Emerging Perspectives on Distinctions Between Romantic Love and Sexual Desire

Abstract— Although sexual desire and romantic love are often experienced in concert, they are fundamentally distinct subjective experiences with distinct neurobiological substrates. The basis for these distinctions is the evolutionary origin of each type of experience. The processes underlying sexual desire evolved in the context of sexual mating, whereas the processes underlying romantic love—or pair bonding—originally evolved in the context of infant-caregiver attachment. Consequently, not only can humans experience these feelings separately, but an individual's sexual predisposition for the same sex, the other sex, or both sexes may not circumscribe his or her capacity to fall in love with partners of either gender. Also, the role of oxytocin in both love and desire may contribute to the widely observed phenomenon that women report experiencing greater interconnections between love and desire than do men. Because most research on the neurobiological substrates of sexual desire and affectional bonding has been conducted with animals, a key priority for future research is systematic investigation of the coordinated biological, behavioral, cognitive, and emotional processes that shape experiences of love and desire in humans.     

Mindfulness meditation improves cognition: Evidence of brief mental training

Although research has found that long-term mindfulness meditation practice promotes executive functioning and the ability to sustain attention, the effects of brief mindfulness meditation training have not been fully explored. We examined whether brief meditation training affects cognition and mood when compared to an active control group. After four sessions of either meditation training or listening to a recorded book, participants with no prior meditation experience were assessed with measures of mood, verbal fluency, visual coding, and working memory. Both interventions were effective at improving mood but only brief meditation training reduced fatigue, anxiety, and increased mindfulness. Moreover, brief mindfulness training significantly improved visuo-spatial processing, working memory, and executive functioning. Our findings suggest that 4 days of meditation training can enhance the ability to sustain attention; benefits that have previously been reported with long-term meditators.     

Prenatal auditory experience and its sequelae

Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we present computational tests of the hypothesis that this early exposure to severely degraded auditory inputs serves an adaptive purpose—it may induce the neural development of extended temporal integration. Such integration can facilitate the detection of information carried by low-frequency variations in the auditory signal, including emotional or other prosodic content. To test this prediction, we characterized the impact of several training regimens, biomimetic and otherwise, on a computational model system trained and tested on the task of emotion recognition. We find that training with an auditory trajectory recapitulating that of a neurotypical infant in the pre-to-postnatal period results in temporally extended receptive field structures and yields the best subsequent accuracy and generalization performance on the task of emotion recognition. This strongly suggests that the progression from low-pass-filtered to full-frequency inputs is likely to be an adaptive feature of our development, conferring significant benefits to later auditory processing abilities relying on temporally extended analyses. Additionally, this finding can help explain some of the auditory impairments associated with preterm births, suggests guidelines for the design of auditory environments in neonatal care units, and points to enhanced training procedures for computational models.     

Symptom awareness and blood glucose estimation in diabetic adults

Self-regulation of diabetes depends in part on common-sense models of symptoms and blood glucose fluctuations. Symptom perception and subjective estimation of blood glucose were studied in 52 adult, difficult-to-control, non-insulin-dependent diabetics using a structured interview and laboratory blood-glucose measurement. Most patients believed they could detect hyperglycemia. Symptoms linked by patients to hyperglycemic and hypoglycemic episodes did overlap with symptoms traditionally associated with those states. Some patients may experience dysphoria during glycemic swings to which multiple symptom labels are applicable, although prominent exceptions and idiosyncratic symptoms were evident. Estimation of current blood glucose using an ordinal scale suggested some capacity for discriminating blood glucose levels. Numerical estimates of Chemstrip values were correlated with actual values, but far too inaccurately for purposes of self-regulation. Research is needed to clarify whether subjective symptom perception and blood glucose estimation helps or hinders self-regulation of diabetes.     

The Effect of Prior Fear Levels on UCS-expectancy Ratings to a Fear-relevant Stimulus

This study investigated the effect of levels of prior fear to a fear-relevant stimulus on UCS expectancy ratings in a threat conditioning procedure. The results suggested that UCS-expectancy ratings are independently influenced by both the nature of the stimulus (whether it is fear-relevant or fear-irrelevant) and the level of prior fear to the stimulus. Furthermore, significantly higher UCS-expectancy levels caused by prior fear and stimulus type were accompanied in some stages of the experiment by greater magnitudes of skin conductance responses during the stimulus.     

Using Interest Inventories as Interventions in Women's Career Development

Des changements importants se présentent dans la mesure des motivations professionnelles comme le résultat du mouvement féminin et des pressions pour minimiser le biais sexuel. Cet article démontre que la catégorisation des motivations peut servir soit comme moyen de maintenir le statu quo dans la distribution des professions féminines, soit comme agent catalytique pour ouvrir un champ plus large de choix de carrières traditionnelles ou non, aux hommes comme aux femmes. Une polémique à propos des changements psychométriques et l'efficacité de la catégorisation professionnelle est proposée, avec des recommandations pour l'utilisation des catégorisations comme des occasions d'augmenter les expériences exploratoires sur les professions et ainsi propulser le développement des carrières.
Marked changes have taken place in career interest measurement as a result of the women's movement and the pressures to minimise sex bias. This paper argues that interest inventories can serve either as devices to help maintain the status quo in the occupational distribution of women or as catalytic agents that can open up a wider spectrum of career options, traditional and non-traditional, to both women and men. Controversy regarding psychometric changes and the effectiveness of interest inventories is still an issue, but recommendations are offered for using interest inventories as interventions to increase exploratory occupational experiences and thus enhance career development.     

The Influence of Identity Salience on Framing Effectiveness: An Experiment

Efforts to influence attitudes on highly polarizing issues, such as climate change, often fail because individuals interpret political messages through the lens of their partisan identities. However, shifting the identity lens through which an individual interprets a message may result in more effective political communication. Through a preregistered survey experiment (n = 978), this study tested how priming either a partisan or a nonpartisan (parental) identity influenced the effectiveness of a climate change frame on several attitudinal outcomes. Findings suggest that identity salience—specifically partisan identity salience—can influence the effectiveness of a frame. Among Republican parents, receiving a message about the impact of climate change on future generations increased climate change concern and intended proclimate political behaviors, but this framing effect disappeared when a partisan identity was first primed. Among Democrat parents, framing had no significant effect until a partisan identity was first primed. The findings offer important insight into the role that identity salience plays in framing effectiveness and suggest that political communication on polarized issues is likely to be more effective at building bipartisan agreement when nonpartisan identities are salient.
