Negative transfer errors in sequential cognitive skills: strong-but-wrong sequence application.

Three experiments investigated the role of processing sequence knowledge in negative transfer within multistep cognitive skills. In Experiments 1 and 2, more training resulted in higher error rates when new processing sequences that resembled familiar ones were introduced in transfer. Transfer error responses were executed with the same speed as correct responses to familiar sequence trials, and the errors appeared to be undetected by the performers. Experiment 3 tested whether the effects of sequence learning were attributable to explicit or implicit knowledge of processing sequences. Evidence favored the implicit learning interpretation. Findings are discussed in relationship to earlier demonstrations of the einstellung effect and to current taxonomic theories of human error.

Preferences of old and young Navaho Indians for Western and indigenous health care providers: an exploratory study.

References for Western versus traditional health care providers were assessed in 27 older (M = 61.5 years) and 21 younger (M = 22.6 years) American Indians living on the Navaho reservation. Participants were read standardized vignettes depicting diagnosable physical and emotional illnesses, and they completed a series of forced-choice questions indicating their preference for traditional or Western health care providers for treating these conditions. Analysis of variance (ANOVA) was used to assess health care provider preference with age, interviewer, and illness type as independent variables. Medical doctors were preferred over all other health care providers for physical problems, and this was particularly true for the younger group. Although it was anticipated that the older participants would favor traditional healers and the younger participants would prefer Western options, there was no main effect for age. This lack of differentiation by age in provider preference was interpreted in terms of informal utilization patterns and the role of the family referral system inherent in this group of indigenous adults.

Perceptual and conceptual priming in a semantic reprocessing task.

Two experiments are reported that addressed the relative involvement and nature of perceptual and conceptual priming in a semantically complex task. Both experiments investigated facilitation from repeated semantic comparison trials in which subjects decided whether two words had the same meaning (e.g., moist damp). The first experiment compared the magnitude and persistence of perceptual and conceptual priming components. Perceptual priming effects were modest, and contrary to some previous evidence, they did not appear to be more persistent than nonperceptual priming effects. The second experiment investigated the memory processes involved when perceptual priming was eliminated through a modality change between prime and target trials. Evidence suggested that conceptual priming primarily involved memory for the meaning comparison processes rather than better access to existing memory for the stimulus words.
