Achievement and social goals, persistence-effort, and intentions of sport practice in physical education students

The present study examined the relationship between achievement and social goals, and explored how both types of goals can affect secondary school students' persistence/effort in Physical Education classes, as well as their intention to participate in sport activities after finishing secondary school. A sample of 350 students (aged 15-17) from two high schools in Asturias participated in the study. Multiple regression analysis showed: a) persistence/effort in physical education classes was better explained by social responsibility goals, followed by mastery-approach goals and mastery-avoidance goals; b) achievement goals are the only predictors of young people's intention of practicing sport in the future. Differences were found in these results according to gender and course. These findings help us better understand the processes involved in Physical Education. Finally, implications to improve classes and to achieve young people's more active and higher level of implication in sports are discussed.     

Antidepressant discontinuation in the context of cognitive behavioral treatment for panic disorder.

Cognitive behavioral treatment (CBT) has been shown to reduce risk for adverse reactions (e.g., rebound panic) following benzodiazepine taper for patients with panic disorder (PD). This study evaluated the effects of antidepressant discontinuation for patients with PD in the context of CBT. Patients with PD (n=21) on a stable dose of antidepressants completed a 12-week group CBT treatment and were randomly assigned to discontinue antidepressants during week 8 of the treatment. There were no statistically significant differences between groups at posttreatment or 6-month follow-up. Data indicate no apparent immediate or long-term adverse effects for antidepressant discontinuation for patients with PD receiving CBT.     

Successive negative contrast after partial reinforcement in the consummatory behavior of rats

Rats given access to a 32% sucrose solution later reject a 4% solution significantly more than controls that have only received the 4% solution. In Experiment 1, this consummatory successive negative contrast (cSNC) effect was attenuated by previous exposure to 50% partial reinforcement. Furthermore, recovery from cSNC was also facilitated by partial reinforcement. In Experiment 2, the attenuating effects of partial reinforcement on cSNC were eliminated by administration of the benzodiazepine anxiolytic chlordiazepoxide (5 mg/kg) before nonreinforced trials. In Experiment 3, the attenuating effect of partial reinforcement was greater after a shift from 32 to 6% solution, than after a shift from 32 to 2% solution. The parallels between the effects of partial reinforcement on consummatory and instrumental behavior are discussed.     

Contrasting vertical and horizontal representations of affect in emotional visual search

Independent lines of evidence suggest that the representation of emotional evaluation recruits both vertical and horizontal spatial mappings. These two spatial mappings differ in their experiential origins and their productivity, and available data suggest that they differ in their saliency. Yet, no study has so far compared their relative strength in an attentional orienting reaction time task that affords the simultaneous manifestation of both types of mapping. Here, we investigated this question using a visual search task with emotional faces. We presented angry and happy face targets and neutral distracter faces in top, bottom, left, and right locations on the computer screen. Conceptual congruency effects were observed along the vertical dimension supporting the ‘up = good’ metaphor, but not along the horizontal dimension. This asymmetrical processing pattern was observed when faces were presented in a cropped (Experiment 1) and whole (Experiment 2) format. These findings suggest that the ‘up = good’ metaphor is more salient and readily activated than the ‘right = good’ metaphor, and that the former outcompetes the latter when the task context affords the simultaneous activation of both mappings.     

Effects of the iodine deficiency on intellectual variables among children

An association between severe iodine deficiency and poor mental development has been found in many studies. We examined the relationship between moderate or mild iodine deficiency and intellectual capacity in order to determine whether problems common to severe iodine deficiency (including mental retardation) also emerge in a more subtle form. We also wished to know whether the classic methodology (comparing iodine-deficient zones with nondeficient zones) is the most adequate, and propose to combine this grouping by zones with urinary iodine presented by individuals in each zone. We measured IQ, manipulative and verbal capacity, attention, visual motor ability and disruptive behaviour, variables that have barely been studied in this kind of investigations. The sample comprised 760 schoolchildren from the province of Jaén (southern Spain). Our results show that children with low levels of iodine intake and with urinary iodine concentration lower than 100 microg/litre had a lower IQ and displayed more disruptive behaviour than children with high levels of the criteria. The other variables were not associated with iodine deficiency.     

Brightness contrast: a reinterpretation of compound cue and combined cue experiments with pigeons.

A group of three pigeons was trained on a 4-ply multiple schedule: a green color and a vertical line superimposed upon an achromatic background as positive stimuli, and a red color and a horizontal line on an achromatic background as negative stimuli. The pigeons were tested with the vertical line superimposed upon different achromatic background intensities, then with the vertical line superimposed upon different green background intensities, and finally with the vertical line and its training achromatic backgfound attenuated (and unattenuated) by a neutral density filter. The gradients peaked at the luminance of the achromatic background used during training and at the equivalent luminance for the green background when it was substituted for the achromatic background. The brightness contrast, not the background luminance, was the critical variable as the neutral density filter attenuated both the line and the background equally, leaving brightness contrast unchanged; there was no response decrement to this attenuated stimulus. Two other groups of three pigeons showed that they attended to line orientation as well as to brightness contrast. The brightness contrast hypothesis was extended to explain results of attention experiments and combined cue experiments which have used line stimuli in combinations with different backgrounds.     

Comportements d’automédication et infirmières Recherche qualitative exploratoire

In everyday life, self-medication is a usual mean of self-care either with drugs or alternative medicines that calls for attention from health psychologists. The aim of this qualitative study is to explore and understand self-medication among experts in the health and illness world. Semi-structured interviews with nurses have been analysed using Grounded Theory model. Results show that self-medication is a pragmatic behaviour embedded in the history of the individual, sensitive to his socioeconomic and professional context. As experts for their own health, nurses’ strategies to deal with their minor ailments raise the question of “pharmacologisation” of everyday life.
