The purpose of the present study was to test the efficacy of a visuospatial working memory (WM) training in terms of its transfer effects and maintenance effects, in the young-old and old-old. Forty young-old and 40 old-old adults took part in the study. Twenty participants in each age group received training with a visuospatial WM task, whereas…

This article discusses the role of assessment in a response-to-intervention model. Although assessment represents only 1 component in a response-to-intervention model, a well-articulated assessment system is critical in providing teachers with reliable data that are easily interpreted and used to make instructional decisions. Three components of…

In this article, the author reflects on findings from research on the role and impact of teaching assistants and experience of working as a special educational needs (SEN) officer. Research evidence suggests the reliance on teaching assistants to include pupils with Statements of SEN in mainstream settings masks a collective, though unintentional,…

This article considers the impact of the increasing use of the visual mode in texts found in urban landscapes on two 3-year-olds' understanding of communication practices. The data discussed are taken from a study into a group of 3- to 6-year-olds' interaction with and emerging comprehension of the visual mode and its connection to writing in…

This study examined the effect of short-term high-variability phonetic training on the perception of English /b/, /v/, /d/, /ð/, /ae/, /? /, /i/, and /i/ by Catalan/Spanish bilinguals learning English as a foreign language. Sixteen English-major undergraduates were tested before and after undergoing a four-session perceptual training program…

Three experiments investigate psychological, methodological, and domain-specific characteristics of loudness change in response to sounds that continuously increase in intensity (up-ramps), relative to sounds that decrease (down-ramps). Timbre (vowel, violin), layer (monotone, chord), and duration (1.8 s, 3.6 s) were manipulated in Experiment 1.…

Musical melodies are recognized on the basis of pitch and temporal relations between consecutive tones. Although some previous evidence (e.g., Saffran & Griepentrog, 2001) points to an absolute-to-relative developmental shift in listeners' perception of pitch, other evidence (e.g., Plantinga & Trainor, 2005; Schellenberg & Trehub,…

Five experiments demonstrate that when dots appear beside a briefly presented target object, and persist on view longer than the target, the flanked object is perceptually altered by the dots. Three methods are used to explore this "object trimming effect". Experiments 1-3 assess participants' conscious reports of trimmed digits, Experiment 4 uses…

Studies in rats and non-human primates suggest that medial temporal lobe (MTL) structures play a role in perceptual processing, with the hippocampus necessary for spatial discrimination, and the perirhinal cortex for object discrimination. Until recently, there was little convergent evidence for analogous functional specialisation in humans, or…

A well-documented experience of students of elementary Euclidean geometry is "seeing" a geometric result and being sure about its truth; this sort of experience gives rise to the notion of geometrical visualisation that is developed here. In this essay a philosophical argument for the epistemic potential of geometrical visualisation is reviewed,…

Central nervous networks, be they a part of the human brain or a group of neurons in a snail, may be designed to produce distinct patterns of movement. Central pattern generators can account for the development and production of normal vocal signals without auditory feedback in non-songbirds. Songbirds need auditory feedback to develop and…

We employ a single-trial correlational MEG analysis technique to investigate early processing in the visual recognition of morphologically complex words. Three classes of affixed words were presented in a lexical decision task: free stems (e.g., taxable), bound roots (e.g., tolerable), and unique root words (e.g., vulnerable, the root of which…

The present study explored the perceptual process of integration of luminance information in the production of the gray color of an object placed in an environment viewed from a window. The mean luminance of the object was varied for each mean luminance of the environment. Participants matched the gray color of the object with that of Munsell…

Skottun and Skoyles (2009) recently presented a comment on Vernier acuity and magnocellular dysfunctions in fragile X premutation carriers (Keri & Benedek, 2009). The authors concluded that our finding that the magnocellular deficit, as revealed by luminance-contrast sensitivity measurements, is associated with impaired Vernier acuity for…

People can appear inconsistent in their intuitions about sequences of repeated events. Sometimes people believe such sequences will continue (the "hot hand"), and sometimes people believe they will reverse (the "gambler's fallacy"). These contradictory intuitions can be partly explained by considering the perceived intentionality of the agent…
