Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms

Smári, J., Rúrik Martinsson, D., & Einarsson, H. (2010). Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms. Scandinavian Journal of Psychology, 51, 392–397. The aim of the study was to investigate potential precursors of inflated responsibility (responsibility attitudes) and obsessive‐compulsive (OCD) symptoms. It was argued that both parental overprotection and impulsivity, separately and in interaction with each other, contribute to inflated responsibility and OCD symptoms. In a large sample of young adults (N = 570), self‐report measures of OCD symptoms (OCI‐R), responsibility attitudes (RAS), anxiety/depression (HADS), rearing practices (EMBU), present and past impulsivity/hyperactivity symptoms (IMP/HY) were administered. Overprotection as well as IMP/HY were found to predict OCD symptoms as well as inflated responsibility. Finally, a significant interaction was found between IMP/HY and overprotection with regard to both OCD symptoms and inflated responsibility. This effect reflected that IMP/HY was more strongly related to OCD symptoms and responsibility in people who had not been overprotected than in people who had been. Conversely overprotection was related to OCD symptoms and responsibility in people low but not in people high in IMP/HY. The results seem to indicate that the inadequacy between offer and need for parental control may play a role in the development of OCD symptoms.     

Non-standard Stochastics with a First Order Algebraization

Internal sets and the Boolean algebras of the collection of the internal sets are of central importance in non-standard analysis. Boolean algebras are the algebraization of propositional logic while the logic applied in non-standard analysis (in non-standard stochastics) is the first order or the higher order logic (type theory). We present here a first order logic algebraization for the collection of internal sets rather than the Boolean one. Further, we define an unusual probability on this algebraization.     

Structural relaxation and rejuvenation in a metallic glass induced by shot-peening

The metallic glass Pd₄₀Cu₃₀Ni₁₀P₂₀ in as-cast or pre-annealed states was shot-peened successively at room temperature or at 77 K. The structural state of the glass was characterized by the relaxation spectrum measured in a differential scanning calorimeter. Mechanically induced relaxation of the as-cast glass and mechanically induced rejuvenation of pre-annealed samples are both more evident at 77 K than at 298 K, enabling deductions about the underlying mechanisms. The relaxation spectrum of the glass as a function of temperature displays two broad maxima, which occurring at the higher temperature is attributed to the part of the free-volume distribution associated with flow defects. In samples shot-peened at 77 K, the stored energy after deformation can be as high as 20% of the cold work. Shot-peening simultaneously generates flow defects within shear bands and destroys them in the matrix between bands: whose effect dominates is principally dependent on the initial state of relaxation of the glass. Shot-peening of partially crystallized samples appears capable of breaking up and dispersing crystallites without inducing any further significant crystallization.     

Are You Really Happy? Children’s Understanding of Real vs. Pretend Emotions

This paper studies children’s capacity to understand that the emotions displayed in pretend play contexts do not necessarily correspond to internal emotions, and that pretend emotions may create false beliefs in an observer. A new approach is taken by asking children about pretend emotions in terms of pretence-reality instead of appearance-reality. A total of 37 four-year-olds and 33 six-year-olds were asked to participate in tasks where they had to pretend an emotion or where they were told stories in which the protagonists pretended an emotion. In each task children were asked: a) if the pretend emotion was real or just pretended and b) if an observer would think that the emotional expression was real or just pretended. Results showed that four-year-olds are capable of understanding that pretend emotions are not necessarily real. Overall, six-year-olds performed better than younger children. Furthermore, both age groups showed difficulty in understanding that pretend emotions might unintentionally mislead an observer. Results are discussed in relation to previous research on children’s ability to understand pretend play and the emotional appearance-reality distinction.     

The Effects of Eight-Month Physical Activity Intervention on Vigilance Performance in Adult Obese Population

We aim to analyze the effects of an 8-month physical activity intervention on cardiorespiratory fitness, body mass index (BMI), and vigilance performance in an adult obese population. We conducted an 8-month physical activity intervention based on dance and rhythmic activities. The weekly frequency was 2 sessions of 1 hr per day. Training sessions were divided into 3 phases: a 10-min warm-up, 40 min of dance and rhythmic activities, and 10 min to cool-down. To assess cardiorespiratory fitness, participants performed a modified version of the 6-min walk test from the Senior Fitness Test battery (Larsson & Mattsson, 2001; Rikli & Jones, 1999). Vigilance performance was measured by means of the psychomotor vigilance task (PVT). Two measurements were performed immediately before and after the intervention. The results revealed that participants improved their cardiorespiratory fitness, BMI, and vigilance performance after the intervention. All in all, findings contribute new empirical evidence to the field that investigates the benefits of physical activity intervention on cognitive processes in obese population.     

