[Psychological study of parameter selection for Chinese speech warning]
Summary
Optimal Chinese speech warning parameters were identified to enhance cognitive performance in healthy males. These findings provide an ergonomic basis for designing effective warning systems in space vehicles.
Area of Science:
- Human-Computer Interaction
- Cognitive Psychology
- Aerospace Ergonomics
Background:
- Effective auditory warning systems are crucial for manned space missions.
- Understanding the cognitive impact of speech warning parameters is essential for astronaut safety and performance.
- Previous research has not fully optimized Chinese speech warning parameters for cognitive properties.
Purpose of the Study:
- To investigate the effects of Chinese speech warning parameters on cognitive properties.
- To determine optimal parameters for Chinese speech warnings based on cognitive performance.
- To establish an objective ergonomic basis for designing speech warning systems in manned spacecraft.
Main Methods:
- Experiments were conducted with 20 healthy male participants.
- Cognitive properties were assessed in relation to various speech warning parameters.
- Sensation-reaction time was measured to evaluate cognitive responses.
Main Results:
- Optimal prewarning sound duration: 0.35–0.55 seconds.
- Optimal prewarning interval: 0.3–0.4 seconds.
- Optimal interval between sentences: 0.3–0.4 seconds.
- Optimal warning sentence length: 7 words or fewer.
Conclusions:
- The study identified specific, optimal parameters for Chinese speech warnings.
- These parameters enhance cognitive properties and are based on space ergonomics.
- The findings provide a criterion for evaluating and designing speech warning systems for manned space vehicles.
