‘Goals’ are not an integral component of imitation

Several theories suggest that actions are coded for imitation in terms of mentalistic goals, or inferences about the actor’s intentions, and that these goals solve the correspondence problem by allowing sensory input to be translated into matching motor output. We tested this intention reading hypothesis against general process accounts of imitation using the pen-and-cups task. The task has three components: participants place a pen in one of two cups, using their right or left hand, and one of two grips. Previous research has revealed a colour minimum error pattern; when one of the components is differentially coloured (e.g., one cup is red and the other blue), accuracy is greatest on the coloured dimension. We found the colour minimum error pattern, not only in the standard version of the task, where participants imitate the actions of a human model, but also in three novel variants of the task, in which participants responded on the basis of spatial or arbitrary stimulus–response mappings to ‘geometric’, non-biological stimuli. These stimuli do not afford the attribution of intentions, and therefore our results support generalist theories of imitation by showing that the colour minimum error pattern is due, not to intention reading, but to the operation of task-general processes of perception, attention and motor control.     

Sustained vs. transient cognitive control: Evidence of a behavioral dissociation

This study assessed whether two well known effects associated with cognitive control, conflict adaptation (the Gratton effect) and conflict context (proportion congruent effects), reflect a single common or separate control systems. To test this we examined if these two effects generalized from one kind of conflict to another by using a combined-conflict paradigm (involving the Simon and Spatial Stroop tasks) and manipulating the proportion of congruent to incongruent trials for one conflict (Simon) but not the other (Spatial Stroop). We found that conflict adaptation effects did not generalize, but the effect of conflict context did. This contrasting pattern of results strongly suggests the existence of two separate attentional control systems, one transient and responsible of online regulation of performance (conflict adaptation), the other sustained and responsible for conflict context effects.     

Deweyan Multicultural Democracy,Rortian Solidarity,and the Popular Arts: Krumping into Presence

Curiously, while the efficacy of the arts for the development of multicultural understandings has long been theorized, empirical studies of this effect have been lacking. This essay recounts our combined empirical and philosophical study of this issue. We explicate the philosophical considerations that shaped the development of the arts course we studied, which was grounded in rather traditional humanist educational thought, informed by Deweyan considerations for pedagogy and multiculturalism. We also provide an overview of the course and of the study design: the ways in which the course worked to teach aesthetic theory through a combination of popular and canonical works, and the ways in which it sought to instill a sense of cross-cultural appreciation and solidarity among students through the inclusion of art from different cultures and generations. We then share our research findings and our return to the realm of philosophy to interpret them. Our postcolonial analysis incorporates emerging discussions of the arts as a tool for resistance and dialogue within the system of public education, and revisit and reconsider the very concept of education for pluralistic democracy. This approach problematizes traditional conceptions of pluralism, in which an attempt is made to dissolve difference in a common understanding, and instead advocates that works from among the contemporary popular arts and works drawn from the artistic “canon” alike must be considered and employed for their instrumental value to the educational process—especially for their ability to prompt an intersubjectivity that is accompanied by a heightened awareness of difference.     

Structural relaxation and rejuvenation in a metallic glass induced by shot-peening

The metallic glass Pd₄₀Cu₃₀Ni₁₀P₂₀ in as-cast or pre-annealed states was shot-peened successively at room temperature or at 77 K. The structural state of the glass was characterized by the relaxation spectrum measured in a differential scanning calorimeter. Mechanically induced relaxation of the as-cast glass and mechanically induced rejuvenation of pre-annealed samples are both more evident at 77 K than at 298 K, enabling deductions about the underlying mechanisms. The relaxation spectrum of the glass as a function of temperature displays two broad maxima, which occurring at the higher temperature is attributed to the part of the free-volume distribution associated with flow defects. In samples shot-peened at 77 K, the stored energy after deformation can be as high as 20% of the cold work. Shot-peening simultaneously generates flow defects within shear bands and destroys them in the matrix between bands: whose effect dominates is principally dependent on the initial state of relaxation of the glass. Shot-peening of partially crystallized samples appears capable of breaking up and dispersing crystallites without inducing any further significant crystallization.     

The Many Senses of Imagination and the Manifestation of Fiction: A View from Husserl’s Phenomenology of Phantasy

The systematic importance of the eidetic account of phantasy for Husserlian phenomenology in general is undisputed, but whether this account can be relevant for Aesthetics has often been put into question. In this paper I argue that Husserl’s rich phenomenology of phantasy, and in particular his account of perceptual phantasy, can nevertheless significantly enhance our understanding of how we recognize and imaginatively participate in artistic fictions. Moreover, I show how Husserl’s peculiar formulation of a non-intuitive phantasy at stake in artistic representation anticipates some uses of the imagination in Aesthetics suggested by Ernst Gombrich and Kendall Walton.     

Entrevista con J. D. Frank

RESUMEN

Jerome Frank, posiblemente el autor más provocativo en la línea de considerar que las psicoterapias pueden ser placebos o que éstos deben considerarse como auténticas terapias, responde en la entrevista a algunas de las cuestiones que su reconocimiento de los factores comunes a todas las terapias han planteado a otros profesionales. Comienza explicando que desde la publicación de Persuasion and Healing se han acumulado más datos a favor de su hipótesis de la desmoralización, e introduce algunas clarificaciones terminológicas en relación con el “efecto placebo”. Seguidamente aborda, entre otras, cuestiones tales como las características que se deben considerar al diseñar un grupo control placebo, cómo deben emplearse éstos en el campo de la psicología clínica o su defensa del terapeuta ecléctico, finalizando con algunos comentarios acerca de la eficacia de varias formas de psicoterapia.     

The Relationship Between Arousal and the Remembered Duration of Positive Events

The relation between affect and retrospective duration estimation has hardly been examined. In this paper, we contribute to filling this gap by studying the influence of arousal on the remembered duration of positive events. On the basis of the contextual change model, we expected that high‐arousal positive events would be remembered as longer compared with low‐arousal positive events. To test this hypothesis, we set up a naturalistic study in which participants were asked at the end of a pleasant amusement park ride at the local fair to rate how pleasant and aroused they felt during the ride as well as to estimate the ride's duration. Feeling more aroused during a ride was associated with longer estimates of the ride's duration. Results are discussed within the framework of retrospective time estimation models.
