Evaluate Crick and Mitchison's (1986) Reorganisational theory of dreaming.
Worked Solution & Example Answer:Evaluate Crick and Mitchison's (1986) Reorganisational theory of dreaming. - Scottish Highers Psychology - Question b - 2022
Step 1
Strengths of Crick and Mitchison's Theory
Answer
One of the main strengths of Crick and Mitchison's (1986) theory is its suggestion that dreaming serves a vital cognitive function, particularly in the reorganization of memories. This idea implies that during REM sleep, the brain processes and consolidates experiences from the day, allowing for enhanced problem-solving abilities and emotional regulation. Additionally, the theory is supported by findings that learning can occur during sleep, suggesting that the brain is active and engaged even when we are not consciously aware.
Step 2
Weaknesses of Crick and Mitchison's Theory
Answer
However, there are noteworthy weaknesses in this theory. Critics argue that the claim that 'reverse learning' occurs during REM sleep lacks strong empirical evidence. The idea of 'unlearning' seems hypothetical and may not accurately reflect the complexities of memory processing. Furthermore, while the theory posits that REM sleep is crucial for cognitive functioning, the exact mechanisms and dynamics of how dreams contribute to memory reconciliation remain poorly understood.
Step 3
Research Evidence Related to the Theory
Answer
Some studies support the notion that REM sleep is correlated with enhanced memory retention. For instance, research has shown that subjects who experience more REM sleep tend to perform better on tasks requiring recall. Nevertheless, further research is required to establish a direct causative relationship between dreaming and memory consolidation, thereby validating Crick and Mitchison's assertions.
