Psychology | The scientific study of thought and behavior |
Central Nervous System | The part of the nervous system that comprises the brain and the spinal cord |
Functional MRI | Brain imaging technique that uses magnetic fields to produce detailed images of activity in areas of the brain and other soft tissues |
Identical twins | Twins that develop from a single fertilized egg that splits into two independent cells |
Fraternal twins | Twins that develop from two different eggs fertilized by two different sperm |
Neurons | The cells that process and transmit information swag in the nervous system |
Neurotransmitters | Chemicals that transmit information between neurons |
Somatic Nervous System | Nerve cells of the peripheral nervous system that transmit sensory info to the central nervous system and those that transmit info from the CNS to the skeletal muscles |
Autonomic Nervous System | All the nerves of the peripheral nervous system that serve involuntary systems of the body, such as the internal organs and glands |
Peripheral nervous system | The part of the nervous system that comprises all the nerve cells in the body outside the central nervous system |
MRI | Brain imaging technique that uses magnetic fields to produce detailed images of the structure of the brains and other soft tissues |
EEG | A method for measuring brain activity in which the electrical activity of the brain is recorded from electrodes placed on a person's scalp |
Sympathetic Nervous System | Part of the autonomic nervous system that activates bodily systems in time of emergency (ex: increase heart rate, dilate pupils) |
Implicit memory | Kind if memory made up of knowledge based on previous experiences, such as skills that we perform automatically once we have mastered them; resides outside conscious awareness |
Explicit memory | Knowledge that consists of the conscious recall of facts and events |
Classical conditioning | Form of associative learning in which a neutral stimulus becomes associated with a stimulus to which one has an automatic response |
Operant conditioning | The process of changing behavior by manipulating the consequences of that behavior |
Social learning theory | A description of the kind of learning that occurs when we model or imitate the behavior of others |
Latent learning | Learning that occurs in the absence of reinforcement and is not demonstrated until later, when reinforcement occurs |
Extinction | The weakening and disappearance of a conditioned response in the absence of reinforcement |
Generalization | Extension of the association between unconditioned stimulus and conditioned stimulus to include a broad array of similar stimuli |
Modeling | The imitation of behaviors performed by others |
Primary reinforcers | Innate, unlearned reinforcers that satisfy biological needs (such as food, water, or SEX.) |
Secondary reinforcers | Learned by association, usually via classical conditioning (such as money, grades, and peer approval) |
Intelligence | A set of cognitive skills that include abstract thinking, reasoning, problem solving, and the ability to acquire knowledge |
Mental age | The equivalent chronological age a child has reached based on his/her performance on an IQ test |
G-Factor theory | Spearman's theory that intelligence is a single general (g) factor made up of specific components |
Multiple-factor theory of intelligence | Idea that intelligence consists of distinct dimensions and is not just single factor |
Validity | The degree to which a test accurately measures, such as intelligence, and not something else, and the degree to when it predicts real-world outcomes |
Reliability | Consistency if a measurement, I such as an intelligence test |
Id | The seat of impulse and desire; the part of our personality that we do not yet own; it owns or controls us- sole function is to seek pleasure |
Ego | A sense of self; the only part of the mind that is in direct contact with the outside world; makes a realistic attempt to obtain pleasure |
Superego | The part of self that monitors/controls behavior; stands over us and evaluates actions in terms of right and wrong; our conscious |
Personality | The unique and relatively enduring set of behaviors, feelings, thoughts, and motives that characterize an individual |
Bipolar disorder | Mood disorder characterized by substantial mood fluctuations, cycling between very low (depressive) and very high (manic) moods |
Dissociative disorders | Psychological disorders characterized by extreme splits or gaps in memory, identity, or consciousness |
Somatoform disorders | Psychological disorders that take bodily or physical form and mimic physical diseases, but haver no known physical cause or medical basis |
Schizophrenia | Psychotic disorder characterized by significant disturbances in thought and emotion, specifically problems with perception, including hallucinations |
Personality disorders | Patterns of cognition, emotion, and behavior that develop in late childhood or adolescence and are maladaptive and inflexible; they are more consistent than clinical disorders |
PTSD | A type of anxiety disorder triggered by exposure to a catastrophic or horrific event that poses serious harm or threat |
Behavior therapies | Therapies that apply the principles of classical and operant conditioning in the treatment of psychological disorders |
Cognitive-behavioral therapy | An approach to treating psychological disorders that combines techniques for restructuring irrational thoughts with operand and classical conditioning techniques to shape desirable behaviors |
Cognitive therapy | Any type of psychotherapy that works to restructure irrational thought patterns |
Group therapy | Therapeutic setting in which several people who share a common problem all meet regularly with a therapist to help themselves and one another |
Electroconvulsive therapy | Treatment of last resort for severe depression that involves passing an electrical current through a person's brain in order to induce a seizure |
Psychodynamic therapy | Therapy aimed at uncovering unconscious motives that underlie psychological problems |
Psychoanalytic therapy | Based on Freud's ideas, therapeutic approach oriented towards major personality change with a focus on uncovering unconscious motives, especially through dream interpretation |
Psychotherapy | The use of psychological techniques to modify maladaptive behaviors or thought patterns or both, and to help patients develop insight into their own behavior |
Postconventional level | Stage 3/3 of Kohlberg's theory of moral reasoning in which the person recognizes universal moral rules that trump unjust or immoral local rules |
Preconventional level | Stage 1/3 of Kohlberg's theory of moral reasoning in which a person focuses on avoiding punishment or maximizing reward |
Conventional level | Stage 2/3 of Kohlberg's theory of moral reasoning in which a person values caring, trust, and relationships, as well as the social order and lawfulness |
Parasympathetic nervous system | Part of the autonomic nervous system that relaxes and calms the body |
Egocentrism | Viewing the world from one's own perspective and not being capable of seeing things from another person's perspective |
Conservation | Recognition that when some properties (such as shape) of an object change, other properties (such as volume) remain constant |

Object permanence | The ability to realize that objects still exist when they are not being sensed (4-9 months) |
