This research examines the ability of consumers to predict the appeal of complete visual patterns from small sample fragments. In a task designed to mimic the dilemma of choosing wallpaper from small swatches, study participants are shown fragments taken from a large pattern design and are asked to predict how attractive they would find the complete image. Drawing on prior research on affective forecasting, predictions are hypothesized to be driven by an anchoring‐and‐adjustment process that skews forecasts toward the attractiveness of fragments when judged in isolation. Results from 3 laboratory studies support this basic hypothesis: Respondents consistently overestimate the degree to which their initial reactions to fragments predict their subsequent evaluations of wholes. The size of this projection bias is, in turn, conditioned by such moderators as prior familiarity with product fragment, cognitive load, and visualization abilities—effects that are consistent with an anchoring‐and‐adjustment explanation for the data. 相似文献

Many depressed people, young men in particular, do not seek professional help. This social constructionist action research project aimed to construct a comprehensive self‐help website for students. Its goal was to give a multi‐layered (‘thick’) account of depression to website users offering empowering perspectives and strategies while challenging barriers to help‐seeking. Thirteen student interviewees, representing diverse demographics and depression experiences, attended semi‐structured interviews to elicit ‘coping’ narratives. Ten of them then formed an ongoing e‐mail focus group. An evaluative action research spiral was used to analyse and act upon public health guidelines, student interviews and student focus group commentary. Triangulation was provided via the specifications and ongoing feedback from the other project stakeholders. These were the funding charity steering group (including heads of university counselling services); the university providing programme/ethical approval; and the expert group offering clinical validation. The final site at www.studentdepression.org has nearly 100 pages of information and self‐help resources cross‐referenced with personal narratives. It provides a rich, complex account of how depression may be tackled and resisted. Both student and expert groups were impressed with final site quality and usefulness. Collaborative development with user‐group representatives is likely to have produced a far richer, more accessible and more comprehensive resource than counsellor authorship alone. 1 1Formerly at the Counselling Service, Royal Holloway University of London, UK.

Self‐control was studied in an iterated one‐player Prisoner's Dilemma game in which students' choices affected the payoff matrix on the next trial. The frequency of self‐control responses (choice of the smaller payoff now, but with the more generous payoff matrix more likely on the next trial) and defection responses (choice of the larger payoff now, but with the less generous payoff matrix more likely on the next trial) were measured. In Experiment 1, players achieved a criterion of five consecutive self‐control responses more quickly as a positive function of trial spacing, the presence between trials of a discriminative stimulus associated with the upcoming payoff matrix, and the probability that the self‐control or defection response would be reciprocated by the computer. Experiment 2 replicated the effect of trial spacing except when there was an interfering task during the interval, suggesting that trial spacing permits better appreciation of the contingencies.

Categorization is a process that spans all of development, beginning in earliest infancy yet changing as children's knowledge and cognitive skills develop. In this review article, we address three core issues regarding childhood categorization. First, we discuss the extent to which early categories are rooted in perceptual similarity versus knowledge‐enriched theories. We argue for a composite perspective in which categories are steeped in commonsense theories from a young age but also are informed by low‐level similarity and associative learning cues. Second, we examine the role of language in early categorization. We review evidence to suggest that language is a powerful means of expressing, communicating, shaping, and supporting category knowledge. Finally, we consider categories in context. We discuss sources of variability and flexibility in children's categories, as well as the ways in which children's categories are used within larger knowledge systems (e.g., to form analogies, make inferences, or construct theories). Categorization is a process that is intrinsically tied to nearly all aspects of cognition, and its study provides insight into cognitive development, broadly construed.

This series of studies focuses on the extent to which the personality of followers is related to their perception of transformational leadership. Followers from 3 different companies and students from a Dutch university were questioned on their personality characteristics and their perception of a described leader (students) or the perception of their actual leader (employees). Although the results differ for the different samples, we found a relationship between followers' personality and the perception of transformational leadership for all of the different samples. The different relationship that we found may hint to the impact of context on the relationship between personality and the perception of leadership. In the discussion, we explain our results in light of these different contexts. 相似文献

This study examined relationships between symptoms of anxiety, aggression, and depression, on the one hand, and threat perception distortions, on the other hand. A large sample of typically developing children aged 8–12 years (N=157) were interviewed with an instrument for assessing the main types of childhood psychopathology, and were then exposed to a series of ambiguous vignettes in order to measure threat perception. As all measures were obtained twice, some 8 weeks apart, it was also possible to study prospective relationships between threat perception distortions and psychopathological symptoms. Results showed that threat perception was associated with a broad range of psychopathological symptoms, although the connection with anxiety was the most robust. No support was found for the notion that threat perception scores were predictive for the persistence of psychopathological symptoms during the 8‐weeks period.
