- Online auctions have grown in popularity since the inception of eBay in 1995. Yet despite the phenomenal growth, little is understood about the individual and collective motivations of consumers that lead to higher bids and ultimately, higher profits. This research reframes auction theory in terms of consumer behavior theory and uses observational data to assess bidder‐generated behavior in response to seller‐generated decisions. Results suggest that an increased number of visual cues (pictures) influences bids placed early in the auction and that those early bids generate activity among other bidders, subsequently resulting in higher winning bids. In addition, our findings indicate that the starting price, as determined by the seller, also impacts the final winning bid. Research and seller implications are offered, as are future directions for research in studying this still new phenomenon.

Infant bilingualism offers a unique opportunity to study the relative effects of language experience and maturation on brain development, with each child serving as his or her own control. Event-related potentials (ERPs) to words were examined in 19- to 22-month-old English-Spanish bilingual toddlers. The children's dominant vs. nondominant languages elicited different patterns of neural activity in the lateral asymmetry of an early positive component (P100), and the latencies and distributions of ERP differences to known vs. unknown words from 200-400 and 400-600 ms. ERP effects also differed for 'high' and 'low' vocabulary groups based on total conceptual vocabulary scores. The results indicate that the organization of language-relevant brain activity is linked to experience with language rather than brain maturation. 相似文献

We investigated the role of response selection in sequence learning in the serial reaction time (SRT) task, by manipulating stimulus-response compatibility. Under conditions in which other types of learning, like perceptual, response-based, and response-effect learning, were unaffected, sequence learning was better with an incompatible than with a compatible stimulus-response mapping. Stimulus discriminability, on the other hand, had no influence on the amount of sequence learning. This indicates that the compatibility effects cannot be accounted for by a different level of task difficulty. Relating our results to the dimensional overlap model (Kornblum, Hasbroucq, & Osman, 1990), which assumes that incompatible stimulus-response mappings require more controlled response selection than do compatible stimulus-response mapping, we suggest that sequence learning in the SRT task is particularly effective when response selection occurs in a controlled way. 相似文献

This experiment investigated whether properties of the text being read affect binocular coordination of the eyes during reading. Readers' binocular eye movements were recorded while they read sentences that contained high- and low-frequency words. In addition, half of the sentences were presented in normal case, and half were presented in alternating case (i.e., AlTeRnAtInG cAsE). Past research has suggested that the visual system tolerates less binocular fixation disparity with alternating than with normal case (Heller & Radach, 1999). While both word frequency and alternating case produced large effects on fixation durations on the target word, neither manipulation affected the magnitude of fixation disparity. It is concluded that linguistic and visual properties of the text being read do not influence binocular coordination of the eyes during reading. Additional analyses also showed no difference in fixation disparity between reading and a nonlinguistic task. Implications of these results for split-fovea models of reading are discussed. 相似文献

Conflicts arising from the work setting have remained a neglected issue in psychotherapy. To address this, the present study investigated the effectiveness of a manualized focal group treatment for psychotherapeutic inpatients suffering from vocational strains and conflicts and identified predictors of outcome. Cohorts of patients were assigned either to a treatment (N=144) or control condition (N=135). The group therapy intervention was found to be highly accepted by participants who were also more optimistic about returning to work and more favorable in their evaluations of treatment than patients in the treatment-as-usual condition. Group climate was found to be a predictor of favorable outcome. The findings suggest that a group therapy intervention with a strong emphasis on motivations and attitudes about work may be particularly suitable to deal with vocational conflicts and strains. 相似文献

The social, intellectual, and moral movement known as multiculturalism has been enormously influential in psychology. Its ability to reshape psychology has been due to its ethical force, which derives from the attractiveness of its aims of inclusion, social justice, and mutual respect. The cultivation of cultural competence, presented as a developmental process of acquiring self-awareness, cultural knowledge, and skills, is an important emphasis in the multicultural literature. The authors place the cultural competence literature in dialogue with virtue ethics (a contemporary ethical theory derived from Aristotle) to develop a rich and illuminating way for psychologists to understand and embody the personal self-examination, commitment, and transformation required for learning and practicing in a culturally competent manner. According to virtue ethics, multiculturalism can be seen as the pursuit of worthwhile goals that require personal strengths or virtues, knowledge, consistent actions, proper motivation, and practical wisdom. The authors term the virtue of multiculturalism openness to the other and conclude by describing how attention to cultural matters also transforms virtue ethics in important and necessary ways. 相似文献

Moderate versus light pressure massage therapy leads to greater weight gain in preterm infants 总被引:2,自引:0,他引:2
Field T Diego MA Hernandez-Reif M Deeds O Figuereido B 《Infant behavior & development》2006,29(4):574-578
Sixty-eight preterm infants (M GA = 30 weeks) were randomly assigned to a moderate or to a light pressure massage therapy group to receive 15 massages three times per day for 5 days. Behavior state, stress behaviors and heart rate were recorded for 15 min before and during the first 15-min therapy session. Weight gain was recorded over the 5-day therapy period. The moderate versus light pressure massage group gained significantly more weight per day. During the behavior observations the moderate versus light pressure massage group showed significantly lower increases from the pre-session to the session recording on: (1) active sleep; (2) fussing; (3) crying; (4) movement; and (5) stress behavior (hiccupping). They also showed a smaller decrease in deep sleep, a greater decrease in heart rate and a greater increase in vagal tone. Thus, the moderate pressure massage therapy group appeared to be more relaxed and less aroused than the light pressure massage group which may have contributed to the greater weight gain of the moderate pressure massage therapy group. 相似文献
