Medical Students’ Efforts to Integrate and/or Reclaim Authentic Identity: Insights from a Mask-Making Exercise

Medical students’ mask-making can provide valuable insights into personal and professional identity formation and wellness. A subset of first- and second-year medical students attending a medical school wellness retreat participated in a mask-making workshop. Faculty-student teams examined student masks and explanatory narratives using visual and textual analysis techniques. A quantitative survey assessed student perceptions of the experience. We identified an overarching theme: “Reconciliation/reclamation of authentic identity.” The combination of nonverbal mask-making and narrative offers rich insights into medical students’ experience and thinking. This activity promoted reflection and self-care, while providing insight regarding personal and professional development.     

The effect of motivation on working memory: an fMRI and SEM study

This study investigated the effective connectivity between prefrontal regions of human brain supporting motivational influence on working memory. Functional magnetic resonance imaging (fMRI) and structural equation modeling (SEM) were used to examine the interaction between the lateral orbitofrontal (OFC), medial OFC, and dorsolateral prefrontal (DLPFC) regions in the left and right hemisphere during performance of the verbal 2-back working memory task under two reinforcement conditions. The "low-motivation" condition was not associated with monetary reinforcement, while the "high-motivation" condition involved the probability of winning a certain amount of money. In the "low-motivation" condition, the OFC regions in both hemispheres positively influenced the left DLPFC activity. In the "high-motivation" condition, the connectivity in the network including the right OFC regions and left DLPFC changed from positive to negative, whereas the positive connectivity in the network composed of the left OFC and left DLPFC became slightly enhanced compared with the "low-motivation" condition. However, only the connection between the right lateral OFC and left DLPFC showed a significant condition-dependent change in the strength of influence conveyed through the pathway. This change appears to be the functional correlate of motivational influence on verbal working memory.     

Logical Modes of Attack in Argumentation Networks

This paper studies methodologically robust options for giving logical contents to nodes in abstract argumentation networks. It defines a variety of notions of attack in terms of the logical contents of the nodes in a network. General properties of logics are refined both in the object level and in the metalevel to suit the needs of the application. The network-based system improves upon some of the attempts in the literature to define attacks in terms of defeasible proofs, the so-called rule-based systems. We also provide a number of examples and consider a rigorous case study, which indicate that our system does not suffer from anomalies. We define consequence relations based on a notion of defeat, consider rationality postulates, and prove that one such consequence relation is consistent.     

Beyond Political Theology and its Liquidation: From Theopolitical Monotheism to Trinitarianism

One of the central theological challenges facing Erik Peterson was to help the mid‐twentieth century Catholic Church define its relationship with the wider world. He responded by advancing a distinctive understanding of the ‘polis.’ In this essay, I critically analyze Peterson's central and perhaps best known proposal about how the Church ought to negotiate the modern world — encapsulated in his expression, the ‘liquidation of political theology.’ I contend that Peterson's proposal is not congruent with a right understanding of patristic trinitarian monarchy, although a view that stands in sharp contrast to that of Carl Schmitt. Notwithstanding the effectiveness of Peterson's critique of Schmitt's political theology, I argue that Peterson nonetheless fails in his exposition of the thought of Gregory of Nazianzus and therefore in his interpretation of the role of the Church in what we have learned to call the ‘political’ and the ‘social.’ I conclude by outlining several ways that the Church today might take up the challenge of regaining a truly political thought, a new ekklesioteia, nourished by the monarchy of the triune God.     

