Sensation And Perception Flashcards
What senses do we have?
Gestation (taste)
Olfaction (smell)
Vision
Touch
Audition (hearing)
Proprioception (body awareness)
Vestibular (sense of balance and allows us to move smoothly)
Pain
Temperature
__________enables a person to close their eyes and touch their nose with their index finger.
Proprioception
What is the connection between the physical world and the psychological world?
The physical world converts one form of energy to the psychological world. Such as light is transformed into brightness and sound is transformed into volume.
Define transduction
Converting one form of energy to another
What does transduction focus on?
Translating our sense biologically
Smelling a drop of perfume in a three bedroom apartment is also known as
Sensory threshold
A candle flame 30 miles on a dark, clear night is an example of
Sensory threshold
A drop of perfume from three rooms away is an example of
Sensory threshold
Define sensory threshold
Minimum stimulation necessary to detect light, sound, pressure, taste, and odor 50% of the time
Define subliminal threshold
A message passed through a human mind without being consciously aware (less than 50% of the time)
Define Weber’s law
The perception of change in any given stimulus is always dependent on what the stimulus is
If you have a cup of coffee that has only 1 tsp of sugar, adding another tsp of sugar will make a big difference in taste is an example of
Weber’s law
Sensory adaption is the reduce in sensitivity to a stimulus after constant exposure. True or false.
True
Once I walk into my moms car, I noticed an odor that bothered me. After 5 minutes, I can’t smell the odor in her car. This is an example of
Sensory adaptation
What is the term that uses both eyes to focus on the same object?
Convergence
Where does transduction occur?
Transduction occur in rods located in the retina
What happens when light enter the pupil and cornea?
Light hit the transparent disc (lens) then focus the light rays into specific images into the retina
What chemical change does rods and cones trigger?
Neural signals which then activates the bipolar cells that turn on the ganglion cells
Which part of our brains detect faces?
Temporal lobe
Which part of our brain detect houses?
Parietal lobe
Which part of our brain detect chairs
Inferotemporal cortex
Define parallel processing and give an example
Processing many information at the same time such as color, motion, shape. For example, when you see a bus coming towards you, you detect the shape, the speed, and the color of the bus
We all see electromagnetic spectrum. T or F.
False. We only see a small portion of this spectrum.
