Attempted to cross validate a model of relationships among social--contextual factors, individual differences, and intrinsic motivation in 219 adolescent students in required courses and elective courses. Results indicate data are best represented by a model that separates social-contextual factors, individual factors, intrinsic motivation, and…

Discusses the branching structure of hypermedia that can accommodate individual learning differences. Highlights include interactivity; self-learning skills; a conceptual framework; a model of self-regulated learning; prior knowledge; and future research directions. (Author/LRW)

This study evaluated Reiss's (2000) empirically derived system for understanding incompatibility of housemates in housing programs for people with mental retardation. Comparison of 57 dyads without significant conflict and 36 dyads with conflict found dissimilarity of basic motives and values was associated with housemate incompatibility as were…

Reviews evidence that children use diverse cognitive strategies; discusses the adaptive value of using diverse strategies; describes models of strategy choice based on rational calculations; and presents an overview of the distributions of associations model of children's strategy choice. (RH)

Utilizes the information processing model of human memory to provide teachers with suggestions for improving the teaching-learning process. Briefly explains and specifies applications of major theoretical concepts: attention, active learning, meaningfulness, organization, advanced organizers, memory aids, overlearning, automatically, and…

Reviews several lines of convergent research to discuss the relationship between developmental dyslexia and slow symbol naming speed. Describes the interactive development of orthographic and phonological codes, and methodological problems leading to underestimation of the importance of individual differences. Argues that an understanding of…

Dissimilar learners, although not candidates for special-education services, have difficulty adapting to the typical middle-school environment. The Intervention with Dissimilar Learners model adapts middle-school programs to meet student needs and achieve positive regard, teacher empowerment, and teacher as advisor objectives. The goal is building…

Two studies examined individual student differences (N=79) in student perceptions of learning context and studying utilizing a new statistical procedure (multidimensional unfolding analysis). The results confirm the existence of important associations between qualitatively different perceptions of learning context and individual approaches to…

Two studies involving 333 military recruits investigate individual differences in time-accuracy functions of inspection time (IT) in terms of psychological models. Two alternative interpretations of IT time-accuracy functions (processing-distraction and processing-speed, and pure processing-speed "cascade" models) are considered in…

Used weekly-obtained longitudinal observational data of infant crying, fretting/fussing, and smiling and the time spent in physical contact with mother to examine behavioral variability over a 15-month period. Found evidence of an important intraindividual variability between newborn and 5 months, and 5 and 10 months, but not between 10 and 15…

Suggests ways to use dynamic systems analysis to illuminate the pluralistic and multidimensional model described by Larivee, Normandeau, and Parent (2000). Issues discussed include the characteristics of developmental transitions, such as hysteresis; nature of growth processes, such as hierarchical development or predator-prey interactions; and…

Acknowledges that Halberstadt et al. have provided the field with a framework in which to organize ideas regarding affective social competence. Argues for modification of the model to stimulate thinking and further research, addressing points of modification in the areas of regulation as the core of the construct and self-factors influencing…

Institutions of higher education face exceptional challenges in today's environment. College costs are increasing, funding is decreasing and/or limited, public confidence is diminishing, the work-place is changing, and a shrinking pool of traditional-age college students exists. This creates an environment where colleges and universities find…

We evaluated the statistical power of single-indicator latent growth curve models (LGCMs) to detect correlated change between two variables (covariance of slopes) as a function of sample size, number of longitudinal measurement occasions, and reliability (measurement error variance). Power approximations following the method of Satorra and Saris…

In this article we describe the nature of attention deficit disorders (ADDs) within an individual differences model of abilities. In so doing, a model-based explanation for the sources of learning and performance difficulties among individuals identified with ADDs is provided. Earlier models of ADDs are discussed, and the proposed loci of ADDs…