Hebb repetition effects for non-verbal visual sequences: determinants of sequence acquisition

We report four experiments premised upon the work of Horton et al. [(2008). Hebb repetition effects in visual memory: The roles of verbal rehearsal and distinctiveness. Quarterly Journal of Experimental Psychology, 61(12), 1769–1777] and Page et al. [(2013). Repetition-spacing and item-overlap effects in the Hebb repetition task. Journal of Memory and Language, 69(4), 506–526], and explore conditions under which the visual Hebb repetition effect is observed. Experiment 1 showed that repetition learning is evident when the items comprising the non-repeated (filler) sequences and the repeated (Hebb) sequences are different (no-overlap). However, learning is abolished when the filler and Hebb sequences comprise the same items (full-overlap). Learning of the repeated sequence persisted when repetition spacing was increased to six trials (Experiment 2), consistent with that shown for verbal stimuli (Page et al., 2013). In Experiment 3, it was shown that learning for the repeated sequence is accentuated when the output motor response at test is also repeated for the Hebb sequence, but only under conditions of no-overlap. In Experiment 4, repetition spacing was re-examined with a repeated motor output response (a closer methodological analogue to Page et al., 2013). Under these conditions, the gradient of Hebb repetition learning for six trial repetition intervals was markedly similar to that for three trial intervals. These findings further support the universality of the Hebb repetition effect across memory and are discussed in terms of evidence for amodality within-sequence memory.     

Combining mixture distribution and multidimensional IRTree models for the measurement of extreme response styles

Personality constructs, attitudes and other non-cognitive variables are often measured using rating or Likert-type scales, which does not come without problems. Especially in low-stakes assessments, respondents may produce biased responses due to response styles (RS) that reduce the validity and comparability of the measurement. Detecting and correcting RS is not always straightforward because not all respondents show RS and the ones who do may not do so to the same extent or in the same direction. The present study proposes the combination of a multidimensional IRTree model with a mixture distribution item response theory model and illustrates the application of the approach using data from the Programme for the International Assessment of Adult Competencies (PIAAC). This joint approach allows for the differentiation between different latent classes of respondents who show different RS behaviours and respondents who show RS versus respondents who give (largely) unbiased responses. We illustrate the application of the approach by examining extreme RS and show how the resulting latent classes can be further examined using external variables and process data from computer-based assessments to develop a better understanding of response behaviour and RS.     

Über den Einfluß des Schlafens auf das Wiedererkennen

Ohne ZusammenfassungFür diese Versuche, die in der Zeit von August 1926 bis Juni 1927 stattfanden, stellten sich 14 Vpn. (Damen, Herren und Schüler im Alter von 14–16 Jahren) freundlicherweise zur Verfügung. Ebenso 12 Schüler zu den Vorversuchen. Ihnen allen sei an dieser Stelle für ihre Mühe und Geduld herzlich gedankt. Dank schulde ich auch meiner Frau für ihre Hilfe bei der Unterbringung der Vpn. während der Nachtversuche. Vor allem aber danke ich den Herren Prof. Köhler und Lewin, Berlin, für die Anregung und Förderung der Untersuchung auf das herzlichste.     

The Set of Fear Inducing Pictures (SFIP): Development and validation in fearful and nonfearful individuals

Emotionally charged pictorial materials are frequently used in phobia research, but no existing standardized picture database is dedicated to the study of different phobias. The present work describes the results of two independent studies through which we sought to develop and validate this type of database—a Set of Fear Inducing Pictures (SFIP). In Study 1, 270 fear-relevant and 130 neutral stimuli were rated for fear, arousal, and valence by four groups of participants; small-animal (N = 34), blood/injection (N = 26), social-fearful (N = 35), and nonfearful participants (N = 22). The results from Study 1 were employed to develop the final version of the SFIP, which includes fear-relevant images of social exposure (N = 40), blood/injection (N = 80), spiders/bugs (N = 80), and angry faces (N = 30), as well as 726 neutral photographs. In Study 2, we aimed to validate the SFIP in a sample of spider, blood/injection, social-fearful, and control individuals (N = 66). The fear-relevant images were rated as being more unpleasant and led to greater fear and arousal in fearful than in nonfearful individuals. The fear images differentiated between the three fear groups in the expected directions. Overall, the present findings provide evidence for the high validity of the SFIP and confirm that the set may be successfully used in phobia research.
