The effects of S-R uncertainty in the PRP paradigm: A reply to Kantowitz

Karlin and Kestenbaum (1968) reported a series of apparently complex interactions between S-R uncertainty and RT in an experiment using the psychological refractory period paradigm. McLeod (1977) showed that these effects could be predicted by a parallel processing limited capacity model. Kantowitz (1978) criticised that paper on the grounds that it paid insufficient attention to the predictions of response conflict theory and made no mention of errors.It will be shown (a) that response conflict theory, as described by Kantowitz, fails to predict the effects found by Karlin and Kestenbaum (b) that the comments about errors miss the point of McLeod (1977) (c) that in his final section Kantowitz falls into an old trap which awaits the unwary analyser of PRP data.     

Therapeutic Factors Experienced by Members of an Out-Patient Therapy Group for Older Women

The Yalom curative factors Q-sort was administered to eight members of an out-patient therapy group for older women (average age 55 years), who were also interviewed on the group experiences they had viewed as helpful. Results indicated that Existential Awareness was seen as the most important curative or therapeutic mechanism by members of this group. This finding stands in contrast to other studies of out-patient groups, in which interpersonal factors have been widely reported as most helpful. The reasons for this distinctive finding are examined. Results also exhibited striking individual differences between members of the group in terms of the group processes they each found most therapeutic. The significance of these findings is discussed, both in relation to working with older women, and also with respect to methodological issues concerned with the use of the Yalom Q-sort technique.     

The relationship between personal philosophy and effectiveness in counsellors

This study investigates the relationship between the effectiveness of counsellors and their personal philosophy, beliefs and attitudes. There is a review of the relevant literature concerning the qualities and attributes of effective counsellors, with a detailed examination of studies of counsellor philosophy. Two groups (n = 14 and n = 19) of counsellors on training courses were studied. Each participant wrote an account of a ‘Helping Relationship Incident’ which was rated on the 12 dimensions of counsellor ‘perceptual organization’ developed by Combs & Soper (1963). Course tutors gave ratings of the counselling effectiveness of their students. Rank order correlations between judgements of counsellor effectiveness and ratings of perceptual organization/philosophy were made. In both groups statistically significant results were found, adding weight to the hypothesis that a ‘person-centred’ perceptual organization or belief system is an important factor in counsellor effectiveness. The implications for counsellor selection and training are discussed, and suggestions are made for further research on this topic.     

Connectionist Modelling of Word Recognition

Connectionist models offer concretemechanisms for cognitive processes. When these modelsmimic the performance of human subjects theycan offer insights into the computationswhich might underlie human cognition. We illustratethis with the performance of a recurrentconnectionist network which produces the meaningof words in response to their spellingpattern. It mimics a paradoxical pattern oferrors produced by people trying to read degradedwords. The reason why the network produces thesurprising error pattern lies in the nature ofthe attractors which it develops as it learns tomap spelling patterns to semantics. The keyrole of attractor structure in the successfulsimulation suggests that the normal adult semanticreading route may involve attractor dynamics, andthus the paradoxical error pattern isexplained.     

Temporal Variation in Adolescent Suicide Attempts

The purpose of this study was to examine the association between adolescent suicide attempts and temporal cycles in a multiethnic population. Medical records at two hospitals in the state of Hawaii were reviewed for all adolescents (ages 12–18) admitted for suicide attempts during the years 1987–1991. Results showed 296 adolescents attempted suicide, and as hypothesized, temporal factors were associated with the attempts. A significant increase in attempts was found during the afternoon/evening and on Mondays and Tuesdays, transition points between home and school. The results are discussed and implications for delivery and temporal theory development considered.     

Research on embedded counselling: An emerging topic of potential importance for the future of counselling psychology

A significant proportion of the counselling that people receive takes place within informal, situated encounters between service users and practitioners in fields such as nursing, medicine, teaching and social work. However, almost all of the research that has been carried out into the process and outcomes of counselling consists of studies of formal, contracted counselling and psychotherapy based in therapy clinics and offices. The competent and effective delivery of counselling that is embedded in a primary professional role, such as that of nurse, teacher or social worker, presents considerable challenges for practitioners. Research evidence around the process and outcomes of embedded counselling represents a valuable resource that has the potential to enhance the quality of counselling conversations enacted by practitioners in health, education, social work and other professions. An overview is provided of different types of research that has been carried out into informal and embedded counselling, and of the main themes that have emerged from these studies. Suggestions are made for the further development of this field.

Preserved and Impaired Detection of Structure From Motion by a 'Motion-blind" Patient

Following bilateral extrastriate damage to areas that include the suspected human homologue of V5/MT, the patient LM has a specific deficit in processing moving stimuli. She has difficulty detecting the movement or coding the velocity of single moving dots. Nevertheless, we find that she can report human actions in Johansson “biological motion ”; displays. This requires the accurate coding of the direction and velocity of many moving dots. The implication is that structure can be extracted from motion in regions of visual cortex other than those traditionally associated with motion processing. However, she cannot report the spatial disposition of the actors whose actions she has recognized, not their movement in depth relative to her. A possible interpretation is that coding in these additional regions is primarily object-centred. Adding a small number of random stationary “noise” dots to the display prevents her from identifying the actions, suggesting that segregation by motion is implemented within the traditional movement areas.
