This paper intensively examines the effects of gender and seasons on impression factors of pictures using word pairs. Previous studies have presented four impression factors for females and males: Evaluation, Potency, Sharpness, and Freshness. However, this paper finds that, for males, the factor of Sharpness could more accurately be described as Tenseness. Additionally, the factor of Freshness could be more appropriately described as Dryness for both males and females, although they have different impressions. This paper also shows that several impression factors are affected by the season rather than the temperature.
