This part of the nervous system controls voluntary muscle movements.
Somatic nervous system
This organization creates the ethical guidelines that psychologists in the U.S. are expected to follow.
American Psychological Association (APA)
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)
This sense uses mechanoreceptors in the skin to detect pressure, temperature, and pain.
somatosensory system
This is the first stage of memory that holds sensory information for a brief moment.
Sensory Memory
This division of the autonomic nervous system is responsible for calming the body down after a stressful event.
Parasympathetic nervous system
This term refers to a participant's agreement to take part in a study after being informed of what it will involve.
informed consent
These rapid brain waves are present during the awake, alert state and are associated with active thinking.
beta waves
This sensory system detects chemicals through taste buds and includes sweet, salty, sour, bitter, and umami.
gustatory system
This type of memory refers to facts and general knowledge and is part of explicit memory.
semantic memory
These are the basic building blocks of the nervous system that transmit information through electrical and chemical signals.
Nuerons
In certain studies, researchers may withhold the full purpose of the study from participants. What is this called?
deception
This hormone, released by the pineal gland, helps regulate the sleep-wake cycle.
melatonin
This part of the eye adjusts the pupil size and helps regulate the amount of light entering the eye.
iris
This phenomenon occurs when earlier learning interferes with the recall of newer information.
proactive interference
This brain structure is responsible for coordinating movement and balance and is often called the "little brain."
cerebellum
This process must occur after a study, especially if deception was used, to explain the true nature of the research to participants.
debriefing
During this stage of non-REM sleep, delta waves dominate, and it's the hardest stage to wake someone from.
Stage 3
Located in the cochlea, these specialized cells convert sound vibrations into neural signals.
The hippocampus plays a key role in forming this type of long-term memory.
explicit (or declarative) memory
This neurotransmitter is involved in mood regulation and is commonly linked to depression when its levels are low.
serotonin
This ethical principle ensures that personal information and results from a psychological study are not shared publicly.
Confidentiality
This 24-hour biological cycle helps regulate when we feel sleepy or awake.
circadian rhythm
This sensory system is unique because it sends information directly to the limbic system, bypassing the thalamus.
olfactory system
This process involves strengthening of neural connections and is believed to be the biological basis for memory.
long-term potentiation (LTP)
