Perceived reality of visually mediated hazards and beliefs about risk

The aim of the present paper was to explore whether beliefs about risk are affected by media content authenticity as perceived by the viewers. A total of 69 participants were shown either a fictional or a reality‐based film on nuclear power. They rated risk perception prior to and after the film as well as ten days later, reactions to the film experience, and items of the scale for Need for Cognition. Results showed that individuals high in need for cognition were more accurate in their judgment of the authenticity of films, but were as influenced in their risk perception as their counterparts. Nuclear risk ratings showed a significant and large increase immediately upon the film session, but had resumed pre‐film level when measured ten days later. The potential influence of perceived content authenticity on risk perception is discussed in light of increasingly transformed patterns of media consumption.

Congruence of actual and retrospective reports of precompetition affect and anxiety for young volleyball players

The current study examined the accuracy of retrospective recall of affect and competitive anxiety in 38 youth beach volleyball players, who were randomly assigned into two equal groups: participants who watched a video of their precompetition preparation before responding to the items, and players who did not watch a videotape. All completed the modified competitive State Anxiety Inventory-2 1 hr., and the affect grid 5 min., before a competition and again 2 days later. Accuracy in recalling anxiety and affect by these players was significant in both conditions (rs = .59-.76 and .41-.59, respectively). However, in the video condition, item responses showed markedly higher percentages of agreement for the Somatic and Cognitive Anxiety subscales and the affect grid than those for the no-video condition (52.6-78.9% and 36.8-52.6%, respectively). Analysis of variance indicated that watching a video for precompetition preparation improved the accuracy of retrospective recall of anxiety and arousal. Video feedback of performance increased the accuracy of retrospective report of affect and anxiety in these young athletes.     

Influence of personal therapy on learning and development of psychotherapeutic skills

The aim of the present study was to investigate psychodynamic psychotherapists’ experience of the influence of personal therapy on professional growth during training with a focus on the acquisition of knowledge and the development of psychotherapeutic skills. Thematic analysis was conducted on interviews with former students (N=10) at two training institutes for psychoanalytic psychotherapy. The resulting theme “professional subjectivity” indicated that personal therapy was experienced as having a positive effect on learning and growth of professional skill by facilitating the development of a theory- and knowledge-based professional subjectivity, a personally founded, professional attitude. Important elements of this development are “shared experience,” “personal influence,” and “knowledge integration.” The emergence of professional subjectivity proved to be an important factor in terms of professional advancement for future psychotherapists. Finding and relating to their own subjectivity was crucial in the process of developing a personally founded, professional attitude in the clinical work.     

Old Foundations for the Logic of Agency and Action

The paper presents an infinite hierarchy of sound and complete axiomatic systems for Two-Dimensional Modal Tense Logic with Historical Necessity, Agents and Acts. A main novelty of these logics is their capacity to represent formally (i) basic action-sentences asserting that such and such an act is performed/omitted by an agent, as well as (ii) causative action-sentences asserting that by performing/omitting a certain act, an agent causes that such and such a state-of-affairs is realized (e.g. comes about/ceases/remains/remains absent). We illustrate how the formal machinery of our systems can be used to reconstruct a number of interesting ideas in the Logic of Agency and Action that have been proposed by authors like von Wright, von Kutschera, Belnap and Segerberg.     

The legacy of the silver methods and the new anatomy of the basal forebrain: implications for neuropsychiatry and drug abuse

