An after-effect in haptic space perception

After-effects in haptic perception have been little studied. But they seem to be prominent, and easy to elicit. An after-effect of the perception of the vergence of two surfaces is described, and is shown to be independent of the slant of the surfaces. It is not “figural.” Spatial perception with the hands, as well as with the eyes, is apparently based on a fluid and adaptable receptive system.     

A VERSATILE EYE-MOVEMENT RECORDER

A small, light eye-movement recorder, capable of registering eye movements from the smallest voluntary movements to movements of 20 degrees of arc, is described. A miniature light projector gives a beam of infrared (or blue) light, which is reflected by the cornea of the eye. The beam is deflected by any movement of the eye. An optical system transforms the motion of the beam into changes of light intensity. These are translated into magnified fluctuations of current in a multiplier phototube. The output is translated into graphic form by an ink-writer fitted with a D.C. amplifier. The apparatus, except for the writer but including a helmet, weighs about 300–500 g and is mounted on the subject's head without appreciably disturbing the field of vision.     

What is an organ? Heidegger and the phenomenology of organ transplantation

This paper investigates the question of what an organ is from a phenomenological perspective. Proceeding from the phenomenology of being-in-the-world developed by Heidegger in Being and Time and subsequent works, it compares the being of the organ with the being of the tool. It attempts to display similarities and differences between the embodied nature of the organs and the way tools of the world are handled. It explicates the way tools belong to the totalities of things of the world that are ready to use and the way organs belong to the totality of a bodily being able to be in this very world. In so doing, the paper argues that while the organ is in some respects similar to a bodily tool, this tool is nonetheless different from the tools of the world in being tied to the organism as a whole, which offers the founding ground of the being of the person. However, from a phenomenological point of view, the line between organs and tools cannot simply be drawn by determining what is inside and outside the physiological borders of the organism. We have, from the beginning of history, integrated technological devices (tools) in our being-in-the-world in ways that make them parts of ourselves rather than parts of the world (more organ- than tool-like), and also, more recently, have started to make our organs more tool-like by visualising, moving, manipulating, and controlling them through medical technology. In this paper, Heidegger’s analysis of organ, tool, and world-making is confronted with this development brought about by contemporary medical technology. It is argued that this development has, to a large extent, changed the phenomenology of the organ in making our bodies more similar to machines with parts that have certain functions and that can be exchanged. This development harbours the threat of instrumentalising our bodily being but also the possibility of curing or alleviating suffering brought about by diseases which disturb and destroy the normal functioning of our organs.     

State Perfectionism and its Relation to Trait Perfectionism,Type of Situation,Priming, and Being Observed

Perfectionism is normally viewed as a multidimensional personality trait. In the present experimental study, perfectionism was treated as a state in which transient changes were produced through manipulation of 2 factors: being observed by others and verbal priming. The experiment was carried out in 2 different situations: a social encounter situation and a problem-solving situation. Partial support for the hypothesis that both priming and observation cause elevated degrees of perfectionism was found in the social encounter situation. In the problem-solving situation, observation produced some effects, although partly in an unexpected direction. A significant interaction effect between priming and observation was found on estimating performance on a memory task in the problem-solving situation. The state approach to perfectionism and the stability of perfectionism across situations are discussed on the basis of the findings.     

Freud's philosophy of the uncanny

This paper is an attempt to uncover and bring to a coherent interpretation Freud's thoughts on the phenomenon of uncanniness. Starting out with the essay “The uncanny” the author wants to show that uncanniness plays an important rôle in the turn that Freud's thinking goes through at this time, and that the concept can serve as a springboard for a critical, phenomeno- logical reading of Freud's thoughts on the development of the ego. The analysis of the phenomenon of uncanniness itself tends to disrupt the coherence of Freud's earlier views and pushes him towards his later thinking. “Unheimlich” in German has the double meaning of uncanny and unhome-like, and what is not at home in itself in an uncanny sense, according to Freud, is precisely the human ego. Freud in “The uncanny” links the interpretation of uncanniness to compulsive repetition and thus makes the connection to trauma and birth anxiety discussed in later works such as “Beyond the pleasure principle” and “Inhibitions, symptoms and anxiety”. The origin of our general sensitivity to the uncanny is thus, according to Freud, the loss of the mother suffered by the child as a kind of a priori traumatic experience, which is also the very event that makes the child into an ego. The understanding of traumatic neurosis and other forms of mental illness is consequently linked to an analysis of this primal uncanniness of life.     

Stigmatization and Male Identity: Norwegian Males’ Experience after Identification as BRCA1/2 Mutation Carriers

In families with hereditary breast and ovarian cancer, there is limited knowledge about the reactions of BRCA1/2 mutation positive males. In the present qualitative study, fifteen BRCA1/2 mutation positive men in Norway participated in two successive, in-depth interviews. Seven female partners participated in the second interview. The men reported strong emotional reactions to their positive test results, and they expressed a desire to keep the genetic information private. They considered discussing their test results or health related information with other males as difficult, and they perceived females as their sources of social and emotional support. Interestingly, the second interview revealed important information not communicated during the first interview. The findings of this study contribute to the discussion of whether men who test positive for a BRCA1/2 mutation should receive tailored genetic counseling sessions. Health care providers should be aware of psychological vulnerability in these men, likely stemming from fewer emotional supports in their social networks.     

Will I Fit in and Do Well? The Importance of Social Belongingness and Self-Efficacy for Explaining Gender Differences in Interest in STEM and HEED Majors

Throughout the world, the labor market is clearly gender segregated. More research is needed to explain women’s lower interest in STEM (Science, Technology, Engineering and Mathematics) majors and particularly to explain men’s lower interest in HEED (Health care, Elementary Education, and the Domestic spheres) majors. We tested self-efficacy (competence beliefs) and social belongingness expectations (fitting in socially) as mediators of gender differences in interest in STEM and HEED majors in a representative sample of 1327 Swedish high school students. Gender differences in interest in STEM majors strongly related to women’s lower self-efficacy for STEM careers and, to a lesser degree, to women’s lower social belongingness expectations with students in STEM majors. Social belongingness expectations also partly explained men’s lower interest in HEED majors, but self-efficacy was not an important mediator of gender differences in interest in HEED. These results imply that interventions designed to lessen gender segregation in the labor market need to focus more on the social belongingness of students in the gender minority. Further, to specifically increase women’s interest in STEM majors, we need to counteract gender stereotypical competence beliefs and assure women that they have what it takes to handle STEM careers.     

Emotion processing facilitates working memory performance

The effect of emotional stimulus content on working memory performance has been investigated with conflicting results, as both emotion-dependent facilitation and impairments are reported in the literature. To clarify this issue, 52 adult participants performed a modified visual 2-back task with highly arousing positive stimuli (sexual scenes), highly arousing negative stimuli (violent death) and low-arousal neutral stimuli. Emotional stimulus processing was found to facilitate task performance relative to that of neutral stimuli, both in regards to response accuracy and reaction times. No emotion-dependent differences in false-alarm rates were found. These results indicate that emotional information can have a facilitating effect on working memory maintenance and processing of information.
