In the present study we examined the processing demands of three reading comprehension tests, namely the Woodcock-Johnson Passage Comprehension (WJPC), a Curriculum-Based Measure test (CBM-Maze), and a Recall test, in the early elementary years. Our investigation was theoretically motivated by Perfetti's Verbal Efficiency Theory and examined the…

This study examined whether the observed effectiveness of recasts is influenced by the type of outcome measure used and whether different aspects of working memory are differentially associated with learners' performance on the various outcome measures. The participants were 90 learners of English as a foreign language, who were randomly assigned…

This study of infant declarative memory concurrently examined brain-electrical activity and deferred imitation performance in 10-month-old infants. Continuous electroencephalogram (EEG) measures were collected throughout the activity-matched baseline, encoding (modeling) and retrieval (delayed test) phases of a within-subjects deferred imitation…

The dynamics of human memory are complex and often unintuitive, but certain features--such as the fact that studying results in learning--seem like common knowledge. In 12 experiments, however, participants who were told they would be allowed to study a list of word pairs between 1 and 4 times and then take a cued-recall test predicted little or…

Gene expression is a key process for memory consolidation. Recently, the participation of epigenetic mechanisms like histone acetylation was evidenced in long-term memories. However, until now the training strength required and the persistence of the chromatin acetylation recruited are not well characterized. Here we studied whether histone…

After acquisition, memories associated with contextual fear conditioning pass through a labile phase, in which they are vulnerable to hippocampal lesions, to a more stable state, via consolidation, in which they engage extrahippocampal structures and are resistant to such disruption. The process is accompanied by changes in the form of the memory…

The institutional machine of contemporary activity theory currently appears to be constrained by centring on the structure of mediated activity first voiced by Vygotsky. As a centring, such a principle, it is argued, continually restores the equilibrium of the institutional machine in alignment with its possible development in the polysemy of…

In the present study, we explored why interspersing quantitative details through a multimedia lesson detracts from learners' qualitative understanding. Three experimental conditions were created. In each, participants had to study a qualitative text on the formation, propagation, and dispersion of ocean waves. In the concise condition no…

Educators are barraged with information about the value of brain food, water, exercise, and vitamins on student learning. This information is often contradictory to and not substantiated by medical or cognitive research. As a neurologist and middle school teacher, the author has found the evidence supporting the value of these factors limited,…

A developmental association exists between colour preference and emerging colour term acquisition in young children. Colour preference might influence colour term acquisition by directing attention towards or away from a particular colour, making it more or less memorable. To investigate the role that colour preference may have in the acquisition…

The relationship between nonword repetition ability and vocabulary size and vocabulary learning has been a topic of intense research interest and investigation over the last two decades, following the demonstration that nonword repetition accuracy is predictive of vocabulary size (Gathercole & Baddeley, 1989). However, the nature of this…

Limits to the capacity of visual short-term memory (VSTM) indicate a maximum storage of only 3 or 4 items. Recently, it has been suggested that activity in a specific part of the brain, the posterior parietal cortex (PPC), is correlated with behavioral estimates of VSTM capacity and might reflect a capacity-limited store. In three experiments that…

Nairne, Thompson, and Pandeirada (2007) reported a series of experiments in which processing unrelated words in terms of their relevance to a grasslands survival scenario led to better retention relative to other semantic processing tasks. The impetus for their study was the premise that human memory systems evolved under the selection pressures…

The generation manipulation has been critical in delineating differences between implicit and explicit memory. In contrast to past research, the present experiments indicate that generating from a rhyme cue produces as much perceptual priming as does reading. This is demonstrated for 3 visual priming tasks: perceptual identification, word-fragment…

Two diverging hypotheses concerning the influence of surprising events on hindsight effects have been proposed: Although some authors believe that surprising events lead to a reversal of hindsight bias, others have proposed that surprise increases hindsight bias. Drawing on the separate-components view of the hindsight bias (which argues that…
