Lunar Lies: The Impact of Informational Framing and Individual Differences in Shaping Conspiracist Beliefs About the Moon Landings

Two studies examined the role of informational framing and individual differences on acceptance of the moon landings conspiracy theory (CT). In Study 1, participants were randomly assigned to one of three experimental groups in which they were exposed to different forms of information about the moon landings CT. Results showed that information critical of the moon landings CT resulted in attenuated conspiracist beliefs and that information supportive of the CT resulted in stronger conspiracist beliefs. In addition, stronger belief in the moon landings CT was associated with participants' belief in other CTs and openness to experience. In Study 2, participants completed a survey measuring their belief in the moon landings CT and a range of individual difference factors. Results showed that acceptance of the moon landings CT was associated with the adoption of a conspiracist worldview and schizotypal tendencies. Possibilities for conceptualizing the functional roles played by CTs are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

Digit ratio (2D:4D) and sex-role orientation: Further evidence and meta-analysis

Three new studies (N = 132, 623, 1112) did not yield hypothesized associations between digit ratio (2D:4D), an assumed negative correlate of prenatal testosterone, and psychometrically measured sex-role orientation (positive association with femininity, negative ones with masculinity and masculinity-femininity difference scores) among heterosexuals of either sex. Meta-analysis of the pertinent literature (N = 6311, 28 studies from 10 countries, 46% unpublished) showed only men’s (but not women’s) left-hand (but not right-hand) 2D:4D reliably related as expected (positively) to femininity. This effect was tiny (0.14% attributable variance) and possibly non-robust (crucially dependent on one large study included). Hence, the cumulative evidence does not support systematic, robust, noteworthy within-sex correlations between 2D:4D and the masculinity/femininity personality dimensions.

Grouping in the shine-through effect

How the elements of a visual scene are grouped into objects is one of the most fundamental but still poorly understood questions in visual neuroscience. Most investigations of perceptual grouping focus on static stimuli, neglecting temporal aspects. Using a masking paradigm, we show that the neural mechanisms underlying grouping seem to be both fast and complex. For example, a vernier target was followed by, first, a briefly presented grating and, then, a long-lasting, extended grating. Under these conditions, the briefly presented grating is hardly visible. Still, vernier discrimination strongly changed with the number of elements of the briefly displayed grating being worst for small gratings. In accordance with a neural network model of masking, we propose that the edges of the briefly presented grating and the vernier interfere in spite of the short presentation time. We suggest that this fast edge processing is a first step for unconscious grouping processes.
