Document Summary

Conceptual issues: personality development stability, coherence and change. Personality development-can be defined as the continuities, consistencies and stabilities in people over time and the ways in which people change over time. Rank order stability-is the maintenance of individual position within a group. Mean level stability-is the average level of a trait in group over time. Personality coherence-is maintaining rank order in relation to others but changing the manifestation of the trait. Personality change-is something that is internal to the person and is enduring over time. Population level-personality development that deals with the changes and constancies that apply to more or less everyone. Group differences level-are changes over time that different groups of people differently. Individual differences level-looks at how personality development effects each person. Stability of temperament during infancy- most personality studies that involve infants study temperament. They found that stable individual differences appear to emerge very early in life.
