Research Methods
Group of participants who are not treated in the particular way that the experimental group is treated in an experiment
Control group
Only study in which cause and effect can be determined.
What is experiment
Gap between axon and receiving dendrite across which neurotransmitters pass.
synapse
Includes the primary visual cortex, where visual information is received
Occipital Lobe
When people fail to detect changes to the visual details
Change Blindness
Purposely manipulated factor thought to produce change in an experiment.
What is independent variable
Tendency to have consistently similar measurements over multiple trials.
Reliability
Acts as a bridge so that information can be shared across both hemispheres of the brain
Corpus Callosum
Part of the autonomic nervous system that prepares the body to react to threatening situations
What is sympathetic nervous system?
One doesn’t notice some significant object or event that is in clear field of vision.
What is Inattentional blindness:
A research strategy that allows the precise calculation of how strongly related two factors are to each other
What is correlation
Process in which subjects are selected randomly from a larger group such that every group member has an equal chance of being included in the study
What is random selection
Multiple short fibers that extend from the neuron’s cell body and receive information from other neurons or from sensory receptor cells.
Dendrite
An "all-or-nothing" process in which an electrical signal is conducted along the neuron's axon to the synapse.
What is an action potential?
Smallest strength of a stimulus that can be detected by the senses
What is Absolute threshold
Highly detailed description of a single individual Generally used to investigate rare, unusual, or extreme conditions
What is case study
A fake substance, treatment, or procedure that has no known direct effects
What is Placebo
Outer layer of the brain containing high concentration of neurons.
Cerebral Cortex
Gland in the brain required to form new memories
Hippocampus
Photoreceptors responsible for best acuity and for color vision
What is cones
A selected segment that very closely parallels the larger population being studied on relevant characteristics.
What is representative sample
Both the participants and the researchers interacting with them are blinded, or unaware of the treatment or condition to which the participants have been assigned
What is Double-blind technique
Involved in emotional response patterns Learning and memory formation, especially emotional memories. Identifies emotion from facial expressions
What is amygdala?
Receives information from touch receptors in different parts of the body
Parietal Lobe
When sensors in the body convert physical signals from the environment into neural signals sent to the CNS
What is Transduction
