Social Psychology
the study of how the presence of other people influences the ways we think, feel, and behave
Self-identity
the way we understand ourselves in relation to others
Attribution
quick cognitive processes that happen outside of our conscious awareness to give a reason that people do things
Internal Attribution
inference that it’s internal issues

Cognitive Psychology
approach emphasizes the mental processes involved in perception, decision-making, problem solving, and the ways we construct meaning; suggests that distorted patterns of understanding and interpreting experiences and relationships are responsible for abnormal thoughts and behaviors
Biological Psychology
approach emphasizes biological structures and electro-chemical processes; explains motivation in terms of instincts, drives, and needs; explains mental illnesses as diseases of the mind that, like ordinary physical diseases have discrete physical causes
Behavioral Psychology
approach emphasizes the relationship between environmental influences and behavior, along with what has been reinforced; explains motivation in terms of external forces, rewards, and consequences; suggests that abnormal thoughts and behaviors are learned by association, punishment, and reinforcement
Humanistic Psychology
approach emphasizes thoughts, feelings, and innate human goodness and potential; explains motivation in terms of an intrinsic human need to grow and achieve; explains mental illnesses in terms of circumstances blocking one's progress toward self-actualization
Psychoanalytic Psychology
emphasizes unconscious processes; explains mental illnesses in terms of unconscious psychic conflicts

focused on discovering survival and reproductive advantages that behaviors and mental functions provided
Wilhelm Wundt
credited as the founder of scientific psychology, established a psychology laboratory at the University of Leipzig in 1879
Williams James
father of American psychology, theorized that consciousness and emotions evolved as a complex mix of physical processes that equipped our ancestors for the challenges of survival
Reductive
mental structures and behaviors consist of even simpler component structures and behaviors
Moral Relativism
worldview in which standards of behavior are based on an individual's temporal framework of values and beliefs and not on any absolutes
The Study of the Brain and Nervous System
neuro-psychology, neuro-anatomy, neuro-biology
Dendrites and Axons
specialized extensions that neurons use to communicate with each other
Motor Neurons
carry signals from the brain and spinal cord to the muscles and glands
Sensory Neurons
carry signals from the sense receptors in the body to the brain
Interneurons
exist exclusively in the brain and spinal cord and make up about 90% of all human neurons
Excitatory Neurotransmitters
the chemical signal increases the likelihood that neighboring neurons will fire
Inhibitory Neurotransmitters
the signal lowers the likelihood that other neurons will fire
Peripheral Nervous System
consists of all the neurons running throughout the body outside of the brain and spinal cord; divided into somatic and autonomic
Autonomic Nervous System
controls involuntary body functions like circulation, respiration, perspiration, and digestion; divided into the sympathetic and parasympathetic nervous systems
Phineas Gage
metal rod driven through his head, accident demonstrated that there is a connection between the brain and personality
Glial Cells
support neural functioning by digesting dead neurons, producing myelin sheathing, and providing nutrition to neurons
Psychotropic Medications
affect the supply of neurotransmitters or the way in which they are absorbed
Central Nervous System
consists of the brain and spinal cord
Neuron
most basic building block of the nervous system
Somatic Nervous System
controls voluntary muscle movement and makes connections between the motor cortex of the brain and the muscles used in movement
Electroencephalograph (EEG)
records electrical voltage produced when neurons fire, shows brain activity
Computer Axial Tomography (CT scan)
involves rotating an x-ray machine around the brain to produce a series of images, shows brain structure
Positron Emission Tomography (PET scan)
produces real-time three-dimensional images of the brain at work, shows both brain structure and activity
Magnetic Resonance Imaging (MRI)
uses magnetic fields and radio waves to create detailed images of the brain, shows both brain structure and activity
Sympathetic System
creates an excited state and mobilizes the body for action by accelerating some functions and decelerating others
Parasympathetic System
restores the body to a state of rest and relaxation
Forebrain
largest part of the brain making up about two-thirds of the brain's size; includes the cerebral cortex, thalamus, hypothalamus, amygdala, and hippocampus
Corpus Callosum
nerve fibers connecting the left and right hemispheres
Amygdala
almond shaped structure located deep in the temporal lobe and plays a role in fear and other emotions, learning, memory, attention, and perception
Cerebellum
second largest structure in the brain and is associated with movement, coordination, balance, and motor-related memory
Psyche
means mind/soul
ABC's of Psychology
affect (emotions), behavior, cognition
Nervous System
most complex system in the known universe; made up of the Central and Peripheral
Naturalism
worldview that believes all mental activity must ultimately be nothing more than biochemical processes and can be applied to all psychological approaches
Lobotomy
developed by Egas Moniz, psycho-surgery involving removal or alteration of part of the brain
Neuro-transmission
process of converting physical stimuli into neural energy
Absolute Threshold
refers to the minimum intensity of a stimulus that will stimulate an organ to operate. The lowest intensity of something we can sense

Vestibular System
provides the sense of balance and the information about body position that allows rapid compensatory movements in response to both self-induced and externally generated forces.
Motivation
inner state and process that arouses, directs, maintains, and terminates behavior; intrinsic- coming from within; extrinsic- coming from an outside force
Reflexes
automatic, involuntary, and unlearned patterns of behavior that are triggered by particular stimuli
Drive Reduction Theory
biological needs (drives) are the primary motivator of human behavior
Drives
unpleasant internal states of tension which arouse us to take action to meet the need, restore homeostasis, and reduce internal tension
Abraham Maslow
father or humanistic psychology; believed people are born with a motivation to grow toward self-actualization; made the hierarchy of needs
Arousal Theory
we are motivated to achieve our individually optimal state of arousal

Sensory Memory
like a temporary buffer of memory where information is held very briefly and evaluated for further processing
Latent Learning
a form of learning that is not immediately demonstrated or needed and occurs without direct reinforcement
Social Learning
theory proposes that we learn from one another through observation, imitation, and modeling
