Technology and the Developing Self
Every generation of adults has worried that the new thing is rotting young minds — novels, television, comics, now phones. Psychology’s job is to ask whether the worry is supported. This page gives you the strongest argument for technology, the strongest argument against, and the reason the question is so hard to settle.
📚 What you need to know
Prensky (2009) argues digital technology is making children smarter, not lazier, because digital tools extend what a mind can do.
He introduces digital wisdom: using technology to make better decisions than you could unaided.
His key claim is a balanced one — technology alone will not replace intuition, good judgement, problem solving or a moral compass.
Supporting arguments: games demand sustained attention, switching between tools trains flexibility, and hyperconnectedness gives children a global community.
Opposing arguments: gaming addiction, over-reliance on shortcuts, unchecked information, and the google effect leading to digital amnesia.
The biggest research problem is comparison: there is no fair tool for measuring cognition across generations, and no agreement on what “intelligence” is.
Fifteen-mark answers here need both sides plus a judgement — not a list of opinions about screens.
Prensky’s argument, in plain words
Prensky starts from a gap he thinks is now closer to a gulf: children born after the internet handle technology as a first language, while everyone else learned it later. His claim is that this changes what children can do cognitively. They reach a vast amount of information instantly, and they can run analyses that used to take a specialist a week.
But he is careful, and students often miss this. He does not say technology replaces thinking. He says the opposite: intuition, judgement, problem solving and a moral compass still have to come from the person. What technology does is give a person with those qualities far more reach. He calls the combination digital wisdom.
A useful way to check any claim about technology: is the tool doing the thinking, or extending it?
Watch the wording in the exam. “Technology makes children smarter” is a headline. “Technology gives children who already think well a much longer reach” is the actual argument. The second version is far harder to knock down.
The case for: what growing up digital might build
Sustained attention. Playing a competitive online game demands minutes of focused, updated attention — more than passively watching television ever asked for.
Task switching. Moving between several forms of technology at once may train flexibility and the ability to hold more in working memory.
Information handling. Children routinely sort, filter and compare more sources in a day than earlier generations met in a month.
Hyperconnectedness. A child can feel part of a global community, which supports identity development and exposure to other cultures.
Complex analysis. Tools that were once specialist — maps, statistics, translation, design — sit on a phone.
The case against: what it might cost
Gaming addiction and dependency, especially where games are designed to be hard to stop.
Overuse of shortcuts. If an answer is always one search away, the effort that builds deep understanding may never happen.
Unchecked information. Websites carry false or unverified claims, and parents and teachers cannot see what a child is absorbing as fact.
The google effect. Relying on search engines can lead to digital amnesia — being so dependent on external storage that memory for the information itself weakens.
Notice the scale is not level. The honest answer is that the evidence currently allows a lean, not a verdict.
Why nobody can settle this argument
This is the part that lifts an answer from good to excellent. The debate is not unresolved because psychologists are lazy. It is unresolved because the study you would need is close to impossible.
🧩 Three reasons the question stays open
No fair comparison tool. To compare thinking across generations you need a test that is equally fair to both, but every test is written inside a culture. A test that rewards fast information sorting flatters today’s teenagers; one that rewards memorising long passages flatters their grandparents.
No agreement on “intelligence”. If you define it as knowledge held in your own head, technology looks harmful. If you define it as solving problems with the tools available, technology looks helpful. The definition decides the answer before any data is collected.
You cannot randomise childhood. Nobody can assign children to grow up with or without technology, so almost all evidence is correlational and full of confounding variables such as income and parenting.
A sharp evaluation point: Prensky writes as an advocate making an argument, not as a researcher reporting an experiment. His claims are plausible and useful, but treating them as evidence is a mistake. Say this and back it up by asking what data would be needed to test him.
Worked examples
WORKED EXAMPLE
To what extent can we conclude that digital technology boosts children’s cognitive development? [15 marks] — two paragraphs from a longer answer
Paragraph arguing for
There is a reasonable case that digital technology supports cognitive development. Children now use tools that place real demands on attention and working memory: a fast online game requires continuous updating of goals, and moving between several applications trains cognitive flexibility. Prensky argues that these tools give children access to information and analysis that previous generations could not reach, and that combining that reach with human judgement produces what he calls digital wisdom. Dismissing children’s technology use as mindless would be the lazy reading; the demands are often higher than those made by older forms of entertainment.
Paragraph arguing against
The costs are equally visible. Reliance on search engines has been linked to the google effect, where people remember where information is stored rather than the information itself, a pattern sometimes called digital amnesia. Easy shortcuts may prevent the effortful processing that builds durable understanding, and unfiltered online content makes it hard for adults to know what children are accepting as fact. Gaming can also tip into dependency, which harms development in ways that have nothing to do with cognition.
Judgement
The honest conclusion is that the evidence supports a shift rather than a boost. Technology appears to strengthen some skills, such as switching and information handling, while weakening others, such as unaided recall. Because the debate depends on how intelligence is defined, and because childhood cannot be randomly assigned, no strong causal conclusion is currently available in either direction.
WORKED EXAMPLE
Explain one difficulty researchers face when comparing cognition across generations. [3 marks]
Point
There is no comparison tool that is equally fair to both generations.
Explain
Any cognitive test reflects the skills valued when it was written. A test built around rapid searching and filtering suits people raised with technology, while one built around sustained reading and recall suits those who were not.
Link
This means a difference in scores may reveal what the test measures rather than a genuine difference in cognitive ability, so conclusions about which generation thinks better lack validity.
💡 Exam tip
State Prensky’s claim accurately. He argues technology extends thinking, not that it replaces it. Getting that right earns credit.
Use “digital wisdom” as a term and define it in your own words — using the tools well, not simply owning them.
Pair every benefit with a cost. Attention gains against digital amnesia; global community against unchecked content.
Bring in the definition problem. Pointing out that the answer depends on how intelligence is defined is a genuinely high-level move.
Say why the research is correlational. You cannot randomly assign a childhood, so causal claims are unsafe.
Anchor abstract points in an example — one game, one search habit, one classroom situation.
⚠ Common mix-up
Turning the essay into a rant about screen time. Opinions without evidence do not score.
Treating Prensky as a study. It is an argument, and that is itself a valid criticism to make.
Saying multitasking is proven to improve cognition. The evidence points both ways; say so.
Confusing the google effect with forgetting everything. It is a shift in what gets remembered — location instead of content.
Ignoring confounding variables. Wealth, schooling and parenting travel with technology access and can explain differences on their own.
Forgetting a judgement. “To what extent” always needs a verdict at the end, even a cautious one.
