A multiple habituation paradigm was used to determine whether 10- to 12-month-old infants were able to discriminate between visual arrays differing only in their numerosity. (Author/RH)

Investigated relationships between mothers' perception of infants temperament at 6 months and their behavior toward their infants at 6 and 12 months of age among 40 firstborn Israeli infants. Temperamental intensity ratings were related to auditory stimulation and contingent positive vocalization for girls and to increased physical contact for…

The effects of children's gender perceptions of infants as "like me" or "not like me" on their behavioral interest in infants were experimentally manipulated. Thirty-seven boys and 34 girls at two age levels were observed in 10-minute encounters with unfamiliar seven-month-old infants and their mothers. (Author/RH)

Four-, six, and eight-month-old infants' perception of the multimodal features of the human face was investigated. Results show that speech-related exaggerated prosody cues facilitate detection of the audible features of multimodally represented faces, but not until six months of age. (Author/DR)

The fundamental frequencies (Fo) of infant cries were analyzed to determine if mean cry Fo differed as a function of the infant's sex or due to the stimulus evoking the cry. Results indicate no significant differences in either; however, males exhibited a tendency to have higher mean Fo. (Author/KM)

Interactions of adults with a single infant, dressed as either a male or female, were recorded and analyzed for direction of gaze, facial expression, physical contact, and toys used. Interviews followed. Results shows that both male and female parents behave differently toward unfamiliar infants on the basis of perceived sex. (AOS)

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)

This study found race and sex differences with regard to proximity, smiling, and touching among preschoolers who posed for photographs with a same-sex peer and with an infant. (PCB)

The primary purpose of this study was to examine whether a general perceptual model developed by Vitz and Todd (1971), capable of dealing with multiple determinants of attending, is useful for understanding infant attending. The model, previously used in research with adults, assumes that perception can be represented as a stochastic sampling…

This paper presents results of the first part of a research program designed to test the hypothesis that an hour of extra contact between mother and infant beginning about one half hour after delivery would be associated with more secure attachment of an infant to its mother at one year. In the overall study extra contact infants were also…

This study uses a habituation paradigm to systematically investigate the discrepancy hypothesis with male and female new borns. In addition, multiple visual response measures are used in monitoring the habituation process and the infant's response to various degrees of novelty. Ss were 36 apparently normal newborns (half of each sex) ranging in…

Outlines a study which examines adult interpretations of infant nonverbal behavior. Contends that negative nonverbal emotions are more likely to be attributed to male infants, and positive nonverbal emotions are more often attributed to female infants. (MH)

Examined role of grandparents in infancy in comparative analysis of grandparent-infant grandchild and parent-infant interaction patterns. Results revealed that both grandmothers and grandfathers were active interactive and support agents, with pattern of similarities and differences in interactive style across generation and gender. (Author/NB)

Examines 95 parents' reports of relations between infant termperament and parental psychological conditions, as well as familiy characteristics of socioeconomic status, birth order, and infant gender. (HOD)
