  • Longitudinal Design
    A study approach where the same individuals are repeatedly assessed over months, years, or decades.
  • Cross-Sectional Design
    A method comparing different age groups at a single time point to examine developmental differences.
  • Individual Development
    Unique patterns of change and stability observed within a single person over time.
  • Temporal Precedence
    The ability to determine that one variable occurs before another, strengthening causal inferences.
  • Attrition
    Loss of participants from a study over time, potentially impacting data quality and sample representativeness.
  • Sampling Bias
    A distortion in study results caused by non-random participant selection or dropout.
  • Convenience Sample
    A group of participants who remain in a study due to motivation or availability, possibly reducing generalizability.
  • Developmental Psychology
    A field focused on understanding how humans grow, change, and develop throughout life.
  • Causal Relationship
    A connection where one variable directly influences another, though not always proven in developmental studies.
  • Research Validity
    The degree to which study findings accurately reflect the phenomena being investigated.
  • Experimental Design
    A research structure that can establish cause-and-effect by manipulating variables and controlling conditions.
  • Moral Problem Solving
    Tasks or assessments used to evaluate ethical reasoning and decision-making in participants.
  • Data Collection
    The process of gathering information from participants at specific time points or age groups.
  • Generalizability
    The extent to which study results apply to broader populations beyond the sample studied.
