Term
Afferent nerves
Definition
Sensory nerves- carry information about the external environment to
the brain and spine using sensory receptors.
Term
Efferent nerves
Definition
Motor nerves- carry information from the brain and spine to other parts of the body.
Term
Neural Networks
Definition
Interconnected groups of nerve cells that integrate sensory input and motor output
Term
Central nervous system
Definition
Brain and spinal cord
Term
Peripheral nervous system
Definition
The network of nerves that connects the brain and spinal cord to the other parts of the body. Somatic & autonomic connect
Term
Somatic nervous system
Definition
Sensory nerves whose function is to convey information from the skin and muscles to the CNS [ pain, temp ]
Term
Autonomic nervous system
Definition
Takes messages to and from the body’s internal organs monitoring such process as breathing heart rate and digestion.
Term
Sympathetic nervous system
Definition
Arouses the body to mobilize it for ation and thus is involved in the experience of stress
Term
Parasympathetic nervous system
Definition
Calms the body
Term
Stress
Definition
The body’s response to stressors
Term
Neurons
Definition
Nerve cells that handle the information-processing function.
Term
Glial cells
Definition
Provide support nutritional benefits and other functions in the nervous system.
Term
Cell body
Definition
Contain the nucleus, which directs the manufacturer of substances that the neuron needs for growth and maintenance.  
Term
Dendrites
Definition
Treelike fibers projecting from a neuron, receive information and orient it towards the neuron's cell body
Term
Axon
Definition
Part of the neurons that carries information away from the cell body towards other cells.  
Term
Myelin sheath
Definition
Consisting of a layer containing fat, encases and insulates most axons
Term
Resting potential
Definition

 

The stable, negative charge of an inactive neuron

Term
Action potential
Definition
Describes the brief wave of positive electrical charge that sweeps down the axon
Term
All or nothing principle
Definition
When electrical impulse reaches a certain level of intensity, called its threshold, it fires and moves all the way down the axon without losing any of its intensity  
Term
Synapses
Definition
Tiny spaces between neurons
Term
Neurotransmitters
Definition
Chemical stores in very tiny synaptic vacs
Term
Agonist
Definition
A drug that mimics or increases a neurotransmitter’s effects
Term
Antagonist
Definition
A drug that blocks a neurotransmitter’s effects
Term
Cerebral cortex
Definition
Part the forebrain and is the most recently developed part of the brain in the evolutionary scheme
Term
Neocortex
Definition
Is the outermost part the cerebral cortex
Term
Occipital lobes
Definition
Located at back of the head respond the visual stimuli
Term
Parietal lobes
Definition
Located at the top and towards the rear of the head, are involved in registering spatial location, attention and motor control
Term
Temporal lobes
Definition
The part of the cerebral cortex just above the earsm involved in hearing language processing and memory
Term
Frontal lobes
Definition

 

The portion of the cerebral cortex behind the forehead are involved in personality, intelligence, and the control of voluntary muscles

Term
Psychology
Definition
Scientific study of all the behaviors (beh) and mental process.
Science→ Using systematic methods to observe human behavior and draw conclusions.
Term
Behavior
Definition
Everything we do that can be directly observed.
Term
Mental Processes
Definition
Thoughts, feelings, and motives that each of us experience privately but that cannot be observed directly.
Term
Critical thinking
Definition
The process of thinking deeply and actively, asking questions and evaluating the evidence.
Term
Empirical method
Definition
Involves gaining knowledge by observing events, collecting data and reasoning logically.
Term
Structuralism
Definition
Focus on identifying the element parts of structures of the human mind
Term
Biological approach
Definition
Focus on the body, especially the brain and the nervous system
Neuroscience
Term
Behavioral approach
Definition
Study of observable behavioral responses and their environmental determinants. [ Visible Beh ]
Term
Psychodynamic approach
Definition
Unconscious thought, the conflict between biological drives [ Sex ] and society’s demands, & early childhood family experiences.
Term
Humanistic
Definition
Person’s positive qualities, the capacity for positive growth, and the freedom to choose one’s destiny.
Term
Cognitive approach
Definition
The mental process involved in knowing how we direct our attention , perceive, remember, think and solve problems.
Term
Evolutionary approach
Definition
Uses evolutionary ideas such as adaptation, reproduction and natural selection the basis for explaining specific human behaviors
Term
Sociocultural approach
Definition
Examines the influences of social and cultural environments on behavior.
Term
Variable
Definition
Anything that can change
Term
Theory
Definition
Broad idea or set of closely related ideas that attempts to explain observations
Term
Hypothesis
Definition
Testable prediction that derives logically from a theory
Term
Observational Method
Definition
An objective description of how variables is going to measured and observed in a particular study.
Term
Case Study or Case History
Definition
Relationships between variables, and its purpose to examine whether one of the variables increases, what happens to the other?
Term
Longitudinal design
Definition
Observing and measuring the same variables periodically over time.
Term
Experiment
Definition
A carefully regulated procedure in which the research manipulate one or more variables that are believed to influence some other variable.
Term
Random assignment
Definition
Researchers assign participants to groups by chance.
Term
Independent variable
Definition
Manipulated experiment factor.
Term
Confederate
Definition
Person who is given a role to play in a study so the social context can be manipulated.
Term
Dependent variable
Definition
The outcome- the factor that changes in an experiment.
Term

Term
Control group
