Psychophysiological and vocal measures in the detection of guilty knowledge.

2004

The Guilty Knowledge Test (GKT) and its variant, the Guilty Actions Test (GAT), are both psychophysiological questioning techniques aiming to detect guilty knowledge of suspects or witnesses in criminal and forensic cases. Using a GAT, this study examined the validity of various physiological and vocal measures for the identification of guilty and innocent participants in a mock crime paradigm. Electrodermal, respiratory, and cardiovascular measures successfully differentiated between the two groups. A logistic regression model based on these variables achieved hit rates of above 90%. In contrast to these results, the vocal measures provided by the computerized voice stress analysis system …

Electrodermal and phasic heart rate responses in the Guilty Actions Test: comparing guilty examinees to informed and uninformed innocents.

2007

The present mock-crime study concentrated on the validity of the Guilty Actions Test (GAT) and the role of the orienting response (OR) for differential autonomic responding. N=105 female subjects were assigned to one of three groups: a guilty group, members of which committed a mock-theft; an innocent-aware group, members of which witnessed the theft; and an innocent-unaware group. A GAT consisting of ten question sets was administered while measuring electrodermal and heart rate (HR) responses. For informed participants (guilty and innocent-aware), relevant items were accompanied by larger skin conductance responses and heart rate decelerations whereas irrelevant items elicited HR accelera…

Life success of males on nonoffender, adolescence-limited, persistent, and adult-onset antisocial pathways: follow-up from age 8 to 42

2009

A random sample of 196 males, drawn from the Jyväskylä Longitudinal Study of Personality and Social Development, was divided into four groups of offenders using information from government registers of convictions between ages 21 and 47, from local police registers searched at age 21, from a Self-Report Delinquency Scale administered at age 36, from a Life History Calendar for ages 15-42, and from personal interviews at ages 27, 36, and 42. The groups were: persistent offenders (offences before and after age 21; 29% of the men); adolescence-limited offenders (offences before age 21; 27%); adult-onset offenders (offences after age 21; 16%); and nonoffenders (28%). The profile of the persiste…
