Attention capture by own name decreases with speech compression

Area of Science:

• Cognitive Psychology
• Auditory Neuroscience

Background:

• Personally relevant auditory stimuli, like one's own name, can involuntarily capture attention.
• Understanding how speech compression affects attention capture is crucial for auditory distraction research.

Purpose of the Study:

• To investigate the attention-capturing potential of the listener's own name in normal and time-compressed speech.
• To determine how different levels of speech compression influence the degree of attention capture by personally relevant auditory stimuli.

Main Methods:

• Two experiments were conducted using a visual word categorization task with spoken names as auditory distractors.
• Experiment 1 used normal speech, while Experiment 2 used time-compressed speech at three different compression levels.
• Participant performance was measured by reaction times in the categorization task and detection accuracy for names.

Main Results:

• Participants were slower at categorizing visual words when their own name was presented as a distractor compared to other names.
• Attention capture by the listener's own name was observed in both normal and time-compressed speech.
• The degree of attention capture by time-compressed speech varied with compression level, being strongest with slight compression and weakest with intense compression.

Conclusions:

• Personally relevant speech, such as one's own name, can capture attention even when unattended.
• The effectiveness of attention capture by time-compressed speech is modulated by the degree of compression.
• Findings provide partial support for the duplex-mechanism account of auditory distraction and highlight practical implications for understanding attention in noisy environments.
