Expert Solution

Take a example of hearing .

Suppose you hear maw....maw .....(cat sound)

1)Through Ear you hear ... That maw....maw.... Is *stimulus* for you because it evoke you to respond ....

Eg. Hand in fire .... Fire is stimulus ...

2) sensation :- when you r in kitchen and someone cooking ..

You smells ... And try to recollect thing .. that something is going on in kitchen ... It may be cooking or it may be dead rat smell or rotten egg ...

Similarly . When bike rider going fast next to you without awareness of you ...

You think something was gone from this way ...it may be bike or may be car ...

That your ability to feel what happen around you is* sensation*

3) transduction ..:- it is converting on type of energy to other ..

You hear maw..maw..

Wavefront forms travels from cat to your ear ...in sound form ...

When it strikes to tympanic membrane ... By help of ear ossicle mallus- incus-stapes get convert into mechanical energy ...

In inner ear it again changes to electric potential by help of endolymph n perilymph fluid movement in organ of corti

It goes to temporal lobe ..

Here,

Ear ossicle and organ of corti act like transducer ...

4) transmission :- it is transfer in simple terms ..

From one point to other .

Like ..maw...maw.. transmitted through Air ...to ear

In ear transmission through ear ossicle...n electric current .

All r example of transmission

5) perception :- ..

It is what you perceive when stimulus is given

Ex. Maw...maw...

One person never heard cat sound ...

His perception to this maw...maw...is it might be some children sound, or lady sound ..

But who has previous store memory of cat sound he immediately recognize or perceived it as cat ...

Perception is different for different person on his previous experience..

Man has rope in his hand ...one person see it as rope (previous experience). Other person see it as snake ( false perception due to mental condition called hallucinations.

Explain the difference between "sensation" and "perception." Be sure to include a discussion of where or how these concepts overlap (if they do overlap) as well as where or how they do not overlap (if they do not overlap). Provide at least two examples to support your discussion.

- The difference between sensation and perception. The difference between bottom-up and top-down processing, this is as important as it can get. Examples of top-down processing related factors such as visual context, expectations effects, regularities in the environment, and the Gestalt rules of perceptual grouping. Examples of depth cues must be familiar and they could be discussed in relation to bottom-up and top-down processing. The role of top-down processing in the hollow-face illusion and the Ames room illusion is important.

Assignment Question Sensation and Perception: Signal Detection Psychologists have always been interested in the relationship between physical stimuli and the cognitive interpretations of the sensations and perceptions these stimuli produce. This field of study is called psychophysics. One of the major contributions of psychophysics is signal detection theory (SDT). The concepts behind SDT had a very practical beginning. They were first developed as a way to help the military pick the best sonar and radar operators during World War II....

What is primary taste sensation, and the major type of receptors. Distinguish between static and dynamic equilibrium. Know major structures involved in each. Know what they monitor. Receptors for hearing are located in the cochlea. What is the function of cochlear hair cells? What membrane layer supports them? Which membrane to the hair cells bend against? Know roles of rods and cones in the eye. Where exactly are they found and in what concentration? What is the significance of the optic...
