In the Face of Terrorism: Evidence that Belief in Literal Immortality Reduces Prejudice Under Terrorism Threat

Based on terror management theory, previous research has shown that terrorism threat increases prejudice against Muslims and is mediated by death‐related thoughts. Because this effect was found on a correlational level, it remains unclear whether terrorism threat increases prejudice against Muslims because of enhanced death‐related thoughts or the opposite: terrorism threat increases death‐related thoughts because of stronger prejudice against Muslims. To disentangle this shortcoming, we varied death‐related thoughts by systematically manipulating the belief in literal immortality. Using two studies, we found that participants exposed to terrorism pictures (vs. controls) had increased prejudice against both Muslims (Study 1) and immigrants (Study 2) when they were led to believe that literal immortality does not exist but not when they were led to believe that it does exist. Mediation analysis indicated that this effect was mediated by death‐related thoughts. This provides further evidence that terrorism threat increases prejudice because of death‐related thoughts.     

Lifelong Learning: A Pacification of ‘Know How’

A tendency of previous studies of lifelong learning to focus on learning and learning subjectivities may have led to an underestimation of potential effects in terms of a system of knowledge constitutive processes that operates powerfully to shape our societies. In this paper we explore lifelong learning and practices in the construction of knowledge at the point where a new relationship is being attempted between university courses and workplaces through programmes for learning. Drawing from Foucault and others we argue a strategic relation between discourses of lifelong learning and knowledge practices in such locations. Discourses of lifelong learning appear to support the reaching out of disciplinary practices into the workplace where theoretical knowledge is combined with knowledge derived from work experience, as a new form of knowledge that has use value. Discipline as a modality of power appears reconfigured and multiplied in new power-knowledge constellations which aim to subdue the desire and power of know how. Rather than lifelong learning as learning apparatus and strategy in the promotion of a will to learn as has been suggested elsewhere, we offer an alternative account. Here the promotion of a will to learn articulates with the will to knowledge in part through discourses of lifelong learning. Practices of knowledge constitution support the pacification of know how through its reconfiguration as knowledge that can be codified and mobilized for economic innovation.     

Priming of reach and grasp actions by handled objects

Pictures of handled objects such as a beer mug or frying pan are shown to prime speeded reach and grasp actions that are compatible with the object. To determine whether the evocation of motor affordances implied by this result is driven merely by the physical orientation of the object's handle as opposed to higher-level properties of the object, including its function, prime objects were presented either in an upright orientation or rotated 90° from upright. Rotated objects successfully primed hand actions that fit the object's new orientation (e.g., a frying pan rotated 90° so that its handle pointed downward primed a vertically oriented power grasp), but only when the required grasp was commensurate with the object's proper function. This constraint suggests that rotated objects evoke motor representations only when they afford the potential to be readily positioned for functional action.     

Self-concealers: Do they conceal what we always assumed they do?

The present investigation empirically examined the relation between self-concealment and three secret typologies reported in the literature. For this aim a general population sample of 221 participants completed an online questionnaire that included the Self-concealment Scale (Larson & Chastain, 1990). Respondents also wrote down their most important secret. It was found that SC is positively associated with keeping secrets that concern convictions of personal inadequacy, sorrows, and worries that relate to oneself. In addition, it is concluded that self-concealed information refers in particular to secrets regarding personal inadequacy, sorrow, and worry. Implications for secrecy research are discussed and suggestions for future research are made.     

Ease of processing constrains the activation flow in the conceptual-lexical system during speech planning

In 3 picture-word interference experiments, speakers named a target object in the presence of an unrelated not-to-be-named context object. Distractor words, which were phonologically related or unrelated to the context object's name, were used to determine whether the context object had become phonologically activated. All objects had high frequency names, and the ease of processing of these objects was manipulated by a visual degradation technique. In Experiment 1, both objects were nondegraded; in Experiment 2, both objects were degraded; and in Experiment 3, either the target object or the context object was degraded. Distractor words, which were phonologically related to the context objects, interfered with the naming response when both objects were nondegraded, indicating that the context objects had become phonologically coactivated. The effect vanished when both objects were degraded, when only the context object was degraded, and when only the target object was degraded. These data demonstrate that the amount of available processing resources constrains the forward cascading of activation in the conceptual-lexical system. Context objects are likely to become phonologically coactivated if they are easily retrieved and if prioritized target processing leaves sufficient resources.     

Is there semantic interference in delayed naming?

