    Study Notes

    Why Study Developmental Psychology?

    • Developmental psychology explores universal experiences with significant heterogeneity
    • Individual differences in people's lives provide insights into decision-making
    • It helps determine if a child's development is normal or needs professional intervention
    • Understanding optimal parenting practices and timelines, including when and how interventions like "time-outs" are effective
    • Identifying appropriate interventions for different children accounting for their individual tendencies and behaviors is crucial

    Developmental Methodology

    • Universal lunch programs provide healthy meals for all children
    • Studies of eyewitness testimony, like the Loftus research, examine how children respond to questioning, including the effect of specific tactics
    • Observing children's responses in structured games can reveal how accounts vary based on how questions are asked, and how interviewers' phrasing influences responses
    • Children often leave out key information, which isn't necessarily intentional, but dependent on how the information is elicited.

    Enduring Themes

    • Nature versus nurture is a key area of study with specific questions on their relative contributions, considering the interaction between genes and environments
    • Understanding the influence of genetics and environment on child development is fundamental to this field
