What does (AI) tool predict immediate emotion mean?Psychologists indicate that immediate emotions, by contrast, are experienced at the moment of choice and fall into one of two categories. Integral emotion, like expected emotions, arise from thinking about the consequences of one's decision, but " integral emotion", unlike expected emotions are experienced at the moment of choice. Such as purchase stock case, the share buyer might experience immediate fear at the thought of the stock's losing value. " Incidental emotions" are also experienced at the moment of choice, such as a consumer predicts the product or service price whether it will be risen up or fallen down. If he/she feels the product or service price will fall down after next month and he/she will choose to buy the product or consume the service. But consequently, after next month, the product or service's price won't fall down absolutely. Then, he/she will have incidental emotion to influence whom to choose whether he/she ought buy the product or consume the service, due to the product or service price is not still fall down. Otherwise, he/she is fear the product or service will not fall down in short term. Even, it will increase price later. Hence, whose incidental emotion will have possible to influence whom to choose to buy the product or consume the service after one month, if the product or service's price is still not increased absolutely. So, (AI) tool can be attempted to apply to predict when the product price ought need to be raised or fallen down in order to attract consumers to choose to buy the manufacturers' product in different period.Economists indicate utility an individual consumption with an outcome might arise from a prediction of emotion: For example, a dinner eater might choose a higher utility to an Italian restaurant dinner than a French restaurant dinner because who anticipates being happier at the former, even the former's dinner price is higher than the French restaurant. So, such as this restaurant dinner case, if one (AI) tool can assist the French restaurant owner to find what factor(S) cause(S) the dinner consumers do not choose to go to its restaurant to eat its food, e.g. high price factor, bad taste factor, bad wait service performance factor, bad cooker's cooking skill factor, poor advertisement promotion factor, poor familiar factor, poor location or poor eating environment etc. different factors. Then, the French restaurant owner can find methods to avoid the bad factor(S) cause(S) many dinner consumers do not choose to go to whose French restaurant to eat dinner more easily.The question is that whether the positive emotion factor can influence the consumer changes whose mind to choose to consume the more expensive service or buy the more expensive product. To answer this question. it depends on whether the consumer has an imperfect understanding of whose own tastes or the consumer has a perfect understanding of whose own tastes to the product or the service.It means the consumer will choose to buy the product or consume the service, even it's price is higher than other general similar products or services if who has a perfect understanding of whose own tastes to the product or service. Otherwise, who won't choose to buy the product or consume the service, due to it's price is higher than other general similar products or services if who has an imperfect understanding of whose own tastes to the product or service. So, it seems that the consumer's negative or positive emotion arise will be influenced by whose perfect or imperfect understanding of whose own tastes to the product or service factor.
