Research on children’s ability to attribute false mental states to others has focused exclusively on false beliefs. We developed a novel paradigm that focuses instead on another type of false mental state: false perceptions. From approximately 4 years of age, children begin to recognize that their perception of an illusory object can be at odds with its true properties. Our question was whether they also recognize that another individual viewing the object will similarly experience a false perception. We tested 33 preschool children with a task in which distorting lenses caused a small object to appear large and a large object to appear small. To succeed, children needed to recognize that a naive agent would falsely perceive the relative size of the objects and to correctly anticipate the agent’s actions on that basis. Children performed significantly better than chance in our false perception test, and there was a developmental progression in performance from 4 to 5 years of age similar to that seen in standard false belief tests. Our findings demonstrate that preschool children are capable of understanding that other individuals will be perceptually misled by illusory objects and that these false perceptions will influence their actions in predictable ways.

There is a persistent methodological problem in primate mindreading research, dubbed the 'logical problem,' over how to determine experimentally whether chimpanzees are mindreaders or just clever behavior-readers of a certain sort. The problem has persisted long enough that some researchers have concluded that it is intractable. The logical problem, I argue, is tractable but only with experimental protocols that are fundamentally different from those that have been currently used or suggested. In the first section, I describe what the logical problem is and how it can, in principle, be solved. In the second section, I illustrate how a well-known experimental protocol by Hare et al. fails to solve the logical problem. In the third section, I do the same for a protocol by Heyes . .) In the fourth section, I describe a novel experimental protocol for visual perspective-taking and argue that it succeeds to discriminate between the relevant mindreading and behavior-reading hypotheses. In addition, this new experimental protocol employs procedures that are realistic enough to suppose that chimpanzees might very well succeed in passing them

Metaphors of the mind abound. The mind has been metaphorically described as an aviary, a telephone switchboard, a ghost in a machine, and a computer - to name but a few. Bernard Baars, in his In the theater of consciousness, adds to this venerable list, arguing that the mind can be instructively thought of as a working theater. Baars argues for the aptness of his theater metaphor by showing how it can be used to tell "a unified story" of all the currently available scientific data on consciousness. This paper argues that Baars' theater metaphor is not entirely apt, that once it is unpacked, it suggests a certain relation between consciousness and attention that does not appear to be supported by the currently available data.
