When shown a pair of digits and asked to select the larger of the two, subjects make their choice more quickly as the numerical difference between the digits increases. Presents and tests a semantic coding model that can explain this and all previous results. (Editor)

Three experiments examined the role of various sources of feedback in the development and maintenance of a complex ballistic skill, dart throwing, using extended practice. (Editor)

In recent years several models of human-information processing have been proposed in which the central component is a limited-capacity processing system. One line of research has focused on the question of which stages in the processing sequence require capacity in this system. This research is concerned with time and capacity demands in…

There are many tasks in which people are called on to disregard information that they have already processed. Dealing with inadmissible evidence in a courtroom setting, second-guessing the past, etc. This research investigates such difficulties in a general form, using almanac-type questions. (Editor/RK)

Three experiments were conducted to evaluate the P300 component of the human evoked response as an index of bisensory information processing. Data shows that the P300 promises to be a valuable tool for assessing brain processes during complex decision making. (Editor/RK)

In 1974 Wood proposed a hybrid serial-parallel model to account for the within-stimulus interactions between the acoustic cue of "pitch" and the phonetic cue of "place". These experiments found Wood's research independent of his subjects' experience, the order of cue presentation, and whether the cues are presented simultaneously or sequentially.…
