Approaches to analysis of handwriting as a task of coordinating a redundant motor system

We consider problems of motor redundancy associated with handwriting using the framework of the uncontrolled manifold (UCM) hypothesis. Recent studies of finger coordination during force production tasks have demonstrated that the UCM-hypothesis provides a fruitful framework for analysis of multi-finger actions. In particular, it has been shown that during relatively fast force changes, finger force variance across trials is structured such that a time pattern of total moment produced by the fingers with respect to a point between the two most lateral fingers involved in the task is stabilized while the time pattern of total force may be destabilized. The findings of selective moment stabilization have been interpreted as being conditioned by the experience with everyday motor tasks that commonly pose more strict requirements to stabilization of total moment than to stabilization of total force. We discuss implications of these findings for certain features of handwriting seen in elderly, children, patients with neurological disorders, and forgers.     

Deception detection: interrogators' and observers' decoding of consecutive statements

This study is an examination of two forensically important but previously neglected issues in interpersonal deception. First, which cues do lie catchers-who have access to repeated interrogations-pay attention to in order to detect deception? Second, do face-to-face interacting interrogators differ from noninteracting observers in terms of how they perceive a suspect? After watching a staged event, 24 suspects (12 liars and 12 truth tellers) were interrogated three times over a period of 11 days. After the final interrogation, the veracity of each suspect was assessed by his or her interrogator and by 6 observers who had watched the interrogations on video only. The results of the experiment showed that consistency over time was by far the most commonly used cue for justifying veracity judgments. Critically, the predictive accuracy for this cue was alarmingly low. As opposed to results from previous research, the interrogators used verbal cues to a significantly greater extent than did the observers. Furthermore, a probing effect was shown (i.e., probed suspects were perceived as significantly more honest than nonprobed suspects). Finally, limited support for a previously reported honesty effect was obtained (i.e., that interrogators perceive suspects to be more honest than do observers).     

Creating a Self-Plagiarism Research Topic Typology through Bibliometric Visualisation

Self-plagiarism, textual recycling and redundancy seemed to be controversial and unethical; however some questions about its definition are still open. The objective in this paper presented study was to use bibliometric analysis to synthesise and visualize the research literature production and derive a typology of self-plagiarism research. Five topics emerged: Self-plagiarism, Institutional self-plagiarism, Self-plagiarism and ICT, Self-plagiarism in academic writing, Self-plagiarism in science. The state of the art topics seem to be “social medium”, “virtual world”, “face book”, “sociomateriality”, “knowledge sharing”, “open access”, “institutional repository”, “retraction” and “responsible conduct”.     

Homo Virtualis: Body,Mind, and Soul in a Virtual World

The virtual reality that stands in the center of the digital revolution is changing the bases of our lives today. This new reality is both a product of the basic human ability of imagination and an essential element of analytical psychology. The close relationship between the activity of imagination and its influence on the body is shown in research results from the oldest known prehistoric figures, dating back between 40,000–30,000 b.c.e., and the experiences derived from the work with robots at the Massachusetts Institute of Technology (MIT). Additionally, how this virtual, body-transforming power is reflected in the current ideas of the transhumanists is examined. In this perspective, the extension of physical abilities via technical skills is a necessary step in human evolution: to transfer the human mind onto a machine as a means of circumventing inherent physical limitations.

The psychodynamics of deep psychological needs, frustrations, and fears are discussed as the motors of technical development. An interpretation of this development, based on the mythological biography of the ancient god Hephaistos, is discussed as showing astonishing parallels to the characteristics of the digital revolution and the transhumanist ideas. Thus, Hephaistos can be understood as an archetypal manifestation of those impulses from the collective unconscious that are significantly affecting our present time. The potentialities as well as the dark sides that are hidden behind such “hephaistic” solutions to deep inner psychological and spiritual conflicts are explored.     

Argumentative Patterns in the Political Domain: The Case of European Parliamentary Committees of Inquiry

In this paper, close attention is paid to the argumentative patterns resulting from combining pragmatic argumentation in which a recommendation is made with arguments in which the majority is invoked. I focus on such argumentative patterns as employed by European parliamentary committees of inquiry conducting inquiries into the activity of the Equitable Life Assurance Society. By incorporating legal and political insights about the activity of these parliamentary committees of inquiry into a pragma-dialectical argumentative approach, an analysis will be given of the selected argumentative pattern. This analysis will reveal which standpoints are supported by which arguments and how these arguments relate to each other to increase the acceptability of the recommendation made. In addition, the analysis will explain the arguer’s argumentative choices in the pattern employed.     

