Adaptive categorization in unsupervised learning.

In 3 experiments, the authors provide evidence for a distinct category-invention process in unsupervised (discovery) learning and set forth a method for observing and investigating that process. In the 1st 2 experiments, the sequencing of unlabeled ...

Multifocal slow potential generation revealed by high-resolution EEG and current density reconstruction.

In this work we used high-resolution EEG (123 channels) and current density reconstruction (CDR) to analyze the generators of slow potentials (SPs) in 31 healthy individuals. SPs were obtained during a task-performance feedback anticipation paradigm. The ...

Prediction of seizure-onset laterality by using Wada memory asymmetries in pediatric epilepsy surgery candidates.

PURPOSE: Because the capacity of intracarotid amobarbital (Wada) memory assessment to predict seizure-onset laterality in children has not been thoroughly investigated, three comprehensive epilepsy surgery centers pooled their data and examined Wada ...

Sodium methohexital (brevital) as an anesthetic in the Wada test.

PURPOSES: We report our experience with sodium methohexital (Brevital) as an anesthetic used in the Wada test for language and memory in 86 epilepsy surgery patients (173 procedures). METHODS: The methods are compared with those of the more commonly used ...

Two routes to remembering (and another to remembering not).

In this article, the author presents evidence about 2 mechanisms of remembering that occur when target stimuli are presented in meaningful contexts. One occurs when the context has been seen previously; the other occurs when the context is new in the ...

Toward a unified account of spacing effects in explicit cued-memory tasks.

Memory for repeated items improves when presentations are spaced during study. This effect is found in memory tasks using different types of material, paradigms, and participant populations. Although several explanations have been proposed, none explains ...

Retrograde enhancement of kinesthetic memory by alcohol and by glucose.

Several studies have reported that administration of a low dose of alcohol is capable of retrograde enhancement of memory. It has been postulated that the neurobiological mechanisms underlying this effect may involve the liberation of glucose and/or ...

Sentence context, word recognition, and repetition blindness.

When the sentence She ran her best time yet in the rice last week is displayed using rapid serial visual presentation, viewers sometimes misread rice as race (M. C. Potter, A. Moryadas, I. Abrams, & A. Noel, 1993). Seven experiments combined misreading ...

Consistency in childrens reports of sexual and physical abuse.

OBJECTIVE: The goal of the present study was to investigate the consistency of childrens reports of sexual and physical abuse. METHOD: A group of 222 children, ages 3-16 years, participated. As part of legal investigations, the children were interviewed ...

Covert operations: orthographic recoding as a basis for repetition priming in word identification.

When a word is generated from a semantic cue, coincident orthographic visualization of that word may cause priming on a subsequent perceptual identification test. A task was introduced that required subjects to visualize the orthographic pattern of ...
