Study Notes

General Information

Labs involve exploring how variables influence each other while controlling for other factors.
Validity refers to the conclusion's strength, while reliability is its repeatability.
Test generalizability defines the boundaries of a test's validity.

Fundamental Psychological Needs

Competence involves feeling effective in one's environment.
Autonomy signifies having control and choice.
Relatedness highlights connections and care from others.

Flow

Flow is a state of exhilaration stemming from complex tasks and skills.
Characteristics include clear goals, feedback, appropriate challenges, and autotelic activities (valuable in themselves).
Flow leads to feeling in control and boosted self-esteem.

Correlation vs. Causation

Correlation describes the relationship between variables.
A positive correlation shows variables increasing together.
A negative correlation shows variables moving in opposite directions.

Experiment Design

Independent Variables (IV) are manipulated factors.
Dependent Variables (DV) are measured outcomes.
Controlled Variables (CV) are kept constant to isolate the effect of the IV.

Validating a New Personality Test

Approach 1: Evaluate the new test against an already validated test to identify correlations.
Approach 2: Correlate the new test with an established measure (should be above 0.8).
Internal Consistency (split-half correlation) is also essential. Cronbach's alpha measures average correlation.

Lab 2: Creativity

Creativity combines uniqueness and usefulness.
Divergent thinking involves 'outside-the-box' solutions.
Convergent thinking focuses on single best answers.
Examples include alternative use tests and incomplete figure tasks.
Remote Associates tasks link three words with a fourth.

Decision Making

Maximizing involves searching for the best possible choice.
Satisficing involves choosing a good enough option quickly.
Latent inhibition is the ability to block out unnecessary information. Useful for convergent thinking but not divergent.

Ebbinghaus Forgetting Curve

Memorized meaningless words to measure retention.
Significant memory loss even within a short period.

Recall vs Recognition

Recall involves retrieving information from memory.
Recognition involves identifying previously encountered information.

Studying Tips

Short, frequent study sessions are more effective than long ones.
Active recall (testing yourself) is better than highlighting.

Lab 3: Happiness

Sonja Lyubomirsky's research explores factors impacting happiness.
Set point (50%), intentional activity (40%), and circumstances (10%) are key factors.
The Social Readjustment Scale measures life stress.
The Relaxation response counteracts the stress response.

Psychophysics

Psychophysics examines how physical stimuli become psychological experiences.
Sensation is stimulation of sense organs.
Transduction is converting stimuli into electrical signals.
Perception is organizing and interpreting stimuli.

Fechner's Law & Signal Detection Theory

Fechner's law relates perceptual experience to the number of noticeable differences above the absolute threshold.
Signal detection theory combines sensory sensitivity and decision processes.
Concepts include hits, misses, false alarms, correct rejections.

Lab 5 (Illusions & Classical Conditioning)

Illusions showcase how perception distorts reality.
A perceptual set explains how prior expectations impact perception.
Experiments include studies on errors, progressive errors and random errors
Classical Conditioning experiments involve training a response using a stimulus.
Shaping behavior reinforces successive approximations of the desired response to accomplish a task.
Cumulative records track responses.
Extinction and spontaneous recovery refer to the loss and return of learned behaviors.
