The better we understand attention, the better we’re able to support learning. So what do we need to know about attention? I’ve been digging around the research, and here’s what I think is valuable.
1. Attention can be thought of as a limited resource.
Attention is a limited cognitive resource that can be consciously allocated to various tasks. Attention has important constraints that affect memory and learning. First, people have a limited ability to pay attention; fatigue will set in after a sustained effort. Also, because we can only process a limited amount of information simultaneously, we must select where to put our focus.
2. Selective attention equals focused attention.
Selective attention is what we usually think of as focusing our attention on something. This state of mind occurs when a person selects specific inputs to process while avoiding distractions in the environment.
Brain-imagery studies have shown that some irrelevant stimuli may be processed during periods of focused attention, but to a lesser extent. For example, if you are reading in a coffee shop with just the right amount of low-level noise, you may be bombarded with sensory information. Yet you are able to use selective attention to focus on reading, even though you may still hear the buzz of a conversation nearby.
3. Two different types of sources can capture attention.
Psychologists speak of bottom-up and top-down influences on attention. Attention captured from bottom-up events happens without effort. It’s automatic. Think of how the piercing cry of a baby, the annoying GIF animation on a webpage (movement), or the sweet aroma of freshly baked bread captures your attention. Our senses detect these bottom-up stimuli without conscious effort. Perhaps much of the sensory information that captures attention is or was helpful to survival.
On the other hand, top-down events control attention when an individual makes a conscious shift to focus on something other than attention-grabbing external stimuli. Top-down influences come from an internal source and involve a person’s intentions and goals.
4. Top-down selection is relevant to working memory.
Attention that is directed by top-down goals is most likely based on information held in working memory. This is what makes the information meaningful. We select the stimuli that is relevant to what we are trying to accomplish. For example, if you want to find a certain pair of shoes, you hold the features of the object in working memory.
5. Susceptibility to distractions is lowest when a task engages your full attention.
Distractions refer to task-irrelevant information. A person uses selective attention to ignore distractions. It is easier to get distracted when a task involves a low perceptual load, meaning that the task is not all-encompassing. Conversely, it is easier to remain on task when the task has a high perceptual load, meaning it is entirely engaging. Perhaps another way to think of this is that it is easy to get distracted during repetitive or boring tasks.
6. Multitasking divides attention.
You already know this. When you respond to two or more channels of information simultaneously, you divide your attention. Divided attention appears to use more mental resources because the tasks may be conflicting, such as listening to one thing and watching another, and the brain must coordinate two or more tasks at the same time. Research described in Cognitive Psychology: A Student’s Handbook shows that divided attention reduces performance on a task.
7. The ability to divide attention is influenced by the similarity of the tasks.
When tasks are similar to one another, it is more difficult to divide attention between them. For example, trying to listen to two streams of audio information—such as someone speaking to you while you listen to a podcast—makes it difficult to attend to. On the other hand, if one information stream is auditory and the other is presented visually, it is easier to attend to the second stream. According to the book Cognitive Psychology, other factors that affect well how a person can divide attention include:
- similarity of response required
- similarity in the types of cognitive processes used
- difficulty of the tasks.
And in case you are wondering, most research shows that talking to someone while driving—whether on the phone or in person—reduces the ability to react as quickly as when you are not talking. Unlike a mobile conversation, however, a passenger will often stop talking when it is important for the driver to pay more attention.
8. Split-attention in instructional materials increases cognitive load.
When multiple sources of information are not well integrated, it causes the split attention effect, according to Richard Mayer’s book, Multimedia Learning. An example is a narrated explanation that occurs before an animation. Or instructions that need to be continuously referenced and are physically separated from the problem task. This requires learners to hold one set of information in working memory while processing another stream of information. The solution is to integrate multiple sources of information into one coherent piece.
9. An abrupt change can capture attention.
You can capture attention through any change in stimulus, which is why novelty works so well. Experienced learning designers will often capture attention with something unexpected, innovative, or surprising. In e-learning, you may need to do this repeatedly.
10. Sustained attention requires something meaningful, challenging, or special.
Sustained attention refers to focusing on an activity for an extended period of time. Many appropriate strategies for sustaining attention involve the design of learning experiences that are relevant to the world of the learner or novel, as mentioned in number 9. In e-learning it could be a moving story of a protagonist who overcomes the odds, a well-executed animation for explaining a complex concept, or a challenging problem to solve. Think in terms of:
- arousing curiosity
- interjecting emotions
- critical inquiry
- collaboration and knowledge sharing
- fantastical worlds.
Attention, memory, and learning have a complex relationship. By delving into how attention works, we can design and support learning in more appropriate and innovative ways.
