Innovative Moments as Developmental Change Levels: A Case Study on Meaning Integration in the Treatment of Depression

Innovative moments are alternative meanings to the problems expressed by clients and are organized into three levels. This study analyzes if these levels are not only change markers related to symptomatology outcomes, but also gradual steps in meaning development. A thematic analysis was carried out in a case of depression treated with narrative therapy. Results revealed three themes that evolved from level 1 to level 3. Levels 1 and 2 corresponded to one specific theme and almost all level 3 integrated different themes (polythematic). Level 3 innovative moments might be an integrative bridge allowing the construction of a more adaptive meaning framework.     

A Muslim President? Misperceptions of Barack Obama's Faith in the 2008 Presidential Campaign

Rumors that President Barack Obama is a Muslim were rampant during the 2008 presidential campaign and continued well into his presidency. These rumors were widely believed, were electorally consequential, and are part of a growing trend of politically motivated misconceptions. Thus, relying principally on the theory of motivated reasoning, we examine the factors that shaped citizens’ beliefs about and responses to messages about Obama's faith. Using an original survey experiment and data from the 2008–2009 American National Election Study panel, we show that citizens’ responses to rumors about Obama's religion were shaped by political predispositions, political awareness, and their interactions. Identification of Obama with Islam was most widespread, and the cues encouraging such identification were most successful, among individuals with low levels of political awareness, conservative and Republican identifications, and negative views of cultural out‐groups. Viewing Obama as Muslim was significantly less prevalent among people with high levels of awareness and with the opposite set of predispositions.     

Background surface and horizon effects in the perception of relative size and distance

The projected height of an object in a scene relative to a ground surface influences its perceived size and distance, but the effect of height should change when the object is moved above the horizon. In four experiments, observers judged relative size or relative distance for pairs of objects varying in height with respect to the horizon. Higher objects equal in projected size were judged larger below the horizon, but the relative size effect was reversed either when one object was on the horizon and one was above the horizon or when both objects were above the horizon. With the real horizon not explicitly present in the display, relative size judgements were affected both by the boundary of the visible surface and the vanishing point implied by the converging lines. For relative distance judgements, the higher object was judged more distant regardless of the height of the objects relative to the perceptual horizon, resulting in a reversal of the relation between size and distance judgements for objects above the horizon.     

Predominance of ground over ceiling surfaces in binocular rivalry

The superiority of ground surfaces over ceiling surfaces in determining the representation of the visual world, demonstrated in several studies of visual perception and visual search, has been attributed to a preference for top-away projections resulting from ecological constraints. Recent research on binocular rivalry indicates that ecological constraints affect predominance relations. The present study considered whether there is a difference in predominance between ground and ceiling surfaces. In Experiment 1, we examined whether a ground surface would dominate a ceiling surface when one surface was presented to each eye. In Experiment 2, we used an eye-swapping paradigm to determine whether a ground surface would come to dominance faster than a ceiling surface when presented to the suppressed eye. The eye-swapping paradigm was used again in Experiment 3, but the ground and ceiling planes were replaced with frontal planes with similar variations in texture density. The results of these experiments indicate that ground surfaces are predominant over ceiling surfaces, with this predominance affecting both the dominance and suppression phases of binocular rivalry. This superiority of ground planes is independent of image properties such as the increase or decrease in texture density from the lower half to the upper half of the images.     

Using leap motion to investigate the emergence of structure in speech and language

In evolutionary linguistics, experiments using artificial signal spaces are being used to investigate the emergenceof speech structure. These signal spaces need to be continuous, non-discretized spaces from which discrete unitsand patterns can emerge. They need to be dissimilar from—but comparable with—the vocal tract, in order tominimize interference from pre-existing linguistic knowledge, while informing us about language. This is a hardbalance to strike. This article outlines a new approach that uses the Leap Motion, an infrared controller that canconvert manual movement in 3d space into sound. The signal space using this approach is more flexible than signalspaces in previous attempts. Further, output data using this approach is simpler to arrange and analyze. Theexperimental interface was built using free, and mostly open- source libraries in Python. We provide our sourcecode for other researchers as open source.
