Behavioral and neural correlates of disrupted orienting attention in posttraumatic stress disorder

Prior work has revealed that posttraumatic stress disorder (PTSD) is associated with altered (a) attentional performance and (b) resting-state functional connectivity (rsFC) in brain networks linked to attention. Here, we sought to characterize and link these behavioral and brain-based alterations in the context of Posner and Peterson’s tripartite model of attention. Male military veterans with PTSD (N = 49; all deployed to Iraq or Afghanistan) and healthy age-and-gender-matched community controls (N = 26) completed the Attention Network Task. A subset of these individuals (36 PTSD and 21 controls) also underwent functional magnetic resonance imaging (fMRI) to assess rsFC. The behavioral measures revealed that the PTSD group was impaired at disengaging spatial attention, relative to the control group. FMRI measures further revealed that, relative to the control group, the PTSD group exhibited greater rsFC between the salience network and (a) the default mode network, (b) the dorsal attention network, and (c) the ventral attention network. Moreover, problems with disengaging spatial attention increased the rsFC between the networks above in the control group, but not in the PTSD group. The present findings link PTSD to both altered orienting of spatial attention and altered relationships between spatial orienting and functional connectivity involving the salience network. Interventions that target orienting and disengaging spatial attention may be a new avenue for PTSD research.     

Neural circuitry of emotion regulation: Effects of appraisal,attention, and cortisol administration

Psychosocial well-being requires effective regulation of emotional responding in context of threat or stress. Neuroimaging studies have focused on instructed, volitional regulation (e.g., reappraisal or distancing), largely ignoring implicit regulation that does not involve purposeful effort to alter emotional experience. These implicit processes may or may not involve the same neural pathways as explicit regulatory strategies. We examined the neurobiology of implicit emotional regulation processes and the impact of the stress hormone cortisol on these processes. Our study task employed composite pictures of faces and places to examine neural activity during implicit emotional processing (of emotional faces), while these responses were implicitly regulated by attention shift away from the emotionally evocative stimuli, and while subjects reflectively appraised their own emotional response to them. Subjects completed the task in an fMRI scanner after random assignment to receive placebo or hydrocortisone (HCT), an orally administered version of cortisol. Implicit emotional processing activated insula/IFG, dACC/dMPFC, midbrain and amygdala. With attention shifting, we saw diminished signal in emotion generating/response regions (e.g., amygdala) and increased activations in task specific attention regions like parahippocampus. With appraisal of emotions, we observed robust activations in medial prefrontal areas, where activation is also seen in instructed reappraisal studies. We observed no main effects of HCT administration on brain, but males and females showed opposing neural effects in prefrontal areas. The data suggest that different types of emotion regulation utilize overlapping circuits, but with some strategy specific activation. Further study of the dimorphic sex response to cortisol is needed.     

Repairing links: building attachments in the preschool classroom

A psychoanalytic model of preschool consultation is presented, born of the conviction that psychoanalysis has powerful tools with which to tackle some of our most difficult and entrenched community problems. Since trauma is known to impact our ability to think reflectively and symbolically (Fonagy, Moran, and Target 1993), the clinical methods of psychoanalysis-drawing on the ideas of container/contained, the capacity to hold alternate points of view, and the capacity to reflect empathically (here with teachers in the face of their at times harsh and insensitive treatment of students)-are crucial to success in work with cumulatively traumatized staff (Khan 1963). The strongest resistances to consultation arise from an anti-attachment system developed as a result of cumulative trauma and operating at multiple levels in the preschool. Consultation services are organized around an understanding of this anti-attachment system. At various levels of the system, including staff, parents, and children, consultants work to facilitate secure relationships in the preschool setting. These relationships foster recognition of children's emotional complexities and build cooperative links between staff and parents, in an atmosphere that otherwise might often push adults into fearful, self-protective states that interfere with their contact with children's states of mind.     

Implicit motives and sexual conservatism as predictors of sexual behaviors

This study was designed to provide an assessment of the relationship between the two most important implicit motives and the most frequently studied sexual behaviors. A community sample of 102 men and 92 women completed measures of implicit power and affiliation-intimacy motives, sexual conservatism, social desirability, and sexual behavior. For men, high power motivation was positively associated with the number of sexual partners and the frequency of sex. There was an interaction between sexual conservatism and power motivation in women. For women low in sexual conservatism, high power motivation was positively associated with the number of sexual partners and with earlier initiation to intercourse and oral sex. There were few associations between affiliation-intimacy motivation and sexual behaviors; however, women high in this motive reported later initiation to oral sex.     

