The classification of graphical elements.

In three experiments, participants classified stimuli depicting pie charts and stacked bar graphs on two criteria: a proportion shown in the graph, and the graphs overall size (scaling). Sorting times and errors were measured. For stacked bars, ...

Plasticity of feature-based selection in triple-conjunction search.

Two experiments examined the disruption of feature-based selection in triple-conjunction search at multiple target transfers. In Experiment 1, after 10 training sessions, a new target possessing previous distractor features was introduced. This produced ...

Decoding digit symbol: speed, memory, and visual scanning.

The authors evaluated the relative contributions of speed, memory, and visual scanning to Digit Symbol score in a sample of young adults (N = 87). Speed (Symbol Copy) explained 35% of Digit Symbol variance; only half of this was attributable to ...

Psychometric properties of the Hooper Visual Organization Test.

The psychometric properties of the Hooper Vsual Organization Test (VOT) have not been well investigated Here the authors present internal consistency and interrater reliability coefficients, and an item analysis, using data from a sample (N = 281) of ...

Self-discrepancies, attentional bias and persecutory delusions.

BACKGROUND: Persecutory delusions appear to involve abnormal attentional biases to threat-related information, particularly information related to the self. The present study aimed to investigate attentional biases to different types of perceived threat ...

The time course of brain activity in reading English and Chinese: an ERP study of Chinese bilinguals.

Chinese bilinguals performed a delayed naming task, reading both Chinese characters and English words, while EEGs were recorded by a 128-channel system. Principle component analysis (PCA) of Event Related Potentials (ERP) from the onset of the stimulus ...

Developmental aspects of language processing: fMRI of verbal fluency in children and adults.

We examined developmental differences, in location and extent of fMRI language activation maps, between adults and children while performing a semantic fluency task. We studied 29 adults and 16 children with echo planar imaging BOLD fMRI at 1.5 T using ...

Action generation and action perception in imitation: an instance of the ideomotor principle.

We review a series of behavioural experiments on imitation in children and adults that test the predictions of a new theory of imitation. Most of the recent theories of imitation assume a direct visual-to-motor mapping between perceived and imitated ...

Mathematical modelling of animate and intentional motion.

Our aim is to enable a machine to observe and interpret the behaviour of others. Mathematical models are employed to describe certain biological motions. The main challenge is to design models that are both tractable and meaningful. In the first part we ...

Electrophysiology and brain imaging of biological motion.

The movements of the faces and bodies of other conspecifics provide stimuli of considerable interest to the social primate. Studies of single cells, field potential recordings and functional neuroimaging data indicate that specialized visual mechanisms ...
