Categorization difficulty is associated with negative evaluation in the “uncanny valley” phenomenon

Human observers often experience strongly negative impressions of human‐like objects falling within a particular range of visual similarity to real humans (the “uncanny valley” phenomenon). We hypothesized that negative impressions in the uncanny valley phenomenon are related to a difficulty in object categorization. We produced stimulus images by morphing two of each of real, stuffed, and cartoon human face images (Experiment 1). Observers were asked to categorize each of these images as either category and evaluated the likability of the image. The results revealed that the longest latency, the highest ambiguity in categorization, and the lowest likability score co‐occurred at consistent morphing percentages. Similar results were obtained even when we employed stimulus images that were created by morphing two of each of real, stuffed, and cartoon dog images (Experiment 2). However, the effect of categorization difficulty on evaluation was weak when two real human faces were morphed (Experiment 3). These results suggest that the difficulty in categorizing an object as either of two dissimilar categories is linked to negative evaluation regardless of whether the object is human‐related or not.     

Object processing for action across childhood

Human adults process and select the opportunities for action in their environment rapidly, efficiently, and effortlessly. While several studies have revealed substantial improvements in object recognition skills, motor abilities, and control over the motor system during late childhood, surprisingly little is known about how object processing for action develops during this period. This study addresses this issue by investigating how the ability to ignore actions potentiated by a familiar utensil develops between ages 6 and 10 years. It is the first study to demonstrate that (1) the mechanisms that transform a graspable visual stimulus into an object‐appropriate motor response are in place by the sixth year of life and (2) graspable features of an object can facilitate and interfere with manual responses in an adult‐like manner by this age. The results suggest that there may be distinct developmental trajectories for the ability to ignore motor responses triggered by visual affordances and the stimulus response compatibility effects typically assessed with Simon tasks.     

Art - A Feasible Illusion

This article discusses the approximation between art and psychoanalysis, considering both as manifestations of the unconscious. Art is viewed as a successful instinctual substitute which differs from the symptom in terms of effectiveness. A work of art is the symbolic universe of the artist, who, by withdrawing into the world of imagination, encounters the pathways of reality. Artistic manifestation is not interpretable, however it communicates with the observer who may also find satisfaction for his own unconscious desires therein.     

Freud and narcissism: Developing links for inclusion of the ‘object’

Abstract

The problematic of narcissism in the way Freud visualized forces us to acknowledge the dualism of drives inside the subject; the object relations theory then builds up on the inherent need and the structuring potential of the object. The paper traces the growth of this concept in Freud's thinking in a bid to show how the object's otherness is not fully metabolized within the Freudian corpus. On the other hand, recent criticisms of object relations theory point to the perfunctory role ascribed to Freud's most radical discovery of the dualism of drives. Winnicott, Laplanche and Green have all developed theories that have provided pertinent rejoinders to the problematic of narcissism and object relations. The paper discusses how deconstructing and “going back over Freud” helps us to redefine object relations and give the drive functioning due importance. Hence the main thesis of the paper – that of narcissism – reveals the decentered subject's tussle with itself and with the alienness emanating from the object's otherness. If used creatively, ideas such as “otherness”, “objectalizing function” and Green's conceptualization of the clinical significance of negative and positive narcissism then seek to enrich the theorization on narcissism.     

Testing the exclusivity effect in location memory

There is growing literature exploring the possibility of parallel retrieval of location memories, although this literature focuses primarily on the speed of retrieval with little attention to the accuracy of location memory recall. Baguley, Lansdale, Lines, and Parkin (2006) found that when a person has two or more memories for an object's location, their recall accuracy suggests that only one representation can be retrieved at a time (exclusivity). This finding is counterintuitive given evidence of non-exclusive recall in the wider memory literature. The current experiment explored the exclusivity effect further and aimed to promote an alternative outcome (i.e., independence or superadditivity) by encouraging the participants to combine multiple representations of space at encoding or retrieval. This was encouraged by using anchor (points of reference) labels that could be combined to form a single strongly associated combination. It was hypothesised that the ability to combine the anchor labels would allow the two representations to be retrieved concurrently, generating higher levels of recall accuracy. The results demonstrate further support for the exclusivity hypothesis, showing no significant improvement in recall accuracy when there are multiple representations of a target object's location as compared to a single representation.     

