Updating and maintenance of information are 2 conflicting demands on working memory (WM). We examined the time required to update WM (updating latency) as a function of the sequence of updated and not-updated items within a list. Participants held a list of items in WM and updated a variable subset of them in each trial. Four experiments that vary…

Early verbal-memory researchers assumed participants represent memory of a pair of unrelated items with 2 independent, separately modifiable, directional associations. However, memory for pairs of unrelated words (A-B) exhibits associative symmetry: a near-perfect correlation between accuracy on forward (A??) and backward (??B) cued recall. This…

The purpose of the recently proposed "p[subscript rep]" statistic is to estimate the probability of concurrence, that is, the probability that a replicate experiment yields an effect of the same sign (Killeen, 2005a). The influential journal "Psychological Science" endorses "p[subscript rep]" and recommends its use…

R. F. Wang and E. S. Spelke's (2000) finding that disorientation disrupts knowledge is consistent with egocentric but not allocentric coding of object location. The present experiments tested the hypothesis that egocentric coding may dominate early on but that once an allocentric representation is established, then target location is retrieved…

A model was proposed as an alternative to current models for categorical perception, which refers to the apparent responding to stimuli only in absolute terms. The model proposed that a single (common) factor causes both a peak in the discrimination function and a categorical dichotomy and thus the correlation between the two. (Editor/RK)

Most studies of memory emphasize the direct encoding of physical stimuli. In contrast, this research investigates memory for the internal stimuli that are generated during processing of a presented stimulus. (Editor)

In two experiments, recognition accuracy was compared between subjects who made frequency judgments and subjects who made recognition judgments. Results indicate that at least partially different information in memory is evaluated when judging frequency than when making recognition judgments and that this information facilitates recognition…

Attempts to settle the question of whether reading units are ever larger than letters and considers the variables expected to influence the size of the reading unit. (Author/RK)

In the first of two experiments investigating the inhibitory effect of cuing, the taxonomic frequencies of cue words and critical words were manipulated orthogonally. (Editor)

Tulving and Thomson's encoding specificity effect was examined as a function of grammatical class and concreteness of the cues. (Editor)

Presents three experiments that explore whether inescapable shock of long duration and moderate intensity (LoShk) produces an avoidance-escape deficit (called an interference effect) by causing animals to learn to respond less actively or by causing them to learn to be "helpless". (Editor)

Grant and Roberts found that houselight presented throughout the delay period on a delayed matching-to-sample task caused pigeons to demonstrate a much lower level of accuracy than was found when the delay was spent in darkness. A series of experiments was carried out to examine possible mechanisms responsible for this light-induced retroactive…

A series of experiments demonstrate that (a) temporal and spatial structures may be coded independently of one another, (b) linguistic materials lead to temporal superiority whereas pictorial forms give rise to temporal/spatial equality, (c) imposed encoding strategies do not influence the above patterns, and (d) imaginal processing does not…

Attempts to help specify the boundary conditions for use of the recognition-recall method, i.e., recall made conditional upon recognition, and to use this method to evaluate a hypothesis about stimulus-concreteness effects with low-meaningful responses. (Author/RK)

These experiments consider similarities and differences between classifications of pictorial and verbal stimuli in order to investigate whether the kinds of information used differ depending on the stimulus class. Three hypotheses regarding the information used in picture and word classification were evaluated. (Author/RK)
