42 flat-spectrum radio-loud narrow-line Seyfert 1 galaxies(including 8 gamma-ray loud sources)were selected.Using photometric data from the Wide-field Infrared Survey Explore(WISE),we studied the infrared variability characteristics of both gamma-ray-loud and non-gamma-ray-loud sources,along with the contribution of star formation processes to infrared variability.The results show that:(1)all sources exhibit intra-day variability(IDV);(2)compared to the non-gamma-ray-loud sources,the gamma-ray-loud sources have on average higher IDV duty cycle and long-term variability amplitude;(3)the impact of star formation process on infrared variability could be neglected.
