Effect of perceived control on human thermal comfort in heated environments

To study the effects of perceived control on human thermal sensation and thermal comfort in heated environments,a psychological experiment was conducted.In total,24 subjects participated in an experiment.The experiment consisted of two cases in which the indoor temperature was set at 18℃ with different cold radiation temperatures.The experiment lasted for 120 min and was divided into three phases,adaptation,without perceived control and perceived control.In the second phase,the subjects were told in advance that the indoor temperature could not be adjusted.In the third phase,subjects were told that they could adjust the indoor temperature to meet their own thermal expectations,but the indoor temperature could not actually be changed.The results showed that the effect of perceived control on thermal sensation was related to the thermal expectation.For people with strong expectations for a neutral environment,perceived control improved their thermal sensation by satisfying their thermal expectations.For people with low thermal expectations,perceived control reduced their thermal tolerance to the environment,eventually leading to thermal discomfort.These new findings provide more supports for the importance of psychological effects and a reference for the personal control of heating temperatures.

Identifying the key purchase factors for organic food among Chinese consumers

The current study primarily aims to identify the critical purchase factors that affect Chinese consumer purchase intention and purchase decision with regard to organic food consumption,in accordance with a modified theory of planned behavior and the alphabet theory.Specifically,this study builds a conceptual research framework by which to delve into the relationships between purchase factors and purchase intention,and elucidate the mediating roles of purchase factors in the relationships between purchase intention and purchase decision.Moreover,by leveraging a modified theory of planned behavior and the alphabet theory,the current study also determines the critical roles of subjective norms and reveals the information and knowledge that impact consumer attitude toward the purchase of organic food.The current study leverages the purposive sampling method and captures 310 records within Beijing,China.The results indicate that purchase attitude correlates positively with subjective norms and knowledge,while purchase intention correlates positively with purchase attitude,perceived behavior control,and food therapy culture.Furthermore,purchase intention can significantly mediate relationships between each of purchase attitude,perceived behavior control,food therapy culture,and purchase decision.Finally,we discuss the theoretical and practical significance of the framework,and propose subsequent research directions regarding organic food purchase behavior.
