QUESTIONS AND CORRECT ANSWERS
What is perception? - CORRECT ANSWER Our awareness of our environment and
stimulus. And how we perceive them
What are sensations - CORRECT ANSWER Unconscious experiences generated by
stimulation of a sense eg: camera flash in eye
Other things to know about sensations - CORRECT ANSWER Sensation does not
equal perception!Sensory information is processed by our brains to give us perception. It is
the information sent to our Brain by our senses
What is the order of processing - CORRECT ANSWER Stimuli(vision) -> operation of
senses (recognising light through optic nerve)-> sensory processing -> perception(becoming
aware) -> organisms response
What is the relevance to psychology of perception ? - CORRECT
ANSWER Perception is the foundation for everything else: memory , learning, motor
skills, emotion, motivation, social psychology and pathology
Why do we need perception? - CORRECT ANSWER All living creatures require the
ability to sense various forms of energy in the environment. Without such ability creatures
cannot respond to significant objects and events
What are the types of senses? - CORRECT ANSWER 1. Vision
2. Auditory (hearing)
3. Olfactory ( smell)
4. Tactile (touch)
5. Gustatory (taste)
6. Balance
,Visual memory diagram ? - CORRECT ANSWER Stimuli -> vision -> (passive
attention. Moving eye to ball ) -> sensory memory (1-3 seconds. Having flash in eye and it
staying there) -> working memory (20-30 seconds. Active attention) -> (encoding) -> long-
term memory (1 second- lifetime) -> retrieval
Two different worlds? And an example - CORRECT ANSWER Physical world- all
stimuli exist. Sensory input. Smells, hearing voices ect.
Perceptual world- our brains interpretation of that input
Example- black/blue and gold/white dress meme
What is the classification of senses and the receptors? - CORRECT ANSWER Vision -
Photoreceptors
Hearing - Mechanoreceptors
Touch - Mechanoreceptors + Thermoreceptors
Taste/Smell - Chemoreceptors
Balance - Mechanoreceptors + vestibular organs
What are photoreceptors - CORRECT ANSWER A specialised nerve cell that produced
electrical signal when struck by light
Where is our primary visual cortex ? - CORRECT ANSWER In our occipital lobe.
Bottom
Marr's Model of vision - CORRECT ANSWER Marr's ideas were the beginning of
computational neuroscience
Stages that visual processing passes through stages:
- Primal sketch
- 2.5D (2D with illusion of depth) sketch
, - 3D sketch
Classification of hearing - CORRECT ANSWER Hearing -> air pressure waves ->
mechanoreceptors -> ears -> auditory cortex
What are mechanoreceptors? - CORRECT ANSWER A specialised nerve cell that
produced electrical signal when subjected to mechanical deformation.
- Perceived through skin, muscle and vestibular organs stimulated through tissues, distortion,
gravity and acceleration
What is touch blindness? - CORRECT ANSWER - Inability to feel touch, can
sometimes inhibit pain feeling
- Touch and pain receptors reduce in accuracy as we age
Where is our auditory cortex? - CORRECT ANSWER Temporal lobe. Middle bottom
Classification of touch - CORRECT ANSWER Touch -> tissue distortion ->
mechanoreceptors themoreceotors -> skin muscles -> somatosensory cortex
Where is our somotosensory cortex ? - CORRECT ANSWER Small part in the middle
Classification of taste/ smell - CORRECT ANSWER Taste/ smell -> chemical ->
chemoreceptors-> nose/ mouth -> taste and olfactory cortex
Where is our taste and olfactory cortex I'm the brain? - CORRECT ANSWER All over.
Gustatory (taste) cortex, cerebral cortex, olfactory cortex
Classification of balance - CORRECT ANSWER Balance -> . -> mechanoreceptors ->
vestibular organs -> temporal cortex
