Reliability and Validity Analyses of the Self-Management Questionnaire

The authors developed a parent-report measure to enhance findings for diagnoses and evaluations, and therefore, improve on the assessments currently being widely used for this purpose. Data were gathered on 322 clients (4–18 years old) seeking treatment at a private practice setting. Factor analysis revealed 18 subscales. Scores were internally consistent and distinct from other subscales. In addition, the questionnaire showed good diagnostic utility for depression, Oppositional Defiant Disorder (ODD), and Pervasive Developmental Disorder (PDD). This study provides sufficient evidence of the reliability and validity of the Self-Management Questionnaire (SMQ) to recommend its use for skills and needs assessment with children and adolescents.     

Dissociable effects of basolateral amygdala lesions on decision making biases in rats when loss or gain is emphasized

Individuals switch from risk seeking to risk aversion when mathematically identical options are described in terms of loss versus gains, as exemplified in the reflection and framing effects. Determining the neurobiology underlying such cognitive biases could inform our understanding of decision making in health and disease. Although reports vary, data using human subjects have implicated the amygdala in such biases. Animal models enable more detailed investigation of neurobiological mechanisms. We therefore tested whether basolateral amygdala (BLA) lesions would affect risk preference for gains or losses in rats. Choices in both paradigms were always between options of equal expected value—a guaranteed outcome, or the 50:50 chance of double or nothing. In the loss-chasing task, most rats exhibited strong risk seeking preferences, gambling at the risk of incurring double the penalty, regardless of the size of the guaranteed loss. In the betting task, the majority of animals were equivocal in their choice, irrespective of bet size; however, a wager-sensitive subgroup progressively shifted away from the uncertain option as the bet size increased, which is reminiscent of risk aversion. BLA lesions increased preference for the smaller guaranteed loss in the loss-chasing task, without affecting choice on the betting task, which is indicative of reduced risk seeking for losses, but intact risk aversion for gains. These data support the hypothesis that the amygdala plays a more prominent role in choice biases related to losses. Given the importance of the amygdala in representing negative affect, the aversive emotional reaction to loss, rather than aberrant estimations of probability or loss magnitude, may underlie risk seeking for losses.     

Performing a secondary executive task with affective stimuli interferes with decision making under risk conditions

Previous studies demonstrated that executive functions are crucial for advantageous decision making under risk and that therefore decision making is disrupted when working memory capacity is demanded while working on a decision task. While some studies also showed that emotions can affect decision making under risk, it is unclear how affective processing and executive functions predict decision-making performance in interaction. The current experimental study used a between-subjects design to examine whether affective pictures (positive and negative pictures compared to neutral pictures), included in a parallel executive task (working memory 2-back task), have an impact on decision making under risk as assessed by the Game of Dice Task (GDT). Moreover, the performance GDT plus 2-back task was compared to the performance in the GDT without any additional task (GDT solely). The results show that the performance in the GDT differed between groups (positive, negative, neutral, and GDT solely). The groups with affective pictures, especially those with positive pictures in the 2-back task, showed more disadvantageous decisions in the GDT than the groups with neutral pictures and the group performing the GDT without any additional task. However, executive functions moderated the effect of the affective pictures. Regardless of affective influence, subjects with good executive functions performed advantageously in the GDT. These findings support the assumption that executive functions and emotional processing interact in predicting decision making under risk.     

The nature of altered vision near the hands: Evidence for the magnocellular enhancement account from object correspondence through occlusion

A growing body of evidence indicates that the perception of visual stimuli is altered when they occur near the observer’s hands, relative to other locations in space (see Brockmole, Davoli, Abrams, & Witt, 2013, for a review). Several accounts have been offered to explain the pattern of performance across different tasks. These have typically focused on attentional explanations (attentional prioritization and detailed attentional evaluation of stimuli in near-hand space), but more recently, it has been suggested that near-hand space enjoys enhanced magnocellular (M) input. Here we differentiate between the attentional and M-cell accounts, via a task that probes the roles of position consistency and color consistency in determining dynamic object correspondence through occlusion. We found that placing the hands near the visual display made observers use only position consistency, and not color, in determining object correspondence through occlusion, which is consistent with the fact that M cells are relatively insensitive to color. In contrast, placing observers’ hands far from the stimuli allowed both color and position contribute. This provides evidence in favor of the M-cell enhancement account of altered vision near the hands.     

The Mind of the Scenario Thinker

In the face of increasing uncertainty and changes, corporations must dynamically examine their business environment and activate the knowledge creation process in a future-oriented manner without getting hung up on analyzing their past (much like driving a car using only the rear-view mirror). In the previous article, we discussed the basics of scenario planning. We should not use this tool as a mere technique. Our knowledge of the world and the environment around us is important because it underlies our scenarios. When we look toward the future in an uncertain environment, we necessarily create knowledge proactively. Scenario planning and knowledge creation are commonplace when working on knowledge of innovations that shape the future. In this article we focus on the importance of having “scenario mind,” the philosophy underlying scenario planning. With any managerial tool, you cannot create real knowledge if you use only superficial know-how, like procedures described in manuals, to seek quick results. In the following sections, we discuss how scenario planning must be recognized as a “discipline of knowledge” to be embedded as a way of thinking and behavioral pattern of each individual or organization, not as a mere tool.

A Preliminary Evaluation of Functional Communication Training Effectiveness and Language Preference When Spanish and English are Manipulated

We evaluated whether differences in treatment effectiveness or preference between languages emerged across Spanish and English during functional communication training (FCT) for young children with developmental disabilities exposed to Spanish and English in the home environment. Participants were 2 young children with developmental disabilities who displayed destructive behavior maintained by social contingencies and whose families spoke Spanish and English at home. All procedures were conducted in the participants’ homes by their mothers with coaching from the investigator. The effectiveness of FCT was evaluated within a reversal design across baseline, FCT, and extinction conditions. A multielement design across language type (Spanish and English) was embedded within the reversal design during the extinction and FCT conditions to evaluate differences in treatment effectiveness across type of language. Finally, during all FCT sessions, a concurrent schedules design was used to evaluate participant preference for type of language. Results suggested that FCT was effective in reducing destructive behavior, increasing manding, and/or increasing task completion for these 2 participants across Spanish and English treatment conditions. Preference for the type of language did not emerge for either participant during FCT. Results are discussed in terms of the merits of systematically evaluating language variables when working with culturally and linguistically diverse families and children.     

Seeing while acting: hand movements can modulate attentional capture by motion onset

The onset of new motion has been shown to be a very robust cause of attentional capture, generating a processing advantage for the location of motion onset regardless of the observer's concurrent goal. The present study, motivated by the common-coding account of action and perception, examined whether the effect of motion onset on visual attention can be modulated by the observer's mode of action. Specifically, the common-coding account predicts that preparing an action can render the features that are used in the action plan less available for visual processes. Consistent with this hypothesis, in Experiment 1 the magnitude of attentional capture caused by a single motion onset was reduced when this motion was similar to the observer's response (i.e., along the same axis). Similarly, in Experiment 2 the onset of a response-different motion gained a processing advantage over the response-similar motion onset when the two were presented simultaneously. Since both types of motion were present in every trial, the results of Experiment 2 suggest that response similarity affected visual-attentional processes rather than motor processes. Together, these results suggest that the processes of attentional prioritization caused by motion onset can be modulated by the observer's concurrent action.
