Abstract: This paper demonstrates how biometric features can be extracted from people in child sexual abuse material (CSAM) and examined using social network analysis to reveal important patterns across seized media files. Using an automated software system previously developed by the research team (the Biometric Analyser and Network Extractor), we extract, match and plot multiple biometric attributes (face and voice) from a database of CSAM videos compiled by law enforcement. We apply a series of network measures to illustrate how the biometric match data can be used to rapidly pinpoint key media files associated with an investigation, without the need for an investigator to manually review and catalogue all files. Future directions for this research are also discussed.

Abstract: According to expectancy violations theory, displays of behavior considered “unusual” during an interaction will trigger scrutiny of an in idual. Such scrutiny may be detrimental in forensic contexts, where deception detection is emphasized. Autistic in iduals, in particular, may be scrutinized unfavorably given unusual nonverbal behavior associated with the condition. Across two experiments using between-subjects’ designs, participants (overall N = 3,342) watched a scripted police-suspect interrogation, randomized to view the suspect display autism-related behaviors or none of those behaviors. Autistic behavior biased evaluations of deception and guilt as a function of violating in idual behavioral expectations, regardless of whether decisive or ambiguous evidence framed the suspect as guilty or innocent. Promisingly, however, providing an autism information card attenuated such evaluations. Our research extends expectancy violations theory, advances understanding of determinants of forensic judgments, highlights important applied implications for nonverbal behavior displays in the justice system and recommends methods to protect against bias.

Abstract: Research has shown that psychosocial and behavioral factors are associated with engagement in a range of deviant behaviors across offline settings. To date, however, very little research has explored the impact of these factors in online contexts. This article addresses this gap by examining the psychosocial and behavioral factors associated with common types of adolescent cyberdeviance. This is accomplished through an empirical study of 327 adolescents enrolled in a high school located in a large Australian city. The study assesses various aspects of psychosocial and behavioral functioning using the Strengths and Difficulties Questionnaire (total difficulties, internalizing problems, externalizing problems, prosocial behavior), as well as numerous types of cyberdeviance relevant to young people, including cyberfraud, cyberhate, cyberviolence, sexting, digital piracy, hacking, and cyberbullying. A series of multivariate logistic regression analyses were conducted to demonstrate the association between psychosocial and behavioral difficulties and various types of cyberdeviance, independent of gender, school grade, socioeconomic status, and engagement in offline delinquency. Results indicate that total difficulties, internalizing problems, and externalizing problems were significantly associated with greater likelihood of engagement in most types of cyberdeviance examined in this study, whereas prosocial behavior was associated with a lower likelihood of engagement in digital piracy only. A discussion of the findings highlights the importance of understanding these factors in a digital context, as well as demonstrating the need to account for them when designing targeted interventions.

Abstract: Verbal intelligence—which relates to memory performance, abstract reasoning, and g—is often important to account for within psychological research. However, the time demands and financial costs associated with researcher-administered testing using valid measures of intelligence limit researchers’ ability to include such measures within their research. To address this issue, we examined the convergent validity of two tests of verbal intelligence that could be self-administered online with the well-validated Wechsler Abbreviated Scale of Intelligence–Second Edition (WASI-II). An undergraduate s le of participants (N = 104) completed the Self-Administered Verbal IQ Test (SA-VIQT), with a subsection (n = 64) completing the Self-Administered Full Scale IQ Test (SA-FSIQT), both made available online by Open-Source Psychometrics Project. Additionally, all participants were administered the Verbal Comprehension Index (VCI) of WASI-II by a trained researcher, with a subsection administered the full WASI-II including the Perceptual Reasoning Index (PRI) (n = 72). Both online tests demonstrated convergent validity with the WASI-II. While the online tests may only deliver a crude indicator of verbal intelligence, they provide researchers the opportunity for statistical control or screening of participants across large s les in an efficient manner not possible when using researcher-administered testing methods.
