Does the perception of moving eyes trigger reflexive visual orienting in autism?

Does movement of the eyes in one or another direction function as an automatic attentional cue to a location of interest? Two experiments explored the directional movement of the eyes in a full face for speed of detection of an aftercoming location ...

The development of a word-learning strategy.

Two studies investigated young infants use of the word-learning principle Mutual Exclusivity. In Experiment 1, a linear relationship between age and performance was discovered. Seventeen-month-old infants successfully used Mutual Exclusivity to map novel ...

Dynamics of visual feedback in a laboratory simulation of a penalty kick.

Sport scientists have devoted relatively little attention to soccer penalty kicks, despite their decisive role in important competitions such as the World Cup. Two possible kicker strategies have been described: ignoring the goalkeeper action (open loop) ...

Top-down control over biased competition during covert spatial orienting.

Larger benefits of spatial attention are observed when distractor interference is prevalent, supporting the view that spatial selection facilitates visual processing by suppressing distractor interference. The present work shows that cuing effects with ...

Form-from-motion: MEG evidence for time course and processing sequence.

The neural mechanisms and role of attention in the processing of visual form defined by luminance or motion cues were studied using magnetoencephalography. Subjects viewed bilateral stimuli composed of moving random dots and were instructed to covertly ...

Normative data and naming times for action pictures.

The present article provides Spanish norms for name agreement, printed word frequency, word compound frequency, familiarity, imageability, visual complexity, age of acquisition, and word length (measured by syllables and phonemes) for 100 line drawings ...

Spatiotemporal activation of the two visual pathways in form discrimination and spatial location: a brain mapping study.

To address the question of the relationship between the two visual pathways, a ventral stream for object and form vision and a dorsal stream for spatial and motion vision, we measured the spatiotemporal activation patterns in the two pathways responding ...

A framework for consciousness.

Here we summarize our present approach to the problem of consciousness. After an introduction outlining our general strategy, we describe what is meant by the term framework and set it out under ten headings. This framework offers a coherent scheme for ...

Signal strength determines the nature of the relationship between perception and working memory.

Neurophysiological and behavioral studies have shown that perception and memory share neural substrates and functional properties. But are perception and the active working memory of a stimulus one and the same? To address this question in the spatial ...

When the target becomes the mask: using apparent motion to isolate the object-level component of object substitution masking.

J. T. Enns and V. Di Lollo (1997) discovered a new form of visual masking that they labeled object substitution masking (OSM). OSM occurs when 4 dots, presented around a target, trail in the display after target offset. The present study showed that the ...
