The Influence Of Stimulus Color And Subject's Emotions On Temperature Perception

Temperature perception is an individual's cognition of the temperature of the object surface and surrounding environment,which has an important influence on human comfort,consumption decision-making,interpersonal communication and so on.In this study,two experiments were designed to explore temperature perception and its influencing factors.The effects of stimulus color,actual temperature and subject emotion on temperature perception,as well as the relationship between color and temperature concept were investigated.Experiment 1 investigated the effects of stimulus color and physical temperature on individual temperature perception under different emotional priming.It was a mixed experiment design of 5(stimulus colors: red,yellow,green,blue,transparent)× 3(physical temperature: 40?-45?,20?-25?,0?-5?)× 2(emotional activation: positive and negative).Among them,stimulus colors and physical temperature were the within participate variables,emotional priming was the between participate variable.The dependent variable was the temperature estimation of participates.The results showed that:(1)The main effect of emotion was obvious.The temperature estimate of the participants with positive emotion was higher than negative participates.(2)The main effect of physical temperature was obvious,and the participants' temperature estimated error value of the object between 0? and 5? was higher than that of the object between 40? and 45?.(3)The interaction between physical temperature and stimulus color was obvious.At 20?-25?,the temperature of red objects was lower than the objects of other colors,and at 40?-45?,the temperature of red objects was higher than the objects of other colors.(4)There was significant gender difference in the temperature estimate,and the temperature estimate of male participants was higher.(5)The interaction of physical temperature and gender was obvious.At 0?-5?and 20?-25?,the temperature of men was significantly higher than women.Experiment 2 explored whether there is an implicit connection between the stimulus color and the concept of temperature,providing evidence of implicit cognition for the relationship between temperature perception and stimulus color.An implicit association test was used to measure the connection between stimulus colors(red,yellow,blue,green,purple)and temperature concept(cold,warm).The results showed that:(1)Compared with compatible task(cold color-cold word,warm color-warm word)and incompatible task(cold color-warm words,warm color-cold word),the time required for participants to complete the task increased significantly,and there was a relationship between stimulus colors and temperature concept Implicit effect.(2)The interaction between emotion and gender was obvice.Under negative emotions,the color-temperature conceptual association was stronger in men.Under positive emotions,women's color-temperature concept is stronger.Conclusions:(1)Emotion and stimulus color both affect the explicit and implicit cognitive processes of temperature perception.(2)There are gender differences in individual temperature perception.At 0?-5? and 20?-25?,men have higher estimates of the temperature of objects.(3)There is an implicit connection between the stimulus color and the concepts of temperature,which is embodied in the following aspects: cold colors matching with cold words,warm colors matching with warm words.There are significant differences in the intensity of the implicit association between different genders in different emotional states.
