Reflection: On digital technology’s affect on attention span, sparked by the video ‘The Death of Critical Thinking: How Stupidity Took Over‘ by Aperture
Technology plays a major role in how we think, learn, and focus. With the creation of social platforms like TikTok and Instagram, the effect on our attention spans and critical thinking has been drastically reduced. In 2024, a study found that a person’s average attention span on a digital device is 47 seconds, a large drop from 75 seconds in 2012. I think this is a result of how platforms like these; that deliver fast, engaging content, designed to capture a user’s attention instantly, are changing the way we process information. Â
Technology is fundamentally changing the way we think, not just short-term content, but in general. Our reliance on technology trains our minds to expect immediate stimulation and as a result, tasks like reading, writing, and studying, things that require sustained attention, have begun to feel more difficult to complete. This doesn’t just apply to the younger generations, but âfor everyone, across all ages, depending on digital products as a crutch does affect your brain physically.â
One of the videos examples references studies of brain imaging that focused on people who relied on GPS to navigate. Studies have found that people who are heavy users of GPS have smaller hippocampus sizes than people who do not. Contrastingly, a study that focused on the brains of taxi drivers who had to memorize complex city roads have a larger hippocampus. This happens because the hippocampus is the region of the brain responsible for spatial memory. When a person uses GPS, it essentially turns their mind on autopilot, preventing the hippocampus from strengthening. Â
This has led to a correlation between stress and attention span. When you switch your attention so rapidly, you’re not processing information, reflecting, or thinking deeply. When your mind doesnât deliberate the information it receives, over time it becomes more difficult to understand, comprehend, and retain it. When this happens to a person, their levels of stress increase, as completing tasks is more difficult and taxing on the mind. Â
I think this is why the learning of digital literacy is so important. Digital literacy is not just the understanding of techology and digital products, but the understanding of how they affect us. The need for digital literacy is more prevalent than ever, with the creation of short-term digital content and reducing attention span, a personâs ability to critically think continues to decline. We need a way to navigate the digital world, so that we can maintain our complex thoughts, so that we can function with as little stress as possible, so that we can think for ourselves and not have to rely on digital technology.
Reflecting on my own experience, I have to constantly stop myself from scrolling and swiping. Itâs gotten better over the years, Iâve become more mindful of what I consume, reminding myself to put my effort and attention into my work and necessary tasks. I remember at times that just having my phone in my proximity made it nearly impossible to complete anything of value. But by understanding the effects of technology, I was able to regain my concentration.
