Group-directed criticism in Indonesia: Role of message source and audience

Research in individualist cultures has shown that group members are more likely to agree with criticisms of their group when the criticisms are made by another ingroup member as opposed to an outgroup member (the intergroup sensitivity effect). However, evaluations of ingroup critics are often harsher when they take their comments to an outgroup audience. In light of research on facework and tolerance for dissent, it seems important to test whether these effects are generalizable to a collectivist culture. Indonesian Muslims ( N  = 191) received a criticism of their religion stemming either from another Muslim or a Christian, and published in either a Muslim or a Christian newspaper. Participants agreed with the comments more when they were made by an ingroup as opposed to an outgroup member. Furthermore, consistent with previous research in Australia, the effects of audience on agreement were moderated by levels of group identification. Results are discussed in relation to theory about the functional role internal critics can play in group life.     

Maternal sensitivity moderates the impact of prenatal anxiety disorder on infant responses to the still-face procedure

Animal studies have demonstrated the interactive effects of prenatal stress exposure and postnatal rearing style on offspring capacity to manage stress. However, little is known about how parenting quality impacts the association between maternal prenatal anxiety and stress reactivity in human infants. This prospective study examined the impact of prenatal anxiety disorder and maternal caregiving sensitivity on infants’ responses to a standardised interactive stressor (still-face procedure). Eighty-four women completed a clinical interview during pregnancy to assess anxiety symptoms meeting DSM-IV diagnostic criteria. At infant age 7 months, maternal sensitivity to infant distress and infant negative affect were observed and coded during the still-face procedure. Maternal postnatal (concurrent) anxiety and depression were also assessed at this time. Results indicated a negative association between maternal sensitivity to infant distress and infant negative affect responses to the still-face procedure. An unexpected finding was a positive association between parity and infant reactivity. The main effect for sensitivity was qualified by a significant interaction, p < .05, suggesting that the impact of sensitivity was particularly marked among infants of women who experienced an anxiety disorder during pregnancy. This finding is consistent with a cumulative risk model suggesting that maternal prenatal anxiety and quality of maternal care act in concert to shape infant outcomes.     

Empathy constrained: Prejudice predicts reduced mental simulation of actions during observation of outgroups

Perception-action-coupling refers to the vicarious activation of the neural system for action during perception of action, and is considered important for forms of interpersonal sensitivity, including empathy. We hypothesize that perception-action-coupling is limited to the ingroup: neural motor networks will fire upon the perception of action, but only when the object-person belongs to the ingroup; if the object-person belongs to an outgroup these motor neurons will not fire. Using electroencephalographic oscillations as an index of perception-action-coupling, we found exactly this: participants displayed activity over motor cortex when acting and when observing ingroups act, but not when observing outgroups - an effect magnified by prejudice and for disliked groups (South-Asians, then Blacks, followed by East Asians). These findings provide evidence from brain activity for yet another detrimental aspect of prejudice: a spontaneous and implicit simulation of others’ action states may be limited to close others and, without active effort, may not be available for outgroups.

敏感性是心理负荷测量技术可靠性的基本要求。该研究利用主任务绩效、次任务绩效、主观“加权负荷”评定和心率变异变化率四项指标,在计算机模拟情境下对视觉追踪作业心理负荷进行多变量评估实验。结果发现,以上述四项指标为基础建立的“综合加权评估指数”是一项较有效的评估指标,其敏感性远高于任何单独的评定。     

Delayed matching-to-sample performance: Effects of relative reinforcer frequency and of signaled versus unsignaled reinforcer magnitudes

Six pigeons were trained on a delayed red-green matching-to-sample task that arranged four delays within sessions. Matching responses intermittently produced either 1.5-s access to food or 4.5-s access to food, and nonmatching responses produced either 1.5-s or 4.5-s blackout. Two phases were conducted: a signaled phase in which the reinforcer magnitudes (small and large) were signaled by houselights (positioned either on the left or right of the chamber), and an unsignaled phase in which there was no correlation between reinforcer magnitude and houselight position. In both phases, the relative frequency with which red and green matching responses produced food was varied across five values. Both matching accuracy and the sensitivity of performance to the distribution of reinforcers for matching responses decreased with increasing delays in both phases. In addition, accuracy and reinforcer sensitivity were significantly lower on signaled small-reinforcer trials compared with accuracy and sensitivity values on signaled large-reinforcer trials and on both types of unsignaled trials. These results are discussed in the context of research on both nonhuman animal and human memory.     

