THE EXAM

[jess3254]

I still think it's ridiculous if PET is the answer

[kat148]

OMG i dont how i went but i did the biggest stupid mistake. did the question about mullyer illusion say that we have to mention the gestalt principle...... 

no

Q.10b) Describe the Muller-Lyer illusion and give one explanation of how this illusion works

[jessek]

"when this substance enters the bloodstream it travels to the brain"

although Grivas has been wrong on many occasions, i'm not one to argue with him.



and yeah probably, the gestalt principle of closure is used in ross day's theory of perceptual compromise.

[shandi]

Err what do Gestalt principles have to do with the Muller Lyer? We had to discuss the theories. Ie: Carptenered World Hypothesis or the one about Perceptual Compromise.

[bellsy104]

The most correct answer to the function question involving the lady with a pacemaker was PET imo.
A - CT - shows structure, not function..
B- PET - said she wanted to 'avoid' an injection

C or D would rip her pacemaker out?

[jessek]

carptenered world?
perceptual compromise occurs because we receive 3 conflicting pieces of information
1. the length of the two main lines
2. the total length of each figure
and 3. the total area of the space we see between the main line, and the lines on the end (that we see because of the gestalt principle of closure)

[shandi]

When we use familiar architectural features to interpret the illusion. So we see the arrow heads as the leading vertical edge of a building's outer wall, and the feather fail as the inside corner of a room (so it is percieved as further away).

[jessek]

yeah, gregory's theory. that explanation has been proved incorrect though.
the muller-lyer has been test with people living in africa, who have buildings with no right angles, and the illusion stilll works.
plus, the feathertails and arrowheads can be substituted with other shapes and it still works.

[Glockmeister]

the muller-lyer has been test with people living in africa, who have buildings with no right angles, and the illusion stilll works.

You're sure about that? My textbook says the complete opposite.

[jessek]

it's not an illusion if it doesn't occur consistently.
it always works, i am sure.

[vexx]

it is true that an illusion works consistenly regarldess of if the effect is known or not, but the effect is increased if we have prior experience to elements of the illusion: for example we know that rooms are rectangular which increases the effect of the ames room, but this does does not mean that it will not work for other people as there are other aspects like the monocular peephole,ect.

[Glockmeister]

I got the quote from my textbook

"when people from other cultures who live in more rounded environments are shown the Muller-Lyer stimuli, they are more likely to correctly perceive the lines as equal in length" (Segall et al., 1966, as cited in Passer & Smith, 2008, p. 165).

To all those who need feedback, my psych teacher went through all answers :S
first stage is reception, not selection..
it's most likely to be pet and fmri cant use pacemaker regardless of what, it says in psych notes
also we can't use convergence for ames because it clearly says the peephole removes all chance of monocular cues
the explanation about the cars that was made for the prvious person is correct .. perfectly well done hehe.
and muller lyer you can talk about apparent distant theory - the fishtails make it appear FURTHER away although they BOTH produce same retinal image.
these were all said by the psych teacher soo ??
do u guys rkn the state average for a+ will be lower than last yr

you mean binocular cues, peephole only allows monocular depth cues to be used, but yes it is convergence.

Okay Question 13. PET IS NOT THE ANSWER. None of htem seem plausible to put. As already discussed in this forum.. But CAT is the answer.

FMRI AND MRI are wrong.. for obvious reasons.. and so it leaves PET AND CAT.. now PET is functional and CAT is structural. Now. The reason why PET is considered invasive, is not becuase of hte injection, because cat as an injeciton. it's because the radioactive glucose going into the blood stream. So yes, u can swallow glucose shit.. but its still invasive because thats whats being put into ur body. I thinkthe question is very stupid, and it will be taken off..

Anotehr thing is other sources say CATs show function, but thats stupid because the text book that we have says its only structural. Furthermore, i was tlaking to a mates and two of them have mum's who are nurses, who said that they'd do CAT in that circumstance, and definetly not MRI AND FMRI.. but yeh apparnetly CAT is the answer.
