Questions: Which of the following is NOT an effect of sleep deprivation? Multiple Choice Increased long-term memory formation lowered anger threshold Increased Irritability reduced motivation

The answer is the first one: Increased long-term memory formation.

Explanation for each option:

1. Increased long-term memory formation: This is incorrect because sleep deprivation generally impairs memory formation and cognitive functions. Adequate sleep is crucial for the consolidation of long-term memories.
2. Lowered anger threshold: This is correct because sleep deprivation can lead to increased emotional reactivity, including a lowered threshold for anger.
3. Increased Irritability: This is correct because one of the well-documented effects of sleep deprivation is increased irritability and mood swings.
4. Reduced motivation: This is correct because sleep deprivation often results in decreased motivation and energy levels, making it harder to engage in tasks and activities.

Summary: Sleep deprivation does not lead to increased long-term memory formation; in fact, it typically impairs memory and cognitive functions. The other options are all known effects of sleep deprivation.
