A dual-process account of the development of scientific reasoning: The nature and development of metacognitive intercession skills

Metacognitive knowledge of the dual-processing basis of judgment is critical to resolving conflict between analytic and experiential processing responses [Klaczynski, P. A. (2004). A dual-process model of adolescent development: Implications for decision making, reasoning, and identity. In R. V. Kail (Ed.), Advances in child development and behavior, Vol. 31 (pp. 73–123). San Diego, CA: Academic Press]. Such conflict is ubiquitous when reasoning scientifically. Three studies explored the nature, development, and stability of this metacognitive knowledge. In each study, participants completed the ratio-bias judgment task, which assessed their tendency to make analytically based responses, and the ratio-bias evaluation task, which assessed their metacognitive knowledge of the processing basis of judgments on the task (Metacognitive Status). In Study 1, college students’ judgment performance was related to metacognitive status but not to general cognitive ability. In Study 2, metacognitive status was related to age and mathematics-related changes. Metacognitive status again predicted participants’ tendency to make analytically based judgments. In Study 3, college students’ judgments, but not metacognitive status, were affected by task conditions. The evidence suggests that assessing metacognitive knowledge is important for understanding how conflict between analytically and experientially based judgments is resolved.     

Predicting attendance at peer-assisted study sessions for statistics: role identity and the theory of planned behavior

Using a prospective study of 77 1st-year psychology students' voluntary attendance at peer-assisted study sessions for statistics, the authors tested the addition of role identity to the theory of planned behavior. The authors used a revised set of role-identity items to capture the personal and social aspects of role identity within a specific behavioral context. At the commencement of the semester, the authors assessed the students' attitudes, subjective norm, perceived behavioral control, role identity, and intention. The authors examined the students' class attendance records 3 months later. Attitudes and perceived behavioral control predicted intention, with intention as the sole predictor of attendance. Role identity also predicted intention, reflecting the importance of the student role identity in influencing decision making related to supplementary academic activities.

Attentional Limitations in Doing Two Tasks at Once

ABSTRACT— People generally have difficulty doing two tasks at once. To explain this fact, theorists have proposed that central processing—the thought-like stages following perceptual encoding and preceding response processing—takes place for only one task at a time. Because this bottleneck imposes severe limits on human cognitive processes, research has attempted to find exceptions. There is now solid evidence that, at least in the laboratory, the entire bottleneck can be completely bypassed under favorable combinations of circumstances. While these findings provide a ray of hope for enabling parallel multitasking in real-world scenarios, it will not be easy to take advantage of the combination of conditions that appear to be necessary.     

Predicting treatment response for childhood attention-deficit/hyperactivity disorder: Introduction of a heuristic model to guide research

Efficacious treatments for childhood attention-deficit/hyperactivity disorder (ADHD) have been clearly documented in the extant literature. However, significant challenges remain in delivering these treatments to the children and families they were developed to benefit. With the aim of better understanding the obstacles that impede delivery of treatments for ADHD, this paper reviews what is known regarding predictors of treatment acceptance, adherence, and success among families of children with ADHD. We identify several gaps in this literature, including the need for a strong, theoretically-driven model that encompasses parental cognitive variables in understanding the treatment experiences of these families.
