The effects of existential threat on reading comprehension of worldview affirming and disconfirming information

Terror management theory posits that cultural worldviews buffer people from thoughts and concerns about death. In support of this claim, numerous studies have shown that mortality salience (MS) increases an individual's motivation to uphold and defend important cultural worldviews. We hypothesized that the motivation to defend cultural worldviews following MS would also enhance people's ability to comprehend worldview affirming (vs. disconfirming) information. Three studies investigated this possibility. Study 1 showed that MS (vs. control) increased reading comprehension of a pro‐evolution essay among participants with a strongly evolutionist worldview, but decreased reading comprehension among participants with a strongly creationist worldview. With the use of a pro‐creation essay, Study 2 conceptually replicated these effects and demonstrated that the interactive effect of worldview and death anxiety on reading comprehension was mediated by defensive motivation. Study 3 replicated the results of Studies 1 and 2 among participants with a strongly evolutionist worldview, but only when the information in the essay was perceived as veridical. Discussion focused on the specific process through which MS affects reading comprehension of worldview relevant ideas. Copyright © 2012 John Wiley & Sons, Ltd.     

Direct lexical control of eye movements in reading: evidence from a survival analysis of fixation durations

Participants' eye movements were monitored in an experiment that manipulated the frequency of target words (high vs. low) as well as their availability for parafoveal processing during fixations on the pre-target word (valid vs. invalid preview). The influence of the word-frequency by preview validity manipulation on the distributions of first fixation duration was examined by using ex-Gaussian fitting as well as a novel survival analysis technique which provided precise estimates of the timing of the first discernible influence of word frequency on first fixation duration. Using this technique, we found a significant influence of word frequency on fixation duration in normal reading (valid preview) as early as 145ms from the start of fixation. We also demonstrated an equally rapid non-lexical influence on first fixation duration as a function of initial landing position (location) on target words. The time-course of frequency effects, but not location effects was strongly influenced by preview validity, demonstrating the crucial role of parafoveal processing in enabling direct lexical control of reading fixation times. Implications for models of eye-movement control are discussed.     

Spatial judgments in the horizontal and vertical planes from different vantage points

Todorovi? (2008 Perception 37 106-125) reported that there are systematic errors in the perception of 3-D space when viewing 2-D linear perspective drawings depending on the observer's vantage point. Because these findings were restricted to the horizontal plane, the current study was designed to determine the nature of these errors in the vertical plane. Participants viewed an image containing multiple colonnades aligned on parallel converging lines receding to a vanishing point. They were asked to judge where, in the physical room, the next column should be placed. The results support Todorovi? in that systematic deviations in the spatial judgments depended on vantage point for both the horizontal and vertical planes. However, there are also marked differences between the two planes. While judgments in both planes failed to compensate adequately for the vantage-point shift, the vertical plane induced greater distortions of the stimulus image itself within each vantage point.     

Coarse-to-fine eye movement behavior during visual search

It has previously been argued that, during visual search, eye movement behavior is indicative of an underlying scanning “strategy” that starts on a global, or “coarse,” scale but then progressively focuses to a more local, or “fine,” scale. This conclusion is motivated by the finding that, as a trial progresses, fixation durations tend to increase and saccade amplitudes tend to decrease. In the present study, we replicate these effects but offer an alternative explanation for them—that they emerge from a few stochastic factors that control eye movement behavior. We report the results of a simulation supporting this hypothesis and discuss implications for future models of visual search.     

Heterogeneity of treatment changes after psychodynamic therapy within a one year follow‐up: A replication study

Naturalistic psychotherapy effect studies commonly report effect sizes for the total sample. However, a previous study of SCL‐90 Global Severity Index (GSI) improvement in a large outpatient sample used a cluster analytic strategy and reported clinical relevant outcome trajectories that could be grouped into early within‐treatment improvement, late improvement in the follow‐up period, and deteriorating patients with slight improvement that was lost at follow‐up. We explore GSI outcome trajectories and clinical significant change in a sample of 320 patients at a public psychiatric outpatient psychodynamic group therapy unit, the majority with anxiety, personality, and mood disorders. The study revealed large discharge and follow‐up effect sizes but more than one third of the patients were without measurable improvement. The major clusters described above were confirmed, and revealed unique clinical and socio‐demographic characteristics. Late improvers, as compared with early improvers, were characterized by anxiety symptoms and lack of network support after controlling for GSI at admission. Similarly, deteriorating patients had longer duration of illness and less favourable social characteristics compared with the other two groups. Early improving patients were less likely to have participated in short‐term groups, and only one third participated in additional treatment compared with more than 69% of the other patients. Severe and socially affected psychiatric patients, and patients with anxiety and agoraphobic symptoms may be less optimally treated in short‐term time limited psychodynamic groups. There is an obvious need for diversity of treatment offers, better integration of psycho‐social treatment components, and long‐term open ended treatment.     

