Visual Word Segmentation Cues in Tibetan Reading: Comparing Dictionary-Based and Psychological Word Segmentation

Area of Science:

• Cognitive Science
• Linguistics
• Human-Computer Interaction

Background:

• Tibetan script lacks inherent word boundaries, posing challenges for reading.
• Understanding visual segmentation cues is crucial for optimizing Tibetan text presentation and reading efficiency.

Purpose of the Study:

• To investigate the impact of dictionary-based and psychological word segmentation cues on Tibetan reading and lexical recognition.
• To compare the effectiveness of spaces versus color alternation as segmentation cues.

Main Methods:

• Eye-tracking technology was used to monitor reading patterns.
• A 2x3 experimental design compared six conditions involving normal sentences, dictionary segmentation (spaces), psychological segmentation (spaces), and color alternation variations.

Main Results:

• Word segmentation using spaces (both dictionary and psychological) significantly improved reading efficiency and lexical recognition.
• Color alternation did not yield significant facilitative effects.
• Psychological and dictionary segmentation performed similarly, with slight variations in specific reading metrics.

Conclusions:

• Spaces serve as effective visual cues for word segmentation in Tibetan reading.
• Tibetan reading involves complex cognitive processes that may not rely on consistent basic units across different processing levels.
• Findings inform the design of Tibetan digital text for improved readability.
