简要总结
This study is being conducted to learn more about how various personal and situational characteristics are related to the ability to provide verbal descriptions of photographs. Participants will perform a brief mental exercise, then see three photographs with instructions to describe each thoroughly. Participants will also complete several other surveys and measures. Collected data will give researchers a better understanding of how different variables relate to speech production.
详细描述
This study is being conducted to learn more about how various personal and situational characteristics are related to the the ability to provide verbal descriptions of photographs. Adult participants ages 18-30 and 65-80 will participate in videoconference calls during which they perform a brief mental exercise, then see three photographs with instructions to describe each thoroughly. Descriptions are to be 30 to 60 seconds in length and are audio recorded for later scoring. Participants will also complete several other surveys and measures, including some about anxiety, mindfulness, vocabulary, and demographics. Participation will take approximately 40 to 60 minutes. Collected data will be de-identified, and the aggregate data will give researchers a better understanding of how individuals' personality and cognitive traits and the mental exercise performed before the study relate to peoples' speech production performance.

结局指标
主要结局
Speech Rate
时间窗: During the 40 to 60 minute experimental session
Average number of words per second spoken
Repetitions
时间窗: During the 40 to 60 minute experimental session
Average number of repetitions as a percentage of words spoken
Speech Fillers Other
时间窗: During the 40 to 60 minute experimental session
Average number of speech fillers not in the middle of a phrase as a percentage of words spoken
Speech Fillers Mid-Phrase
时间窗: During the 40 to 60 minute experimental session
Average number of mid-phrase speech fillers as a percentage of words spoken
Repairs Plus False Starts
时间窗: During the 40 to 60 minute experimental session
Average number of repairs plus false starts as a percentage of words spoken. These two measures reflect the same underlying process so are summed together; indeed, one or the other term is sometimes used to indicate both measures.
