Maternal self-regulation,relationship adjustment,and home chaos: Contributions to infant negative emotionality

There has been increasing interest in the direct and indirect effects of parental self-regulation on children's outcomes. In the present investigation, the effects of maternal self-regulation, home chaos, and inter-parental relationship adjustment on broad and specific indicators of infant negative emotionality (NE) were examined. A sample of maternal caregivers and their 4-month-old infants (N = 85) from a rural community participated. Results demonstrated that better maternal self-regulation was associated with lower infant NE broadly, as well as with lower infant sadness and distress to limitations/frustration and better falling reactivity (i.e., emotion regulation), specifically. Maternal self-regulation also predicted less chaotic home environments and better maternal inter-parental relationship adjustment. Findings also supported the indirect effects of maternal self-regulation on broad and specific indicators of infant NE through home chaos and maternal relationship adjustment. Some differential effects were also identified. Elevated home chaos appeared to specifically affect infant frustration/distress to limitations whereas maternal relationship adjustment affected broad infant NE, as well as several specific indicators of infant NE: frustration/distress to limitations, sadness, and falling reactivity. In conjunction with other recent investigations that have reported the effects of maternal self-regulation on parenting, the findings in the present investigation suggest that parental self-regulation may influence children's outcomes through several proximal environmental pathways.     

Sex differences in domain-specific depressogenic cognitive responses to negative and positive life events

Maladaptive cognitive responses to stressful life events represent well-replicated risk factors for depression. Research indicates that stressful life events that are dependent on the individual to occur or are interpersonal may generate more maladaptive cognitive responses than those that are independent and/or non-interpersonal. The current study examined the roles of sex and life event domains in eliciting depressogenic cognitive responses. Participants were 212 (71% female) undergraduate students who completed seven weekly questionnaires on participant-identified most negative and most positive life events over the previous 7 days. Additionally, participants reported levels of brooding and cognitive style in response to the most negative event and levels of positive rumination and dampening in response to the most positive event. Data were analyzed using mixed ANOVAs. Results indicated that females engaged in greater brooding regardless of event dependency. In addition, dependent and interpersonal life events generated greater brooding while dependent and non-interpersonal negative events generated greater negative cognitive style. An interaction between sex and domain was observed for dampening positive life events, such that males did not differ between interpersonal and non-interpersonal life events while females were more likely to dampen following interpersonal life events than non-interpersonal events.     

Comparing positive and negative patterning in human learning

In human causal learning, positive patterning (PP) and negative patterning (NP) discriminations are often acquired at roughly the same rate, whereas PP is learned faster than NP in most experiments with nonhuman animals. One likely reason for this discrepancy is that most causal learning scenarios encourage participants to treat the presentation and omission of the relevant outcome as two events of comparable significance and likelihood. To investigate this, the current experiments compared PP and NP using a predictive learning paradigm based on a mock gambling task. In Experiment 1, one outcome (winning) was made more salient by being less frequent than the alternative outcome (losing). Under these circumstances, PP was learned faster than NP. In Experiment 2, subjects learned two PP and two NP discriminations, one involved win versus no change outcomes, the other involved lose versus no change outcomes. The subjects learned PP faster than NP, but only when discriminating win from no change. We argue that a difference in difficulty between PP and NP relies on a difference in the salience of the outcomes, consistent with the predictions of a relatively simple model of associative learning.     

