Textures that we like to touch: An experimental study of aesthetic preferences for tactile stimuli

We report two experiments designed to investigate the nature of aesthetic preferences for tactile textures in humans. In Experiment 1, the participants rated their preference for a range of actively and passively explored textures presented on their hands and on their cheeks. The results revealed that those textures that were subjectively-rated as smoother were preferred over those that were rated as rougher. Moreover, certain textures were disliked more during active than during passive stimulation. In Experiment 2, the speed of tactile stimulation was controlled in order to elicit vigorous responses from C-tactile fibers (present only in hairy skin), which are thought to play a central role in pleasant aspects of touch. The results revealed that textures were preferred when presented on the hairy skin of the forearm than on the glabrous palm of the hand. These results provide preliminary evidence regarding people’s preferences for different attributes of tactile surface.     

The role of analytic thinking in moral judgements and values

While individual differences in the willingness and ability to engage analytic processing have long informed research in reasoning and decision making, the implications of such differences have not yet had a strong influence in other domains of psychological research. We claim that analytic thinking is not limited to problems that have a normative basis and, as an extension of this, predict that individual differences in analytic thinking will be influential in determining beliefs and values. Along with assessments of cognitive ability and style, religious beliefs, and moral values, participants judged the wrongness of acts considered disgusting and conventionally immoral, but that do not violate care- or fairness-based moral principles. Differences in willingness to engage analytic thinking predicted reduced judgements of wrongness, independent of demographics, political ideology, religiosity, and moral values. Further, we show that those who were higher in cognitive ability were less likely to indicate that purity, patriotism, and respect for traditions and authority are important to their moral thinking. These findings are consistent with a “Reflectionist” view that assumes a role for analytic thought in determining substantive, deeply-held human beliefs and values.     

Factors that affect action possibility judgements: Recent experience with the action and the current body state

It has been suggested that action possibility judgements are formed through a covert simulation of the to-be-executed action. We sought to determine whether the motor system (via a common coding mechanism) influences this simulation, by investigating whether action possibility judgements are influenced by experience with the movement task (Experiments 1 and 2) and current body states (Experiment 3). The judgement task in each experiment involved judging whether it was possible for a person's hand to accurately move between two targets at presented speeds. In Experiment 1, participants completed the action judgements before and after executing the movement they were required to judge. Results were that judged movement times after execution were closer to the actual execution time than those prior to execution. The results of Experiment 2 suggest that the effects of execution on judgements were not due to motor activation or perceptual task experience—alternative explanations of the execution-mediated judgement effects. Experiment 3 examined how judged movement times were influenced by participants wearing weights. Results revealed that wearing weights increased judged movement times. These results suggest that the simulation underlying the judgement process is connected to the motor system, and that simulations are dynamically generated, taking into account recent experience and current body state.     

Cognitive processing of moral and social judgements: A comparison of offenders,students, and control participants

Examining cognitive processes related to offenders’ moral and social judgements is important in order to better understand their criminal behaviour. In the present study, 30 offenders, 30 students, and 24 control participants were administered the moral-conventional judgements computer task, which requires responding under strict time constraints. Participants read scenarios and were asked to judge whether the act was acceptable or unacceptable when rules were either assumed or removed. Additionally, participants completed an executive function (EF) task in order to examine the relation between EF and moral and social judgements. The findings revealed that, as expected, controls and students had faster reaction times (RTs) and a higher percentage of normative judgements than offenders. Additionally, offenders had a low percentage of normative judgements, particularly in the conventional rule removed condition. Finally, RTs of moral and conventional judgements in most conditions were related to EF among students but not controls or offenders. We conclude that offenders, as compared to controls and students, may rely more on rule-oriented responding and may rely less on EF when making moral and social judgements.     

From bad to worse: Symbolic equivalence and opposition in fear generalisation

The present study compared the impact of symbolic equivalence and opposition relations on fear generalisation. In a procedure using nonsense words, some stimuli became symbolically equivalent to an aversively conditioned stimulus while others were symbolically opposite. The generalisation of fear to symbolically related stimuli was then measured using behavioural avoidance, retrospective unconditioned stimulus expectancy and stimulus valence ratings. Equivalence relations facilitated fear generalisation while opposition relations constrained generalisation. The potential clinical implications of symbolic generalisation are discussed.     

