Material properties determine how force and position signals combine in haptic shape perception

When integrating estimates from redundant sensory signals, humans seem to weight these estimates according to their reliabilities. In the present study, human observers used active touch to judge the curvature of a shape. The curvature was specified by positional and force signals: When a finger slides across a surface, the finger's position follows the surface geometry (position signal). At the same time, it is exposed to patterns of forces depending on the gradient of the surface (force signal; Robles-de-la-Torre, G., & Hayward, V. (2001). Force can overcome object geometry in the perception of shape through active touch. Nature, 412, 445-448). We show that variations in the surface's material properties (compliance, friction) influence the sensorily available position and force signals, as well as the noise associated with these signals. Along with this, material properties affect the weights given to the position and force signals for curvature judgements. Our findings are consistent with the notion of an observer who weights signal estimates according to their reliabilities. That is, signal weights shifted with the signal noise, which in the present case resulted from active exploration.     

Micro-position effects in visual short term memory

Short-term memory for visually presented eight-digit numbers was tested in a forced recall, read-and-dial task. The digits were presented non-grouped or grouped in 2+2+2+2 or 2+3+3 digit formats. Spatial grouping enhanced memory performance and produced local discontinuities in the serial position curves related to grouping format. These micro-position effects are explained in terms of the relative spatial distinctiveness of individual digits.     

Motivational climate, achievement goals, perceived sport competence, and involvement in physical activity: structural and mediator models

Students (N=231) were tested on involvement in physical activity, motivational climate, perceived sport competence, and goal orientations. Multiple regression, partial correlation, and LISREL analyses indicated that mastery goal adoption is positively correlated with a mastery climate. Performance-approach goal adoption is positively correlated with a performance climate. Mastery climate, mastery goal, and perceived sport competence are all positively correlated with involvement in physical activity. LISREL analyses supported three mediational hypotheses: (I) the positive correlation between the performance-approach goal and involvement in physical activity is mediated by (high) perceived sport competence, (II) the negative correlation between the performance-avoidance goal and involvement in physical activity is mediated by (low) perceived sport competence, (III) the positive correlation between mastery climate and involvement in physical activity is mediated by (high) mastery goal orientation. An alternative structural model with perceived competence as the last latent construct in the path was also tested.     

Bedeutung des Intelligenzquotienten für die Feststellung des Eingangsmerkmals Schwachsinn im Sinne der §§ 20, 21 StGB

Disorders in cognitive capacity, as defined in § 20 of the German legal code, are responsible for a relevant proportion of the population sentenced to treatment in forensic psychiatry in Germany. Historically one of the first conditions for diminished culpability, it refers primarily to the level of cognitive functioning. In routine psychiatric treatment of people with intellectual disability other aspects, such as emotional and social development became more and more relevant. This article explains that these aspect should be more involved in the process of forensic assessment or at least give rise to discussion and makes proposals for a modification of exculpation criteria due to the German legal code.     

Pilgrimage today: the meaning-making potential of ritual

Pilgrimage on the Road to Santiago is flourishing, even in late modern times characterised by detraditionalisation, individualism and pluralism. A large number of these pilgrims is either not explicitly religious at all, or only moderately religious. Why, then, do they submit to this ancient Christian ritual, and what are the psychological consequences? After a short introduction to the study of implicit religiosity and different perspectives on rituals from the past to today, current research on pilgrimage is reviewed and pilgrimage to Santiago is analysed as a personal ritual from a perspective of implicit religiosity. In the psychological theory of implicit religiosity, rituals are identified as one of three universal religious structures (along with myths and experiences of transcending) with strong meaning-making potential. Personal rituals are defined as formalised patterns of action, pointing beyond the actual event to a particular meaning imbued by the actor. Data from 85 pilgrims on the Road to Santiago are presented. Motives for peregrination, base-line sources of meaning, experienced meaningfulness and crises of meaning are reported, as well as changes in sources of meaning, meaningfulness and crises of meaning immediately after the pilgrimage and four months later. The majority of pilgrims (about two third) is motivated by a “need for clarification.” Multidimensional scaling shows that pilgrims either travel for explicitly religious reasons (conviction) or in search of clarification (quest); they either draw motivation from vertical transcendence (religiosity or spirituality) or from apparently purely secular reasons, such as athletic challenge. Religious and spiritual motives are mostly reported by highly religious individuals. A need for clarification is primarily stated by individuals who suffer from a crisis of meaning. Crises of meaning are significantly more frequent among pilgrims before the journey than in the general population. For the entire sample of pilgrims, the meaning-making potential of pilgrimage is supported by the data. Directly after the journey, as well as four months later, pilgrims experience life as significantly more meaningful, and crises of meaning are overcome. Pilgrims also report a strengthened commitment to vertical selftranscendence, horizontal selftranscendence and selfactualisation. These changes occur independently of the motivation for pilgrimage.     

Framing fast and slow: a dual processing account of multimodal framing effects

ABSTRACT

Human reasoning can be characterized by a continuum anchored by two extremes: fast, automatic, and emotional processing on the one side; versus slow, controlled and rational processing on the other. Despite theoretical linkages, no studies have empirically connected these types of information processing with the mechanisms of multimodal (visual and textual) media effects. We employ tools from dual processing theories in a framing effects paradigm to test whether the effects of news visuals and text take place via relatively more automatic and controlled information processing, respectively. To do so, we combine experimental manipulations and individual differences data collected across two experiments using different political issues. Results from experimental manipulations provide converging evidence for the distinct processing of visuals and text. Individual differences data paint a more nuanced picture, suggesting that the processing of multimodal news frames does not always conform to a simple automatic-controlled dichotomy.     

“If I Didn't Have My Faith I Would Have Killed Myself!”: Spiritual Coping in Patients Suffering From Schizophrenia

Spirituality, religiousness, and existential thought were qualitatively investigated in six patients suffering from schizophrenia spectrum disorders. The present study is a deepening of a recently published quantitative investigation by Danbolt, Møller, Lien, and Hestad (2011) Danbolt, L., Møller, P., Lien, L. and Hestad, K. 2011. The personal significance of religiousness and spirituality in patients with schizophrenia. The International Journal for the Psychology of Religion, 21: 145–158. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]. The patients in the present study were chosen on the basis of diversity as to how they experienced their spirituality to be of significance when coping with their disorder. The informants displayed many signs of spiritual struggle and transitional spiritual coping strategies, all of which seemed to be linked to hallucinatory experiences. Even though their spirituality met the criteria of religious delusions, the patients described their spirituality to have vital importance. The informants showed little spiritual preknowledge and seemed to be left alone without any clerical support in their spiritual struggle. This may underline the importance of including spiritual issues in the treatment of these patients.
