Urban animals and birds in particular are able to cope with diverse novel threats in a city environment such as avoiding novel, unfamiliar predators. Predator avoidance often includes alarm signals that can be used also by hetero-specifics, which is mainly the case in mixed-species flocks. It can also occur when species do not form flocks but co-occur together. In this study we tested whether urban crows use alarm calls of conspecifics and hetero-specifics (jackdaws, Corvus monedula) differently in a predator and a non-predator context with partly novel and unfamiliar zoo animal species. Birds were tested at the Tiergarten Schönbrunn in the city of Vienna by playing back con- and hetero-specific alarm calls and control stimuli (great tit song and no stimuli) at predator (wolf, polar bear) and non-predator (eland antelope and cranes, peccaries) enclosures. We recorded responses of crows as the percentage of birds flying away after hearing the playback (out of those present before the playback) and as the number of vocalizations given by the present birds. A significantly higher percentage of crows flew away after hearing either con- or hetero-specific alarm calls, but it did not significantly differ between the predator and the non-predator context. Crows treated jackdaw calls just as crow calls, indicating that they make proper use of hetero-specific alarm calls. Responding similarly in both contexts may suggest that the crows were uncertain about the threat a particular zoo animal represents and were generally cautious. In the predator context, however, a high percentage of crows also flew away upon hearing the great tit control song which suggests that they may still evaluate those species which occasionally killed crows as more dangerous and respond to any conspicuous sound. 相似文献

Individuals with obesity in Western societies often face weight-related stigmatization and social exclusion. Recurrent exposure to prejudice and negative social feedback alters one’s behavior in future social interactions. In this study, we aimed to investigate autonomic nervous system and affective responses to social interactions in individuals with obesity. Women and men with (n = 56) and without (n = 56) obesity participated in episodes of social inclusion and social exclusion using a virtual ball-tossing game. During the experiment, heart rate was measured and parasympathetic activity (overall high-frequency power and event-related cardiac slowing) was analyzed. Our results show that in novel social interactions, women with obesity, relative to the other groups, exhibited the strongest increase in parasympathetic activity. Furthermore, parasympathetic activity was related to a more negative body image in individuals with obesity, but not in lean individuals. Additionally, women with obesity reported a stronger decrease in mood after social exclusion than did the other participants. Our results demonstrate influences of objective and subjective bodily characteristics on parasympathetic cardio-regulation during social interactions. In particular, they show behavioral and physiological alterations during social interactions in women with obesity. 相似文献

Attention deficit hyperactive disorder (ADHD) is associated with elevated levels of substance abuse, but the cognitive linkages
involved have been little explored. The present study builds upon earlier work showing that more gestalt, as opposed to feature-intensive,
styles of processing are conductive to substance abuse, especially in those with ADHD symptoms. The work reported here indicates
that a protective factor against substance abuse may lie in relatively efficient heuristic processing, especially synthetic
or inferential heuristic processing, but further demonstrates that those with ADHD symptoms tend to have poorer abilities
in this regard, even at the subclinical, nondiagnosed level. Results are discussed in terms of the gestalt/featureintensive
processing theory of cognition. 相似文献

Although many individuals report being friends with their ex-romantic partners (Wilmot, Carbaugh, & Baxter, 1985), the literature regarding post-romantic friendships is very limited. We investigated whether satisfaction in the dissolved romantic relationship could predict post-romantic friendships and friendship maintenance. We found that the more satisfied individuals were during the dissolved romance, the more likely they were to remain friends and the more likely they were to engage in friendship maintenance behaviors. We also found that friendship maintenance fully mediated the association between past romantic satisfaction and current friendship satisfaction. 相似文献

A substantial proportion of Borderline Personality Disorder (BPD) patients respond by a marked decrease of psychopathology when treated with Dialectical Behavioral Therapy (DBT). To further enhance the rate of DBT-response, it is useful to identify characteristics related to unsatisfactory response. As DBT relies on emotional learning, we explored whether dissociation-which is known to interfere with learning- predicts poor response to DBT. Fifty-seven Borderline Personality Disorder (BPD) patients (DSM-IV) were prospectively observed during a three-month inpatient DBT program. Pre-post improvements in general psychopathology (SCL-90-R) were predicted from baseline scores of the Dissociative Experiences Scale (DES) by regression models accounting for baseline psychopathology. High DES-scores were related to poor pre-post improvement (β = -0.017 ± 0.006, p = 0.008). The data yielded no evidence that some facets of dissociation are more important in predicting DBT-response than others. The results suggest that dissociation in borderline-patients should be closely monitored and targeted during DBT. At this stage, research on treatment of dissociation (e.g., specific skills training) is warranted. 相似文献

