Sensory snd Perception (3a)

Question 1

Grapheme-color synesthia

Answer 1

Seeing a specific colour in relation to a latter or number

Question 2

Other forms of synthesia

Answer 2

• Smelling a particular odour when responding to touch
• hearing noises in response to smell
• feeling tactile stimulus in response to sight
• Experiencing unpleasant motions elicited by specific sounds

Question 3

Sensation

Answer 3

Is the act of using our sus theory system to detect environmental stimuli

Question 4

Perception

Answer 4

The conscious recognition and identification of a sensory stimulus

Question 5

Sensory transduction

Answer 5

Converts environmental stimuli into neural activity

Question 6

Sensory receptors cells

Answer 6

Specialized cells that convert a specific form of environmental stimuli into neural impulses

Question 7

Sensory transduction

Answer 7

The process of converting a specific form of environmental stimuli into a neuronal impulse that our brain can read

Question 8

Absolute threshold

Answer 8

The smallest amount of stimulus that one can detect

Question 9

Difference threshold

Answer 9

The minimal difference needed to notice a difference between two stimuli

Question 10

Signal detection theory

Answer 10

The response to a signal in every situation depends on an individuals ability to differentiate between the signal and noise and on their response criteria

Question 11

Sensory adaptation

Answer 11

Reseated stimulation of a sensory cell that leads to reduced response

• the tag on your shirt that bothered you this morning,but nor you don’t even notice it

Question 12

Bottom up processing

Answer 12

Perception that proceed by transduction enviormental stimuli into neural impluses that more successively into more compelct Brian regions.
- starts from the most basic form from environmental stimuli and builds to more complex components

Question 13

Top down processing

Answer 13

Perception processes led by cognitive precise such as memory or expectation

• starts from complex components and works down to more simple

Question 14

Perceptual set

Answer 14

Is the readiness to interpret a certain stimulus in a certain way

Question 15

Odourants

Answer 15

Airborne chemicals that are detected as odours

Question 16

Olfactory reception neurons

Answer 16

Sensory receptor cells that convert chemical signals from odourants into neural impulses that travel to the brain

Question 17

Papillae

Answer 17

Umps on the tongue that contain clumps of taste buds

Question 18

Taste buds

Answer 18

Clusters of sensory receptors cells that convert chemcial signals from food into neural impulses that travel to the brain

Question 19

Five taste receptors on your tongue

Answer 19

Sweet
Sour
Bitter
Salt
Umami

Question 20

eating, taste, smell

Answer 20

Overall sensations from eating are based on more that smell and sates consistency of food id related to the brain by inputs from touch receptors located on the tongue

Question 21

Development of smell and taste

Answer 21

Smell is realativly well developed at brith, newborns can show a preference for the odour of their mothers mil. They also show a preference for sweet and an aversion to bitter

Question 22

Individual differences in taste and smell

Answer 22

Females are generally more sensitive to odours than males
Taste is variable in individuals; some are more sensitive to bitter substances than others

Question 23

Ageusia

Answer 23

Inability o taste, a rare disorder
