Teaching reasoning.

Twentieth-century psychologists have been pessimistic about teaching reasoning, prevailing opinion suggesting that people may possess only domain-specific rules, rather than abstract rules; this would mean that training a rule in one domain would not produce generalization to other domains. Alternatively, it was thought that people might possess abstract rules (such as logical ones) but that these are induced developmentally through self-discovery methods and cannot be trained. Research suggests a much more optimistic view: even brief formal training in inferential rules may enhance their use for reasoning about everyday life events. Previous theorists may have been mistaken about trainability, in part because they misidentified the kind of rules that people use naturally.

Long-term effects of losing a spouse or child in a motor vehicle crash.

In this article we examine the long-term effects of the sudden, unexpected loss of a spouse or child. In the spouse study, interviews were conducted with 39 individuals who had lost a spouse in a motor vehicle crash 4 to 7 years ago and with 39 matched controls. In the parent study, interviews were conducted with 41 parents who had lost a child in a crash and with 41 matched controls. Control respondents were matched to bereaved respondents case-by-case on the basis of sex, age, income, education, and number and ages of children. Significant differences between bereaved spouses and controls were revealed on several indicators of general functioning, including depression and other psychiatric symptoms, social functioning, psychological well-being, reactivity to good events, and future worries and concerns. For the most part, these differences persisted when variables such as present family income and present marital status were statistically controlled. Comparisons between bereaved and control parents also revealed significant differences on some measures of general functioning (especially depression), but these were not as pervasive as the differences obtained in the spouse study. Responses to questions about current thoughts and feelings suggest that the deceased continued to occupy the thoughts and conversations of bereaved spouses and parents. Moreover, a large percentage of respondents (from 30% to 85%, depending on the question), continued to ruminate about the accident or what might have been done to prevent it, and they appeared to be unable to accept, resolve, or find any meaning in the loss. Taken together, the data provide little support for traditional notions of recovery from the sudden, unexpected loss of a spouse or child.
