Differential Psychology Quiz

Individual Differences

• Psychology studies general rules of behavior, aiming to understand how most people behave.
• Differential psychology studies how people differ in thoughts, feelings, and behaviours, focusing on stable psychological traits, versus temporary psychological states.
• Differential psychology contrasts with cognitive psychology (examining why some have better memory than others) and social psychology (examining why some are less obedient than others). It also differs from developmental psychology (examining when people develop theory of mind) by investigating why individuals differ in these abilities.
• Ultimately, differential psychology analyzes how people differ in psychological traits, explores the reasons for these differences, and studies the impact on their lives.

What is Personality?

• Personality encompasses distinctive and relatively enduring patterns of thinking, feeling, and behaving.
• People's behaviors tend to be consistent over time and situations, reflecting lasting internal explanations for their actions. These patterns define personal identity.

Historical Perspectives on Personality:

A) Psychodynamic Perspectives (Freud)

• Freud's theory is the first formal personality theory. It aimed to treat patients with 'conversion hysteria", linking their symptoms to repressed trauma, often sexual or aggressive.

• The unconscious mind plays a crucial role in influencing behavior, as evidenced by symptom improvement after patients remembered traumatic events.

• Freud theorized personality as a system of interacting energies. Instinctual drives generate psychic energy that powers the mind.

• Three levels of mental processes exist:

• Conscious: current awareness

• Preconscious: unaware but retrievable

• Unconscious: beyond awareness

• Three interacting systems within personality:

• Id: The primal, unconscious part seeking immediate gratification (pleasure principle). It is present from birth.

• Ego: The rational, reality-testing component mediating between the demands of the id and superego. Operates primarily at a conscious level. This component develops by age 3.

• Superego: The moral component representing internalized societal and parental expectations. It develops by age 4/5.

• Behavior is driven by compromises among id's impulses, ego's control, and superego's moral demands.

• Anxiety or mental disorders arise from conflict between conscious and unconscious forces.

• Defense mechanisms are unconscious strategies to protect against anxiety. Key examples include repression (pushing anxiety-provoking thoughts into the unconscious), denial (refusing to acknowledge anxiety), and displacement (redirecting impulses to safer targets).

B) Psychosexual Stages of Development

• Freud posited that early childhood experiences shape adult personality.

• The id's pleasure-seeking tendencies focus on specific erogenous zones during distinct stages.

• Fixation, or an inability to progress through a stage, could lead to particular personality characteristics in adulthood. Adverse circumstances can lead to regression to easier stages.

• Key stages include:

• Oral (infancy): Pleasure seeking through sucking and swallowing.

• Anal (1-2 years): Pleasure from bowel and bladder elimination.

• Phallic (4-5 years): Pleasure from genitalia focused on resolving Oedipus/Electra complex (boys' desire for mothers and rivalry with fathers/girls' recognition of lack of penis).

• Genital (adolescence onwards): Mature sexual expression and relationships.

• Limitations:

• Controversial emphasis on sexuality in early childhood.

• Difficulty in empirically testing concepts due to abstract and subjective nature.

• Limited consideration of social and cultural factors, bias toward certain gender and cultural experiences.

B) Phenomenological-Humanistic Perspectives

• This perspective emphasizes conscious experience, self-perception, and personal responsibility for behavior.

• Phenomenology aims to understand how individuals experience the world in their present moment.

• Humanism views people as inherently good and driven to self-actualize.

• Rogers' theory features the self-concept, an enduring, organised view of ourselves guiding our thoughts and actions.

• Self-consistency is maintained by aligning self-perceptions and experiences. Incongruence (discrepancy between self-perception and experience) can lead to maladjustment.

• Limitations:

• Reliance on self-reports can be subjective and difficult to objectively measure.

• Self-actualization is complex and challenging to quantify.

Trait Theories of Personality

• Trait theories define personality in terms of the degree to which individuals possess certain characteristic traits, broadly encompassing cognitive, emotional, and behavioral dimensions. This fosters individual uniqueness and identity.
• Key approaches include factor analytical approaches (e.g., Cattell’s 16 personality factors, Eysenck's Extraversion-Stability model). The Five Factor Model (FFM) is the predominant model (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism).

Biological Foundations of Personality

• Twin studies suggest a significant genetic influence on personality differences. Heritability estimates for many traits are typically around 40-50%.
• Environment encompasses everything that's not genetic.

Culture and Gender in Personality

• Cultural factors significantly influence personality, affecting perceptions, interactions, and behaviour. Individualistic cultures emphasize individual choice, whereas collectivist cultures prioritize group goals.
• Research indicates varying levels of agreement across differing cultures on personality traits; some (like conscientiousness, extraversion, and agreeableness) show broad consistency, while others (neuroticism, openness) exhibit less universal agreement.
• Gender differences in personality exist and accord generally with stereotypes. Women tend to score higher on neuroticism and agreeableness than men, whilst men exhibit higher levels of assertiveness and excitement seeking.

Personality Assessment

• Various methods exist, including interviews, behavioral observations, and personality scales.
• Personality scales offer standardized questions to assess traits for large samples, but can be limited by participant honesty and self-report biases.
