Field studies on HIV risk suggest that people may rely on impressions they have about the safety of their partner at the dispense of more objective risk protection strategies. In this study, ERP recordings were used to investigate the brain mechanisms that give rise to such impressions. First, in an implicit condition, participants viewed a series of… (More)
Field studies on HIV risk perception suggest that people may rely on impressions they have about the safety of their partner. Previous studies show that individuals perceived as "risky" regarding HIV elicit a differential brain response in both earlier (~200-350 ms) and later (~350-700 ms) time windows compared to those perceived as safe. This raises the… (More)

Die Röntgenstrahlung entsteht durch Abbremsung von Elektronen in einem wassergekühlten Kupfertarget. Da der einfallende Strahl nicht bewegt werden kann, wird die Probe um einen Winkel… (More)
BACKGROUND Extremity injuries (EI) and dementia are important causes of long-term care (LTC), but they can also cause each other and are often present concurrently. Mobility-limiting EI can increase the risk of dementia, and dementia increases the risk for falls, which are often the cause of EI. When EI and dementia are present together, they can increase… (More)
4 ABSTRACT Previous research on health risk perception has revealed that people make snap judgments about potential health threats resulting from encounters with unacquainted people. Since HIV is still a dangerous threat in this context, many studies trying to broaden the understanding for the mechanisms underlying these judgments concentrated on this… (More)
BACKGROUND People do not use condoms consistently but instead rely on intuition to identify sexual partners high at risk for human immunodeficiency virus (HIV) infection. The present study examined gender differences of intuitive impressions about HIV risk. METHODS Male and female perceivers evaluated portraits of unacquainted male and female targets… (More)
