Ortega, Laura; Guzman-Martinez, Emmanuel; Grabowecky, Marcia; Suzuki, Satoru – Journal of Experimental Psychology: Human Perception and Performance, 2012
Several seconds of adaptation to a flickered stimulus causes a subsequent brief static stimulus to appear longer in duration. Nonsensory factors, such as increased arousal and attention, have been thought to mediate this flicker-based temporal-dilation aftereffect. In this study, we provide evidence that adaptation of low-level cortical visual…

Rhodes, Gillian; Jeffery, Linda; Boeing, Alexandra; Calder, Andrew J. – Journal of Experimental Psychology: Human Perception and Performance, 2013
Despite the discovery of body-selective neural areas in occipitotemporal cortex, little is known about how bodies are visually coded. We used perceptual adaptation to determine how body identity is coded. Brief exposure to a body (e.g., anti-Rose) biased perception toward an identity with opposite properties (Rose). Moreover, the size of this…

Anderson, David E.; Vogel, Edward K.; Awh, Edward – Journal of Experimental Psychology: Human Perception and Performance, 2013
Perceptual grouping can lead observers to perceive a multielement scene as a smaller number of hierarchical units. Past work has shown that grouping enables more elements to be stored in visual working memory (WM). Although this may appear to contradict so-called discrete resource models that argue for fixed item limits in WM storage, it is also…

Huber, David E.; Tian, Xing; Curran, Tim; O'Reilly, Randall C.; Woroch, Brion – Journal of Experimental Psychology: Human Perception and Performance, 2008
This article presents data and theory concerning the fundamental question of how the brain achieves a balance between integrating and separating perceptual information over time. This theory was tested in the domain of word reading by examining brain responses to briefly presented words that were either new or immediate repetitions. Critically,…

Witt, Jessica K.; Proffitt, Dennis R.; Epstein, William – Journal of Experimental Psychology: Human Perception and Performance, 2005
Recent research demonstrates neurologic and behavioral differences in people's responses to the space that is within and beyond reach. The present studies demonstrated a perceptual difference as well. Reachability was manipulated by having participants reach with and without a tool. Across 2 conditions, in which participants either held a tool or…

Friedman, Alinda; And Others – Journal of Experimental Psychology: Human Perception and Performance, 1982
Two experiments tested the limiting case of a multiple resources approach to resource allocation in information processing. Results contradict a single-capacity model, supporting the idea that the hemispheres' resource supplies are independent and have implications for both cerebral specialization and divided attention issues.

Ledlow, Alexa; And Others – Journal of Experimental Psychology: Human Perception and Performance, 1978
The physical identity reaction time task used in this study was designed to further test the effect of processing mode uncertainty on visual field asymmetries that Swanson et al. (1974) reported, and to determine the effects of location uncertainty in a cognitive task. (Author/KC)
