Contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.

Term
Experimental group
Definition
In an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable.
Term
Random assignment and random sample
Definition

Random assignment - Assigning participants to experimental and control groups by chance, thus minimizing preexisting difference between those assigned to the different groups (pg. 31)

 

Random sample - A sample that fairly represents a population because each member has an equal chance of inclusion (pg. 24)

Term
Double-blind procedure
Definition

An experimental procedure in which both the research participants and the research staff are ignorant (blind) about whether the reseach participants have received the treatment or a placebo.

 

Commonly used for drug studies

Term
Operational definition
Definition

A statement of the procedures (operations) used to define research variables. 

 

Example: human intelligence may be operationally defined as what an intelligence test measures

Term
Independent and dependent variables
Definition

Independent variable - variable that is manipulated

Term
Experiment
Definition

A research method in which an investigator manipulates one or more factors (indepedent variables) to observe the effect on some behavior or mental process (the dependent variable). 

 

By random assignment of participants, the experimenter aims to control other relevant factors.

Term
Correlation
Definition

A measure of the extent to which two factors vary together and thus of how well either factor predicts the other (pg. 25)

 

Correlation does not mean causation!

You draw samples from a population.

Term
Biological Psychology
Definition

A branch of psychology concerned with the links between biology and behavior (pg. 48)

 

Everything psychological is also biological.

Term

Definition

Dendrite - the bushy, branching extentions of a neuron that receive messages and conduct impulses toward the cell body (pg. 49)

 

Receive messages

 

 

Term
Axons
Definition
Axon - The extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands
Term
Synapse
Definition

The junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron (pg. 51)

 

Important in pain medications because they fill receptors in the synapse preventing the sensation of pain

Term
Action Potential
Definition

A neural impulse.

 

A brief electrical charge that travels down an axon.

 

The cell body uses to decide whether to fire.

Term
Threshold
Definition

The level of stimulation required to trigger a neural impulse (pg. 50)

 

Minimum level of intensity of action potential.

Term
Reuptake
Definition
A neurotransmitter's reabsorption by the sending neuron (pg. 51)
Term
Sympathetic Nervous System
Definition

Sympathetic Nervous System - The division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations (pg. 55)

 

Arousing part of autonomic nervous system

 

Fight or flight

Term
Parasympathetic Nervous System
Definition

The division of the autonomic nervous system that calms the body, conserving its energy

 

Calming

 

Rest and digest

Term
Central Nervous System
Definition
The brain and the spinal cord
Term
Cerebellum
Definition

The "little brain" at the reat of the brainstem

 

Functions include processing sensory input and coordinating movement output and balance (pg.64)

 

Coordinates voluntary movements and balance

Term
Corpus Callosum
Definition
The large band of neural fibers connecting the two brain hemispheres and carrying messages between them (pg. 75)
Term
"Split Brain" Patients
Definition

Split brain - A condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them (pg. 75)

Brain reteaches other parts of the brain to do what damaged part did

Term
Left brain vs. right brain
Definition

Left brain: writing and speaking

Right brain: artisitic and creative

Term
Consciousness
Definition
Our awareness of ourselves and our environment (pg. 86)
Term
Dreaming: Latent and manifest content
Definition

Dream - a sequence of images, emotions, and thoughts passing through a sleeping person's mind. Dreams are notable for their hallucinatory imagery, discontinuities, and incongruities, and for the dreamer's delusional acceptance of the content and later difficulties remembering it.