Experience of Norwegian Female BRCA1 and BRCA2 Mutation-Carrying Participants in Educational Support Groups: a Qualitative Study

Women identified as BRCA1 and BRCA2 mutation carriers are advised to manage their cancer risk through intensive screening programs and/or by undergoing risk-reducing surgery. The aim of this study was to explore and describe the experiences of female BRCA1/2 mutation carriers living with cancer risk and their experiences with participation in educational support groups (ESG). This qualitative study enrolled 17 (10 + 7) ESG participants in two different ESGs. The focus group interviews were performed immediately prior to and following two ESGs. The data were analyzed using John Knodel’s (1993) practical approach. Three main themes were identified; the women’s expectation and experience with ESG, the feeling of loneliness and isolation, and the feelings of living with “something else.” In this paper we have focused on one of the main themes- the women’s expectation and experience with ESG. This main theme presents four subthemes: the women’s need for unambiguous, clear and unified information from health professionals, the need for social support, the important role of the patient representative, and increased knowledge potentially raising concern. Participation in an ESG for women with BRCA1 and BRCA2 mutations can provide relevant information and support in the decision-making process related to risk-reducing surgery.     

Contrasting accounts of direction and shape perception in short-range motion: Counterchange compared with motion energy detection

It has long been thought (e.g., Cavanagh & Mather, 1989) that first-order motion-energy extraction via space-time comparator-type models (e.g., the elaborated Reichardt detector) is sufficient to account for human performance in the short-range motion paradigm (Braddick, 1974), including the perception of reverse-phi motion when the luminance polarity of the visual elements is inverted during successive frames. Human observers’ ability to discriminate motion direction and use coherent motion information to segregate a region of a random cinematogram and determine its shape was tested; they performed better in the same-, as compared with the inverted-, polarity condition. Computational analyses of short-range motion perception based on the elaborated Reichardt motion energy detector (van Santen & Sperling, 1985) predict, incorrectly, that symmetrical results will be obtained for the same- and inverted-polarity conditions. In contrast, the counterchange detector (Hock, Schöner, & Gilroy, 2009) predicts an asymmetry quite similar to that of human observers in both motion direction and shape discrimination. The further advantage of counterchange, as compared with motion energy, detection for the perception of spatial shape- and depth-from-motion is discussed.     

Early drinking onset: A study of prevalence and determinants among 13‐year‐old adolescents in Norway

Early drinking onset is associated with different psychosocial adjustment problems among adolescents. The aim of this study was to assess determinants associated with early drinking and to identify factors predicting early drinking onset among adolescents. The study included 1,550 eighth‐graders with a mean age of 13.5 years from 41 schools. A total of 24% (boys 29%, girls 19%) had ever drunk alcohol, while 14% had drunk some alcohol in the last 30 days. Further, early drinking was associated with gender, religion, school performance, smoking and bullying in the bivariate tests. Predictors of early drinking onset were identified by generalized linear mixed models with two multivariable models created. The first model included social and environmental variables. Entering intentions, expectancies, attitudes and norms into the multivariable analysis resulted in a significant improvement of the model fit constituting 86% in the second model. The percentage correctly classified those (56%) who had been drinking in the second model which was two times higher compared to the first model. Gender, religion and smoking emerged as significant predictors of drinking in both models.     

Facilitating memory‐based lie detection in immediate and delayed interviewing: The role of mnemonics

We experimentally investigated how different mnemonic techniques employed in an interview conducted immediately after an event affected truth tellers' and liars' responses when they were interviewed again after a 2‐week delay. We also compared how verbal accounts changed over time within truth tellers and liars, and how consistent both groups were. Participants (n = 143) were shown a mock intelligence operation video and instructed either to tell the truth or lie about its contents in two interviews, one of which was immediately after watching the video and the other after a 2‐week delay. In the immediate interview, they were asked to provide a free recall and then asked to provide further information via one of three mnemonics: context reinstatement, sketch, or event‐line. In the delayed interview, they were asked to provide only a free recall. Truth tellers reported more visual, spatial, temporal, and action details than did liars both immediately and after a delay. Truth tellers experienced more of a decline in reporting details after a delay than did liars, and this decline was affected by the mnemonic used. Truth tellers thus showed, more than liars, patterns of reporting indicative of genuine memory decay. Liars produced patterns of a “stability bias” instead. Truth tellers and liars were equally consistent between their immediate and delayed statements.
