Brief summary
This study is being conducted to learn more about how various personal and situational characteristics are related to the ability to produce names of pictured people. Participants will perform a brief mental exercise, then see 83 celebrity photographs to produce the names of. Participants will also complete other surveys and measures. Collected data will give researchers a better understanding of how different variables relate to proper name production.
Detailed description
This study is being conducted to learn more about how various personal and situational characteristics are related to the ability to produce names of pictured people. Adult participants ages 18-35 and 60-80 will participant in videoconference calls during which they will perform a brief mental exercise, then see 83 celebrity photographs with instructions to name each pictured person. The naming task will be video recorded for later scoring. Participants will also complete other surveys and measures, including some about demographics and other personal characteristics. Participation will take approximately 60-75 minutes. Collected will be de-identified and the aggregate data will give researchers a better understanding about how individual's personality and cognitive traits and the mental exercise performed before the study relate to people's proper name production.

SINGLE (Subject)
Masking description
Participants do not know which condition they are in, nor that there is another condition. They only know what mental exercise they will do in their assigned condition.
Intervention model description
Participants are randomly assigned to one of two mental exercises before performing a proper name production task and completing other measures.

Outcome results
Primary
Percent of Familiar Faces With TOT Responses
Percent of trials with name retrieval failures were measured on a task created for this purpose. Specifically, participants tried to provide names that fit photographs, indicating when a name got stuck on the tip of their tongue by saying TOT.
Time frame: During the 60-75 minute experimental session
Population: Some participants completed the experiment but their data were not included due to having distractions present during testing (e.g., another individual interrupting the participant), experiencing a terrible internet connection during testing, being uncomfortable with turning on their video during testing, and not meeting the age inclusion criteria after initially claiming that they did.
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| Mental Exercise: Intervention | Percent of Familiar Faces With TOT Responses | Young Adults | 16 Percent of familiar faces with TOTs | Standard Deviation 14 |
| Mental Exercise: Intervention | Percent of Familiar Faces With TOT Responses | Older Adults | 18 Percent of familiar faces with TOTs | Standard Deviation 14 |
| Mental Exercise: Control | Percent of Familiar Faces With TOT Responses | Young Adults | 15 Percent of familiar faces with TOTs | Standard Deviation 9 |
| Mental Exercise: Control | Percent of Familiar Faces With TOT Responses | Older Adults | 15 Percent of familiar faces with TOTs | Standard Deviation 12 |