Extreme Traumatisation: Strategies for Mental Survival

Sincerity: a Study in the Atmosphere of Human Relations, a previously unpublished book, appearing in D. Meltzer's Collected Papers, explores The Dwarfs, The Birthday Party and The Homecoming by Harold Pinter, both the capacity to communicate genuine emotion and its limitation by the subject's inability to say-what-he-means, because of rigidity and coldness, and to mean-what-he-says, because of an integrated narcissistic structure. That the language of dreams is perhaps the lingua franca of emotionality and the key to aesthetics is the book's conclusion, with a clear indication of the books to come. This article surveys the relevance of the notion of sincerity in Meltzer's further work, in its clinical and metapsychological aspects.     

Birds of a feather… Generalization of facial structures following massive familiarization

Three experiments examined the effects of symmetry and complexity, as facial structures, on the aesthetic judgments of faces, and how these effects are modulated by moderate or massive familiarization. Results showed that symmetrical faces were judged as more attractive than nonsymmetrical faces, and simple faces were judged as more attractive than complex faces—with complexity defined as the number of facial elements. Complexity in faces seemed to have overridden the usually positive effects of facial symmetry. Moreover, while moderate familiarization did not modulate the effects, massive familiarization to a specific face type resulted in structural generalization effects: participants provided higher aesthetic judgments to faces that were new, but similarly structured to those which they were familiarized. This latter result contrasts previous studies that have found structural contrast effects following familiarization to meaningless, abstract stimuli. Taken together, these results reflect the greater biological and social significance of faces as compared to other objects in the world. They also show that people are drawn to those with familiar characteristics.     

Kant on Truth-Aptness

Many scholars claimed that, according to Immanuel Kant, some judgements lack a truth-value: analytic judgements, judgements about items of which humans cannot have experience, judgements of perception, and non-assertoric judgements. However, no one has undertaken an extensive examination of the textual evidence for those claims.

Based on an analysis of Kant's texts, I argue that: ? according to Kant, only judgements of perception are not truth-apt. All other judgements are truth-apt, including analytic judgements and judgements about items of which humans cannot have experience.

? Kant sometimes states that truth-apt judgements are actual bearers of truth or falsity only when they are taken to state what is actually the case. Kant calls these judgements assertoric. Other texts ascribe truth and falsity to judgements, regardless of whether they are assertoric.

Kant's views on truth-aptness raise challenges for correspondentist and coherentist interpretations of Kant's theory of truth; they rule out the identification of Kant's crucial notion of objective validity with truth-aptness; and they imply that Kant was not a verificationist about truth or meaning.     

When a Picasso is a “Picasso”: The entry point in the identification of visual art

We investigated whether art is distinguished from other real world objects in human cognition, in that art allows for a special memorial representation and identification based on artists’ specific stylistic appearances. Testing art-experienced viewers, converging empirical evidence from three experiments, which have proved sensitive to addressing the question of initial object recognition, suggest that identification of visual art is at the subordinate level of the producing artist. Specifically, in a free naming task it was found that art-objects as opposed to non-art-objects were most frequently named with subordinate level categories, with the artist’s name as the most frequent category (Experiment 1). In a category-verification task (Experiment 2), art-objects were recognized faster than non-art-objects on the subordinate level with the artist’s name. In a conceptual priming task, subordinate primes of artists’ names facilitated matching responses to art-objects but subordinate primes did not facilitate responses to non-art-objects (Experiment 3). Collectively, these results suggest that the artist’s name has a special status in the memorial representation of visual art and serves as a predominant entry point in recognition in art perception.     

The dark side of cognitive illusions: When an illusory belief interferes with the acquisition of evidence‐based knowledge

Cognitive illusions are often associated with mental health and well‐being. However, they are not without risk. This research shows they can interfere with the acquisition of evidence‐based knowledge. During the first phase of the experiment, one group of participants was induced to develop a strong illusion that a placebo medicine was effective to treat a fictitious disease, whereas another group was induced to develop a weak illusion. Then, in Phase 2, both groups observed fictitious patients who always took the bogus treatment simultaneously with a second treatment which was effective. Our results showed that the group who developed the strong illusion about the effectiveness of the bogus treatment during Phase 1 had more difficulties in learning during Phase 2 that the added treatment was effective.
