    Witnesses' failure to detect covert manipulations in their written statements

    Law enforcement agencies and legal professionals often have to rely on witness statements. Undetected errors in witnesses' statements, however, could impede the accurate reconstruction of a crime and lead to the incrimination of innocent suspects. Here, we examined whether witnesses can detect manipulations in their written statements. We expect that writing a statement could provide a good means for discrimination between what is truly recalled and what is an error. This is because writing allows to monitor and control the previously produced information. In 3 experiments, participants watched a mock crime film and subsequently provided a written statement of what they had witnessed. Following a delay of several minutes (Experiment 1), 48hr (Experiment 2), or 1month (Experiment 3), participants were exposed to and interviewed about their testimony. Unknown to them, they were confronted with statements, which included 4 secretly manipulated details. Participants' missed a substantial number of manipulations in their written statements. Importantly, the detection rates varied as a function of delay (Experiments 1 and 2: 74-89%; Experiment 3: 36%-52%). Detection rates also varied as a function of the type of details that were manipulated. Our findings indicate that writing a statement comes with limited benefits in witnesses' ability to detect errors in their statements

    Allegiance Bias in Statement Reliability Evaluations Is Not Eliminated by Falsification Instructions

    Are expert witnesses biased by the side (defense vs. prosecution) that hires them? We examined this issue by having students act as expert witnesses in evaluating interviews in a child sexual abuse case (Experiment 1, N = 143) and tested the value of an instruction to counteract such allegiance effects. The intervention concerned an instruction to consider arguments both for and against the given hypothesis (i.e., two-sided instructions; Experiment 2, N = 139). In Experiment 3 (N = 123), we additionally provided participants with three different scenarios. Participants received a case file regarding a case of alleged sexual abuse. With the file, participants received an appointment letter emphasizing elements of the file that questioned (defense) or supported (prosecution) the veracity of the accusation. Participants displayed allegiance bias (Experiments 1–3), but two-sided instructions were not successful in eliminating allegiance bias (Experiments 2 and 3). The findings underscore the importance of legal safeguards in expert witness work

    Zuflucht, Anerkennung und "heimisch werden" - Herausforderungen aktueller (Bildungs-) Politik in didaktischer, kinder- und jugendliterarischer und pädagogischer Perspektive

    Alles in allem steht die deutsche Gesellschaft heute sowie in den nächsten Jahren vor der großen Herausforderung viele geflüchtete Menschen in unsere Gesellschaft zu integrieren. Die Aufnahme der Geflüchteten war dazu nur ein erster, wichtiger Schritt. Dazu werden sowohl Konzepte im Rahmen der Bildung als auch in der Berufswelt benötigt – es erfordert jedoch auch, entsprechende Vorurteile abzubauen, offen zu sein für diese Menschen und neue Erfahrungen, sodass wir hoffen, dass Angela Merkel mit dem Satz „Wir schaffen das!“ Recht behalten wird

    Register: Language Users’ Knowledge of Situational-Functional Variation

    Get PDF
    The Collaborative Research Center 1412 “Register: Language Users’ Knowledge of Situational-Functional Variation” (CRC 1412) investigates the role of register in language, focusing in particular on what constitutes a language user’s register knowledge and which situational-functional factors determine a user’s choices. The following paper is an extract from the frame text of the proposal for the CRC 1412, which was submitted to the Deutsche Forschungsgemeinschaft in 2019, followed by a successful onsite evaluation that took place in 2019. The CRC 1412 then started its work on January 1, 2020. The theoretical part of the frame text gives an extensive overview of the theoretical and empirical perspectives on register knowledge from the viewpoint of 2019. Due to the high collaborative effort of all PIs involved, the frame text is unique in its scope on register research, encompassing register-relevant aspects from variationist approaches, psycholinguistics, grammatical theory, acquisition theory, historical linguistics, phonology, phonetics, typology, corpus linguistics, and computational linguistics, as well as qualitative and quantitative modeling. Although our positions and hypotheses since its submission have developed further, the frame text is still a vital resource as a compilation of state-of-the-art register research and a documentation of the start of the CRC 1412. The theoretical part without administrative components therefore presents an ideal starter publication to kick off the CRC’s publication series REALIS.

    Quantifier scope in sentence prosody? : A view from production

    Get PDF
    Logical scope interpretation and sentence prosody exhibit intricate, yet scarcely studied interrelations across a variety of languages and constructions. Despite these observable interrelations, it is not clear whether quantifier scope by itself is able to directly affect prosodic form. Information structure is a key potential confounding factor, as it appears to richly interact both with scope interpretation and with prosodic form. To address this complication, the current study investigates, based on data from Hungarian, whether quantifier scope is expressed prosodically if information structure is kept in check. A production experiment is presented that investigates grammatically scope ambiguous doubly quantified sentences with varied focus structures, while lacking a syntactically marked topic or focus. In contrast to the information structural manipulation, which is manifest in the analysis of the acoustic data, the results reveal no prosodic effect of quantifier scope, nor the interaction of scope with information structure. This finding casts doubt on the notion that logical scope can receive direct prosodic expression, and it indirectly corroborates the restrictive view instead that scope interpretation is encoded in prosody only in cases in which it is a free rider on information structure

    Cross-linguistic patterns in the acquisition of quantifiers.

    Learners of most languages are faced with the task of acquiring words to talk about number and quantity. Much is known about the order of acquisition of number words as well as the cognitive and perceptual systems and cultural practices that shape it. Substantially less is known about the acquisition of quantifiers. Here, we consider the extent to which systems and practices that support number word acquisition can be applied to quantifier acquisition and conclude that the two domains are largely distinct in this respect. Consequently, we hypothesize that the acquisition of quantifiers is constrained by a set of factors related to each quantifier's specific meaning. We investigate competence with the expressions for "all," "none," "some," "some…not," and "most" in 31 languages, representing 11 language types, by testing 768 5-y-old children and 536 adults. We found a cross-linguistically similar order of acquisition of quantifiers, explicable in terms of four factors relating to their meaning and use. In addition, exploratory analyses reveal that language- and learner-specific factors, such as negative concord and gender, are significant predictors of variation.This is the author accepted manuscript.

    A crosslinguistic study of symmetrical judgments

    Get PDF
    A longstanding puzzle in developmental linguistics is why children are more permissive than adults in assigning distributive interpretations to sentences with the universal quantifiers each, every, and all under certain experimental conditions. One well-known controversial issue in this area is children’s symmetrical judgments of universally quantified sentences. Symmetrical judgments are elicited when a child is asked to judge if a sentence including a universal quantifier describes a visual context depicting an incomplete distributive relation. The following three judgment types have been included in the set of symmetrical judgment types in the literature (examples from Kang, 2001).peer-reviewe

    Measurement of the t(t)over-bar production cross section in pp collisions at root s=7 TeV in dilepton final states containing a tau

    The top quark pair production cross section is measured in dilepton events with one electron or muon, and one hadronically decaying tau lepton from the decay t (t) over bar -> (l nu(l))((sic)(h)nu((sic)))b (b) over bar, (l = e, mu). The data sample corresponds to an integrated luminosity of 2.0 fb(-1) for the electron channel and 2.2 fb(-1) for the muon channel, collected by the CMS detector at the LHC. This is the first measurement of the t (t) over bar cross section explicitly including tau leptons in proton- proton collisions at root s = 7 TeV. The measured value sigma(t (t) over bar) = 143 +/- 14(stat) +/- 22(syst) +/- 3(lumi) pb is consistent with the standard model predictions
