Pscyhological vs Physiological!

[coolhat]

If psychological relates to the mind and physiological relates to the body-then how is hand tremors a psychological effect of prolonged arousal (as it says in the Grivas Psychology Book)

Hmm, this is relating to sleep deprivation right?
Well if it is in there, i believe it's wrong.
In my notes book, we've written hand tremors under 'physiological'

maybe you looked at it wrong. I've got it right here and it has it under physiological (in grivas). top right hand corner of page 306.

lol dude
hand tremors are 100% definitely Physiological ....
psychological can ONLY ONLY ONLY be associated with cognitive functioning and mind functions , eg emotional responses such as depression

This is for prolonged arousal which is stress.

In the Grivas book hand tremours is listed as a behavioural change under psychological effects of intense/prolonged stress (page 152).

Psychological doesn't necessarily have to be cognitive/mind functions because substance abuse, overeating, undereating, excessive exercise are considered to be a psychological effect of stress. These would go under 'behavioural changes' which is a type of psychological effect of stress (the other two being cognitive and emotional) and it's probably be safer writing these effects instead of hand tremours.

I think it's worth noting the definition of Psychology

Psychology is the scientific study of thoughts, feelings and behaviours.

Next semester, you'll have a entire Area of Study dedicated to learning about behaviour, and in particular, a philosophy of psychology named behaviourism. Many of it's researchers did not believe that you could actually study cognition/mind functions scientifically.

Thankyou minilunchbox for reading my first question correctly. Now to my second point, if that is correct, then shouldn’t hand tremors (a long term effect of sleep deprivation) be psychological NOT physiological? then why does it say in the Grivas Book on page 306 that hand tremors are physiological?

[Glockmeister]

No, because the hand tremors are the result of long-term changes to the body chemistry - I'd imagine it'd be some sort of cortisol release, but I am not 100% sure.