Normative and idiosyncratic measures of positive and negative affect in sport

Objectives: The purposes of the study were to: (a) ascertain the degree of similarity amongst normative and idiosyncratic measures of affect; (b) test the notion of reversal effects on the functional impact and the hedonic tone of emotions; (c) analyse the differences on the intensity of facilitating-positive, facilitating-negative, inhibiting-positive, and inhibiting-negative performance emotion content categories, and (d) test whether competitive trait anxiety intensity could predict pre-performance normative or idiosyncratic negative affect intensity.Design: A cross-sectional study design was employed using normative and idiosyncratic measures of affect.Methods: Experienced male soccer and volleyball players (N =124) were individually assessed. Normative scales were the Positive and Negative Affect Schedule (PANAS) used as a sport-specific trait measure of competitive affect, and the Sport Anxiety Scale (SAS) administered for the assessment of competitive trait anxiety. Idiosyncratic affect occurring prior to or during optimal and poor competitions was identified in the conceptual framework of the Hanin's Individual Zones of Optimal Functioning (IZOF) model (Hanin, Y.L. (1997). Emotions and athletic performance: Individual zones of optimal functioning model. European Yearbook of Sport Psychology, 1, 29–72).Results: Findings revealed low overlap amongst the PANAS items and the idiosyncratic items, reversal effects on the functional impact and the hedonic tone of emotions, higher level of positive affect associated with optimal performance when compared with all other affect categories, and lower levels of facilitating-negative category when compared with the facilitating-positive. Moreover, sport trait anxiety intensity was found to predict negative affect intensity as assessed by the PANAS normative scales and by the idiosyncratic items. For idiosyncratic affect, however, significant differences emerged only when comparing individuals with very high or very low anxiety symptoms.Conclusions: Idiosyncratic affect scales together with normative scales are recommended for research and applied purposes. The functional impact as well as the hedonic tone of emotion items need to be examined according to individual perception.     

Physical health, positive and negative affect, and personality: A longitudinal analysis

This study used structural equation modeling to examine longitudinal relations among physical health, personality and mood in a sample of 360 college students. Research focused on the longitudinal associations among physical health and mood and their systematic relations with the Big Five personality dimensions of Extraversion and Neuroticism. Longitudinal analyses over successive 1-month intervals revealed lagged reciprocal effects between physical health and negative affect. After controlling for the effect of negative affect, physical health influenced subsequent positive affect, but positive affect did not influence subsequent physical health. Implications of these findings for subsequent research on health, personality, and emotions are discussed.     

Dimensions of temperament and depressive symptoms: Replicating a three-way interaction

High negative emotionality (NE), low positive emotionality (PE), and low self-regulatory capacity (i.e., effortful control or EC) are related to depressive symptoms and furthermore, may moderate one another’s relations to such symptoms. Indeed, preliminary evidence suggests they may operate in a three-way interaction (Dinovo & Vasey, 2011), but the replicability of that finding remains unknown. Therefore, we tested this NE × PE × EC interaction in association with depressive symptoms in 5 independent samples. This interaction was significant in 4 of the 5 samples and a combined sample and approached significance in the fifth sample. In contrast, the NE × PE × EC interaction was unrelated to general anxious symptoms and thus may be specific to symptoms of depression. Implications, directions for future research, and limitations are discussed.     

Vulnerability associations and symptoms of post-traumatic stress disorder in soldiers deployed to Iraq

The purpose of this prospective study was to examine whether explicit and implicit vulnerability associations before and after trauma exposure predict the onset and persistence of post-traumatic stress disorder (PTSD) symptoms. The implicit association test (IAT) was modified to assess associations of self with vulnerability related cues. Dutch soldiers completed the IAT 6 weeks before being deployed to Iraq, and again 5 months upon return home. They also rated an explicit vulnerability scale. PTSD symptoms were assessed 5 and 15 months after deployment with a clinical interview and questionnaire. The results showed that (1) the pre-deployment vulnerability measures did not predict PTSD symptoms at 5 months, (2) both explicit and implicit post-deployment vulnerability measures explained unique variance in concurrent PTSD symptoms, over and above pre-existing neuroticism, and (3) only the explicit post-deployment vulnerability measure predicted unique variance in later PTSD symptoms (at 15 months), after controlling for earlier symptoms. This was no longer the case after controlling for neuroticism. The results suggest that strong implicit associations between the self and vulnerability are a consequence rather than a cause of PTSD symptoms.     

