28: OCR Sleep & Dreaming - Activation synthesis theory

Which stage of sleep does the activation synthesis theory focus on?

• Stage 1

• Stage 2

• Stage 3

• Stage 4

• REM

The theory says that powerful electrical signals come from which part of the brain?

Which part of the brain contains the pons?

• brainstem

• cerebral cortex

• frontal lobe

• limbic system

Electrical signals pass from the pons to where?

• brainstem

• cerebral cortex

• frontal lobe

• limbic system

Electrical signals pass from the limbic system to where?

• brainstem

• cerebral cortex

• frontal lobe

• pons

Which statement is true?

• The AST suggests dreams are random because the cerebral cortex is trying to add meaning to random brain activity.

• The AST suggests dreams are random because the limbic system is trying to add meaning to random brain activity.

"...because it only focuses on random electrical brain activity and ignores other factors that influence dreaming."

Which evaluation point does this match best?

• The theory is reductionist...

• There is evidence to contradict the theory...

• There are alternative theories...

• The theory is not very useful...

"...for example, people with damaged brainstems still dream."

Which evaluation point does this match best?

• The theory is reductionist...

• There is evidence to contradict the theory...

• There are alternative theories...

• The theory isn't very useful...

"...for example, we don't only dream during REM sleep, suggesting other factors than brain activity in this stage cause dreaming."

Click the correct 'journey' of electrical activity during REM sleep, according to the theory.

• cerebral cortex to limbic system to pons

• limbic system to pons to cerebral cortex

• pons to cerebral cortex to limbic system

• pons to limbic system to cerebral cortex
