A series of experiments tested a recent suggestion that vertical symmetry of a stimulus display can serve as a visual diagnostic for responding "same" in a letter-matching task. The data of chief interest were same reaction times to vertically symmetric (e.g., AA) and asymmetric (e.g., LL) displays, each composed of two side-by-side uppercase…

Comparisons between recall levels following simple acoustic or visual tasks and the simultaneous visual-plus-acoustic task are not based upon equivalent amounts of interference within each modality. This research attempts to test more precisely the relationship between visual and acoustic interference by using a sequential rather than a…

Structural and semantic levels of processing were distinguished in two experiments that varied stimulus meaningfulness in an incidental learning paradigm. (Editor)

A recognition memory experiment investigated memory scanning when stimuli were organized but not easily labeled verbally. The principle findings indicated that the organization of the to-be-remembered sets had a pronounced influence on performance. (Editor/RK)

Memory for sequences of briefly presented letters was examined to discover the effects of intraserial repetition and acoustic contrast on recall of a critical letter pair. (Editor)

Attempts to establish the degree of perspective convergence, which the Western observer will accept as a realistic portrayal of objects drawn in perspective, and to determine the relationship between acceptable convergence and viewing conditions. (Author/RK)

An overt rehearsal procedure was used to investigate the relationship between children's rehearsal strategies and free recall performance. Subjects were 72 third- and 72 sixth-grade children. Investigated were the effects of increased processing time and rehearsal training upon recall. (MS)

This research on eyelid conditioning was designed to evaluate the contributions of sensory, associative, and criterion effects with variations in the interstimulus interval. (Editor/RK)

Presents a speed-accuracy tradeoff method for studying the dynamics of memory retrieval in recall that may be useful in studying the relationship between recall and recognition. Describes the method and uses it to compare retrieval dynamics in recall and recognition as a function of the presence or absence of associative inference. (Author/RK)

Children aged four through six years were given identical addition and subtraction calculations presented in three problem-type formats: nonverbal problems, story problems, and number-fact problems. Results suggest that children's earliest calculation ability is based on experiences combining and separating sets of objects. Contains 34 references.…

Studied the organization of arousal and attention processes in 138 neurologically at-risk neonates by examining visual preferences when infants were in 3 arousal conditions that involved light panel stimuli. There were no differences in preferences in the two conditions that caused the most arousal. (LB)

Summarizes the use of field experiments designed to investigate personal space invasion. States that the experiments were designed and conducted by introductory psychology students and complemented by classroom lectures. Reports that the experiments provided an understanding of personal space, personal space invasion, and the implications…

This study tested the presence of the face inversion effect in 4-month-old infants using habituation to criterion followed by a novelty preference paradigm. Results of Experiment 1 confirmed previous findings, showing that when 1 single photograph of a face is presented in the habituation phase and when infants are required to recognize the same…

The authors examined the evolution of cognitive and emotional responses to terror risks for a nationally representative sample of Americans between late 2001 and late 2002. Respondents' risk judgments changed in ways consistent with their reported personal experiences. However, they did not recognize these changes, producing hindsight bias in…

Thirty-four undergraduates used Web-based self- and peer-assessment procedures for evaluating proposals in experimental psychology courses. Students presented their proposals and commented on the proposals of others on the Web. Results indicated that proposal observation and peer interaction enhanced the quality of students' proposals. These…
