This article proposes and tests a theoretical model articulating when and why differences in devaluation and avoidance of individuals with non-normative characteristics emerge between East Asian and Western cultural contexts. Four main studies examined this theoretical model. In a pilot study, relative to Americans, Koreans devalued a target individual with a non-normative characteristic, and in Study 1 the target’s efforts to forestall disruption of group processes eliminated the devaluation in Korea, with perceived selfishness mediating this process. In Study 2, Koreans, relative to Americans, devalued and avoided coworkers with non-normative characteristics, particularly when the non-normative characteristic was controllable. Study 3 further showed that perceived selfishness mediates this effect with a behavioral dependent variable. Study 4 tested the generalizability to positively valenced characteristics and found that Koreans (relative to Americans) also devalue individuals with positive characteristics at non-normative levels. Implications for individuals with non-normative characteristics, organizational diversity, and cross-cultural interaction are discussed. 相似文献

Research has systematically documented the negative effects of social exclusion, yet little is known about how these negative effects can be mitigated. Building on the approach-inhibition theory of power (Keltner, Gruenfeld, & Anderson, 2003), we examined the role of power in facilitating social connection following exclusion. Four experiments found that following exclusion, high power (relative to low power) individuals intend to socially connect more with others. Specifically, following exclusion, individuals primed with high power sought new social connections more than those primed with low power (Studies 1–4) or those receiving no power prime (Study 1). The intention to seek social connection as a function of power was limited to situations of exclusion, as it did not occur when individuals were included (Studies 3 and 4). Approach orientation mediates the effect of power on intentions to connect with others (Studies 2 and 4). 相似文献

The purpose of this investigation was to determine the effect of iris color on critical flicker frequency (CFF). CFF thresholds were obtained on 56 male subjects between the ages of 18 and 25 divided into three groups on the basis of iris color (blue, green, and brown). The results indicate that iris color is a statistically significant factor in the determination of CFF (p < .05), though it was emphasized that the effect may have been due to the correlation between iris color and other ocular pigmentation. The blue-eyed group received the highest mean CFF and the brown-eyed group the lowest mean CFF with the mean CFF threshold of the green-eyed group falling between these values. 相似文献

Abstract Ninety-nine participants were assigned to one of three experimental conditions in which they viewed an AIDS education videotape that systematically manipulated whether or not the educator would be perceived as responsible for HIV infection. Participants were administered pre and post-video affect measures, and an HlV/AIDS knowledge test after watching the video. Participants who viewed the speaker who acquired HIV through a blood transfusion (perceived not responsible) and those who viewed the speaker who did not reveal mode of acquisition (control) performed significantly better on the knowledge test compared to those who viewed the speaker who acquired HIV through unprotected sexual inttrcourse (perceived responsible). In addition. male participants in the perceived responsible condition reported a significant increase in sensation-sceking after viewing the video. Finally, females experienced a significantly greater increase in anxiety as a result of seeing the video than did males. Implications of these tindings for the design and implmentation of AIDS education programs were discussed. 相似文献

Establishing and maintaining connections with others is central to a fulfilling social life. In this respect, behavioral coordination provides one avenue by which interpersonal linkages can be formed. Drawing from the dynamical systems approach, the present research explored whether temporary interpersonal connections founded on coordinated behavior influence memory for self and others. To do so, we measured participants’ incidental recall of self and other-relevant information after a period of either in-phase or anti-phase interpersonal coordination. While participants in the less stable anti-phase condition demonstrated the typical memory advantage for self-related compared to other-related information, this effect was eliminated when participant and confederate movements displayed in-phase coordination. These results are discussed with respect to the interplay between the systems that support interpersonal synchrony and basic social-cognitive processing. 相似文献

This article describes an exercise developed for assessing trainee family therapists' practice at the end of a placement year in a manner consistent with the third‐order positioning the trainees were endeavouring to adopt in their practice. Evaluation by the trainees confirmed that the exercise had provided them with a significant opportunity to co‐construct with the supervisors their practice learning and future learning goals. 相似文献

We describe a compelling motion illusion elicited by a huge billboard placed along a street, depicting a building that contains strong perspective cues. When observers move fast along the opposite sidewalk, they perceive the depicted building as rotating in their direction of travel. This is a special case of the 'following', or 'pointing out of the picture', illusion that elicits a strong illusory motion percept. Here we discuss the cause of the illusory motion and suggest that the brain relies on the depicted perspective cues to infer a 3-D shape and a concomitant motion that is incompatible with the physical pictorial surface. 相似文献

