Egocentric and geocentric frames of reference in memory of large-scale space

This experiment investigated the frames of reference used in memory to represent the spatial structure of a large-scale outdoor environment. Participants learned the locations of eight objects in an unfamiliar city park by walking through the park on one of two prescribed paths that encircled a large rectangular building. The aligned path was oriented with the building; the misaligned path was rotated by 45°. Later, participants pointed to target objects from imagined vantage points using their memories. Pointing accuracy was higher in the aligned than in the misaligned path group, and the patterns of results differed: In the aligned condition, accuracy was higher for imagined headings parallel to legs of the path and for an imagined heading oriented toward a nearby lake, a salient landmark. In the misaligned condition, pointing accuracy was highest for the imagined heading oriented toward the lake, and decreased monotonically with angular distance. These results indicated that locations of objects were mentally represented in terms of frames of reference defined by the environment but selected on the basis of egocentric experience.     

The word of others

Tyler Burge has argued that one has an a priori prima facie entitlement to believe in the truth of what one takes to have been presented as true by an interlocutor. This thesis, however, is problematic, since the alleged a priori prima facie entitlement to believe in the truth of our seeming understanding of things presented as true to us, rests on the possibility of determining assertoric force on a purely intellectual basis. This thesis is not plausible and Burge's analogy from memory does not support it. Two routes for defending Burge's thesis of the a priori prima facie entitlement to believe in the truth of what has been asserted can be identified: the Transcendental Route and the Intrinsic Rationality Route. David Lewis' account of linguistic convention would serve as a transcendental argument for the a priori prima facie entitlement to believe in the truth of what has been asserted, but flaws in Lewis' theory leave us deprived of any good transcendental argument for such an entitlement. The Intrinsic Rationality Route is in better standing, but we have yet to see an argument for why we should resort to that measure.     

Video game experience and its influence on visual attention parameters: An investigation using the framework of the Theory of Visual Attention (TVA)

Experts with video game experience, in contrast to non-experienced persons, are superior in multiple domains of visual attention. However, it is an open question which basic aspects of attention underlie this superiority. We approached this question using the framework of Theory of Visual Attention (TVA) with tools that allowed us to assess various parameters that are related to different visual attention aspects (e.g., perception threshold, processing speed, visual short-term memory storage capacity, top-down control, spatial distribution of attention) and that are measurable on the same experimental basis. In Experiment 1, we found advantages of video game experts in perception threshold and visual processing speed; the latter being restricted to the lower positions of the used computer display. The observed advantages were not significantly moderated by general person-related characteristics such as personality traits, sensation seeking, intelligence, social anxiety, or health status. Experiment 2 tested a potential causal link between the expert advantages and video game practice with an intervention protocol. It found no effects of action video gaming on perception threshold, visual short-term memory storage capacity, iconic memory storage, top-down control, and spatial distribution of attention after 15 days of training. However, observations of a selected improvement of processing speed at the lower positions of the computer screen after video game training and of retest effects are suggestive for limited possibilities to improve basic aspects of visual attention (TVA) with practice.     

The eyes grasp,the hands see: Metric category knowledge transfers between vision and touch

Categorization of seen objects is often determined by the shapes of objects. However, shape is not exclusive to the visual modality: The haptic system also is expert at identifying shapes. Hence, an important question for understanding shape processing is whether humans store separate modality-dependent shape representations, or whether information is integrated into one multisensory representation. To answer this question, we created a metric space of computer-generated novel objects varying in shape. These objects were then printed using a 3-D printer, to generate tangible stimuli. In a categorization experiment, participants first explored the objects visually and haptically. We found that both modalities led to highly similar categorization behavior. Next, participants were trained either visually or haptically on shape categories within the metric space. As expected, visual training increased visual performance, and haptic training increased haptic performance. Importantly, however, we found that visual training also improved haptic performance, and vice versa. Two additional experiments showed that the location of the categorical boundary in the metric space also transferred across modalities, as did heightened discriminability of objects adjacent to the boundary. This observed transfer of metric category knowledge across modalities indicates that visual and haptic forms of shape information are integrated into a shared multisensory representation.     

