FIGURE 4.

A child-friendly guessing game found significant familiarity bias in children. (A) Participants were asked to guess the final word on a random page of a book. Physical copies of a familiar and unfamiliar book were shown, along with a page number and four possible final words for that page. Participants first indicated if they wanted to guess for the familiar book or the unfamiliar book, then indicated their guess from the four possible final words. Correct guesses (e.g., STUFF for the familiar book and COINS for the unfamiliar book) were rewarded with five additional tokens. (B) Percentage of participants that chose to guess for the familiar book. Dotted line indicates chance performance. *indicates significance at p < 0.05; +indicates p = 0.11.
