As sped-up content becomes increasingly common in digital media consumption, understanding its cognitive and perceptual implications is essential. This study investigated whether video playback speed affects time and speed perception. Participants watched videos at two speeds (0.5x and 1.5x), followed by tasks assessing temporal reproduction, verbal estimation, reaction time, and subjective speed perception. Results showed that playback speed influences temporal perception and attentional processes: slowed playback was associated with subjective time dilation and better performance in the attentional task, while sped-up playback led to temporal underestimation and increased perceived speed. Both conditions may impair cognitive functioning, with accelerated playback potentially posing greater risks for tasks requiring precise timing and sustained attention.
