Counter‐Interrogation Strategies when Anticipating Questions on Intentions

The present experimental study adds to the emerging line of psycholegal research focusing on true and false intentions. It is the first to examine mock suspects' (N = 120) counter‐interrogation strategies in investigative interviews in which they anticipate questions on their intentions. As planning is an inherent part of many intentions, mock suspects were, in addition to questions on their intentions, asked a set of questions that pertained to the planning phase in which they formed their intentions. Besides ratings of the anticipation and difficulty of the questions, participants were asked to provide their principal strategy for being perceived as truthful. Both truth tellers and liars perceived the questions on the planning phase as significantly more unanticipated than the questions on their intentions. Furthermore, liars perceived the questions on the planning phase as more difficult to answer than did truth tellers. Liars and truth tellers differed with respect to their principal strategy employed for being perceived as truthful. Liars' most commonly used strategy was to stick to the cover story, whereas truth tellers' most common strategy was to be honest. The results are discussed in relation to the unanticipated questions approach and psychological concepts such as the illusion of transparency. Copyright © 2012 John Wiley & Sons, Ltd.     

Exploring perceptual processing of ASL and human actions: effects of inversion and repetition priming

In this paper, we compare responses of deaf signers and hearing non-signers engaged in a categorization task of signs and non-linguistic human actions. We examine the time it takes to make such categorizations under conditions of 180° stimulus inversion and as a function of repetition priming, in an effort to understand whether the processing of sign language forms draws upon special processing mechanisms or makes use of mechanisms used in recognition of non-linguistic human actions. Our data show that deaf signers were much faster in the categorization of both linguistic and non-linguistic actions, and relative to hearing non-signers, show evidence that they were more sensitive to the configural properties of signs. Our study suggests that sign expertise may lead to modifications of a general-purpose human action recognition system rather than evoking a qualitatively different mode of processing, and supports the contention that signed languages make use of perceptual systems through which humans understand or parse human actions and gestures more generally.     

Therapy for couples after an affair: A randomized-controlled trial

To examine the efficacy of a couples treatment approach for promoting recovery from a recently disclosed affair, 89 couples that disclosed an affair by one of the partners in the past 6 months were randomly assigned to treatment (n = 46) or to a control group that waited about 3 months for treatment (n = 43). The couples completed self-report measures (Beck Depression Inventory, Impact of Event Scale-Revised, Partnership Questionnaire) at pre- and post-treatment. Since about half of the couples dropped out for various reasons (e.g., ongoing affair, separation), we used multiple imputations to handle the missing data problem. We analyzed the dyadic data with hierarchical linear modeling in a two-level model. Significant improvements on scores of anxiety corresponded with large effect sizes for both partners. Yet significant improvements on depression scores were only found for the unfaithful partner with moderate effect size. Results suggest that the treatment can improve individual complaints, but not relationship satisfaction in a sufficient amount for both partners. Hence, future research should address how this intervention could encourage couples to maintain therapy, and how they might achieve more and sustained improvement in relationship satisfaction.     

Change occurs when body meets environment: A review of the embodied nature of development

The purpose of this paper is to outline the challenges of psychological research in addressing the mechanisms of emergence: how new behavioral patterns and cognitive abilities arise from the interaction of an organism with its environment in real time. We review some of the empirical studies on infant development with reference to Dynamical Systems accounts and relevant views such as the ecological approach to perception and action, and cover topics ranging from early motor skills to goal‐directed locomotion and to higher cognitive development. The central claim is that the results of these studies are essentially related: they suggest that there is a fundamental connection among perception, motor behavior, and cognition. In addition, we recount our attempt to re‐enact the situatedness and temporal structure of the decision‐making processes of human infants by using an autonomous robotic device. We conclude by highlighting several insights from the broad spectrum of studies looking into the embodied nature of adaptive behavior. In our view, such studies are making a profound contribution to uncovering the emergent mechanisms of intellectual and bodily activity throughout development.     

The Problem of Agency and the Problem of Accountability in Kant's Moral Philosophy

Abstract: This paper discusses the function and scope of incompatibilist or transcendental freedom in Kant's moral philosophy. The prevailing view among scholars, most notably Allison, is that the function of transcendental freedom is to enable us to articulate a first‐person conception of ourselves as rational agents involved in deliberation and choice. Thus, the scope of transcendental freedom is rational agency in general. In order to perform this function, freedom has to be merely conceivable. Pace Allison, I argue that our first‐person conception is neutral with respect to causal determinism, and that the function of transcendental freedom is to provide the metaphysical conditions of the possibility of genuine moral responsibility and perfect justice, and to get rid of moral luck. In order to perform this function, transcendental freedom has to be not just conceivable, but metaphysically real. My view suggests that we only have reason to attribute freedom to ourselves in situations in which we are aware that the moral law commands us categorically. We do not have a similar reason to believe we are free in purely prudential choices. Thus, the scope of transcendental freedom is not rational agency in general, but only moral agency.     

