Cognitive psychologists have not devoted much attention to semantic and emotional effects early in word recognition, assuming instead that such effects are primarily post-perceptual. Some evidence of such early effects does exist, but it relies exclusively on a less-than-ideal experimental task, the lexical decision task. In the current study, participants heard words over headphones and repeated them into a microphone as quickly as possible (single-word naming). The Danger and Usefulness of word referents were significantly related to naming times, independent of effects such as word length, familiarity, onset characteristics, stress, neighbourhood density, and concreteness. Results are discussed in terms of the adaptive benefit of making quick classifications along these dimensions, and against a backdrop of evidence from several widely divergent areas of research. 相似文献

The case records of 29 mentally disordered offenders who committed suicide in a state hospital were reviewed. Information was collected on demographic and clinical characteristics; time, method and location of the suicides; and the presence of suicide indicators. Comparisons were made between the characteristics of the suicide patients and those of the current hospital population. Major findings were: 80 percent of the suicides were committed by psychotic patients and 66 percent were by patients with diagnoses which included paranoia; 48 percent of the suicide patients had been charged with or convicted of murder or attempted murder; most suicides occurred in individual patient rooms; nearly 50 percent of the patients had a history of suicide attempts; and other common indicators of suicide risk were often masked by psychotic symptomatology. Several recommendations for identifying and managing potentially suicidal patients in this population are presented. 相似文献
