Final answer:
The most correct statement regarding Treisman's filter model of attention is that information is selected for further processing based on both physical and semantic relevance. This model posits that while all information is attenuated, some can gain attention through meaning or physical properties, allowing for unattended stimuli to sometimes be processed.
Step-by-step explanation:
The query you have presented pertains to Treisman's filter model of attention. According to Treisman's filter model, which is the most correct? The answer is a) information is selected for further processing based on both physical and semantic relevance. This model, known as the Attenuation Theory, suggests that information is processed at different levels of attenuation and is not entirely blocked or entirely let through. Thus, some information that may not initially seem pertinent can become important if it gains the individual's attention through meaning or physical relevance, such as one's own name being overheard at a noisy party.
On the contrary, an inherent shortcoming of the broadbent's early-selection model was its inability to explain why some unattended stimuli, like the individual's own name, can sometimes break through the attentional barrier and be processed, whether consciously or not, a phenomenon known as the cocktail party effect.
