Effortful control, executive attention, and emotional regulation in 7–10-year-old children

In this study, self-regulation was investigated in 7- to 10-year-old children using three different measures: (1) parent and child report questionnaires measuring temperamental effortful control, (2) a conflict task assessing efficiency of executive attention, and (3) the mistaken gift paradigm assessing social smiling in response to an undesirable gift. Both efficiency in executive attention and smiling to the undesired gift increased over age. Executive attention was related to both parent-reported temperamental effortful control and smiling, suggesting links between attentional capacities, broad temperament measures, and social situations requiring attentional control.     

Evaluation of Siddha Samadhi Yoga for anxiety and depression symptoms: a preliminary study

Siddha Samadhi Yoga is a program in which meditation is associated with pranayama (breathing exercises). 22 volunteers with anxiety complaints (M age = 42.8 yr., SD = 10.3) were assigned to two groups: 14 attended the yoga group, and 8 attended a waiting-list or control group. They were evaluated before the intervention and 1 month after it on the State-Trait Anxiety Inventory, the Beck Depression Inventory, Tension Feelings Self-evaluation Scales, and the Well-being Self-evaluation Scales. A significant reduction in scores on anxiety, depression, and tension was found in yoga group, as well as an increase in well-being in comparison with the control group.     

Gender, Video Game Playing Habits and Visual Memory Tasks

The current research examined whether visuospatial recall of both abstract and common objects was related to gender or object familiarity. Seventy two undergraduates from a university in the Southern U.S. were asked to draw the Rey Complex Figure and a series of common objects from memory. A pilot sample of seventy three undergraduates had previously identified common objects as “male” “female” and “neutral” exemplars. Males were significantly better at drawing “male” and “neutral” exemplars whereas females were better at drawing “female” exemplars. Neither gender was significantly better at the Rey task. These results question whether males have an inherent advantage in visual memory. Results also found that experience with playing violent video games was associated with higher visual memory recall.     

Differential effects of instructions and consequences on human conditional discrimination performance

Two studies evaluated the differential behavioral effects of instructions and feedback in matching-to-sample procedures. In Experiment 1, 20 college students received true or false instructions and trial-by-trial or delayed feedback in three phases. In a fourth, final phase the instructions remained the same, but feedback changed from trial-by-trial to delayed, or from delayed to trial-by-trial. In Experiment 2, half of another 20 participants received true instructions during three phases, followed by false instruction in a fourth phase; the other half of the participants received false instructions during three phases, followed by true instructions in the fourth phase. Feedback sequences were as in Experiment 1. The results of both experiments revealed historical effects of instructions and feedback. Most participants demonstrated strong instructional control, overriding the control by contingencies. These results suggest that the present procedure offers optimal possibilities to make the differential effects of instructions and feedback on human behavior clearly identifiable when conditional discrimination tasks are used.     

Personalidad,diferencias individuales y decisión con riesgo

Resumen

Esta investigación trata de comprobar si existen diferencias individuales en las estrategias usadas en las tareas de decisión con riesgo que puedan ser explicadas en términos de rasgos polares de personalidad (neuroticismo y extroversión). Al mismo tiempo se trata de encontrar evidencia de las causas (no explicadas) que podrían justificar la clasificación de estrategias propuesta desde la teoría de la integración de la información. Este artículo consta de dos partes bien diferenciadas, en la primera se lleva a cabo un experimento donde los datos no apoyan que los rasgos de personalidad usados expliquen las diferencias individuales; se encontró apoyo para tres de las estrategias descritas en integración de la información. En la segunda parte, con el propósito de analizar las diferencias individuales en el tiempo, se muestra que la estructura lógica del sujeto, como procesador/decisor, es relativamente invariante en el tiempo. Finalmente se discute si la naturaleza de la tarea experimental obliga a los sujetos a desarrollar estrategias ad hoc con poco claro valor de generalización.
