Final answer:
Treisman's dual-filter model of attention involves both early and late selection of attended information and is supported by evidence. The model also includes the concept of limited capacity of attention.
Step-by-step explanation:
Treisman's dual-filter model of attention suggests that there are two stages of information processing in selective attention. The early stage involves filtering out irrelevant information, while the late stage involves selecting the relevant information for further processing. The model proposes that both early and late stages of selection occur based on the characteristics of the attended information. This serves as evidence for Treisman's model and contrasts with Broadbent's filter model, which only implies early selection of attended information. Treisman's model also incorporates the concept of limited capacity of attention, implying that the amount of information that can be attended to is limited.
