Elementary school students were tested on a visual search task where letter matching was based on the visual or name characteristics of letters. Visual match lists were searched faster than name match lists by all three grades. (SBT)

Two groups of kindergarten children received stimulus differentiation training either with feedback (experimental Ss) or without (controls), prior to presentation of a series of discrimination-learning problems using blank-trial probes. Findings are discussed in relation to theoretical perspectives derived from Piagetian theory and developmental…

Investigates preschool children's ability (n = 30) to discriminate age, and subject's use of different facial areas in ranking facial photographs into age order. Results indicate subjects from 3 to 9 years can successfully rank the photos. Compared with other facial features, the eye region was most important for success in the age ranking task.…

Liniar functions fitted to the proportion of optional reversal shifts as a function of log CA were used to assess the effect of stimulus and training variables on the development of reversal-shift. (ST)

The question of how children represent and use comparative or partially ordered information is examined. Two experiments tested a conjecture that a common representation, a linear order, underlies the processing of all comparatives. (Author/MS)
