Consistency in attending aids automatic processing development, even with inconsistent responding. Inconsistent response processes incur costs but do not halt automaticity in task components.

Area of Science:

  • Cognitive Psychology
  • Human Factors
  • Neuroscience

Background:

  • Automatic processing is crucial for efficient cognitive function.
  • Understanding the factors influencing automaticity development is key to optimizing human performance.
  • Task consistency is often considered a prerequisite for automaticity.

Purpose of the Study:

  • To investigate the specific role of consistency in the development of automatic processing.
  • To determine if consistency in all task components is necessary for automaticity.
  • To differentiate the effects of consistent attending versus consistent responding.

Main Methods:

  • Subjects performed a memory search task with varying memory set sizes (two and four items).
  • Attending and responding components were factorially combined as either consistent or inconsistent.

  • Measures included reaction time, P300 latency, and P300 amplitude.

    • Main Results:

    • Automaticity developed with consistent attending, irrespective of response consistency.
    • Inconsistent responding led to increased reaction time and altered P300 measures.
    • These costs associated with inconsistent responding were linked to stimulus evaluation and response processes.

    Conclusions:

    • Total task consistency is not required for automatic processing to develop.
    • Automaticity can emerge in consistent task components even without overall stimulus-response consistency.
    • This highlights the modular nature of automaticity development in complex tasks.
