2014年1月13日 · The load theory of attention and cognitive control provides an explanation for these contrasting observations, proposing that the extent to which people can focus their attention in the face of irrelevant distractions depends on the level and type of information load involved in their current task.

In this article, we review the contributions of load theory to understand the relationship between attention, awareness and the related neural activity, while including novel data that demonstrate a novel interaction between perceptual load and the fundamental mechanisms of …

Perceptual load theory makes three main assumptions: Attentional resources are limited in capacity; Task-relevant stimuli are processed before task-irrelevant stimuli; All of the attentional resources must be used.

A load theory of attention in which distractor rejection depends on the level and type of load involved in current processing was tested. A series of experiments demonstrates that whereas high perceptual load reduces distractor interference, working memory load or dual-task coordination load increas …

2016年1月4日 · The article comprises five parts, examining (1) evidence for the effects of perceptual load on attention, (2) cognitive load, (3) individual differences under load, (4) alternative theories and criticisms, and (5) the future of load theory.

Load theory originated from combining two influential ideas: that attention has limited-capacity (Kahneman, 1973), and that all available perceptual resources will be obligatorily used to process sensory input (Treisman, 1969). This combination leads load theory to two assertions.

2004年9月1日 · A load theory of attention in which distractor rejection depends on the level and type of load involved in current processing was tested. A series of experiments demonstrates that...

In sum, load theory suggests that early selection is possible only when perceptual capacity is exhausted. When capacity is not exhausted, post-perceptual mechanisms must be invoked to inhibit irrelevant information that received perceptual processing (Macdonald and Lavie, 2008).

Lavie’s Load Theory of selective attention suggests that the quantity of stimuli presented to a person determines how their selective attention system will function – whether they will be more or less distractible (Lavie, Hirst, de Fockert, & Viding, 2004).

2014年3月17日 · Here, we review recent evidence for this proposal with an emphasis on the various subjective blindness phenomena, and their neural correlates, induced by conditions of high perceptual load. We also present novel findings that clarify the role of attention in the response to stimulus contrast.
