abstract = {Recent investigations have proposed that visual information may be sampled in a discrete manner, similarly to the snapshots of a camera, but this hypothesis remains controversial. Moreover, assuming a discrete sampling of information, the properties of this sampling-for instance, the frequency at which it operates, and how it synchronizes with the environment-still need to be clarified. We systematically modulated the signal-to-noise ratio of faces through time and examined how it impacted face identification performance. Altogether, our results support the hypothesis of discrete sampling. Furthermore, they suggest that this mechanism may operate at a rate of about 10-15. Hz and that it is synchronized with the onset of the stimulus. © 2013 Elsevier B.V.},

Thirty-nine studies were examined for this review: 56% were case studies or small sample studies, 13% were studies using larger samples, but no control or comparison condition, 13% used a comparison group (waiting list, placebo), 8% used a comparative treatment condition (usually in vivo expo- sure) and 13% used both. The specific phobias that were treated in these studies were acrophobia, aviophobia, claustrophobia, arachnophobia and fear of driving. The majority of these studies demonstrated that in virtuo exposure is effective and constitutes an interesting alternative to in vivo exposure. However, as the area is still taking its first steps, more studies with stronger methodological validity (control and comparative treatment conditions) are needed. © Virtual Reality Medical Institute.},

abstract = {Many outcome studies have been conducted to assess the efficacy of virtual reality in the treatment of specific phobias. However, most studies used self-report data. The addition of objective measures of arousal and information processing mechanisms would be a valuable contribution in order to validate the usefulness of virtual reality in the treatment of anxiety disorders. The goal of this study was to document the impact of virtual reality exposure (VRE) on cardiac response and automatic processing of threatening stimuli. Twenty-eight adults suffering from arachnophobia were assessed and received an exposure-based treatment using virtual reality. General outcome and specific processes measures included a battery of standardized questionnaires, a pictorial emotional Stroop task, a behavioral avoidance test and a measure of participants' inter-beat intervals (IBI) while they were looking at a live tarantula. Assessment was conducted before and after treatment. Repeated measures ANOVAs revealed that therapy had a positive impact on questionnaire data, as well as on the behavioral avoidance test. Analyses made on the pictorial Stroop task showed that information processing of spider-related stimuli changed after treatment, which also indicates therapeutic success. Psychophysiological data also showed a positive change after treatment, suggesting a decrease in anxiety. In sum, VRE led to significant therapeutic improvements on objective measures as well as on self-report instruments. © 2005 Springer Science+Business Media, Inc.},
