According to the Fr?hlich effect, observers perceive the initial position of a fast moving stimulus displaced in the direction of motion. On the basis of Kirschfeld and Kammer's as well as Fr?hlich's original assumption that metacontrast plays an important role in the emergence of the phenomenon, we predicted different amounts of misperception for stimulus enlargement compared to stimulus reduction. These basic predictions were confirmed in Experiment 1. In Experiment 2, we investigated whether an overestimation-bias might account for these results. But the overestimation of non-changing stimuli was too small to adequately explain the dissociation. In Experiment 3, we predicted and found different effects of the factor stimulus lightness on misperception in the enlargement and reduction condition. In Experiment 4, we showed that misperception in the enlargement condition is reduced when frames are used instead of filled stimuli, as in the earlier experiments. Results are discussed with respect to the original Fr?hlich effect.  相似文献

The study examined the association of exercise commitment with proneness to eating disorders in 50 physical education teachers who had been practicing various aerobic sports at least three times a week for at least 5 years. Significant coefficients were found between Commitment to Exercise Scale scores, the number of weekly training sessions, and scores on the Eating Disorders Inventory-2 scales measuring Maturity Fears, Social Insecurity, Perfectionism, and Asceticism. However, no relationship was found between the Commitment to Exercise Scale and the Eating Disorders Inventory-2 variables measuring anorexic tendencies (such as Drive for Thinness, Body Dissatisfaction, and Bulimia). Findings suggest the presence of some psychological factors common to both anorexic tendencies and excessive exercising but not complete overlap, so a rather more complex pattern of relationships appears to be mediated by sex and personality characteristics.  相似文献

When asked to indicate the starting position of a fast moving stimulus, observers do not indicate the actual starting position but a later position on the motion trajectory. This perceptual illusion is known as the “Fröhlich effect”. We present a neural model aimed at simulating this phenomenon based on feedforward and feedback connections. The basic simulation mechanisms seem to be compatible with the attentional and the motion extrapolation account. A comparison between simulated and empirical results showed that the model is capable of generating the same main effects as those found in the empirical data.  相似文献

Computers are increasingly present in education and make manyresources and activities available to teachers and pupils. Newpedagogical resources development is very interesting for both.Our digital library Summa Logicae is overtly involved in innovationand pedagogical systematization. It includes some software toolsfor teaching logic developed by computer science students, andin this article we present two of these tools. The MAFIA toolis especially attractive for first year students and helps themto understand the basic concepts of logic in an interactiveway using sematic tableaux. It also allows them to solve thecrazy cases in Mafia which their fellow students from previousyears proposed. The Modelos de Kripke tool, oriented to a moreadvanced level, serves for understanding the link between theproperties of the accessibility relation and the modal formulas,which is at the basis of the current developments of modal logic.  相似文献

This report presents findings for a set of dizygotic twins at age 4 years 9 months. The male was diagnosed as specifically language impaired. For both children, the left-right perisylvian configuration was atypical. Only the male's configuration was symmetrical, a finding in line with autopsy data reported for subjects with "developmental dyslexia" who also may have had a form of language impairment. In addition, the male had an atypical (L greater than R) configuration of the cerebral hemispheres, a finding not seen in his twin, or in a series of volunteers without a history of developmental language impairment. The in utero effects of gonadal hormones that may account for these findings are discussed.  相似文献

Insecure attachment has been hypothesized to be an important factor for understanding the experience of pain. Considering the Attachment-Diathesis Model of Chronic Pain developed by Meredith, Ownsworth, and Strong (2008), this cross-sectional study examines the relationship between attachment style, pain appraisal, and illness behavior. Two hundred healthy women recruited from community contexts completed a battery of self-report measures including the Short-form McGill Pain Questionnaire, Pain Catastrophizing Scale, Pain Anxiety Symptoms Scale-20, Pain Vigilance and Awareness Questionnaire, Illness Attitude Scales, Beck Anxiety Inventory, Beck Depression Inventory, and the Experiences in Close Relationships Questionnaire-Revised. The results showed that attachment anxiety was significantly correlated with pain catastrophizing, pain-related fear, depression, and illness behavior. However, attachment anxiety and avoidance were not associated with pain intensity. Attachment anxiety moderated the relationship between pain catastrophizing and illness behavior, and between pain hypervigilance and illness behavior. Pain catastrophizing and pain-related fear partially mediated the effect of attachment anxiety on illness behavior. The findings highlight potential contributions of attachment style and pain appraisal for explaining illness behavior. This study supports earlier reports and suggests the usefulness of assessing attachment style for early identification of people who might exhibit a high risk of dysfunctional responses to pain. Our findings also suggest that increasing people's insight about their attachment style and modifying some associated dysfunctional responses may be important in the treatment of chronic pain.  相似文献

This study addresses the links between distinct levels of marital conflict and mothers’ and fathers’ parenting stress and their associations with children’s adjustment. Using a sample of 358 Italian father–mother dyads with school–aged children, we computed a cluster analysis to identify distinct groups of families with different levels of interparental conflict. In each of the three groups identified (low, moderate, and high marital conflict), we conducted correlational and mediational analyses to explore the relationship between interparental conflict and children’s adjustment, the relationship between interparental conflict and maternal and paternal stress, and the potential mediating role of these components of maternal and paternal stress in the association between interparental conflict and children’s adjustment. We administered the R-CTS, PSI-SF, and CBCL to parents in order to assess marital conflict, maternal and paternal stress, and children’s behavioral problems; children completed the CPIC in order to evaluate their perceptions of interparental conflict. Results show that, in the high marital conflict group, levels of interparental conflict negatively affect children’s adjustment; moreover, the parent–child dysfunctional interaction component of maternal stress partially mediates the relationship between interparental discord and children’s internalizing behaviors, while the difficult child component of paternal stress fully mediates the effects of marital conflict on externalizing behaviors. In the moderate marital conflict group, levels of interparental conflict are correlated with the difficult child component of both maternal and paternal stress, while in the low marital conflict group, interparental conflict does not correlate with both maternal and paternal stress and children’s adjustment.  相似文献

The present study examined empathy and emotion dysregulation, two individual traits related to the perception and experience of others’ emotions, and the recognition of both spontaneous and standardized microexpressions of emotion. Ninety-three participants viewed a stimulus set of natural (spontaneous) microexpressions in addition to completing a standardized test of microexpression recognition ability, as well as completing questionnaires on empathy and emotion dysregulation. Results indicate that emotion dysregulation is associated with enhanced microexpression recognition, particularly recognition of anger microexpressions, but that this enhanced recognition was only observed for standardized microexpressions. Empathy was associated with increased recognition of anger microexpressions in the natural stimulus set only, and was not associated with overall microexpression recognition accuracy in either the natural stimulus set or the standardized test. The present findings inform understanding of intrapersonal affective traits in subtle emotion recognition, and theoretical and practical implications are discussed in both clinical and deception detection contexts.  相似文献
