The role of own-body representations in action observation: a functional MRI study.
13 Jul 2009 
Does own-body information matter during the observation of another person? Using functional MRI, we sought to determine whether incompatibility between observed hand movements and the observer's hand posture leads to differential neural activation ...

Modulation of the motor area activity during observation of a competitive game.
13 Jul 2009 Watching competitive games is a pervasive entertainment in humans and likely to be facilitated by our social cognitive abilities. We investigated the brain activity during observation of a competitive game by using near-infrared spectroscopy. The ...

Is subjective duration a signature of coding efficiency?
10 Jul 2009 Perceived duration is conventionally assumed to correspond with objective duration, but a growing literature suggests a more complex picture. For example, repeated stimuli appear briefer in duration than a novel stimulus of equal physical duration. ...

Explicit eye movements failed to facilitate the precision of subsequent attentional localization.
9 Jul 2009 This study investigated the usefulness of explicit spatial coordinates from eye movements for the precision of covert shifts of attention within dense arrays of items. Observers shifted their attention covertly from one item to the next in response ...

Dissociable perceptual effects of visual adaptation.
8 Jul 2009 
Neurons in the visual cortex are responsive to the presentation of oriented and curved line segments, which are thought to act as primitives for the visual processing of shapes and objects. Prolonged adaptation to such stimuli gives rise to two ...

Stimulus duration influences perceived simultaneity in audiovisual temporal-order judgment.
8 Jul 2009 The temporal integration of stimuli in different sensory modalities plays a crucial role in multisensory processing. Previous studies using temporal-order judgments to determine the point of subjective simultaneity (PSS) with multisensory ...

Rubber hand illusion under delayed visual feedback.
7 Jul 2009 BACKGROUND: Rubber hand illusion (RHI) is a subject's illusion of the self-ownership of a rubber hand that was touched synchronously with their own hand. Although previous studies have confirmed that this illusion disappears when the rubber hand was ...

Momentary reductions of attention permit greater processing of irrelevant stimuli.
7 Jul 2009 Momentary reductions of attention can have extremely adverse outcomes, but it remains unclear whether increased distraction from irrelevant stimuli contributes to such outcomes. To investigate this hypothesis, we examined trial-by-trial ...

The contribution of mere recognition to the p300 effect in a concealed information test.
6 Jul 2009 In two experiments, we investigated the role of mere recognition in a P300 based CIT. Mere recognition was isolated by having participants respond based on an irrelevant dimension of the stimuli. In Experiment 1 stimuli consisted of familiar and ...

6 Jul 2009 Visual perception fluctuates across repeated presentations of the same near-threshold stimulus. These perceptual fluctuations have often been attributed to baseline shifts--i.e., ongoing modulations of neuronal activity in visual areas--driven by ...
