Temporal distinctiveness and repetition benefits in task switching: Disentangling stimulus-related and response-related contributions

Despite the popularity of the Wason selection task in the psychology of reasoning, doubt remains as to whether card choices actually reflect a process of reasoning. One view is that while participants reason about the cards and their hidden sides—as indicated by protocol analysis—this reasoning merely confabulates explanations for cards that were preconsciously cued. This hypothesis has apparently been supported by studies that show that participants predominantly inspect cards which they end up selecting. In this paper, we reanalyse the data of one such study, which used eye-movement tracking to record card inspection times (Ball, Lucas, Miles, & Gale, 2003). We show that while cards favoured by matching bias are inspected for roughly equal lengths of times, their selection rates are strongly affected by their logical status. These findings strongly support a two-stage account in which attention is necessary but not sufficient for card selections. Hence, reasoning does indeed affect participants' choices on this task.     

Identification of shareholder ethics and responsibilities in online reverse auctions for construction projects

The increasing number of companies providing internet services and auction tools helped popularize the online reverse auction trend for purchasing commodities and services in the last decade. As a result, a number of owners, both public and private, accepted the online reverse auctions as the bidding technique for their construction projects. Owners, while trying to minimize their costs for construction projects, are also required to address their ethical responsibilities to the shareholders. In the case of online reverse auctions for construction projects, the ethical issues involved in the bidding technique directly reflects on the owner’s ethical and social responsibilities to their shareholders. The goal of this paper is to identify the shareholder ethics and responsibilities in online reverse auctions for construction projects by analyzing the ethical issues for the parties involved in the process. The identification of the ethical issues and responsibilities requires clear definition and understanding of professional ethics and the roles of the involved parties. In this paper, first, the concept of professional ethics and social responsibility is described in a general form. To illustrate the ethical issues and responsibilities, a sample case of bidding for a construction project using online reverse auction techniques is presented in which the shareholders were actively involved in questioning the ethical issues. The issues involved in the bidding process and their reflection on the shareholder responsibilities are described and analyzed for each stage of the process. A brief discussion of the overall process is also included to address the general ethical issues involved in online reverse auctions. An earlier version of this paper was presented at the “Ethics and Social Responsibility in Engineering and Technology” meeting, New Orleans, 2003.     

Expectancies for Sexually Abused Children: Evidence of Perceiver Bias

We investigated perceiver bias in relation to children labeled as sexually abused. Building on recent research indicating that adults perceive children with such a label as having more behavioral problems and lower achievement, we replicated and expanded upon an earlier study. We tested undergraduate students (N = 699), who judged a six-year old child's aggressive behavior in vignettes that varied on severity of the aggressive behavior, child gender, and family history (sexually abused, mother dying of cancer, normal). Perceiver bias was related to family history label for internalizing behavior problems and competence issues and child gender for internalizing behavior problems and externalizing behavior problems. Implications for educators and practitioners are discussed as well as routes for future research.     

好意原则的局限性

Radical interpretation is used by Davison in his linguistic theory not only as an interesting thought experiment but also a general pattern that is believed to be able to give an essential and general account of linguistic interpretation. If the principle of charity is absolutely necessary to radical interpretation, it becomes, in this sense, a general methodological principle. However, radical interpretation is a local pattern that is proper only for exploring certain interpretation in a specific case, and consequently the principle of charity is an applicable principle in the limited scope. It is neither the case that every linguistic interpretation is in nature radical nor that the principle of charity is the primary and fundamental principle for all linguistic interpretation as Davidson believes.      