The push and pull of temptation: the bidirectional influence of temptation on self-control

This article examines how people respond to the emergence of temptation in their environment. Three studies demonstrated that how people respond to temptation depends critically on their visceral state--whether or not they are actively experiencing visceral drives such as hunger, drug craving, or sexual arousal. We found that when people were in a "cold," nonvisceral state, the presence of temptation prompted cognition to support self-control. However, when people were in a "hot," visceral state, temptation prompted the same cognitive processes to support impulsive behavior. Study 1 examined how heterosexual men's level of sexual arousal influences their attention to attractive women. Study 2 examined whether satiated and craving smokers would engage in motivated reasoning in order to dampen (or enhance) the appeal of smoking when confronted with the temptation to smoke. Study 3 tested the boundaries of the interaction between visceral state and temptation.     

Reactivity to Stress: When Does a History of Medical Adversity Foster Resilience Versus Vulnerability?

Young adults with (or without) a history of medical or physical disorders (MPDs) were exposed to repeated laboratory stress. The effects of MPD status on habituation (as measured by changing levels of cortisol) were found to be moderated by the extent to which respondents reported “attachment feelings” in their relationships (as measured by the Social Provisions Scale). Students in the MPD group who reported attachment feelings showed (a) cortisol increases during their first exposure to a laboratory stressor; and (b) cortisol decreases during a second exposure to the same stressor 1 week later. No equivalent benefit was found for students who lacked this medical history. Findings suggest the extent to which medical adversity—under the right interpersonal circumstances—promotes resilience.     

Who Wants to Marry a Millionaire? Reality Dating Television Programs, Attitudes Toward Sex, and Sexual Behaviors

Past research has revealed associations between television viewing and sexual attitudes and behaviors. We examined a burgeoning new television genre, reality dating programs (RDPs). Undergraduate students (ages 18–24) reported their overall television viewing, their RDP viewing, and their involvement with RDPs (watching in order to learn and watching in order to be entertained). They also completed measures of attitudes toward sex, dating, and relationships, and answered questions about sexual behavior. Most participants were occasional or frequent viewers of at least one RDP. Men reported using RDPs for learning more than did women; there was no gender difference in use of RDPs for entertainment. Total amount of RDP viewing was positively correlated, for both men and women, with adversarial sexual beliefs, endorsement of a sexual double standard, and the beliefs that men are sex-driven, that appearance is important in dating, and that dating is a game. In all cases, however, these relationships were partially or totally mediated through viewer involvement. Men and women who watched RDPs tended to be less sexually experienced; there were few other correlations with sexual behaviors.     

Pentecostal Dynamics of African Initiated Churches

This essay is a historical consideration of the body of churches known as African Initiated Churches (AICs). The key research questions I am investigating are whether this church can be classified as Pentecostal and how it employs transnational networking in its mission strategy. I have approached this question by exploring the Pentecostal dynamics and transnational networking of the Cherubim and Seraphim Church as an example of an AIC. To this end, I analyze the Pentecostal and transnational nature of an international ecumenical conference organized by the church in London in 2017. This essay is written from the perspective of someone who was born and raised within the church movement, but has also studied the movement as part of African Christianity. The originality of this essay is in its analysis of the transnational nature of the international ecumenical conference.     

Real Men Get the Best Bar Girls: Performing Masculinities in China’s Global Sex Industry

The shifting power relations in China after the global financial crisis are redefining masculinity for both Western and Asian men. Connell (1995) argues that in most societies a hegemonic masculinity usually exists that privileges heterosexual middle-class and economically successful men who exhibit characteristics associated with being masculine. The global financial crisis has led to a new global financial order that has created paths for people to reimagine hierarchies of class, gender, nation, race, and sexuality. “Entangled masculinities” recognizes that the intersections of class, gender, nation, race, and sexuality shape identities of male clients who buy commercial sex. The article looks specifically at clients from three niche commercial sex markets (low, mid, and high tier) in Dongguan, China. Specifically, five patterns of behavior exhibited by male clients to rationalize and assert their masculinity will be analyzed in depth: vigorous and macho; austere and essentialist; suppressive and anxious; extravagant and competitive; and refined and collaborative. This article argues clients with vigorous and macho, austere and essentialist, and suppressive and anxious behavior types are frequently found in low-end and mid-tier bars. Patrons of higher-tier bars tended to engage in extravagant and competitive and refined and collaborative behavior through expressions of wealth and power.     

Psychometric evaluation of the Multidimensional Assessment of Fatigue scale for use with pregnant and postpartum women

Although fatigue is a common experience for pregnant women and new mothers, few measures of fatigue have been validated for use with this population. To address this gap, the authors assessed psychometric properties of the Multidimensional Assessment of Fatigue (MAF) scale, which was used in 2 independent samples of pregnant women. Results indicated that the psychometric properties of the scale were very similar across samples and time points. The scale possesses a high level of internal consistency, has good convergent validity with measures of sleep quality and depression, and discriminates well from a measure of social support. Contrary to previous evaluations of the MAF, data strongly suggest that the scale represents a unidimensional construct best represented by a single factor. Results indicate that the MAF is a useful measure of fatigue among pregnant and postpartum women.
