The effects of sensorimotor and linguistic information on the basic-level advantage.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• The basic-level advantage is a well-established phenomenon in human categorization.
• Traditional theories posit basic-level categories as the most informative entry point in semantic memory.
• Recent linguistic-simulation accounts highlight the roles of sensorimotor and linguistic distributional information in conceptual processing.

Purpose of the Study:

• To investigate whether sensorimotor and linguistic distance measures contribute to the basic-level advantage.
• To examine the predictive power of these novel measures in categorization tasks.
• To reconcile traditional categorization theories with newer sensorimotor-linguistic models.

Main Methods:

• Four preregistered word-to-picture categorization studies were conducted.
• Measures of sensorimotor experience overlap between category and member concepts were used.
• Linguistic distributional information and image label production frequency were analyzed.
• Reaction times (RT) and accuracy were recorded as key dependent variables.

Main Results:

• Sensorimotor experience overlap predicted RT and accuracy comparably to traditional taxonomic levels.
• Linguistic distributional information captured graded category structure effects beyond typicality ratings.
• Linguistic information predicted RT and accuracy beyond sensorimotor information when image label production frequency was considered.

Conclusions:

• Sensorimotor and linguistic information are crucial for understanding categorization behavior.
• These findings support and extend sensorimotor-linguistic theories of the conceptual system.
• The study provides a more nuanced understanding of how conceptual knowledge is represented and accessed.
