Roeterseilandcampus - Gebouw C, Straat: Nieuwe Achtergracht 129-B, Ruimte: GS.11. Vanwege beperkte zaalcapaciteit is deelname op basis van wie het eerst komt, het eerst maalt. Leraren moeten zich hieraan houden.

Bogaard et al. (2014) suggested that contextual information biases how participants evaluate the credibility of victim statements in CBCA-based (Criteria-Based Content Analysis) assessments. Later studies found no contextual bias in the CBCA, but in final credibility judgments. In this direct replication (n = 105), participants scored four statements (kidnapping, murder, sexual abuse, rape) on CBCA criteria and final credibility. The statements were preceded by either credibility-enhancing (e.g., prior abuse allegations) or credibility-reducing (e.g., motive to lie) information. As predicted, statements paired with credibility-enhancing information received higher CBCA (d = 0.33; BF+0 = 39.38) and final credibility scores (d = 0.88; BF+0 = 1.356 × 1012). Exploratory analyses suggest the effect is strongest in the sexual abuse statement, with Criteria 1 (Logical Structure), 3 (Amount of Detail), and 19 (Crime Characteristics) most affected. Future research should examine which types of contextual information are strong enough to elicit bias in CBCA scores.
