Define personality as psychologists use the term. Explain how personality differs from a temporary mood state.
Focus on stability, consistency, and individual differences.
Personality refers to relatively enduring patterns of thinking, feeling, motivation, and behavior that distinguish one person from another. A temporary mood state is shorter lasting and more situation-dependent, while personality describes stable tendencies that can appear across many contexts. - 2
A researcher finds that a person scores high in conscientiousness on a Big Five inventory. Predict two behaviors this person is more likely to show and explain why the prediction is probabilistic rather than certain.
A person high in conscientiousness is more likely to plan ahead, meet deadlines, keep materials organized, and persist toward goals. The prediction is probabilistic because traits describe tendencies, not guarantees, and behavior is also influenced by the situation, motivation, culture, and current stressors. - 3
Compare the Big Five trait model with Eysenck's PEN model. Identify one similarity and one difference.
Think about the number of traits and the theoretical goals of each model.
Both models describe personality using broad trait dimensions and assume that traits can be measured reliably. A key difference is that the Big Five includes openness, conscientiousness, extraversion, agreeableness, and neuroticism, while Eysenck's PEN model focuses on psychoticism, extraversion, and neuroticism and places stronger emphasis on biological bases of those dimensions. - 4
A student argues, 'If personality traits are stable, people should act the same way in every situation.' Explain why this statement oversimplifies the person-situation interaction.
The statement oversimplifies personality because traits influence patterns of behavior across time and situations, but they do not require identical behavior in every setting. Situational cues, social roles, incentives, and constraints can change behavior, while traits still help predict average tendencies and patterns across many observations. - 5
Use Freud's structural model to explain how the id, ego, and superego might each contribute to a person's decision to cheat on an exam or refuse to cheat.
Connect each structure to desire, morality, or realistic decision-making.
The id might push for cheating because it seeks immediate reward, such as a better grade with less effort. The superego might create guilt or moral pressure against cheating because it represents internalized standards. The ego would attempt to manage the conflict by considering reality, consequences, and possible choices, such as studying more or accepting a lower grade. - 6
Identify the defense mechanism in this example and explain your reasoning: After receiving harsh criticism from a supervisor, an employee goes home and yells at a roommate over a minor issue.
The defense mechanism is displacement. The employee redirects anger from the supervisor, who may feel unsafe or inappropriate to confront, toward the roommate, who is a less threatening target. - 7
A graph shows three people across five stressful events. Person A stays emotionally steady, Person B shows moderate distress that quickly returns to baseline, and Person C shows intense distress that remains high. Interpret the graph using the concepts of trait neuroticism and resilience.
Separate emotional reactivity from recovery after stress.
Person A appears low in trait neuroticism or high in emotional stability because their distress changes little across stressful events. Person B may show normal stress reactivity combined with resilience because they recover quickly. Person C may be higher in neuroticism or lower in resilience because their distress is intense and remains elevated over time. - 8
Explain how Bandura's concept of reciprocal determinism applies to personality development. Include the three interacting factors.
The three factors are personal factors, behavior, and environment.
Reciprocal determinism means that personality develops through ongoing interaction among personal factors, behavior, and the environment. For example, a student's belief that they are socially skilled may lead them to start conversations, those conversations may create positive social feedback, and that feedback may strengthen the student's social confidence. - 9
A personality inventory has high test-retest reliability but poor predictive validity for job performance. Explain what this means and why both reliability and validity matter.
High test-retest reliability means people tend to receive similar scores when they take the inventory at different times. Poor predictive validity means the scores do not accurately forecast job performance. Both matter because a test must measure consistently, but consistency alone is not enough if the test does not measure or predict what it is intended to measure or predict. - 10
Describe one advantage and one limitation of using self-report questionnaires to assess personality.
Consider both practicality and response bias.
One advantage of self-report questionnaires is that they can efficiently measure a person's own thoughts, feelings, and typical behaviors across many items. One limitation is that responses can be distorted by social desirability, lack of self-insight, careless responding, or misunderstanding of the questions. - 11
A scatterplot shows a correlation of r = .55 between conscientiousness and college GPA. Interpret this result without overstating causation.
A correlation of r = .55 indicates a moderate to strong positive relationship, meaning students with higher conscientiousness tend to have higher GPAs. This result does not prove that conscientiousness directly causes higher GPA because other variables, such as prior preparation, study environment, or motivation, may also contribute. - 12
Explain how a behavior geneticist might use twin studies to estimate the heritability of personality traits. Include a caution about interpreting heritability.
Heritability is about variation in a population, not destiny for a single person.
A behavior geneticist can compare personality similarity between identical twins, who share nearly all their genes, and fraternal twins, who share about half of their segregating genes. If identical twins are more similar than fraternal twins, genetic influence is suggested. Heritability should be interpreted cautiously because it applies to variation within a population and environment, not to whether a trait is fixed or unchangeable in an individual. - 13
Compare humanistic and psychodynamic approaches to personality. Include how each approach views motivation.
Humanistic approaches emphasize conscious experience, personal growth, free choice, and the drive toward self-actualization. Psychodynamic approaches emphasize unconscious conflicts, early experiences, and internal forces that shape behavior. In motivation, humanistic theory focuses on growth and meaning, while psychodynamic theory often focuses on managing conflict, anxiety, and unconscious desires. - 14
A client has a large gap between their real self and ideal self and reports chronic dissatisfaction. Explain this pattern using Carl Rogers's theory.
Use the term incongruence and connect it to self-concept.
In Rogers's theory, a large gap between the real self and ideal self is called incongruence. Incongruence can produce anxiety, defensiveness, and dissatisfaction because the person's actual experience does not match the person they believe they should be. Greater congruence and unconditional positive regard can support healthier self-development. - 15
Design a brief study to test whether extraversion predicts leadership emergence in student project groups. Identify the independent or predictor variable, the outcome variable, and one control variable.
A study could measure students' extraversion with a validated Big Five questionnaire before group projects begin, then have peers rate who emerged as a leader after the project. The predictor variable would be extraversion, the outcome variable would be leadership emergence, and one control variable could be prior leadership experience, group size, gender, or academic performance. The design would test prediction but would need additional controls or experimental methods to support causal claims.
