ND250 Index: ERP Data on Visual-Orthographic Familiarity Effect in Chinese Components

A 182.3 KB Excel dataset from figshare, last updated in May 2026, authored by Ziyi Huang. It contains event-related potential (ERP) data recorded during an implicit reading task using Chinese components as stimuli. The data supports research on the neural basis of the ND250 ERP component in visual word recognition.

Use Cases

• Test the Interactive Account's prediction error hypothesis based on ERP responses to Chinese components.
• Investigate visual-form frequency effects in early word recognition based on the ND250 component.
• Compare neural responses to familiar versus unfamiliar orthographic stimuli under implicit task conditions.
• Analyze the dissociation between visual, phonological, and semantic processing in reading.

Strengths

• Data is shared under a permissive CC-BY-4.0 license.
• The study design isolates visual-form frequency from phonological and semantic associations, a specific methodological strength.
• The dataset is focused on a specific ERP component (ND250) and cognitive process.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (182.3 KB), indicating a limited scope.
