Bottom-Up and Top-Down Processes in Emotion Generation: Common and Distinct Neural Mechanisms

ABSTRACT— Emotions are generally thought to arise through the interaction of bottom-up and top-down processes. However, prior work has not delineated their relative contributions. In a sample of 20 females, we used functional magnetic resonance imaging to compare the neural correlates of negative emotions generated by the bottom-up perception of aversive images and by the top-down interpretation of neutral images as aversive. We found that (a) both types of responses activated the amygdala, although bottom-up responses did so more strongly; (b) bottom-up responses activated systems for attending to and encoding perceptual and affective stimulus properties, whereas top-down responses activated prefrontal regions that represent high-level cognitive interpretations; and (c) self-reported affect correlated with activity in the amygdala during bottom-up responding and with activity in the medial prefrontal cortex during top-down responding. These findings provide a neural foundation for emotion theories that posit multiple kinds of appraisal processes and help to clarify mechanisms underlying clinically relevant forms of emotion dysregulation.     

Signaling threat: how situational cues affect women in math, science, and engineering settings

This study examined the cues hypothesis, which holds that situational cues, such as a setting's features and organization, can make potential targets vulnerable to social identity threat. Objective and subjective measures of identity threat were collected from male and female math, science, and engineering (MSE) majors who watched an MSE conference video depicting either an unbalanced ratio of men to women or a balanced ratio. Women who viewed the unbalanced video exhibited more cognitive and physiological vigilance, and reported a lower sense of belonging and less desire to participate in the conference, than did women who viewed the gender-balanced video. Men were unaffected by this situational cue. The implications for understanding vulnerability to social identity threat, particularly among women in MSE settings, are discussed.     

A note on the sociological eye and the discovery of a new Durkheim text

The text consisting of recently discovered student notes taken during Émile Durkheim's 1883–1884 lycée lectures on philosophy bears few signs of the social realist perspective with which Durkheim's later work has been identified. Though some scholars have argued that Durkheim's thought was sociological almost from the start, the lectures suggest that Durkheim's sociological eye did not develop until well after the completion of his schooling at the École Normale Supérieure in 1882. This finding is consistent with accounts of Durkheim's intellectual development that stress the importance of his exposure to German scholarship, as well as his consideration of the work of Comte and Rousseau, in the years following 1885. However, these accounts have generally failed to distinguish between the development of Durkheim's philosophy of social realism and the unfolding of the practical worldview that constituted his sociological perspective. This failure is not unique to Durkheimian scholarship, as there exists no general theory of the sociological eye on which historians of ideas can draw. This short essay makes the case that Durkheim's lycée lectures should be used to help develop such a theory. © 1996 John Wiley & Sons, Inc.     

How some dyads “fail”: A qualitative analysis with implications for nursing practice

Videotapes of 20 mentally ill and 20 matched well mothers with their three month through 36-month-old-children were analyzed in a two-part study. Part I tested the usefulness of the Maternal Sensitivity Scale and the Maternal Effectiveness Scale in discriminating mentally ill and well mother-child dyads. Part II analyzed the interactions of those dyads that were rated low on the scales in Part I (n = 13) to explore maladaptive patterns of behavior which may explain how the insensitivity and ineffectiveness unfolded. Seven characteristics that were observed to contribute to the interactive disorganization in these 13 dyads are described and discussed.     

TRACKING THE GENDER PAY GAP: A CASE STUDY

This article provides a short introduction to standard considerations in the formal study of wages and illustrates the use of multiple regression and resampling simulation approaches in a case study of faculty salaries at one university. Multiple regression is especially beneficial where it provides information on strength of association, specific dollar estimates, and the option to identify outliers by gender. Resampling simulation allows for analysis at the department level and is beneficial where distributions depart substantially from normal, particularly where there are unequal error variances. Results indicate that both regression and simulation methods provided evidence of a sizable pay gap associated with gender, even after controlling for rank, academic field, and years of service. The gap occurs in fields traditionally viewed as female as well as science fields with typically lower female representation. Finally, we discuss implications for remediation based on these models.     

Maternal confidence,knowledge, and quality of mother-toddler interactions: A preliminary study

The purpose of this study was to examine the relationships among maternal confidence, knowledge of child development, and quality of mother-toddler interactions using self-efficacy (Bandura, 1977, 1989) as the theoretical framework. Using the Toddler Care Questionnaire, 50 mothers of toddlers were asked to estimate their confidence in their ability to parent their toddlers. Mothers also completed the Knowledge of Infant Development Questionnaire and were videotaped in their homes during a structured interaction with their toddlers. Maternal confidence was positively correlated with maternal knowledge of child development and parenting. The relationships among mother's knowledge of child development, maternal confidence, and quality of mother-toddler interactions were examined by a 2 × 3 analysis of variance with quality of interactions as the dependent variable. There were no significant main effects for maternal knowledge or confidence on quality of mother-toddler interactions, but there was a significant interaction effect. That is, the combined effects of maternal knowledge and confidence were related to quality of mother-toddler interactions. These results may explain previous inconsistencies in the literature regarding the significance of maternal confidence for mother-child interactions and are congruent with self-efficacy theory. Implications for interventions are discussed.     

Long-term consequences of childhood physical and psychological maltreatment

This study assessed whether some of the correlates of learned helplessness—depression, low self-esteem, and a maladaptive attributional style—are long-term consequences of child abused. In this study, 260 subjects were identified as physically abused, psychologically abused, both physically and psychologically abused, or nonabused, based on responses to the Child Abuse Questionnaire (CAQ). Subjects were tested for levels of nonclinical depression via the Beck Depression Inventory (BDI), for levels of self-esteem via the Rosenberg Self-Esteem Scale (RSE), and for the adaptiveness of attributional style via the Attributional Style Questionnaire (ASQ). It was hypothesized that each of the three abuse groups would differ from the control group on the three dependent measures; differences among the three abuse groups were also explored. Three one-way analyses of variance indicated that (1) BDI scores reflected a greater tendency toward depression in subjects reporting both types of abuse than in nonabused subjects or in subjects reporting either psychological or physical abuse, (2) subjects reporting psychological abuse only or both psychological and physical abuse showed lower self-esteem than did nonabused subjects, and (3) abused subjects did not seem to exhibit a more maladaptive attributional style than that of nonabused subjects. In addition, multiple linear regression analyses pointed to psychological abuse as a critical variable in predicting levels of depression, self-esteem, and attributional style, when physical abuse effects were controlled. Controlling for the effects of psychological abuse, however, indicated that physical abuse did not significantly contribute to the variance in these variables. Implications for the learned helplessness model and for future research are discussed. © 1992 Wiley-Liss, Inc.
