We take a fresh look at emotion recognition in autistic children, by testing their recognition of three different emotions (happy, sad, and surprise). The interest in selecting these is that whereas the first two are typical “simple” emotions (caused by situations), the third is typically a “cognitive” emotion (caused by beliefs). Because subjects with autism have clear difficulties in understanding beliefs, we predicted they would show more difficulty in recognising surprise. In contrast, as they have no difficulty in understanding situations (...) as causes of emotion, we predicted they would not show deficits in recognising happy and sad. These predictions were borne out, in a comparison with a group of normal children and in a group of subjects with mental handicap. This result shows the importance of fine-grain analysis in emotion-recognition tasks, and is discussed in relation to affective and theory of mind models of autism. (shrink)

An individual has a theory of mind if he imputes mental states to himself and others. A system of inferences of this kind is properly viewed as a theory because such states are not directly observable, and the system can be used to make predictions about the behavior of others. As to the mental states the chimpanzee may infer, consider those inferred by our own species, for example, purpose or intention, as well as knowledge, belief, thinking, doubt, guessing, pretending, liking, (...) and so forth. To determine whether or not the chimpanzee infers states of this kind, we showed an adult chimpanzee a series of videotaped scenes of a human actor struggling with a variety of problems. Some problems were simple, involving inaccessible food as in the original Kohler problems; others were more complex, involving an actor unable to extricate himself from a locked cage, shivering because of a malfunctioning heater, or unable to play a phonograph because it was unplugged. With each videotape the chimpanzee was given several photographs, one a solution to the problem, such as a stick for the inaccessible bananas, a key for the locked up actor, a lit wick for the malfunctioning heater. The chimpanzee's consistent choice of the correct photographs can be understood by assuming that the animal recognized the videotape as representing a problem, understood the actor's purpose, and chose alternatives compatible with that purpose.

An examination of the controversial "theory of mind" hypothesis, which states that children with autism are unable to comprehend other people's mental states. The theory relates to the most fundamental questions of normal development as well as to autism i.
