Sensorimotor difficulties are common in children with autism spectrum disorder, and it has been suggested that motor planning problems underlie their atypical movements. At early school-age, motor planning development typically involves changes in visuomotor integration, a function known to be affected in autism spectrum disorder. However, there…

As more entrepreneurial experiences are integrated into engineering programs, students are faced with new challenges they need help in managing. While previous research has identified entrepreneurial activities that engineering students struggle with, the antecedents of these difficulties have not been directly investigated. Drawing on an…

Creativity is a broad and complex construct, difficult to define and to quantify, assumed to introduce new impulses into science education (STEM), and leading to better acceptance of science by adolescents. Therefore, increasing efforts are being undertaken to integrate traditional creativity (Arts), in modifying STEM to STEAM. Consequently, a…

We examined whether attained socioeconomic status (SES) moderated genetic and environmental sources of individual differences in cognitive performance using pooled data from 9 adult twin studies. Prior work concerning SES moderation of cognitive performance has focused on rearing SES. The current adult sample of 12,196 individuals (aged 27-98…

Retrieval practice is known to lead to better retention of a to-be-learned material than restudy (i.e., the testing effect). However, few studies have investigated retrieval practice in relation to working memory capacity (WMC) and personality characteristics such as grittiness (Grit) and need for cognition (NFC). In two experiments, we examined…

Several judgment and decision-making tasks are assumed to involve memory functions, but significant knowledge gaps on the memory processes underlying these tasks remain. In a study on 568 adults between 25 and 80 years of age, hypotheses were tested on the specific relationships between individual differences in working memory, episodic memory,…

Background: In accordance with the social information processing model, how adolescents attribute cause to a particular social situation (e.g., bullying) they witness or participate in, influences their online social information processing, and hence, how they will act in the situation. Objective: The aim of the present study was to explore how…

This paper presents a comprehensive analysis of the link between age and proficiency in information-processing skills, based on information drawn from the Survey of Adult Skills (PIAAC). The data reveal significant age-related differences in proficiencies, strongly suggesting that proficiency tends to "naturally" decline with age. Age…

The study examined the extent to which time-related gains in cognitive performance, so-called Flynn effects, generalize across sub-factors of episodic memory (recall and recognition) and semantic memory (knowledge and fluency). We conducted time-sequential analyses of data drawn from the Betula prospective cohort study, involving four age-matched…

The purpose of this cross-national descriptive study is to measure the extent of children's sexual knowledge and sexual understanding at various ages and to identify what processes of thought children use in trying to explain biological functions and the phenomena of their own bodies as they grow and change. Sexual thinking is defined as thinking…

The conceptions of information needs of seven American and seven Swedish mechanics employed by a Swedish multinational machine industry are compared by using perspective text analysis to analyze their verbal responses to three open-ended questions concerning their need for work-related information. The structures embedded in the texts are…

A subtest of the Swedish Scholastic Aptitude Test dealing with interpretation of diagrams, tables, and maps (DTM) was studied to see whether the position or other characteristics of test items affected the noted gender differences in results. Results with 116,017 students show an effect of position on gender differences. (SLD)

It is suggested that a reader's idea structure will affect processing of incoming information. Two aspects of the idea structure are further developed--the truth value aspect and the analytic level aspect. The idea structure can be characterized by ideas consisting of propositions which are considered to be more or less true or false (beliefs), or…

In a sample of 92 children aged 6-13 years this study investigates the normal developmental change in the relation between executive functioning (EF) and the core behavioural symptoms associated with attention deficit hyperactivity disorder (ADHD) (hyperactivity/impulsivity and inattention) as well as symptoms often co-occurring with childhood…
