To examine the neurobiological consequences of early institutionalization, the authors recorded event-related potentials (ERPs) from 3 groups of Romanian children--currently institutionalized, previously institutionalized but randomly assigned to foster care, and family-reared children--in response to pictures of happy, angry, fearful, and sad…

This ethnographic research investigates how adolescents use writing. Deborah M. Alvarez uncovers the hidden abuses and violence that adolescents bore with each school day. In two different research sites, the author follows adolescents through their academic and personal lives to discover how they use writing only to uncover the impact the public…

"Harvard Education Letter" is published bimonthly at the Harvard Graduate School of Education. This issue of "Harvard Education Letter" contains the following articles: (1) Unleashing the "Brain Power" of Groups in the Classroom: The Neuroscience behind Collaborative Work (Nancy Walser); (2) Putting AP to the Test: New Research Assesses the…

When you hear students say that what they learn in school doesn't have much to do with life, or that getting the answer right is the most important thing, or that learning is only about getting good grades, what they're doing is reflecting a general set of expectations that are reinforced by schools themselves. Here's a book that boldly contends…

Decorah, Iowa (pop. 8,172 in 2000), is, in many ways, a typical small Midwestern community facing many of the same issues as most other areas such as a brain drain and a continuing struggle to find ways to stimulate the local economy. Perhaps the strengths and successes of the approaches used in Decorah can be attributed to its ability to identify…

Adolescence is a time of increased divergence between males and females in physical characteristics, behavior, and risk for psychopathology. Here we will review data regarding sex differences in brain structure and function during this period of the lifespan. The most consistent sex difference in brain morphometry is the 9-12% larger brain size…

Objective: Child and adolescent psychiatry is rife with examples of the sustained effects of early experience on brain function. The study of behavioral genetics provides evidence for a relation between genomic variation and personality and with the risk for psychopathology. A pressing challenge is that of "conceptually" integrating findings from…

Objective: Basal ganglia abnormalities have been suggested as contributing to motor, social, and communicative impairments in autism spectrum disorder (ASD). Volumetric analyses offer limited ability to detect localized differences in basal ganglia structure. Our objective was to investigate basal ganglia shape abnormalities and their association…

There's something wrong when attending a really good workshop leaves one sad. In mid-October, 80 dedicated, bright teachers and administrators met with some workshop leaders and speakers in Vermont to explore the growing difficulties that students with "executive function" problems have in school--problems that affect such things as…

Words denoting manipulable objects activate sensorimotor brain areas, likely reflecting action experience with the denoted objects. In particular, these sensorimotor lexical representations have been found to reflect the way in which an object is used. In the current paper we present data from two experiments (one behavioral and one neuroimaging)…

Semantic deficits in Alzheimer's disease have been widely documented, but little is known about the integrity of semantic memory in the prodromal stage of the illness. The aims of the present study were to: (i) investigate naming abilities and semantic memory in amnestic mild cognitive impairment (aMCI), early Alzheimer's disease (AD) compared to…

Decision-making involves the ability to choose between competing actions that are associated with uncertain benefits and penalties. The Iowa Gambling Task (IGT), which mimics real-life decision-making, involves learning a reward-punishment rule over multiple trials. Patients with damage to ventromedial prefrontal cortex (VMPFC) show deficits…

Norepinephrine receptors have been studied in emotion, memory, and attention. However, the role of alpha1-adrenergic receptors in fear conditioning, a major model of emotional learning, is poorly understood. We examined the effect of terazosin, an alpha1-adrenergic receptor antagonist, on cued fear conditioning. Systemic or intra-lateral amygdala…

Although the relationship between stress intensity and memory function is generally believed to follow an inverted-U-shaped curve, strikingly this phenomenon has not been demonstrated under the same experimental conditions. We investigated this phenomenon for rats' performance in a hippocampus-dependent learning task, the radial arm water maze…

This study evaluated the psychometric properties of a simple scale for measuring positive interpersonal attitudes of depressed stroke patients, with regard to their cognitive limitations. Two versions of the Attitudes Towards Relationships Scale were developed and administered to depressed stroke (n = 48) and control rheumatic/orthopaedic (n = 45)…
