Deliberating in the presence of manipulation

According to deliberation compatibilism, rational deliberation is compatible with the belief that one’s actions are causally determined by factors beyond one’s control. This paper offers a counterexample to recent accounts of rational deliberation that entail deliberation compatibilism. The counterexample involves a deliberator who believes that whichever action she performs will be the result of deterministic manipulation. It is further argued that there is no relevant difference between the purported counterexample and ordinary doxastic circumstances in which a determinist deliberates.     

Healing presence in the psychotherapist

Abstract

Throughout graduate school I felt compelled to become a fine psychotherapist. Implicit in that motivation was my curiosity about what makes a psychotherapist effective. My curiosity was inspired by my experience with one therapist who helped me activate profound transformation. After identifying intuitive inquiry (Anderson, 1998, 2000, 2004) as my research method, I explored that experience through meditation, reading, and conversation and eventually identified her healing presence as the core quality that differentiated her from other therapists I had known. Though technique and experience are important, I sensed that it was her healing presence that allowed her to use technique and experience skillfully. Throughout Cycle 1 of intuitive inquiry, the “text” that claimed me was my personal experience of her healing presence, her ability to be present, to connect with me, to see me, and even, to love me. Through intuitive inquiry, I was able to expand my understanding of the healing presence of a psychotherapist to incorporate the experiences of many others.     

Reafference learning in the presence of exafference

Reafference learning has been demonstrated most clearly in the case of position-constancy adaptation in which the only stimulus change is caused by the subject’s own movoment. The present study used the more ecologically representative training situation in which only part of the stimulus change is caused by the subject (reafference), while part of it is caused by an independent source (exafference). The exafference varied the space relation between subject movement and optical movement or the time relation between those two. In both cases, reafference learning was not affected by the exafference, and the subject’s varied training experience resulted in a fixed expected optical movement and a fixed expected time lag.     

On presence in the psychoanalytic relation

This paper discusses presence in the psychoanalytic relation, the analysand’s and the analyst’s. Clinical situations with different qualities of presence will be considered focusing on what kind of interplay between analysand and analyst they may lead to. As examples, I have chosen three different clinical situations: In the first there is an interplay between the analysand’s free associations and the analyst’s ‘evenly suspended attention’. In connection with this I will discuss Bion’s concepts of ‘reverie’ and of ‘O’. In the second there is where the interaction is characterised by what Meltzer calls ‘geographical confusion’. In the third there is a ‘transference delusion’ in the psychoanalysis of breakdown as Winnicott describes it.     

How the presence of persons biases eye movements

We investigated modulation of gaze behavior of observers viewing complex scenes that included a person. To assess spontaneous orientation-following, and in contrast to earlier studies, we did not make the person salient via instruction or low-level saliency. Still, objects that were referred to by the orientation of the person were visited earlier, more often, and longer than when they were not referred to. Analysis of fixation sequences showed that the number of saccades to the cued and uncued objects differed only for saccades that started from the head region, but not for saccades starting from a control object or from a body region. We therefore argue that viewing a person leads to an increase in spontaneous following of the person’s viewing direction even when the person plays no role in scene understanding and is not made prominent.     

Lightness constancy in the presence of specular highlights

Abstract— Visible surfaces in a natural environment often have multiple components of reflectance, including a diffuse component, by which light is scattered isotropically in all possible directions, and a specular component, by which light is reflected anisotropically within a limited range of directions. The research described in the present article was designed to investigate how these different components of reflectance influence the perception of lightness. Human observers were presented with shaded images of smoothly curved surfaces and asked to compare the relative lightness of different surface regions whose diffuse and specular components of luminance were independently manipulated. The results revealed that observers are able to discount the presence of specular highlights so that the relative lightness among different regions is determined almost entirely by the diffuse component of surface reflectance.     

