Attentional decoupling while pursuing intentions: a form of mind wandering?

Area of Science:

• Cognitive Psychology
• Attention Studies
• Goal Management

Background:

• Disengaging from primary tasks can negatively impact performance.
• However, attentional shifts may be constructive if they serve future goals.
• Previous research (Cohen et al., 2008) explored intention effects on attention.

Purpose of the Study:

• To investigate how cognitive load of postponed intentions affects attention to an ongoing task.
• To replicate and extend findings on cognitive load and attentional flexibility.
• To understand the conditions under which attentional decoupling occurs.

Main Methods:

• Participants completed a lexical decision task (LDT) classifying letter strings.
• A postponed intention condition required encoding a future response cue.
• Cognitive load was manipulated, and reaction times on the LDT were measured.

Main Results:

• Replicated Cohen et al. (2008) findings on attentional flexibility.
• Reaction time costs occurred only under high cognitive load and for word trials.
• No performance decrements were observed for non-word trials.

Conclusions:

• Individuals flexibly manage attention based on cognitive load and goal relevance.
• High cognitive load and goal-relevant stimuli can disrupt ongoing task performance.
• Decoupling may be initiated by high cognitive load with postponed goals and relevant external stimuli.
