Emotional processing in anterior cingulate and medial prefrontal cortex

Negative emotional stimuli activate a broad network of brain regions, including the medial prefrontal (mPFC) and anterior cingulate (ACC) cortices. An early influential view dichotomized these regions into dorsal-caudal cognitive and ventral-rostral affective subdivisions. In this review, we examine a wealth of recent research on negative emotions in animals and humans, using the example of fear or anxiety, and conclude that, contrary to the traditional dichotomy, both subdivisions make key contributions to emotional processing. Specifically, dorsal-caudal regions of the ACC and mPFC are involved in appraisal and expression of negative emotion, whereas ventral-rostral portions of the ACC and mPFC have a regulatory role with respect to limbic regions involved in generating emotional responses. Moreover, this new framework is broadly consistent with emerging data on other negative and positive emotions.     

Sales manager cost control engagement: antecedents and performance implications

Many organizations face competing agendas by which they are expected to simultaneously grow sales output while controlling associated costs. At the interface of this organizational pressure and the sales force’s implementation of such initiatives is the sales manager. However, questions with significant implications remain regarding how a sales manager’s requisite engagement with cost control affects sales performance. To address this issue, the authors conceptualize and operationalize the notion of sales manager cost control engagement. Results from a survey of 178 business-to-business sales managers show the antecedent and consequence effects of sales manager cost control engagement. A variety of organizational factors are shown to effectively direct the sales manager’s attention to cost control, which in turn has a positive impact on cost-related sales performance. These findings add to an emergent body of research aimed at understanding key skills required of sales managers for driving sales performance as well as provide a novel perspective for sales managers to consider when balancing pressures between cost inputs and sales outputs. Several theoretical and managerial implications are offered, as are future research directions.     

Strategic regulation of grain size in memory reporting

To increase their report accuracy, rememberers may either withhold information that they feel unsure about or provide relatively coarse information that is unlikely to be wrong. In previous work (A. Koriat & M. Goldsmith, 1996c), the authors delineated the metacognitive monitoring and control processes underlying the decision to volunteer or withhold particular items of information (report option) and examined how these processes are used in the strategic regulation of memory accuracy. This article adapts that framework to address control over the grain size (precision-coarseness) of the information that people report. Results show that rememberers strategically regulate the grain of their answers to accommodate the competing goals of accuracy and informativeness. The metacognitive processes underlying this regulation are elucidated.     

Contextual Effects on the Gendered Division of Housework: A Cross-Country and Cross-Time Analysis

Individuals who espouse an egalitarian gender ideology as well as economically independent women benefit from a more egalitarian division of housework. Although these two individual-level characteristics affect the gender division of housework, each suggests a different mechanism; the former is anchored within an economic logic and the latter within a cultural one. Using data of 25 countries from the 2002 and 2012 “Family and Changing Gender Roles” modules of the International Social Survey Program, we examine whether a country’s mean gender ideology and women’s labor force participation (WLFP) rate have a distinct contextual effect beyond these individual-level effects. We predict that the division of housework between married or cohabitating partners will be more egalitarian in countries with higher WLFP rates and in countries with more egalitarian attitudes, even after controlling for the two variables at the individual level. Given the cross-country convergence in WLFP, but not in gender ideology, we expect the effect of WLFP to decline over time and the effect of gender ideology to remain salient. Indeed, our multi-level analysis indicates that the net effect of WLFP, which was evident in 2002, had disappeared by 2012. By contrast, the net contextual effect of gender ideology, which was not significant in 2002, had become an important determinant of housework division by 2012. We conclude that further changes will depend on a country’s prevalent gender ideology because the equalizing effect of WLFP on the division of housework may have reached its limit.

     

Visual Attention Patterns of Socially Anxious Individuals When Using Facebook: An Eye Tracking Study

Social networking sites (SNSs) are an increasingly used medium for social interactions. For socially anxious individuals, SNS-based communication is often preferred over traditional face-to-face socializing. Yet, research on SNSs usage and social anxiety is still less common, with extant studies being mostly correlational among healthy nonanxious participants. Conversely, here, we examined differences in actual gaze patterns to social and nonsocial stimuli between socially anxious and nonanxious individuals while using Facebook. Socially anxious and nonanxious student participants freely viewed a genuine Facebook profile page designed for the present study, for 3.5 minutes, containing 12 social and 12 nonsocial picture stimuli. Gaze patterns on social and nonsocial areas of interest (AOIs) were explored. Subjective uneasiness experienced when viewing the social pictures and state anxiety were also assessed. Finally, 2 weeks following the task, we evaluated participants’ willingness to participate in a follow-up (fictitious) study that required them to passively view their own Facebook profile, and then to actively use it. Results showed that compared with nonanxious participants, socially anxious participants demonstrated a viewing pattern less favoring social pictures, reflecting an attentional avoidance tendency. A significant inverse correlation between subjective uneasiness and percent of dwell time spent on the social AOI emerged. Socially anxious participants also reported higher levels of state anxiety, which was significantly positively correlated with uneasiness scores. Finally, socially anxious participants were also less willing to actively use their Facebook profile page. This study suggests that social anxious individuals are characterized by attentional and behavioral avoidance tendencies when using Facebook.     

