The label-feedback effect is influenced by target category in visual search.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• The label-feedback hypothesis suggests language influences visual processing.
• Auditory or visual target names (labels) can speed up visual search.
• Previous studies primarily used basic-level target names.

Purpose of the Study:

• To investigate the effect of multimodal audio-visual (AV) labels on visual search.
• To compare AV labels with unimodal (audio, visual) and multimodal noise-visual (NV) controls.
• To examine if the label-feedback effect extends to superordinate category labels and is modulated by category structure.

Main Methods:

• Participants performed a visual search task using superordinate category labels as cues.
• Label conditions included audio+visual (AV), noise+visual (NV), audio (A), and visual (V).
• Target items belonged to categories: garments, improper weapons (ad hoc), and proper weapons.

Main Results:

• Overall facilitation in visual search performance was observed in the AV condition compared to the NV condition.
• This facilitation was driven by the garments and proper weapons categories, not improper weapons.
• The label-feedback effect was confirmed for superordinate labels and modulated by category structure.

Conclusions:

• The label-feedback effect is not solely due to multimodal stimulation and extends to superordinate labels.
• The beneficial effect of AV labels requires "up-regulation" of the label, which is hindered for ad hoc categories.
• Category structure, specifically the ad hoc nature of improper weapons, influences the label-feedback effect.
