Media exposure, mood, and body image dissatisfaction: an experimental test of person versus product priming

In the current study, 138 college females were randomly assigned to four media exposure conditions based on the presence or absence of an attractive person (fashion model) and the presence or absence of an appearance-related product. Outcome measures consisted of visual analogue ratings of multiple body image and mood variables. The results revealed a significant main effect for person, indicating that the presence of a model increased levels of body dissatisfaction and negative mood. No product effect emerged and there was no significant interaction between person and product. These findings suggest that the appearance priming effect of media exposure on body dissatisfaction and mood is specific to a person stimulus, with no additional effect promoted by a generic appearance-relevant stimulus.     

Brief report: Teaching persons with moderate mental retardation to use printed instructions and time cues in a work context

Printed instructions and programable watches were used for helping two adults with moderate mental retardation perform variable tasks and follow a time schedule for task execution. The subjects, who could not read, were to match the words appearing in instruction notes to identical words superimposed on illustrative pictures (and collected in a vocabulary form). The pictures identified through this matching explained the meaning of the words being matched (i.e., indicated to the subjects which responses/tasks to perform). Self-recording was also used. The results showed that both subjects learned to use the printed instructions and the watches successfully. The subjects' performance remained positive over time. Procedural aspects and practical implications of the study are discussed.     

Locus of control and adjustment to cancer

The English form of the Cancer Locus of Control Scale was administered to an heterogeneous sample of 68 cancer patients. A principal components analysis confirmed the three subscales described in the original Dutch form, however, with five items excluded. Correlations with other measures indicated that high internal control over the course of the illness was associated with a tendency to adopt an attitude toward cancer of 'fighting spirit' whereas high internal control over the cause of the illness was associated with an 'anxious preoccupation' about cancer. No specific relationship was found between scale scores and either depression and anxiety or the tendency to be emotionally controlled. It was concluded that the scale provides a valid measure of perceptions of control of cancer patients and is a useful method of assessing these important psychological responses.     

“Out of disegno invention is born” — Drawing a convincing figure in Renaissance Italian Art

An important artistic topic of Italian Renaissance painting was the rendering of the human figure. As leading actors in a painted narrative, figures had to convince beholders of the reality of the matter depicted with appropriated attitudes and gestures. This article is about two ways of drawing or rather constructing the human figure artists developed to achieve this goal. The first was only an adaptation to an old method: because of the rather simple and coarse elements used, constructions often resulted in faulty pictures and were for that matter often criticized. As this article will show, the second method involved a new and very successful drawing skill, which not just required a different kind of knowledge of visual forms but of procedures of moving the hand, too.This article is a summary of the central thesis of my dissertationSporen van vaardigheid. De ontwerpmethode voor de figuurhouding in de Italiaanse tekenkunst van de renaissance, Abcoude 1991, which was published only in Dutch. I would like to thank A.Gasten for her help in translating the text of this article.     

On historicity,context and the existence of African philosophy

Abstract

The author reviews the second edition of Philosophy from Africa by comparing it with the first edition and with other anthologies in African philosophy. Questions regarding the existence and identity of African philosophy receive special attention. It is argued that a negation of the existence of African philosophy results from monolithic, ahistorical and decontextualized thinking about Africa and about philosophy. The roots and development of African philosophy are inseparably bound up with the continent’s historical, political, cultural and economic complexities. The challenge facing African philosophers is twofold: deconstructing the notion of philosophy as constructed and conceived by the West; and reconstructing the history of African philosophy.     

The effect of fMRI (noise) on cognitive control

Stressful situations, the aversiveness of events, or increases in task difficulty (e.g., conflict) have repeatedly been shown to be capable of triggering attentional control adjustments. In the present study we tested whether the particularity of an fMRI testing environment (i.e., EPI noise) might result in such increases of the cognitive control exerted. We found that participants were more effective in controlling episodic retrieval of previous stimulus-response bindings (Experiment 1), in switching to a new task (Experiment 2), and shielding a current goal from distracting response tendencies (Experiment 3) if they were exposed to challenging task situations, such as 70 dB echo planar imaging noise sampled from an fMRI scanner. These findings have considerable theoretical implications in questioning the widespread assumption that people are equally devoted to easy and more challenging tasks, and methodological implications in raising the possibility that experiments carried out in fMRI scanners or under otherwise challenging conditions systematically overestimate contributions from cognitive control processes.     

This is funny: on the beneficial role of self-enhancing and affiliative humour in job design

Building on positive psychology, the present study aims to address the role of humour in the workplace, and particularly in job design, one of the crucial job aspects contributing to employee well-being. Specifically, we examine the main effects of self-enhancing and affiliative types of humour both on burnout and work engagement. Furthermore, we study whether these humour styles serve as personal resources, moderating the associations of job hindrances (i.e., role conflict), job challenges (i.e., workload) and job resources (i.e., social support) with burnout and work engagement, as outlined in the Job Demands-Resources model. Results in a large sample of Belgian employees ( N = 1200) showed that both types of humour related negatively to burnout and positively to work engagement. No interactions between humour and the job characteristics were found in the prediction of burnout. The significant interactions in predicting work engagement showed that self-enhancing and affiliative humour played a positive role, particularly when role conflict and social support were low. No interactions with workload were found. The discussion aims to shed light on the unexpected results and to further the study of the humour-health hypothesis.     

Engineering and the Problem of Moral Overload

When thinking about ethics, technology is often only mentioned as the source of our problems, not as a potential solution to our moral dilemmas. When thinking about technology, ethics is often only mentioned as a constraint on developments, not as a source and spring of innovation. In this paper, we argue that ethics can be the source of technological development rather than just a constraint and technological progress can create moral progress rather than just moral problems. We show this by an analysis of how technology can contribute to the solution of so-called moral overload or moral dilemmas. Such dilemmas typically create a moral residue that is the basis of a second-order principle that tells us to reshape the world so that we can meet all our moral obligations. We can do so, among other things, through guided technological innovation.     

Visuospatial perceptual sequence learning and eye movements

We examined perceptual sequence learning by means of an adapted serial reaction time task in which eye movements were unnecessary for performing the sequence learning task. Participants had to respond to the identity of a target letter pair ("OX" or "XO") appearing in one of four locations. On the other locations, similar distractor letter pairs ("QY" or "YQ") were shown. While target identity changed randomly, target location was structured according to a deterministic sequence. To render eye movements superfluous, (1) stimulus letter pairs appeared around a fixation cross with a visual angle of 0.63°, which means that they appeared within the foveal visual area and (2) the letter pairs were presented for only 100 ms, a period too short to allow proper eye movements. Reliable sequence knowledge was acquired under these conditions, as responses were both slower and less accurate when the trained sequence was replaced by an untrained sequence. These results support the notion that perceptual sequence learning can be based on shifts of attention without overt oculomotor movements.
