Korean words can be both adjectives and verbs. This study shows zero derivation, where a hidden morpheme creates the verb from the adjective, impacting real-time word processing.
Area of Science:
- Linguistics
- Psycholinguistics
- Cognitive Science
Background:
- Korean adjectives like 'balgda' (bright) and 'gilda' (long) function as verbs, posing a challenge for lexical categorization.
- Linguistic debate exists on whether these words have separate entries or share a single entry with zero derivation.
Purpose of the Study:
- To investigate the real-time processing of Korean categorially ambiguous words.
- To determine if zero derivation is involved and its effect on lexical access.
Main Methods:
- A real-time experiment was conducted to analyze word processing.
- Focus on the cognitive mechanisms underlying the recognition of base adjectives and derived verbs.
Main Results:
- Evidence suggests readers identify the base adjective first.
- A covert category-changing morpheme is applied in real-time to derive the verb form.
- This process influences how words are processed during sentence comprehension.
Conclusions:
- The study provides evidence for the zero derivation of Korean ambiguous adjectives and verbs.
- Findings support the role of covert structure in lexical access across languages.

Parameters Affecting Nonlinear Elimination: Zero-Order Input, First-Order Absorption and Two-Compartment Model
When a drug is administered through a constant intravenous infusion and eliminated via nonlinear pharmacokinetics, it follows zero-order input. For example, oral drugs undergo first-order absorption upon administration and are eliminated through nonlinear pharmacokinetics.

Drug clearance depends on the rate of drug elimination and its plasma concentration. Another important parameter is a drug's half-life, which is the time required for its concentration to decrease by half. In most cases, drug clearance follows first-order...
