The analysis of cross-lagged relationships is a popular approach in prevention research to explore the dynamics between constructs over time. However, a limitation of commonly used cross-lagged models is the requirement of equally spaced measurement occasions that prevents the usage of flexible longitudinal designs and complicates cross-study…

Eye-tracking research on social attention in infants and toddlers has included heterogeneous stimuli and analysis techniques. This allows measurement of looking to inner facial features under diverse conditions but restricts across-study comparisons. Eye-mouth index (EMI) is a measure of relative preference for looking to the eyes or mouth,…

The present study considered multiple aspects of sleep in a community sample of young children (at ages 30, 36, and 42 months) and their mothers, using both diaries and actigraphy. Through principal components analysis, 17 of 20 commonly used actigraphy variables were reduced to four main components whose variables formed composites of: Activity,…

Little is known about whether a widely used mindfulness measure in adults--the Five Facet Mindfulness Questionnaire (FFMQ)--is also reliable and valid in adolescents. The current study evaluated the psychometric properties of a 20-item short-form FFMQ in a sample of 599 high school students (M[subscript age] = 16.3 years; 49% female) living in the…

Previous studies used chronological age to examine the relationship between aging and volunteerism. In the current study, we examined the influence of subjective life expectancy (SLE) on volunteering based on the socioemotional selectivity theory emphasizing that older adults focus on very close relationships. Data of 11,203 older adults, 55 to 74…

Researchers are often interested in studying how the timing of a specific event affects concurrent and future development. When faced with such research questions there are multiple statistical models to consider and those models are the focus of this paper as well as their theoretical underpinnings and assumptions regarding the nature of the…

The goal of the present study is to examine the stability of time attitudes profiles across a one-year period as well as the association between time attitudes profiles and several variables. These variables include attitudes towards alcohol, context of alcohol use, consumption of a full drink, and subjective life expectancy. We assessed the…

This study investigated whether the amount and timing of group-based childcare between birth and 51 months were predictive of cognitive development at 51 months, taking into account other non-parental childcare, demographic characteristics, cognitive development at 18 months, sensitive parenting and a stimulating home environment. Children's…

"Why do parents parent the way they do?" remains an important question since it concerns both scientific issues, such as the stability or change of childrearing behavior, and clinical issues, such as the way to promote positive parenting in evidence-based programs. Using an accelerated design, the aim of this study was to examine several parental…

Parenting behaviors during times when young children may feel vulnerable, such as when encountering novelty, undoubtedly affect how children learn to regulate their reactions to these events. Theory suggests and some research supports the link between protective behavior--behaviors that shield the child from a potential threat--and regulation of…

Pregnancy and early motherhood involve uncertainty and change, which can evoke mental health problems. We identified maternal mental health trajectories in pre- and postnatal period, and examined their association with later child mental health and development. Finnish mothers reported psychological distress (General Health Questionnaire [GHQ-36])…

Summarizes recent trends in French developmental psychology, including those regarding (1) cognitive development as it relates to Piaget's theory, (2) psycholinguistics in preschool children, (3) social interaction, and (4) the structuring of time and space by infants and toddlers. (Author/RH)

The role of partner familiarity in the organization, duration, and content of social pretend play was studied in a triadic situation involving two friends and a third familiar child. Findings showed that play between friends was longer and richer than play with the third partner and that girls spent nearly twice as much time in fantasy as boys.…

From a developmental point of view, examines whether children and adults confuse time and distance when they traverse a specified distance in a particular period of time. (RH)

The present study investigates the contribution of general processing resources as well as other more specific factors to the life-span development of sensorimotor synchronization and its component processes. Within a synchronization tapping paradigm, a group of 286 participants, 6 to 88 years of age, were asked to synchronize finger taps with…
