Summary
Accuracy significantly impacts the intelligibility of educational interpreters using Signing Exact English (SEE). Higher accuracy and optimal lag times improve message comprehension for deaf students.
Area of Science:
- Linguistics
- Education
- Audiology
Background:
- Educational interpreters play a crucial role in deaf education.
- Previous research in this series examined access for students using interpreters.
- The intelligibility of Signing Exact English (SEE) by interpreters requires further investigation.
Purpose of the Study:
- To evaluate the intelligibility of transliterated messages produced by interpreters using Signing Exact English (SEE).
- To determine the impact of accuracy and lag time on the intelligibility of SEE transliterations.
- To identify factors contributing to the variability in interpreter intelligibility.
Main Methods:
- Eight expert receivers of SEE evaluated transliterated messages.
- Messages varied in accuracy and lag time.
- Intelligibility was measured using standardized tests.
Main Results:
- Interpreter accuracy significantly positively affected intelligibility.
- Overall intelligibility (69%) surpassed average accuracy (58%).
- Accuracy explained 53% of intelligibility variance; mouthing explained an additional 11%.
Conclusions:
- Accuracy is the primary driver of SEE interpreter intelligibility.
- Lag time has a minimal effect, but optimal ranges exist for intelligibility.
- Further research should explore other factors like nonmanual markers and synchronization.

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Scientists typically make repeated measurements of a quantity to ensure the quality of their findings and to evaluate both the precision and the accuracy of their results. Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or the accepted value. Precise values agree with each other; accurate values agree with a true value. Highly accurate...

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Errors in taping arise from multiple factors that can significantly impact measurement accuracy in surveying. Misalignment of the tape, often due to human error, is one primary source. A skilled rear tapeman, using a telescope, can help correct alignment by guiding the head tapeman; however, human limitations still lead to small inaccuracies. These errors may include misplacement of pins or inaccurate tape readings due to common visual confusions, such as mistaking a six for a nine. Such...
