Is our attention span truly rivaling that of a goldfish in this age or is there still hope for the highly evolved Homo Sapiens? Neuroscientists argue that the increasing influence of technology in our everyday lives has persistent detrimental impacts on the human brain’s cognitive functions in particular on attention.
Are the Technophobes right?
How many of you have your parents take your phones before exams? Our youth takes pride in multi-tasking, browsing through the YouTube homepage while sending out that very important email. Multitasking itself is a cognitive function that requires acute use of divided attention but is digital multitasking enhancing or dividing our attention? Neuroscientists Junco and Cotton conducted a study on the effect of digital multitasking on students’ learning. Their results show that the more students engaged in multiple activities in digital environments, the worse their academic performance was.
A questionnaire was circulated to identify heavy media multitaskers from light media multitaskers to test whether media multitasking may improve short-term memory, task-switching, and ignoring distractions. The results were quite contrary to the hypothesis with heavier media multitaskers performed worse on the series of cognitive tasks.
Capitalism? Capitalism!
Prolonged exposure to technology is changing our information absorption ability. We are now becoming “cognitive off-loaders”, i.e. we prefer to memorize where the information is stored instead of the information themselves. Our voluntary engagement with task materials is constantly interrupted by elements specifically designed to capture involuntary attentional processes like popups and ad banners. Advertisements and other forms of “persuasive technology” also join this list.
Newsfeeds and videos that are less than 10 minutes have rewired our cognitive pathways. Our brains are learning to scan information and pick out what appears “significant” whilst disregarding the rest. Rather than deep-reading articles, we focus on snippets and form our mental key takeaways. This has led researchers to fear that our brains will remain no longer capable of sustained concentration such as that the one required to read novels, and the key skills needed for critical thinking and long-term learning are being replaced by a shallow engagement due to our split attention spans!
