Memory
100

This part of the nervous system controls voluntary muscle movements.

Somatic nervous system 

100

This organization creates the ethical guidelines that psychologists in the U.S. are expected to follow.

American Psychological Association (APA)

100

This stage of sleep is when most dreaming occurs and your brain is very active, even though your body doesn’t move.

REM (Rapid Eye Movement)

100

This sense uses mechanoreceptors in the skin to detect pressure, temperature, and pain.

somatosensory system

100

This is the first stage of memory that holds sensory information for a brief moment.

Sensory Memory 

200

This division of the autonomic nervous system is responsible for calming the body down after a stressful event.

Parasympathetic nervous system

200

This term refers to a participant's agreement to take part in a study after being informed of what it will involve.

informed consent

200

These rapid brain waves are present during the awake, alert state and are associated with active thinking.

beta waves

200

This sensory system detects chemicals through taste buds and includes sweet, salty, sour, bitter, and umami.

gustatory system

200

This type of memory refers to facts and general knowledge and is part of explicit memory.

semantic memory

300

These are the basic building blocks of the nervous system that transmit information through electrical and chemical signals.

Nuerons

300

In certain studies, researchers may withhold the full purpose of the study from participants. What is this called?

deception

300

This hormone, released by the pineal gland, helps regulate the sleep-wake cycle.

melatonin

300

This part of the eye adjusts the pupil size and helps regulate the amount of light entering the eye.

iris

300

This phenomenon occurs when earlier learning interferes with the recall of newer information.

proactive interference

400

This brain structure is responsible for coordinating movement and balance and is often called the "little brain."

cerebellum

400

This process must occur after a study, especially if deception was used, to explain the true nature of the research to participants.

debriefing 

400

During this stage of non-REM sleep, delta waves dominate, and it's the hardest stage to wake someone from.

Stage 3

400

Located in the cochlea, these specialized cells convert sound vibrations into neural signals.

hair cells 
400

The hippocampus plays a key role in forming this type of long-term memory.

explicit (or declarative) memory

500

This neurotransmitter is involved in mood regulation and is commonly linked to depression when its levels are low.

serotonin

500

This ethical principle ensures that personal information and results from a psychological study are not shared publicly.

Confidentiality 

500

This 24-hour biological cycle helps regulate when we feel sleepy or awake.

circadian rhythm

500

This sensory system is unique because it sends information directly to the limbic system, bypassing the thalamus.

olfactory system

500

This process involves strengthening of neural connections and is believed to be the biological basis for memory.

long-term potentiation (LTP)