Deviance‐construction in Stalinist societies: A critical analysis

This study is concerned with the definition of deviance and the processes of constructing deviance in Stalinist societies. Deviances created by the state in these societies are analyzed, especially from functionalist and phenomenologist aspects and by applying Foucault's approach. Solzhenitsyn's Gulag Archipelago is used as a starting point for the analysis. In his work, Solzhenitsyn dwells at length on the “deviances” and the process of deviance construction in Stalinist Soviet Union. It is suggested that, in these societies, “total state deviance” fits in a desacralized, demodernized world view. Finally some consequences of this deviance image still at work are discussed.     

Contextual Variations of Infrahumanization: The Role of Physical Context and Territoriality

The malleability of the infrahumanization bias was tested varying the physical context in which the ingroup and the outgroup target were assessed. Using a sequential priming paradigm, Study 1 replicated the infrahumanization bias in a neutral context. Study 2 tested the hypothesis that there are contextual variations in infrahumanization. Specifically, Black targets were infrahumanized in a context familiar to White participants, and not in an unfamiliar context. Study 3 revealed that participants’ threat perceptions were reduced when ingroup targets appeared in familiar context, compared to Black targets. Theoretical implications for the infrahumanization bias are discussed.     

Paisaje y personalidad

Resumen

Esta investigación se presenta con la idea de plasmar la posible relación existente entre las diferencias individuales de sexo y personalidad y las preferencias por determinados tipos de paisaje. La hipótesis de partida es que la estructura de la personalidad condiciona la elección del paisaje, influencia que puede ser directa o mediada por factores de personalidad. Dicha hipótesis ha sido probada para tres componentes de paisaje: I) Paisaje natural versus humanizado. II) Paisaje acogedor versus inhóspito. III) Formas rectas y netas versus difusas y redondeadas     

Psicología Diferencial, ¿Ciencia o Tecnología?

RESUMEN

En este trabajo Antonio Caparrós analiza, desde el punto de vista de la historia y epistemología de la psicología, el enfoque de Royce, Forteza y Prieto acerca del “status” científico de la Psicología Diferencial. El autor sintetiza en nueve puntos sus reflexiones, manifiestando que el proyecto completo de la Psicología Diferencial debe situarse más en el marco de las necesidades tecnológicas, cuyos fines específicos no son como los de los paradigmas explicativos de la ciencia en sentido estricto. Los dos últimos puntos se reservan al análisis de las interacciones entre ciencia y tecnología a lo largo de la historia, que contribuye a aclarar las relaciones entre algunos de los modelos de la psicología general y/o experimental y otros diferenciales.     

El tratamiento de la impulsividad infantil: Autoinstrucciones versus solución de problemas

Resumen

El objetivo del presente trabajo es comparar la eficacia de dos tratamientos, Autoinstrucciones (AI) y Solución de Problemas (SP), en la reducción de la impulsividad infantil y la mejora del rendimiento escolar. Alumnos impulsivos (seleccionados a partir del MFF-20) de cuarto y quinto de EGB (n = 18) fueron asignados a una de las dos condiciones de tratamiento, de dieciocho sesiones, o a un grupo control. Los resultados indican una superior eficacia del tratamiento de SP, ya que las latencias sobre el test MFF-20 aumentaron (p <.01) Y además, tanto en latencias como en errores, diferían de los otros dos grupos al terminar el tratamiento (p <.01). En cuanto al rendimiento escolar, los efectos de ambos tratamientos han sido mínimos, aunque sugieren también cierta superioridad del SP. Estos resultados señalan la necesidad de analizar en los programas multicomponentes el grado de contribución de cada procedimiento a la reducción de la impulsividad, concretamente el componente AI no parece contribuir decisivamente a ello.
