Front (Question)

what is sensation?

Back (Answer)

the act of using using our sensory systems to detect environmental stimuli

Front (Question)

what is perception?

Back (Answer)

recognizing and identifying sensory stimulus

Front (Question)

Vision raw sensory data is in the form of…

Back (Answer)

light waves

Front (Question)

hearing raw sensory data is in the form of…

Back (Answer)

sound waves

Front (Question)

smell raw sensory data is in the form of…

Back (Answer)

airborne chemicals

Front (Question)

taste raw sensory data is in the form of…

Back (Answer)

food chemicals

Front (Question)

touch raw sensory data is in the form of…

Back (Answer)

pressure

Front (Question)

What two factors help the transformation of physical stimuli into perception?

Back (Answer)

sensory receptor cells and sensory transduction

Front (Question)

What is the specialized cell that converts a specific form of environmental stimuli into neural impulses?

Back (Answer)

sensory receptor cell

#10

Front (Question)

explain sensory transduction

Back (Answer)

the process of converting a specific form of sensory data into a neural implies that our brain can read

#11

Front (Question)

Different sense have different…

Back (Answer)

receptor cells

#12

Front (Question)

Absolute threshold is the …. amount of a stimulus that one can detect

Back (Answer)

smallest

#13

Front (Question)

Difference in threshold is measured by

Back (Answer)

JND

#14

Front (Question)

What is JND

Back (Answer)

the minimal difference needed to notice a difference between two stimuli

#15

Front (Question)

Different JND depends on the…

Back (Answer)

strength of the original stimulus

#16

Front (Question)

What is sensory adaptation?

Back (Answer)

contant stimulation decreases the number of sensory messages sent to the brain, which causes decreased sensation

#17

Front (Question)

what does sensory adaptation allow?

Back (Answer)

allows us to focus on important stimuli in our environment

#18

Front (Question)

sensation and perception occur together but through different…

Back (Answer)

processes

#19

Front (Question)

What are the two different processes of sensation and perception?

Back (Answer)

bottom top processing and top down processing

#20

Front (Question)

When raw sensory data is transduced, sent to the brain and your brain uses all of the data to build a perception and the neural signals move up to more complex brain regions to start putting together the perception is…..

Back (Answer)

bottom-up processing

#21

Front (Question)

what is top-down processing

Back (Answer)

it is led by cognitive processes where you use previously learned information to help recognize and interpret the data coming into your brain

#22

Front (Question)

What is perceptual set?

Back (Answer)

the readiness to interpret a certain stimulus in a certain way, expecting to see a specific object, you are more likely to interpret it in that way

#23

Front (Question)

perceptual set can affect…

Back (Answer)

all senses

#24

Front (Question)

perception involves both bottom-up process (……) and top-down processes (………)

Back (Answer)

Neural signals to perception, interpretation based on cognitive processes
