Hmm I said exhaustion. She got the flu and then she had to take a week off work so I thought theat that was a key indicator .. ahh I hope they allow both !
also what did people say for the ames room question ? The one about the father shrinking and the peephole?
Hmm I also said A (frontal lobe) for the first multiple choice question, because how are only 75% of the brains neurons in the cerebral cortex? where is the other 25%? The corpus callosum is made of nerve fibres right?

Hmm, with the Ames room: It is a distorted trapezium shaped room (which appears to be "normal", i.e. rectangular - when viewed monocularly). The left hand corner (where father was pushed by witch) was double the distance than the right hand corner (witch with children) from the viewer/camera, the retinal image of him moving from the right to left halves in size, as it viewed through a single peep hole which only allows monocular depth cues. Hence, shape constancy is maintained at cost of size constancy. Thus, the father appears to "shrink".

the other 25% is below the cerebral cortex... the cerebral cortex is only a few millimetres thick (i should know how many haha )

how could 75% of the neurons be in the frontal lobe? does that mean 25% is shared between occipital, temporal and parietal?

For the gestals principle the first one can the answer be Figure-ground as well?
Because I had proximity in my mind but I could explain the other better.
And the second one I put closure

yeah figure ground was applied in both, figure ground is applied in like everything
so yeah it would have been acceptable

wasn't it 70% of neurons in the cns? i cant remember the question but i remember initally thinking frontal lobe then i saw the functioning but when seeing the 70% thinking the cerebral cortex.
the ames room question i though was strange and gave too much detail about the dad and the witch when it was not needed. i wrote somthing about him getting smalller/larger(cant remember which) because he was pushed and then i described the features of the ames room

Oh thank god B)
Explaining the circle was tricky because the little circles made up a picture of a circle, bigger circle. I hope I clarified myself in the answer...

[babygurl]

I did promixity for the first one, and closure for the second

[littlebecc]

what the fuck was with the goggles question :\

[Hongld]

I did promixity for the first one, and closure for the second

Still correct ^_^

[psych93]

Haha good point about 25% being shared among the occiptial, parietal and temporal. I changed that question in the last minute ... how annoying !!
Do you think you would have to say all those things about the Ames Room to get the full marks?
Because I only said about the distance of the left corner being twice as far away and therefore when we use monocular vision we cant perceive the depth which causes the illusion of him shrinking
I forgot to say anything about the trapeziodal shaped room or shape/size constancy

i used proximity and closure

[babygurl]

Lol lol I know, the goggles question was worded so weirdly! lol just had to relate it back to absolute threshold when it asked for the example.

[babygurl]

Hmm not sure, depends how many marks the ames room question was worth. I really wish someone could upload the exam!

[Hongld]

I didnt know the the hell the goggle questions wanted from me O_o
