Subjects decided whether sentences as "The treaty passed" were "true" or "false," given number of votes cast for the bill and criterion that determined its status. An additive-stages model was applied to verification times from the present and prior studies, and was used to describe certain markedness and congruity…

When presented visual patterns for 100-msec followed by a 100-msec patterned masker at intervals of 0, 250, 500, and 2,000 msec after the offset of the stimulus, only infants in the 2,000-msec stimulus-masker interval condition significantly fixated a novel stimulus longer than a familiar stimulus. Results suggest visual processing in infants is…

Newborn infants' fixation of a graduated series of visual stimuli significantly differed in the absence and presence of white-noise bursts. Relative to the no-sound condition, sound resulted in the infants' tendency to look more at the low-intensity visual stimulus and less at the high- intensity visual stimulus. (Author/DB)

Suggests that it is sometimes useful to consider information as being encoded as images, sometimes as language, and sometimes as propositions, and describes research that provides evidence of processing in all these forms. (Author)

Investigates the extent to which kindergarten children (mean age 5.8 years) allocate their processing resources selectively to the relevant components of a visual array. (MP)

Two experiments investigated the development of verbal rehearsal strategies and selective attention in learning disabled children. In Experiment 1, Hagen's Central-Incidental task was administered to younger learning disabled and normal boys. In Experiment 2 the task was given to intermediate and older boys along with an experimentally induced…

Tested whether a verbal description given before or after presentation of a picture effected visual processing and/or memory. (SB)

Three studies investigated whether eye gaze cueing in 4-month-old infants is the result of a domain-specific module or reflects the activity of domain-general processes. In two of three experiments, infants perceived apparent motion of the pupils, and this directly elicited saccades, but only when this motion was preceded by a period of direct…

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)

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…

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…

Vidic and Haaf (2004) questioned the idea that infants use head information to categorize cats as distinct from dogs (Quinn & Eimas, 1996) and argued instead that the torso region is important. However, only null results were observed in the critical test comparisons between modified and unmodified stimuli. In addition, a priori preferences for…

The authors investigated whether the meaning of visually presented words is activated faster for early-acquired words than for late-acquired words. They addressed the issue using the semantic Simon paradigm. In this paradigm, participants are instructed to decide whether a stimulus word is printed in uppercase or lowercase letters. However, they…

Making sense of the visual world requires keeping track of objects as the same persisting individuals over time and occlusion. Here we implement a new paradigm using 10-month-old infants to explore the processes and representations that support this ability in two ways. First, we demonstrate that persisting object representations can be maintained…
