Investigated relative effects of chronological age and experiential deprivation upon pictorial recognition. Four age levels (ages four to five, five to six, six to seven, and seven to eight years) and two levels of deprivation were manipulated. The 50 subjects in each factorial cell performed tasks individually. (Author/RH)

Recognition by infants, 13 and 22 weeks old, was tested by pairing novel stimuli with the familiarization stimulus at different points in an experimental session. Younger subjects showed no recognition of either two- or three- dimensional stimuli. Older subjects demonstrated more recognition in the three-dimensional condition. (MS)

Human infants' discrimination of changes in internal and external elements of compound visual patterns was investigated in four experiments employing a familiarization-novelty paradigm in which visual reinforcing patterns were presented contingent upon rate of high-amplitude nonnutritive sucking. (Author/JH)

In a visual memory task, two degrees of stimulus detail were compared to test Reese's hypothesis that stimulus detail would facilitate retention of paired associates for young children. Forty 4-year-olds and forty 5-year-olds were tested to assess reported trend that elaboration facilitates retention for older children. (JH)

The serial recall of visually presented words which were either read aloud (voiced) or read silently was examined in 3 experiments. (Editor)

Sometime before four months of age infants are capable of storing information either about the physical properties of visual stimuli or about the contigency between their response and the reinforcement. (Author)

Study is a systematic attempt to discover the relative extent to which several types of covert'' cues carry emotive communicative information. (Authors)

Attempts to improve methods employed by Uzgiris and Hunt. The longitudinal schedule of events in this experiment involved 24 infants one month old in an experimental group whose mothers were instructed to present and change a visual stimulus pattern. (WY)

Comparisons among measures of vocal and manual responses indicate the two response systems are not independent and suggest the hypothesis that processes of coordination occur with children 4 years or older that do not cccur with younger children. (Author/WY)
