Commonly proven abnormalities in the structure and functioning of the prefrontal cortex (PFC) are related to cognitive deficits in children with ADHD. The purpose of the randomized controlled study was to assess the efficacy of intervention using hemoencephalographic biofeedback (HEG BFB) in PFC in ADHD and neurotypical children. The final cohort…

The purpose of this study was to examine relationships among college students' 2 x 2 goal orientations (mastery-approach [MAp], mastery-avoidance [MAv], performance-approach [PAp], performance-avoidance [PAv]), situational motivation (intrinsic motivation, identified regulation, external regulation and amotivation) and effort/persistence in…

This study developed and tested a model to identify the predictors of retirement planning based on an extension of the theory of planned behavior ([TPB], Ajzen, 1991) that included individual differences in proactivity and time discounting. The results showed that personal attitudes, sense of control, social influence, and stable traits have a…

The purpose of this study was to determine the relationship between workplace learning and psychological variables, such as learning competency, motivation, curiosity, self-esteem and locus of control, and organizational variables, such as centralization of power, formality, merit system and communication. The studied population consisted entirely…

Data from 77 ninth-grade Spanish students who took an objective test, a performance assessment, and a measure of perceptions of control indicate that control perceptions predict scores on performance assessments, not objective tests. Performance assessments thus reflect motivational variables beyond the constructs being tested. (SK)

The development and validation of the Multidimensional-Multiattributional Causality Scales (MMCS) are described. The scales are distinctive because they measure locus of control specific to two goals--achievement and affiliation. Half of the items concern success, and half concern failure experiences. Results of four validity studies with under…

This paper develops and estimates a model of the educational process. Most researchers have relied on a single equation, educational production function, which is an unrealistic formulation. A pupil's achievement, motivation, expectations, self-concept, and his perceived parents' and teachers' expectations are determined jointly, not…

Two studies are described which capitalize on the strengths of the instructional development process for research purposes. Typically, developed courses have carefully-designed learning environment specifications, replicable instructional treatments, and well-proven achievement measures. A battery of questionnaires and rating scales concerning…
