This study investigated the relation between postural movement and upper-limb coordination stability. Adults produced bimanual circles using in-phase and anti-phase coordination patterns in time to an increasing rate metronome (i.e., movement-time instruction) in the horizontal (e.g., tabletop) and vertical (e.g., "wall" perpendicular to body) planes. All participants produced the instructed in- and anti-phase patterns. Coordination stability (i.e., SD of relative phase) was larger for anti-phase than in-phase patterns in both planes; however, anti-phase coordination stability was lower in the vertical plane than in the horizontal plane. Torso movement was larger during anti-phase coordination patterns in the horizontal plane, whereas it was larger during in-phase coordination patterns in the vertical plane. These results indicate that different orientations of the same task can produce different results for stability of coordination. This information may be important for performing and learning complex motor-coordination movements (e.g., playing musical instruments). 相似文献

Drug-associated cues are critical in reinstating the drug taking behavior even during prolonged abstinence and thus are thought to be a key factor to induce drug craving and to cause relapse. Amygdaloid complex has been known for its physiological function in mediating emotional experience storage and emotional cues-regulated memory retrieval. This study was undertaken to examine the role of basolateral nuclei of amygdala and the intracellular signaling molecule in drug cues-elicited cocaine memory retrieval. Systemic anisomycin treatment prior to the retrieval test abolished the cues-provoked cocaine conditioned place preference (CPP) memory. Likewise, a similar blockade of cues-provoked cocaine CPP performance was achieved by infusion of anisomycin and cycloheximide into the basolateral nuclei of amygdala before the test. Intra-amygdaloid infusion of H89, a protein kinase A inhibitor, or U0126, a MEK inhibitor, did not affect retrieval of the cues-elicited cocaine CPP memory. In contrast, intra-amygdaloid infusion of NPC 15437, a PKC inhibitor, abolished the cues-elicited cocaine CPP expression, while left the memory per se intact. Intra-amygdaloid infusion of NPC 15437 did not seem to affect locomotor activity or exert observable aversive effect. Taken together, our results suggest that activation of PKC signaling pathway and probably downstream de novo protein synthesis in the basolateral nuclei of amygdala is required for the cues-elicited cocaine memory performance. However, temporary inhibition of this signaling pathway does not seem to affect cocaine CPP memory per se. 相似文献

Research has taken a dim view of regulating emotions via expressive suppression. However, the impact of suppression may vary according to individuals’ interpersonal orientation. In two studies, we examined the effects of suppression under self-transcendent and self-interest orientations. Results revealed that (1) in everyday life, although dispositional suppression was related to lower psychological well-being, the costs associated with suppression were buffered among individuals with a self-transcendence orientation (Study 1); and (2) among individuals primed with a self-transcendence orientation, suppression of negative emotions in an interpersonal conflict situation led to lower levels of anger-related emotions and higher levels of perceived relational quality compared to emotional expression; however, among individuals primed with a self-interest orientation, suppression led to higher levels of anger-related emotions and lower levels of perceived relational quality compared to expression (Study 2). Together, results from the present study highlight the role of interpersonal orientation in moderating the effects of suppression on well-being. 相似文献

This research aims to explore the impacts of ad metaphors and goal orientation on the relationship between brand commitment and attitudes toward the competitor brands. Results show that prevention‐focused consumers with high brand commitment do not exhibit differentially favorable attitudes toward the competitor brands, regardless of ad metaphors. In contrast, prevention‐focused consumers with low brand commitment exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads. Moreover, promotion‐focused consumers exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads, regardless of brand commitment. 相似文献

While not a monolithic movement, ecofeminists are united in their conviction that there are important connections between the exploitation of both women and nature. They are internally divided, however, on the propriety of applying their theoretical claims and activist strategies across social contexts. This paper explores three debates within ecofeminism that largely turn on this universalist versus particularist tension: whether ecofeminist theorizing can adequately account for cultural variation; whether its common usage of essentialist rhetoric is productive or troubling; and whether resources for social activism could legitimately be culled from an assembly of heterogeneous and foreign sources. I conclude that the universalism of the women–nature connection can indeed be justified if perceived in multivalent ways, that “earthcare” or “ecomaternalist” discourse can be helpful in some contexts but harmful in others, and that selective retrieval of other cultures for the purposes of advocacy should not be ruled out as necessarily imperialistic or otherwise inappropriate. 相似文献
