Mindfulness meditation interventions (MMIs) are formal training programs which utilize mindfulness techniques to improve attentional control and reduce stress and anxiety. Past investigations have shown that mindfulness-based interventions are effective in improving symptoms of anxiety and depression in both adolescents and adults, making this a promising natural approach to treating mood disorders. The current study sought to examine the neurophysiological effects of a 10-week MMI, in a relatively unexplored age-range (7–10 years). The non-clinical participants demonstrated increases in interhemispheric alpha coherence, as well as increased theta, alpha, and beta power particularly in frontal and central areas; reflecting a lower neurological risk for anxiety development. However, two common measures linked to anxiety, frontal and posterior alpha asymmetry remained largely unchanged following the training period. Still, these preliminary results exemplify the potentially positive effects of mindfulness meditation on preadolescents; this time on neurophysiological functioning.

The goal of developmental science is to describe and explain growth and change across time. There are challenges to doing this effectively during the prenatal period and in early infancy. Yet, it is imperative to examine the confluences of early experiences that occur during normative development as well as to identify factors associated with risk that may set the trajectory for future dysregulation in development. In this chapter, a review of the measures employed in fetal and infant developmental research is presented, including those that have been generated to assess infant temperament along with mother–infant affective and social interactive patterns. Moreover, physiological measures (i.e., electroencephalograms, EEG) that reveal notable brain and neuro-hormonal influences (i.e., cortisol and oxytocin) are discussed as they serve as potential biomarkers of future patterns of regulation and dysregulation. The benefits and limitations of behavioral and physiological measures for informing prenatal and infant development research are noted, including reliability and validity considerations. The overarching theme of this chapter is to inform the next generation of researchers as to the innovative designs in this field; to present relevant and meaningful methods for data collection and analysis; and to provide suggestions for future work that can serve to advance the field of fetus-to-infant developmental science.

This comprehensive guide offers a rich introduction to research methods, experimental design and data analysis techniques in developmental science, emphasizing the importance of an understanding of this area of psychology for any student or researcher interested in examining development across the lifespan. The expert contributors enhance the reader’s knowledge base, understanding of methods, and critical thinking skills in their area of study. They cover development from the prenatal period to adolescence and old age, and explore key topics including the history of developmental research, ethics, animal models, physiological measures, eye-tracking, and computational and robotics models. They accessibly explore research measures and design in topics including gender identity development, the influence of neighborhoods, mother-infant attachment relationships, peer relationships in childhood, prosocial and moral development patterns, developmental psychopathology and social policy, and the examination of memory across the lifespan. Each chapter ends with a summary of innovations in the field over the last ten years, giving students and interested researchers a thorough overview of the field and an idea of what more is to come. Conducting Research in Developmental Psychology is essential reading for upper-level undergraduate or graduate students seeking to understand a new area of developmental science, developmental psychology, and human development. It will also be of interest to junior researchers who would like to enhance their knowledge base in a particular area of developmental science, human development, education, biomedical science, or nursing.

There is renewed interest in person-centered approaches to understanding the structure of temperament. However, questions concerning temperament types are not frequently framed in a developmental context, especially during infancy. In addition, the most common person-centered techniques, cluster analysis (CA) and latent profile analysis (LPA), have not been compared with respect to derived temperament types. To address these gaps, we set out to identify temperament types for younger and older infants, comparing LPA and CA techniques. Multiple data sets (N = 1,356; 672 girls, 677 boys) with maternal ratings of infant temperament obtained using the Infant Behavior Questionnaire-Revised (Gartstein & Rothbart, 2003) were combined. All infants were between 3 and 12 months of age (M = 7.85; SD = 3.00). Due to rapid development in the first year of life, LPA and CA were performed separately for younger (n = 731; 3 to 8 months of age) and older (n = 625; 9 to 12 months of age) infants. Results supported 3-profile/cluster solutions as optimal for younger infants, and 5-profile/cluster solutions for the older subsample, indicating considerable differences between early/mid and late infancy. LPA and CA solutions produced relatively comparable types for younger and older infants. Results are discussed in the context of developmental changes unique to the end of the first year of life, which likely account for the present findings. (PsycINFO Database Record
