Detecting changes, in performance, sales, markets, risks, social relations, or public opinions, constitutes an important adaptive function. In a sequential paradigm devised to investigate detection of change, every trial provides a sample of binary outcomes (e.g., correct vs. incorrect student responses). Participants have to decide whether the proportion of a focal feature (e.g., correct responses) in the population from which the sample is drawn has decreased, remained constant, or increased. Strong and persistent anomalies in change detection arise when changes in proportional quantities vary orthogonally to changes in absolute sample size. Proportional increases are readily detected and nonchanges are erroneously perceived as increases when absolute sample size increases. Conversely, decreasing sample size facilitates the correct detection of proportional decreases and the erroneous perception of nonchanges as decreases. These anomalies are however confined to experienced samples of elementary raw events from which proportions have to be inferred inductively. They disappear when sample proportions are described as percentages in a normalized probability format. To explain these challenging findings, it is essential to understand the inductive-learning constraints imposed on decisions from experience. 相似文献

Objective: Individuals’ illness perceptions predict health behaviours and influence functional outcomes. This study examined associations between a novel assessment of illness perceptions, in the form of adult’s brain drawings after traumatic brain injury (TBI) and questionnaire measures of illness perceptions, quality of life and post-concussive symptoms.Design: Population-based, prospective longitudinal study examining 245 adults with predominantly mild TBI with high risk of complications.Main outcome measures: Participants were asked to draw pictures of what they thought their brain looked like before injury and at baseline and one month post-injury. Drawing characteristics (height, width and percentage damage at one month) were examined in relation to each outcome of interest at six months.Results: Greater damage at one month was associated with more negative illness perceptions (rs = .23), poorer mental health (rs = ?.21), and more total post-concussive symptoms (rs = .27 to r = .35) at six months. The extent of damage depicted reduced over time (p < .001). No associations were found between the amount of damage drawn and injury severity, nor the height or width of drawings and injury severity or illness perceptions.Conclusion: Drawings post-TBI offer a simple, cost- and time-effective way to begin discussions and improve understanding of peoples’ illness perceptions. 相似文献

While research indicates that mindfulness can benefit individual well-being, less is known about its potential impact in the interpersonal domain. In the current research, we examined whether a central element of mindfulness—decentering—decreases hostile attributions in ambiguous social situations. We hypothesized that decentering from experiences—observing and considering them as mental events that arise and disappear—hampers the development of hostile attributions. A series of three laboratory studies, two of which were high-powered and pre-registered, demonstrated that decentering decreases hostile attribution in response to ambiguous social scenarios as compared to immersion instructions, and as compared to baseline. Additionally, the results suggest that decentering may be particularly beneficial in reducing hostile attribution bias among participants high in trait rumination. The current findings provide initial insights into the effect of decentering on the development of hostile attribution bias, and the association between mindfulness and interpersonal responses more generally. 相似文献

The frequently cited finding that mood-congruent information can be better recalled than mood-incongruent information is tested using categorically organized stimulus material which imposes a systematic structure on the recall process. A target person was described with respect to six categories of social behaviour, with predominantly desirable behaviours in some categories and predominantly undesirable behaviours in others. Participants were induced either an elated mood state or a neutral state using Velten's procedure. Instructions (impression formation versus memory) were also manipulated. Although the mood manipulation apparently worked and did influence the impression judgments of the target person, it did not selectively facilitate the recall of mood-congruent material, neither at the level of specific items nor at the categorical level. However, when only deviating behaviours are considered which do not fit the structural constraints, mood-congruent information is indeed better recalled. To interpret these results, it is argued that the manifestation of mood effects depends on the restrictions of different tasks or response modes. Three other findings were obtained: Superior recall of redundant, structurally consistent information compared with deviating information; an advantage of positive over negative information which is confined to the impression formation condition; and, surprisingly, an incongruency effect for the encoding mood which may reflect the deeper processing of incongruent material. 相似文献

Preadolescent attitudes toward the elderly were examined through analysis of race, gender, and contact variables. Subjects were randomly selected preadolescents (mean = 12.8 years), a total of 157 students (91 boys and 66 girls), comprising three ethnic groups (49% white, 30% Mexican-American, 21% black). The investigator instructed each student to complete the Tuckman-Lorge Old People Scale, and a self-report contact questionnaire, thereby establishing three contact groups (high, medium, low). Data were analyzed via an ANOVA. The results revealed that only one of the variables studied, race, was significantly related to attitudes toward the elderly. The white preadolescents possessed the most positive attitudes toward the elderly. The greatest differences were between the white and black female preadolescents. These results suggest that preadolescent attitudes toward the elderly are culturally related. It can be concluded that as a variable, race should receive more attention in future attitudinal studies of the preadolescent. 相似文献

Starting from a concept of reasonableness as well-consideredness, it is discussed in what way science could serve as a model for reasonable argumentation. It turns out that in order to be reasonable two requirements have to be fulfilled. The argumentation should comply with rules which are both problem-valid and intersubjectively valid. Geometrical and anthropological perspectives don't meet these criteria, but a critical perspective does. It is explained that a pragma-dialectical approach to argumentation which agrees with this critical perspective is indeed problem-valid and that strong pragmatic and utilitarian arguments can be given for its intersubjective validity. Thus, conventional validity is promoted for a code of conduct for discussants who want to resolve their disputes reasonably by way of a critical discussion. 相似文献

In the course of a prospective longitudinal study, we examined age of onset of behavior problems in a group of boys and girls identified with attention deficit disorder (ADD) at age 11. Onset occurred during the preschool years, by the first year of schooling, or by the end of the second year of school. Onset was strongly related to informant source at age 11, pattern of comorbidity of disorder at age 11, and developmental language, perceptual motor, and IQ measures. Onset by the first year of schooling was particularly related to poor reading skills. By age 15, nearly three-quarters of those with onset of problems before age 6 had one or more DSM-III disorders. 相似文献

This study examined whether male and female supervisors differed in their delivery of performance feedback to subordinates. Male and female subjects supervised 2 confederate subordinates whose performance was stable and either above or below average. Supervisors regularly checked each subordinate's performance and could deliver one of several feedback messages. A MANOVA was performed on frequency of specific negative, general negative, specific positive, general positive, and neutral feedback messages, followed by step down analyses to isolate which dependent variables contributed uniquely. Male and female supervisors were distinguished by their use of specific negative feedback. Males were more likely to provide such messages to poorly performing subordinates, a result consistent with suggestions that males are characterized by a more directive leadership style. 相似文献
