Can we use Brightness,shape, size, orientation in our definitions of constancies

[kazzacae]

confused??? can we use the words brightness in out definitions for brightness constancy
e.g
brightness constancy refers to the tendency to perceive a stimulus as maintaining brightness despite changes in the brightness of the image projected on the retina??

[lolbox]

I don't see why not. I am using those words in my definitions. The notes I'm using to study has the same words in the definition.

[Spreadbury]

I did the 2008 VCAA exam today and one of the questions asked to explain orientation constancy. in the examiner's report is specifically stated that "orientation" could not be used in the definition. their answer used "angle" or "position" instead.

Heres a good question:

How can perception be both psychological and physiological?

[Glockmeister]

Physiological - processing of visual information by various cortical processes.

Psychological - processing of that visual information to give meaning to that information.

The most important function of the corpus callosum is to
A. regulate control of heart rate and blood pressure.
B. regulate hormone production.
C. transfer sensory and motor information between the hemispheres.
D. transfer language information from Broca’s area to Wernicke’s area.

The answer is C but I thought the motor cortex does not use the corpus callosum, as said by Grivas(pg.91) and Glockmeister

WTFFFFFFF?

Sometimes there might be flaws in the answers but you can't keep looking for deeper meanings. It will cost you dearly in the exam. Just cancel out the distractors and you've got your answer. Options A,B and D are obviously wrong so just go with C. In Grivas it just talks about the motor cortex message not needing to use the corpus callosum for the left hand. Maybe for other motor functions it does. I wouldn't worry about this little technicality.

The motor cortex doesn't use the corpus callosum when sending information to a body part (the left hand), but it would still need to use it to send motor information between hemispheres (left motor cortex -> right motor cortex) which is why N.G. is unable to say what she saw because the sensory/visual information couldn't cross hemispheres.

Yeah I know, I got the right answer, but still its annoying

It's a bad answer I know. Did that come out of a VCAA paper? If it didn't, then I wouldn't worry too much about it.

guys-back to the point-does anyone actually know if can we use the words brightness, shape, size, orientation in our definitions of constancies? as in the vcaa 08 examiner's report it specifically stated that "orientation" could not be used in the definition. their answer used "angle" or "position" instead.

[Visionz]

I lost a mark in my VP sac because I said orientation in the definition. I think I did read one assessor report that said dont mention the word in the definition.

To be safe just use a synonym.

Orientation - position
Shape - Form
Size - Dimensions
Brightness - level of light reflected

thanks a lot!

VCAA 05'
Studies of people who are suffering long-term stress indicate that they
A. show some ill-effects early on but recover quickly.
B. recover gradually from any ill-effects but do not have lasting effects of the stress.
C. are more likely to have ulcers than problems with high blood pressure.
D. are more likely to show poor health later in life.

How am I supposed to differentiate btw C and D? D is the answer, but how would I of known that?

D - Because a cause-effect relationship between stress and those diseases has yet to be determined. Pretty straight forward.
