Key Studies of Technology and Cognition

students, think about the last time you used your phone to check a fact, find a route, or remember a password 📱. Technology can help cognition, but it can also change how we pay attention, remember, and make decisions. In IB Psychology SL, the cognitive approach studies how mental processes such as attention, memory, and thinking shape behaviour. This lesson focuses on key studies that show how technology affects cognition and why these findings matter in real life.

What you will learn

By the end of this lesson, students, you should be able to:

• explain the main ideas and terms connected to technology and cognition,
• describe key studies and what they found,
• use IB Psychology-style reasoning to interpret evidence,
• connect the studies to the broader cognitive approach,
• and apply these ideas to real situations such as schoolwork, driving, and social media use.

The core idea is simple: technology can change what we notice, what we remember, and how we think. Some studies show that digital tools can improve performance when they reduce mental effort. Other studies show that constant access to information may weaken memory or divide attention. 🧠

Technology as cognitive support and cognitive load

A useful way to understand this topic is to separate two effects of technology. First, technology can act like an external memory aid. For example, calendars, search engines, and navigation apps store information for us, so we do not need to hold everything in our minds. This can free up mental resources for more complex tasks.

Second, technology can increase cognitive load. Cognitive load means the amount of mental effort being used in working memory. If a device sends repeated notifications, or if a person keeps switching between apps, attention becomes divided. Since working memory is limited, extra distractions can reduce performance.

This is important in the cognitive approach because psychologists study how people process information rather than just how they behave. In other words, technology may not only change behaviour directly; it may also change the mental processes behind that behaviour.

Study 1: The Google effect and transactive memory

One major idea in this area is the Google effect, also called digital amnesia. This is the tendency to forget information that can be easily found online. The key point is not that technology destroys memory, but that people may remember where to find information instead of remembering the information itself.

This idea is linked to transactive memory, which means memory shared across people or tools. In everyday life, a group of friends may divide up what each person remembers. With technology, the “group” can include a phone, a search engine, or a cloud account. students, if you know you can quickly search for the capital of a country, you may not try as hard to store it in long-term memory.

A well-known study by Sparrow, Liu, and Wegner found that people were less likely to remember information when they believed it would be available later on a computer. However, they remembered where to find the information. This supports the idea that access to technology changes what gets encoded in memory. The study is useful because it shows a real-world example of cognition adapting to modern life.

In IB terms, the study supports the cognitive approach because it investigates mental processing, especially memory encoding and retrieval. It also shows that cognition is not fixed; it can be shaped by the environment and by expectations about technology.

Study 2: Technology, attention, and multitasking

Another key area is the effect of technology on attention. Attention is the ability to focus on certain information while ignoring other information. Many digital devices encourage multitasking, such as texting while studying or switching between tabs during homework.

Research has shown that multitasking often reduces performance because the brain is not truly doing two demanding tasks at once. Instead, it is rapidly switching attention. Each switch takes time and uses mental energy. This can lead to slower work, more mistakes, and weaker memory for what was learned.

A useful example comes from studies on media multitasking. Heavy media multitaskers sometimes perform worse on tasks that require filtering out distractions. This suggests that frequent exposure to many streams of information may affect selective attention. Selective attention is the ability to focus on one source of information while ignoring others.

For everyday life, this matters a lot. If students studies with notifications turned on, each alert may break concentration and interrupt the flow of working memory. Even short interruptions can hurt learning because new information has not had enough time to be processed deeply.

From a cognitive perspective, this is connected to the idea that working memory has limited capacity. When technology pulls attention in several directions, the brain has less capacity for understanding, storing, and using information.

Study 3: GPS, navigation, and spatial cognition

Technology also affects spatial cognition, which is how people understand and remember locations, directions, and relationships in space. Navigation apps like GPS make travel easier, but they can change how much people rely on their own mental maps.

Studies on GPS use suggest that when people rely heavily on turn-by-turn instructions, they may pay less attention to environmental cues such as street layouts, landmarks, and directions. As a result, they may learn routes less deeply than people who navigate without assistance.

This does not mean GPS is bad. In fact, it is very helpful in unfamiliar places or emergencies. But it can reduce active processing. When someone reads a map, plans a route, or mentally turns a map around, they are engaging in more effortful spatial reasoning. That effort can strengthen memory for the environment.

This connects to the broader cognitive approach because it shows that cognition is active. People do not just receive information; they organize, interpret, and store it. Technology can either support or replace these processes.

Study 4: Social media, emotion, and cognition

Technology does not only affect memory and attention. It also influences the way people think about themselves and others. Social media platforms are especially important because they combine information, emotion, and decision-making.

One issue studied by psychologists is how online feedback affects cognition. Likes, shares, and comments can shape self-perception and decision-making. If students posts something and receives positive feedback, that may influence how students interprets social situations. Negative or missing feedback may also affect mood and thinking.

This area is connected to cognitive biases and schema. A schema is a mental framework or organized pattern of thought. People may use schemas to interpret what online reactions mean. For example, someone might think, “No one liked my post, so people do not care about me.” That conclusion may not be accurate, but it shows how cognition can be influenced by incomplete information.

Research also suggests that social media can encourage rapid judgment rather than careful thinking. Because posts are brief and fast-moving, users may form impressions quickly. This can increase the chance of errors in decision-making. In IB Psychology, this links with the reliability of cognition: our thoughts can be influenced by context, emotion, and available cues.

How to apply IB Psychology reasoning

When answering exam questions on this topic, students, you should do more than list facts. You should explain the psychological mechanism and connect it to evidence. A strong answer often follows this pattern:

1. define the key concept,
2. describe the study or example,
3. explain what the results show about cognition,
4. connect it to the cognitive approach,
5. and add a brief real-life application.

For example, if asked how technology affects memory, you could explain that online access encourages transactive memory. You might mention that people remember where information is stored rather than the information itself. Then you could link this to the idea that memory is selective and depends on what seems useful to store.

If asked about evaluation, you can consider strengths and limits. A strength of this research is that it has high real-world relevance because people use technology every day. A limitation is that some findings may change as technology changes. What people do with phones or apps today may be different from what people did a few years ago. This means psychologists must be careful not to overgeneralize from one device or one time period.

Why these studies matter in the cognitive approach

These key studies show that cognition is practical and adaptive. Humans do not have unlimited memory or attention, so they develop strategies to manage information. Technology can extend mental ability by storing data, giving reminders, and helping with navigation. At the same time, it can create distractions and reduce deep processing.

This lesson also shows an important IB idea: behaviour is linked to mental processes, and mental processes are influenced by context. Technology is part of that context. It shapes what we notice, how we remember, and how we decide.

In real life, this helps explain why some students learn better when they silence notifications, why drivers use GPS but still may not know a route, and why people often remember the location of information online instead of the content itself. 📚

Conclusion

The key studies of technology and cognition show that digital tools can both support and change mental processes. Research on the Google effect, multitasking, navigation, and social media demonstrates that memory, attention, and decision-making are influenced by how we interact with technology. For IB Psychology SL, students, the most important takeaway is that cognition is not isolated from the modern world. It develops and operates within it.
