Pay now or pay later: aging and the role of boundary salience in self-regulation of conceptual integration in sentence processing.

Previous research has suggested that older readers may self-regulate input during reading differently from the way younger readers do, so as to accommodate age-graded change in processing capacity. For example, older adults may pause more frequently for conceptual integration. Presumably, such an allocation policy would enable older readers to manage the cognitive demands of constructing a semantic representation of the text by off-loading the products of intermediate computations to long-term memory, thus decreasing memory demands as conceptual load increases.

Gaze-contingent multiresolutional displays: an integrative review.

Gaze-contingent multiresolutional displays (GCMRDs) center high-resolution information on the user's gaze position, matching the user's area of interest (AOI). Image resolution and details outside the AOI are reduced, lowering the requirements for processing resources and transmission bandwidth in demanding display and imaging applications. This review provides a general framework within which GCMRD research can be integrated, evaluated, and guided.

Word identification and eye fixation locations in visual and visual-plus-auditory presentations of spoken sentences.

In this study, we investigated where people look on talkers' faces as they try to understand what is being said. Sixteen young adults with normal hearing and demonstrated average speechreading proficiency were evaluated under two modality presentation conditions: vision only versus vision plus low-intensity sound. They were scored for the number of words correctly identified from 80 unconnected sentences spoken by two talkers.

Perception onset time during fixations in free viewing.

In this study, we investigated when visual perception begins in fixations. During picture viewing, the picture was degraded at the beginning of selected saccades and changed back to the original after varying intervals. Participants manually responded whenever they detected changes.
