generating coherent presentations employing textual and Visual Material
Artificial Intelligence Review, 1995Co-Authors: Elisabeth Andre, Thomas RistAbstract:The objective of the work described in this paper is the development of an intelligent generation system which is able to combine textual and Visual Material. As coherent presentations cannot be generated by simply merging verbalization and Visualization results into multimedia output, the processes for content determination, medium selection and content realization in different media have to be carefully coordinated. We first show that multimedia presentations and pure text follow similar structuring principles. Based on this insight, we sketch how techniques for planning text and discourse can be generalized to allow the structure and contents of multimedia communications to be planned as well. In particular, we explain how our approach handles the crucial task of process coordination.

evidence for an attentional bias for washing and checking relevant stimuli in obsessive compulsive disorder
Journal of The International Neuropsychological Society, 2009Co-Authors: Steffen Moritz, Adrian Von Muhlenen, Sarah Randjbar, Susanne Fricke, Lena JelinekAbstract:There is equivocal evidence whether or not patients with obsessive-compulsive disorder (OCD) share an attentional bias for concern-related Material and if so, whether this reflects hypervigilance towards or problems to disengage from disorder-related Material. In a recent study, we failed to detect an attentional bias in OCD patients using an emotional variant of the inhibition of return (IOR) paradigm containing OCD-relevant and neutral words. We reinvestigated the research question with a more stringent design that addressed potential moderators. A new IOR paradigm was set up using Visual stimuli. Forty-two OCD patients and 31 healthy controls were presented with neutral (e.g., cup), anxiety-relevant (e.g., shark), checking-relevant (e.g., broken door), and washing-relevant (e.g., dirty toilet) cue pictures at one of two possible locations. Following a short or long interval sensitive to automatic versus controlled processes, a simple target stimulus appeared at either the cued or the uncued location. OCD patients responded significantly slower to targets that were preceded by an OCD-relevant cue. Results lend support to the claim that OCD patients share a processing abnormality for concern-related Visual Material.

words may not be enough no increased emotional stroop effect in obsessive compulsive disorder
Behaviour Research and Therapy, 2008Co-Authors: Steffen Moritz, Sarah Randjbar, Susanne Fricke, Benny Kristin Fischer, Birgit Hottenrott, Michael Kellner, Lena JelinekAbstract:Conflicting evidence has been obtained whether or not patients diagnosed with obsessive-compulsive disorder (OCD) share an attentional bias towards disorder-related stimuli. Some of these inconsistencies can be accounted for by suboptimal stimuli selection. In consideration of the heterogeneity of OCD, we investigated Stroop interference effects for two classes of OCD items (i.e., washing and checking) in 23 OCD patients and 23 healthy controls. In order to cover prevalent OCD concerns, item compilation was based on experts' appraisals. Patients neither displayed greater immediate as well as delayed Stroop interference nor any bias for OCD and subtype-congruent stimuli. On the contrary, for washing-related items, OCD patients, and here especially washers, displayed facilitation relative to healthy controls. Although the present study at first sight refutes the notion of an attentional bias in OCD in contrast to other anxiety disorders, several potential moderators need to be considered before this account is ultimately dismissed. In particular, an attentional bias may only be elicited using Visual Material that is more attention-grabbing than verbal stimuli. Finally, blockwise instead of random item administration and greater consideration of individual relevance may be crucial prerequisites for the effect to emerge.

Material perception of a kinetic illusory object with amplitude and frequency changes in oscillated inducer motion
Vision Research, 2015Co-Authors: Tomohiro Masuda, Kazuya Matsubara, Ken Utsumi, Yuji WadaAbstract:Abstract The magnitude of the phase difference between inducers’ oscillation of a kinetic illusory surface influences Visual Material impressions (Masuda et al., 2013). For example, impressions of bending or waving motions on a surface tend to occur at a 30- or 90-deg. phase difference, respectively. Here, we elucidate whether amplitude and frequency changes in an inducer’s oscillation influence the Visual impressions of an illusory surface’s hardness, elasticity, and viscosity. Nine participants were asked to use an analog scale to judge their Visual impressions relative to a standard pattern with no damping and no frequency change for each phase difference. Results revealed that hardness ratings were greater when amplitude decayed with time only in the 30-deg. phase difference. Elasticity ratings were greater when the frequency of oscillation had a large increase in the 90-deg. phase difference. In the 30-deg. phase difference, similar tendencies were only observed with no damping and ample damping. Viscosity ratings were greater when the frequency of oscillation decreased in both phase differences and when the amplitude decayed with time in the 30-deg. phase difference. These findings suggest that amplitude and frequency changes in an inducer’s oscillation are significant factors for Material perception derived from motion.

on teaching bedside diagnostic and therapeutic procedures to medical students an annotated bibliography of audioVisual Materials
Journal of General Internal Medicine, 1994Co-Authors: Archie A MackinneyAbstract:Objective: The teaching of procedures that involve risk of pain or morbidity deserves special care. The author set out to develop a teaching program for medical students to ensure quality control of bedside diagnostic and therapeutic procedures. Design: A bibliography of available videotapes and related audioVisual teaching Materials on 15 common bedside procedures was assembled following requests for Materials from all U.S. medical schools. AudioVisual Materials from nine institutions were reviewed. Setting: Medical schools and teaching institutions. Participants: Medical schools and libraries. Main results: Seventy-three percent (24/33) of responding schools had no Visual Material on the procedures. There was ten times more Material on physical diagnosis than on bedside procedures. About 20 videotapes were reviewed in an annotated bibliography. Some videos contained valuable insights on how to make good teaching Materials. A set of criteria for quality videotapes is listed. Conclusions: Considerable work needs to be done to develop audioVisual Materials and curricula for teaching bedside procedures. Videotape is a valuable medium for introducing procedures and ensuring uniformity of technique. After reviewing all available videotapes, the author decided that videotapes should be the initial part of a multidimensional program for teaching procedures.
