The Development of Visual Categorization Based on High-Level Cues
Peer reviewed Peer reviewed
Direct linkDirect link
Stefanie Peykarjou; Stefanie Hoehl; Sabina Pauen – Child Development, 2024
This study investigated the development of rapid visual object categorization. N = 20 adults (Experiment 1), N = 21 five to six-year-old children (Experiment 2), and N = 140 four-, seven-, and eleven-month-old infants (Experiment 3; all predominantly White, 81 females, data collected in 2013-2020) participated in a fast periodic visual stimulation…

Using Saliency Maps to Separate Competing Processes in Infant Visual Cognition
Peer reviewed Peer reviewed
Direct linkDirect link
Althaus, Nadja; Mareschal, Denis – Child Development, 2012
This article presents an eye-tracking study using a novel combination of visual saliency maps and "area-of-interest" analyses to explore online feature extraction during category learning in infants. Category learning in 12-month-olds (N = 22) involved a transition from looking at high-saliency image regions to looking at more…

Developmental Change in Infant Categorization: The Perception of Correlations among Facial Features.
Peer reviewed Peer reviewed
Younger, Barbara – Child Development, 1992
Tested 7 and 10 month olds for perception of correlations among facial features. After habituation to faces displaying a pattern of correlation, 10 month olds generalized to a novel face that preserved the pattern of correlation but showed increased attention to a novel face that violated the pattern.

Infant Response to Stimuli of Similar Hue and Dissimilar Shape-Tracing the Origins of the Categorization of Objects by Hue.
Peer reviewed Peer reviewed
Catherwood, Di; And Others – Child Development, 1989
Confirms that infants, like older children, are capable of responding categorically to stimuli of different shapes if these are similar in hue. (PCB)

Categorization and Memory Retrieval by Three-Month-Olds.
Peer reviewed Peer reviewed
Hayne, Harlene; And Others – Child Development, 1987
Infants were tested in three studies of the acquisition and long-term retention of category-specific information. Results document retention of category-specific information after intervals of two weeks. (PCB)

The Development of Hierarchical Representation of Two-Dimensional Space.
Peer reviewed Peer reviewed
Sandberg, Elisabeth Hollister; And Others – Child Development, 1996
Two studies of development of spatial representation with two dimensions found that children as young as five years use the same two independent dimensions in fine-grained spatial coding of location in a circle as adults use--radius and angle. The adult pattern, where angle as well as radius is coded hierarchically, emerges by nine years. (HTH)

Development of Face Processing: The Effect of Face Inversion.
Peer reviewed Peer reviewed
Schwarzer, Gudrun – Child Development, 2000
Examined degree to which analytic and holistic modes of processing play a role in children's and adults' categorization of faces. Found a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Seven-year-olds processed faces comparably to nonfacial visual stimuli, whereas a growing proportion…

Selective Attention Deficits in Poor Readers? Dichotic Listening, Speeded Classification, and Auditory and Visual Central and Incidental Learning Tasks.
Peer reviewed Peer reviewed
Pelham, William E. – Child Development, 1979
Results as a whole did not support the hypothesis that poor readers show deficits in selective attention relative to age-matched normal readers. (RH)

Evidence for Knowledge-Based Category Discrimination in Infancy.
Peer reviewed Peer reviewed
Pauen, Sabina – Child Development, 2002
Two studies examined whether infants' category discrimination in an object-examination task was based solely on an ad hoc analysis of perceptual similarities among the experimental stimuli. Findings indicated that 10- to 11-month- olds' responses varied systematically only with the presence of a category change, but not with the degree of…

Is a Picture Worth a Thousand Words? Preference for Auditory Modality in Young Children.
Peer reviewed Peer reviewed
Sloutsky, Vladimir M.; Napolitano, Amanda C. – Child Development, 2003
Four experiments tested the hypothesis that the importance of linguistic labels for young children's conceptual organization stems from a privileged processing status of auditory input over visual input. Findings indicated that when auditory and visual stimuli were presented separately, 4-year-olds were likely to process both kinds of stimuli,…
