This study of 9 to 10-month-old fearful and non-fearful males examined the relationship of cognitive and affective variables to fear of strangers. (DP)

This study attempted to distinguish between the ambivalent response of shyness and the more potent negative affect of fear in infancy. Sixty infants between 9 and 12 months of age participated in two laboratory situations: a nonsocial situation involving the presentation of a mechanical toy; and a social situation involving a standardized stranger…

In a study of attachment behavior 10-month-old infants were observed under three conditions: with the mother, with an adult female stranger, and when both were present. Infants directed more social responses to the mother, but the stranger evoked more exploration behavior than distress. (ST)

Facial configuration and height were systematically varied as four different strangers--a male and female child, a female adult and a small female adult (midget)--each approached 40 different infants. The infants responded as if there were 3 classes of persons, suggesting that both size and facial configuration cues were used. (Author/SB)

This study explored questions concerning the specificity of facial expression of emotions in infants. A sample of 27 infants (nine each at ages 10, 11, and 12 months) were tested in six experimental and six control conditions. Two of the experimental conditions were designed to elicit fear, two happiness, and two surprise. Videotapes of the…

The development of two temperamental characteristics--the tendency to approach (uninhibited) and the tendency to avoid (inhibited) unfamiliar events--may be partially controlled by genetic predisposition. Discusses the results of a study indicating that the level of motor responses and crying in response to unfamiliar stimuli in four month olds…
