The ability of young infants between the ages of 8 and 17 weeks to perceive outline shapes was investigated in nine experiments using an habituation paradigm. (JMB)

Investigates the question of whether or not the ability to distinguish between veridical and imaginal memory representations changes with age. Subjects were 64 children from second, fourth and sixth grades, and 16 college students. (Author/MP)

The schema hypothesis proposed by Kagan and Lewis was used to make predictions concerning the preferences of infants 3 to 14 months old for speech stimuli. An operant response method was used in determining the infants' preferences for inflected, monotone, and scrambled natural speech stimuli. (MS)

It was hypothesized that because of differential social learning, females would report fear of spiders more frequently than males would but that males selected for equal self-report of fear would show greater autonomic responsivity than women to slides of spiders. (Editor)

Older individuals have been reported to use imagery mediation less in remembering verbal material. To determine whether this is due to decrease in the speed with which verbal stimuli are recoded into pictorial representations, the reaction time of 12 old (63-78) and 12 young (17-25) subjects for matching verbal descriptions to geometric shapes was…

A new procedure for estimating the dichotic ear advantage is applied for the first time in conjunction with the single-response requirement. Most subjects showed unusually large right-ear advantages, making the present methodology interesting for the study of hemispheric asymmetry. (Editor)

Author states that Csikszentmihalyi's flow model seems to be contradictory in distinguishing play as an activity undertaken for the individual's enjoyment of the process itself and play as an extrinsically motivated, goal-oriented activity. (RW)

In reply to Barnett's article, Csikszentmihalyi states that the individual's intrapsychic needs and response to external stimuli are interwoven and cannot be separated into two distinct motivating factors. (RW)

Investigates how the inhibition and latency-reduction effects interact with each other and how they change with changes in the intensity of the startle-eliciting stimulus. (Author/RK)

Three converging procedures were used to determine whether pictures presented in a rapid sequence at rates comparable to eye fixations are understood and then quickly forgotten. (Editor)

Evidence for the hypothesis that the appearance of visually presented words is stored in "literal copy" form is critically evaluated and shown to be inconclusive. An experiment in which students were required to retain information about zero, one, or two visual properties of words is reported. (Editor)

Subjects worked on a problem, engaged in an intervening activity, and then resumed work on the problem. Different intervening activities represented various mechanisms that produce incubation (e.g., set breaking, facilitation by analogy, review of the problem's elements). These various treatment groups were compared to a control group that worked…

The effects of vocalized tests on paired-associate learning were compared with those of silent tests and of blank trials by using six conditions, each repeating a pattern of six cycles including one study trial. (Editor/RK)

To test the hypothesis that meaning of a sentence is represented in an abstract format rather than one mediated by words or images, 96 spoken sentences were immediately followed by a word or drawing probe. It was concluded that sentence or probe meaning is represented in an abstract conceptual format. (CHK)
