LI, Biology and Culture

LI, Biology and Culture. Life span development is a dynamic co-construction of biological and cultural processes occurring simultaneously within different time scales (microgenetic, ontogenetic, phylogenetic) and across different levels (neurobiological, cognitive, behavioral, sociocultural).

Presentation Transcript

  1. LI, Biology and Culture • Life span development is a dynamic co-construction of biological and cultural processes occurring simultaneously within different time scales (microgenetic, ontogenetic, phylogenetic) and across different levels (neurobiological, cognitive, behavioral, sociocultural).

  2. LI, Biology and Culture • Phylogenetic time: Culture affects genes (cultural change modifies long term biological natural selection process) • (ex. urban living and stress resistant genes).

  3. LI, Biology and Culture • Ontogenetic time: Culture affects social situational context (values, norms, language, etc. transmitted through social interaction), which affects individual ontogeny over the life span. • ex. infant sleep in industrial vs. traditional cultures.

  4. LI, Biology and Culture • Microgenetic time: Culture affects moment-to-moment activities & experience (genetic, neuronal, cognitive, behavioral) • ex. Asian children’s use of abacus enhances mental calculation; music training affects brain function.

  5. LI, Biology and Culture • Development involves feed-downward (culture-biology) and feed upward (biology-culture) interactive processes. • Plasticity exists at all levels and at all ages.

  6. QUINTANA ET AL.Race, Ethnicity, and Culture in Child Development • Introduction to special issue—focus was on: • Normative development in context • Intergroup relations and attitudes • Identity development

  7. QUINTANA ET AL. • Trends in research represented in special issue: • Distinguishing race/ethnicity and cultural effects • Distinguishing culture and immigration status effects • Finding proximal mediators of demographic effects • Focus on context (neighborhood, racial density, etc.) • Need to study normative development nonethnocentrically • Ethnic/racial identity—multidimensional and fluid • Acculturation/acculturation conflict • Intergroup relations/attitudes • Methodological advances: • Research-community collaboration • Measurement of ethnicity/race variables

  8. QUINTANA ET AL. • Challenges: • Theoretical: Need theory of context effects • Measurement: Need explicit, not proxy measures • Content: Much research to be done • Cultural validity: Sampling, constructs/measures, & analyses