Perfectionistic strivings and perfectionistic concerns interact to predict negative emotionality: Support for the tripartite model of perfectionism in Canadian and Chinese university students

For most individuals, perfectionistic strivings and perfectionistic concerns coexist to varying degrees. While there is agreement that within-person combinations of perfectionistic strivings and perfectionistic concerns produce meaningful “subtypes”, the number and characterization of these within-person combinations is still debated. The two most prominent person-centered perfectionism models (the tripartite model and the 2 × 2 model) offer differing characterizations of how perfectionistic strivings effects perfectionistic concerns’ relationship with psychological outcomes. According to the 2 × 2 model, perfectionistic strivings buffers against the negative effects of perfectionistic concerns. The 2 × 2 model thus claims the most deleterious within-person combination of perfectionistic strivings and perfectionistic concerns is low strivings and high concerns. In contrast, according to the tripartite model, perfectionistic strivings exacerbates the maladaptive effects of perfectionistic concerns. The tripartite model thus claims the most maladaptive within-person combination of perfectionistic strivings and perfectionistic concerns is high strivings and high concerns. The present study tested these competing claims in a group of English speaking Canadians and a group of Mandarin speaking Chinese. Results support the tripartite model of perfectionism.     

Positive affectivity and attentional control moderate the link between negative affectivity and depressed mood

Research and theory suggest that deficits in trait positive affectivity (PA) and in capacity for executive control of attention (i.e., attentional control or AC) may each intensify risk for depressive symptoms associated with high trait negative affectivity (NA). In contrast, high levels of PA and AC should protect against that risk. However, prospective tests of such predictions are rare. Furthermore, if PA and AC both modulate NA-related risk, it remains to be seen if those effects are independent and complementary or if they operate in an overlapping manner. This study assessed baseline temperament and change in depressed mood across one month in a sample of 125 adolescents. Results supported both PA and AC as modulators of NA’s association with changes in depressed mood. Furthermore, results suggested that these modulating effects are largely non-overlapping and complementary, such that when both PA and AC are low, high NA predicts increases in depressed mood. In contrast, high NA predicts decreases in depressed mood when both PA and AC are high. Limitations of these findings, directions for future research, and implications for prevention are discussed.     

Intensity of positive and negative emotions: Explaining the association between personality and depressive symptoms

The aim was to examine to what extent emotional intensity accounted for associations between the Big Five personality dimensions and depressive symptoms. Study 1 tested the model cross-sectionally, using survey data of 266 Dutch social science students. Study 2 experimentally examined how personality dimensions were related to emotional reactivity after exposure to various emotional stimuli. Dutch psychology students (N = 130) reported on their personality and viewed an amusing or sad film clip, after which the change in intensity of experienced positive and negative emotions was assessed. Individuals scoring higher on neuroticism generally experienced more intense negative emotions, through which they experienced a higher level of depressive symptoms. Individuals who were more agreeable experienced a lower level of depressive symptoms indirectly through higher general intensity of positive emotions. More agreeable individuals showed stronger increase in negative emotions and stronger decrease in positive emotions, though after exposure to the sad stimulus only. Although replication is needed, our results offer empirical support for a more taylor-made approach in decreasing nonclinical depressive symptoms taking into account both personality characteristics and emotion regulation.     

The mediating role of positive relations with others in associations between depressive symptoms, social skills, and perceived stress

This study was designed to examine the role of positive relations with others as a mediator of the association between poor social skills and depression and between depression and increased perceptions of stress. To test these two models, data were collected from 179 young adults assessed three times over the course of 4 months. Sobel’s product of coefficients test and lower-level mediation modeling were used to evaluate these predictions. The results showed that positive relations with others completely mediated the negative association between social skills and depression. Social skills also moderated the positive association between depression and perceptions of stress. These findings illustrate how positive relations with others function to promote psychological well-being.     

