Abstract
The Guilty Knowledge Test (GKT) is a psychophysiological questioning technique that can be used as part of a polygraph examination which purports to assess whether suspects conceal “guilty knowledge” by measuring their physiological responses while responding to a series of multiple choice questions. The present study sets out to consider a number of key issues in relation to the GKT paradigm. Specifically, the following questions were considered: Does response mode matter? Does motivation influence outcome? Are combined physiological measures better than single ones? Does gender have an effect on physiological responsivity during a polygraph examination? Results demonstrated real variations between the physiological measures used. Gender differences were also observed in polygraph response patterns. These findings are discussed in relation to the validity of the Guilty Knowledge Test.

Abstract
Purpose
The purpose of this paper is to review the status of biosignal measures of female sexual arousal with a view to examining the feasibility of such procedures in a forensic context. Although adult women represent the minority of sexual offenders, female perpetrated sexual abuse has been gaining increasing attention in the forensic psychological literature as criminal justice is confronted with female offending populations to a greater extent than previously recognised.
Design/methodology/approach
Psychological assessments of sex offenders have tended to be over-dependent on the use of self-report measures (i.e. an individual's appraisal and report of their emotional state of sexual arousal). There is a dearth of empirical knowledge concerning the psychophysiological assessment of female sexual interest in general and especially so for female sex offenders. Physiological measures are those that rely on directly observable physiological responses of the individual in order to identify patterns of sexual interest or arousal.
Findings
Because deviant sexual interest (in children or the use of violence) as assessed by penile plethysmography, has been established as one of the strongest predictors of recidivism in male sex offenders (and as a viable alternative to self-report methodologies), an analogue measurement approach for female sex offenders is desirable. This paper considers: first, theoretical problems (e.g. what does female physiological arousal mean in terms of sexual arousal/desire?; second, technical measurement problems (e.g. reactivity of the measure in within subject designs); and third, procedural/ethical problems (e.g. invasiveness of the application).
Originality/value
While a number of physiological assessment devices are considered in this paper, the paper discusses the labial photoplethysmograph as a promising method for female sexual offender populations.

Abstract
Purpose
LifeMatters is a cognitive behavioural coaching programme that provides tools and techniques for developing and applying five areas of life skill competency: taking care of the body, feeling positive, thinking wisely, acting wisely, and taking care of the spirit. The purpose of paper is to evaluate the viability of the LifeMatters programme with a cohort of secondary school students (12-15 years) in Ireland.
Design/methodology/approach
Open-ended feedback obtained from 196 participants who completed an open-ended questionnaire. These responses were subjected to a thematic analysis. Subsequent quantitative analysis of the resulting categorical data were carried out using correspondence analysis.
Findings
Categorical analysis produced statistically significant sex and age differences showing that males and females differed in their experience of the programme. Girls benefited more from a focus upon stress and self-confidence whereas boys benefited more from a focus on relationship building.
Originality/value
This study demonstrates the viability of the LifeMatters programme for secondary school students as an aid to develop life skills. It highlights the different needs of boys and girls in this area.
