Effects of scene inversion on change detection of targets matched for visual salience.

This work examines how context may influence the detection of changes in flickering scenes. Each scene contained two changes that were matched for low-level visual salience. One of the changes was of high interest to the meaning of the scene, and the ...

Orienting of attention without awareness is affected by measurement-induced attentional control settings.

McCormick (1997) concluded that peripheral cues presented below a threshold of awareness could nevertheless attract attention because they facilitated target processing near the cue shortly after its presentation. Yet, whereas an exogenous shift of ...

Competition and selection during visual processing of natural scenes and objects.

When a visual scene, containing many discrete objects, is presented to our retinae, only a subset of these objects will be explicitly represented in visual awareness. The number of objects accessing short-term visual memory might be even smaller. ...

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. ...

Endogenous shifts of covert attention operate within multiple coordinate frames: evidence from a feature-priming task.

The locations of visual objects and events in the world are represented in a number of different coordinate frameworks. For example, a visual transient is known to attract (exogenous) attention and facilitate performance within an egocentric framework. ...

A comparison of the contrast effects in sound localization in the horizontal and vertical planes.

The effect of a background sound on the auditory localization of a single sound source was examined. Nine loudspeakers were arranged crosswise in the horizontal and the median vertical plane. They ranged from -20 degrees to +20 degrees, with the center ...

Information regarding structure and lightness based on phenomenal transparency influences the efficiency of visual search.

Phenomenal transparency reflects a process which makes it possible to recover the structure and lightness of overlapping objects from a fragmented image. This process was investigated by the visual-search paradigm. In three experiments, observers ...

Neither here nor there: localizing conflicting visual attributes.

Natural visual scenes are a rich source of information. Objects often carry luminance, colour, motion, depth and textural cues, each of which can serve to aid detection and localization of the object within a scene. Contemporary neuroscience presumes a ...

Does the cerebellum contribute to specific aspects of attention?

We present data on attentional and neuropsychological functions of 16 patients with focal cerebellar lesions (13 tumours, 3 haematomas) compared to normative test data, and to 11 control subjects matched for age, gender, and years of education. Patients ...

Scene content selected by active vision.

The primate visual system actively selects visual information from the environment for detailed processing through mechanisms of visual attention and saccadic eye movements. This study examines the statistical properties of the scene content selected by ...
