Question

What is the primary criticism of Deutsch and Deutsch&#x27;s late selection theory of attention?

Accepted Answer

The primary criticism of Deutsch and Deutsch&#x27;s late selection theory of attention is that it posits that all stimuli are fully processed for meaning before attention selects which stimuli to respond to, which seems cognitively inefficient and contradicts empirical evidence. The theory suggests that the brain processes all incoming information to a deep semantic level, regardless of whether it is attended to or not. Then, a later selection stage determines which information is consciously recognized and acted upon. Critics argue that this would require significant cognitive resources and energy to process irrelevant information fully. It&#x27;s generally accepted that some filtering or attenuation of unattended information occurs earlier in the processing stream to prevent cognitive overload. Empirical studies also suggest that semantic processing of unattended information is limited and depends on factors such as task demands and stimulus salience, rather than a universal full processing as proposed by Deutsch and Deutsch. Therefore, the late selection theory is seen as less plausible due to its inefficiency and lack of strong empirical support for complete semantic processing of all stimuli.
