Children and adults learned associations between line length and color. Subjects were then presented with pairs of colors and asked to choose the color that had been associated with the longer line. For all ages, choice reaction times were related to differences in, and ratios of, line lengths. (BC)

Two experiments examined the hypothesis that aging is associated with an increase in schema-related influences on memory performance. Attention allocated during the study was disrupted more by lack of scene organization in older adults. There were relatively systematic age differences for retention. (RH)

Three groups of 12-month-old infants were tested for cross-modal and intramodal transfer of information about shape. Infants were given either visual or tactual familiarization and then tested for visual or tactual recognition. Overall, intramodal transfer was superior to cross-modal transfer. Cross-modal asymmetries were found for which possible…

Examined instrumental learning in premature infants by providing 45 infants at 33 weeks conceptual age with either a teddy bear that "breathed" quietly at the infant's respiration rate (BB) or a nonbreathing bear (NBB). Over a two-week period, infants provided with the BB decreased their latency to contact the bear; infants exposed to the NBB…

Seven experiments studying the relations among different measures of visible and informational persistence after a physical stimulus involving 52 undergraduate and graduate students rely on state-trace analysis to develop a theory of these two types of persistence in the context of visual-information processing. (SLD)

Explored the role of motion versus shape in children's categorization of animal and non-animal kinds. Found that 4-year olds significantly used motion cues over shape cues to categorize objects. Seven-year olds and adults tended to use motion more than shape to categorize animals but not geometric figures. Findings support view that children are…

Four-year olds, 6-year olds, and adults were given a computer-game mental rotation task, but with no instructions on mental rotation or other mental activity. Reaction time patterns and verbal reports revealed that 6-year olds were comparable to adults in spontaneous use and subjective awareness of mental rotation. Four-year olds who referred to…

Examined influence of object labels and shape similarity on 16- to 21-month-olds' inferences. Found that infants generalized non-obvious property of unlabeled objects to test objects with highly similar shapes. For objects labeled with novel nouns, infants relied on shape similarity and shared labels to generalize properties. For objects labeled…

Two experiments examined 6-month-olds' ability to discriminate between visual displays of various number of dots varying in size and position, and with controls for other extraneous variables. Findings indicated that infants could discriminate between large sets on the basis of numerosity if they differed by a large ratio (8 versus 16, but not 8…

Individuals often claim that they vividly remember information with negative emotional content. At least two types of information could lead to this sense of enhanced vividness: Information about the emotional item itself (e.g., the exact visual details of a snake) and information about the context in which the emotional item was encountered…

The ability to perform induction appears early; however, underlying mechanisms remain unclear. Some argue that early induction is category based, whereas others suggest that early induction is similarity based. Category- and similarity-based induction should result in different memory traces and thus in different memory accuracy. Performing…

In 4 studies, 7.5-month-olds used synchronized visua-lauditory correlations to separate a target speech stream when a distractor passage was presented at equal loudness. Infants succeeded in a segmentation task (using the head-turn preference procedure with video familiarization) when a video of the talker's face was synchronized with the target…

Studies on functional hemispheric asymmetries have suggested that the right vs. left hemisphere should be predominantly involved in low vs. high spatial frequency (SF) analysis, respectively. By manipulating exposure duration of filtered natural scene images, we examined whether the temporal characteristics of SF analysis (i.e., the temporal…

The natural input memory (NAM) model is a new model for recognition memory that operates on natural visual input. A biologically informed perceptual preprocessing method takes local samples (eye fixations) from a natural image and translates these into a feature-vector representation. During recognition, the model compares incoming preprocessed…

Previous research has suggested that persons with mental retardation evidence equivalence more readily after being trained on auditory-visual than on visual-visual match-to-sample tasks. The present study sought to determine if this discrepancy is also apparent in normally capable preschoolers and whether the derived class-consistent test…
