J. S. Joseph, M. M. Chun, and K. Nakayama (1997) found that pop-out visual search was impaired as a function of intertarget lag in an attentional blink (AB) paradigm in which the 1st target was a letter and the 2nd target was a search display. In 4 experiments, the present authors tested the implication that search efficiency should be similarly…

Vision assessments were provided to 297 preschoolers in nine Head Start programs in New York State. The protocol used provided a thorough evaluation and required only seven minutes per child. Sixty-three children (21.2%) were referred for further evaluation. Visual deficits detected included decreased acuity, strabismus, astigmatism, and…

Studies have suggested attention-free semantic processing of natural scenes in which concurrent tasks leave category detection unimpaired (e.g., F. Li, R. VanRullen, C. Koch, & P. Perona, 2002). Could this ability reflect detection of disjunctive feature sets rather than high-level binding? Participants detected an animal target in a rapid serial…
