Midterms Flashcards
A direct and specific experience that arises from the stimulation of a sense organ
Sensation
Systems that are widespread throughout the body that detect the world
Receptors
External receptors
Exteroceptors
Internal receptors, detects what’s inside the body. Also our body’s ability to sense movement, action, and location.
Interoceptors and Proprioception
A detectable input from the environment that aids us in obtaining information, resulting in a functional activity.
Stimulus
What are the 2 types of stimulus
Internal and External
The process by which our sensitivity
diminishes when an object constantly
stimulate our senses.
Sensory Adaptation
The conversion of physical into
neural information
Transduction
A type of sensation with the senses of touch and hearing on this for external stimuli.
Mechanoreception
A type of sensation with chemical senses of taste and smell.
Chemoreception
A type of sensation with the process which the visual system transfer light energy that occur naturally in the form of wavelengths into neural messages via the eyes.
Visuoperceptal
The lowest intensity level of a stimulus a
person can detect half of the time
Absolute Threshold
Minimum difference that a
person can detect between
two stimuli 50% at a time
Difference Threshold
A model for predicting how
and when a person will detect
weak stimuli, partly based on context
Signal Detection Theory
This is the process that makes sense of the sensory information that we receive from our surroundings.
Perception
Our perceptions are constructed from
sensory input.
Bottom-up processing
Basing our interpretation on
our understanding of the world, past
experiences and beliefs that shapes
how we interpret those feelings
Top-down processing
List 3 of the identified human senses relating to sight, sound, and taste.
Visual, Auditory, and Gustatory Perception
List 3 of the identified human senses relating to smell, touch, and balance.
Olfactory, Tactile Perception, and Vestibular Sense
Also known as kinesthesia, our sense of self-movement
Proprioception
A gestalt principle stating that perceiving complex visual information as groups of like things. If objects are similar in size, shape, color, brightness, or other shared attributes, humans perceive them as groups and not randomly separate objects.
Similarity
Things that are close together appear to be more related than things that are spaced farther apart
Proximity
when visual elements are aligned with each other, our visual perception is biased to perceive them as continuous forms rather than disconnected segments.
Continuity
Elements enclosed by a common boundary are perceived as a single entity.
Inclusiveness
