Traits presumed to reflect dopaminergic reward and prefrontal executive systems functioning were assessed in 100 clients undergoing residential treatment for substance dependence and a community sample of 107 social drinkers. All participants completed self-report measures of impulsivity, alexithymia, frontal systems dysfunction, sensitivity to rewards and punishments, dispositional mindfulness...

BACKGROUND Two forms of impulsivity, rash impulsiveness and reward sensitivity, have been proposed to reflect aspects of frontal lobe functioning and promote substance use. The present study examined these two forms of impulsivity as well as frontal lobe symptoms in relation to risky drinking by university students. METHODS University undergraduates aged 18-26years completed the Alcohol Use D...

New evidence confirms that the auditory system encompasses temporal, parietal and frontal brain regions, some of which partly overlap with the visual system. But common assumptions about the functional homologies between sensory systems may be misleading.

Face recognition is a difficult problem and it becomes even more challenging for non-frontal view images (captured by a CCTV camera) commonly encountered in a forensic face recognition case. In a typical forensic case, the surveillance view test image (also called the trace) is captured by a CCTV camera and the reference set consists of frontal view mug shot image of the suspects. Comparison of...

Three-dimensional (3D) motion capture systems have been used to identify athletes in high risk of injury, but due their cost, lack portability and qualified technicians, an alternative is needed, such as two-dimensional (2D) systems. The purpose this study was examine the criterion-related validity three measures frontal plane knee alignment (Frontal projection angle [FPPA], knee-to-ankle separ...
