Electrophysiological correlates of high-level perception during spatial navigation

We studied the electrophysiological basis of object recognition by recording scalp electroencephalograms while participants played a virtual-reality taxi driver game. Participants searched for passengers and stores during virtual navigation in simulated towns. We compared oscillatory brain activity in response to store views that were targets or nontargets (during store search) or neutral (during passenger search). Even though store category was solely defined by task context (rather than by sensory cues), frontal electrophysiological activity in the low frequency bands (primarily in the θ [4–8 Hz] band) reliably distinguished between the target, nontarget, and neutral store views. These results implicate low-frequency oscillatory brain activity in frontal regions as an important variable in the study of the cognitive processes involved in object recognition, categorization, and other forms of high-level perception.     

Fostering Analytic Metacognitive Processes and Reducing Overconfidence by Disfluency: The Role of Contrast Effects

Overconfidence leads to premature termination of study and, thus, to decreased performance. The aim of the present study is to improve students' monitoring and control. We assume that disfluency fosters analytic metacognitive processes and thus reduces overconfidence. However, we expect that contrast effects moderate the fluency effects on metacognitive processes because disfluency activates analytic metacognitive processes not only for disfluent but also for succeeding fluent learning material. To test our hypotheses, university students (N = 75) learned either with a fluent text first and afterward a disfluent text or with a disfluent text first and afterward a fluent text. The results show fluency effects on control, monitoring, and monitoring accuracy only when students learned with a fluent and afterward a disfluent text. Performance was worse for disfluent than for fluent texts in both conditions. Therefore, instructional settings that help students to implement accurate monitoring into better control and better performance are required. Copyright © 2017 John Wiley & Sons, Ltd.     

Relevance differently affects the truth,acceptability, and probability evaluations of “and”, “but”, “therefore”, and “if–then”

In this study, we investigate the influence of reason-relation readings of indicative conditionals and “and”/“but”/“therefore” sentences on various cognitive assessments. According to the Frege–Grice tradition, a dissociation is expected. Specifically, differences in the reason-relation reading of these sentences should affect participants’ evaluations of their acceptability but not of their truth value. In two experiments we tested this assumption by introducing a relevance manipulation into the truth-table task as well as in other tasks assessing the participants’ acceptability and probability evaluations. Across the two experiments, a strong dissociation was found. The reason-relation reading of all four sentences strongly affected their probability and acceptability evaluations, but hardly affected their respective truth evaluations. Implications of this result for recent work on indicative conditionals are discussed.     

A guideline for integrating dynamic areas of interests in existing set-up for capturing eye movement: Looking at moving aircraft

Today, capturing the behavior of a human eye is considered a standard method for measuring the information-gathering process and thereby gaining insights into cognitive processes. Due to the dynamic character of most task environments there is still a lack of a structured and automated approach for analyzing eye movement in combination with moving objects. In this article, we present a guideline for advanced gaze analysis, called IGDAI (Integration Guideline for Dynamic Areas of Interest). The application of IGDAI allows gathering dynamic areas of interest and simplifies its combination with eye movement. The first step of IGDAI defines the basic requirements for the experimental setup including the embedding of an eye tracker. The second step covers the issue of storing the information of task environments for the dynamic AOI analysis. Implementation examples in XML are presented fulfilling the requirements for most dynamic task environments. The last step includes algorithms to combine the captured eye movement and the dynamic areas of interest. A verification study was conducted, presenting an air traffic controller environment to participants. The participants had to distinguish between different types of dynamic objects. The results show that in comparison to static areas of interest, IGDAI allows a faster and more detailed view on the distribution of eye movement.     

The World Mission Conference 2018: An Approach from Germany

World Mission Conferences (WMC) have always included missionary calls and an analysis of the present‐day situation, 1 and frequently have provided important input for the debate on the mission of the churches throughout the world and in Germany. The upcoming WMC in Arusha, Tanzania, therefore raises high expectations. The following considerations attempt to sketch the subject in the context of the situation in the German church and society and to point to possible links with what is known about the programme of the WMC.     

Self-Attributed Importance of Spiritual Practices in Catholic Pastoral Workers and their Association with Life Satisfaction

Although much is known about the frequency of the spiritual activities of pastoral workers, less is known related to how important specific spiritual and existential practices are to pastoral workers personally or existentially. This part of the German Pastoral Ministry Study analyzed (1) which forms of spiritual activities were regarded as important, (2) how the perceived importance of religious practices related to frequency of engagement in spiritual practices, and (3) how these practices contributed to the life satisfaction of ordained priests and of non-ordained pastoral workers. Participants included 1826 Catholic pastoral workers, composed of 65% priests and 35% (non-ordained) pastoral assistants and parish expert workers. Prosocial-Humanistic practices scored highest in importance, followed by Gratitude/Awe, Existentialistic practices, and Religious practices; specific forms of Spiritual Mind-Body practices were not relevant. Differences in the frequency and ascribed importance of spiritual practices between ordained and non-ordained pastoral workers were identified, as well as a surprising lack of connection between religious practices and their proclaimed importance, particularly of Prosocial-Humanistic and Gratitude/Awe practices. These findings may stimulate further research into the underlying causes of these differences between priests and other pastoral workers and between the frequency and importance of spiritual practices in all groups, which in the researchers’ opinion indicate challenging inconsistencies with regard to the ideals of religious vocations.
