Today we're going to talk about attention. Attention is essential for processing the vast amount of information we face daily. Why do you think we need attention?
I think we need it to focus on what's important around us!
Exactly! Attention helps us filter out unnecessary stimuli. But did you know that there are different types of attention? Can anyone name one?
Selective attention?
That's right! Selective attention allows us to focus on specific stimuli while ignoring others. Letβs remember that as 'S' for 'Selective'!
What other types are there?
Great question! We also have divided attention, which is when we pay attention to multiple tasks at once.
And sustained attention, right?
Yes! Sustained attention is when we maintain focus over time. Remember this acronym: SSD, for Selective, Sustained, and Divided attention!
To summarize, attention helps us focus on what's relevant, filter out distractions, and can be categorized into three types: selective, divided, and sustained.

Letβs dive deeper into selective attention. Who can explain what influences our ability to focus selectively?
Maybe the size or brightness of the stimuli?
Exactly! External factors like size and intensity can grab our attention. What about internal factors?
I think our interests or needs might affect it!
Absolutely! Our motivations and cognitive states play major roles in how we attend to stimuli. A mnemonic to remember these factors is 'MICE': Motives, Intensity, Characteristics, and Experience.
How does that work in real life?
Think about when your favorite song plays in a noisy room. You might zone in on the music instead of the chatter. That's selective attention at work!
To summarize, selective attention allows us to focus on important stimuli, influenced by both external characteristics and our internal motivations.
Divided and Sustained Attention

Now, letβs discuss divided attention. Can anyone give me an example of divided attention?
Like when Iβm studying while listening to music?
Precisely! Divided attention allows multitasking, but it's usually effective when tasks are well-practiced. For example, experienced drivers talk while driving without losing focus. Remember: 'Practice makes perfect' for multitasking!
What about sustained attention? How does that differ?
Sustained attention requires maintaining focus over time on a single task. Think about air traffic controllersβthey need high vigilance to monitor continuously for safety. It's crucial for jobs that require long-term concentration!
This helps me understand why some people struggle with sustained attention.
Good observation! To recap, divided attention lets us juggle tasks effectively when practiced, while sustained attention is critical for tasks that need prolonged focus.
Introduction & Overview

Quick Overview
Standard
Attentional processes are vital in filtering the plethora of stimuli we encounter daily. The section outlines types of attentionβselective attention, which focuses on specific stimuli, sustained attention, which maintains focus for extended periods, and divided attention, which multitasks between activities. Various factors affecting these types of attention are discussed, including both internal and external influences.
Detailed
Detailed Summary of Attentional Processes
Attention is a crucial cognitive process that enables us to filter and select relevant information from numerous stimuli we encounter in our environment. This section presents three primary types of attention:
- Selective Attention: Involves concentrating on specific stimuli while ignoring others. Successful selective attention is influenced by external factors (like size and intensity of stimuli) and internal factors (such as individual motivations and cognitive processes).
- Divided Attention: Refers to our ability to focus on multiple tasks or stimuli simultaneously, typically occurring with well-practiced activities. This automaticity in processing allows individuals to multitask efficiently.
- Sustained Attention: Also known as vigilance, this type encompasses maintaining focus on a task or stimulus over an extended period, which is critical for roles that require continuous monitoring.
Factors affecting attention include characteristics of stimuli (external determinants) and personal motives or cognitive styles (internal determinants). Understanding attention is essential, as it plays a significant role in learning processes and our interaction with the environment.

In the previous section we have discussed some sensory modalities that help us in collecting information from the external world and also from our internal system. A large number of stimuli impinge upon our sense organs simultaneously, but we do not notice all of them at the same time. Only a selected few of them are noticed. For example, when you enter your classroom you encounter several things in it, such as doors, walls, windows, paintings on walls, tables, chairs, students, schoolbags, water bottles, and so on, but you selectively focus only on one or two of them at one time. The process through which certain stimuli are selected from a group of others is generally referred to as attention.
Detailed Explanation
Attention is the mental process of focusing on specific stimuli while ignoring others. When you enter a classroom, you're bombarded with many visual and auditory stimuliβdifferent objects, sounds, and movements. However, your brain prioritizes and selects certain stimuli, such as your teacher's voice or the board, to concentrate on while disregarding others, like background chatter or distant sounds. This process is crucial for effective learning and interaction in our environment.
Examples & Analogies
Imagine youβre at a bustling party, filled with conversation, music, and laughter. You want to have a meaningful chat with a close friend. To do this, you focus on their voice and the immediate surroundings while filtering out the noise and distractions. This is a daily example of how attention allows us to navigate our social environment.
Properties of Attention

At this point it may be noted that besides selection, attention also refers to several other properties like alertness, concentration, and search. Alertness refers to an individualβs readiness to deal with stimuli that appear before her/him. While participating in a race in your school, you might have seen the participants on the starting line in an alert state waiting for the whistle to blow in order to run. Concentration refers to focusing awareness on certain specific objects while excluding others for the moment. For example, in the classroom, a student concentrates on the teacherβs lecture and ignores all sorts of noises coming from different corners of the school. In search an observer looks for some specified subset of objects among a set of objects.
Detailed Explanation
Attention comprises various elements. Alertness is being ready to respond to stimuli, much like being on high alert before a race. Concentration is the ability to focus deeply on a task, such as listening to a teacher while ignoring distractions. Lastly, search involves actively looking for specific information among many options, like spotting your friends in a crowded place. These aspects show how multifaceted attention is and how it enables us to function effectively in complex environments.
Examples & Analogies
Think of a detective in a busy city trying to spot a suspect. They must be alert to any signs of the suspect while concentrating on their surroundings, ignoring other distractions like pedestrians or cars. The detective actively searches specific characteristics that identify the suspect, demonstrating the complex processes involved in attention.

