False belief vs. photo | |||
Saxe and Kanwisher, 2003 | fMRI n = 21 | Read a short vignette involving a person holding a false belief. Answer a question about her belief. e.g., John told Emily that he had a Porsche. Actually, his car is a Ford. Emily doesn’t know anything about cars so she believed John. When Emily sees John’s car, she thinks it is a …? (Porsche or Ford). | Read a false-photograph vignette. Answer a question concerning the outdated content in the photo. e.g., A photograph was taken of an apple hanging on a tree branch. The film took half an hour to develop. In the meantime, a strong wind blew the apple to the ground. The developed photograph shows the apple on the …? (tree or ground). |
Trait judgments | |||
Mitchell et al., 2002 | fMRI n = 34 | Read an adjective. Indicate whether it can be true for a hypothetical person. e.g., “nervous” … can it be true for “David?”? | Read an adjective. Indicate whether it can be true for an object. e.g., “sundried” … can it be true for “grape”? |
Strategic games | |||
Kircher et al., 2009 | fMRI n = 14 | Play the prisoner’s dilemma game (iterated version). You play with a human player for game points. Both players choose a cooperative or defective strategy on each trial. If both players choose defective, they gain almost no game points at all. If both choose cooperative, both gain some game points. If players choose differently, the defective player gains more points. | Play the prisoner’s dilemma game (iterated version). You play with a computer. |
Social animations | |||
Castelli et al., 2000 | PET n = 6 | Watch a video animation of two interacting triangles (e.g., mother and child are playing). Explain verbally what was happening (after fMRI). | Watch video animation of two randomly moving triangles. Explain verbally what was happening (after fMRI). |
Mind in the eyes | |||
Baron-Cohen et al., 1999 | fMRI n = 12 | View photographs of eyes. Indicate which of two words (e.g., concerned vs. unconcerned) describes the mental state of that person. | View photographs of eyes. Indicate if the person is male or female. |
Rational actions | |||
Brunet et al., 2000 | fMRI n = 8 | View a cartoon story and predict what will happen based on intentions of a character (no false belief). Choose a logical story ending from several options shown in pictures. e.g., A prisoner is in his cell. First, he breaks the bars of his prison window. Then he walks to his bed. Participants must indicate what will happen next … the prisoner ties a rope from the sheets on his bed/the prisoner shouts out loud. | View a cartoon story and predict what will happen based on physical causality. Choose a logical story ending from several options shown in pictures. e.g., A person is standing in front of a slide. A large ball is coming down this slide, heading toward the person standing there. Participants must indicate what will happen next … the ball is knocking over the person/the ball is resting on the ground and the person is standing next to it. |