The semantic interference effect in the picture-word interference task is interpreted as an index of lexical competition in prominent speech production models. Janssen, Schirm, Mahon, and Caramazza (2008) challenged this interpretation on the basis of experiments with a novel version of this task, which introduced a task-switching component. Participants either named the picture or read the word, depending on the word's color. Janssen et al. reported semantic interference in picture naming, regardless of whether the word appeared simultaneously with the picture (immediate naming) or 1,000 ms after the picture (delayed naming). Because picture name retrieval is completed in less than 1,000 ms, the finding in delayed naming was taken as evidence against the lexical competition account. In 3 sets of experiments conducted in German and English, we tested for semantic effects in Janssen et al.'s task-switching version and in the standard picture-word interference task. Using identical materials, we obtained sizeable interference effects in the standard task (Experiments 2, 4, and 6) but no effects in the task-switching version (Experiments 1, 3, and 5). When the word reading trials of the task-switching version were replaced with no-go trials (Experiment 7), semantic interference reemerged in immediate naming but was still absent in delayed naming. The experiments question the reliability of Janssen et al.'s critical finding and suggest that theoretical inferences about the origin of semantic effects in the standard picture-word interference task based on results from the task-switching version used by Janssen et al. are difficult to draw.     

The paddle move commonly used in magic tricks as a means for analysing the perceptual limits of combined motion trajectories

Following Gustav Kuhn's inspiring technique of using magicians' acts as a source of insight into cognitive sciences, we used the 'paddle move' for testing the psychophysics of combined movement trajectories. The paddle move is a standard technique in magic consisting of a combined rotating and tilting movement. Careful control of the mutual speed parameters of the two movements makes it possible to inhibit the perception of the rotation, letting the 'magic' effect emerge--a sudden change of the tilted object. By using 3-D animated computer graphics we analysed the interaction of different angular speeds and the object shape/size parameters in evoking this motion disappearance effect. An angular speed of 540 degrees s(-1) (1.5 rev. s(-1)) sufficed to inhibit the perception of the rotary movement with the smallest object showing the strongest effect. 90.7% of the 172 participants were not able to perceive the rotary movement at an angular speed of 1125 degrees s(-1) (3.125 rev. s(-1)). Further analysis by multiple linear regression revealed major influences on the effectiveness of the magic trick of object height and object area, demonstrating the applicability of analysing key factors of magic tricks to reveal limits of the perceptual system.     

Anticipatory affect during action preparation: evidence from backward compatibility in dual-task performance

Upcoming responses in the second of two subsequently performed tasks can speed up compatible responses in the temporally preceding first task. Two experiments extend previous demonstration of such backward compatibility to affective features: responses to affective stimuli were faster in Task 1 when an affectively compatible response effect was anticipated for Task 2. This emotional backward-compatibility effect demonstrates that representations of the affective consequences of the Task 2 response were activated before the selection of a response in Task 1 was completed. This finding is problematic for the assumption of a serial stimulus-response translation stage. It also shows that the affective consequence of a response is anticipated during, and has an impact on stimulus-response translation, which implies that action planning considers codes representing and predicting the emotional consequences of actions. Implications for the control of emotional actions are discussed.     

Generalisation of the Clark and Wells cognitive model of social anxiety to children's athletic and sporting situations

Research has shown that social anxiety generalises to sporting and athletic situations. The present study explored the applicability of the Clark and Wells model of social anxiety – and its metacognitive extension – to sport anxiety. Participants were 290 students aged 11–13 years, who completed measures of sport anxiety, social anxiety, depression and cognitive variables implicated by the model. Hierarchical regression analysis indicated that performance attitudes, performance cognitions, anticipatory and post-event processing were predictive of sport anxiety, after controlling for social anxiety and depression. In addition, the association between performance attitudes and sport anxiety was stronger at higher levels of anticipatory and post-event processing. These results suggest that the Clark and Wells cognitive model – and its metacognitive extension – is applicable to children with sport anxiety.     

New account of empirical claims in structuralism

In this paper, a new account of empirical claims in structuralism is developed. Its novelty derives from the use that is made of the linguistic approach to scientific theories despite the presumed incompatibility of structuralism with that approach. It is shown how the linguistic approach can be applied to the framework of structuralism if the semantic foundations of that approach are refined to do justice to the doctrine of indirect interpretation of theoretical terms. This doctrine goes back to Carnap but has been advanced until the present day without a proper semantic explanation.
