Masked transposition priming effects are observed in Korean in the same-different task.

Area of Science:

• Cognitive Psychology
• Linguistics
• Neuroscience

Background:

• Readers of Korean Hangul exhibit precise orthographic coding.
• Previous research indicates Hangul word identification is not facilitated by transposed primes, unlike many other languages.
• The same-different task is believed to reflect pre-lexical orthographic representations.

Purpose of the Study:

• To investigate if precise orthographic coding in Hangul readers is evident in the same-different task.
• To determine if masked transposed-letter or transposed-syllable-block primes influence same-different judgments for Hangul stimuli.
• To explore whether observed differences in orthographic coding across writing systems stem from task demands or representational properties.

Main Methods:

• Two experiments were conducted using a same-different task paradigm.
• Experiment 1 utilized masked transposed-letter primes.
• Experiment 2 employed masked transposed-syllable-block primes.

Main Results:

• Significant transposition effects were observed in both Experiment 1 and Experiment 2.
• These findings contrast with previous lexical decision tasks using Hangul.
• Evidence suggests precise orthographic coding is detectable in the same-different task for Hangul.

Conclusions:

• The study provides evidence for precise orthographic coding in Hangul readers within the same-different task.
• Apparent cross-linguistic differences in orthographic coding precision may be influenced by the demands of word identification processes.
• Writing system properties might not solely dictate the precision of orthographic representations.
