- 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.

Three experiments are reported, which examine whether face naming is vulnerable to semantic competition in a similar way to object naming. Previous experiments with object naming have shown that a related prime picture presented 3 trials before a target picture results in an increase in error rate and naming latencies when compared to unrelated prime conditions. The experiments here use the same paradigm, with errors as the main dependent variable. In Experiment 1, the prime and target faces were from the same occupational category (e.g., politicians, actors), and in Experiment 2, the primes and target faces were also associated to each other. In Experiment 3, the prime was presented as a name to be read aloud. Unrelated filler stimuli intervened between prime and target. In all experiments, there was a reduction in target-naming errors in the related conditions, and in Experiment 3 this was shown to be largely a reduction in naming failures. The results suggest that related name representations for famous people are not activated in parallel and in competition, and that there is some evidence for a relatively long lasting facilitatory effect. These results require some modification to any serial account of face naming to differentiate it from the generally well-established serial account of object naming. 相似文献

diagrams are powerful tools for comprehension and problem solving in diverse contexts. Two studies examined the structural properties of (i.e., applicability conditions for) three interrelated spatial diagrams—hierarchies, matrices, and networks. College students from two groups with distinct educational backgrounds and learning histories—advanced computer science students and representative undergraduates—rated the diagnosticity of the hypothesized applicability conditions for each of the 3 diagrams. The results validated 24-26 of the 30 hypothesized applicability conditions and provided evidence regarding the relative importance, or diagnosticity, of the validated properties for each type of diagram. A different set of properties was identified as most highly diagnostic for each type of diagram, indicating that the three spatial diagrams are optimized to serve different representational functions: The matrix stores static information about the kind of relation that exists between pairs of items in different sets, the network conveys dynamic information by showing the local connections and global routes connecting the items being represented, and the hierarchy depicts a rigid structure of power or precedence relations among items. The quantitative and qualitative differences in representational knowledge due to educational background are discussed. 相似文献

The effects of replacing core subtests with supplementary subtests on composite score reliabilities were evaluated for the WISC-IV Indexes and Full Scale IQ. When Wechsler's guidelines are followed, i.e., only one substitution for each Index; no more than two substitutions from different Indexes when assessing the Full Scale IQ, summary score reliabilities remain high, and measurement error, as defined by confidence intervals around obtained scores, never increases by more than 1 index score point. In three instances, substitution of a supplementary subtest for a core subtest actually increased the reliabilities and decreased the amount of associated measurement error. 相似文献

The current study investigated a behavior-analytic treatment, functional analytic psychotherapy (FAP), for outpatient depression utilizing two single-subject A/A+B designs. The baseline condition was cognitive behavioral therapy. Results demonstrated treatment success in 1 client after the addition of FAP and treatment failure in the 2nd. This study highlights the challenges in measuring treatment progress and outcome idiographically in this population. 相似文献

Sex-specific differences in olfactory sensitivity for putative human pheromones in nonhuman primates
Laska M Wieser A Salazar LT 《Journal of comparative psychology (Washington, D.C. : 1983)》2006,120(2):106-112
In humans, the volatile C19-steroids androsta-4,16-dien-3-one (AND) and estra-1,3,5(10),16-tetraen-3-ol (EST) have been shown to modulate autonomic nervous system responses, and to cause hypothalamic activation in a gender-specific manner. Using two conditioning paradigms, the authors here show that pigtail macaques and squirrel monkeys of both sexes were able to detect AND and EST at concentrations in the micromolar and mM range, respectively. Male and female spider monkeys, in contrast, differed markedly in their sensitivity to these two odorous steroids, with males not showing any behavioral responses to the highest concentrations of AND tested and females not responding to the highest concentrations of EST. These data provide the first examples of sex-specific bimodal distributions of olfactory sensitivity in a nonhuman primate species. 相似文献

This study examined the ability of the M-FAST to differentiate a group of undergraduate students simulating one of four DSM-IV diagnoses (n = 190; schizophrenia, major depressive disorder, bipolar disorder, and posttraumatic stress disorder) and a clinical comparison sample drawn from previous M-FAST studies comprising individuals with the same diagnosis (n = 142). Across all diagnostic conditions, the simulators obtained higher M-FAST total scores than the clinical comparisons, and the rare combinations scale was equal or superior to the total score at differentiating the groups. The M-FAST was most efficient at distinguishing feigned from bona fide schizophrenia. Although the internal consistency of the total score was high (alpha = 0.88), inter-item correlations were lower than values reported in previous research. Lastly, given the importance of base rate considerations in the evaluation of diagnostic instruments, it was notable that the M-FAST was able to identify malingerers even at relatively low base rates. 相似文献

We examined whether dispositional optimism and pessimism (overall LOT-R and optimism and pessimism component scores) of 694 adults aged 24 and 27 were associated with socioeconomic status (SES) measured concurrently and in childhood at ages 3 and 6. SES measures included education, occupational status and unemployment, and income. Concurrent adulthood SES was associated with the overall LOT-R and optimism and the pessimism component scores. Childhood family SES predicted overall LOT-R and pessimism component scores, even after controlling statistically for the adulthood SES. Social mobility between SES of family of origin and current SES also influenced the scores. The current findings suggest that the foundation of dispositional optimism and pessimism is related to early SES of the family. 相似文献
