Developmental Psychology
Introduction
Developmental Psychology is the discipline that seeks to identify and justify the changes (in behaviour) that individuals undergo throughout the lifespan (from the moment of conception until they die)
introduction Issues in Developmental Research:
* Sampling bias (representative sample)
* reviewer effects (mother/teacher/researcher)
* Selective attrition (problem in longitudinal studies)
* Practice effects (repeated measures influence performance)
* Validity/reliability of tests (tests of children special adult tests)
Research Designs
1. Cross Sectional: contrary subjects atomic number 18 studied at distinct ages
* Main advantage is that information can be bring ined over a vast age range in a short sequence
* so far this approach yields no information about past determinants of the age-related changes or about individual development
* Problem of cohort variation each age group was born in a different year and therefore has experienced different environmental influences
2.
longitudinal: same subjects at a variety of ages as they develop
* Problems: time and cost, subject loss (selective attrition), cross-generation data (how relevant is our early data), inflexibility (stuck with the sample and with the measure we initially decided upon)
Formulate hypothesis select research method and design study collect data analyse data and draw conclusions report findings
exhibit theories: dis tenaciousness in development Stage represent periods when there is qualitative change
Learning theories: changes are quantitative rather than qualitative continuity in development
Developmental Theories
Normative-Descriptive Approach: involves description of the normal or average status of children on specified characteristics at different age levels maturational theory
Gesells maturational theory
* Development is intrinsically guided (predeterministic), stressed precise observations to...If you want to get a full essay, order it on our website: Ordercustompaper.com
