Summary
This study investigates the relationship between two distinct levels of task coordination in multitasking: cognitive task processing modes and behavioral response organization strategies. Previous research had examined individual preferences for serial versus overlapping processing (using the Task Switching with Preview, or TSWP, paradigm) and for blocking, switching, or response grouping strategies (using the Free Concurrent Dual-Tasking, or FCDT, paradigm) separately. The authors aimed to determine if these preferences are linked intra-individually, hypothesizing that individuals preferring overlapping processing would favor switching strategies to exploit time gains, while those preferring serial processing would favor blocking strategies to minimize dual-task demands. The experiment involved 70 participants who performed two simple classification tasks (digit parity and letter vowel/consonant) in both the TSWP and FCDT paradigms. In the TSWP condition, participants followed a prescribed sequence but could use a visible preview of the next task’s stimulus to prepare for switches. In the FCDT condition, participants freely organized their responses to maximize throughput. Researchers analyzed inter-response intervals and error rates to categorize participants into processing modes (serial, semi-overlapping, or overlapping) and response strategies (blocking, switching, or response grouping). The results confirmed the predicted correspondence between processing modes and response strategies. Most participants identified as serial processors in the TSWP paradigm preferred a blocking strategy in the FCDT paradigm, focusing on one task for extended periods before switching. Conversely, overlapping processors predominantly preferred a switching strategy, frequently alternating between tasks. Furthermore, the study found that when an individual’s preferred processing mode and response strategy did not correspond (e.g., a serial processor using a switching strategy), overall multitasking efficiency was significantly lower. This suggests that alignment between cognitive processing style and behavioral organization is crucial for optimal performance. These findings indicate a strong link between how individuals cognitively process concurrent tasks and how they behaviorally organize their responses, likely reflecting a fundamental difference in cognitive control styles (flexible vs. persistent). The study concludes that distinguishing between these two aspects of multitasking is essential for understanding individual differences in performance. Future research should consider both processing modes and response strategies to fully capture the mechanisms underlying multitasking efficiency, as mismatches between preferred cognitive styles and behavioral strategies lead to substantial performance costs.
Key finding
Individuals who prefer overlapping task processing predominantly use a switching response strategy, whereas those who prefer serial processing favor a blocking strategy, and mismatches between these preferences result in reduced multitasking efficiency.
