People differ in the extent to which they emphasize feelings of activation or deactivation in their verbal reports of experienced emotion, termed arousal focus (AF). Two multimethod studies indicate that AF is linked to heightened interoceptive sensitivity (as measured by performance on a heartbeat detection task). People who were more sensitive to their heartbeats emphasized feelings of activation and deactivation when reporting their experiences of emotion over time more than did those who were less sensitive. This relationship was not accounted for by several other variables, including simple language effects. Implications for the role of interoception in experienced emotion and the validity of self-reported emotion are discussed.  相似文献

The notion that visual attention can operate over visual objects in addition to spatial locations has recently received much empirical support, but there has been relatively little empirical consideration of what can count as an 'object' in the first place. We have investigated this question in the context of the multiple object tracking paradigm, in which subjects must track a number of independently and unpredictably moving identical items in a field of identical distractors. What types of feature clusters can be tracked in this manner? In other words, what counts as an 'object' in this task? We investigated this question with a technique we call target merging: we alter tracking displays so that distinct target and distractor locations appear perceptually to be parts of the same object by merging pairs of items (one target with one distractor) in various ways - for example, by connecting item locations with a simple line segment, by drawing the convex hull of the two items, and so forth. The data show that target merging makes the tracking task far more difficult to varying degrees depending on exactly how the items are merged. The effect is perceptually salient, involving in some conditions a total destruction of subjects' capacity to track multiple items. These studies provide strong evidence for the object-based nature of tracking, confirming that in some contexts attention must be allocated to objects rather than arbitrary collections of features. In addition, the results begin to reveal the types of spatially organized scene components that can be independently attended as a function of properties such as connectedness, part structure, and other types of perceptual grouping.  相似文献

Patterns of facilitation in three lexical decision studies reveal several properties of morphologically complex words that influence processing. In one study, effects of morphological (VOWED-VOW) similarity are contrasted with effects of either semantic (PLEDGE-VOW) or orthographic (VOWEL-VOW) similarity at two prime durations to show the distinctiveness of morphological processing. In a second study, we compare morphologically complex forms that are semantically transparent (CASUALLY-CASUALNESS) with opaque forms (CASUALTY-CASUALNESS) and show that opaque relatives are more similar to VOWEL-VOW type pairs than to transparent relatives. In the third study, we examine facilitation for complex targets (CALCULATION) preceded by prefixed (MISCALCULATE) and suffixed (CALCULATOR) relatives and show that the position of the base morpheme influences processing under cross-modal but not under purely visual presentation conditions. Taken collectively, under comparable presentation conditions, semantic transparency but not base morpheme position constrains morphological processing.  相似文献

Data from two multi-ethnic prospective studies of African American, Latina, and non-Hispanic White pregnant women were used to examine the influence of contextual factors on social support processes during pregnancy. Multiple types of support (perceived support, received support, support satisfaction, network support) and sources of support (baby's father, family, friends) were assessed. The role of ethnicity in social support was examined after controlling for the contribution of related contextual factors (SES, marital status, age, parity, employment) to these processes. The impact of ethnicity and related contextual factors differed across sources of social support. Ethnic differences in support from family and friends, but not from the baby's father, emerged. However, marital status was a consistent predictor of support from the baby's father, and SES was a consistent predictor of support from friends. Overall, the findings of two studies suggest that although ethnicity is associated with support from friends and family, other contextual factors, such as marital status and SES, influence support processes during pregnancy.  相似文献

Congenital adrenal hyperplasia (CAH) due to steroid 21-hydroxylase deficiency is a common autosomal recessive disorder due to mutations in the CYP21A2 gene. Since genetic counselors play a crucial role in educating families about inherited disorders, they need to have thorough knowledge regarding the pathophysiology of CAH especially the effects on the fetus, the complex genetics of this disorder, and the controversies surrounding experimental prenatal dexamethasone treatment. Affected female fetuses may have varying degree of virilization of the external genitalia. Starting in the 1980's, supraphysiologic glucocorticoid treatment was used to decrease the virilization of the external genitalia of affected female fetuses. However, recent clinical observations, animal studies and greater awareness of the details of human fetal adrenal physiology raise concerns regarding the safety of this prenatal treatment. We review the pathophysiology of CAH, the safety and ethical considerations of prenatal dexamethasone treatment and the views of multiple medical societies that conclude that this experimental therapy should only be done in prospective trials approved by ethical review boards.  相似文献

There are twice as many suicides as homicides in the United States, and the suicide rate is rising. Suicides increased 12% between 1999 and 2009. Mental health professionals often treat suicidal patients, and suicide occurs even among patients who are seeking treatment or are currently in treatment. Despite these facts, training of most mental health professionals in the assessment and management of suicidal patients is surprisingly limited. The extant literature regarding the frequency with which mental health professionals encounter suicidal patients is reviewed, as is the prevalence of training in suicide risk assessment and management. Most importantly, six recommendations are made to address the longstanding insufficient training within the mental health professions regarding the assessment and management of suicidal patients.  相似文献

It seems obvious that what you see influences what you feel, but what if the opposite were also true? What if how you feel can shape your visual experience? In this experiment, we demonstrate that the affective state of a perceiver influences the contents of visual awareness. Participants received positive, negative, and neutral affect inductions and then completed a series of binocular rivalry trials in which a face (smiling, scowling, or neutral) was presented to one eye and a house to the other. The percepts “competed” for dominance in visual consciousness. We found, as predicted, that all faces (smiling, scowling, and neutral) were dominant for longer when perceivers experienced unpleasant affect compared to when they were in a neutral state (a social vigilance effect), although scowling faces increased their dominance when perceivers felt unpleasant (a relative negative congruence effect). Relatively speaking, smiling faces increased their dominance more when perceivers were experiencing pleasant affect (a positive congruence effect). These findings illustrate that the affective state of a perceiver serves as a context that influences the contents of consciousness.  相似文献

Anger is an intense and adaptive approach emotion that undergoes significant development during the toddler years. We assessed the expression of anger and the strategies toddlers use to regulate it in relation to maternal behavior and mental representations. Seventy-four toddlers were observed in three anger-eliciting paradigms: toy removal (TR), still-face (SF), and delayed gratification (DG). Anger expression and three clusters of regulatory behaviors were micro-coded: putative regulatory behaviors, attention manipulation, and play behaviors. Maternal relational style was coded for sensitivity and intrusiveness, and mental representations of the mother-child relationship were assessed for joy and anger. Children expressed the most anger during the TR, less during the SF, and minimally during the DG. Use of putative regulatory behaviors was highest during the SF, whereas during the TR children employed newly acquired skills, such as focused attention and substitutive play, in the service of anger regulation. Anger expression and regulation were differentially related to the negative and positive components in the mother's behavior and representations, and maternal intrusiveness moderated the relations between angry representations and the degree of child anger during the SF. Results are consistent with dynamic models of emotions and accord with perspectives that emphasize the role of sensitive parenting in facilitating emotion regulation.  相似文献