Conscious and unconscious face recognition is improved by high-frequency rTMS on pre-motor cortex

Simulation process and mirroring mechanism appear to be necessary to the recognition of emotional facial expressions. Prefrontal areas were found to support this simulation mechanism. The present research analyzed the role of premotor area in processing emotional faces with different valence (positive vs. negative faces), considering both conscious and unconscious pathways. High-frequency rTMS (10 Hz) stimulation was applied to prefrontal area to induce an activation response when overt (conscious) and covert (unconscious) processing was implicated. Twenty-two subjects were asked to detect emotion/no emotion (anger, fear, happiness, neutral). Error rates (ERs) and response times (RTs) were considered in response to the experimental conditions. ERs and RTs decreased in case of premotor brain activation, specifically in response to fear, for both conscious and unconscious condition. The present results highlight the role of the premotor system for facial expression processing, supporting the existence of two analogous mechanisms for conscious and unconscious condition.     

From data through discount rates to the area under the curve

The rate of discounting future goods is a crucial factor in intertemporal trade-offs, upon which depends not only individual well-being but also that of our planet: How much privation now for a temperate future for our grandchildren? What is the best way to measure how the value of future goods decreases with its delay? The most accurate discount functions involve several covarying parameters, making interpretation equivocal. A universal and robust measure is the area under the discount curve, the AuC. The AuC of a hyperbolic discount function is a logarithmic function of the discount rate, k. The same integral also approximates the area under a hyperboloid function. A simple technique converts each datum into estimates of the discount rate, eliminating rogue data points in the process. These trimmed estimates are converted into areas and tested against data, where they succeed at predicting the AuC and its relation to log(k).     

‘And if not now,when?’: Spirituality,psychotherapy, politics

Abstract

Without collapsing distinct discourses into each other, the paper considers the linkages between spirituality, psychotherapy and politics. Changes are taking place in all three areas. Therapists who focus on the spiritual dimension as part of their ordinary work still tend to be marginalized. Similarly, the political dimensions of the client's experience often receive insufficient attention. The author offers an initial sketch of a new ‘anatomy of spirituality’: into social spirituality, democratic spirituality, craft spirituality, profane spirituality and spiritual sociality. He criticizes the practice of ‘safe therapy’, meaning therapy based on an object relations paradigm that represses the (incestuous) sexuality that lies at the heart both of the therapy encounter and the domain of spiritual values. The paper concludes with some thoughts about justice and an account of pertinent grassroots political developments.     

The infant and the infinite: On psychoanalytic faith – Bion,Meltzer and Kierkegaard

This paper discusses the meaning of psychoanalytic faith as a useful developmental concept, which applies to the therapeutic process in the consulting room as to other intimate educational experiences. Faith is a concept which has been little considered in relation to psychoanalysis, partly owing to semantic confusion with ‘the Faith’ as in religious or psychoanalytic dogma, and partly owing to the difficulty of defining or describing what it is, outside accepted jargon. Yet, faith is traditionally the gateway to experiencing the unknown – a psychoanalytic goal-demanding negative capability. It is suggested that philosophy and poetry, where the concept is more familiar, can provide psychoanalytic parallels for this particular type of learning from experience. The viewpoints of Bion, Meltzer and Kierkegaard are taken as contributing to a picture of how, in the psychoanalytic session, there may be a developmental encounter between the infant (patient) and the infinite (the transference process, rather than the analyst as a person).     

Dissociated deficits of visuo-spatial memory in near space and navigational space: Evidence from brain-damaged patients and healthy older participants

ABSTRACT

Defects confined to spatial memory can severely affect a variety of daily life activities, such as remembering the location of objects or navigating the environment, until now the skills involved have been mostly assessed with regard to the visual domain using traditional pencil and paper tests. Our aim was to test the efficacy of a recently developed psychometric instrument (Walking Corsi Test: WalCT) to assess the specific contribution of spatial memory to the complex task of retrieving route knowledge. The WalCT is a 3×2.5-m version of the well-known Corsi Block-tapping Test (CBT), in which patients are required to memorize (and replicate) a sequence of body displacements. We assessed the ability of left and right brain-damaged patients, as well as healthy young and senior controls, to perform both the CBT and the WalCT. Results showed differences related to age in the healthy individuals and specific functional dissociations in the brain-damaged patients. The double dissociations found in this study demonstrate the importance of having a task able to detect navigational disorders, because virtual reality tasks are often much too difficult for aged brain-damaged patients to perform.
