An Experimenter Predicts That Using a Warning Signal in a Different

question 15

Multiple Choice

An experimenter predicts that using a warning signal in a different sensory modality will result in faster reaction time than using a warning signal in the same sensory modality. In a simple reaction time experiment, participants must press a button as quickly as possible when a red light comes on. On half of the trials, a yellow light comes on 500 ms before the red light; on the remaining trials, a tone comes on 500 ms before the red light. The results show a significant difference in reaction time between the two conditions. Which of the following statements is accurate?

• A) A warning signal given in the same sensory modality is more effective than one in a different sensory modality.
• B) A warning signal given in a different sensory modality is more effective than one in the same sensory modality.
• C) There is no difference in the effectiveness of a warning signal based on its sensory modality.
• D) We cannot determine which warning signal was more effective based on the information given.
