Theories and descriptions of various infant fear behaviors are presented in this paper. Five examples of fear are given: (1) learned fear, in which the infant associates some unpleasant action with an agent, (2) unlearned fear, in which the infant experiences an intense sensory phenomena such as a loud noise, (3) stranger anxiety, (4) fear caused…

This study examined the reactions of 45, 10-month-old infants to peer strangers. The infants were observed in two conditions: with a stranger of the identical age (10 months) and with one who was younger (5 months). In additon, each infant's behavior when he was alone with his mother was compared to his behavior when he was in the presence of…

This paper reports a study which investigated 2-month-old infants' auditory discrimination of tone quality in the male voice, extending a previous study which found that voice quality changes (soft versus harsh) in a female voice were discriminable by infants at this age. Subjects were 20 infants, tested at 8 and 9 weeks of age. Each infant was…

This study examined the dynamic organization of interactions specific to attachment groups in a learning situation. Participating were 62 mothers and their 12- to 16-month-olds, observed in the laboratory during three 3-minute learning tasks. After the laboratory session was completed, the Strange Situation procedure was conducted. Findings…

Whether maternal touching of the infant while speaking to him or her about a stranger facilitates or interferes with social referencing is investigated in this study. Thirty-three 10-month-olds received positive or neutral nonverbal messages when their mothers spoke to them about a stranger. Infants whose mothers did not touch them while speaking…

Studies on peer interaction in infancy seem to imply that social group structure emerges from infants' and toddlers' dyadic interactions. In contrast to this position, the present study hypothesizes that attention structure may be a major precursor for social group structure. To investigate that possibility, an attempt was made to develop a…

Examined are developmental changes in infants' strategies for using adults instrumentally to achieve goals. Data were derived from longitudinal observations of 1 girl and 1 boy twin individually interacting with 21 somewhat or totally unfamiliar adults at 2- or 3-week intervals from the age of 4 to 15 months, inclusive. Videotapes of interactions…

Human infants are sensitive from birth to some intrinsic properties of objects; they are also sensitive to position. During the first weeks of life, pertinent dimensions of differentiation between objects are relative to global properties of the entire object or pattern. Position is defined by the direction of a displacement: the trajectory…

This paper reviews research on the relationship between infant temperament and maternal caregiving, and discusses conflicting findings. After emphasizing the central importance of independent measures in tests of interactions between temperament and caregiving, the paper reports two studies designed to clarify the relationship. In Study One, 48…

In an attempt to address the issue of bimodal coordination of featural stimuli, the sensitivity of 3-month-old infants to the auditory and visual components of male and female stimulus configurations was examined. Measures were made of the infants' visual attention to a male or female face while they listened to a male voice, female voice, or to…

The ability of 5-month-old infants to recognize two-dimensional (pictorial) representations of three-dimensional objects was investigated. Subjects were 24 5-month-old infants. The novelty preference technique was employed: all infants were familiarized with a three-dimensional object--a doll. Following familiarization, three novelty tests were…

This study compares interactions between infants and parents to interactions between infants and strangers. Infants from 2 weeks to 6 months of age were taped in face-to-face interactions with unfamiliar male and female adults. Tapes of parent-infant interactions were available from a prior study. Specific infant and adult behaviors were coded and…

An experiment was performed to show that infants perceive auditory and visual stimuli within a common space and that they perceive the sound as an attribute of the visual object. Subjects were 22 infants aged 3 to 5 months. Each infant was presented with a toy that moved in a small arc from side to side of a small window at the rate of one arc per…

This study investigated the effects of prior experience with contingent or noncontingent stimulation of infants' ability to learn different responses to control perceptual stimulation. In the pretest phase, baseline rates of level movement, panel press and vocal responding were determined for each of the twelve, 6-month-old infants in the study.…

This study measured infant responses to mother and stranger as a function of mother and stranger distance. A group of 10-month-old infants were pretested for level of object permanence and person permanence, and 18 males and 18 females were chosen as study participants. The infants were randomly assigned to one of three treatment groups: (1)…
