ABSTRACT

In recent years researchers have started to focus on lying about intentions (Granhag, 2010). In the present experiment participants were interviewed about their forthcoming trip. We tested the hypothesis that liars (N=43) compared to truth tellers (N=43) would give fewer details to unexpected questions about planning, transportation and the core event, but an equal amount or more detail to expected questions about the purpose of the trip. We also tested the hypothesis that participants who had previously experienced the intention (i.e., they had made such a trip before) would give more detail than those who had never experienced the intended action. The unexpected question hypothesis was supported, whereas the previous experience effect only emerged in interactions. The benefit of using different types of questions for lie detection purposes is discussed.

ABSTRACT

Bodily illusions offer an experimental method to investigate the origins and functional role of the sense of one's own body. Using the rubber hand illusion (RHI) we show that a representation of one's own body is implicitly used to calibrate perception of external objects. Twelve participants experienced the RHI while watching stimulation of a large or small glove simultaneously with stimulation of their own hand. They then grasped cylinders of identical size but varying weight. RHI with the large glove caused the cylinders to feel heavier. We suggest that an illusory increase in hand size made the subsequently grasped cylinder feel correspondingly small, evoking a size-weight illusion. Self-representation thus influenced exteroception. The sense of one's own body provides a fundamental reference for perception in general.

ABSTRACT

The authors conducted 2 studies to examine the stigmatization of the female and male body using photographic stimuli of real people. In the first study, 75 female and 55 male undergraduates rated a series of 50 photographs of women ranging in body mass index (BMI) on 3 items: gets teased, lonely, and lazy. Both male and female observers rated bodies on either side of BMI 19-20 kg/m2 higher for the gets teased and lonely items. For the lazy item, there was a clear pattern of greater stigmatization with increasing BMI. In the second study, 40 male and 40 female observers rated a series of photographs of the male body that varied in BMI and waist-to-chest ratio on the same items. Results showed that men and women judged overweight and more tubular men to be lazier, lonelier, and teased. These findings suggest that body size is an important characteristic to consider when examining body stigmatization among men and women. These results also show support for the beautiful-is-good bias.
