Study Notes
Treisman's Attenuation Model
- The attenuator in Treisman's model is a processing unit that weakens the strength of unattended messages.
- The attended message passes through the attenuator with full strength, while the unattended message's signal is weakened.
- Attended messages have a stronger signal than unattended messages.
- The dictionary unit stores words and their associated meanings, thresholds, and other information.
- Treisman's model explains recognition through the dictionary unit, which contains information about words and their meanings.
- The main focus of attention in Treisman's model is on the attended message, which is processed with greater strength and detail.
Dichotic Listening Task
- Participants were instructed to pay attention to one ear's message (attended ear) and ignore the other (unattended ear).
- Participants found it difficult to recall the unattended ear's message, even when it was presented in the same language and by the same speaker.
- Participants were able to demonstrate awareness of the unattended ear's message. For example, they could tell if the speaker's gender changed.
- The findings of the Dichotic Listening Task, where participants demonstrated some awareness of the unattended channel, contradicts Broadbent's Filter Model. Broadbent's model proposed that the unattended message is completely blocked.
