Regional cerebral blood flow changes during visually induced subjective sadness in healthy elderly persons.

This study examined regional cerebral blood flow (rCBF) changes associated with visually induced sad affect in healthy elderly persons. Subjects viewed sadness-laden, happiness-laden, and emotionally neutral image sets while rCBF was recorded using ...

Recombinative generalization of within-syllable units in nonreading adults with mental retardation.

Two adults with mental retardation demonstrated the recombination of within-syllable units (onsets and rimes) using a spoken-to-printed-word matching-to-sample (MTS) procedure. Further testing with 1 participant showed comprehension of the printed words. ...

Age-related changes in brain responses to personally known faces: an event-related potential (ERP) study in humans.

Midlife period has not been investigated so far regarding associations between brain responses and spared abilities for face processing. This study examines the effects of midlife aging on behavioural performance and event-related potentials (ERPs) ...

An integrated network for invariant visual detection and recognition.

We describe an architecture for invariant visual detection and recognition. Learning is performed in a single central module. The architecture makes use of a replica module consisting of copies of retinotopic layers of local features, with a particular ...

Spatiotemporal characteristics of dynamic feature binding in visual working memory.

It has been proposed that visual working memory can hold a set of four to five coherent object representations. As a test of this proposal, I devised a paradigm called multiple object permanence tracking (MOPT) that measures memory for feature-location ...

Sampling efficiency and internal noise for motion detection, discrimination, and summation.

By comparing real observers to an ideal observer, previous studies have found that the detection of static patterns is limited by internal noise and by imperfect sampling efficiency. We developed and applied ideal observer models for the detection, ...

Grouping local directional signals into moving contours.

We consider how local motion signals are combined to represent the movements of spatially extensive objects. A series of band-pass target dots, whose collective motion defined a moving contour, was positioned within a field of randomly moving noise dots. ...

Response-monitoring dysfunction in aging and Alzheimers disease: an event-related potential study.

Executive control is a broad-reaching function that includes response monitoring and is likely implemented in the frontal lobes. Age- and dementia-related changes in response-monitoring were assessed during a Picture-Name Verification Task, using ...

Frontal lobe networks for effective processing of ambiguously expressed emotions in humans.

This study examines the neural substrates involved in the recognition of ambiguous facial expressions using functional magnetic resonance imaging. Subjects performed two tasks, one in which they judged facial expressions and another in which they ...

Acquiring an understanding of design: evidence from childrens insight problem solving.

The human ability to make tools and use them to solve problems may not be zoologically unique, but it is certainly extraordinary. Yet little is known about the conceptual machinery that makes humans so competent at making and using tools. Do adults and ...