Septal damage in infant and adult rats: Effects on activity,emotionality, and muricide

Septal lesions produced signs of increased emotionality in the adult rat, the septal syndrome (hyperresponsiveness to handling; in the open field: decreased rearing and ambulation activity, increased defecation, deficient habituation) being more or less complete and more or less marked depending on the age at which the lesion was performed (7 days or 3 months), the extent of the lesion (restricted to the septum or extending to more ventrally located structures) and the environmental conditions in which the animals were reared (in groups or in isolation). All septal lesions provoked a similar and significant increase in the probability of occurrence of mouse-killing behavior, irrespective of age of operation, extent of lesion and kind of rearing environment. In a 24-hour actography starting at 11:30 a.m., the rats septalectomized at adult age were less active than controls during the initial period, while all septals were markedly more active than controls during the night period. Early septal lesions only transiently disrupted weight gain. The results obtained point to complex interactions between the effects of early brain damage and environmental conditions.     

The Minnesota Multiphasic Personality Inventory-2 Restructured Form in National Guard soldiers screening positive for posttraumatic stress disorder and mild traumatic brain injury

The Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2 RF) was administered to 251 National Guard soldiers who had recently returned from deployment to Iraq. Soldiers were also administered questionnaires to identify posttraumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI). On the basis of responses to the screening instruments, the National Guard soldiers who produced a valid MMPI-2 RF were classified into four groups: 21 soldiers who screened positive for PTSD only, 33 soldiers who screened positive for mTBI only, 9 soldiers who screened positive for both conditions, and 166 soldiers who did not screen positive for either condition. Results showed that the MMPI-2 RF was able to differentiate across the groups with the MMPI-2 RF specific problem scale Anxiety adding incrementally to MMPI-2 Restructured Clinical scales in predicting PTSD. Both MMPI-2 RC1 (Somatic Complaints) and MMPI-2 RF head pain complaints predicted mTBI screen but did not add incrementally to each other. Of note, all of the MMPI-2 RF validity scales associated with overreporting, including Symptom Validity-Revised (FBS-r), were not significantly elevated in the mTBI group. These findings support the use of the MMPI-2 RF in assessing PTSD in non-treatment-seeking veterans. This further suggests that a positive screen for mTBI alone is not associated with significant emotional disturbance.     

The effects of rumination and negative cognitive styles on depression: a mediation analysis

Research on cognitive models of depression has identified negative cognitive styles and rumination as risk factors for depression. The present study examined the hypothesis that rumination mediates the effect of negative cognitive styles on depression. Specifically, we evaluated the differential effects of two aspects of rumination, characterized by brooding and reflection, on the relationship between negative cognitive styles and level of depressive symptoms. A total of 115 college students and 38 patients suffering from depressive disorders completed a battery of questionnaires measuring levels of depressive symptoms, brooding, reflection, and negative cognitive styles. The results support the notion that there exist two distinct dimensions of rumination and that, of the two, it is brooding and not reflection that mediates the relationship between negative cognitive styles and depression and contributes to its negative outcomes.     

Sex differences in maternal behaviors of immature rats: The role of emotionality

Immature rats are able to give maternal care to pups and may increase their inclusive fitness by helping newborn siblings. Immature males are generally reported to be more maternal than females. In this research we studied sex differences and the extent to which they may be due to a different emotional response to novelty. We studied maternal response in two groups of immature rats of both sexes: in the naive group, juveniles aged from 18 to 30 days were given one test and showed clear-cut sex differences. The experience group was submitted to repeated tests from 18 to 30 days of age, thus eliminating the effects of novelty: as a result, all differences between sexes disappeared. A second experiment was designed in 24-day-old females to differentiate the effects of repeated handling and exposure to the test situation from that of repeated exposure to pups; moreover, the effects of an anxiety-reducing drug (diazepam) were studied. Exposure to pups is particularly efficient in facilitating maternal response. Diazepam injection was also effective, but its control showed that the injection per se was responsible for the effect. In conclusion, our results stress the importance of response to novelty and suggest that sex differences in maternal behavior of immature rats may be modulated by different emotional responses by males and females. In fact, emotionality competes with, and may exert an inhibitory effect on, the expression of a vast array of behaviors. © 1994 Wiley-Liss, Inc.     

