“…The present results join other studies of the development of perceptual classification performance in showing that it is inappropriate to describe the young child as guided by a holistic mode of responding (e.g., Aschkenasy & Odom, 1982;Cook & Odom, 1988, 1992Odom & Cook, 1984). Furthermore, using a concept-learning task, Ward, Vela, and Duffin Hass (1990) found that preschool children, elementary children, and adults learned family-resemblance categories with single-and dual-attribute analytic modes.…”

“…Previous triad classification task studies have also uncovered individual differences within age groups in classification performance (e.g., Aschkenasy & Odom, 1982;Cook & Odom, 1988;Wilkening & Lange, 1987). For example, Aschkenasy and Odom (1982) used a modified version of the triad classification task to determine which of two stimulus dimensions appeared more salient to each child.…”

“…Subsequent findings showed that preschool children sometimes make dimensional classifications of adult-separable stimuli (Aschkenasy & Odom, 1982;Cook & Odom, 1988;Odom & Cook, 1984;L. Smith, 1983L.…”

The nature of perceptual classification was investigated in children ranging between 4 and 10 years, and in young adults. Triad classification task responses were categorized as consistent or inconsistent with several classification rules, including: overall-similarity, size-dimensional, brightness-dimensional, pure identity, and all combinations of a switch from one rule to another midway through the experiment. The rule with the highest proportion of responses consistent with it reflected each person's best-fitting rule pattern. The higher this value, the higher the assumed consistency of rule usage. Data from the majority of individuals in every age group conformed best to one of the three dimensional rules. In addition, the consistency values for individuals' best-fitting rule became significantly higher as age increased. It is concluded that most children have a tendency to attend selectively to one stimulus dimension when making perceptual classification judgments. The developmental trend in perceptual classification does not appear to be a holistic-to-analytic shift; instead, it is a trend toward greater consistency in following a given classification rule.

“…Another interesting issue in the comparison between haptic and visual perception relates to the differences at the level of global and local processing (Cook & Odom, ; Garner, ). Berger and Hatwell () showed that analytical strategies predominate over holistic strategies in haptic perception.…”

Local and Global Processing in Blind and Sighted Children in a Naming and Drawing Task

This study investigated the spatial analysis of tactile hierarchical patterns in 110 early-blind children aged 6-8 to 16-18 years, as compared to 90 blindfolded sighted children, in a naming and haptic drawing task. The results revealed that regardless of visual status, young children predominantly produced local responses in both tasks, whereas the production of integrated responses emerged later. Development of local and global processing seems to proceed similarly in the two populations, but local processing continued to occur at high levels over a larger age range in the blind. The possibility of visual mediation is pointed out, as totally blind children tended to process information locally more often than blind children with minimal light perception.

“…At least some developmental studies on free classification show evidence for the formation of rule-based representations during childhood. Both children and adults categorize stimuli that vary on two dimensions, on the basis of a single dimension (Cook and Odom, 1988, 1992; Wilkening and Lange, 1989; Thompson, 1994; Raijmakers et al, 2004). The developmental changes that do occur in those studies mostly concern the consistency of classification (Thompson, 1994), and the relative salience of the stimulus dimensions (cf.…”

Classification based on multiple dimensions of stimuli is usually associated with similarity-based representations, whereas uni-dimensional classifications are associated with rule-based representations. This paper studies classification of stimuli and category representations in school-aged children and adults when learning to categorize compound, multi-dimensional stimuli. Stimuli were such that both similarity-based and rule-based representations would lead to correct classification. This allows testing whether children have a bias for formation of similarity-based representations. The results are at odds with this expectation. Children use both uni-dimensional and multi-dimensional classification, and the use of both strategies increases with age. Multi-dimensional classification is best characterized as resulting from an analytic strategy rather than from procedural processing of overall-similarity. The conclusion is that children are capable of using complex rule-based categorization strategies that involve the use of multiple features of the stimuli. The main developmental change concerns the efficiency and consistency of the explicit learning system.
