No full textNew perspective in assessing deception: The evolution of the truth machine
No full textIn recent years a growing interest has arisen in the development of tools for the detection of deception. Since William M. Marston's first publication (1917) on the use of the polygraph as a lie detector, the application of this tool, commonly known as the truth machine, has evolved. Modern technologies are now trying to push the issue further, investigating brain activity during deception using functional Magnetic Resonance Imaging (fMRI). The aim of this paper is to summarise the evolution of research from the original use of the polygraph to the use of new technologies in detecting deception, in order to provide an overview of the recent developments on the use of measurements of deception, and promote new research in this highly important domain of applied cognitive psychology
Interrogative suggestibility: Was it just compliance or a genuine false memory?
No full textPurpose. Interrogative suggestibility, as measured by the Gudjonsson Suggestibility Scales (GSS), is an independent form of suggestibility arising in the forensic/legal context. So far, an unresolved issue that may have different implications when measuring suggestibility is to what extent the scales measure internalization of suggested materials or just compliance with the interrogator. Methods. Internalization of suggested materials and compliance were here measured using a source identification task. In Experiment 1, participants were administered the GSS2 and immediately afterwards asked to perform the source identification task on the items presented in the scale. In Experiment 2, half of the participants were administered the source identification task immediately and half after a 24-hr delay. Results. In both experiments a higher proportion of compliant responses were found. Participants internalized more suggested information after questioning (Yield 1) and made more compliant responses after negative feedback (Shift). In Experiment 2, participants in the delayed condition internalized less material than those in the immediate condition. Conclusions: Different processes appear to underlie Yield 1 and Shift scores in the GSS2. The former may include both internalization of suggested materials and compliance, while the second appears to be mostly due to compliance with the interrogator. When administering the GSS2 in a forensic/legal context as vulnerability predictor for making false confessions, or proneness to develop false memories through the internalization of suggested material, including a source identification task may provide additional information on the type of coping style and memory characteristics of the examinee.Purpose.

Long-Term Memory Effects of Eye Closure on Children Eyewitness Testimonies
No full textPrevious studies conducted on adults and children found that closing the eyes while recalling an event increased memory accuracy for both free and cued recall. One possible explanation to this phenomenon is that eye closure increases the amount of cognitive resources devoted to the task reducing external stimulation, but it is still not clear whether the beneficial effect is only due to a better focus on the task or to a better encoding of the material leading to an advantage over time. In this study, we evaluated the effect of eye closure instruction on children memory accuracy for a short clip in an immediate and delayed recall. We observed that asking participants to close their eyes while performing a memory task helped them to remember more details and that this effect persisted after a time delay. © 2012 John Wiley & Sons, Ltd