Sensing the presence of the deceased: A narrative review

Researchers have reported that bereaved people often continue to sense the presence of the deceased. A particular collection of such experiences can be identified as instilling a perception that the deceased person is in some manner present in the company of the bereaved person. The aim of the current review was to synthesise the results on this topic to provide a comprehensive over-view for practitioners working with bereaved people who report these experiences. The studies were reviewed in terms of the nature of the experiences described, the provision of explanatory models to understand the significance of these experiences, describing any culturally specific aspects of these experiences, discussion of the personal impact of having the experiences, and for recommendations of how people who have these experiences can be supported.     

Immersion and the illusion of presence in virtual reality

This commentary briefly reviews the history of virtual reality and its use for psychology research, and clarifies the concepts of immersion and the illusion of presence.     

Detecting the presence of a singleton involves focal attention

It has been claimed that the detection of a feature singleton can be based on activity in a feature map that allows coarse coding that something unique is present in the visual field. In the present study, participants detected the presence or absence of a color singleton. Even though the letter form of the color singleton was task-irrelevant, we showed that repeating the letter form of the singleton resulted in repetition priming on the next trial. Such repetition priming was not found when a nonsingleton letter was repeated as the singleton. Since the letter form of the color singleton could only be picked up by focal attention, the repetition priming effect indicates that focal attention is allocated to the feature singleton even in the simplest present-absent feature detection tasks. We showed that this effect is equally strong in conditions of low and high perceptual load. These results are inconsistent with theories that it is possible to detect a feature singleton without directing some form of attention to its location.     

Clustering binary data in the presence of masking variables

A number of important applications require the clustering of binary data sets. Traditional nonhierarchical cluster analysis techniques, such as the popular K-means algorithm, can often be successfully applied to these data sets. However, the presence of masking variables in a data set can impede the ability of the K-means algorithm to recover the true cluster structure. The author presents a heuristic procedure that selects an appropriate subset from among the set of all candidate clustering variables. Specifically, this procedure attempts to select only those variables that contribute to the definition of true cluster structure while eliminating variables that can hide (or mask) that true structure. Experimental testing of the proposed variable-selection procedure reveals that it is extremely successful at accomplishing this goal.     

Modeling competence development in the presence of selection bias

A major challenge for representative longitudinal studies is panel attrition, because some respondents refuse to continue participating across all measurement waves. Depending on the nature of this selection process, statistical inferences based on the observed sample can be biased. Therefore, statistical analyses need to consider a missing-data mechanism. Because each missing-data model hinges on frequently untestable assumptions, sensitivity analyses are indispensable to gauging the robustness of statistical inferences. This article highlights contemporary approaches for applied researchers to acknowledge missing data in longitudinal, multilevel modeling and shows how sensitivity analyses can guide their interpretation. Using a representative sample of N = 13,417 German students, the development of mathematical competence across three years was examined by contrasting seven missing-data models, including listwise deletion, full-information maximum likelihood estimation, inverse probability weighting, multiple imputation, selection models, and pattern mixture models. These analyses identified strong selection effects related to various individual and context factors. Comparative analyses revealed that inverse probability weighting performed rather poorly in growth curve modeling. Moreover, school-specific effects should be acknowledged in missing-data models for educational data. Finally, we demonstrated how sensitivity analyses can be used to gauge the robustness of the identified effects.     

Enactivism and the “problem” of perceptual presence

One of the classic debates in cognitive science is between nativism and empiricism about the development of psychological capacities. In principle, the debate is empirical. However, in practice nativist hypotheses have also been challenged for relying on an ill-defined, or even unscientific, notion of innateness as that which is “not learned”. Here this minimal conception of innateness is defended on four fronts. First, it is argued that the minimal conception is crucial to understanding the nativism-empiricism debate, when properly construed; Second, various objections to the minimal conception—that it risks overgeneralization, lacks an account of learning, frustrates genuine explanations of psychological development, and fails to unify different notions of innateness across the sciences—are rebutted. Third, it is argued that the minimal conception avoids the shortcomings of primitivism, the prominent view that innate capacities are those that are not acquired via a psychological process in development. And fourth, the minimal conception undermines some attempts to identify innateness with a natural kind. So in short, we have little reason to reject, and good reason to accept, the minimal conception of innateness in cognitive science.
