During reading, participants generally move their eyes rightward on the line. A number of eye movements, called regressions, are made leftward, to words that have already been fixated. In the present study, we investigated the role of verbal memory during regressions. In Experiment 1, participants were asked to read sentences for comprehension. After reading, they were asked to make a regression to a target word presented auditorily. The results revealed that their regressions were guided by memory, as they differed from those of a control group who did not read the sentences. The role of verbal memory during regressions was then investigated by combining the reading task with articulatory suppression (Exps. 2 and 3). The results showed that articulatory suppression affected the size and the accuracy of the initial regression but had a minimal effect on corrective saccades. This suggests that verbal memory plays an important role in determining the location of the initial saccade during regressions.  相似文献

Depression during the prenatal and postpartum periods is associated with poor maternal, perinatal and child outcomes. This study examines the effectiveness of a culturally and linguistically tailored, social support-based, healthy lifestyle intervention led by trained community health workers in reducing depressive symptoms among pregnant and early postpartum Latinas. A sample of 275 pregnant Latinas was randomized to the Healthy MOMs Healthy Lifestyle Intervention (MOMs) or the Healthy Pregnancy Education (control) group. More than one-third of participants were at risk for depression at baseline. MOMs participants were less likely than control group participants to be at risk for depression at follow-up. Between baseline and 6 weeks postpartum, MOMs participants experienced a significant decline in depressive symptoms; control participants experienced a marginally significant decline. For MOMs participants, most of this decline occurred during the pregnancy intervention period, a time when no change occurred for control participants. The change in depressive symptoms during this period was greater among MOMs than control participants (“intervention effect”). From baseline to postpartum, there was a significant intervention effect among non-English-speaking women only. These findings provide evidence that a community-planned, culturally tailored healthy lifestyle intervention led by community health workers can reduce depressive symptoms among pregnant, Spanish-speaking Latinas.  相似文献

In differentiation of early and mature shame, the phenomenological content of shame changes with the development of a stable self-state. In this hypothesis, early shame refers to a person's dependence upon mirroring himself and in being mirrored by an outer object, while mature shame refers to introspection and self-reflection. From a developmental psychological point of view, the connection between self-development and mirroring is expounded. Mirroring is defined as a psychic dialectic process between the inner psychic reality and the outer reality. Early shame is connected to dyadic mirroring, which refers to attachment and empathy. Mature shame is connected to triadic mirroring, which refers to separation and reflection. Early shame emerges from discrepancies between the infant's expectations of a complementary affective response and the mother's response, and is defined as an early marker of differences in the mother/infant unit. It is argued that early shame in smaller ‘doses’ has a regulating function on self-development by maintaining the psychic dialectic process, while in larger ‘doses’, it has a disturbing effect on the self-development, resulting in pathological shame. In the therapeutic process, early shame appears as shame scenarios illustrated in the text by a clinical vignette.  相似文献

The ability to recognize others’ facial expressions is critical to the social communication of affective states. The present work examined how transient states of high physiological arousal during aerobic exercise influence recognizing and rating morphed facial expressions. Participants exercised at either a low or high work rate. While exercising and then during cool-down and rest periods, participants performed a version of the morphed faces task that involved animated faces changing into or away from five target affective states (happy, surprise, sadness, anger, and disgust); they were asked to stop the animation when the face first corresponded to a target state, and rate its emotional intensity. Results demonstrated no differences in animation stop data, but overall lower ratings of perceived emotion intensity during high versus low work rate exercise; these effects dissipated through cool-down and rest periods. Results highlight important interactions between physiological states and processing emotional information.  相似文献

