The Kiki-Bouba effect comprises a relation between two abstract figures and two non-words: the star-shaped figure is called 'Kiki' and the rounded figure 'Bouba'. The effect is explained by a sound-vision synaesthesia: certain sounds are associated with certain shapes in a non-arbitrary manner.When we asked the participants to decide which of the two figures, the star-shaped or the rounded one, to call yin and which yang, some 85% choose the star-shaped figure as yin. There are previous cases of synaesthesia where (...) personality is attributed to numbers or letters. In our results, the word Kiki is overall happy, clever, small, thin, young, unpleasant, and nervous. The starshaped figure is overall clever, tall, small, slim, nervous, unpleasant, and upper-class. That is, the correspondence above all concerns the qualifying adjectives clever, unpleasant, and nervous, as well as the physical appearance small and thin. This brings us to the fat-thin effect. Cinema, literature, comics, and children's programmes are full of contrasting figures: Don Quixote and Sancho Panza, Laurel and Hardy , Asterix and Obelix, Tintin and Captain Haddock, Bert and Ernie , or the Spanish comic about very naughty twin boys called Zipi and Zape . Our main conclusion is that first names and last names are not entirely arbitrary. There is a correspondence between names and physical characteristics and concepts . The Kiki-Bouba effect is a semantic one. (shrink)

In a variety of synaesthesia, photisms result from affect-laden stimuli as emotional words, or faces of familiar people. For R, who participated in this study, the sight of a familiar person triggers a mental image of "a human silhouette filled with colour". Subjective descriptions of synaesthetic experiences induced by the visual perception of people's figures and faces show similarities with the reports of those who claim to possess the ability to see the aura. It has been proposed that the purported (...) auric perception may be easily explained by the presence of a specific subtype of cross-modal perception. We analyse the subjective reports of four synaesthetes who experience colours in response to human faces and figures. These reports are compared with descriptions of alleged auric phenomena found in the literature and with claims made by experts in esoteric spheres. The discrepancies found suggest that both phenomena are phenomenologically and behaviourally dissimilar. (shrink)
