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…

Very early precursors of disrupted social behaviours are significant to understanding the possibility of mitigating or changing behaviours through interventions. Spontaneous play situations between infant and parent in two groups of infants aged 8.5-9 months were observed. First, a large number of videos were analysed to develop an observational…

Infants' motor skill development triggers changes in parent-infant interactions, exploration, and play behaviors, particularly during periods of locomotor transitions. We investigated how these transitions reorganized infants' and mothers' explorations of spatial layouts. Thirteen infants and their mothers were followed biweekly from the age of 6…

Infants imitate others' individual actions, but do they also replicate others' joint activities? To examine whether observing joint action influences infants' initiation of joint action, forty-eight 18-month-old infants observed object demonstrations by 2 models acting together (joint action), 2 models acting individually (individual action), or 1…

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…

As part of a longitudinal study, infant/toddler pretend play development and maternal play modelling were investigated in dyadic context. A total of 21 children were videotaped in monthly play sessions with their mothers, from age 8 to 17 months. Child and mother pretend play frequencies and levels were measured using Brown's Pretend Play…

Thirty infants at 1;1 and their mothers were videotaped while playing for 18 minutes. Experimental stimuli were presented in three communicative intent contexts--proto-declarative, proto-imperative, and ambiguous--to elicit infant communicative bids that did and did not contain gestures. Mothers' responses were analyzed, and their verbal responses…

This research explored the nature of early childhood practitioners' interpretations of infants in their programs on the basis that such interpretations guide practitioner-infant interactions and curriculum decision-making processes. Twenty-four infant practitioners were asked to describe a nominated infant in their program and to interpret video…

This reflective essay describes the author's experiences as an observer in a behaviorist infant classroom. The author developed four categories of practice to describe what happened in the behaviorist infant room: (1) curricular focus on training typically developing infants to meet typical developmental milestones, (2) the use of highly…

This study analyzed the social interaction sequences and behavioral components of social interaction in two toddler playgroups across a 7-month period. Playgroup number 1 was composed of 6 male toddlers aged 1 year and playgroup number 2 was composed of 6 male toddlers aged 16 months. (JMB)

Examined sex differences in the play preferences of 2-year-old nursery school children and determined whether teachers of this age group reinforce female sex-typed behaviors as do teachers of older preschoolers. (SDH)

Considers contributions of Sigmund Freud and Rene Spitz to developmental psychology. Freud's contributions include his observations about play, perspectives on developmental processes, and ideas about unconscious mental activity. Spitz's contributions include his assessments of infants, perspectives on developmental processes, and his concept of…

This study examined the extent to which situational context differentially influences components of play. Two groups of play variables were distinguished: (1) style variables, (reflecting the overall tempo and diversity of play) and viewed as relatively sensitive indicators of short term reactions of situations; and (2) structural variables,…

Seventeen sets of opposite sex twins, 13 to 14 months old, were observed in a playroom situation with their mothers. Attachment behaviors, toy preference, style of play, and activity level were recorded. Analysis of four attachment behaviors indicated that girls looked at, vocalized to, and maintained proximity with their mothers significantly…

This document is comprised of the four issues in the second volume of a quarterly journal for parents of children in Montessori infant and toddler programs. The May 1998 issue contains an article on Treasure Baskets which are designed for non-mobile babies who can sit up, an article discussing the personal growth of a Montessori teacher who became…
