A high density ERP comparison of mental rotation and mental size transformation.

To compare mental rotation and mental size transformation, 128-channel EEG was recorded while subjects performed both tasks using random two-dimensional shapes as stimuli. Behavioural results showed significant linear effects of both size transformation ...

Interhemispheric categorization of pictures and words.

Earlier studies suggest that interhemispheric processing increases the processing power of the brain in cognitively complex tasks as it allows the brain to divide the processing load between the hemispheres. We report two experiments suggesting that this ...

The nose smells what the eye sees: crossmodal visual facilitation of human olfactory perception.

Human olfactory perception is notoriously unreliable, but shows substantial benefits from visual cues, suggesting important crossmodal integration between these primary sensory modalities. We used event-related fMRI to determine the underlying neural ...

The Nine Box Maze Test: A measure of spatial memory development in children.

This study investigates the development of visuo-spatial memory in school-aged children, as measured by the Nine Box Maze Test Child Version (NBMT-CV). This task, originally developed for adults by, utilises an allocentric framework to assess the ...

Speed of visual processing increases with eccentricity.

The visual system has a duplex design to meet conflicting environmental demands: the fovea has the resolution required to process fine spatial information, but the periphery is more sensitive to temporal properties. To investigate whether the peripherys ...

Relationship with dynamic balance function during standing and walking.

OBJECTIVE: To investigate the relationship between dynamic balance functions in young adults and elderly adults while standing and walking. DESIGN: In standing balance tests, the Sensory Organization Test (SOT) of six combinations of three visual and two ...

Electrophysiological and haemodynamic correlates of face perception, recognition and priming.

Face perception, recognition and priming were examined with event-related functional magnetic resonance imaging (fMRI) and scalp event-related potentials (ERPs). Face perception was associated with haemodynamic increases in regions including bilateral ...

Delayed flanker effects on lateralized readiness potentials.

When participants were required to respond to a relevant central target and ignore irrelevant flanking stimuli, the flankers produced a response compatibility effect. Electrophysiological studies have shown that irrelevant flanker stimuli can affect the ...

Dopaminergic contributions to the visual categorization of natural scenes: evidence from Parkinsons disease.

Recent evidence raised the possibility that dopaminergic mechanisms in the neostriatum play an important role in categorization. In this study, we examined the electrophysiological correlates of natural scene categorization in Parkinsons disease (PD), ...

Experimental analyses of body image in the chimpanzee.

It is difficult to study body image in animals. In this study, it is assumed that the perception of the body of others reflects body image. The perception of the human face was examined in a series of six experiments with a chimpanzee. ...
