Rapport-building: Chat versus in-person witness interviews

Tactics recommended for rapport-building consist of verbal (e.g., finding common ground or shared experiences) and non-verbal (e.g., affirmations, displaying empathy) behaviours. Most of the research on rapport, however, has examined it in in-person contexts, where both verbal and non-verbal behaviours are present. In this study, we were interested in the effectiveness of rapport-building when conducting online witness interviews via chat, which de-emphasises the use non-verbal rapport behaviours, compared to traditional in-person interviews. Participants (N = 131) experienced a virtual reality (VR) scenario depicting a mock crime and were interviewed either in person or online via the chat function in Skype. Participants perceived rapport more positively when interviewed in person for three measures: attentiveness, trust and respect and expertise. Two other measures, cultural similarity and connected flow, were not perceived differently across interview medium. Participants interviewed online via chat disclosed similar amounts of crime-related information and were just as accurate as participants interviewed in person. We found that in-person interviews yielded better rapport ratings than interviews via chat but were equally productive in terms of the quality of information obtained, as measured by crime-related details and accuracy. If witnesses are to be interviewed via chat, investigators must carefully consider how to compensate for the lack of those non-verbal rapport tactics that influence witnesses' perceptions of attentiveness, trust/respect and investigator's expertise.     

General education,cultural diversity,and identity

The issue of this paper is cultural plurality as a problem for public, general education and for (personal) identity. In order to examine this question, one needs to be clear about the meaning of the concepts of general education, on the one hand, and cultural diversity on the other. In the first section, we will fix the meaning of these concepts. A conceptual distinction between cultural diversity and cultural pluralism will be introduced. In the second section, it will be argued that open pluralism can only be maintained if there is a basic common culture apart from the cultural diversity that pluralism affirms. Therefore, there is yet an indispensable role for general education in an open, pluralistic society. In the third section we will look at two metaphors that give an opposite significance to the relation between identity and diversity: the conversational metaphor and the food metaphor mishmash. The final section expands on the conversational metaphor by way of an exposition of Ricoeur's hermeneutics of the self. It supplies us with a promising concept of identity that is not in complete opposition to diversity.     

Bernstein's theory of movement behavior: historical development and contemporary relevance

In present-day movement science, N. A. Bernstein's formulation of the problems of motor control is often taken as the starting point. The reliance on Bernstein has not brought agreement among his followers, however. In this article, the authors pose the following question: Does the disagreement arise from the structure of his work itself or from incomplete exploitation of his thinking? By using, inter alia, Bernstein's 24 English and German articles, the authors present an analysis of the development of Bernstein's theory of movement behavior, against the backdrop of the scientific progress in the Soviet Union in Bernstein's time and the clashes between Soviet politics and science. Bernstein addressed in his early articles the measurement and biomechanical analysis of movements. His experimental data soon indicated the need for a new understanding of the organization of movements, which he formulated in terms of coordination. Because of political problems, his work was interrupted; but after being "rehabilitated" and again allowed to work, Bernstein aimed to explain how animals find and optimize the solutions to motor problems. The structure of the theory that ensued was comprehensive exactly by virtue of his repeatedly shifting focus between the different aspects of the organization of movement: More important than the answers he gave were the questions he asked. Moreover, the way he approached those questions may help scientists solve pressing problems in present-day movement science.     

Analyzing psychopathology items: a case for nonparametric item response theory modeling

The authors discuss the applicability of nonparametric item response theory (IRT) models to the construction and psychometric analysis of personality and psychopathology scales, and they contrast these models with parametric IRT models. They describe the fit of nonparametric IRT to the Depression content scale of the Minnesota Multiphasic Personality Inventory--2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989). They also show how nonparametric IRT models can easily be applied and how misleading results from parametric IRT models can be avoided. They recommend the use of nonparametric IRT modeling prior to using parametric logistic models when investigating personality data.     

Diagnosing item score patterns on a test using item response theory-based person-fit statistics

Person-fit statistics have been proposed to investigate the fit of an item score pattern to an item response theory (IRT) model. The author investigated how these statistics can be used to detect different types of misfit. Intelligence test data were analyzed using person-fit statistics in the context of the G. Rasch (1960) model and R. J. Mokken's (1971, 1997) IRT models. The effect of the choice of an IRT model to detect misfitting item score patterns and the usefulness of person-fit statisticsfor diagnosis of misfit are discussed. Results showed that different types of person-fit statistics can be used to detect different kinds of person misfit. Parametric person-fit statistics had more power than nonparametric person-fit statistics.     

Building syntactic structures in speaking: a bilingual exploration

In a series of three experiments we investigated syntactic priming using a sentence recall task. Participants read and memorized a target sentence for later recall. After reading a prime sentence and engaging in a distraction task, they were asked to produce the target sentence aloud. Earlier investigations have shown that this task is sensitive to a syntactic priming effect. That is, the syntactic form of the prime sentence sometimes influences the syntactic form of the recalled target. In this paper we report on a variation on this task, using Spanish-English bilingual participants. In the first two experiments we replicated the prepositional phrase priming effect using English target sentences and Spanish prime sentences. In the final experiment we investigated two additional syntactic forms, using Spanish target sentences and English prime sentences. Implications for models of syntax generation and bilingual speech production are discussed.     

Building Syntactic Structure in Speaking

We investigated how people produce simple and complex phrases in speaking using a newly developed immediate recall task. People read and tried to memorize a target sentence, then read a prime sentence, then did a distractor task involving the prime sentence. Despite the delay and activity between memory and recall, people could still recall the target sentence although the syntactic form of the recalled sentence was influenced by the syntactic form of the prime sentence. This result replicates the syntactic priming effect found with other experimental paradigms. Using this task, we tested how people used abstract syntactic plans to produce simple and complex noun phrases. We found syntactic priming both when targets and prime sentences matched in complexity and when they did not match, suggesting that simple and complex noun phrases are built by the same syntactic routines during speech production.     

The use of fruiting synchrony by foraging mangabey monkeys: a ‘simple tool’ to find fruit

Previous research has shown that a considerable number of primates can remember the location and fruiting state of individual trees in their home range. This enables them to relocate fruit or predict whether previously encountered fruit has ripened. Recent studies, however, suggest that the ability of primates to cognitively map fruit-bearing trees is limited. In this study, we investigated an alternative and arguably simpler, more efficient strategy, the use of synchrony, a botanical characteristic of a large number of fruit species. Synchronous fruiting would allow the prediction of the fruiting state of a large number of trees without having to first check the trees. We studied whether rainforest primates, grey-cheeked mangabeys in the Kibale National Park, Uganda, used synchrony in fruit emergence to find fruit. We analysed the movements of adult males towards Uvariopsis congensis food trees, a strongly synchronous fruiting species with different local patterns of synchrony. Monkeys approached within crown distance, entered and inspected significantly more Uvariopsis trees when the percentage of trees with ripe fruit was high compared to when it was low. Since the effect was also found for empty trees, the monkeys likely followed a synchrony-based inspection strategy. We found no indication that the monkeys generalised this strategy to all Uvariopsis trees within their home range. Instead, they attended to fruiting peaks in local areas within the home range and adjusted their inspective behaviour accordingly revealing that non-human primates use botanical knowledge in a flexible way.
