Media coverage of the 2003 Iraq War frequently contained corrections and retractions of earlier information. For example, claims that Iraqi forces executed coalition prisoners of war after they surrendered were retracted the day after the claims were made. Similarly, tentative initial reports about the discovery of weapons of mass destruction were all later disconfirmed. We investigated the effects of these retractions and disconfirmations on people's memory for and beliefs about war-related events in two coalition countries (Australia and the United States) and one country that opposed the war (Germany). Participants were queried about (a) true events, (b) events initially presented as fact but subsequently retracted, and (c) fictional events. Participants in the United States did not show sensitivity to the correction of misinformation, whereas participants in Australia and Germany discounted corrected misinformation. Our results are consistent with previous findings in that the differences between samples reflect greater suspicion about the motives underlying the war among people in Australia and Germany than among people in the United States.  相似文献

Many languages without separate terms for green and blue are or were spoken in locations receiving above-average exposure to ultraviolet-B (UV-B) radiation. It has been proposed that this correlation is caused by premature lens aging. This conclusion was supported by an experiment in which younger observers used the term "blue" less often when they described simulated paint chips filtered through the equivalent of an older observer's lens-removing much short-wavelength light-than when they described the unfiltered versions of the same paint chips. Some stimuli that were called "blue" without simulated aging were called "green" when filtered. However, in the experiment reported here, we found that the proportion of "blue" color-name responses did not differ between younger subjects and older observers with known ocular media optical densities. Color naming for stimuli that were nominally green, blue-green, or blue was virtually identical for older and younger observers who viewed the same (unfiltered) stimuli. Our results are inconsistent with the lens-brunescence hypothesis.  相似文献

Functional equivalence and stimulus equivalence classes were established, reversed, and tested for stability with college students. Functional stimulus classes were established using a task in which students were trained to say nonsense words in the presence of arbitrarily assigned sets of symbols. Computer-controlled speech-recognition technology was used to record and analyze students' vocal responses for accuracy. After the establishment of stimulus classes was demonstrated with a transfer-of-function test, the effects of reversing selected baseline simple discriminations were assessed during an additional transfer-of-function test and a follow-up test that occurred several weeks later. With the same students, stimulus equivalence classes were established and demonstrated with computerized matching-to-sample procedures. The effects of reversing selected baseline conditional discriminations also were assessed during a postreversal equivalence test and a follow-up test. Both functional stimulus classes and stimulus equivalence were sensitive to contingency reversals, but the reversals with stimulus equivalence closses affected stimulus class organization whereas reversals with functional stimulus classes did not. Follow-up performances were largely consistent with the original baseline contingencies. The similarities and differences between stimulus equivalence and functional equivalence are related to the specific contingencies that select responding in the presence of the stimuli that form the classes.  相似文献

Reaction times (RTs) to randomly ordered stimuli are influenced in various ways by the sequence of preceding events. Depending on the response-stimulus interval and stimulus-response compatibility, cost-only or cost-benefit patterns can be observed. In order to localize these effects within the information-processing system, different sequential patterns were induced in overt performance. RTs and amplitude developments of the lateralized readiness potential (LRP) across several trials indicated the accumulation of residual traces as a possible mechanism underlying sequential effects. Analysis of LRP onsets indicated two possible loci of action of such traces. Whereas in motoric stages trace accumulation appeared to produce processing advantages only for continued event repetitions, without corresponding costs for discontinuations, cost-benefit patterns were consistently observed in premotoric stages.  相似文献

The core values of hospitality, respect, and innovation help to guide and initiate changes in the worship services of a rehabilitation hospital. The Antiphon of the day, special hymnals containing residents choices, and inclusion in the prayers of the day helped achieve these goals. Residents are constantly given choices with the Chaplain ready to keep the service moving smoothly. In these ways the core values are included in all services. Specific resources are listed, and the article is followed by a response from another chaplain with a somewhat different approach.  相似文献

