Cognitive performance and sleep quality in the elderly suffering from chronic insomnia. Relationship between objective and subjective measures.

OBJECTIVE: The objective of the present study was to evaluate the relationship between objective and subjective sleep quality and objective and subjective evaluation of cognitive performance in older adults suffering of chronic insomnia (using or not ...

Visual memory and motor planning in a natural task.

This paper investigates the temporal dependencies of natural vision by measuring eye and hand movements while subjects made a sandwich. The phenomenon of change blindness suggests these temporal dependencies might be limited. Our observations are largely ...

Change detection in an attended face depends on the expectation of the observer.

Sensitivity to a scene change during a brief interruption depends critically on a match between what the observer expects to see and the kind of change that occurs (Austen & Enns, 2000). The present study tested the generality of this conclusion using ...

Dissociable effects of dopaminergic therapy on spatial versus non-spatial working memory in Parkinsons disease.

There is now evidence for definite and early cognitive deficits in Parkinsons disease (PD), involving, in particular, executive functions and working memory. However, the distinction between visuo-spatial and non-spatial working memory deficits and the ...

Dissociable neural responses in the hippocampus to the retrieval of facial identity and emotion: an event-related fMRI study.

In studies with brain-damaged patients and experimental animals, the medial temporal lobe, including the hippocampus and parahippocampal gyrus, has been found to play a critical role in establishing declarative or episodic memory. We measured the neural ...

Comparison of computational models of familiarity discrimination in the perirhinal cortex.

This study compares the efficiency and plausibility of published computational models of familiarity discrimination in the perirhinal cortex. Substantial evidence indicates that the perirhinal cortex is involved in both the familiarity discrimination ...

Is it an animal? Is it a human face? Fast processing in upright and inverted natural scenes.

Object categorization can be extremely fast. But among all objects, human faces might hold a special status that could depend on a specialized module. Visual processing could thus be faster for faces than for any other kind of object. Moreover, because ...

Does disruption of a scene impair change detection?

When we view a scene, we generally feel that we have a rich representation of that scene. Recent research has shown, however, that we are unable to detect relatively large changes in scenes, which suggests an inability to retain the visual details from ...

Frontal and parietal participation in problem solving in the Tower of London: fMRI and computational modeling of planning and high-level perception.

This study triangulates executive planning and visuo-spatial reasoning in the context of the Tower of London (TOL) task by using a variety of methodological approaches. These approaches include functional magnetic resonance imaging (fMRI), functional ...

What you see is what you need.

We studied the role of attention and task demands for implicit change detection. Subjects engaged in an object sorting task performed in a virtual reality environment, where we changed the properties of an object while the subject was manipulating it. ...
