Why does semantic priming effects decay faster with aging?

💡 Explanation

Semantic priming relies on activation spreading: encountering a prime word partially activates related concepts, facilitating recognition of a target word. In aging, inefficient activation spreading weakens these connections, because the activation doesn't reach a sufficient threshold, therefore the effect decays faster, rather than enhanced by neural noise.

• Why does predictive text entry degrade when a writer frequently switches between languages with differing orthographies?
• Why does extracting probabilistic context-free grammars (PCFGs) from a large, automatically parsed corpus for use in a statistical machine translation (SMT) system often lead to suboptimal translation performance?
• A novelist employs a complex, non-linear narrative in which key plot points are revealed through unreliable narrators. Which risk increases as the narrative's ambiguity intensifies?
