Matell, Matthew S.; Della Valle, Rebecca B. – Learning & Memory, 2018
Presentation of a previously trained Pavlovian conditioned stimulus while an organism is engaged in operant responding can moderate the rate of responding, a phenomenon known as Pavlovian-to-instrumental transfer. Although it is well known that Pavlovian contingencies will generate conditioned behavior that is temporally organized with respect to…

Patching, Geoffrey R.; Englund, Mats P.; Hellstrom, Ake – Journal of Experimental Psychology: Human Perception and Performance, 2012
Despite the importance of both response probability and response time for testing models of choice, there is a dearth of chronometric studies examining systematic asymmetries that occur over time- and space-orders in the method of paired comparisons. In this study, systematic asymmetries in discriminating the magnitude of paired visual stimuli are…

Li, Winston; Meekins, Kelsey; Schirillo, James – Neuropsychologia, 2012
In an experimental paradigm adapted from Hari (1995), forty observers listened via headphones to 8 binaural clicks: 4 left-ear leading followed by 4 right-ear leading with either 38 or 140 ms interstimulus intervals (ISIs). Concurrently, they viewed either foveal or peripheral visual stimuli designed to activate either the parvocellular or…

Chen, Yi-Chuan; Spence, Charles – Journal of Experimental Psychology: Human Perception and Performance, 2011
We report a series of experiments designed to demonstrate that the presentation of a sound can facilitate the identification of a concomitantly presented visual target letter in the backward masking paradigm. Two visual letters, serving as the target and its mask, were presented successively at various interstimulus intervals (ISIs). The results…

Mayr, Susanne; Buchner, Axel – Journal of Experimental Psychology: Human Perception and Performance, 2006
Four experiments are reported in which the mechanisms underlying auditory negative priming were investigated. In Experiments 1A and 1B, preprime-prime intervals and prime-probe intervals were manipulated.The ratio between the 2 intervals determined the size of the negative priming effect. Results are compatible with the episodic retrieval account,…

Smith, W. Carter; Johnson, Scott P.; Spelke, Elizabeth S. – Cognitive Psychology, 2003
Although much evidence indicates that young infants perceive unitary objects by analyzing patterns of motion, infants' abilities to perceive object unity by analyzing Gestalt properties and by integrating distinct views of an object over time are in dispute. To address these controversies, four experiments investigated adults' and infants'…
