Phoneme awareness is critical for literacy acquisition in English, but relatively little is known about the early development of phonological awareness in ESL (English as a second language) bilinguals when their two languages have different phonological structures. Using parallel tasks in English and Mandarin, we tracked the development of L1…

We report 3 experiments that examined whether presentation of a spoken word creates an attentional bottleneck associated with lexical processing in the absence of a response to that word. A spoken word and a visual stimulus were presented in quick succession, but only the visual stimulus demanded a response. Response times to the visual stimulus…

Although functional cerebral asymmetries (FCAs) affect all cognitive domains, their modulation of the efficacy of specific executive functions is largely unexplored. In the present study, we used a lateralized version of the task switching paradigm to investigate the relevance of hemispheric asymmetries for cognitive control processes. Words were…

Driving on a busy road, eluding a group of predators, or playing a team sport involves keeping track of multiple moving objects. In typical laboratory tasks, the number of visual targets that humans can track is about four. Three types of theories have been advanced to explain this limit. The fixed-limit theory posits a set number of attentional…

We examined how general intelligence, personality, and emotional intelligence--measured as an ability using the MSCEIT--predicted performance on a selective-attention task requiring participants to ignore distracting emotion information. We used a visual prime in which participants saw a pair of faces depicting emotions; their task was to focus on…

In the present study, speeded tasks with differing assumed difficulties of the trials are regarded as a special class of simple cognitive tasks. Exploratory latent growth modeling with data-driven shape of a growth curve and nonlinear structured latent curve modeling with predetermined monotonically increasing functions were used to analyze…

There is considerable debate about whether differential delay eyeblink conditioning can be acquired without awareness of the stimulus contingencies. Previous investigations of the relationship between differential-delay eyeblink conditioning and awareness of the stimulus contingencies have assessed awareness after the conditioning session was…

Abstract concepts are traditionally thought to differ from concrete concepts by their lack of perceptual information, which causes them to be processed more slowly and less accurately than perceptually-based concrete concepts. In two studies, we examined this assumption by comparing concreteness and imageability ratings to a set of perceptual…

This study examines the impact of macro-context factors on the behavior of school principals. More specifically, the article illuminates how a nation's level of economic development, societal culture, and educational system influence the amount of time principals devote to their job role and shape their allocation of time to instructional…

Computer-assisted experiments with CdS and CdSe photoresistors are described. The most important characteristics of the photoresistors are determined: (i) the spectral response, (ii) the photocurrent versus incident radiant power, (iii) the rise and decay time constants and (iv) the frequency response to modulated light. The photoconductivity gain…

In this article, Rosa Bruno-Jofre and Jon Igelmo Zaldivar examine Ivan Illich's own critique of "Deschooling Society", and his subsequent revised critique of educational institutions and understanding of education, within the context of both his personal intellectual journey and the general epistemological shift that started to take shape in the…

Students' self-determined or autonomous motivation in educational contexts is associated with adaptive educational and behavioural outcomes including persistence on educational tasks and academic performance. A key question for educators is whether promoting autonomous motivation toward activities in an educational context leads to increased…

The aims of the study were to analyze: (1) whether significant differences exist between children with typical development and children with developmental coordination disorders (DCD) in their preference to participate in leisure activities (2) whether the teacher estimation of activity form (TEAF) evaluation predicts participation preference.…

The study examined whether the modality effect is caused by either high visuo-spatial load or a lack of temporal contiguity when processing written text and pictures. Students (N = 147) viewed pictures on the development of tornados, which were accompanied by either spoken or written explanations presented simultaneously with, before, or after the…

Cognitive efficiency (CE) is generally defined as qualitative increases in knowledge gained in relation to the time and effort invested in knowledge acquisition. Across disciplines, limited consensus exists concerning the conceptual and measurement properties of CE partly because some researchers indiscriminately use the construct of CE to…
