A live video was used to study the development of visual self-recognition in a cross-sectional sample of 152 typically developing French children aged between 15 months to 6 years. Three reactions to a mark placed on the child's cheek without their knowledge were studied: the touch of the mark with their hand, the ocular responsiveness to the mark…

Since birth, infants develop the ability to perceive a wide range of intersensory relations among various kinds of amodal temporal information. This study addresses the development of the ability to perceive duration-based intersensory relations. Three groups of infants, four, seven and 10 months old, participated in two trials of an intersensory…

This study reports on the development of new motor and behavioural indicators for recognizing symbolic acts among infants. Following five infants between the ages of 6 and 18 months and their ability to use an object in novel way yielded four levels of action, based on the number of objects and actions combined in each symbolic act. Employing…

This qualitative multicase study explored the process through which three student caregivers engaged in relationships with key infants in the context of an infant practicum course as a foundation for learning about infant development and practice. Focusing on caregiver-infant dyads, data sources included videotaped observations of caregiver-child…

A microgenetic research design with a multiple case study method and a combination of quantitative and qualitative analyses was used to investigate interdyad differences in real-time dynamics and developmental change processes in mother-infant face-to-face communication over the first 3 months of life. Weekly observations of 24 mother-infant dyads…

Case study research methodology was used to describe the play behaviors of three infants at 12 months of age, who were later diagnosed with an autism spectrum disorder. Data included standardized test scores, and analyses of video footage of semi-structured play sessions from infants identified as high risk for autism, because of having a sibling…

This qualitative multi-case study explored the social exchanges and responsive connections between infants and their infant childcare teachers within a group care context. Infants' naturally occurring behaviours were videotaped purposefully at two separate time points, near the end of their first year and approximately six months later. Findings…

Infants with visual impairment often require additional interaction from adults to reinforce behaviors that lead to competency at mealtimes, but parental and professional confidence in teaching these skills is often limited. In the following collective case study, the authors, a speech/language pathologist (S/LP), occupational therapist (OT), and…

For every five healthy babies and infants, there is at least one who brings unusual stresses for its parents with behaviors such as inconsolable crying, sleep disorders, refusal to eat, chronic moodiness, incessant demands for attention, fearful clinging, or tantrums. Available for the first time in English, this influential German collection…

Preferential-looking studies suggest that by 2 months of age, infants may have knowledge about some object properties, such as solidity. Manual search studies of toddlers examining these same concepts, however, have failed to provide evidence for the same understanding. Investigators have recently attempted to reconcile this disparity but failed…

Contending that developmental disability is defined by cognitive and affective performance as well as hazardous biological events, the authors consider multiple factors as cumulative in placing an infant at risk for future developmental disability. A risk scoring system based on biological and behavioral factors in an additive manner is presented.…

Explores the recorded remarks of one infant female child related to children's books. Contrasts the "fantastic" statements spontaneously generated by the child with the ways in which she responded to animism and other "fantastic" conventions in picture books heard by her at the same ages. (HB)

A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a…

A case study of the period of repetitive babbling in one Dutch infant is reported. Repetitive babbling is seen as a systematic and continuous process, during which the child is applying certain strategies in order to form concepts concerning the possibilities of his or her articulatory apparatus. Strategies identified are: (1) variation…
