The debate over off-line simulation has largely focussed on the capacity to predict behavior, but the basic idea of off-line simulation can be cast in a much broader framework. The central claim of the off-line account of behavior prediction is that the practical reasoning mechanism is taken off-line and used for predicting behavior. However, there's no reason to suppose that the idea of off-line simulation can't be extended to mechanisms other than the practical reasoning system. In principle, any cognitive component can be taken off-line and used to perform some other function. On this view of off-line simulation, such accounts differ radically from traditional information-based accounts of cognitive capacities. And cognitive penetrability provides a wedge for empirically determining whether a capacity requires an information-based account or an off-line simulation account. Stich and Nichols (1992) argued that the simulation theory of behavior prediction was inadequate because behavior prediction seemed to be cognitively penetrable. We present empirical evidence that supports the claim that the behavior prediction is cognitively penetrable. As a result, the simulation account of behavior prediction still seems unpromising. However, off-line simulation might provide accounts of other cognitive capacities. Indeed, off- line simulation accounts have recently been offered for a strikingly diverse set of capacities including counterfactual reasoning, empathy and mental imagery. Goldman, for instance, maintains that counterfactual reasoning and empathy clearly demand off-line simulation accounts. We argue that there are alternative information-based explanations of these phenomena. Nonetheless, the off-line accounts of these phenomena are interesting and clearly worthy of further exploration

Human social intelligence comprises a wide range of complex cognitive and affective processes that appear to be selectively impaired in autistic spectrum disorders. The study of these neuro- developmental disorders and the study of canonical social intelligence have advanced rapidly over the last twenty years by investigating the two together. Specifically, studies of autism have provided important insights into the nature of ‘theory of mind’ abilities, their normal development and underlying neural systems. At the same time, the idea of impaired development of the neurocognitive mechanisms underlying ‘theory of mind’ has shed new light on the nature of autistic disorders. This general approach is not restricted to the study of impairments but extends to mapping areas of social intelligence that are spared in autism. Here we investigate basic moral judgment and find that it appears to be substantially intact in children with autism who are severely impaired in ‘theory of mind’. At the same time, we extend studies of moral reasoning in normal development by way of a new control task, the ‘cry baby’ task. Cry baby scenarios, in which the distress of the victim is ‘unreasonable’ or ‘unjustified,’ do not elicit moral condemnation from normally developing preschoolers or from children with autism. Judgments of moral transgressions in which the victim displays distress are therefore not likely the result of a simple automatic reaction to the distress and more likely involve moral reasoning. Mapping the cognitive co-morbidity patterns of disordered development should encompass both impairments and sparings because both will be needed to make sense of the neural and genetic levels.