After the Second World War up to the 1980s Harald Schultz-Hencke’s so-called German neopsychoanalysis was an important theoretical reference for psychoanalysts in the German Psychoanalytical Society (DPG). Simultaneously, however, references were increasingly being made to quintessential psychoanalytical sources which of course had an impact on the psychoanalytical training. The references in final papers of a DPG psychoanalytical institute from 1971–2008 were compared to the references in clinical papers of the International Journal of Psychoanalysis. It can be shown that the influence of German neopsychoanalysis in the final theses of the psychoanalytical institute in question has diminished since the 1990s and has become irrelevant in the twenty-first century.  相似文献

Two experiments used clinical validation to increase scrutiny of messages posted in public settings. The first experiment used a 2 (validation: no/yes) × 2 (persuasion: none/"it is important") factorial design to develop messages about newspaper recycling. The prompt (no validation/no persuasion) had little impact on newspaper recycling, but the other 3 signs all resulted in increased recycling while the signs were in place. After signs were removed, recycling remained significantly higher than baseline (marginally significant for validation/persuasion). At the end of the study, number of cognitions favoring recycling was significantly higher in the validation-only condition and was lower in the validation/persuasion condition. Experiment 2 tested whether signs would have more impact if they were sensitive to the social ecology of newspaper recycling; that is, readers' tendency to leave newspapers behind so others may read them. Messages based on a 2 (message: validation-only/validation plus persuasion) × 2 (ecology: no social ecology/social ecology) factorial design supported social ecology's importance. Furthermore, because of the increased sharing in the social ecology conditions, total numbers of newspapers used was significantly lower in those buildings. Validation only yielded sustained behavior change in both Experiments 1 and 2, supporting additional research on the question of whether validation can, by itself, lead to cognitive elaboration and self-persuasion.  相似文献

A study with multiple baseline design across situations and response-classes was used to evaluate the effects of a water mist procedure used for punishment of two classes of problem behaviour in a 50-year-old woman with severe mental retardation. Problem behaviour was reduced to less than 5% of baseline. After 19 months the problem behaviour was still reduced, and had stabilized at a level below 10% of baseline. Due to financial economies the local community authorities terminated the treatment, which resulted in a marked increase in the rate of problem behaviour.  相似文献

Although the intergenerational transmission of trauma has been well documented, the pathways by which trauma symptoms are passed between parents and children remain unclear. This study examined the mediating role of parenting styles in the transmission of maternal trauma to children. Participants were a sample of 105 mothers of toddlers (18–30 months old). Mothers who had experienced interpersonal trauma were more likely to have an authoritarian parenting style, including verbal hostility, physical coercion, and low nurturance. Verbal hostility especially predicted more prevalent and increasing toddler symptoms associated with affective, hyperactive, and oppositional defiant disorders. Thus, the verbal hostility component of authoritarian parenting could serve as a major intergenerational pathway between maternal trauma and early child symptoms.  相似文献

The question of whether words can be identified without spatial attention has been a topic of considerable interest over the last five and a half decades, but the literature has yielded mixed conclusions. The present experiments manipulated the proportion of valid trials (the proportion of trials in which a cue appeared in the same location as the upcoming target word) so as to encourage distributed (50% valid cues; Experiments 1 and 3) or focused (100% valid cues; Experiments 2 and 4) spatial attention in a priming-type paradigm. Participants read aloud a target word, and the impact of a simultaneously presented distractor word was assessed. Semantic and orthographic priming effects were present when conditions promoted distributed spatial attention but absent when conditions promoted focused spatial attention. In contrast, Experiment 5 yielded a distractor word effect in the 100% valid cue condition when subjects identified a colour (Stroop task). We take these results to suggest that (1) spatial attention is a necessary preliminary to visual word recognition and (2) examining the role of spatial attention in the context of the Stroop task may have few implications for basic processes in reading because colour processing makes fewer demands on spatial attention than does visual word recognition.  相似文献
