Recalling episodic and semantic information about famous faces and voices

Recalling semantic information about personally known faces and voices

Retrieving semantic information from faces and voices

Semantic information is more likely to be retrieved from recognized faces than from recognized voices. Earlier studies which investigated the recall of biographical information following person recognition used famous people’s voices and faces. The present study was designed with the aim of controlling more strictly the exposure frequency to both domains of stimuli (voices and faces). Participa...

Knowledge of famous faces and names in semantic dementia.

Semantic dementia is a focal clinical syndrome, resulting from degeneration of the temporal lobes and characterized by progressive loss of conceptual knowledge about the world. Because of the highly circumscribed nature of the disorder it is a natural model for improving understanding of how semantic information is cerebrally represented. There is currently a lack of consensus. One view propose...

Semantic knowledge and episodic memory for faces in semantic dementia.

Previous studies have documented poor recognition memory for faces in patients with semantic dementia. Preserved face recognition memory was found in this study, however, so long as atrophy was confined predominantly to the left temporal lobe. Patients with structural damage to the right temporal lobe were typically impaired, with the status of the hippocampus and parahippocampal gyrus (includi...

Recalling Holistic Information for Semantic Segmentation

Semantic segmentation requires a detailed labeling of image pixels by object category. Information derived from local image patches is necessary to describe the detailed shape of individual objects. However, this information is ambiguous and can result in noisy labels. Global inference of image content can instead capture the general semantic concepts present. We advocate that high-recall holis...
