Age of acquisition effects in recognition without identification tasks

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• The Age of Acquisition (AoA) effect describes faster processing of early-learned words compared to late-learned words.
• This effect is often attributed to developing semantic representations and neural networks over time.
• Recognition Without Identification (RWI) effects have been noted at the perceptual level.

Purpose of the Study:

• To investigate if the AoA effect originates at the perceptual level using the RWI paradigm.
• To determine if RWI and AoA effects interact and where they are localized in the processing stream.

Main Methods:

• 174 participants identified early- and late-acquired picture or word fragments after a study phase.
• Participants rated recognition likelihood for studied and unstudied items, regardless of identification success.
• Two experiments were conducted: one with pictorial stimuli and one with word stimuli.

Main Results:

• Studied items were recognized more accurately than unstudied items, even when unidentified.
• Late-acquired items were recognized more than early-acquired items, irrespective of identification.
• An interaction between RWI and AoA was observed exclusively with pictorial stimuli.

Conclusions:

• The findings suggest that the AoA effect can operate at the perceptual level, particularly for visual stimuli.
• The RWI paradigm provides evidence for perceptual influences on word and picture recognition.
• The interaction in pictorial stimuli indicates a shared perceptual locus for RWI and AoA effects in visual processing.
