Spatiotemporal mechanisms for detecting and identifying image features in human vision.

Our visual system constantly selects salient features in the environment, so that only those features are attended and targeted by further processing efforts to identify them. Models of feature detection hypothesize that salient features are localized ...

Inhibition of return in temporal order saccades.

Inhibition of return (IOR) is an attention mechanism that expedites the search of an object in our environment. Results in different studies support either a perceptual or motor account of IOR. One problem with the perceptual account is that IOR has not ...

Empirical evidence for independent dimensions in the visual representation of three-dimensional shape.

Three experiments investigated whether the human visual system can make independent estimations of 3-dimensional shape dimensions, as suggested by structural description models of human object recognition. Experiment 1 used a noise masking paradigm to ...

Spatial frequency discrimination in cyclopean vision.

It is well known that inspecting a cyclopean grating causes threshold for detecting a subsequently presented test cyclopean grating to be elevated, and that the threshold elevation is greatest at the adapting frequency. We report here that spatial ...

The effect of stimulus blanking on the detection of intrasaccadic displacements of translating objects.

In a display with a stationary and a translating object, subjects made a saccade towards one of the objects and had to detect intrasaccadic changes in the position of either the saccade target or the saccade flanker. Sensitivity for displacements of the ...

Visual attention and coactivation of response decisions for features from different dimensions.

The role of visual attention in task performance has been extensively debated. On the basis of the dimensional-action model, we hypothesized that a major role of attention is to transfer response decisions from targets on which it is focused to ...

The neural substrates of biological motion perception: an fMRI study.

We used fMRI to identify the brain areas related to the perception of biological motion (4 T EPI; whole brain). In experiment 1, 10 subjects viewed biological motion (a human figure jumping up and down, composed of 21 dots), alternating with a control ...

Eye contact detection in humans from birth.

Making eye contact is the most powerful mode of establishing a communicative link between humans. During their first year of life, infants learn rapidly that the looking behaviors of others conveys significant information. Two experiments were carried ...

Matching and naming objects by shape or function: age and context effects in preschool children.

Three experiments tested preschoolers use of abstract principles to classify and label objects by shape or function. Three- and 4-year-olds were instructed to match objects by shape or function. Four-year-olds readily adopted either rule, but 3-year-olds ...

Development of form similarity as a Gestalt grouping principle in infancy.

Given evidence demonstrating that infants 3 months of age and younger can utilize the Gestalt principle of lightness similarity to group visually presented elements into organized percepts, four experiments using the familiarization/novelty-preference ...
