Introduction to Personality Research

Flashcards covering the introductory lecture on personality research, theoretical perspectives, conceptual debates, data collection types (LOTS), ethics, and evaluation criteria.

According to Fritz Heider, what is "common sense psychology"?

The intuitive, everyday psychological knowledge that people naturally possess to evaluate and predict others' behaviour without having formally studied psychology.

What three key characteristics distinguish a scientific personality theory from intuitive common sense knowledge?

Scientific theories must be based on systematic scientific observations of large numbers of people, formulated in a systematic and coherent structure, and testable so they can be falsified.

What methodological limitation is noted regarding the observational basis of Sigmund Freud's personality theory?

Freud based his theory on a very small, non-representative sample consisting solely of women seen in a specific clinical setting.

Why is personality psychology considered unique among the different subfields of psychology?

It is the only field within psychology that studies the whole person by integrating cognitive, developmental, social, biological, and clinical psychology.

What is sociologist Erving Goffman's dramaturgical perspective on personality?

He argued that people do not have a single fixed personality; rather, the social world is like a theatre where individuals adopt different roles and behave according to the situational context.

What three fundamental questions must any comprehensive personality theory address?

What are people's characteristics (classifications), how did they become that way (development and causes), and why does a person behave the way they do (motives and mechanisms)?

How does the trait perspective approach the relationship between the "what" and the "why" of behaviour?

Trait theorists treat the "what" as the "why," meaning that a person acts in a certain way simply because they possess that trait (e.g., behaving in an extroverted manner because one is an extrovert).

How do the trait, social-cognitive, and psychodynamic perspectives differ in explaining why a mother behaves in an overprotective manner?

The trait perspective attributes it to her inherent affectionate nature, the social-cognitive perspective views it as learned behaviour to match peers (like wanting to be as good as a neighbour), and the psychodynamic perspective views it as an unconscious reaction to compensate for hidden resentment toward the child.

What three common philosophical conceptualizations of human nature do personality theorists adopt?

Viewing humans as rational actors who weigh pros and cons, as animals driven by instincts that must be controlled, or as information processors operating like computers.

How have external scientific and technological shifts historically influenced psychological theories of personality?

Psychology often adopts analogies from prominent contemporaneous developments, such as using the periodic table to inspire personality taxonomies, or using computer hardware, operating systems, and disks to conceptualize mental architecture.

Which theorists anchor the extreme internal and extreme external ends regarding the determinants of behaviour?

Sigmund Freud represents the extreme internal end (behaviour driven by internal unconscious forces), while B. F. Skinner represents the extreme external end (behaviour driven entirely by external rewards and punishments).

Where do trait theory and the social-cognitive perspective fall along the internal-external continuum of behavioural determinants?

Trait theory sits closer to the internal side because it attributes behaviour to innate biological and nervous system differences, whereas the social-cognitive perspective is closer to the external side because behaviour is learned from the environment, though mediated by cognitive processing.

How do trait theorists and psychoanalytic theorists differ when interpreting an individual who is friendly to female supervisors but unfriendly to male supervisors?

Trait theorists classify the behaviour as an inconsistency in the trait of friendliness, whereas psychoanalytic theorists view it as a consistent behavioural pattern driven by past experiences with a father figure.

According to Walter Mischel (1968) from the social-cognitive perspective, how can an individual who acts differently over a ten-year span still be considered consistent?

They are considered consistently good at adapting their behaviour flexibly to meet the demands of new situations.

What two explanations are offered for how humans maintain a unified sense of self, and what is the issue with the second?

Either multiple mental components operate as a complex interconnected system, or a central "self" acts as glue encoding all experiences; the issue with the latter is the homunculus problem of identifying where that self physically or conceptually resides.

How do Freud and Bandura differ regarding whether a prospective student will decide to study medicine?

Freud argues the past drives behaviour (unconscious avoidance rooted in negative childhood school experiences), whereas Bandura argues future expectations drive behaviour (high self-efficacy and belief in overcoming anxiety to reach future goals).

How does the humanistic perspective contrast with reductionist approaches in the science of personality?

Reductionism breaks a person down into isolated components (akin to analyzing isolated square tiles of a Chuck Close portrait), whereas the humanistic perspective views the individual holistically in context, including their hopes, past, present, and consciousness.

What does each letter in the acronym LOTS stand for regarding personality data types?

L stands for Life data, O stands for Observation data, T stands for Test data, and S stands for Self-report data.

What is Life data (L-data) in personality research, and what are typical examples?

Objective information obtainable from archival or public records without directly testing the participant, such as academic grades, criminal records, and marital status.

What is Observation data (O-data) in personality research?

Behavioural counts or trait rating scales completed by knowledgeable informants who know the individual, such as parents, teachers, or friends.

What is Test data (T-data) in personality research?

Standardized objective task or assessment scores with known population norms, such as IQ tests or the delay of gratification test.

Why is Self-report data (S-data) both the most widely used and vulnerable form of personality data?

It is direct and easily accessible for measuring subjective self-perceptions, but it is vulnerable to memory distortions, dishonesty, and social desirability bias.

What major ethical dilemmas arise from collecting and utilizing personality assessment data?

Whether researchers must disclose results to participants, how to manage the unexpected discovery of a personality disorder, and the fairness of using personality tests for hiring or firing when labels can become self-fulfilling prophecies.

What are the four primary criteria used to evaluate the quality of a personality theory?

1. Comprehensiveness (addresses what, how, and why).

2. Parsimony (explains multiple phenomena using minimal principles).

3. Falsifiability (generates testable hypotheses).

4. Reliability and validity of its assessment measures.

How does the historical transition depicted in this diagram illustrate the concept of parsimony in scientific theories?

The geocentric model required clumsy, complex assumptions like planetary epicycles, whereas the heliocentric model explained the same planetary motions by simply placing the sun at the center, demonstrating economy and parsimony.

Why is falsifiability in personality research illustrated by the metaphor of looking for a "black swan"?

No number of observations of white swans can definitively confirm that all swans are white, so scientific inquiry must actively seek out the single counterexample (the black swan) that can prove a theory false.

What three levels of Bloom's Taxonomy are emphasized as learning outcomes in this personality study block?

Remembering (describing perspectives), comparing and contrasting (analyzing similarities and differences), and evaluating (forming evidence-based value judgments).