The relationship of positive and negative expressiveness to the processing of emotion information

The tendency to express emotions non-verbally is positively related to perception of emotions in oneself. This study examined its relationship to perception of emotions in others. In 40 healthy adults, EEG theta synchronization was used to indicate emotion processing following presentation of happy, angry, and neutral faces. Both positive and negative expressiveness were associated with higher emotional sensitivity, as shown by cortical responses to facial expressions during the early, unconscious processing stage. At the late, conscious processing stage, positive expressiveness was associated with higher sensitivity to happy faces but lower sensitivity to angry faces. Thus, positive expressiveness predisposes people to allocate fewer attentional resources for conscious perception of angry faces. In contrast, negative expressiveness was consistently associated with higher sensitivity. The effects of positive expressiveness occurred in cortical areas that deal with emotions, but the effects of negative expressiveness occurred in areas engaged in self-referential processes in the context of social relationships.     

A reduction in positive self-judgment bias is uniquely related to the anhedonic symptoms of depression

Identifying patterns of biased cognitive processing specific to depression has proved difficult. The tripartite model of mood disorders [Clark, L. A., & Watson, D. (1991). Tripartite model of anxiety and depression: psychometric evidence and taxonomic implications. Journal of Abnormal Psychology, 100, 316-336] suggests that a clearer processing ‘blueprint’ may emerge if depression is viewed dimensionally rather than categorically and by focusing on variations in the degree of positive, rather than negative, processing bias. To investigate this possibility, the present study examined the extent to which a reduced positive self-judgment bias previously found in depressed individuals relates to depression-specific anhedonic symptoms. Sixty participants with varying levels of anxiety and depression symptoms evaluated their own performance on a working memory task in the absence of external feedback. Overall, participants showed a positive self-judgment bias, overestimating the number of trials they had performed correctly relative to objective criteria. Consistent with the tripartite framework, the extent of this positive self-judgment bias was significantly and uniquely related to depression-specific symptoms, with the positive bias reducing as anhedonia severity increased across three different symptom measures.     

Emotional Constriction and Risk for Posttraumatic Stress: The Roles of Trauma History and Gender

Research suggests there are qualitative differences in emotionality across gender, with men being more emotionally constrictive than women. Constrictive emotionality has consistently been linked to posttraumatic stress disorder (PTSD) and because men are generally more emotionally constrictive, one could infer they are at increased risk for PTSD. However, research demonstrates that twice as many women are diagnosed with PTSD than men. In an undergraduate sample, men reported significantly greater emotional constriction, but significantly less posttraumatic stress severity in comparison to women. The gender differences in emotional constriction disappeared in a subsample of students who endorsed experiencing an upsetting event. Emotional constriction mediated the relationship between trauma and posttraumatic stress severity, although it was a stronger mediator for women than men.     

Combat exposure, psychological symptoms, and marital satisfaction in National Guard soldiers who served in Operation Iraqi Freedom from 2005 to 2006

In current military operations in Iraq and Afghanistan, US National Guard (NG) troops are serving longer deployments than ever before. Little is known, however, about how such deployments affect this population of individuals, relative to active component (AC) troops. This study investigated the extent of combat exposure, severity of post-deployment psychological symptoms, and general interpersonal functioning, as well as the interrelationships of these variables, in 50 NG soldiers who served a 12-month deployment in Iraq from 2005 to 2006. The results indicate that combat exposure and post-deployment post-traumatic stress symptoms in this sample are greater than those in NG veterans of past military operations, and similar to those of full-time soldiers in current operations. Furthermore, the patterns of interrelationships between combat exposure, psychological symptoms, and interpersonal variables were similar to those detected in prior research on AC troops. These results suggest that NG veterans of current military operations may require similar services as active duty veterans. Given that NG troops are less integrated into the military structure, specific outreach efforts may be needed to help NG veterans to receive such services.
