Hypervigilance in patients with borderline personality disorder: specificity, automaticity, and predictors

According to cognitive theory, an important factor in borderline personality disorder (BPD) is hypervigilance. The aim of the present study was to test whether BPD patients show schema-related biases, and to explore relations with childhood trauma, schemas, and BPD symptoms. Sixteen BPD patients were compared with 18 patients with a cluster C personality disorder, 16 patients with an axis I disorder, and 16 normal controls. An emotional Stroop task was applied with schema-related and unrelated, negative and positive, supra- and subliminal person-related stimuli. BPD patients showed hypervigilance for both negative and positive cues, but were specifically biased towards schema-related negative cues. Predictors were BPD schemas, childhood sexual traumas, and BPD anxiety symptoms. Both BPD and axis I disorder patients showed a trend for a bias for negative schema-related subliminal stimuli. More attention to hypervigilance in BPD is recommended for clinical practice.     

Explaining sex differences in infants' preferences for groups

Social organization of a species influences myriad facets of individuals’ behavior. Much research indicates that human social organization consists of males in large groups and females in smaller groups or interacting with individuals. This study analyzed the initial factors that produce greater preferences for groups by human male versus female infants. To this end, using a looking preference paradigm, fifty-nine 6–8-month-old infants viewed individual versus group images of actual children. On the basis of several controls, results demonstrated that male more than female infants are attracted to the complex level of stimulation provided by groups. Discussion centers on further identifying male versus female patterns of group interaction from a perceptual and cognitive standpoint.     

Perceptual latency priming: A measure of attentional facilitation

The present paper reviews recent research on perceptual latency priming (PLP). PLP is the relative latency advantage-earlier perception-of a visual stimulus that is preceded by another, masked stimulus at its location. The first stimulus attracts attention which accelerates perception of the second stimulus. This facilitation arises even if the first stimulus is visually backward-masked by the second one. The paper summarises research on temporal and spatial properties of PLP and the question whether intentions mediate shifts of attention to external events. Possible sources of PLP besides visuo-spatial attention are discussed. Finally, I give a review of feedforward and reentrant models of PLP and compare them to the empirical evidence.     

Indecent Exposure: Self-objectification and Young Women’s Attitudes Toward Breastfeeding

The sexualization of the breast may lead women who internalize the sexual objectification of their bodies to have more negative attitudes toward breastfeeding. The purpose of the present study was to examine self-objectification in relation to young women’s attitudes toward and concerns about breastfeeding. Two hundred and seventy-five female undergraduates completed a survey with questions that assessed their plans for infant feeding, attitudes toward breastfeeding, concerns about breastfeeding, and self-objectification. Women who scored higher on measures of self-objectification were more likely to view public breastfeeding as indecent and to be concerned that breastfeeding would be embarrassing and would negatively impact their bodies and sexuality. Self-objectification was not related to general attitudes toward breastfeeding or to young women’s future infant feeding plans. Implications for theory and future research are discussed. An earlier version of this study was presented at the annual meeting of the American Psychological Association, Washington, DC (August, 2005).     

Memory trace stabilization leads to large-scale changes in the retrieval network: a functional MRI study on associative memory

Spaced learning with time to consolidate leads to more stabile memory traces. However, little is known about the neural correlates of trace stabilization, especially in humans. The present fMRI study contrasted retrieval activity of two well-learned sets of face-location associations, one learned in a massed style and tested on the day of learning (i.e., labile condition) and another learned in a spaced scheme over the course of one week (i.e., stabilized condition). Both sets of associations were retrieved equally well, but the retrieval of stabilized association was faster and accompanied by large-scale changes in the network supporting retrieval. Cued recall of stabilized as compared with labile associations was accompanied by increased activity in the precuneus, the ventromedial prefrontal cortex, the bilateral temporal pole, and left temporo–parietal junction. Conversely, memory representational areas such as the fusiform gyrus for faces and the posterior parietal cortex for locations did not change their activity with stabilization. The changes in activation in the precuneus, which also showed increased connectivity with the fusiform area, are likely to be related to the spatial nature of our task. The activation increase in the ventromedial prefrontal cortex, on the other hand, might reflect a general function in stabilized memory retrieval. This area might succeed the hippocampus in linking distributed neocortical representations.     

Disgust and psychopathological symptoms in a nonclinical sample

There is little doubt that disgust sensitivity plays a role in the development of small animal phobias. However, it has been suggested that the basic emotion of disgust is implied in a broad range of psychopathological conditions. The present study examined the relationship between disgust sensitivity and symptoms of phobias (other than animal phobias), obsessive–compulsive disorder, depression, and eating disorder in a nonclinical sample. Undergraduate psychology students were asked to complete the Disgust Sensitivity Questionnaire, as well as measures of phobic (Fear Questionnaire), obsessive–compulsive (Maudsley Obsessive–Compulsive Inventory), depressive (Beck Depression Inventory), and eating disorder (Restraint Scale) symptomatology. Results showed that disgust sensitivity was only related to symptoms of agoraphobia and obsessive–compulsive disorder. The present findings cast doubts on the idea that disgust sensitivity is a central factor underlying a broad range of psychopathological conditions.     

How the sperm dominates the ovum — objectification by metaphor in the social representation of conception

This investigation is about the use of metaphors in the everyday understanding of conception. It is argued that the analysis of the relationship between source and target domain in a metaphor used as an objectification device can help explain how social representations are acquired collectively and individually. We expect that in popular knowledge of conception the central metaphors and images relate to the subjects' everyday experience as social actors and sexual beings because social and sexual experience is pervasive and well-understood. In an experimental questionnaire study involving 169 subjects, it is shown as hypothesized that subjects prefer to compare the process of fertilization, i.e. the role and behaviour of sperms and ovum, with sexual and sex-role behaviour where the role of men is projected upon sperms and the role of women upon the ovum. This implies that sperms are seen not only as more active, but also as harder, stronger, and more dominant than the ovum. These effects are stronger, the more subjects personally subscribe to a more conservative sex-role orientation. In the discussion it is suggested that it is necessary to analyse the two intricately linked levels of objectification, the cognitive process of selecting specific images and the social process of the diffusion of popular knowledge, if we want to understand how common sense works.     

Evidence against response bias in temporal order tasks with attention manipulation by masked primes

Attending to a location shortens the perceptual latency of stimuli appearing at this location (perceptual latency priming). According to attentional explanations, perceptual latency priming relies on the speeded transfer of attended visual information into an internal model. However, doubts about the attentional origin have repeatedly been raised because efforts to minimize response bias have been insufficient in most studies. Five experiments investigated the contribution of a response bias to perceptual latency priming (judgment bias due to the two-alternative forced-choice method and due to the existence of the prime, criterion effects or second-order bias, sensorimotor priming). If any, only small response biases were found. The results thus support the attentional explanation.
