A psychologist’s methods of measuring people’s personalities differ depending on the theory they believe the most strongly in 💭

Projective Tests

Projective tests include asking people to interpret vague, ambiguous stimuli that have more than one meaning. Test-takers reveal inner thoughts simply through their interpretation of the stimuli. There are two different types that you should be familiar with:

  • Rorschach inkblot test is where a psychologist shows people a series of inkblots and asks them to describe what they see. It is the most commonly used projective test, and they aren't really reliable.

  • The thematic apperception test (TAT) consists of a number of cards that each contain a picture of a person or people in a situation. These are also open to more than one interpretation and participants are asked to tell a story about it to reveal their inner thoughts.

Personality Inventories

Self-report inventories, or personality inventories, are questionnaires that ask people to provide information about themselves. There are so many different traits that could be gathered from these questionnaires, and psychologists created different versions of them.

One main personality inventory test you should know is the minnesota multiphasic personality inventory(MMPI). It is the most widely used self-report instrument that has lie detector questions built into the inventory to prevent deception and social desirability. It is used in just about any realm of personality and our everyday lives that you could think of.

Overview of Research Methods

Research MethodDescriptionPerspectives that use this methodBenefitsWeaknesses
Case studyIn-depth study of one individual.Psychoanalytic, humanisticLess expensive than other methods.May not generalize to the larger population.
SurveySystematic questioning of a random sample of the population.Trait, social-cognitive, positive psychologyResults tend to be reliable and can be generalized to the larger population.May be expensive; correlational findings.
Projective testsAmbiguous stimuli designed to trigger projection of inner dynamics.PsychodynamicDesigned to get beneath the conscious surface of a person's self-understanding; may be a good ice-breaker.Results have weak validity and reliability.
Personality inventoriesObjectively scored groups of questions designed to identify personality dispositionsTraitGenerally reliable and empirically validated. Explore limited number of traits.
ObservationStudying how individuals react in different situations.Social-cognitiveAllows researchers to study the effects of environmental factors on the way an individual's personality is expressed. Results may not apply to the larger population.
ExperimentationManipulate variables, with random assignment to conditions.Social-cognitiveDiscerns cause and effect.Some variables cannot feasibly or ethically be manipulated.