Attention has been classified in a number of ways. A process-oriented view divides it into two types, namely selective and sustained. We will briefly discuss the main features of these types of attention. Sometimes we can also attend to two different things at the same time. When this happens, it is called divided attention.
Detailed Explanation
Attention can be categorized mainly as selective attention, which involves focusing on specific stimuli while ignoring others, and sustained attention, which is the ability to maintain attention on a single task or stimulus over a long period. Divided attention occurs when we manage to focus on multiple tasks at once, such as talking on the phone while cooking. Each type plays a vital role in our daily functioning, depending on the task at hand.
Examples & Analogies
Imagine a student taking notes while listening to a lecture. They employ selective attention by focusing on the teacher's voice (ignoring side conversations) and sustained attention by concentrating on the lecture for the entire class duration. If the student were to also message a friend during this time, they would be using divided attention, but may risk missing important information from the lecture.
Factors Affecting Selective Attention

Several factors influence selective attention. These generally relate to the characteristics of stimuli and the characteristics of individuals. They are generally classified as βexternalβ and βinternalβ factors. External factors are related to the features of stimuli. Other things held constant, the size, intensity, and motion of stimuli appear to be important determinants of attention. Large, bright, and moving stimuli easily catch our attention. Motivational factors relate to our biological or social needs. When we are hungry, we notice even a faint smell of food.
Detailed Explanation
Selective attention is shaped by both external and internal factors. External factors are physical characteristics such as size and brightness of stimuliβloud sounds or bright colors are more likely to attract our attention. Internal factors involve personal motivations; for instance, if you are hungry, you'll be more attuned to the smell of food than other smells in the environment. Understanding these factors can help explain why we focus on certain stimuli in various contexts.
Examples & Analogies
When walking through a market, your attention is drawn towards the vibrant colors of fruits and the delicious smells of food stalls (external factors). If you're on a diet, you might focus more on healthy options, demonstrating how personal choice and motivation can shape attention (internal factors).
Theories of Selective Attention

A number of theories have been developed to explain the process of selective attention. We will briefly discuss three of these theories. Filter theory was developed by Broadbent (1956). According to this theory, many stimuli simultaneously enter our receptors creating a kind of βbottleneckβ situation. Moving through the short-term memory system, they enter the selective filter, which allows only one stimulus to pass through for higher levels of processing.
Detailed Explanation
Several theories explain how we manage attention. Broadbent's Filter Theory suggests that as we process information, multiple stimuli create a bottleneck, and only one can pass through a 'filter' for deeper processing. This explains why we may hear a conversation in a noisy room but fail to register other sounds. Understanding these theories allows psychologists to gauge how attention works in various situations.
Examples & Analogies
Think of a busy coffee shop: many conversations happen simultaneously, but you can focus on your friend's voice thanks to the filter theory. Itβs as if your brain has a dial to tune out background noise and only listen to one conversation at a time.
Sustained Attention and its Importance

While selective attention is mainly concerned with the selection of stimuli, sustained attention is concerned with concentration. It refers to our ability to maintain attention on an object or event for longer durations. It is also known as 'vigilance'. Sometimes people have to concentrate on a particular task for many hours. Air traffic controllers and radar readers provide us with good examples of this phenomenon.
Detailed Explanation
Sustained attention, or vigilance, is the capacity to focus on a task for extended periods without losing concentration. This is particularly crucial in jobs requiring continuous monitoring, like air traffic control, where overlooking signals can lead to serious consequences. Strengthening sustained attention can enhance performance in various settings requiring prolonged focus.
Examples & Analogies
Imagine a lifeguard watching over a busy swimming pool. They must maintain high sustained attention, focusing on swimmers continuously to spot any signs of distress. This example illustrates how critical sustained attention is in ensuring safety in environments where acute awareness is necessary.
Span of Attention
Unlock Audio Book

Our attention has a limited capacity to receive stimuli. The number of objects one can attend to at a brief exposure (i.e. a fraction of a second) is called 'span of attention' or 'perceptual span.' On the basis of several experiments, Miller has reported that our span of attention varies within the limit of seven plus or minus two.
Detailed Explanation
The span of attention refers to how many items we can perceive at once, typically around five to nine. This 'magic number' indicates our cognitive limits in processing information at a given moment. For instance, when trying to remember a phone number, we often group the digits into segments to fit within this span, demonstrating how limited our immediate attention is.
Examples & Analogies
When you look at a grocery list, you may only remember a few items (like five to seven) at a time while shopping. If your list has more than seven items, you may have to look at it again to remember everything, highlighting the span of attention in action when managing information.
