In early 2015, a public debate about a perceptual phenomenon that impressively demonstrated the subjective nature of human perception was running round the globe: the debate about #TheDress, a poorly lit photograph of a lace dress that was perceived as white–gold by some, but as blue–black by others. In the present research (N¼48), we found that the perceptual difference between white–gold perceivers (n1¼24, 12 women, Mage¼25.4 years) and blue–black perceivers (n2¼24, 12 women, Mage¼24.3 years) decreased significantly when the illumination information provided by the original digital photo was reduced by means of image scrambling (Experiment 1). This indicates that the illumination information is one potentially important factor contributing to the color ambiguity of #TheDress—possibly by amplification of a slight principal difference in psychophysics of color perception which the two observer groups showed for abstract uniformly colored fields displaying a white–blue ambiguity (Experiment 2).
The folded paper-size illusion is as easy to demonstrate as it is powerful in generating insights into perceptual processing: First take two A4 sheets of paper, one original sized, another halved by folding, then compare them in terms of area size by centering the halved sheet on the center of the original one! We perceive the larger sheet as far less than double (i.e., 100%) the size of the small one, typically only being about two thirds larger—this illusion is preserved by rotating the inner sheet and even by aligning it to one or two sides, but is dissolved by aligning both sheets to three sides, here documented by 88 participants’ data. A potential explanation might be the general incapability of accurately comparing more than one geometrical dimension at once—in everyday life, we solve this perceptual-cognitive bottleneck by reducing the complexity of such a task via aligning parts with same lengths.
Etwa ein Drittel der Personen, die widrigen bis traumatischen Umständen ausgesetzt sind, entwickeln psychische Probleme. Statt zu fragen, warum Menschen krank werden, lenkt das Konzept der Resilienz die Aufmerksamkeit auf die anderen zwei Drittel. Wie gelingt es ihnen, schwierige Bedingungen zu meistern ohne unter anhaltenden Beeinträchtigungen zu leiden? Welche Bedeutung hat das in der heutigen Arbeitswelt? Und wie kann durch Coaching die Resilienz beeinflusst werden? Der aktuelle Forschungsstand erlaubt noch keine abschließenden Antworten, zeigt aber Ansatzpunkte zur Erfassung und Entwicklung von Resilienz im Rahmen des Coachings.
