Exam Review Flashcards
operational definition
a carefully worded statement of the exact procedures used in a research study.
a measure of the extent of how much one variable changes the other
Correlation
Correlation Coefficient
statistical index of the relationship between two variables
Experiment
a research method in which the experimenter manipulates one or more factors to observe the effect on some behavior or mental process
Validity
how correct the experiment is
Neuron
a nerve cell. (basic building block of nerve cell)
Axon
the neuron extension that passes messages through its branches to other neurons or to muscles and glands
Action Potential
electrical charge that travels down an axon
Central vs. Peripheral Nervous System
Central: The brain and spinal cord
Peripheral: gathering information and transmitting CNS decisions to other body parts
Thalamus
the brains sensory control center
hypothalamus
directs eating, drinking, and body temperature. Linked to reward and emotion
Cerebral Cortex
ultimate control and information processing center (higher processing)
Temporal Lobe
Hearing
Occipital Lobe
includes areas that receive information from visual views (Sight seeing)
Parietal Lobe
lies at the top of the head and receives information for sensory input for touch and body position
Frontal Lobe
involves speaking, muscle movement and making plans and judgments
Corpus Collosum
connects hemispheres
Left Brain
language and math
Right Brain
Artistic and music
Broca’s Area
language expression
Wernicke’s Area
language reception
Transduction
transforming signals into neural impulses
Sensory Adaptation
not hearing the clock tick because you are so focused on Mr. jennerjohn talking
Signal Detection Theory
theory predicting how and when we detect the presence of a faint stimulus. (Someone expecting an important text so they are more likely to feel a soft buzz)
Weber’s Law
Theory that say JND is based on %
Sensation
window to outside world (physical aspect)
Perception
Interpreting what comes in the window
Rods
More of them. on outsides of eye. low color. low detail. High sensitivity in dim light
Cones
Less of them. right in the middle. high detail. high color. low sensitivity in dim light
Trichoromatic Theory
three types of cones: Red, Blue, Green
Opponent process Theory
Sensory receptors come in pairs: red/green blue/yellow black/white
