The Observer Video-Pro: New software for the collection, management, and presentation of time-structured data from videotapes and digital media files

The Observer Video-Pro is a system for collecting, managing, analyzing, and presenting observational data. It integrates The Observer software with time code and multimedia hardware components. It extends the functionality of a conventional real-time event recording program in various ways. Observational data can be collected, reviewed, and edited with synchronized display of the corresponding video images. For optimal visual feedback during coding, one can display the video image in a window on the computer screen. Video playback from either a VCR or a digital media file can be controlled by the computer, allowing software-controlled jog, shuttle, and search functions. Besides a wide range of VCRs, The Observer Video-Pro supports all major digital video file formats. The software allows the user to summarize research findings in numerical, graphical, or multimedia format. One can create a time-event plot for a quick glance at the temporal structure of the observed process, or run specific analysis procedures and generate reports with statistics. An Event Summary function is available for exploratory and qualitative analysis. Video material can be summarized in a Video Play List, which allows on-screen summary presentations or the creation of highlight compilations on tape, CD, or other media. Video images can be captured and saved as disk files, for use as illustrations in documents, slides for presentations, and so forth. In this paper we describe the design and operation of the system, illustrated with a case study from research on Repetitive Strain Injury (RSI).     

Priming and timing: a test of two perspectives

Supporting a ‘stage’ perspective of assimilation and contrast effects, and in contrast to an ‘extremity’ conceptualization, this study demonstrated that priming moderate person exemplars before the behaviour of an ambiguous target person had been encoded results in assimilation, whereas priming such exemplars after encoding results in a small contrast effect. © 1998 John Wiley & Sons, Ltd.     

Manual rotation training improves direction-estimations in a virtual environmental space

This study investigated in a virtual environment, whether the training of a small-scale ability, i.e., manual or mental rotation, has an influence on the large-scale ability to estimate a direction. Ninety-six participants completed a direction estimation task as a pretest and then received either a manual rotation or a mental rotation training or played a nonspatial computer game. After that they completed the direction estimation task once again. The results showed that the direction estimation error decreased from the pre- to posttest only for the manual rotation training group. For that, the small-scale spatial ability was at least partially related to the large-scale ability, which supports the Partial Dissociation Model.     

Applicants' Self‐presentational Behavior across Cultures: Less self‐presentation in Switzerland and Iceland than in the United States

Do US findings on applicants' self‐presentational behavior generalize to other countries? We argue that applicants in some countries are less motivated to present themselves favorably than applicants in others because countries vary in their unemployment rate (leading to differences in competition between job applicants) and their endorsement of modesty values, influencing their beliefs regarding self‐presentation. Using the randomized response technique, we obtained prevalence data on applicants' self‐presentational behavior from Iceland and Switzerland and compared them with previously published US results. The prevalence rates of self‐presentational behavior were fairly comparable in Iceland and Switzerland but significantly lower than in the United States. These results caution against using the same hiring strategy for all applicants from different cultures.     

Transforming the Self and Healing the Body Through the Use of Testimonies in a Divine Retreat Center, Kerala

In this article, we analyze the collective healing process that takes place on a weekly basis in the Divine Retreat Center (DRC) in Muringoor, Kerala. We argue that disease in the DRC is understood either as a psycho-somatic or as a spirito-somatic phenomenon. In contrast to other Charismatic communities, however, the body is the locus on which the medical effects of the healing become visible. The whole process is divided into several phases: First, there is a cleansing and disengagement procedure that aims to purify and liberate the participants through confession and counseling. Thereafter comes a climatic phase of personal emptying, transition and re-orientation during which the healing itself takes place. The procedure is finally completed with the person being spiritually "refilled" by the Holy Spirit. The dominant recurring element in the whole process is the continuous statement of healing "testimonies." As an integral part of the healing procedure, these statements are used to share personal experiences among the participants in the center. They are produced in a strict format in order to be spread far beyond through various media (TV, newspaper, Internet, etc.). They thereby constitute a speech genre that follows specific rules and patterns. Through shaping one's own biography in the frame of the testimonies, so we argue, the actual transformation of the self and therefore the miracle healing takes place.     

Community implementation of PMTO™: Impacts on referrals to specialist services and schools

Sigmarsdóttir, M. & Björnsdóttir, A. (2012). Community implementation of PMTO?: Impacts on referrals to specialist services and schools. Scandinavian Journal of Psychology 53, 506–511. In 2000, the city of Hafnarfjörður, Iceland, implemented Parent Management Training – Oregon Model (PMTO^?) to prevent and treat behavioral problems among children. This paper describes the implementation and findings regarding impacts in the community. As hypothesized, findings showed that the number of referrals to specialist services decreased in Hafnarfjörður following PMTO implementation and increased in two comparison communities not implementing the method. Within the Hafnarfjörður community, recorded instances of behavior problems reduced in elementary schools working in line with PMTO. The results presented are the first such findings in Iceland and suggest the kinds of systematic changes communities may experience following the implementation of an evidence‐based program.     

Conditions for rasch-dichotomizability of the unidimensional polytomous rasch model

Jansen and Roskam (1986) discussed the compatibility of the unidimensional polytomous Rasch model with dichotomization of the response continuum. They derived a rather strict condition in which dichotomization of multicategory data that fit the unidimensional polytomous Rasch model, results in dichotomous data which fit the dichotomous Research model with effectively the same subject parameter. In this paper a more general dichotomization condition is derived for the polytomous Rasch model, which appears less restrictive, but upholds that the intrinsic logic of the unidimensional polytomous Rasch model defies dichotomization in general. The robustness of dichotomous analysis investigated in a simulation study. It shows a close relation with the two-parameters (Birnbaum) model. Theoretical and methodological implications are discussed.The authors are indebted to H. Müller (personal communication, August 1986), for giving an example which pointed toward the core equation in this paper. The authors also acknowledge the critical comments of Th. Bezambinder and P. Wakker, and of Psychometrika's reviewers to an earlier version of this paper.     

Posture-based motion planning: applications to grasping.

This article describes a model of motion planning instantiated for grasping. According to the model, one of the most important aspects of motion planning is establishing a constraint hierarchy--a set of prioritized requirements defining the task to be performed. For grasping, constraints include avoiding collisions with to-be-grasped objects and minimizing movement-related effort. These and other constraints are combined with instance retrieval (recall of stored postures) and instance generation (generation of new postures and movements to them) to simulate flexible prehension. Dynamic deadline setting is used to regulate termination of instance generation, and performance of more than one movement at a time with a single effector is used to permit obstacle avoidance. Old and new data are accounted for with the model.     

Emotional,Cognitive, Behavioral,and Temperament Characteristics of High-Empathy Children

Recent research has suggested that individual differences in young children's capacity for empathy and altruism has heritable components and may be related to early temperament. These individual differences, like other human capacities such as intelligence, may be distributed normally. Thus, high-empathy children may exhibit cognitive, emotional, and behavioral precocity in empathic and altruistic responding, and begin expressing these capacities early in life. Twenty-seven 2- to 8-year-old (M = 53 months), primarily Euro-American high-empathy children (10 male) were identified by childcare center staff. Ethnographically oriented interviews of their mothers provided detailed accounts of the children's empathic and altruistic responding in everyday interactions at home and school. As a group, the children were described as emotionally positive, especially sociable individuals whose empathic and altruistic responses were highly spontaneous, occurred more frequently, and differed from peers in depth, intensity, and persistence. Parallels were drawn between these capacities and temperamental dispositions for self-regulation and emotional reactivity. Limitations of the methodology and directions of future research are discussed.
