Contextual Bias in Verbal Credibility Assessment: Criteria‐Based Content Analysis,Reality Monitoring and Scientific Content Analysis

Verbal credibility assessment encompasses several methods used to evaluate the credibility of statements by examining their content. In two experiments, we tested to what extent these methods are sensitive to contextual bias. Four statements were presented, although their context was manipulated by confronting raters with extra‐domain information that either enhanced or diminished the credibility of the statements. In Experiment 1, 32 police officers analysed the statements using scientific content analysis. In Experiment 2, 128 undergraduates analysed the statements using criteria derived from criteria‐based content analysis, reality monitoring or scientific content analysis. Results showed that all three methods were equally vulnerable to contextual bias. Copyright © 2013 John Wiley & Sons, Ltd.     

The utility of screen for child anxiety related emotional disorders (scared) as a tool for identifying children at high risk for prevalent anxiety disorders

Abstract

The current study examined the utility of the Screen for Child Anxiety Related Emotional Disorders (SCARED) as a screening tool for the identification of children at high risk for prevalent childhood anxiety disorders. The child version of the Structured Clinical Interview for DSM (KSCID) was used as the diagnostic standard. It was investigated whether SCARED scores are indicative for the presence of generalized anxiety disorder, separation anxiety disorder, and social phobia. Five-hundred-and-thirty-seven children aged 7–14 years completed the SCARED. From this sample, 82 children were selected on the basis of their SCARED scores. A subgroup of these children scored relatively high on the generalized anxiety disorder, separation anxiety disorder, and/or social phobia scale(s) of the SCARED. A comparison group of children scored relatively low on these SCARED scales. Both groups of children then received the semi-structured interview to assess to what extent they fulfilled the DSM-IV criteria for the relevant anxiety disorders. Results provided some support for the predictive validity of the SCARED generalized anxiety disorder and separation anxiety disorder subscales. The implications of these findings for the detection of anxiety disorders in normal children are briefly discussed.     

Go/NoGo Performance in Boys with Tourette Syndrome

This study compared performance and performance monitoring in 19 boys with Tourette syndrome (TS) (12.64 years, ± 2.05) and 19 age-matched controls (13.16 years, ± 2.29) using a Go/NoGo task. The results indicated similar performance accuracy in the TS group and the control group. TS participants showed slower correct responses than the control group, whereas error response times were not different between the groups. The results are discussed with reference to inhibitory adaptive effects that may be employed by TS participants to maintain high accuracy at the cost of overall slower performance. These effects may be suspended prior to errors.     

“Yes,I Have Sometimes Stolen Bikes”: Blindness for Norm‐Violating Behaviors and Implications for Suspect Interrogations

Across two experiments, we studied a phenomenon akin to choice blindness in the context of participants' accounts of their own history of norm‐violating behaviors. In Experiment 1, N = 67 participants filled in an 18‐item questionnaire about their history of norm‐violating behaviors (QHNVB). Subsequently, they were questioned about four of their answers, two of which had covertly been manipulated by the experimenter. Of the 134 manipulations, 20 (14.9%) remained undetected concurrently and 13 were accepted in retrospect (9.7%). In Experiment 2 (N = 37), we inserted a one‐week interval between questionnaire and interview. Twenty‐seven (36.5%) of the 74 manipulations remained undetected concurrently and three were accepted in retrospect (8.1%). Data obtained in a four‐week follow‐up indicated that our manipulations may have long‐term effects on participants' perception of their own history of norm‐violating behaviors. Implications for the occurrence of false confessions during the course of an interrogation are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

The hyphen as a segmentation cue in triconstituent compound processing: it's getting better all the time

Bertram, R., Kuperman, V., Baayen, R. H. & Hyönä, J. (2011). The hyphen as a segmentation cue in triconstituent compound processing: It’s getting better all the time. Scandinavian Journal of Psychology 52, 530–544. Inserting a hyphen in Dutch and Finnish compounds is most often illegal given spelling conventions. However, the current two eye movement experiments on triconstituent Dutch compounds like voetbalbond“footballassociation” (Experiment 1) and triconstituent Finnish compounds like lentokenttätaksi“airporttaxi” (Experiment 2) show that inserting a hyphen at constituent boundaries does not have to be detrimental to compound processing. In fact, when hyphens were inserted at the major constituent boundary (voetbal‐bond“football‐association”; lentokenttä‐taksi“airport‐taxi”), processing of the first part (voetbal“football”; lentokenttä“airport”) turns out to be faster when it is followed by a hyphen than when it is legally concatenated. Inserting a hyphen caused a delay in later eye movement measures, which is probably due to the illegality of inserting hyphens in normally concatenated compounds. However, in both Dutch and Finnish we found a learning effect in the course of the experiment, such that by the end of the experiments hyphenated compounds are read faster than in the beginning of the experiment. By the end of the experiment, compounds with a hyphen at the major constituent boundary were actually processed equally fast as (Dutch) or even faster than (Finnish) their concatenated counterparts. In contrast, hyphenation at the minor constituent boundary (voet‐balbond“foot‐ballassociation”; lento‐kenttätaksi“air‐porttaxi”) was detrimental to compound processing speed throughout the experiment. The results imply that the hyphen may be an efficient segmentation cue and that spelling illegalities can be overcome easily, as long as they make sense.     

Implicit and explicit emotional behavior and mindfulness

The objective of this study was to examine whether the “step back and watch” attitude of mindfulness manifests in less emotional behavior. We hypothesized that the “acceptance” facet of mindfulness, but not the “presence” facet, is negatively associated with the magnitude of emotional behavior in four tests, i.e., (1) rating of words, (2) rating of aversive and neutral pictures, and (3) evaluative conditioning (EC). Additionally, we hypothesized that (4) the acceptance facet is associated with increased reaction time (RT) in an emotional Stroop test, and that the presence facet is associated with decreased RT and lower error rate. The sample consisted of N = 247 non-clinical adults and was tested in a cross-sectional study. The results provide partial evidence that the acceptance facet of mindfulness may be associated with less aversive reactions towards aversive stimuli. Future studies should substantiate these findings but also determine their clinical relevance.     

Stressbew?ltigungsintervention am Arbeitsplatz

Background

Occupational stress is considered a major risk factor for a wide range of health outcomes. To examine long-term effects on perceived stress reactivity a randomized controlled trial [1?year after stress management intervention (SMI)] was implemented in a metal working plant.

Method

A total of 174 participants were randomly assigned to an intervention (IG) or a waiting control group (CG) and underwent a group-based program over 2 days, followed by 2-3?h booster sessions. The primary endpoint was perceived stress reactivity (Stress Reactivity Scale, SRS), while secondary endpoints were anxiety and depression (Hospital Anxiety and Depression Scale, HADS), salivary cortisol and alpha-amylase.

Results

SRS scores decreased in both groups. A two factor ANOVA proved greater reduction in the IG. For SRS, the effect size (Cohen??s d) after 1?year was d=0.416 in the IG and d=0.166 in the CG. Alpha-amylase as a measure of sympathetic nervous system activation decreased more strongly in the IG. Reduction of depression and anxiety was higher in the IG but did not reach statistical significance.

Conclusion

The conducted SMI is effective over a longer period in reducing perceived stress reactivity and sympathetic activation.