The first part of the paper highlights the remarkable legacy of the silver methods, with special emphasis on the travails and opportunities offered by the various Nauta methods and their modifications. When the tracer methods based on axoplasmic flow were introduced in the early 1970s, they were exploited on a backdrop of a basic anatomical framework, which had already been established through the tracing of the major CNS pathways by the aid of the silver methods, especially the widely used Nauta-Gygax methods and their modifications. Some of the silver methods that were developed in the late 1960s for the staining of degenerating boutons (e.g. the Fink-Heimer method and de Olmos cupric silver method) provided the necessary technical improvements that eventually led to a new and more productive way to look at the basal forebrain functional/anatomical organization; if it was not for the silver methods, we would in all likelihood still be promoting the nebulous notion of the substantia innominata rather than the concepts of the ventral striatopallidal system and the extended amygdala. The discovery and elaboration of these two macroanatomical systems symbolize what might deservedly be called the "new anatomy" of the basal forebrain. Following a review of the critical experiments which led to the development of the new anatomy of the basal forebrain, its topography in the human is reviewed in drawings of an abbreviated series of coronal sections. The discovery of the ventral striatopallidal system and its thalamic projection to the mediodorsal thalamus rather than to the ventral anterior-ventral lateral thalamic complex ushered in the idea of parallel cortico-subcortical reentrant circuits, which to a large extent has replaced the limbic system as a theoretical framework for neuropsychiatric disorders. The extended amygdala, which appears as a large ring formation around the internal capsule, is still controversial in some quarters, although it is slowly but surely making its way into the general neuroscience literature, especially in the field of addictive disorders. The ventral striatopallidal system and the extended amygdala are interwoven in a complex fashion with the basal nucleus of Meynert within the basal forebrain. Together, these three systems represent important output channels for so-called "limbic" forebrain regions, especially orbitomedial prefrontal cortex and medial temporal lobe structures, which are increasingly implicated in major neuropsychiatric disorders.     

Skin conductance response in Swedish United Nations soldiers exposed to fear-relevant stimuli

The aim of this study was to investigate whether there was a difference in skin conductance response between 2 groups of military personnel when exposed to emotionally neutral and charged stimuli. The 2 groups were a combat experience group (n = 10) with prior experience of emotionally charged war situations and a comparison group (n = 10) with no such experience. Results showed that the comparison group reacted more strongly to exposure to both charged and neutral pictures than did the combat experience group, regardless of exposure time. The results are discussed in terms of emotional numbing and differences in anxiety state between the 2 groups.     

Preattentive bias for snake words in snake phobia?

Stroop interference and skin conductance responses (SCRs) for words related to snakes, spiders, flowers, and mushrooms were studied in a group of women (n=40) with snake phobia who were randomised to a stress or no-stress condition. The 21 low-stress snake phobics showed Stroop interference for unmasked (but not for masked) snake words, compared with 21 age- and sex-matched controls. Stroop interference was not significantly different between high-stress and low-stress snake phobics. No support for stronger SCRs for masked snake words was found in snake phobics in a lexical decision task with masked presentations of the same words. The lack of a masked Stroop interference in snake phobics suggests a possible difference in cognitive-emotional mechanisms underlying specific phobia vs. other anxiety disorders that deserves further investigation.     

The Undecidability of Quantified Announcements

This paper demonstrates the undecidability of a number of logics with quantification over public announcements: arbitrary public announcement logic (APAL), group announcement logic (GAL), and coalition announcement logic (CAL). In APAL we consider the informative consequences of any announcement, in GAL we consider the informative consequences of a group of agents (this group may be a proper subset of the set of all agents) all of which are simultaneously (and publicly) making known announcements. So this is more restrictive than APAL. Finally, CAL is as GAL except that we now quantify over anything the agents not in that group may announce simultaneously as well. The logic CAL therefore has some features of game logic and of ATL. We show that when there are multiple agents in the language, the satisfiability problem is undecidable for APAL, GAL, and CAL. In the single agent case, the satisfiability problem is decidable for all three logics.     

Recipient Design in Communicative Pointing

A long‐standing debate in the study of human communication centers on the degree to which communicators tune their communicative signals (e.g., speech, gestures) for specific addressees, as opposed to taking a neutral or egocentric perspective. This tuning, called recipient design, is known to occur under special conditions (e.g., when errors in communication need to be corrected), but several researchers have argued that it is not an intrinsic feature of human communication, because that would be computationally too demanding. In this study, we contribute to this debate by studying a simple communicative behavior, communicative pointing, under conditions of successful (error‐free) communication. Using an information‐theoretic measure, called legibility, we present evidence of recipient design in communicative pointing. The legibility effect is present early in the movement, suggesting that it is an intrinsic part of the communicative plan. Moreover, it is reliable only from the viewpoint of the addressee, suggesting that the motor plan is tuned to the addressee. These findings suggest that recipient design is an intrinsic feature of human communication.