Sensitivity analysis in factor analysis: Difference between using covariance and correlation matrices

Influence curves of some parameters under various methods of factor analysis have been given in the literature. These influence curves depend on the influence curves for either the covariance or the correlation matrix used in the analysis. The differences between the influence curves based on the covariance and the correlation matrices are derived in this paper. Simple formulas for the differences of the influence curves, based on the two matrices, for the unique variance matrix, factor loadings and some other parameter are obtained under scale-invariant estimation methods, though the influence curves themselves are in complex forms.The authors are most grateful to the referees, the Associate Editor, the Editor and Raymond Lam for helpful suggestions for improving the clarity of the paper.     

Free to be me: The relationship between the true self,rejection sensitivity,and use of online dating sites

Prior research (Blackhart et al., 2014) found that rejection-sensitive individuals are more likely to use online dating sites. The purpose of the current research was to explain the relationship between rejection sensitivity and online dating site usage. Study 1 examined whether true self mediated the relation between rejection sensitivity and online dating. Study 2 sought to replicate the findings of Study 1 and to examine whether self-disclosure moderated the relationship between true self and online dating in the mediation model. Results replicated those found by Blackhart et al. and also found that true self mediated the relationship between rejection sensitivity and online dating site usage. These findings suggest that rejection-sensitive individuals feel they can more easily represent their “true” selves in online environments, such as online dating sites, which partially explains why they are more likely to engage in online dating.     

Anxiety sensitivity as a predictor of panic disorder symptoms: a prospective 3-year study

Background and Objectives: Anxiety sensitivity (AS) is the fear of anxiety symptoms, a feature proven to be an important vulnerability factor for anxiety pathogenesis. The aim of this study was to examine whether AS (as well as its factors) predicts the onset of panic disorder symptoms when controlling for the contribution of trait anxiety.

Design: We conducted a prospective 3 year follow up study.

Methods: The participants, students at the Humanities and Social Sciences in Zagreb (N?=?1087), completed an Anxiety Sensitivity Index and State-Trait Anxiety Inventory (Trait form) and, after a period of three years, were asked to self-assess criteria for panic disorder (according to the DSM-5).

Results: The predictive validity of AS for the onset of panic disorder symptoms, regardless of trait anxiety, was confirmed. Furthermore, the physical concerns dimension of AS was the only significant predictor of panic disorder symptoms. The optimal cutoff score of 25 on the ASI provides poor to moderate accuracy indices in detecting participants who will manifest panic disorder symptoms in the next three years.

Conclusion: This study contributes to our current understanding of AS as a prospective risk factor for panic disorder symptoms.     

Anxiety sensitivity cognitive concerns drive the relation between anxiety sensitivity and symptoms of depression

Depression is typically treated as a homogeneous construct despite evidence for distinct cognitive, affective, and somatic symptom dimensions. Anxiety sensitivity (AS; the fear of consequences of anxiety symptoms) is a cognitive risk factor implicated in the development of depressive symptoms. However, it is unclear how lower order AS dimensions (i.e. physical, cognitive, and social concerns) relate to depressive symptom factors. Confirmatory factor analysis, followed by structural equation modeling, were conducted to examine the factor structure of depression and to then examine the relations between these factors and the lower order factors of AS. This study was conducted in a sample of 374 adults (M age = 35.5, 54.3% female) with elevated levels of psychopathology (89.2% meeting criteria for at least one DSM-5 diagnosis, 25.6% primary depressive disorder). In this study a two-factor model of depression, composed of Cognitive and Affective/Somatic factors, was superior to one- and three-factor solutions. AS cognitive concerns were related to both cognitive and affective/somatic symptoms of depression. Neither of the other AS dimensions was related to depression symptom dimensions. These findings provide a better understanding of the relations between AS and depression symptoms.
