A naming task using primary and secondary hues and achromatic stimuli was given to 669 preschool children. Results showed age and sex differences in performance and revealed an acquisition order similar to that found in related research and also similar to the proposed evolutionary order across cultures.

Discrimination learning studied in 3-year-olds, indicated that children over 30 months of age did better than younger children, and girls learned faster than boys after the first problem. (ST)

The ability of 40 children four and five years of age to discriminate reflections and rotations of visual stimuli was examined in a kinetic imagery task. Results revealed that prediction accuracy was associated with the existence of orientation markers on the stimuli, as well as age, sex, type of discrimination, and several interactions among the…

Using a visual conditional stimulus and an auditory unconditional stimulus in a trace procedure, the heart rate conditioning of 16 infants ranging in age from two to seven months was evaluated. (MP)

The emotional impact of televised interpersonal dramas was investigated, with specific emphasis being given to age- and gender-related differences in children's spontaneous nonverbal expressive reactions. Participants were 27 female and 22 male children in three age groups: 4-5, 7-8, and 13-14 years. Facial expressions were unobtrusively…

Reports that form matching increased with age both in number of subjects with reliable preferences and in strength of preferences, but that at all ages form matches predominated. (Author/DR)

A total of 20 neonates were presented with mild intensity blue or blue-green light during presentation of habituation and dishabituation stimuli. Orienting and defensive responses were measured by monitoring heart rate deceleration. (GO)

Children's abilities to judge "who is older" without using size as a cue were studied. Five-year-olds were better able to discriminate age than four-year-olds but were not equal to adults. No significant sex differences were found. (Author/RD)

Examined children's emotional and cognitive responses to emotionally evocative vignettes. Results indicated age-related increases in children's responses. Found limited increases with age in children's concordant emotions, or emotions identical to emotions of persons in the vignettes, and continuous increases with age in children's attributions…

Children's temporal comprehension was assessed after viewing a television program containing flashbacks that shifted the events to much earlier times. Flashbacks were marked or not marked with sound effects, and time relations were represented with either dreamy dissolves or abrupt camera cuts. A total of 64 children, equally distributed by sex…

This study compares the free recall of small common objects as perceptual stimuli in normal male and female children of two age levels (8 years and 12 years). The data show that girls are superior to boys in free recall, and with increasing age, capacity to recall increases. Eight-year-olds evidence clustering in their organized recall of concrete…

A sample of school children, ages 7-11, was given a range of short-term memory tests to determine whether recall was optimised by aural or by visual stimuli presentation. Results showed that for both sexes and for each age group aural presentation was consistently superior to visual. (Author)

Seventy two first, second and third grade boys and girls were administered seriation problems involving different combinations of shape and color variation. Success rates and latency scores were influenced by shape variation, but not by color variation or grade level. (BD)