Perceptual-attentional and motor-intentional bias in near and far space

Spatial bias demonstrated in tasks such as line-bisection may stem from perceptual-attentional (PA) "where" and motor-intentional (MI) "aiming" influences. We tested normal participants' line bisection performance in the presence of an asymmetric visual distracter with a video apparatus designed to dissociate PA from MI bias. An experimenter stood as a distractor to the left or right of a video monitor positioned in either near or far space, where participants viewed lines and a laser point they directed under (1) natural and (2) mirror-reversed conditions. Each trial started with the pointer positioned at either the top left or top right corner of the screen, and alternated thereafter. Data analysis indicated that participants made primarily PA leftward errors in near space, but not in far space. Furthermore, PA, but not MI, bias increased bilaterally in the direction of distraction. In contrast, MI, but not PA, bias was shifted bilaterally in the direction of startside. Results support the conclusion that a primarily PA left sided bias in near space is consistent with right hemisphere spatial attentional dominance. A bottom-up visual distractor specifically affected PA "where" spatial bias while top-down motor cuing influenced MI "aiming" bias.     

Exaggeration in memory: Systematic distortion of self-evaluative information under reduced accessibility

The tendency to exaggerate specific information about oneself can stem from reconstructive memory processes that are distinct from motivated self-enhancement or self-presentation. While exaggerations sometimes reflect these motives, they also result from attempts to reconstruct one’s past. Three studies examined test scores as they became less accessible in memory. Study 1 provided a real-world illustration, demonstrating reduced accessibility and increased exaggeration of SAT scores over time. Two experiments utilized test scores randomly assigned in a controlled laboratory setting. Increased exaggeration was observed following distraction (Study 2), and after a one-week delay (Study 3). Distortions in scores reported were consistent with beliefs about the self, rather than uniformly self-serving. Under reduced accessibility, exaggeration was predicted by beliefs about achievement (Study 1) and subjective perceptions of test performance (Study 2). Study 3 manipulated perceived performance. Positive performance feedback caused greater exaggeration under reduced accessibility, whereas negative feedback reduced the tendency to exaggerate.     

Losing sight of oneself in the above-average effect: When egocentrism, focalism, and group diffuseness collide

Four experiments examined the relative influence of three causal processes in the above-average effect (AAE) and related comparative biases: (a) egocentrism, (b) focalism, and (c) referent group diffuseness. By manipulating the inclusion or exclusion of the self from the referent group (Experiments 1-3) or target group (Experiment 4), the relative contributions of each influence were assessed. In direct comparisons, single peers were systematically judged more favorably relative to groups including the self, suggesting that egocentrism plays a lesser role than focalism or group diffuseness. Thus, in response to the question such as “How friendly is Nancy compared to the rest of us?” the answer tends to be “More friendly.”     

Perceptual biases in processing facial identity and emotion

Normal observers demonstrate a bias to process the left sides of faces during perceptual judgments about identity or emotion. This effect suggests a right cerebral hemisphere processing bias. To test the role of the right hemisphere and the involvement of configural processing underlying this effect, young and older control observers and patients with right hemisphere damage completed two chimeric faces tasks (emotion judgment and face identity matching) with both upright and inverted faces. For control observers, the emotion judgment task elicited a strong left-sided perceptual bias that was reduced in young controls and eliminated in older controls by face inversion. Right hemisphere damage reversed the bias, suggesting the right hemisphere was dominant for this task, but that the left hemisphere could be flexibly recruited when right hemisphere mechanisms are not available or dominant. In contrast, face identity judgments were associated most clearly with a vertical bias favouring the uppermost stimuli that was eliminated by face inversion and right hemisphere lesions. The results suggest these tasks involve different neurocognitive mechanisms. The role of the right hemisphere and ventral cortical stream involvement with configural processes in face processing is discussed.     

Threat interpretation bias as a vulnerability factor in childhood anxiety disorders

The present study examined threat interpretation biases in children 7-12 years of age with separation, social and generalised anxiety disorders (N=15), non-anxious offspring at risk due to parental anxiety (N=16) and non-anxious controls of non-anxious parents (N=14). Children provided interpretations of ambiguous situations to assess cognitive, emotional and behavioural responses. In comparison with non-anxious control children and at-risk children who did not differ from each other, anxious children reported stronger negative emotion and less ability to influence ambiguous situations. These results suggest that threat interpretation bias may be a cognitive factor associated with ongoing childhood anxiety but not a vulnerability factor associated with parental anxiety.
