Argentinean Psycholinguistic Picture Naming Test in color

Area of Science:

• Neuropsychology
• Psycholinguistics
• Cognitive Science

Background:

• Color diagnosticity influences object recall speed in naming tasks.
• Existing naming tests in Argentina lack specific psycholinguistic norms and color utilization.
• The Argentinean Psycholinguistic Picture Naming Test in color (PAPDIC) was developed to address these limitations.

Purpose of the Study:

• To introduce and validate the Argentinean Psycholinguistic Picture Naming Test in color (PAPDIC).
• To assess the psychometric properties of the PAPDIC in diverse patient populations and healthy controls.
• To establish PAPDIC as a reliable tool for identifying anomia in clinical settings.

Main Methods:

• Psychometric analyses including convergent and criteria validity, and reliability testing.
• Correlational analysis with the brief Boston Naming Test.
• Contrasted groups analysis and Receiver Operating Characteristic (ROC) curve analysis.

Main Results:

• Strong evidence of convergent validity (r=0.871, p < .001).
• Significant criteria validity demonstrated through contrasted groups analysis (t=4.059, p < .001) and ROC analysis (AUC = 0.993).
• High internal consistency reliability (KR20 = 0.905).

Conclusions:

• The PAPDIC is a psychometrically sound and promising tool for color naming assessment.
• PAPDIC can be effectively applied in clinical neuropsychology to diagnose anomia.
• The test offers advantages over existing naming assessments in Argentina.
