Sleep/Consciousness
the biological clock that helps regulate sleep and wake cycles
Circadian rhythm
The sleep disorder that involves a person waking up in the middle of the night because they stop breathing
Sleep Apnea
Diminished sensitivity as a consequence of constant stimulation
Sensory adaption
What part of the eye allows a person to see colors
Cones
Which research method involves random assignment and manipulation of variables?
Experiment
The stage of sleep where dreaming occurs
REM sleep
Sleep disorder where the person randomly falls asleep triggered by a strong emotion
Narcolepsy
Conversion of one form of energy into another
Transduction
the process by which the eye’s lens changes shape to focus near or far objects on the retina
Accomodation
variable that changes as a result of the independent variable
Dependent variable
Large, slow brain waves associated with deep sleep
Delta waves
Sleep disorder where a person kicks and punches in their sleep when muscle movement should not be possible
REM sleep behavior disorder
The minimum stimulus energy needed to detect a particular stimulus 50% of the time
Absolute threshold
The point at which the optic nerve leaves the eye
Blind spot
the group exposed to the treatment
Experimental group
What scans help track sleep waves?
EEG
Dream theory that suggests sleeping allows for the brain to remember information better
Information processing/ consolidation
Guided by higher-level mental processes; constructing perceptions on our experience and expectations
Top down processing
The spinal cord contains a neurological “gate” that blocks pain signals or allows them to pass on to the brain
Gate-control theory
a carefully worded statement of the exact procedures used in a research study
Operational definition
the principle that information is often simultaneously processed on separate conscious and unconscious tracks
Dual processing
Dream theory where the brain is trying to make sense of information gained throughout the day
Activation synthesis
the principle that two stimuli must differ by a constant minimum percentage to be perceived differently
Weber's Law
Links the pitch we hear with the place where the cochlea’s membrane is stimulated
Place theory
The four ethical guidlines for an experiment
1. Informed consent 2. No greater than usual harm 3. Keep information confidential 4. Debrief participants
