Individual differences in psychophysiological function have been shown to influence the balance between flexibility and distractibility during attentional set-shifting [e.g., Dreisbach et al. (2005). Dopamine and cognitive control: The influence of spontaneous eyeblink rate and dopamine gene polymorphisms on perseveration and distractibility.…

This paper explores conceptions of the purpose of fieldwork held by undergraduates and academic staff in the disciplines of geography and geology. Phenomenographic analysis of written data reveals six qualitatively distinct conceptions broadly classified as "fragmented" and "cohesive". While considerable commonality in…

Individual differences in mathematics performance may stem from domain-general factors like working memory and intelligence. Parietal and frontal brain areas have been implicated in number processing, but the influence of such cognitive factors on brain activity during mathematics processing is not known. The relationship between brain mechanisms…

During childhood and adolescence, ongoing white matter maturation in the fronto-parietal cortices and connecting fiber tracts is measurable with diffusion-weighted imaging. Important questions remain, however, about the links between these changes and developing cognitive functions. Spatial working memory (SWM) performance improves significantly…

Two child groups (5-6 and 8-9 years of age) participated in a challenging rule-following task while they were (a) told that they were in the presence of a watchful invisible person ("Princess Alice"), (b) observed by a real adult, or (c) unsupervised. Children were covertly videotaped performing the task in the experimenter's absence. Older…

This study examines the beginning of the conceptual understanding of the first number-words and what role language can play in developing the notion of numbers. To that end, 2 1/2- and 3 1/2-year-old Basque and Spanish monolingual children's (N = 131) basic numeracy skills are analysed by means of two different experimental procedures: "Give-N"…

The objective of this study is to analyze the relationship between preservice teachers' time and study environment management, effort regulation, self-efficacy beliefs, control of learning beliefs and metacognitive self-regulation. This study also investigates the direct and indirect effects of metacognitive self-regulation on time and study…

Executive function (EF) skills are the attention-regulation skills that make it possible to sustain attention, keep goals and information in mind, refrain from responding immediately, resist distraction, tolerate frustration, consider the consequences of different behaviors, reflect on past experiences, and plan for the future. As EF research…

South African organisations and particularly institutions of higher learning have been confronted with workforces that increasingly reflect the diversity of the South African population. This changing workforce composition implies that the multitude of individual and cultural differences and similarities become increasingly apparent among…

This study compared job stress levels of Texas agricultural science cooperating teachers and Texas agricultural science student teachers across a semester. The research objectives included describing secondary agricultural science cooperating teachers and student teachers perceptions of stressors, by time of semester (beginning, middle, and end),…

In many public primary schools across different countries, generalist primary teachers are required to teach all subjects, including music, dance, drama and visual arts. This study investigates the background and confidence of preservice primary teachers from five countries in relation to drama and drama education. It also examines if there is a…

Although phonemic awareness is a known predictor of early decoding and word recognition, less is known about relationships between phonemic awareness and text reading fluency. This longitudinal study is the first to investigate this relationship by measuring eye movements during picture matching tasks and during silent sentence reading. Time spent…

Although autobiographical memory specificity is an important developmental feature fostering adaptation throughout life, little is known about factors related to interindividual differences in autobiographical memory specificity. The current study investigated associations with early adolescents' communication with mother about their experiences…

This first Japanese twin study of early literacy development investigated the extent to which genetic and environmental factors influence individual differences in prereading skills in 238 pairs of twins at 42 months of age. Twin pairs were individually tested on measures of phonological awareness, "kana" letter name/sound knowledge,…

Utilizing latent transition analysis and multidimensional scaling growth analysis, the authors studied the emerging developmental trajectories in word literacy (i.e., word-reading competence) of a group of 1,503 kindergarteners. Specifically, 3 hypotheses with respect to growth patterns in word literacy from kindergarten to Grade 2 were examined:…
