Studies of concept formation in infancy have demonstrated that certain experimental settings can elicit spontaneous behavior from infants which has been called "sorting" or "object grouping". This study pursues the issue of early sorting with infants as young as 6 months, and with a broader range of stimuli than has been used…

To investigate how a child organizes new objects and how categories function for a chid, twelve 6- and twelve 8-year-olds were individually given several sorting tasks involving 21 three-dimensional nonsense objects. The child was exposed to all the objects; three objects were pointed out and withdrawn; and then the child was asked to describe…

This study was designed as the first in a series of inquiries to investigate the use of multidimensional scaling techniques for observing and measuring underlying dimensions commonly perceived by viewers. Following a preliminary study to select photographs, 15 university students aged 19 to 45 were presented with stimuli consisting of 34 colored…

During socialization, individuals begin to understand increasingly broader and more abstract units of personal and social reality. Subjects (N=97) ranging in age from 13 to late middle age completed a linguistic task in which they could impose higher order conceptions on lower order descriptions by identifying different level similarities within…

Piaget, in describing the sequence of classificatory development, describes class inclusion as composed of two processes; hierarchical classification and post-whole comparisons. In the experiment reported here, elementary school children, trained in the concept of sets in first grade mathematics were given a task where they were required to assess…

This monograph has four main objectives: (1) to define the field of ergometrics, (2) to identify some potential applications of ergometrics to problems in occupational or career education, (3) to review the relevant research literature, and (4) to suggest some conceptual approaches that might be used in conjunction with ergometric procedures.…

This study was designed (1) to determine differences in classificatory skills of low socioeconomic status children under intervention and non-intervention conditions; (2) to determine differences in classification skills of bilingual, biliterate, and monolingual students; and (3) to study differences in classificatory skills as a function of age.…
