Psychoanalytic/Psychodynamic Perspective
Emphasizes the role of unconscious psychological processes, particularly early childhood experiences, in shaping personality and behavior.
Id
The unconscious part of personality that seeks immediate gratification of basic drives.
Ego
The rational part of personality that mediates between the id and the superego.
Superego
The part of personality that represents internalized ideals and provides standards for judgment.
Defense mechanisms
Unconscious strategies used by the ego to manage anxiety from unacceptable thoughts.
Unconscious
The part of the mind that contains thoughts, memories, and desires not in current awareness.
Psychodynamic therapies
Therapeutic approaches that focus on unconscious processes and past experiences.
Behavioral Perspective
Emphasizes observable behaviors and how they are learned through interactions with the environment, primarily via conditioning.
Classical conditioning
Learning through association of two stimuli to produce a new response.
Operant conditioning
Learning through consequences, where behavior is strengthened by reinforcement or weakened by punishment.
Shaping
Reinforcing successive approximations toward a desired behavior.
Incentive theory of motivation
Motivation driven by external rewards and goals.
Behavioral therapies
Treatments based on the principles of learning to change maladaptive behaviors.
Humanistic Perspective
Emphasizes the inherent goodness of people and their capacity for growth.
Self-actualization
The process of fulfilling one's potential and becoming the best version of oneself.
Unconditional positive regard
Acceptance and love from others regardless of behavior or mistakes.
Positive psychology
The scientific study of human strengths and well-being.
Self-determination theory of motivation
The theory that people are motivated by needs for autonomy, competence, and relatedness.
Client-centered therapies
Therapy emphasizing a supportive environment and unconditional positive regard.
Cognitive Perspective
Emphasizes internal mental processes like thinking, memory, and perception and how these influence behavior.
Encoding
the process of putting information into memory
Storage
the retention of encoded information over time
Retrieval
the process of getting information out of memory
Chunking
organizing information into manageable and familiar units
Schema
a mental framework used to organize and interpret information
Top-down processing
perception driven by cognition and prior knowledge
Bottom-up processing
perception based on sensory input
Heuristics
simple thinking strategies or rules of thumb used to solve problems efficiently
Confirmation bias
the tendency to search for information that supports one's beliefs
Hindsight bias
the tendency to believe, after an event has occurred, that it was predictable
Perceptual set
a mental predisposition to perceive one thing and not another
Framing
the way information is presented, which can affect decision-making
Stages of cognitive development
Piaget's theory describing how children's thinking evolves in stages
Cognitive appraisal
the interpretation of a situation that triggers stress or emotion
Stress
a negative emotional and physiological response to perceived threats
Distress
harmful or damaging stress
Eustress
positive, beneficial stress that can motivate and improve performance
Cognitive therapies
therapy that focuses on changing maladaptive thought patterns
Social-Cognitive Perspective
emphasizes that learning and behavior are shaped by a dynamic interplay between cognition, behavior, and the environment.
Social learning theory
learning through observing and imitating others
Observational learning
learning by watching others and modeling their behavior
Reciprocal determinism
the idea that behavior, environment, and cognition all influence each other
Locus of control
the degree to which people believe they control their own outcomes
Intrinsic motivation
motivation driven by internal rewards or personal satisfaction
Extrinsic motivation
motivation driven by external rewards or pressures
Normative social influence
conforming to be liked or accepted by a group
Informational social influence
conforming because one believes others have accurate information
Obedience
compliance with commands or instructions from an authority figure
Arousal theory of motivation
the idea that people are motivated to maintain an optimal level of arousal
Sensation-seeking
the tendency to pursue novel and intense experiences
Yerkes-Dodson law
of arousal performance is best at moderate levels of arousal
Self-efficacy
belief in one's ability to succeed in specific situations
Self-esteem
one's overall sense of self-worth or personal value
Deindividuation
loss of self-awareness in group situations that may lead to atypical behavior
Groupthink
faulty decision-making that occurs when group harmony overrides realistic appraisal
Group polarization
strengthening of a group's preexisting attitudes through discussion
Social loafing
the tendency for individuals to exert less effort in a group
Social facilitation
improved performance on simple tasks in the presence of others
Situational attribution
explaining behavior by situational factors
Dispositional attribution
explaining behavior by personality or traits
Resilience
the ability to recover from stress or adversity
Relative deprivation
feeling worse off by comparing oneself to others
Adaptation-level phenomenon
tendency to form judgments relative to a neutral level based on past experience
Cognitive-behavioral therapy
therapy combining cognitive restructuring with behavior modification
Biological Perspective
emphasizes the impact of the brain, genes, and other biological systems on behavior and mental processes.
Cerebellum
part of the brain that coordinates voluntary movement and balance
Long-term potentiation
a long-lasting increase in synaptic strength, believed to be the basis of learning and memory
Limbic system
brain structures involved in emotion, motivation, and memory
Amygdala
part of the limbic system involved in emotion, especially fear and aggression
Hippocampus
part of the limbic system involved in memory formation

brain region involved in decision-making, planning, and personality
Parietal lobes
brain region involved in processing sensory information
Occipital lobes
brain region involved in visual processing
Temporal lobes
brain region involved in auditory processing and language