Texture development during cross rolling of a dual-phase Fe–Cr–Ni alloy: experiments and simulations

Texture development during multi-step cross rolling of a dual-phase Fe–Cr–Ni alloy has been investigated. X-ray diffraction was used to investigate changes in crystallographic texture of both the constituent phases (austenite and ferrite) through changes in orientation distribution function. After deformation, rotated brass (rotated along φ₁, i.e. the sample normal direction ND), along with a weak cube texture was observed in austenite, while a strong rotated cube texture was obtained in ferrite. Texture was also simulated for various strains using a co-deformation model by self-consistent visco-plastic (VPSC) formulation. Simulations showed strong rotated brass texture in austenite and a strongly rotated cube, α-fibre (sample rolling direction RD //<1 1 0>) and γ-fibre (ND //<1 1 1>) in ferrite after highest strain (ε_t = 1.6). VPSC models could not effectively capture the change in crystallographic texture during cross rolling. In ferrite, simulations showed an overestimation of γ-fibre component and an underestimation of rotated cube component. Simulated texture of austenite, on the other hand, showed an overestimation of rotated brass with an absence of cube component. The results are rationalised based on the possible role of shear banding and activation of non-octahedral slip system during cross rolling, both of which are not incorporated in conventional VPSC models.     

Evaluating Triple P Online: A Digital Parent Training Program for Child Behavior Problems

Triple P Online (i.e., TPOL; www2.tripleponline.net) is an online self-help parent training program aimed at reducing child behavior problems through “positive parenting practices”—available at time of review for $79.95. TPOL is comprised of 8 video-based modules that also incorporate in-session activities and homework. Randomized control trials have shown that TPOL effectively reduces child behavior problems. The program’s main strengths include very high-quality content with an abundance of relevant and easily locatable resources, an easy-to-use interface, and a professional look and feel. The program’s main weakness lies in its lack of monitoring and adaptation to the user’s state (e.g., child’s and parent’s behaviors), and real-time reminders for desired actions. Altogether, TPOL is an extremely valuable and important resource for families seeking evidence-based treatment for child behavior problems.     

Taxometric and factor analytic models of anxiety sensitivity: integrating approaches to latent structural research

This study represents an effort to better understand the latent structure of anxiety sensitivity (AS), as indexed by the 16-item Anxiety Sensitivity Index (ASI; S. Reiss, R. A. Peterson, M. Gursky, & R. J. McNally, 1986), by using taxometric and factor-analytic approaches in an integrative manner. Taxometric analyses indicated that AS has a taxonic latent class structure (i.e., a dichotomous latent class structure) in a large sample of North American adults (N=2,515). As predicted, confirmatory factor analyses indicated that a multidimensional 3-factor model of AS provided a good fit for the AS complement class (normative or low-risk form) but not the AS taxon class (high-risk form). Exploratory factor analytic results suggested that the AS taxon may demonstrate a unique, unidimensional factor solution, though there are alternative indications that it may be characterized by a 2-factor solution. Findings suggest that the latent structural nature of AS can be conceptualized as a taxonic latent class structure composed of 2 types or forms of AS, each of these forms characterized by its own unique latent continuity and dimensional structure.     

Smoking motives in the prediction of affective vulnerability among young adult daily smokers

The primary aim of this study was to examine whether smoking to reduce negative affect was uniquely related to a range of affective vulnerability factors (e.g., anxiety sensitivity, anxious arousal, and negative affectivity) among daily smokers. Participants were 276 young adult daily smokers (124 females; M(age)=25.12, SD=10.37). Partially consistent with prediction, the motivation to smoke to reduce negative affect was significantly related to anxiety sensitivity and negative affectivity, but not anxious arousal; the observed significant effects were above and beyond other theoretically relevant factors (e.g., smoking rate, years smoked, age, gender). In contrast to prediction, habitual smoking motives demonstrated significant incremental associations with anxiety sensitivity and anxious arousal symptoms. These results suggest that there are important associations between certain smoking motives and negative affective states and that such relations are not attributable to other smoking factors (e.g., smoking rate).     

Sixteen-item Anxiety Sensitivity Index: confirmatory factor analytic evidence, internal consistency, and construct validity in a young adult sample from the Netherlands

The present investigation examined the factor structure, internal consistency, and construct validity of the 16-item Anxiety Sensitivity Index (ASI; Reiss Peterson, Gursky, & McNally 1986) in a young adult sample (n = 420) from the Netherlands. Confirmatory factor analysis was used to comparatively evaluate two-factor, three-factor, and four-factor models of the anxiety sensitivity construct. Support was found for a hierarchical structure of anxiety sensitivity, with one global higher-order factor and four lower-order factors. Internal consistency for the global and lower-order factors of the 16-item ASI was adequate. Convergent and discriminant associations between the 16-item ASI and general mood and panic-specific variables were consistent with anxiety sensitivity theory. In addition, incremental validity of the anxiety sensitivity construct was established, relative to negative affectivity, for unexpected panic attacks and agoraphobic avoidance.
