This chapter focuses on the effect of covert spatial attention on contrast sensitivity, a basic
visual dimension where the best mechanistic understanding of attention has been achieved …

In most visual search experiments in the laboratory, objects are presented on an isolated,
blank background. In most real world search tasks, however, the background is continuous …

The external noise paradigm (Z.-L. Lu & BA Dosher, 1998) was applied to investigate
mechanisms of spatial attention in location precuing. Observers were precued or …

Highly emotional events are associated with vivid “flashbulb” memories. Here we examine
whether the flashbulb metaphor characterizes a previously unknown emotion-enhanced …

In signal detection theory (SDT), responses are governed by perceptual noise and a flexible
decision criterion. Recent criticisms of SDT (see, eg, Balakrishnan, 1999) have identified …

Exogenous covert attention improves discriminability and accelerates the rate of visual
information processing (M. Carrasco & B. McElree, 2001). Here we investigated and …

Increasing the number of available sources of information may impair or facilitate
performance, depending on the capacity of the processing system. Tests performed on …

This commentary takes a closer look at how “constructive models of subjective perception,”
referred to by Collerton et al.(sect. 2), might contribute to the Perception and Attention Deficit …

Covertly attending to a stimulus location increases spatial acuity. Is such increased spatial
acuity coupled with a decreased acuity at unattended locations? We measured the effects of …

Visual abilities in deaf individuals may be altered as a result of auditory deprivation and/or
because the deaf rely heavily on a sign language (American Sign Language, or ASL). In this …
