Memory Concepts Matching Solution

This question requires matching key memory concepts from List-I with their corresponding explanations in List-II.

Detailed Matching:

• Engram (a): This refers to the physical location and changes in the brain that represent the stored memory. It aligns with the explanation of "The physical trace of memory in the brain" (iv).
• Explicit memory (b): This type of memory involves conscious thought and the intentional recall of factual information and events. It matches the explanation "Engaging in conscious recollection" (i).
• Long-term potentiation (c): This is a biological process involving the strengthening of synaptic connections between neurons through repeated stimulation, leading to lasting changes. It corresponds to "Changes in dendrites and in the sensitivity of synapse through repeated stimulation" (ii).
• Implicit memory (d): This memory type is unconscious and influences behavior or performance without conscious awareness. It fits the explanation "Recollecting something without being consciously aware" (iii).

Correct Combination:

Based on the above analysis, the correct pairings are:

• (a) - (iv)
• (b) - (i)
• (c) - (ii)
• (d) - (iii)

This combination matches Option 2.
