Hypothesis
The quality of decision-making in cognitive tasks is unaffected by concurrent task interference.
Conclusion
The study found that while response times are delayed during dual-task execution, the error rates remain unaffected.
Supporting Evidence
- Dual-task interference significantly affects response times but not error rates.
- The internal Weber fraction remains consistent regardless of task order.
- Participants were trained extensively before the experiment to ensure proper performance.
Takeaway
When doing two tasks at once, it takes longer to respond, but you don't make more mistakes.
Methodology
Participants performed two non-symbolic comparison tasks (number comparison and tone discrimination) with varying stimulus onset asynchrony (SOA).
Limitations
The study involved a limited sample size and focused only on specific types of cognitive tasks.
Participant Demographics
16 participants (6 males, average age 25±4), all native Spanish speakers.
