The power of pictures: Vertical picture angles in power pictures
Abstract:
Conventional wisdom suggests that variations in vertical picture angle cause the subject to appear more powerful when depicted from below and less powerful when depicted from above. However, do the media actually use such associations to represent individual differences in power? We argue that the diverse perspectives of evolutionary, social learning, and embodiment theories all suggest that the association between verticality and power is relatively automatic and should, therefore, be visible in the portrayal of powerful and powerless individuals in the media. Four archival studies (with six samples) provide empirical evidence for this hypothesis and indicate that a salience power context reinforces this effect. In addition, two experimental studies confirm these effects for individuals producing media content. We discuss potential implications of this effect
Low fingertip temperature rebound measured by digital thermal monitoring strongly correlates with the presence and extent of coronary artery disease diagnosed by 64-slice multi-detector computed tomography
Previous studies showed strong correlations between low fingertip temperature rebound measured by digital thermal monitoring (DTM) during a 5Ā min arm-cuff induced reactive hyperemia and both the Framingham Risk Score (FRS), and coronary artery calcification (CAC) in asymptomatic populations. This study evaluates the correlation between DTM and coronary artery disease (CAD) measured by CT angiography (CTA) in symptomatic patients. It also investigates the correlation between CTA and a new index of neurovascular reactivity measured by DTM. 129 patients, age 63Ā Ā±Ā 9Ā years, 68% male, underwent DTM, CAC and CTA. Adjusted DTM indices in the occluded arm were calculated: temperature rebound: aTR and area under the temperature curve aTMP-AUC. DTM neurovascular reactivity (NVR) index was measured based on increased fingertip temperature in the non-occluded arm. Obstructive CAD was defined as ā„50% luminal stenosis, and normal as no stenosis and CACĀ =Ā 0. Baseline fingertip temperature was not different across the groups. However, all DTM indices of vascular and neurovascular reactivity significantly decreased from normal to non-obstructive to obstructive CAD [(aTR 1.77Ā Ā±Ā 1.18 to 1.24Ā Ā±Ā 1.14 to 0.94Ā Ā±Ā 0.92) (PĀ =Ā 0.009), (aTMP-AUC: 355.6Ā Ā±Ā 242.4 to 277.4Ā Ā±Ā 182.4 to 184.4Ā Ā±Ā 171.2) (PĀ =Ā 0.001), (NVR: 161.5Ā Ā±Ā 147.4 to 77.6Ā Ā±Ā 88.2 to 48.8Ā Ā±Ā 63.8) (PĀ =Ā 0.015)]. After adjusting for risk factors, the odds ratio for obstructive CAD compared to normal in the lowest versus two upper tertiles of FRS, aTR, aTMP-AUC, and NVR were 2.41 (1.02ā5.93), PĀ =Ā 0.05, 8.67 (2.6ā9.4), PĀ =Ā 0.001, 11.62 (5.1ā28.7), PĀ =Ā 0.001, and 3.58 (1.09ā11.69), PĀ =Ā 0.01, respectively. DTM indices and FRS combined resulted in a ROC curve area of 0.88 for the prediction of obstructive CAD. In patients suspected of CAD, low fingertip temperature rebound measured by DTM significantly predicted CTA-diagnosed obstructive disease
To which world regions does the valenceādominance model of social perception apply?
Over the past 10 years, Oosterhof and Todorovās valenceādominance model has emerged as the most prominent account of
how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social
judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether
these findings apply to other regions. We addressed this question by replicating Oosterhof and Todorovās methodology across
11 world regions, 41 countries and 11,570 participants. When we used Oosterhof and Todorovās original analysis strategy,
the valenceādominance model generalized across regions. When we used an alternative methodology to allow for correlated
dimensions, we observed much less generalization. Collectively, these results suggest that, while the valenceādominance
model generalizes very well across regions when dimensions are forced to be orthogonal, regional differences are revealed
when we use different extraction methods and correlate and rotate the dimension reduction solution.C.L. was supported by the Vienna Science and Technology Fund (WWTF VRG13-007);
