aims to solve practical problems

Basic Research

pure science that aims to increase the scientific knowledge base

Hypothesis

is a testable prediction, often induced by a theory, to enable us to accept. reject, or revise the theory (educational guess)

IV

a factor, manipulated by the experimenter, and whose effect is studies

DV

a factor that may change in response to the IV

Theory

an explanation using an integrated set of principles that organizes observations and predicts behaviors or events

Operational definition

a clear statement of what one is looking for in an experiment

Validity

the extent to which a test measures or predicts what it is supposed to

Reliability

it is replicable and is consistent

Sampling

process by which participants are selected

Population

the amount of participants that can be selected for the sample

Representative sample

take the results from a smaller group and apply that to a larger group of people

Random Sample

everyone has an equal chance of being selected for the experiment because the participants are chosen at random

Control Group

group that does not take part in the critical part of the experimentation process, used as a comparison group

Experimenter bias

the experimenter, either unconsciously or consciously, affects the outcome of the experiment

Single-blind procedure

the subjects do not know to what group they belong

Double-blind procedure

neither the experimenter nor the subject knows to what group the subjects are in

Hawthorne Effect (Observation Bias)

if you know you're being studied, you will act differently than you normally/typically would

average of the scores, add them up and divide by total number of scores

Median

middle score - when all scores are put numerically in order, the middle score

Mode

he most frequently occurring score in the distribution

Range

Standard Deviation

the average distance of scores around the mean - 68%

Z-score

Myelin Sheath

a fatty covering around the axon of some neurons that speeds neural impulses

Axon

wire-like structure ending in the terminal that extends from the cell body

Neurons

a nerve cell; the basic building block of the nervous system

Sensory Neurons (afferent)

neurons that carry incoming information from the sensory receptors to the brain and spinal cord

Interneuron

Central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs

Motor Neurons

neurons that carry incoming information from the central nervous system to the muscles and glands

Neurotransmitters

chemical contained in terminal buttons that enable neurons to communicate; they fit into the receptor site of neurons like a key fits into a lock

Central Nervous System (CNS)

brain and spinal cord

Peripheral Nervous System (PNS)

the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body.

Somatic Nervous System

the division of the PNS that controls the body's skeletal muscles

autonomic nervous system

The part of the PNS that controls the glands and the muscles of the internal organs.

calms the body

Pituitary gland

connected to the base of the brain stem, controls our blood pressure, heart rate, and breathing
