Domain-specific cognitive flexibility: Shift-readiness adaptations for task- and attention-switching are...

Area of Science:

• Cognitive psychology
• Neuroscience
• Human behavior

Background:

• Adaptive behavior requires cognitive flexibility for competing goals in dynamic environments.
• Cognitive flexibility encompasses task switching and attention shifting, which can be strategically modulated based on task demands.
• Previous research has studied task-switching and attention-shifting independently, showing context-specific adaptations.

Purpose of the Study:

• To investigate potential transfer of cognitive flexibility adaptations between task switching and attention shifting domains.
• To determine if manipulating switch/shift frequencies in one domain affects flexibility in the other when performed concurrently.
• To explore whether probabilistic learning and adjustments for attention and task switches occur independently.

Main Methods:

• A novel experimental paradigm combining concurrent cued task switching and attentional shifting was implemented.
• Five experiments orthogonally manipulated the frequency of task-switches or attention-shifts across blocks of trials.
• Performance costs associated with task switching and attention shifting were measured under varying frequency conditions.

Main Results:

• Performance costs of attentional shifts remained constant across task-switch biased contexts, despite task-switch cost adjustments.
• Costs of switching between tasks remained constant across blocks with varied attention-shift frequency, despite attention-shift cost adaptations.
• Adaptations in cognitive flexibility for task switching and attention shifting appear to occur independently.

Conclusions:

• Cognitive flexibility adaptations to contextual demands in task switching and attention shifting do not transfer between domains.
• Probabilistic learning and adjustments for attention shifts and task switches operate independently.
• This suggests distinct neural or cognitive mechanisms underlying flexibility in these two domains.
