Item Open Access Costumers’ emotional and behavioral responses under different accent lighting conditions in a real retail store(2018-11) Gümüşay, BüşraThe aim of the study is to understand the influence of lighting color temperature on costumers’ emotional and behavioral responses in a real retail store. In the experiment three different color temperatures were used on LED track spot lights that illuminates a living room furniture set. This study was conducted with 90 participants who were customers and accepted participant acceptance protocol. Thirty customers participated for each lighting condition (2700K as Warm White (WW), 5000K as Artificial Daylight (DL), 6500K as Cool White (CW)). Observation method was used to conduct behavioral analysis. Behavior mapping was used to analyze understanding of the custumers’ behavioral responses. Mehrabian and Rusell’s M-R model was used to analyze emotional responses. PAD (Pleasure, Arousal, Dominance) model was preferred to conduct a questionnaire in order to measure customers’ emotional responses. Results showed that color temperature influenced on costumers’ emotional and behavioral responses. Under warm white (WW) color temperature, people feel more pleasure than cool white color temperature. Under WW color temperature people spent more time in front of the illuminated furniture set. Contrast color temperatures (WW and CW) increased the levels of pleasure and arousal scales of emotional responses.Item Open Access The effects of color temperature on performance and mood of users : a color task implementation model(2017-07) Kürkçü, EsraThis study aimed to explore the effects of color temperatures on color task performance, and also to propose a color task implementation model to be used in future research. In the study, three attributes of color were the focus in the color differentiation task. The study was conducted with 100 participants as with-in subjects design, in a full-scale office set-up under two different color temperature; warm white light (2700K and cold white light (4000K. The speed and accuracy of the color task were examined as an indication of task performance. The mood change of participants was assessed by Watson’s Positive and Negative Affect Schedule (PANAS mood measurement, self-satisfaction was assessed by Office Lighting Survey (OLS and perceived performance was assessed by questionnaire. The results showed that the total time spent for the color tasks performances have no significant. difference between 2700K and 4000K. It also showed that total accuracy of color task performances is statistically better under 4000K, compared to 2700K. Whereas color temperatures did not affect value differentiation task performance significantly, hue and chroma differentiation tasks performance were significantly better under 4000K color temperature. In terms of the effects of color temperature on mood, it is found that 4000K color temperature affected participants mood in a positive way. Also, self-satisfaction and perceived performances of participants are significantly better under 4000K color temperature.Item Open Access The effects of correlated color temperature on wayfinding : a study in a virtual airport environment(2013) Kumoğlu, ÖzgeThe aim of the study is to understand the effects of correlated color temperature on wayfinding performance in airports and to compare different color temperatures in order to understand their effects on wayfinding performance. The experiment was conducted with three different sample groups in three different lighting settings that are 3000 K, 6500 K and 12000 K. The participants were total ninety graduate students from twenty-one different departments of twenty-six different universities. The study was conducted in a single phase. The volunteered participants experienced the desktop VE one by one. The participants were seated at the computer and were tested by the researcher. They were asked to direct the researcher from the starting point to the final destination which was stated as gate numbered 109. It was found that correlated color temperature has no significant effect on wayfinding performance in terms of the time spent, the total number of error, the total number of decision points and the route choice during finding the route. However, the correlated color temperature has a significant effect on experiencing hesitations. It was found that the total number of hesitations decrease while the correlated color temperature increases from 3000 K to 12000 K.
