Term
Psychology.
Definition
Discipline concerned with behavior and mental processes and how they are affected by an organism’s physical state, mental state, and environment.
Term

 

Biological Perspective.

Definition

 

 

Emphasizes changes in behavior due to bodily events that are associated with actions, feelings, and thoughts.
Term

 

Learning Perspective

Definition

 

 

Emphasizes changes in an organism’s actions due to the environment and experience.
Term

 

 Cognitive Perspective.

Definition

 

Emphasizes that changes in behavior are due to mental processes like memory, language, and problem solving.

Definition

 

 

Early Psychological approach that emphasized the function or purpose of behavior or consciousness.
Term

 

Critical Thinking.

Definition

 

Ability and willingness to assess claims and make objective judgments’ on the basis of well supported reasons and evidence, rather than emotions or anecdotes.

Cross sectional study

Definition

 

Study where subjects of a different age are compared at any given time.

Term

 

Placebo

Definition

 

Inactive Substance or fake treatment used as a control in a experiment or given to a patient by a medical practitioner.

Term

 

 

double blind

Definition

 

experiment where neither the subjects or individuals running the study know which group of subjects is the control and which is the experiment until after the results are in.

Term

 

 

Glial Cells

Calls that aid nuerons by giving them nutrients, insulation, and removing their debris once they die.

Term
Occipital Lobe
Definition
Back of the brain that contains the visual cortex

Term
Dendrites
Definition
Branches of a neuron that recieve info from other neurons + transmits them to cell body
Term
Cell Body
Definition
Part of the neuron that keeps the cell alive and determines whether it will survive or not.
Term
Axon
Definition
Extending fiber in which conducts impulses away from the cell body and transmits them to other neurons/muscles/glail cells
Term
myaxon terminals
Definition
divided axon branches
Term
synapse
Definition
site where nerve impulse is transmitted from one nerve cell to another
Term
They don't travel to the brain.
