Changing-state irrelevant speech disrupts visual-verbal but not visual-spatial serial recall

Area of Science:

• Cognitive Psychology
• Auditory Distraction
• Short-Term Memory

Background:

• Jones et al. (1995) proposed an amodal mechanism for serial order representation in short-term memory based on auditory distraction.
• Their findings suggested auditory distraction effects were similar across visual-verbal and visual-spatial tasks.
• The robustness of these findings has been questioned due to a lack of replication.

Purpose of the Study:

• To conduct high-powered replications of Jones et al.'s (1995) Experiment 4.
• To investigate the changing-state effect in auditory distraction across different short-term memory tasks.
• To test the amodal mechanism hypothesis against modular and interference-based accounts.

Main Methods:

• Two experiments were conducted, replicating Jones et al.'s (1995) Experiment 4.
• Experiment 1 used a within-participants design (n=64) without a retention period.
• Experiment 2 used a between-participants design (n=128) with a retention period.

Main Results:

• The changing-state effect was observed in the visual-verbal serial recall task in both experiments.
• The changing-state effect was not observed in the visual-spatial serial recall task in either experiment.
• Results indicated a modality-specific effect of auditory distraction.

Conclusions:

• The findings challenge the notion of a single, amodal mechanism for serial order representation.
• Results support modular and interference-based models of auditory distraction.
• The study highlights differences in how auditory distraction affects visual-verbal versus visual-spatial short-term memory.
