A total of 114 infants at three age levels (11, 18, and 28 weeks) were rated by their mothers on a termperament questionnaire and subjected to a habituation procedure. Results suggest that subject loss in habituation studies may be the result of nonrandom individual difference factors and not just the result of temporary fluctuations in state.…

This study of the stability of parent behaviors toward toddlers over a 3-week period used both aggregated and nonaggregated data. Comparison of stability correlations indicated higher stabilities for aggregated scores, with the level of stability increasing as scores from additional single sessions were aggregated. (PCB)

Discusses implications of a study of middle-class infants seen in the Ainsworth strange situation at 12.5 and 19.5 months; the investigation produced results inconsistent with the corpus of previous findings. (Author/RH)

Analyzes methods used to record infant head position and the limits of these methods. An experimental device is proposed which records infant head turning and head righting when the vestibular system is stimulated. (Author/DB)

Maintains that findings showing numerical computation abilities in infants are considerably more robust and consistent than Wakeley, Rivera, and Langer suggest. Asserts that all the interim replication attempts have successfully replicated Wynn's original findings. Discusses possible reasons for failure to replicate in Wakeley et al. experiments.…

This study investigated the common practice in infant research of eliminating from reported data large numbers of subjects who prove uncooperative (sleepy, fatigued, fussy) during the experiment. It was suggested that these excluded infants constitute a special class of subjects and that the inclusion of their data would greatly alter the research…

Asserts (1) that contrary to Waters, findings affirm the importance of viewing mother-infant attachment as a dynamic relationship, responsive to family conditions, and (2) that these findings are consistent with those of other researchers. (Author/RH)

Multiple discriminant function analysis was conducted with data from Strange Situations. Results enable researchers to obtain attachment classifications directly from scores on interactive behavior and crying during reunion episodes. (PCB)

The influence of maternal stimulation on infant exploratory behavior was examined in both a cross-sectional/ correlational study and an experimental study, in order to overcome the limitations on making causal claims that attend most research into maternal influence on infant development. (Author/DB)

Asserts that findings on whether young infants look longer at incorrect addition and subtraction have been inconsistent or negative. Hypothesizes that imprecise ordinal calculating with very small numbers of objects develops in late infancy and that precise calculating develops in early childhood. (Author/KB)

Examines 2,000 Strange Situation classifications obtained in eight different countries. Differences and similarities between distributions in classifications of samples are investigated using correspondence analysis. Substantial intracultural differences are established; data also suggest a pattern of cross-cultural differences. (Author/RWB)

Temperament and attachment, as defined by Bowlby and his followers, are fundamentally different constructs, and research guided by the attachment perspective cannot meaningfully be assimilated to the temperament construct. Qualitative aspects of relationships simply cannot be reduced to individual behavioral dimensions. (RH)

Reviews 26 instruments developed to assess temperament at the infant, preschool, and school-age levels, giving particular attention to instrument content, standardization samples, reliability, and validity. It is concluded that, at present, no single psychometrically adequate instrument is available. Suggestions are made for future approaches to…

This study of 105 12-month olds replicated 4 similar studies that showed that infants in day care are at risk for insecure attachment. Failure to reproduce significant results suggests that the research literature on infant day care and attachment may be biased by the unavailability of "file drawer" studies--unpublished data showing no…

Suggests that dominance can be defined as asymmetry in predictability in social variables of importance, and bidirectionality as symmetrical predictability. Procedures which address the concepts of cyclicity within a person and synchronicity between people and which assess asymmetry and symmetry in social interaction are discussed. (Author/RH)
