Whether the cognitive competences of monkeys and apes are rather similar or whether the larger-brained apes outperform monkeys in cognitive experiments is a highly debated topic. Direct comparative analyses are therefore essential to examine similarities and differences among species. We here compared six primate species, including humans, chimpanzees, bonobos, gorillas (great apes), olive baboons, and long-tailed macaques (Old World monkeys) in a task on fine-grained size discrimination. Except for gorillas, subjects of all taxa (i.e. humans, apes, and monkeys) were able to discriminate three-dimensional cubes with a volume difference of only 10 % (i.e. cubes of 50 and 48 mm side length) and performed only slightly worse when the cubes were presented successively. The minimal size discriminated declined further with increasing time delay between presentations of the cubes, highlighting the difficulty to memorize exact size differences. The results suggest that differences in brain size, as a proxy for general cognitive abilities, did not account for variation in performance, but that differential socio-ecological pressures may better explain species differences. Our study highlights the fact that differences in cognitive abilities do not always map neatly onto phylogenetic relationships and that in a number of cognitive experiments monkeys do not fare significantly worse than apes, casting doubt on the assumption that larger brains per se confer an advantage in such kinds of tests. 相似文献

In the current study we extend previous findings on the shooter bias toward targets with Arab ethnicity. In an adapted shooter task, we presented stereotypically oriental-looking targets without explicit symbols of Islam (e.g., a turban) and additionally tested if presenting a “harmless” companion dog, together with Arab versus White targets, would affect the shooter bias. Participants responded faster and made fewer errors for armed Arab than for armed White targets. Moreover, compared to the “neutral” no dog condition, the presence of a dog triggered fewer false alarms for White than for Arab targets and slowed down (correct) responses in general. Implications and potential underlying mechanisms are discussed. 相似文献

Online brand communities can serve as a crucial information source about a product-harm crisis and allow consumers to seek information from others and share their opinions in a social dynamic environment. The role of an online brand community in shaping consumer responses following such a crisis nevertheless remains under-researched. Drawing from attribution theory, this research explores the dynamic and holistic consumer journey in online brand communities following a product-harm crisis, specifically examining consumer attribution as the key mechanism and consumers' decision to forgive the brand as the outcome response. This research includes two studies. First, a netnographic pilot study is conducted to provide real-world evidence for the research phenomenon and to explore consumer responses within the natural setting of an online brand community. Second, the main study uses an interpretivist epistemological approach to track the unfolding process and capture the evolution of consumer attribution and forgiveness. The results show the social nature of attribution as members engage with others in online brand communities, seeking and verifying information, sensemaking and forming opinions. The findings make theoretical contributions to the literature on attribution and product-harm crisis. The findings from the research also help brands make informed decisions on crisis management strategies. 相似文献
