Modern educational technology has the potential to support students to use their study time more effectively. Learning analytics can indicate relevant individual differences between learners, which adaptive learning systems can use to tailor the learning experience to individual learners. For fact learning, cognitive models of human memory are…

Recent years have seen a growing research interest in the notion of directed motivational currents (DMCs) that defines highly intense motivational surges oriented to a much-desired goal of personal significance. However, the learner characteristics that induce individual-level variability in DMCs have yet to be explored. In particular, the role of…

This study compares the performance of native speakers and adult second language (L2) learners on tasks tapping proficiency in grammar, vocabulary, and collocations. In addition, data were collected on several predictors of individual differences in linguistic attainment, including some related to language experience (print exposure, education,…

The major social science theories on adolescent risk-taking--strain, social control, and differential association theories--have received substantial empirical support. The relationships between variables central to these theories and individual differences in temperament related to risk-taking, however, have not been adequately studied. In a…

The current study examined the effects of text-based relational (i.e., cohesion), propositional-specific (i.e., lexical), and syntactic features in a source text on subsequent integration of the source text in spoken responses. It further investigated the effects of word integration on human ratings of speaking performance while taking into…

Objective: This study examined the relation of process variables to the outcome of group drug counseling, a commonly used community treatment, for cocaine dependence. Method: Videotaped group drug counseling sessions from 440 adult patients (23% female, 41% minority) were rated for member alliance, group cohesion, participation, self-disclosure,…

To investigate children's theories of motivation, we asked 166 children (8-12 years of age) to rate the effect of various motivational strategies on task interest, over the short and long terms, in activities described as appealing or unappealing. Children viewed the rewards strategy as resulting in greatest interest except when implemented over…

This article concerns individual differences in the associative meaning of psychological concepts. Associative meaning may be assessed with prototype methodology, which yields a list of features of the concept ordered according to their rated importance. Our theory concerns individual differences in a concept's associative meaning: A personal…

This study investigated differences between attributional style and student adaptation to college for students with and without disabilities. In terms of attributional style, the students with disabilities demonstrated a more internal, stable, and global attributional style for both positive events and negative events. In terms of student…

Results in this study suggest that it is possible to use performance on a moderator or predictability scale to select a subgroup for whom correspondence between two predictors and the criterion is much greater than that of a subgroup whose scores on the moderator indicate a lesser degree of correspondence.

This editorial proposes that the dependent variables that predict childhood intelligence quotient (IQ) from habituation and recognition memory assessments made during infancy may primarily reflect individual differences in rate of information processing. Inhibition may be a stable thread in mental development. (Author/SLD)

Deviations in children's mental test performance were studied for children of 169 disadvantaged mothers at 24, 48, and 96 months to determine whether aspects of the child rearing environment predicted the deviations from expected values. Relationships between aspects of the environment, child intelligence, and child characteristics are discussed.…

Reports a study that examined the influence of authoritarianism on the formation of behavioral intentions by female college students. High authoritarians took subjective norms less into account relative to low authoritarians, providing support for the theory that personal and subjective norms can be distinguished empirically. (LS)

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

The Rasch item analysis model is supposed to yield norm-free estimates of ability and easiness values, but there are several possible interpretations of the nature and extent of such norm-freeness. One such interpretation was that to involve the scores of one single experimental group of testees which were embedded in four differently skewed…
