A central theme of research on human development and psychopathology is whether a therapeutic intervention or a turning-point event, such as a family break-up, alters the trajectory of the behavior under study. This article describes and applies a method for using observational longitudinal data to make more transparent causal inferences about the…

Multiple methods are vital to understanding development as a dynamic, transactional process. This article focuses on the ways in which quantitative and qualitative methodologies can be combined to enrich developmental science and the study of human development, focusing on the practical questions of "when" and "how." Research situations that may…

A total of 23 infants were longitudinally studied to ascertain how kind and amount of prereaching activity changes with age during the first four months of life. Substantial changes were observed in the pattern of prereaching around two months of age. (RH)

Provides an overview of research on infant and child emotion regulation, beginning with consideration of emotion as a set of responses to particular stimuli. Emotion regulation is the process through which activation in one response domain serves to alter, titrate, or modulate activation in another response domain. (RH)

To investigate sensory dominance in early development, a series of studies examined six-month-old infants' processing of multisensory stimulus compounds. Findings indicated that infants discriminated changes in the temporal characteristics of the auditory component but not in the visual component. This and other findings suggested that auditory…

Involving 10-month-old infants, a series of studies examined responses to temporally modulated compound auditory-visual stimuli. Findings indicated that, although the auditory modality can dominate the visual modality at 10 months of age, the visual modality can process temporal information when the temporal relationship of the information in the…

Criteria for defining event-frequency encoding as automatic were assessed in two experiments involving young children, college students, elderly, and mentally retarded persons. The first experiment used an online word-frequency task; the second used a study-test method with pictures as stimuli. (PCB)

Findings highlight the importance of development-related control efforts and beliefs for achieving a subjectively favorable balance of developmental gains and losses and for maintaining an optimistic perspective in middle and later adulthood. Results are discussed with reference to a theoretical model of development-related control activities. (RH)

Over 600 White females between 10.5 and 18.5 years of age were studied to test construct comparability across adolescence. Assessed were emotional functioning, eating problems, self-reflection, self-image, and mastery/adjustment to examine meaning equivalence in self-concepts and developmental psychopathology. Results suggest that the five factors…

The influence of three variables on response to undecidability was studied: (1) dual- versus single-solution rules; (2) nature of the choice contrast, and (3) presence or absence of additional information to resolve the undecidability. Participants were college students and third, fourth, and fifth grade elementary school students. (RH)

Experiment 1 examined the position that mirror-image confusions reflect an inability among three- to five-year-olds to determine whether their performance level differences reflect differences among nonreaders already attending and those not yet attending to reading cues. Experiment 2 examined the Experiment 1 four- and five-year-olds, identified…

Examines associations among contemporaneous measures of marital quality, parenting attitudes and behavior, and toddler development in two-parent families. Seventy-five families with one 20-month-old child served as subjects. Results generally indicated that good marital quality was associated with optimal toddler functioning and sensitive…

Focuses on: (1) principles that underlie regulation of distress and negative emotions among infants and young children; and (2) developmental trends that occur during the first years of life. Discusses the role of caregivers. Offers ideas that lend themselves to hypothesis testing and empirical validation. (RH)

Tested a two-step infant preventive intervention model. Subjects were 147 multiproblem mothers and their infants. Data partially supported the model. Additional analyses explored factors associated with individual differences in delivery of services and response to treatment. (RH)

Study examined how environmental and physical characteristics contribute to the emergence of adolescent girls' dating behavior. Subjects were girls who attend dance schools and girls who do not.
