Development and Psychometric Characteristics of the Dissociation Tension Scale

The newly developed Dissoziations-Spannungs-Skala (Dissociation Tension Scale; DSS) is a self-rating instrument for the assessment of psychological and somatoform dissociative features (ranging from normal up to pathological) as well as aversive inner tension occurring within the past 7 days. The DSS contains 21 items assessing dissociative symptoms and 1 additional item assessing aversive inner tension. Ratings are made on a time-oriented scale ranging from 0% (never) to 100% (constantly). We measured the psychometric qualities of the DSS in a total of 294 patients and healthy controls. Internal consistency of the DSS was high (Cronbach's α = .92; Gutmann's split-half r = .92). We found good support for convergent, discriminant, and differential validity. There was clear evidence for the DSS being a sensitive instrument for the assessment of changing symptomatology. Assessment of dissociation and other psychopathological features over the same period of time are now possible.     

Transculturality and tradition - renewing the continuous in late modernity

The status and sovereignty of Jerusalem remains one of the most difficult, not to say the most difficult issue to be resolved before a lasting peace can arrive to the Middle East region. This article assumes that any solution to the Jerusalem-issue should be strongly accompanied by a shared vision of it among Jews, Christians and Muslims. In order to explore and elucidate the religious importance and reconciliatory potential of Jerusalem, selected writings by the British scholar and Anglican bishop Kenneth Cragg are examined in light of metaphorical theory (Lakoff &; Johnson). The article demonstrates how the theological and interreligious elasticity of Cragg's approach related to core issues within Christian teaching, and in conversation with the Jewish and Islamic tradition, exhibits an attempt at negotiation and expansion of the meaning of Jerusalem. Such attempts are surely needed if this central metaphor is to be shared among people and traditions with high stakes in the Holy City.     

Investigation of psycho-physiological interactions between patient and therapist during a psychodynamic therapy and their relation to speech using in terms of entropy analysis using a neural network approach

In the present contribution we investigate in an exemplary single-case study the behavior of psycho-physiological variables in psychotherapy sessions. The values are measured continously during a single session at the same time for both patient and therapist. The analysis of the data is done using an artificial neural network approach for non-linear principal component analysis and faithful data representation/visualization and compression required for subsequent process analysis. The used network (growing self-organizing map, GSOM) thereby uses a kernel smoothing for improved data density estimation. In this way, we are able to generate an entropy model of psycho-physiological variability detecting emotionally instable phases during the therapy process. We relate our finding to results obtained by speech analysis of the therapy sessions according to the cycle model invented by Mergenthaler. Thus, we get preliminary suggestions how psycho-physiological reactions are related to the therapeutic process.     

Multisensory identification of natural objects in a two-way crossmodal priming paradigm

The question of how vision and audition interact in natural object identification is currently a matter of debate. We developed a large set of auditory and visual stimuli representing natural objects in order to facilitate research in the field of multisensory processing. Normative data was obtained for 270 brief environmental sounds and 320 visual object stimuli. Each stimulus was named, categorized, and rated with regard to familiarity and emotional valence by N=56 participants (Study 1). This multimodal stimulus set was employed in two subsequent crossmodal priming experiments that used semantically congruent and incongruent stimulus pairs in a S1-S2 paradigm. Task-relevant targets were either auditory (Study 2) or visual stimuli (Study 3). The behavioral data of both experiments expressed a crossmodal priming effect with shorter reaction times for congruent as compared to incongruent stimulus pairs. The observed facilitation effect suggests that object identification in one modality is influenced by input from another modality. This result implicates that congruent visual and auditory stimulus pairs were perceived as the same object and demonstrates a first validation of the multimodal stimulus set.     

Neural substrates of successful working memory and long-term memory formation in a relational spatial memory task

Working memory (WM) tasks may involve brain activation actually implicated in long-term memory (LTM). In order to disentangle these two memory systems, we employed a combined WM/LTM task, using a spatial relational (object-location) memory paradigm and analyzed which brain areas were associated with successful performance for either task using fMRI. Critically, we corrected for the performance on the respective memory task when analyzing subsequent memory effects. The WM task consisted of a delayed-match-to-sample task assessed in an MRI scanner. Each trial consisted of an indoor or outdoor scene in which the exact configuration of four objects had to be remembered. After a short delay (7–13 s), the scene was presented from a different angle and spatial recognition for two objects was tested. After scanning, participants received an unexpected subsequent recognition memory (LTM) task, where the two previously unprobed objects were tested. Brain activity during encoding, delay phase and probe phase was analyzed based on WM and LTM performance. Results showed that successful WM performance, when corrected for LTM performance, was associated with greater activation in the inferior frontal gyrus and left fusiform gyrus during the early stage of the maintenance phase. A correct decision during the WM probe was accompanied by greater activation in a wide network, including bilateral hippocampus, right superior parietal gyrus and bilateral insula. No voxels exhibited supra-threshold activity during the encoding phase, and we did not find any differential activity for correct versus incorrect trials in the WM task when comparing LTM correct versus LTM incorrect trials.     

Tactile perception of thermal diffusivity

The thermal diffusivity of an object is a parameter that controls the rate at which heat is extracted from the hand when it touches that object. It is an important feature for distinguishing materials by means of touch. In order to quantitatively describe the ability of human observers to discriminate between materials on the basis of heat extraction rate, we conducted an experiment in which this heat extraction was performed in a controlled way. In different conditions, subjects were repeatedly asked to select from two stimuli the one that cooled faster. The discrimination threshold was around 43% of the extraction rate. A rate that was twice as slow also yielded twice the absolute threshold. When we halved the temperature difference between the beginning and end of the stimulus, the threshold did not change as much. In separate experiments, we investigated the different cues that were available in the stimulus: initial cooling rate and end temperature. Both cues were used for discrimination, but cooling rate seemed to be the most important.     

Christian and Political Conservatism Predict Opposition to Sexual and Gender Minority Rights through Support for Christian Hegemony

Although significant strides have been made for sexual and gender minority (SGM) rights in the United States, there continues to be opposition to SGM rights from many conservative Christians and political conservatives. In this study, we investigate this opposition by examining support for Christian hegemony (i.e., the idea that Christianity should be the norm and Christians should be in power in the United States) and unawareness of Christian privilege (i.e., unearned advantages for Christians) as religiopolitical variables that help to explain the association between Christian and political conservatism and opposition to a host of SGM rights (same-sex marriage, same-sex adoption, nondiscrimination policies in jobs and housing for SGMs, and bills regarding transgender public bathroom use). Based on structural equation modeling analysis with heterosexual cisgender Christian (n = 688) and Areligious (n = 327) students, we demonstrate that support for Christian hegemony and unawareness of Christian privilege help to explain the association between Christian and political conservatism and opposition to SGM rights. These findings advance our understanding of a new type of religious-based variable focused on religious power and privilege to help understand conservative religious and political opposition to SGM rights. Limitations, implications, and directions for future research also are discussed.
