To investigate whether concurrent nonverbal sound sequences would affect visual-hemifield lexical processing, lexical-decision performance of 24 strongly right-handed students (12 men, 12 women) was measured in three conditions: baseline, concurrent neutral sound sequence, and concurrent emotional sound sequence. With the neutral sequence,…

We report the case of an immigrant who suffered from death threats and head trauma while a prisoner of war in Kuwait. Two months later, he began to hear conversations that had taken place previously. These perceptions occurred spontaneously or were induced by the patient's effortful concentration. The single photon emission computerized tomography…

Eighteen healthy young adults underwent event-related (ER) functional magnetic resonance imaging (fMRI) of the brain while performing a visual category learning task. The specific category learning task required subjects to extract the rules that guide classification of quasi-random patterns of dots into categories. Following each classification…

In this paper we present a case of "word-meaning deafness," characterised by serious problems in the comprehension of spoken language, whilst repetition and writing words and non-words from dictation are preserved. This performance indicates the impossibility of correctly accessing phonological representation from the semantic representation of…

Although deficits in confrontation naming are a common consequence of damage to the language areas of the left cerebral hemisphere, some patients with aphasia show relatively good naming ability. We measured effects of repeated practice on naming latencies for a set of pictured objects by three aphasic patients with near-normal naming ability and…

Hearing causes brain cells (neurons) to connect and neural networks to form. Advanced brain-scan technology and neuroscience research reveal that when children participate in music, the brain "light[s] up like a Christmas tree" in many different areas (Parr, Radford, & Snyder 1998, cited in Isenberg & Jalongo 2001, 159). The growing neural…

Lately, many studies have suggested that communication impairments in brain-damaged individuals might be explained--at least in part--in terms of cognitive resource allocation. Reproducing a clinical pattern in normal subjects by using a dual-task treatment might be a way of evaluating the role of cognitive resources in the right hemisphere's…

Two patients with medial frontal lobe damage involving the anterior cingulate cortex (ACC) performed a range of cognitive tasks, including tests of executive function and anterior attention. Both patients lesions extended beyond the ACC, therefore caution needs to be exerted in ascribing observed deficits to the ACC alone. Patient performance was…

Functional magnetic resonance imaging (fMRI) and event-related potential (ERP) experiments were conducted in the same group of subjects and with an identical task paradigm to investigate a possible relationship between hemodynamic and electrophysiological responses within the brain. The subjects were instructed to judge whether visually presented…

In this article, I respond to comments made by K. Salzinger and A. Aleman and A. S. David on my original article. The constructive, reconstructive, and interpretive nature of human cognition is well illustrated by these two responses to my recent article on schizophrenia. In the original article, I used meta-analytic summaries of the published…

Sensory or input factors can influence the strength of interference in the classic Stroop color-word task. Specifically, in a single-trial computerized version of the Stroop task, when color-word pairs were incongruent, opponent color pairs (e.g., the word BLUE in yellow) showed reduced Stroop interference compared with nonopponent color pairs…

Students who have sustained a traumatic brain injury (TBI) return to the school setting with a range of cognitive, psychosocial, and physical deficits that can significantly affect their academic functioning. Successful educational reintegration for students with TBI requires careful assessment of each child's unique needs and abilities and the…

This article reports the outcomes from 2 focus groups conducted to ascertain professional educators' perceptions regarding their (a) level of preparedness for working with students with traumatic brain injury (TBI), (b) ideas regarding ways to improve support to students and families, and (c) concerns about meeting the diverse needs of children…

In this paper an overview of research on the multilingual lexicon is presented as the basis for a model for processing multiple languages. With respect to specific issues relating to the processing of more than two languages, it is suggested that there is no need to develop a specific model for such multilingual processing, but at the same time we…

In working with right-brained or visual spatial children for the past 20 years, the author has noticed that they all learn in a similar manner. He has also noticed that a high percentage of gifted children are visual spatial learners. The more visual spatial a child is, the higher the potential for school difficulties. Since most teachers are…