With the Appraisal Tendency Framework, it has been established that (un)certainty appraisals associated with incidental emotions trigger the kind of information processing to cope with situation. We tested the impact of (un)certainty-associated emotions on a sequential task, the Iowa Gambling Task. In this task, intuitive processing is necessary to lead participants to rely on emotional cues arising from previous decisions and to making advantageous decisions. We predicted that certainty-associated emotions would engage participants in intuitive processing, whereas uncertainty-associated emotions would engage them in deliberative processing and lead them to make disadvantageous decisions. As expected, we observed in two distinct experiments, that participants induced to feel uncertainty (fear, sadness) were found to decide less advantageously than participants induced to feel certainty (anger, happiness, disgust).  相似文献

In this study we investigated how perception of the eye expression in a face is influenced by the mouth expression, even when only the eyes are directly looked at. The same eyes appeared in a face with either an incongruent smiling, angry, or sad mouth, a congruent mouth, or no mouth. Attention was directed to the eyes by means of cueing and there were no fixations on the mouth. Participants evaluated whether the eyes were happy (or angry, or sad) or not. Results indicated that the smile biased the evaluation of the eyes towards happiness to a greater extent than an angry or a sad mouth did towards anger or sadness. The smiling mouth was also more visually salient than the angry and the sad mouths. We conclude that the role of the eyes as a “window” to a person’s emotional and motivational state is constrained and distorted by the configural projection of an expressive mouth, and that this effect is enhanced by the high visual saliency of the smile.  相似文献

Observing a person in need usually provokes a compound and dynamic emotional experience made up of empathy and personal distress which, in turn, may influence helping behavior. As the exclusive use of rating scales to measure these two emotions does not permit the analysis of their concurrent evolution, we added the analogical emotional scale (AES) in order to measure how these two emotions evolve throughout the emotional experience, from its onset to its conclusion. Therefore, in two studies, the concurrence of empathy and personal distress was induced, both rating scales and AES were used, and participants were given an unexpected opportunity to help. Two effects were found. First, the helping behavior was lower when personal distress prevailed over empathy at the end of the experience (Studies 1 and 2). Second, this “end” effect was coherent with the nature of the different motives evoked by personal distress and empathy—directed to increasing either one’s own welfare (egoistic) or the victim’s welfare (altruism) (Study 2). These results support the usefulness of combining the rating scales and the AES for gaining a better understanding of the nature and behavioral consequences of complex, compound and dynamic emotional experiences.  相似文献

Emotional interference on behavior is commonly observed when task-irrelevant negative stimuli appear before behavioral targets. One explanation postulates that affect-laden stimuli readily capture attention, interfering with the processing of the upcoming target. Emotional stimuli might also preactivate motor programs incompatible with the demanded response. Using a cued go/no-go procedure we showed that task-irrelevant unpleasant stimuli cause interference or facilitation depending on their onset asynchrony relative to the target. We observed interference with short (200 ms) stimulus-target asynchronies and facilitation for longer ones (600 ms), both for key press (Experiment 1) and key release (Experiment 2) responses. The interference effect is compatible with an attentional explanation, but the behavioral facilitation is hard to accommodate within either attentional or motor accounts. This interference-facilitation pattern can be explained assuming that once the attentional effect subsides, emotional processing may enhance the perceptual processing of the stimuli, or lower the decision threshold, thereby facilitating the response selection process.  相似文献

Although achievement goal and expectancy-value theories are both dominant in the achievement motivation literature, the relation between goals and expectancy-value variables in predicting achievement-related behaviors remains unclear. The present study evaluated the empirical validity of four contrasting theoretical conceptions which posit that (1) goals and expectancy-value variables are independent predictors of achievement-related outcomes (2) goals predict expectancy-values, (3) goals mediate the relation between expectancies and task-values, and (4) goals partially mediate the relation between expectancy-values and achievement outcomes, in predicting course performance, career intentions and academic aspirations. Path models evaluating these conceptions were tested separately in mathematics and language arts domains among 697 6th and 8th grade students. Results supported the fourth theoretical approach suggesting that expectancy-value variables predict achievement-related outcomes both directly and indirectly through achievement goals. These findings provide insight about the relation between expectancy-value and achievement goal theories and highlight their complementary role in predicting achievement behaviors.  相似文献
