Questions: Which of the following statements is true according to activation-synthesis theory? Multiple Choice Dreaming occurs when the thalamus synthesizes neural signals generated from activity in the lower part of the brain. It proposes that one can understand dreaming by applying the same cognitive concepts used in studying the waking mind. It rests on the idea that dreams are essentially subconscious cognitive processing. Dreams result from the brain's attempts to find logic in random brain activity that occurs during sleep.

The answer is the last one: Dreams result from the brain's attempts to find logic in random brain activity that occurs during sleep.

Explanation for each option:

1. Dreaming occurs when the thalamus synthesizes neural signals generated from activity in the lower part of the brain.

   • This statement is not accurate according to the activation-synthesis theory. The theory primarily involves the brainstem and the cerebral cortex, not specifically the thalamus.

2. It proposes that one can understand dreaming by applying the same cognitive concepts used in studying the waking mind.

   • This statement aligns more with cognitive theories of dreaming, not the activation-synthesis theory. Cognitive theories focus on the continuity between waking and dreaming cognition.

3. It rests on the idea that dreams are essentially subconscious cognitive processing.

   • This statement is more aligned with psychoanalytic or cognitive theories of dreaming, which emphasize subconscious processing and cognitive functions.

4. Dreams result from the brain's attempts to find logic in random brain activity that occurs during sleep.

   • This is the correct statement according to the activation-synthesis theory. The theory, proposed by J. Allan Hobson and Robert McCarley, suggests that dreams are the brain's way of making sense of random neural activity during REM sleep.

Summary: The activation-synthesis theory posits that dreams are the brain's attempt to create a coherent narrative from random neural activity that occurs during sleep. Therefore, the correct statement is that dreams result from the brain's attempts to find logic in random brain activity that occurs during sleep.