Aufmerksamkeitsdefizit-/Hyperaktivitätsstörung (ADHS) im Jugendalter

Attention deficit–hyperactivity disorder (ADHD) in children and adolescents is a common and severe psychiatric disorder with a prevalence between 2 and 6%. In a high percentage of cases, there is a positive family history. In almost all sufferers, persistent functional limitations that impact everyday life are observed. The prognosis for untreated ADHD is very poor, being associated with social decline, drug addiction, and delinquency. Diagnosis is complex. Typical symptoms are often “hidden”. They are age specific and are mainly associated with inattention, impulsiveness associated with aggression and delinquency, and dangerous risk-taking behavior. More than half of patients also have additional comorbid disorders. The treatment concept always includes nonpharmacological interventions, which are often supplemented with drugs.     

Different responses of two strains of chickens to different training procedures for magnetic directions

In previous conditioning experiments training domestic chickens to magnetic directions, a brown strain solved the task, whereas a white strain seemed unable to do so (Freire et al. Anim Cogn 11:547–552, 2008). To test whether this was possibly caused by loss of magnetic compass orientation in the white chickens, we analyzed the distribution of cryptochrome 1a, the candidate receptor molecule mediating magnetic compass information, in the retinae of Lohmann Browns and White Leghorns and found no difference between the two strains. Yet, subsequent training experiments replicated the former findings: Lohmann Browns used the magnetic field to find an imprinting stimulus hidden behind the screen in a specific magnetic direction, whereas White Leghorns did not solve the task. However, when we altered the training method by training also in a magnetic field with North shifted to geographic East and including a punishment for incorrect choices, the performance of White Leghorns improved to a significant preference for the expected directions. The Lohmann Browns, on the other hand, seemed frightened and chose randomly. Our results thus demonstrate the crucial role of the training method for conditioning to magnetic stimuli, with differences found even between strains of the same species.     

Using Dynamic Field Theory to extend the embodiment stance toward higher cognition

The embodiment stance emphasizes that cognitive processes unfold continuously in time, are constantly linked to the sensory and motor surfaces, and adapt through learning and development. Dynamic Field Theory (DFT) is a neurally based set of concepts that has turned out to be useful for understanding how cognition emerges in an embodied and situated system. We explore how the embodiment stance may be extended beyond those forms of cognition that are closest to sensorimotor processes. The core elements of DFT are dynamic neural fields (DNFs), patterns of activation defined over different kinds of spaces. These may include retinal space and visual feature spaces, spaces spanned by movement parameters such as movement direction and amplitude, or abstract spaces like the ordinal axis along which sequences unfold. Instances of representation that stand for perceptual objects, motor plans, or action intentions are peaks of activation in the DNFs. We show how such peaks may arise from input and are stabilized by intra-field interaction. Given a neural mechanism for instantiation, the neuronal couplings between DNFs implement cognitive operations. We illustrate how these mechanisms can be used to enable architectures of dynamic neural fields to perform cognitive functions such as acquiring and updating scene representations, using grounded spatial language, and generating sequences of actions. Implementing these DFT models in autonomous robots demonstrates how these cognitive functions can be enacted in embodied, situated systems.     

Reference-related inhibition produces enhanced position discrimination and fast repulsion near axes of symmetry

Models proposed to account for reference frame effects in spatial cognition often account for performance in some tasks well, but fail to generalize to other tasks. Here, we demonstrate that a new process account of spatial working memory--the dynamic field theory (DFT)--can bridge the gap between perceptual and memory processes in position discrimination and spatial recall, highlighting that the processes underlying spatial recall also operate in position discrimination. In six experiments, we tested two novel predictions of the DFT: first, that discrimination is enhanced near symmetry axes, especially when the perceptual salience of the axis is increased; and second, that performance far from a reference axis depends on the direction in which the second stimulus is presented. The DFT also predicts the magnitude of this direction-dependent modulation. These effects arise from reference-related inhibition in the theory. We discuss how the processes captured by the DFT relate to existing psychophysical models and operate across a diverse array of spatial tasks.
