Aesthetic Judgements of Abstract Dynamic Configurations

To date, aesthetic preference for abstract patterns has mainly been examined in the relation to static stimuli. However, dynamic art forms (e.g., motion pictures, kinetic art) are arguably more powerful in producing emotional responses. To start the exploration of aesthetic preferences for dynamic stimuli (stripped of meaning and context) we conducted three experiments. Symmetrical or random configurations were created. Each line element had a local rotation, and the whole configuration also underwent a global transformation (horizontal translation, rotation, expansion, horizontal shear). Participants provided explicit preference ratings for these patterns. As expected results showed a preference for dynamic symmetrical patterns over random. When global transformations were compared, expansion was the preferred dynamic transformation whilst participants liked the horizontal shear transformation the least. Overall, these results show that preference for symmetry persists and is enhanced for dynamic stimuli, and that there are systematic preferences for global transformations.</jats:p

How Men and Women Respond to Hypothetical Parental Discovery: The Importance of Genetic Relatedness

Paternal uncertainty has shaped human behavior both in evolutionary and cultural terms. There has been much research investigating parenting as a function of genetic relatedness to the child, with a focus on male behavior, but the nature of these sex differences is hard to evaluate. We devised a hypothetical scenario that was as similar as possible for men and women to test whether, even in such a scenario, sex differences would remain strong. Participants were presented with the discovery that a child that s/he believed to be theirs was not carrying their own genes. Irrespective of sex, participants ( n = 1007) were more upset when the baby was not genetically related to them than when the child was genetically related but the sex gamete was not from a chosen donor. Women were more upset than men in both scenarios, but were more likely to want to keep the baby. The results are discussed with reference to evolved and rational mechanisms affecting parenting

Reasoning about visibility in mirrors: A comparison between a human observer and a camera

Human observers make errors when predicting what is visible in a mirror. This is true for perception with real mirrors as well as for reasoning about mirrors shown in diagrams. We created an illustration of a room, a top-down map, with a mirror on a wall, and objects (nails) on the opposite wall. The task was to select which nails were visible in the mirror from a given position (viewpoint). To study the importance of the social nature of the viewpoint we divided the sample (N=108) in two groups. One group (N=54) were tested with a scene in which there was the image of a person. The other group (N=54) were tested with the same scene but with a camera replacing the person. Participants were instructed to think about what would be captured by a camera on a tripod. This manipulation tests the effect of social perspective taking in reasoning about mirrors. As predicted, performance on the task shows an overestimation of what can be seen in a mirror, and a bias to underestimate the role of the different viewpoints, i.e. a tendency to treat the mirror as if it captures information independently of viewpoint. In terms of the comparison between person and camera there were more errors for the camera, suggesting an advantage for evaluating a human viewpoint as opposed to an artificial viewpoint. We suggest that social mechanisms may be involved in perspective taking in reasoning rather than in automatic attention allocation

False beliefs and naive beliefs: They can be good for you

Naive physics beliefs can be systematically mistaken. They provide a useful test-bed because they are common, and also because their existence must rely on some adaptive advantage, within a given context. In the second part of the commentary we ask questions about when a whole family of misbeliefs should be considered together as a single phenomenon

Clustering leads to underestimation of numerosity, but crowding is not the cause

Mario Ponzo (1928) on perception of numerosity:A translation and commentary

Ponzo is a familiar name in psychology because of the illusion that takes his name. He had a long and productive career in Italy, and some of his work was translated for international journals already in his lifetime. However, few of these papers are available in English. We provide a commentary that considers how his name came to be associated with an illusion he did not discover. We explain the content of several papers, some of which are often cited in a wrong context in the literature (i.e., papers on touch mentioned in relation to the Ponzo illusion). More importantly, we discuss his contribution to the study of perceived numerosity, and provide a full translation of his important 1928 paper, including a redrawing of its 28 illustrations

Attentional interference is modulated by salience not sentience

Spatial cueing of attention occurs when attention is oriented by the onset of a stimulus or by other information that creates a bias towards a particular location. The presence of a cue that orients attention can also interfere with participants’ reporting of what they see. It has been suggested that this type of interference is stronger in the presence of socially-relevant cues, such as human faces or avatars, and is therefore indicative of a specialised role for perspective calculation within the social domain. However, there is also evidence that the effect is a domain-general form of processing that is elicited equally with non-social directional cues. The current paper comprises four experiments that systematically manipulated the social factors believed necessary to elicit the effect. The results show that interference persists when all social components are removed, and that visual processes are sufficient to explain this type of interference, thus supporting a domain-general perceptual interpretation of interference

Phenomenology, Quantity, and Numerosity.

There are many situations in which we interact with collections of objects, from a crowd of people to a bowl of blackberries. There is an experience of the quantity of these items, although not a precise number, and we have this impression quickly and effortlessly. It can be described as an expressive property of the whole. In the literature, the study of this sense of numerosity has a long history, which is reviewed here with examples. I argue that numerosity is a direct perceptual experience, and that all experiences of numerosity, not only estimations, are affected by perceptual organisation
