exposed first to a fixed-interval schedule consisted mostly of tongue contacts, which occurred at a high rate shortly after food; tube contacts emitted by rats exposed first to the tandem schedule consisted mostly of paw contacts, which occurred at a lower rate at times other than shortly after food. Changing the schedule from fixed interval to tandem decreased the frequency of tongue contacts for all rats. Under schedules of food presentation with comparable interpellet intervals, the schedule of food presentation, rather than the rate of food delivery per se, determined the topography and temporal locus of drinking-tube contacts.     

An automated version of the digit symbol substitution test (DSST)

An automated version of the Digit Symbol Substitution Test is described that employs a relatively inexpensive, commercially available microcomputer to present and score the task. Advantages of the automated DSST include: (1) objective scoring of both speed and accuracy of test performance, (2) printed copies of test scores, (3) convenient administration under standardized test conditions, and (4) the capacity for repeated assessment of an individual’s performance over time. Task performance data for individual subjects following doses of pentobarbital are presented; these data illustrate both the stability of task performance under constant conditions and the within-subjects sensitivity of task performance to experimental manipulations.     

Locus of control and persistence in structured and unstructured preschool classrooms

The effect of locus of control and classroom structure on persistence and attention in preschool children was examined. Teachers' ratings of persistence were obtained for 16 children from a relatively structured classroom and for 18 children from a relatively unstructured classroom. Locus of control was measured by administering the Preschool and Primary Nowicki-Strickland Internal-External Scale (Nowicki & Duke, 1974). As predicted, teachers from the structured classrooms rated externally controlled children as more persistent (r=.55, p<.05), while teachers from the unstructured classroom rated internally controlled children as more persistent (r= -.35, p<.10). Practical implications of this line of research for making classroom placement decisions are discussed.     

The effectiveness of workplace counselling: A systematic review

Background: In response to the stresses of the contemporary workplace, the challenges of maintaining satisfactory work-life balance, and the costs to business of employee mental health problems, many organisations have contracted to make counselling services available to their staff. It is essential to evaluate the effectiveness of workplace counselling, in order to maintain standards, and to identify examples of good practice. Objectives: This paper presents a comprehensive, systematic review of the effectiveness of workplace counselling. Findings are analysed in terms of client satisfaction, psychological functioning, the meaning of work, work behaviour, and negative outcomes. Findings: Taken as a whole, the results of research suggest that counselling is generally effective in alleviating psychological problems, has a significant impact on sickness absence, and has a moderate effect on attitudes to work. Discussion: Methodological issues are discussed, and it is recommended that more high-quality research is required in order to reinforce the evidence base for workplace counselling in relation to a number of key questions.     

Attractor dynamics in word recognition: converging evidence from errors by normal subjects, dyslexic patients and a connectionist model

People make both semantic and visual errors when trying to recognise the meaning of degraded words. This result mirrors the finding that deep dyslexic patients make both semantic and visual errors when reading aloud. We link the results with the demonstration that a recurrent connectionist network which produces the meaning of words in response to their spelling pattern produces this distinctive combination of errors both when its input is degraded and when it is lesioned. The reason why the network can simulate the errors of both normal subjects and patients lies in the nature of the attractors which it develops as it learns to map orthography to semantics. The key role of attractor structure in the successful simulation suggests that the normal adult semantic reading route may involve attractor dynamics.     

Theoretical orientation and reported practice: A survey of eclecticism among counsellors in Britain

There is an increasing trend for counsellors to report that their practice is based on a combination of methods and approaches, rather than being grounded in a 'pure' model. However, there has been a lack of research on the proportion of counsellors in Britain who define themselves as eclectic or integrative in orientation. This study reports on a survey of eclecticism and integrationism in counsellors and other therapists in Britain. Results indicate that as many as 87% of counsellors can be regarded as taking a 'non-pure-form' approach of some kind. Issues in interpreting data on counsellors' self-reports of orientation are discussed, and implications for training and further research are outlined.