Perfectionism and Life Aspirations in Intrinsically and Extrinsically Religious Individuals

Religiosity is related to positive health and life satisfaction but the pathways through which this occurs have not been clearly delineated. The purpose of this study was to examine potential mediators of the relationships between intrinsic and extrinsic religiosity and negative affect and life satisfaction. Perfectionism and life aspirations are two possible pathways through which religious orientation is related to outcome. It was hypothesized that adaptive perfectionism and intrinsic life aspirations would act as mediators between intrinsic religiosity and negative affect and life satisfaction, and that maladaptive perfectionism and extrinsic life aspirations would act as mediators between the extrinsic religiosity and negative affect and life satisfaction. Two consecutive samples of religious college students (N = 540 and N = 485) completed measures of the Age Universal Religious Orientation Index, the Frost Multi-Dimensional Perfectionism Scale, the Aspiration Index, the Beck Depression Inventory-II, the Spielberger State-Trait Anxiety Inventory, and the Satisfaction with Life Scale. Intrinsic religiosity had a direct negative relationship with negative affect and positive relationship with life satisfaction. Contrary to the hypotheses, intrinsic religiosity had its strongest indirect effect via maladaptive perfectionism such that increased intrinsic religiosity was related to decreased maladaptive perfectionism which in turn lead to better negative affect and life satisfaction. Extrinsic religiosity was related to increased maladaptive perfectionism and thereby indirectly contributed to worse negative affect and life satisfaction. Interestingly, when the effects of maladaptive perfectionism were controlled, the direct effects of extrinsic religiosity were related to reduced negative affect and increased life satisfaction. Overall, the strongest mediator in this study of both intrinsic and extrinsic religiosity was maladaptive perfectionism, with intrinsic religiosity related to decreased maladaptive perfectionism and extrinsic religiosity related to increased maladaptive perfectionism.     

Personality Expression and Impression Formation in Online Social Networks: An Integrative Approach to Understanding the Processes of Accuracy,Impression Management and Meta‐accuracy

In this paper, we investigate personality expression and impression formation processes in online social networks (OSNs). We explore whether, when and why people accurately judge others' personalities (accuracy), successfully manage the impressions that others form of them (impression management) and accurately infer others' impressions of them (meta‐accuracy) at zero acquaintance. On the basis of targets' OSN profiles (N = 103), overall perceiver impressions were collected and compared with targets' self‐view, desired impression and meta‐perception. In addition, independent groups of thin‐slice perceivers based their personality impressions solely on one of four kinds of information within the OSN profiles (profile picture, interests field, group list and notice board), and more than 300 OSN cues (e.g. attractive person and number of friends) were coded. Results showed evidence of accuracy, impression management and meta‐accuracy, but their extent was moderated by the trait (e.g. Big Five and self‐esteem), the kind of information and the interplay of trait and information. Findings could be explained by cue expression and cue utilization processes (lens model analyses). Future prospects for studying personality impressions in online and offline environments are discussed. Copyright © 2013 European Association of Personality Psychology.

Unapocalyptic Theology: History and Eschatology in Balthasar's Theo‐Drama

In this essay, I evaluate the claim that Hans Urs von Balthasar's interpretation of trinitarian doctrine undermines the importance of history for the Christian God. Where other critics argue that the very distinction between immanent and economic Trinity robs the economy of salvation of theological significance, I contend that the underlying problem lies in how Balthasar restricts the theo‐drama to an event between heaven and earth on the cross of Golgotha. Through this limitation of God's active involvement in history to a single event, Balthasar's theo‐drama becomes an “unapocalyptic theology”, which devalues God's salvific history with the world and the biblical expectation of an eschatological end of history. Furthermore, Balthasar underplays the messianic‐political dimension of the Christian concept of salvation and thereby cements the status quo of a yet unredeemed world.
