The ecology of automaticity: toward establishing the conditions needed to produce automatic processing effects

In the past 15 years, the single term automatic has been applied to a diversity of laboratory phenomena that differ as to the preconditions necessary for their occurrence. Several major strains of automaticity are distinguished, based on the experimental conditions under which they are obtained: preconscious automatic processes, requiring only the proximal stimulus event; postconscious automatic processes, similar to preconscious effects but needing a recent activation or "priming" event for their operation; and goal-dependent automatic processes, which occur only when a specific, intentional processing goal is in place. It is argued that to more accurately specify the conditions under which an automatic effect will occur in the natural environment, greater attention needs to be given to aspects of the experimental paradigm (e.g., subjects' task goal, questionnaire administrations, previous tasks) that might be necessary to produce the effect.
