Developmental and gender effects in the transmission of information about a tool-use task were investigated within a "diffusion chain" design. One hundred and twenty-seven children (65 three-year-olds and 62 five-year-olds) participated. Eighty children took part in diffusion chains in which consecutive children in chains of five witnessed two…

Eye movements across advertisements express a temporal pattern of bursts of respectively relatively short and long saccades, and this pattern is systematically influenced by activated scene perception goals. This was revealed by a continuous-time hidden Markov model applied to eye movements of 220 participants exposed to 17 ads under a…

Grammar has often found itself at the centre of innovations in English language teaching. In the last forty years the role of grammar has gone through three main stages: absolute prominence, exclusion, reintroduction with caution. These three stages have been associated respectively to three different approaches to instruction: "focus on forms",…

The present study adapted the "Blueprint of the Reader" in comprehending language by Perfetti [2000, C. M. Brown & P. Hagoort. (Eds.), "The neurocognition of language" (pp. 167-208). Oxford, UK: Oxford University Press] as a framework for understanding Chinese language and reading comprehension in a group of 361 secondary…

The purpose of this study was to expand the current literature on word definitions by focusing on definitions of idioms provided by several age groups. Preadolescents, young adolescents, older adolescents, and adults wrote definitions for 10 frequently used idioms and also rated their familiarity with the idiomatic expressions. Participants'…

Retrieval monitoring enhances episodic memory accuracy. For instance, false recognition is reduced when participants base their decisions on more distinctive recollections, a retrieval monitoring process called the distinctiveness heuristic. The experiments reported here tested the hypothesis that autobiographical elaboration during study (i.e.,…

Three hypotheses of forgetting from immediate memory were tested: time-based decay, decreasing temporal distinctiveness, and interference. The hypotheses were represented by 3 models of serial recall: the primacy model, the SIMPLE (scale-independent memory, perception, and learning) model, and the SOB (serial order in a box) model, respectively.…

Purpose: This study examined alterations in ventilation and speech characteristics as well as perceived dyspnea during submaximal aerobic exercise tasks. Method: Twelve healthy participants completed aerobic exercise-only and simultaneous speaking and aerobic exercise tasks at 50% and 75% of their maximum oxygen consumption (VO[subscript 2] max).…

We examined the ability to use static line drawings of eye gaze cues to orient visual-spatial attention in children with high functioning autism (HFA) compared to typically developing children (TD). The task was organized such that on "valid trials," gaze cues were directed toward the same spatial location as the appearance of an upcoming target,…

There is abundant evidence from behavioral and neurophysiological experiments for the distinction of natural versus artifactual categories and a gender-specific difference: women's performances in cognitive tasks increase when natural categories are used, whereas men's performances increase with artifactual categories. Here, we used the semantic…

The present study investigated whether the neural correlates of source memory vary according to study task. Subjects studied visually presented words in one of two background contexts. In each test, subjects made old/new recognition and source memory judgments. In one study test cycle, study words were subjected to animacy judgments, whereas in…

In previous work we reported robust collaborative learning for referential labels in patients with hippocampal amnesia, resulting in increasingly rapid and economical communication or "common ground" with their partners [Duff, M. C., Hengst, J., Tranel, D., & Cohen, N. J. (2006). "Development of shared information in communication despite…

We explored the effects of task-related factors on reasoning processes in geometry focusing on a comparison-of-perimeters task in which the irrelevant feature area interferes with the reasoning process. We studied the effects of congruity, salience, and complexity on participants' accuracy of responses and reaction times. The study shows that…

Performing and learning motor skills has been shown to be enhanced if the performer adopts an external relative to internal focus (or no focus) of attention (Wulf, 2007). The present study examined the generalizability of this effect to top-level performers (balance acrobats). Participants performed a balance task (standing on an inflated rubber…

This study examined the ability of children with Asperger Syndrome (AS) to attribute mental states to characters in a new computerised, advanced theory of mind measure: The Animated Theory of Mind Inventory for Children (ATOMIC). Results showed that children with AS matched on IQ, verbal comprehension, age and gender performed equivalently on…