It is well documented that in the first year after birth, infants are able to identify self-performed actions. This ability has been regarded as the basis of conscious self-perception. However, it is not yet known whether infants are also sensitive to aspects of the self when they cannot control the sensory feedback by means of self-performed actions. Therefore, we investigated the contribution of visual–tactile contingency to self-perception in infants. In Experiment 1, 7- and 10-month-olds were presented with two video displays of lifelike baby doll legs. The infant’s left leg was stroked contingently with only one of the video displays. The results showed that 7- and 10-month-olds looked significantly longer at the contingent display than at the non-contingent display. Experiment 2 was conducted to investigate the role of morphological characteristics in contingency detection. Ten-month-olds were presented with video displays of two neutral objects (i.e., oblong wooden blocks of approximately the same size as the doll legs) being stroked in the same way as in Experiment 1. No preference was found for either the contingent or the non-contingent display but our results confirm a significant decrease in looking time to the contingent display compared to Experiment 1. These results indicate that detection of visual–tactile contingency as one important aspect of self-perception is present very early in ontogeny. Furthermore, this ability appears to be limited to the perception of objects that strongly resemble the infant’s body, suggesting an early sensitivity to the morphology of one’s own body. 相似文献

This study investigated age-related differences between younger (M = 25.52 years) and older (M = 70.51 years) adults in avoidance motivation and the influence of avoidance motivation on gaze preferences for happy, neutral, and angry faces. In line with the hypothesis of reduced negativity effect later in life, older adults avoided angry faces and (to a lesser degree) preferred happy faces more than younger adults did. This effect cannot be explained by age-related changes in dispositional motivation. Irrespective of age, avoidance motivation predicted gaze behavior towards emotional faces. The study demonstrates the importance of interindividual differences beyond young adulthood. 相似文献

This article critically reflects on some of the themes and assumptions at stake in the “transracialism” controversy, and connects them to important works in critical race theory: namely Rey Chow's notion of “coercive mimeticism” and Sara Ahmed's critique of white liberal multiculturalism. It argues that the analytic account of “race” that Tuvel draws upon in her article—Sally Haslanger's—is politically problematic, both on its own terms and in light of broader reflections on racialized and gendered power relations. In particular, I critique Haslanger's assumption that all racial identities exist on the same conceptual plane: that a single variable definition of “race” can be applied to any particular racialized group—including white and nonwhite racial identities. This erases racialized power relations, especially where, in liberal “multicultural” nations, whiteness constitutes the implied standard against which an appearance of “racial difference” is conjured. Finally, I extend my argument to the issue of treating “race” and gender analogously. Rejecting this move, I propose an alternative way of conceptualizing these as analytically distinct, yet constitutively interdependent, phenomena. In order to situate the debate historically, I consider an example of “racial transgression” from twentieth‐century China. 相似文献

As the number of political scandals rises, we examined the circumstances that might influence how a politician would be judged as a result of a scandal. Specifically, we hypothesized that ingroup bias theory and shifting standards theory would produce different patterns of judgements. In two studies, we found support for the ingroup bias theory, such that participants rated the fictitious politician’s public approval and perceived character as higher if the politician was a member of their own political party (i.e. their ingroup) than if the politician was a member of the another political party (i.e. their outgroup). These results may explain, in part, why people may judge politicians involved in scandal more or less harshly depending on whether they are an ingroup member or outgroup member. 相似文献

This study examined social-emotional and cognitive factors in relation to eating disorder symptoms in 84 female undergraduates.
Sensitivity to criticism and rejection-sensitivity related to each other and to appearance-related sensitivity. Although both
interpersonal and appearance sensitivity related to a drive for thinness, appearance sensitivity had the stronger relationship.
Interpersonal sensitivity was significantly correlated with expectancies that dieting and thinness lead to overgeneralized
self-improvement, but not with eating expectancies. After controlling for body mass index, interpersonal sensitivity, and
appearance sensitivity, dieting/thinness expectancies were related to drive for thinness, and expectancies that eating helps
to manage negative affect were related to symptoms of bulimia. Findings are discussed in terms of the potential role that
interpersonal sensitivity and eating-related expectancies may play in the development and maintenance of eating disorders,
as well as intervention approaches.
