Segregation in the classroom: What does it take to be accepted as a friend?

Research on students’ social relationships shows their preference to associate with similar peers. This study focused on the similarity in selection criteria used by students to form groups and similarity of characteristics of existing groups in schools. It compared these criteria to those of isolated students. The sample consisted of 124 students aged 14–15. The results revealed that the assessment of peers’ social skills was a relevant selection criterion, and that global self-esteem, well-being, and, physical activity were important variables in describing groups. The selection criteria and group characteristics of isolated students did not match those of the groups. The isolated students have more outspoken views on criteria and characteristics compared to the groups’ points of view.     

PyParse: A semiautomated system for scoring spoken recall data

Studies of human memory often generate data on the sequence and timing of recalled items, but scoring such data using conventional methods is difficult or impossible. We describe a Python-based semiautomated system that greatly simplifies this task. This software, called PyParse, can easily be used in conjunction with many common experiment authoring systems. Scored data is output in a simple ASCII format and can be accessed with the programming language of choice, allowing for the identification of features such as correct responses, prior-list intrusions, extra-list intrusions, and repetitions.     

Psychometric properties of the Psychosocial Risk Evaluation Battery for medium and small companies

The assessment of the presence and intensity of psychosocial risks is constant in research into Work Psychopathology. Many questionnaires and diagnosis systems are partial or else there is no standardization process or reliability and validity study. The main purpose of this work is to present the psychometric data of a multidimensional system to assess psychosocial risks, elaborated conjointly by the Universitat of Barcelona and the MC Mutual. This battery assesses companies, using information from the prevention technicians, the directive staff and the workers. With the diverse types of information, a triangulation proposal is established to offer a psychosocial risk profile linked to the evaluation needs.     

Note on Some Fixed Point Constructions in Provability Logic

We present a quite simple proof of the fixed point theorem for GL. We also use this proof to show that Sambin's algorithm yields a fixed point.     

Gamma oscillations distinguish true from false memories

ABSTRACT— To test whether distinct patterns of electrophysiological activity prior to a response can distinguish true from false memories, we analyzed intracranial electroencephalographic recordings while 52 patients undergoing treatment for epilepsy performed a verbal free-recall task. These analyses revealed that the same pattern of gamma-band (28–100 Hz) oscillatory activity that predicts successful memory formation at item encoding—increased gamma power in the hippocampus, prefrontal cortex, and left temporal lobe—reemerges at retrieval to distinguish correct from incorrect responses. The timing of these oscillatory effects suggests that self-cued memory retrieval begins in the hippocampus and then spreads to the cortex. Thus, retrieval of true, as compared with false, memories induces a distinct pattern of gamma oscillations, possibly reflecting recollection of contextual information associated with past experience.     

A method for the control of eating rate: A potential intervention in eating disorders

A method for the control of eating rate gave subjects feedback from a computer screen on how much and at what rate to eat during a meal. The method also allowed us to record the development of satiety during the meal. Linear eaters—that is, women selected for eating at an approximately constant rate—underate when challenged to eat at a lower rate and overate when challenged to eat at a higher rate, thereby modeling the eating behavior of patients with anorexia nervosa and binge eating disorder, respectively. In both cases, the women’s postmeal perception of satiety mimicked that of the respective patient group. The results provide support for the notion that linear eaters have the capacity to exhibit disordered eating.     

Fired managers: Experiences from their own unemployment

This paper purports to enhance the understanding of stress and its effects on unemployed executives. The idea that unemployed managers perceive and confront stress differently from their employed colleagues is addressed. A sampling of 32 unemployed executives and managers was taken using The Stress Profile, to survey reasons for stress, coping ability, and response to stress. The profiled samples were then compared to a comparison group of 367 employed managers. The results showed that unemployed managers, when compared to their employed associates, tended to have less desireable family situations, more worries about finances, decreased perception of self and self-coherence, decreased coping ability, and heightened emotional and behavioral reaction to stress. The conclusion was that when dealing with stressors, unemployed managers experienced a decreased sense of psychological well-being and coping abilities as compared to employed managers.     

Siblings in family therapy

The participation of siblings in family therapy was studied from case records in 76 consecutive cases attending a child and adolescent psychiatric outpatient clinic. Siblings took part in family therapy in two thirds of the cases. Of these, 76 per cent attended only one or two sessions. A sub-sample of nine families with children below 13 years of age was interviewed. Seven out of 10 evaluated siblings had psychiatric symptoms of some severity at the onset of therapy compared to two after, and all had fewer symptoms after therapy compared to before (p<0.01). Most families thought it relevant for both parents and siblings to take discussing their children's behaviour in front of them and wanted the opportunity of also talking to the therapist without the children being present.     

The psychological treatment of tinnitus: An experimental evaluation

Disabling tinnitus in 27 patients was treated in an experimental setting with two different types of therapy aiming at the development of coping behaviour. One was focused on behavioural control procedures, while the other aimed at more cognitive control methods such as distraction. The results of the two forms of therapy were compared with each other and with observations of the untreated control subjects. Assessments of subjective loudness, discomfort from tinnitus and controllability were made on analogue scales and at a questionnaire follow-up. Psychoacoustic measures such as personal loudness units (PLU) were used in connection with these self-recordings and for evaluation of treatment effects. The results confirmed favourable reports on behavioural methods in tinnitus. However, no differences were found between therapies. The results are discussed in the light of the coping and adaptation theory.
