Table 1
Norms of the 1189 photographs. Modal name agreement is the percentage of people that gave the most common name (calculated over the modal_NA, not modal_NA_all column in OSF Table C). H is a measure of entropy describing name agreement. DKO refers to the percentage of participant who indicated they did not recognize the object. DKN is the percentage of participant who indicated they did not know the name of the object. Object agreement is how well the photographs resembled the object shown (rated on a 5-point scale). Zipf scores for word frequency, word prevalence, and Age of Acquisition were added from different databases.
| VARIABLE | MEAN | SD | MIN | MAX |
|---|---|---|---|---|
| Modal name agreement (%) | 71 | 23 | 21 | 100 |
| H-value name | 1.2 | 0.9 | 0 | 3.7 |
| DKO (%) | 2 | 4 | 0 | 20 |
| DKN (%) | 6 | 10 | 0 | 72 |
| Object agreement | 4.2 | 0.5 | 2 | 5 |
| Frequency (Zipf) | 3.5 | 0.9 | 1.7 | 6.6 |
| Prevalence | 1.84 | 0.13 | 0.88 | 1.96 |
| Age of acquistion | 7 | 2 | 4 | 14 |

NA = Name Agreement; H = H-value; OA = Object Agreement; %DKO = percentage of trials in which participants did not recognize the object; %DKN = percentage of trials in which participants did not know the name of the object; Zipf = Zipf score for word frequency; WP = Word Prevalence (z-scores); AoA = Age of Acquisition.
