When other individuals move, we interpret their movements as discrete, hierarchically-organized, goal-directed actions. However, the mechanisms that integrate visible movement features into actions are poorly understood. Here, we consider two sequence learning mechanisms--transitional probability-based (TP) and position-based encoding…

How are spatial and object attention coordinated to achieve rapid object learning and recognition during eye movement search? How do prefrontal priming and parietal spatial mechanisms interact to determine the reaction time costs of intra-object attention shifts, inter-object attention shifts, and shifts between visible objects and covertly cued…

This paper studies the dynamics of attempting to access two spatial memories simultaneously and its implications for the accuracy of recall. Experiment 1 demonstrates in a range of conditions that two cues pointing to different experiences of the same object location produce little or no higher recall than that observed with a single cue.…

Six experiments involving a total of 112 college students demonstrate that a robust memory for visual context exists to guide spatial attention. Results show how implicit learning and memory of visual context can guide spatial attention toward task-relevant aspects of a scene. (SLD)

The hypothesis that describing a visual memory can result in recoding interference was investigated in a series of 6 experiments with 518 college students. Collective results were consistent with the hypothesis; verbalizing memory can produce a verbally biased memory representation that can interfere with the original visual memory. (SLD)

Experiments tested the predictions that words are perceived more accurately in strongly constraining word contexts than in weakly constraining word contexts, and that a strong perceptual advantage would be present for letters in words vs. letters alone or in unrelated-letter strings. Several alternative theories of word perception are discussed.…
