Visual Working Memory Capacity and Proactive Interference
Author Information
Author(s): Hartshorne Joshua K.
Primary Institution: Harvard University
Hypothesis
The study investigates whether the poor performance of visual working memory is due to an outsized effect of proactive interference.
Conclusion
The study confirms that visual working memory capacity is limited and that proactive interference has a significant but not overwhelming effect on capacity estimates.
Supporting Evidence
- Visual working memory capacity is significantly affected by proactive interference.
- Measured visual working memory capacity declines by about 12% due to proactive interference.
- Item-specific proactive interference lasts across several trials.
Takeaway
This study shows that our ability to remember visual information is not very good, and things we saw before can make it even harder to remember new things.
Methodology
Participants completed a series of visual working memory tasks in both laboratory and online settings to measure the effects of proactive interference.
Potential Biases
Potential biases may arise from the specific participant demographics and the nature of the tasks used.
Limitations
The study's findings may not generalize beyond the specific types of visual stimuli used.
Participant Demographics
Participants were volunteers from Harvard University and the surrounding community, aged 18-40, with normal or corrected-to-normal vision.
