The impact of differences in maternal self-efficacy and infant difficulty on mothers' sensitivity to small changes in the fundamental frequency of an audiotaped infant's cry was explored in 2 experiments. The experiments share in common experimental manipulations of infant difficulty, a laboratory derived measure of maternal efficacy (low,…

The ability to form secure attachments during early childhood promotes a lifetime of emotional health. This article describes emotional milestones for babies (i.e., activities that promote self-comfort and self-control), as well as for toddlers. In the case of toddlers, a profound emotional milestone that is accomplished during the first year is…

This paper provides three representative examples that highlight the ways in which procedures can be combined to study interactions across traditional domains of study: segmentation, word learning, and grammar. The first section uses visual familiarization prior to the Headturn Preference Procedure to demonstrate that synchronized visual…

This paper is a response to a review of the conference titled, "Unintegration, Disintegration and Integration", written by Cathy Urwin and Maria Rhode in the ACP Bulletin. The review mentioned Michael Fordham, noting that he referred to a "good" kind of unintegration. In this paper, I point out that this is a somewhat misleading reference to what…

We assessed 19-month-olds' appreciation of the conventional nature of object labels versus desires. Infants played a finding game with an experimenter who stated her intention to find the referent of a novel word (word group), to find an object she wanted (desire group), or simply to look in a box (control group). A 2nd experimenter then…

The three articles in this issue of a periodical focussed on various aspects of the life and health of children in the tropics concern: (1) immune defenses; (2) interactions between nutrition disorders and infection; and (3) immunity and vaccination. The science of immunology has progressed rapidly in recent years. A brief review of present…

A theoretical position that mind is not separate from the ways in which it is evidenced through the body is in contrast with an assumption made in the literature on children's theory of mind that maintains that mental states can only be demonstrated independently of their behavioral context. This assumption is tested by the false belief criterion,…

This study examined the abilities of 10-month-old infants to detect correlations between objects and persons based on the characteristic of gender. A total of 32 infants were habituated to six stimuli in which a picture of a male or female face was paired with one of six objects such as a football or frying pan. Three objects were associated with…

The influence of the presence and novelty of an adult stranger on the reactions of 36 full-term year-old infants was investigated. Subjects were placed near their mothers in a room containing a new toy and either the same, a different, or no adult stranger for eight 4-minute trials. (Author/GO)

Twelve children were observed monthly between the ages of 1 and 2 1/2 to determine whether the situational features expressed by their single words were combined later in their two-word utterances. (JMB)

Reports an investigation of: (1) the ability of newborns to discriminate different sapid substances and different molar concentrations within those substances; and (2) the role of immediate prior sucking and ingestion experience in altering subsequent oral behavior. Taste discrimination is demonstrated; but taste preferences seem independent of…

An experiment with monochromatic lights is discussed in terms of the selective effects of wavelength on looking time and pleasantness, comparisons of infant and adult data, and differentiation of the selective effects of color category centers and color category boundaries. (JMB)

This study investigated the relationship between task difficulty and ability level as a factor in producing imitative behavior in infants. A total of 28 toddlers, ranging in age from 14 to 28 months, participated in the study. (Author/JMB)