Trust and the value of overconfidence: a Bayesian perspective on social network communication

The paper presents and defends a Bayesian theory of trust in social networks. In the first part of the paper, we provide justifications for the basic assumptions behind the model, and we give reasons for thinking that the model has plausible consequences for certain kinds of communication. In the second part of the paper we investigate the phenomenon of overconfidence. Many psychological studies have found that people think they are more reliable than they actually are. Using a simulation environment that has been developed in order to make our model computationally tractable we show that in our model inquirers are indeed sometimes better off from an epistemic perspective overestimating the reliability of their own inquiries. We also show, by contrast, that people are rarely better off overestimating the reliability of others. On the basis of these observations we formulate a novel hypothesis about the value of overconfidence.     

The Probability of Guilt in Criminal Cases: Are People Aware of Being ‘Beyond Reasonable Doubt’?

Data from a series of studies presenting video recorded witness statements to laypersons and legal professionals were examined to trace the relationship between judged probability of guilt and the willingness to vote guilty or not guilty in hypothetical trials, in the absence of specific jury instructions. The results show that a majority of jury‐eligible young and elderly participants, and police officers, were willing to convict a defendant when the judged probability of guilt exceeded .6. This is considerably below the legally accepted standard of ‘beyond reasonable doubt’, which usually is equated with a very high, around .9 perceived certainty. When jury deliberations were allowed, the threshold for conviction rose, approaching the standard evinced by trial judges under the same conditions. The results suggest that people prefer to vote for guilt according to a balance of probabilities principle, considering only the individual case, and disregarding the implied frequencies of false convictions.

Building an Environmental Ethics from the Confucian Concepts of Zhengming and Datong

From the ‘DuPont factory’ case in China, one can see that contemporary ecology is faced with two underlying problems: A lack of responsibility toward the environment beyond being economically profitable, and a lack of care for what is outside of one’s immediate environment. For the purpose of confronting these two problems, I suggest two Confucian concepts: 1. zhengming 正名 (Rectification of names) and 2. datong 大同 (Great Harmony). These two concepts can be used to develop an environmental ethics and thus play a crucial role in solving the two above-mentioned problems. Zhengming is originally a political concept that was put forward by Confucius. According to this concept, everyone should fulfill their duty to the utmost in accordance with their individual roles. Datong is Confucius’ political ideal and emphasizes gong 公 (public) as a spirit for caring for tian xia 天下 (all under Heaven). A Confucian-style harmonious society is achieved by ‘letting every being manifest its mandate to the full’ (ge jin xing fen 各盡性分). When we turn toward the natural environment instead of political affairs, these concepts of zhengming and datong can become a proactive view of environmental ethics. From this view, zhengming emphasizes that ‘humans fulfill their responsibility of being humans’ (ren ren 人人). This means that humans should take responsibility toward the natural world, and one might say that ren ren implies an impetus for protecting the environment. Similarly, datong emphasizes caring for tian xia, by not limiting oneself to certain races, species, national boundaries, or geographical regions. Because of this, I believe that zhengming and datong can certainly resolve the above-mentioned problems: A lack of a sense of responsibility toward the environment, and a lack of a sense of care for what is outside of the confines of one’s immediate environment.     

Character: The Prospects for a Personality‐Based Perspective on Morality

In the early parts of the 20th century, character made up a major part of psychology, specifically of personality psychology. However, an influential observational study of children's moral behavior, conducted by Hartshorne, May, and colleagues in the 1920s, suggested that consistency in morality‐related behavior was lower than many people expected. Some psychologists interpreted such results to mean that there was no consistency in moral behavior and thus that there were no stable, meaningful individual differences in moral behavior – character did not exist. Recent years have witnessed a reinvigoration of character, ethics, and morality as objects of psychological study. Our purpose in this paper is to contribute to this reinvigoration by reviewing the use of the concept of “character” within psychology, considering whether the evidence supports the notion of moral character as a psychological construct, and suggesting new prospects for research on moral character.
