Adaptation can optimize information processing by allowing the visual system to always adjust to the environment. However, only a few studies have investigated how the visual system makes adjustments to repeatedly occurring changes in the input, still less about the related neural mechanism. Our previous study found that contrast adaptation attenuated after multiple daily sessions of repeated adaptation, which was explained by the habituation of either the adapter’s effective strength or the adaptation mechanisms. To examine the former hypothesis, in the (...) present study we used the frequency tagging technique to measure the adapter-elicited steady-state visual evoked potential amplitudes. Participants repeatedly adapted to the same contrast adapter in a top-up manner for six continuous days, which was called training of adaptation. The behavioral adaptation effect and SSVEP response to the trained adapter and an untrained control adapter were measured before and after training. The psychophysical results showed that the effect of adaptation in the trained condition significantly reduced after training, replicating our previous finding. Contradicting the prediction of the hypothesis that repeated adaptation attenuated the effective strength of the adapter, the SSVEP amplitude was unchanged after training, which was further confirmed by an equivalence test. Taken together, the results challenge the account of habituation of adapter in repeated adaptation, while leaving the account of habituation of adaptation mechanism to be tested. (shrink)

Ao dai is a typical long dress of Viet Nam used to be worn by both men and women of the Viet and other ethnic peoples. In her shaping and development history, Viet Nam became a place that converged various cultural flows such as the Vietnamese indigenous culture and that of the Chinese, Champa and Indian etc. To the end of the 19th century, especially the 20th, Viet Nam continued to be influenced by the French culture and the American ways (...) of living. The acceptance of cultures from various nationalities and communities from the North to South, East to West made it possible for the Vietnamese fashion designers to harmonize all into an Ao dai for the Vietnamese women. This article will synthesize and analyze three renovation movements of Ao dai in the 20th century. It also discusses about these processes and introduces typical innovators whose contribution has created the Ao dai as it is today, a traditional dress that represents history of the Vietnamese culture, aesthetic sense, art and vitality.

Cognition and emotion exert a powerful influence on human behavior. Based on cognitive psychology and organizational behavior theory, this paper examines the role of cognition and emotion in participative budgeting and corporate performance using a questionnaire survey. The questionnaires were sent to 345 listed companies in China. The results support the hypothesis that human cognition and emotion have a positive moderating effect on the relationship between participative budgeting and corporate performance. Cognition and emotion can promote the effect of participative budgeting (...) on corporate performance. Furthermore, according to the theory of artificial intelligence, this paper designs an AI-based cognition and emotion identification system. This system can help managers identify the budget participants’ cognitive and emotional states and undertake the interventions necessary to improving corporate performance. (shrink)
