10 Questions
According to Treisman's attenuation model of attention, how does attention work?
Like an amplifier that selectively enhances some information
What key aspect of Broadbent's Filter Model of Attention is refuted by the Dichotic Listening Task results?
Content recall of unattended information
How is the process of attention described in Treisman's attenuation model different from Broadbent's Filter Model?
Treisman's model focuses on selective enhancement instead of filtering.
What role does the attenuation process play in Treisman's model of attention?
It selectively weakens unimportant information.
Why do the results of the Dichotic Listening Task contradict Broadbent's Filter Model?
They show that participants are unaware of unattended information.
According to Treisman's attenuation model of attention, what is the role of the attenuator?
Decrease the strength of the unattended message
How does the quality of the signal impact recognition in Treisman's model?
Stronger signals are more likely to be recognized
Why do some parts of the message delivered to the unattended ear get recalled based on Treisman's model?
Due to the lower recognition threshold of some words
What happens to the strength of the unattended message as it passes through Treisman's attenuator?
It decreases
How does recognition in Treisman's model depend on the familiarity and relevance of words?
Recognition depends on how familiar and relevant words are to the participant
Study Notes
Attention Models
- Treisman's attenuation model of attention describes attention as a process where multiple messages are processed in parallel, with the strength of the unattended message being reduced (attenuated) by an attenuator.
Critique of Broadbent's Filter Model
- The Dichotic Listening Task results refute Broadbent's Filter Model, which suggests that unattended messages are completely filtered out and not processed.
- This is because the task shows that some parts of the unattended message can still be recalled, contradicting the idea of complete filtering.
Comparison of Attention Models
- In contrast to Broadbent's Filter Model, Treisman's attenuation model allows for some processing of unattended messages, albeit with reduced strength.
- The attenuator in Treisman's model reduces the strength of the unattended message, but does not completely eliminate it.
Attenuation Process
- The attenuation process in Treisman's model reduces the strength of the unattended message, making it less likely to be recognized.
- The quality of the signal impacts recognition in Treisman's model, with stronger signals being more likely to be recognized.
Recognition and Recall
- Recognition in Treisman's model depends on the familiarity and relevance of words, with more familiar and relevant words being more likely to be recognized.
- Some parts of the unattended message get recalled because they are strong enough to overcome the attenuation process, particularly if they are familiar or relevant.
Attenuator's Role
- The attenuator in Treisman's model plays a crucial role in reducing the strength of the unattended message, making it less likely to be recognized.
Learn about Treisman's attenuation model of attention and Broadbent's Filter Model of Attention. Understand the process of focusing on a subset of information and selecting some information for further processing.
