Paying Attention to Social Meaning: An fMRI Study

Paying attention to social meaning: an FMRI study.

Animations of simple geometric shapes are readily interpreted as animate agents engaged in meaningful social interactions. Such animations have been shown to activate brain regions implicated in the detection of animate motion, in understanding the intentions of others as well as areas commonly linked to the processing of social and emotional information. However, attribution of animacy does no...

Paying attention to meaning.

Several paradigms show that responses to one event compromise responses to a second event for around 500 ms. Such effects are generally attributed to attentional capacity limitations associated with processing information in the first event. In a task in which targets could be distinguished only by their meaning, we varied the semantic relationship between distractors and targets following at d...

Paying Attention to Memory

Paying attention to emotion: an fMRI investigation of cognitive and emotional stroop tasks.

In this research, we investigated the degree to which brain systems involved in ignoring emotionally salient information differ from those involved in ignoring nonemotional information. The design allowed examination of regional brain activity, using fMRI during color-word and emotional Stroop tasks. Twelve participants indicated the color of words while ignoring word meaning in conditions in w...

Paying Attention to Symmetry

Humans are very sensitive to symmetry in visual patterns. Symmetry is detected and recognized very rapidly, and eye fixations are concentrated along the axis of symmetry or the symmetrical center of the patterns. This suggests that symmetry is a highly salient feature. Existing computational models of saliency, however, have mainly focused on contrast as a measure of saliency. These models do n...