The nucleus accumbens (NAc) plays a role in hedonic reactivity to taste stimuli. Learning can alter the hedonic valence of a given stimulus, and it remains unclear how the NAc encodes this shift. The present study examined whether the population response of NAc neurons to a taste stimulus is plastic using a conditioned taste aversion (CTA) paradigm. Electrophysiological and electromyographic (EMG) responses to intraoral infusions of a sucrose (0.3 M) solution were made in naïve rats (Day 1). Immediately following the session, half of the rats (n = 6; Paired) received an injection of lithium chloride (0.15 M; i.p.) to induce malaise and establish a CTA while the other half (n = 6; Unpaired) received a saline injection. Days later (Day 5), NAc recordings during infusions of sucrose were again made. Electrophysiological and EMG responses to sucrose did not differ between groups on Day 1. For both groups, the majority of sucrose responsive neurons exhibited a decrease in firing rate (77% and 71% for Paired and Unpaired, respectively). Following conditioning, in Paired rats, EMG responses were indicative of aversion. Moreover, the majority of responsive NAc neurons now exhibited an increase in firing rate (69%). Responses in Unpaired rats were unchanged by the experience. Thus, the NAc differentially encodes the hedonic value of the same stimulus based on learned associations.Our search for sustenance and pleasurable stimuli is often balanced by our desire to avoid punishment and harm. Similarly, neural systems responsible for generating approach behavior must be countered by signals that suppress approach behavior under contexts where approach is dangerous or maladaptive (Hoebel et al. 2007). The nucleus accumbens (NAc) is acutely involved in food intake and goal-directed, approach behavior. Pharmacological manipulations of the NAc promote food intake even in sated rats (Maldonado-Irizarry and Kelley 1995; Stratford and Kelley 1997). Lesions or inactivation of the NAc impair conditioned approach behavior (Cardinal et al. 2002; Blaiss and Janak 2009). Interestingly, drugs that lead to inhibition of select regions of the NAc increase positive hedonic responses to palatable taste solutions (Pecina and Berridge 2005). Recordings from individual NAc neurons have mirrored these findings. We and others have shown that consumption of palatable food stimuli is associated with decreases in the firing rate of the majority of responsive NAc neurons (Nicola et al. 2004b; Roitman et al. 2005; Taha and Fields 2005; Wheeler et al. 2008). In addition, decreases in NAc neural activity are associated with bouts of licking behavior for palatable stimuli (Taha and Fields 2006), and disruption of these decreases halt feeding bouts (Krause et al. 2010). Finally, decreases in NAc neural activity are associated with preferred locations previously paired with drug reward (German and Fields 2007). Thus, decreases in NAc activity appear to be closely linked to positive hedonic stimuli, stimuli that have been explicitly paired with them and behavioral approach.The NAc is also responsive to aversive stimuli (Carlezon and Thomas 2009; Levita et al. 2009). The delivery of aversive taste stimuli to rats is associated with increases in the firing rate of the majority of responsive NAc neurons (Roitman et al. 2005; Wheeler et al. 2008). In addition to responding to primary appetitive and aversive taste stimuli, NAc neurons develop responses to predictors of reward and aversion. Individual NAc neurons selectively encode cues that predict either appetitive (Roitman et al. 2005; Day et al. 2006) or aversive (Roitman et al. 2005) stimuli following purely Pavlovian conditioning or a combination of instrumental and Pavlovian conditioning (Setlow et al. 2003; Nicola et al. 2004a). NAc neurons come to encode departure from locations not associated with reward with the majority response being that of excitation (German and Fields 2007). Thus, NAc neurons appear to encode aversive stimuli and withdrawal behavior with increases in activity. These and other findings have led to the recent postulation that reward and aversion are differentially encoded by the activity of NAc neurons (Carlezon and Thomas 2009).Data supportive of the activity hypothesis (Carlezon and Thomas 2009) have been generated by the use of different stimuli to serve as appetitive or aversive primary or predictive stimuli. Thus, selective encoding could be biased by the sensory properties of each stimulus rather than their hedonic valence. When a novel, palatable taste is paired with visceral malaise, a Pavlovian association is made and a conditioned taste aversion (CTA) is established. Subsequent exposure to the once palatable stimulus is met with avoidance or aversion and rejection (Garcia et al. 1974; Schafe et al. 1995). Thus, the same taste stimulus can either be appetitive or aversive, depending on Pavlovian associations. Here, individual NAc neurons were recorded in rats (Paired) before (Day 1) and after a CTA (Day 5) was established and compared with rats that received equal exposure to the same stimuli but in an unpaired manner (Unpaired), and hence no CTA developed. Simultaneously, oro-motor behavior was characterized to provide an index of the associative strength of the taste stimulus. Using this paradigm, we determined that the population response of the NAc does indeed encode hedonic valence. 相似文献

This is the first study undertaken in the UK that investigates the notion of professional identity among practitioners who work with asylum seekers and refugees. Drawing on a social constructionist epistemology and a Foucauldian theoretical and methodological framework of power and discourse, I analysed extracts from semi-structured interviews that were conducted with eight specialist professionals who have worked with this population. The findings of this study suggest that the notion of professional identity among these practitioners envelops a social and political activist stance and a deep sense of commitment towards promoting social change within the wider community. Likewise, clinical work with refugees combines professional knowledge and values with a politicised involvement that fosters a psychosocial perspective on clients' distress and difficulties. 相似文献

The visual system has been suggested to integrate different views of an object in motion. We investigated differences in the way moving and static objects are represented by testing for priming effects to previously seen ("known") and novel object views. We showed priming effects for moving objects across image changes (e.g., mirror reversals, changes in size, and changes in polarity) but not over temporal delays. The opposite pattern of results was observed for objects presented statically; that is, static objects were primed over temporal delays but not across image changes. These results suggest that representations for moving objects are: (1) updated continuously across image changes, whereas static object representations generalize only across similar images, and (2) more short-lived than static object representations. These results suggest two distinct representational mechanisms: a static object mechanism rather spatially refined and permanent, possibly suited for visual recognition, and a motion-based object mechanism more temporary and less spatially refined, possibly suited for visual guidance of motor actions. 相似文献
