This article examines an educational experiment with a unique combination of 3 elements: homework, the use of information and communication technology and a large degree of freedom of choice (student autonomy). More particularly, we study the effectiveness of a web-based intelligent tutoring system (ITS) that a school offers to its students as optional homework, in a sample of 355 first-year secondary students, using an experimental design. The results show that whether students make this noncompulsory homework in the web-based ITS is dependent on their prior achievement and their teacher, and if they practice, they tend to choose easier modules. Students thus do not seem to optimize learning gains, but rather balance their perceived value of practicing and their "expectancy," as found previously for regular (compulsory, non-ITS) homework. Regarding the value of choice, findings suggest that students may be poor judges of their most beneficial exercises pattern. Differentiation in ITS does not guarantee learning, unless scaffolding is tightly linked to it. In line with previous research, this research shows that practice does matter, though at varying intensities. Yet it also clarifies that motivation to make an effort is required, which adds to the lessons learned from homework research; both the perceived value and expectancy are at play and can be enhanced, for example, by teachers.

Highlights: [•] MLD is a heterogeneous disorder. [•] The seven number-specific processing skills are reducible to four factors. [•] Six clusters were found with unique patterns of cognitive strength and weaknesses. [•] The access deficit subtype is characterized by the weakest arithmetic performance. [•] None of the subtypes was particular to a specific age group or gender. [ABSTRACT FROM AUTHOR]

Highlights: [•] Kindergartener’s efficiency to process symbols is unique predictor of grade 1. [•] Efficiency to compare digits, to count and to estimate dots are predictors. [•] Are unique predictors above and beyond general cognitive and non-cognitive factors. [•] Dot comparison efficiency is not a unique predictor despite achievement level. [•] No task-specific effects were unique predictors of arithmetic. [ABSTRACT FROM AUTHOR]

Front-of-package (FOP) nutrition labels are placed on products to help consumers make healthy food choices. A lab-in-field experiment was conducted to test the effectiveness of two FOP labels in promoting healthy food choices among Dutch consumers, and to examine whether dieters and health conscious shoppers are more likely to use the FOP labels. In addition, it was examined whether the placement of relatively "good" FOP label scores on products might inadvertently lead to increases in serving sizes. Participants (N = 300) consisted of Dutch consumers shopping for groceries in a local supermarket. They were randomly assigned to one of three conditions (Nutri-score, Multiple Traffic Light (MTL) label, or no label control condition), presented with six different (labeled) cereals, and asked to make a choice. Next, participants were shown a product with a relatively good label score and selected their desired serving size. The results show that the Nutri-score promotes choice of the healthiest cereal. Dieting behaviour and health conscious shopping did not moderate this effect, and the labels did not affect serving size selection. Overall, the study provides evidence for the Nutri-score to promote healthy food choices among Dutch consumers. [ABSTRACT FROM AUTHOR]

Abstract: This comparative study explored whether psychogenic nonepileptic seizures (PNES) are a unique disorder with distinctive personality characteristics or (seen from the personality profile) PNES are allied with the domain of a general functional somatic symptom and syndrome (FSSS). We compared the Minnesota Multiphasic Personality Inventory 2 (MMPI-2) results for 41 patients with newly diagnosed PNES and 43 patients with newly diagnosed insomnia. There were no statistically significant quantitative scoring differences on the main clinical scales, indicating that there is no substantial difference in ”personality makeup” between the two groups with a FSSS. Additional subscale analysis indicated that patients with PNES reported significantly more somatic complaints (Hysteria 4) and bizarre sensory experiences (Schizophrenia 6). Further profile analysis revealed that the personality pattern of patients with PNES was characterized by a strong tendency toward ”conversion V, a lack of control pattern and less excessive worries” as compared with patients with insomnia. Patients with PNES are characterized by a stronger tendency toward somatization and externalization, which has treatment implications. [Copyright &y& Elsevier]
