Neurological research has discovered much about how the brain works, Dr. Willis writes, but educators need to be cautious when applying this research to teaching. Following a brief explanation of the three most important technological advances in brain research (Positron Emission Tomography, Functional Magnetic Resonance Imaging, and Quantitative…

Lesioning studies are often used in cognitive neuroscience to make inferences about the architecture of cognition. Recently, computational models have been used to address some of the underlying assumptions-such as modularity and locality-often implicitly used when interpreting lesion data. In this article, we explore the ''functional…

Previous studies indicate that the benefits of dividing an information processing load across both cerebral hemispheres outweigh the costs of interhemispheric transfer as tasks become more difficult or cognitively complex. This is demonstrated as better performance when two stimuli to be compared are presented one to each visual field and…

Dissociation is typically defined as the lack of normal integration of thoughts, feelings, and experiences into consciousness and memory. The present article critically evaluates the research literature on cognitive processes in dissociation. The authors' review indicates that dissociation is characterized by subtle deficits in neuropsychological…

Although some theories suggest that anxious individuals selectively remember threatening stimuli, findings remain contradictory despite a considerable amount of research. A quantitative integration of 165 studies with 9,046 participants (clinical and nonclinical samples) examined whether a memory bias exists and which moderator variables influence…

Voluntary motor actions aim at and are thus governed by predictable action effects. Therefore, representations of an action's effects normally must become activated prior to the action itself. In 5 psychological refractory period experiments the authors investigated whether the activation of such effect representations coincides with the response…

This article aims to provide a theoretical framework to elucidate the neurophysiological underpinnings of deviance detection as reflected by mismatch negativity. A six-step model of the information processing necessary for deviance detection is proposed. In this model, predictive coding of learned regularities is realized by means of long-term…

Intuition usually is defined as the capability to act or decide appropriately without deliberately and consciously balancing alternatives, without following a certain rule or routine, and possibly without awareness (Gigerenzer, 2007; Hogarth, 2001; Klein, 2003; Myers, 2002). It allows action which is quick (e.g. reaction to a challenging…

Investigated role of response time on Wechsler Intelligence Scale for Children-Revised. For 131 children, total response time score for correct and incorrect performance was gleaned from each of Picture Arrangement, Block Design, and Object Assembly subtests. Examined utility of these response time measures in relation to other subtests. Discusses…

This study focused on the cognitive abstractness or concreteness of a subject, the level of cognitive complexity reflecting the ways in which a person receives, stores, and transmits information. (Author/RK)

Discusses the close interrelationships between the various cognitive functions of the brain and the possibility of improving memory through the use of mnemonic devices. Bibliography. (LC)

A critical review of the literature indicates that overselective attention: (1) is not limited to autistic children, (2) may be only one of several developmental lags these children display, and (3) may or may not be strongly correlated with children's language abilities and general intellectual abilities. (Author)

Argues that educational theory and practice are dominated by a language frame that structures thought and practice into an input-output form. Outlines an alternative view of reflection and recursion based on the conversation postulate. A conversation is a system of mutually interacting components. Each component "perturbs" other…
