Vocabulary

Absolute stability: Consistency in the level or amount of a personality attribute over time.
Active person–environment transactions: The interplay between individuals and their contextual circumstances that occurs whenever individuals play a key role in seeking out, selecting, or otherwise manipulating aspects of their environment.
Affect: Feelings that can be described in terms of two dimensions, the dimensions of arousal and valence (Figure 2). For example, high arousal positive states refer to excitement, elation, and enthusiasm. Low arousal positive states refer to calm, peacefulness, and relaxation. Whereas “actual affect” refers to the states that people actually feel, “ideal affect” refers to the states that people ideally want to feel.
Age effects: Differences in personality between groups of different ages that are related to maturation and development instead of birth cohort differences.
Agreeableness: A personality trait that reflects a person’s tendency to be compassionate, cooperative, warm, and caring to others. People low in agreeableness tend to be rude, hostile, and to pursue their own interests over those of others.
Anchoring: The bias to be affected by an initial anchor, even if the anchor is arbitrary, and to insufficiently adjust our judgments away from that anchor.
Attitude: A way of thinking or feeling about a target that is often reflected in a person’s behavior. Examples of attitude targets are individuals, concepts, and groups.

Independent self: A model or view of the self as distinct from others and as stable across different situations. The goal of the independent self is to express and assert the self, and to influence others.

Interdependent self: The tendency to define the self in terms of social contexts that guide behavior.
Interdependent self: A model or view of the self as connected to others and as changing in response to different situations. The goal of the interdependent self is to suppress personal preferences and desires, and to adjust to others. This model of self is prevalent in many collectivistic, East Asian contexts (e.g., China, Japan, Korea).
IQ: Short for “intelligence quotient.” This is a score, typically obtained from a widely used measure of intelligence that is meant to rank a person’s intellectual ability against that of others.
