A longitudinal analysis of the attention networks in 6- to 11-year-old children

Attention is critical for everyday functioning. Posner and Petersen’s model of attention describes three neural networks involved in attention control—the alerting network for arousal, the orienting network for selecting sensory input and reorienting attention, and the executive network for the regulatory control of attention. No longitudinal research has examined relative change in these networks in children. A modified version of the attention network task (ANT) was used to examine changes in the three attention networks, three times over 12 months, in 114 6-, 8- and 10-year-olds. Findings showed that the alerting network continued to develop over this period, the orienting network had stabilized by 6 years, and the conflict network had largely stabilized by 7 years. The reorienting of attention was also assessed using invalid cues, which showed a similar developmental trajectory to the orienting attention network and had stabilized by 6 years. The results confirm that age 6 to 7 years is a critical period in the development of attention, in particular executive attention. The largest improvement over the evaluation period was between 6 and 7 years; however, subtle changes were found in attention beyond 8 years of age.     

Asking the Right Questions About g

It is our position that a complete understanding of human intellectual development is of ultimate interest to researchers and of great import to society. In this article, we ask questions that reflect common themes seen in the debate regarding the nature and importance of general cognitive ability (i.e., the g factor), sources of individual and group differences, and the viability of arguments against g theory. We also examine questions reflecting aspects of these debates that are commonly ignored or misconstrued. Our goal is to help researchers and debaters continue or begin to ask clear, critical, and dispassionate questions about g that will stimulate productive research and promote informed public policy.     

Spatial memory and executive functions in children

A computerized hidden pathway maze-learning task was used to examine the development of spatial memory and executive functions in 6- to 9-year-olds. Pathway length was manipulated to investigate the impact of increases in maze matrix size on these abilities. Analysis showed that maze matrix size (and ipso facto pathway length) and age interacted to affect executive functions but not spatial memory. Executive errors differed as a function of age on the most difficult maze. Results are discussed in terms of factors affecting the development of executive functions and spatial memory.     

Using stimulus control procedures to teach indoor rock climbing to children with autism

The present study evaluated an intervention package for teaching route following to two children with autism at an indoor rock‐climbing gym. The intervention consisted of multiple within‐stimulus fading procedures in combination with errorless learning procedures, positive reinforcement, an error correction procedure, and conditional discrimination training technologies. The results demonstrated that both participants learned to climb at least 10 ft/3 m on specified routes. Furthermore, both participants learned to climb an entire 22‐ft/6.7‐m wall for at least one of three different routes without any errors in a regular rock‐climbing gym setting. The acquisition of this skill provides children with autism with an additional option for leisure participation with others. Copyright © 2010 John Wiley & Sons, Ltd.     

Enhancing Students' Engagement by Increasing Teachers' Autonomy Support

Engagement refers to the behavioral intensity and emotional quality of a person's active involvement during a task. Recognizing the benefits highly engaged people experience, we tested whether classroom teachers could incorporate the relatively foreign concept of autonomy support into their motivating styles as a way to promote their students' engagement during instruction. Teachers in an experimental group and teachers in a delayed-treatment control group received information and guidance consistent with self-determination theory on how to support students' autonomy. Over a series of 3 classroom observations, trained raters scored each teacher's autonomy support and 2 measures of their students' engagement–task involvement and influence attempts. Trained teachers displayed significantly more autonomy-supportive behaviors than did nontrained teachers. Further, the more teachers used autonomy support during instruction, the more engaged were their students. This was true on both measures of engagement.     

Providing a Rationale in an Autonomy-Supportive Way as a Strategy to Motivate Others During an Uninteresting Activity

When motivating others during uninteresting activities, people typically use extrinsic contingencies that promote controlling forms of extrinsic motivation. In contrast, we investigated a motivational strategy that could support another person's capacity to personally endorse and value the effort he or she put forth during the uninteresting activity. That strategy is the provision of an externally provided rationale when communicated in an autonomy-supportive way. In two studies, we tested and found support for a motivational mediation model, based on self-determination theory, in which the presence of such a rationale (vs. its absence) adds to participants' identification with the task's personal value which, in turn, explains participants' subsequent effort. These studies suggest that extrinsically motivated behaviors can become self-determined through the process of identification and that the promotion of this identification experience depends on the presence of a rationale that is communicated in an autonomy-supportive way.     

Evolutionary psychology and developmental dynamics: comment on Lickliter and Honeycutt (2003)

Evolutionary psychology provides a cogent metatheory for psychological science. It has furnished compelling theories of major domains of human functioning, including mating, parenting, kinship, morality, cooperation, conflict, aggression, and aesthetics. It has produced hundreds of empirical discoveries missed entirely by prior psychologists. Developmental dynamics, properly conceived, can add to the theoretical foundation of evolutionary psychology. But it has not provided alternative theories capable of explaining the many detailed empirical discoveries made by evolutionary' psychologists. Nor has it generated a comparable bounty of new empirical discoveries. By critical scientific standards--theoretical cogency, predictive accuracy, interdisciplinary consistency, and empirical harvest--modern evolutionary psychology fares well compared with alternatives.     

Toward an understanding of adult intellectual development: investigating within-individual convergence of interest and knowledge profiles

To further our understanding of the role interests play in the development of adult intellect, this study examines the relationship between intraindividual differences in interest and knowledge profiles. On the basis of a sample of 330,154 individuals, results show a moderate, positive average intraindividual correlation between interest and knowledge that increases as individuals age and is stronger for men than for women. Consistent with recent theories regarding the development of adult intelligence, expertise, and talent, these results demonstrate that noncognitive intraindividual differences can add to one's understanding of the acquisition of knowledge and skills. The current findings regarding the intraindividual convergence of interests and knowledge substantiate K. Murphy's (1998) call for renewed research on interests and point to the usefulness of an intraindividual perspective in applied psychology.
