Onze blogger Franziska Wolf is afgestudeerd!

Op 1 december 2017 heeft Franziska haar diploma aan de Universiteit van Maastricht in ontvangst genomen. Daarmee heeft zij haar Master Rechtspsychologie Cum Laude afgerond. Wij feliciteren haar hiermee van harte en wensen haar veel succes bij de volgende stap in haar carrière.

Intussen verrast Fran ons met regelmaat op blogs waarin zij onderwerpen bespreekt op het gebied van “investigatieve interviewing”. Dat is niet zo verrassend als je weet waar haar interesse naar uitgaat. Haarmasterscriptie betrof dan ook onderzoek naar het effect van de  Do Not Guess Instruction zoals deze wordt gebruikt bij met name het cognitief interview.

Hieronder vindt u de conclusie van haar onderzoek in het kader van haar masterscriptie.

To summarize, the current study seeking to investigate the justifiability of including a do not guess warning in the instructions for witness testimonies, three main hypotheses were tested. The first pertained to the expected decreasing quantity and increasing quality of testimonies under increasingly elaborate DNG instructions. This was not confirmed by statistical analyses, while some trends in the data suggested that the most favorable outcome measures are obtained with a simple DNG warning. Second, it was hypothesized that memory distrust would be related to the measures of testimony quantity and quality, in that individuals with low memory trust would report less details with lower accuracy, and those with high memory trust would report more and with increased accuracy. The data did not lend support for this hypothesis – no relations were found between the described measures. Thirdly, it was expected that confidence ratings about own testimony characteristics would be highest for the explicit DNG condition, which was partially supported by the current results. The explicit DNG group showed significantly more confidence in the completeness of their reports than the control condition. This observation was not evident in actual quantity and accuracy rates, however. Based on these findings, and keeping in mind the limitations of the current study, the suggestion is put forth to seek further insight into the DNG instruction before including it in standard interviewing manuals of the CI kind. The data does not present reason to believe that omitting this instruction until it is satisfactorily supported by research would have any detrimental effect. To the contrary – the current findings seem to suggest that the DNG instruction does little to alter the high performance of mock witnesses as per status quo without such a warning. We make an appeal to the investigative interviewing research community to complete the evidence-base for all components of the CI, in order to continue the dissemination of interviewing tools that are fully justifiable and defensible.
