Moll, Henrike; Tomasello, Michael – Developmental Science, 2004
Infants follow the gaze direction of others from the middle of the first year of life. In attempting to determine how infants understand the looking behavior of adults, a number of recent studies have blocked the adult's line of sight in some way (e.g. with a blindfold or with a barrier). In contrast, in the current studies an adult looked behind…

Rogers-Warren, Ann K.; And Others – 1985
Changes in mothers' strategies for eliciting verbal responses (EVR's) as a function of child age were investigated in this study. Seven mother-child dyads were observed in their homes when the children were 16, 21, 24, 30, and 34 months of age. Mother EVR's were coded according to syntactic form, type of cue for child response, and complexity of…

Stimson, Carol A.; And Others – Child Study Journal, 1997
In this longitudinal study, 60 mothers rated their toddler's personality traits concerning social relations and exploration of the physical and social world. Data showed that mothers of toddlers from older cohorts were more likely to have stable and consistent, but not more negative, perceptions of their child's personality over six months than…

Vaughn, Brian E.; And Others – Developmental Psychology, 1992
Assessed temperament of children of 5-42 months of age. A Q-sort measure was used to assess children's attachment security between 12 and 45 months. Analysis of results revealed an association between temperament and attachment security at all ages. (BC)

Bremner, J. Gavin; And Others – Journal of Experimental Child Psychology, 1994
Tested children 18 months to 4 years for their ability to relocate a hidden object after self-produced movement around an array of 4 locations. Children encountered no specific difficulty in coordinating dimensions, or they solved the task without recourse to such a system. They also appeared to change strategy when the problem requires more…

Goodell, Elizabeth W.; Studdert-Kennedy, Michael – Journal of Speech and Hearing Research, 1993
This study examined whether toddlers build a repertoire of words as integral sequences of gestures and then differentiate these sequences into their gestural and segmental components. Results demonstrate clear differences in duration and coordination of gestures between children and adults and a shift toward the patterns of adult speakers during…

Jessee, Peggy O.; And Others – Early Child Development and Care, 1994
Investigated young children's social interactions with a baby in a group care setting. Observations of young children as they responded to an infant revealed differences in comforting, sharing, and cooperation according to age and sex. Also, toddlers' social interactions with the infant increased after the infant reached 18 months of age, and…

Crnic, Keith; Booth, Cathryn L. – Journal of Marriage and the Family, 1991
Assessed daily hassles of parenting in parents of children aged 9-12, 18-24, and 30-36 months. Reported hassles were significantly greater with increasing child age; mothers and fathers did not differ in amount of hassle perceived. Perceptions of hassles were related to indices of support and social cognition. Parental social support moderated…

Troseth, Georgene L.; DeLoache, Judy S. – Child Development, 1998
Examined whether toddlers would use information presented through video to solve a retrieval problem. Found that 2.5-year-olds were very successful at finding a hidden toy based on viewing a televised hiding event, but 2-year-olds were not. Substantially better performance was achieved by other 2-year-olds who either watched or believed they were…

Ahnert, Lieselotte; Rickert, Heike; Lamb, Michael E. – Developmental Psychology, 2000
Described experiences of 84 German toddlers enrolled or not enrolled in child care. Found total amount of care per weekday did not differ by child-care status; child-care toddlers received lower care levels from center providers; their mothers engaged in more social interactions during nonworking hours than did mothers of home-only toddlers; and…

Chen, Zhe; Siegler, Robert S. – Monographs of the Society for Research in Child Development, 2000
Analyzed 1.5- and 2.5-year-olds' problem solving and learning. Found that changes in toddlers' strategies could be assessed reliably on a trial-by-trial basis, that changes followed the basic form predicted by the overlapping waves model, and that analyses could reveal information about the qualitative and quantitative aspects of their learning.…

Naigles, Letitia R.; Bavin, Edith L.; Smith, Melissa A. – Developmental Science, 2005
Toddlers' (MA = 22 and 27 months) ability to extend newly taught verbs to new situational and sentential contexts was investigated. Children were interactively taught two novel verbs, presented in only the transitive frame (e.g. "You're lorping the ball"), in a playroom setting. They then viewed the verb actions presented on side-by-side monitors…
