How does our search engine “see” the world? The case of amodal completion

This article illustrates a dissociation between the perceived attributes of an object and the ability of those attributes to guide the deployment of attention in visual search. Orientation is an attribute that guides search. Thus, a vertical line will “pop out” amid horizontal distractors. Amodal completion can create perceptually convincing oriented stimuli when two elements appear to form a complete object partially hidden behind an occluder. Previous work (e.g., Rensink &; Enns, Vision Research, 38, 2489–2505, 1998) has shown a preattentive role for amodal completion in search tasks. Here, we show that orientation based on perceptually compelling amodal completion may fail to guide attention. The broader conclusion is that introspection is a poor guide to the capabilities of our internal search engine.     

Romantic relationship status biases memory of faces of attractive opposite-sex others: evidence from a reverse-correlation paradigm

Previous research has demonstrated that, presumably as a way to protect one’s current romantic relationship, individuals involved in a heterosexual romantic relationship tend to give lower attractiveness ratings to attractive opposite-sex others as compared to uninvolved individuals (i.e., the derogation effect). The present study importantly extends this research by examining whether romantic relationship status actually biases memory for the facial appearance of attractive (vs. unattractive) mates. To address this issue, we used a reverse-correlation technique (Mangini & Biederman, 2004), originally developed to get a visual approximation of an individual’s internal representation of a target category or person. In line with the derogation effect, results demonstrated that romantically involved (vs. uninvolved) individuals indeed held a less attractive memory of a previously encountered attractive mate’s face. Interestingly, they also held a more attractive memory of an unattractive mate’s face as compared to uninvolved individuals. This latter finding may suggest that romantically involved (as compared to uninvolved) individuals differentiate opposite-sex others along the attractiveness dimension less.     

Perceptual wholes can reduce the conscious accessibility of their parts

Humans can rapidly extract object and category information from an image despite surprising limitations in detecting changes to the individual parts of that image. In this article we provide evidence that the construction of a perceptual whole, or Gestalt, reduces awareness of changes to the parts of this object. This result suggests that the rapid extraction of a perceptual Gestalt, and the inaccessibility of the parts that make up that Gestalt, may in fact reflect two sides of the same coin whereby human vision provides only the most useful level of abstraction to conscious awareness.     

Type D assessment in patients with chronic heart failure and peripheral arterial disease: evaluation of the experimental DS(3) scale using item response theory

Type D personality refers to a clustering of 2 stable personality traits, namely negative affectivity and social inhibition. Currently Type D is standardly assessed using the DS14. An experimental Type D personality scale, the DS((3)), was developed to examine an avenue for assessing Type D more efficiently. The DS((3)) differs from the DS14 in its use of a 3-point Likert scale to rate responses, use of all negatively worded items, and a rearranged presentation of items. This article examines the psychometric properties of this questionnaire by examining its dimensionality, item and scale properties, and cutoff scores to screen for Type D personality. Data from 2 clinical samples were analyzed using item response theory. The results suggest that the DS((3)) is a potentially suitable instrument for Type D assessment. It has high reliability, and Type D personality classification based on this scale corresponds well with the current standard Type D assessment based on the DS14.     

Sport participation and stress among women and men

ObjectivesIn-depth analysis of the relationship between sports participation and stress among adult women and men.Design644 women and 783 men, 20–65 years, from the SPAH Flemish-Policy-Research-Centre, reported data on participation in favourite sports and mental health.MethodGender-specific multiple MANOVAs with stress appraisal and the stress response of emotional distress as dependent variables, and participation in 15 different types of sports as independent variables, including effect sizes (Cohen’s d) per sport-type.ResultsVery little difference in perceived-stress and emotional-distress existed in women and men who participated in different sport-types, suggesting that “one-activity-fits-all recommendations” are likely inappropriate. Different sports are suitable for different individuals, and it is important that one finds the sport that suits one best. Conversely, significant associations between participation in walking and in meditation sports manifested with both stress appraisal and emotional distress among women, and significant associations between participation in ball games and in water sports manifested with emotional distress among men.ConclusionsThe paper gathered substantial comprehensive insight and connected its quantitative data to existing qualitative data, presenting stimulating theoretical arguments. Sport-type related variations in the physical activity – mental health relationship were analyzed, based on the theory of mindful movement and the complexity paradigm identifying 3 coordinates on which the physical activity – mental health complexity unravels, based on: activity domains, mental health dimensions, and individual characteristics. The mindful movement theory proposes an underlying mechanism that could explain the positive physical activity – mental health relationship, and the complexity paradigm provides basis for creating a workable definition for ther concept of mindful physical activity.     

Search through complex motion displays does not break down under spatial memory load

Recent work has shown that observers are remarkably effective in searching displays of randomly moving items. In two experiments, we combined working memory tasks with visual search, to test whether search through such complex motion displays, as compared with search through static items, places an extra burden on spatial working memory. In our first experiment, we show that the dual-task interference observed for motion search is specific to spatial working memory, in line with earlier work for static search. In our second experiment, we found dual-task interference for both static and motion search, but no difference between them. The results support the suggestion that the same search process is active during search among static and search among moving items.     

A Review and Systematization of the Trolley Problem

The trolley problem, first described by Foot (1967) and Thomson (The Monist, 59, 204–217, 1976), is one of the most famous and influential thought experiments in deontological ethics. The general story is that a runaway trolley is threatening the lives of five people. Doing nothing will result in the death of those persons, but acting in order to save those persons would unavoidably result in the death of another, sixth person. It appears that, depending on the situation, we have different moral judgments about the permissibility of action. We will review and systematize all the proposals in the literature of the past 35 years that have attempted to grasp our moral intuitions in a simple deontological principle. In particular, seventeen proposals will be classified: six algorithmic, seven psychological, and four other invalid accounts. This review and classification sheds light on some subtle differences and clarify a few issues.     

An interactional approach to sexual dysfunctions

Abstract

This paper offers an interactional perspective as a broad and practical conceptual framework with which to understand patterns of sexual dysfunction. The theoretical model centers on the power of the sexual interaction as a critical focus for therapeutic change. The model is developed by presenting: the basic sexual interaction cycle, the individual and interactional variables that modify the sexual interaction cycle, and the creation of a continuously changing figure/ground configuration of sexual and nonsexual patterns. At various points in the discussion of the model, initial clinical strategies are derived to illustrate the applicability and advantages of an interactional perspective on sexual relationships.     

The form of the soul ― on the body in Freud’s psychoanalysis

To formulate the problem of the relation between body and soul in terms of how one should understand the relation between consciousness and the brain, or in terms of explaining how mind can arise out of matter, is a modern and far from innocent tendency that has instigated the whole spectrum of theories and answers suggested by the philosophy of mind of the so-called Analytic tradition during the 20th century. During the last 5 decades, we have seen a number of attempts at incorporating Freud into this discussion about the relation between body and soul. In this article, the author develops an argument according to which the philosophy of mind of the Analytic tradition is not really an appropriate intellectual environment for Freud´s theory of the body and its constitutive rôle. Rather, we should turn to phenomenology and transcendental philosophy where the body is thematized, not in terms of matter taken to give rise to consciousness in an empirical sense, but rather in terms of the “lived body” that is taken, in a transcendental sense, to constitute the organization of meaning in our conscious and our unconscious psychological life. On the basis of an outline of this phenomenological theory, the author argues that Freud, most of all in his theory of psychosexual development, thematizes the body as the form of the soul.
