Chapter 1, Exam #1 Flashcards
Sensitization
the increase in intensity of a reflex response due to frequent exposure (becoming more sensitive to gunfire in a high crime area)
Reflex
simple involuntary response produced by a specific stimuli (puff of air in eye makes you blink
voluntary response
responses that are primarily controlled by the organism instead of by an unconditioned stimulus and mediated by the somatic nervous system
sensory receptors
proximal stimulus (touch pain vision)
selective attention
we see what captures our attention, interests us, or what we cannot avoid
Central nervous system
includes the brain and spinal cord, stores and processes info that it receives from the environment and other parts of the body then sends messages to other parts of the body
Somatic nervous system
type of peripheral nervous system. controls voluntary responses (muscles tendons ligaments)
parasympathetic nervous system
component of the autonomic nervous system that controls the body when the organism is in a quiet, restful state (peace)
habituation
the lowering of the intensity of a reflex response due to repeated stimulation (not acting as strongly to needles if diabetic)
modal action (fixed action) pattern
one of several types of involuntary responses that is characterized by being an interrelated set of actions involving the whole animal (not just the reaction of part of the animal) specific to a given species, fixed and inflexible, and produced by a single (releasing) stimulus (spider spinning a web)
involuntary respons
a variety of responses types that are usually produced by a limited set of stimuli and primarily mediated by the autonomic nervous system (reflex, instinct)
visual adaption
the process by which the visual system alters its operating properties in response to changes in the environment
perceptual set
auditory, haptic, orientation, savory, and visual
peripheral nervous system
the part of the nervous system that extends out into the peripheral parts of the body
autonomic nervous system
type of peripheral nervous system that controls involuntary responses (breathing, heart rate, sweating)
