A model of short-term counselling in primary care

Counselling in prima y care settings has received much interest throughout Britain. Many surgeries employ counsellors or psychologists as part of the primay health care team. This paper describes a model of primary care counselling using an example of a case encountered in general practice. It emphasizes the advantages of offering on-site counselling services, such as better possibilities of liaison with the referring doctor and coordination of patient care. Progress was made in seven sessions of short-term cognitive-behavioural treatment and a more stigmatizing referral (for example, to psychiatric services) was avoided. The case can be seen as an appropriate referral in the context of primay care counselling and illustrates the benefit of this approach to the treatment of psychological and social problems in general practice.

Discrete visual samples may control locomotor equilibrium and foot positioning in man

The static or dynamic visual cues required for equilibrium as well as for foot guidance in visually guided locomotion in man were studied using a variety of locomotion supports and illumination and visual conditions. Stroboscopic illumination (brief flashes) and intermittent lighting (longer flashes) were used to control and to vary the visual sampling frequency of static (positional/orientational) visual cues. There were three main findings: First, visual control of foot positioning during locomotion over a narrow support depends mainly upon the availability of high frequency static visual cues (up to about 12 Hz); and third, static visual cues required for equilibrium control are extracted from both the peripheral and the central visual field. Assuming that discrete demands for feedback occur, a simple probabilistic model was proposed, according to which the mean time that elapses following presentation of static visual cues about positions or changes of position accounts for the differences in the difficulty of the various illumination conditions.     

Development and Feasibility of a Group Cognitive-Behavioral Therapy for Fear of Cancer Recurrence

This paper describes the development, content, and preliminary results of a group cognitive-behavioral therapy (CBT) for fear of cancer recurrence (FCR). A manualized CBT intervention was developed and offered to 38 patients with various cancer types and stages in two hospitals. Four weekly group CBT sessions were administered by two licensed psychologists as part of routine care. Patients completed self-report scales before the first treatment session and, a second time, 1 month after the last session.Overall, 33 patients had clinical levels of FCR at baseline. The participants’ satisfaction toward the group CBT for FCR was high. Significant reductions on the total score and most subscales of the Fear of Cancer Recurrence Inventory (FCRI) were observed, as well as significant improvements on most of the other psychological variables measured (i.e., insomnia, anxiety, depression, dysfunctional beliefs about cancer, and intolerance of uncertainty). In addition, 52% of the patients with clinical levels of FCR (FCRI-severity subscale score ≥ 13) at baseline no longer reached this clinical threshold at posttreatment.These preliminary results suggest that our group CBT for FCR is well accepted and feasible, and shows promising efficacy for decreasing FCR and improving other psychological variables among cancer patients. The next step is to investigate the efficacy of this minimal intervention in larger and controlled clinical trials, as well as its usefulness as part of a stepped care approach.This low-cost intervention is easy to implement in various clinical settings and has a strong potential to help large numbers of patients with FCR.     

Time course of cardiac conditioned responses in restrained rats as a function of the trace CS-US interval

Two experiments aimed at understanding the temporal characteristics of trace-conditioned heart-rate responses to a 0.5-s tone (conditioned stimulus [CS]) in restrained rats. A CS paired with a tail-shock (unconditioned stimulus [US]) elicited lasting bradycardiac responses. The magnitude and extinction rate of conditioned responses (CR) were independent of the CS-US interval (interstimulus interval [ISI], 3 s to 20 s). Unreinforced test trials were analyzed for CR topography. Responding was delayed in groups with longer ISIs, but CR latencies, peak and decay times were not proportional to the ISI. Response peaks tended to cluster either about 6 s after CS onset, or about 10 s with a slow decay, depending on the ISI. The authors postulated 2 components of auditory stimulus traces involved in cardiac conditioning, maximally active 6 s and 10 s respectively after CS onset. The topography of the CR could be constrained to combinations of associative strength and instantaneous activity of these 2 components.     

Mothers' and fathers' depressive symptoms and conflict-resolution strategies in the marriage and children's externalizing and internalizing behaviors

The authors examined mothers' and fathers' avoidance and attacking conflict-resolution strategies in the marriage and their depressive symptoms as they related to children's externalizing and internalizing behaviors. A nonclinical community sample of 51 families and their children's 1st-grade teachers (N = 41) participated. Both mothers and teachers completed a behavior-problem checklist in order to evaluate the incidence of internalizing and externalizing behaviors in the children. Correlational statistics revealed significant associations between parents' avoidance and attacking strategies and their depressive symptoms. Also, parents' use of avoidance was related to more internalizing behaviors in the children. When hierarchical regression analyses were used to examine the contributions of the parents' attributes to children's externalizing and internalizing behaviors, mothers' avoidance and an interaction between mothers' and fathers' avoidance were identified as significant predictors of children's internalizing behaviors.     

Working memory capacity does not always promote dual-task motor performance: The case of juggling in soccer

The aim of this research was to refine our understanding of the role of working memory capacity (WMC) on motor performances that require attentional control in dual-task situations. Three studies were carried out on soccer players. Each participant had to perform a juggling task in both normal and dual-task conditions. In Study 1, the interfering task was a mental calculation test performed under time pressure (strong cognitive load). In Study 2, the interfering task was a count-down test (low cognitive load). In Study 3 an intra-individual design in which participants perform dual-tasks increasingly complex has been proposed. Results showed a positive relationship between participants’ WMC and their dual-task motor performance when the cognitive load was low and a negative relationship when the cognitive load was high. This paper highlights the role of the WMC in the activation of different modes of processing and its importance on the performance in dual-task.     

Integration of cardiac responses to serial stimuli after Pavlovian conditioning in rats

The expression of cardiac responses to sequences of two sounds was studied in restrained rats following discriminative trace or delay conditioning. Stimuli paired with a tail shock 10 sec later (CS1) elicited conditioned bradycardia. Unpaired or neutral stimuli (CS0) elicited mostly tachycardia. Rats did not learn to suppress responding to nonreinforced sequences with an interval of 6 sec between sounds. Responses to the second stimulus were significantly augmented following a CS1 stimulus, but not following a CS0 stimulus. Real-time summation of simple responses provided a more complete and quantitative prediction of dual responses than did resetting or facilitation. These results extend the time range over which summation may be observed from less than 2 sec to at least 16 sec. They appear to be inconsistent with models involving competition between unitary representations of stimuli in short-term memory and suggest the existence of multiple stimulus traces with independent time courses.
