Question 1

Attention research between 1860 and 1909

Answer 1

Between 1860 and 1909, psychologists began to explore the concept of attention more systematically. They investigated how people focus on specific things while ignoring others, and how attention affects perception, memory, and decision-making. This period laid the foundation for understanding attention as a crucial mental process, leading to further research and development in psychology.

Question 2

Sternberg’s additive factors method

Answer 2

Sternberg’s additive factors method is a psychological research technique used to understand how people process information and make decisions. It involves presenting participants with tasks that require mental processing, such as remembering lists of numbers or solving mathematical problems. By manipulating different factors, such as the complexity of the task or the time available to respond, researchers can observe how these factors interact to influence performance. The method helps researchers identify the separate stages of cognitive processing and how they are affected by different variables, ultimately shedding light on the underlying mechanisms of human cognition.

Question 3

The relation between arousal, task performance and attention

Answer 3

Certainly! The relation between arousal, task performance, and attention is like a three-way dance. Arousal is how alert and energized you feel, like being wide awake or sleepy. When you’re more aroused, your attention tends to sharpen, focusing better on tasks. This heightened attention can boost task performance, helping you do things more effectively. However, if arousal gets too high or too low, it can mess up your focus and performance, like trying to dance when you’re too jittery or too tired. So, it’s about finding the right balance of arousal to keep attention sharp and performance at its best.

Question 4

Event-related potentials

Answer 4

Sure! Event-related potentials (ERPs) are electrical patterns in the brain that occur in response to specific events or stimuli, like sounds or visual cues. They’re measured using electrodes placed on the scalp. ERPs help researchers understand how the brain processes information and how different cognitive processes unfold over time, providing insights into perception, attention, memory, and other mental activities. Essentially, they give us a glimpse into the brain’s real-time reactions to different stimuli, helping us understand how the brain works.

Question 5

Signal-detection theorie

Answer 5

Certainly! Signal detection theory is a framework used to understand how people make decisions when they’re trying to detect the presence of a signal (like a faint sound in a noisy environment) amidst background noise. It involves distinguishing between two states: the presence of a signal (signal present) and the absence of a signal (signal absent). The theory considers factors like sensitivity (how well someone can detect a signal) and decision criteria (the standard someone uses to determine whether a signal is present or absent). Overall, it helps explain how people navigate uncertain situations to make judgments about the presence or absence of a signal.

Question 6

Early selection models of attention

Answer 6

Sure! Early selection models of attention suggest that when we’re exposed to a lot of information, our brains filter out irrelevant stimuli very early in the process, even before we consciously perceive them. This means that only the most important or relevant information gets processed deeply, while the rest gets discarded or processed only superficially. In simpler terms, it’s like our brain quickly deciding what’s important to focus on and what can be ignored, even before we’re fully aware of it.

Question 7

Late selection models of attention

Answer 7

Late selection models of attention suggest that all incoming information is processed to some extent, but only relevant information is consciously attended to and further processed for higher-level cognitive functions. In these models, selection of relevant information occurs after initial processing, closer to the level of conscious awareness. This means that irrelevant information may still be processed to some degree, but only relevant information is fully attended to and processed deeply.

Question 8

Exogenous attention shifts

Answer 8

Exogenous attention shifts are automatic movements of attention driven by external stimuli in our environment. These shifts occur involuntarily, drawing our attention to sudden or unexpected events, such as a loud noise or a bright light. Unlike endogenous attention, which is controlled by our goals and intentions, exogenous attention shifts happen without our conscious effort, helping us quickly detect and respond to important stimuli in our surroundings.

Question 9

Endogenous attention shifts

Answer 9

Endogenous attention shifts refer to the process where your brain deliberately chooses to focus on something specific, usually based on your goals, intentions, or expectations. It’s like when you decide to concentrate on reading a book despite distractions around you because you’re interested in the content. These attention shifts are internally driven and help you direct your cognitive resources towards what you consider important or relevant.

Question 10

Space-based versus object-based attention

Answer 10

Sure! “Space-based attention” refers to how our attention is directed to specific locations or areas in our environment. It’s like focusing on a particular spot in a room. On the other hand, “object-based attention” involves directing our attention to specific objects or items within that space, regardless of their location. It’s like noticing a particular object amidst other things in the room. So, space-based attention focuses on where things are, while object-based attention focuses on what things are.

Question 11

Visual search

Answer 11

Sure! Visual search is like using your eyes to search for something instead of typing words. You take a picture of an object or scene, and a special technology analyzes the image to find similar items or provide relevant information. It’s helpful for finding products online, identifying objects, or exploring places visually without needing to describe them in words.

Question 12

Shadowing

Answer 12

Certainly! “Shadowing” in the context of attention refers to the ability to focus on one particular stimulus while ignoring others. It’s like when you’re listening to someone speak in a crowded room, and despite the noise, you’re able to concentrate solely on what that person is saying. This skill helps us filter out distractions and maintain focus on the task or information that’s most important at the moment.

Question 13

Broadbent about dichotic listening

Answer 13

Certainly! Broadbent’s research on dichotic listening involves studying how people process different auditory inputs when they’re presented simultaneously to each ear. He found that people tend to focus on one message while ignoring the other, showing a limited capacity for processing auditory information. This research helps us understand how our attention works, showing that we can’t fully process multiple inputs at the same time and must selectively attend to one while filtering out others.

Question 14

Attentional set (auditory information)

Answer 14

Sure! “Attentional set (auditory information)” refers to how our mind focuses on specific sounds or auditory stimuli while ignoring others. It’s like tuning into a particular radio station while disregarding the rest. This process helps us concentrate on what’s important or relevant in our auditory environment, like listening to a conversation in a noisy room.

Question 15

Reactive inhibition

Answer 15

Certainly! Attentional set, also known as reactive inhibition, refers to the ability of the brain to focus on specific information while ignoring distractions. It involves consciously directing attention to relevant stimuli while inhibiting responses to irrelevant or conflicting stimuli. Essentially, it’s like tuning into what’s important while tuning out what’s not, allowing us to concentrate on tasks effectively. This cognitive process is crucial for tasks requiring sustained attention and selective focus.

Question 16

Flanker-compatibiliy effects

Answer 16

Certainly! In psychology, Flanker compatibility effects refer to how distractions or irrelevant information can affect our ability to focus on a specific task. Imagine trying to concentrate on a central target (like a word or an image) while other surrounding stimuli (the “flankers”) either help or hinder your ability to focus. If the flankers are compatible (similar) to the target, they might make it easier to focus, but if they’re incompatible (different), they can make it harder by causing interference. This effect helps researchers understand how attention works and how we filter out distractions to focus better.

Question 17

Inhibition of return

Answer 17

Sure! “Inhibition of return” is a phenomenon in psychology where after you look at something, your attention tends to avoid going back to that same spot for a while. It’s like your brain temporarily tells you, “You already checked there, let’s look somewhere else.” This helps in efficiently scanning our environment by prioritizing new or potentially important information over things we’ve already seen.

Question 18

Visual marking

Answer 18

Visual marking is a concept in psychology that refers to the way our brains use visual cues to prioritize and focus attention on specific objects or areas in our environment. It’s like putting a mental highlighter on something important, making it stand out amidst other stimuli. This marking helps us quickly locate and process important information while filtering out less relevant details. It’s a fundamental mechanism that helps us navigate and make sense of the visual world around us.

Question 19

Negative priming

Answer 19

Sure! Negative priming is a psychological phenomenon where when you’re asked to ignore or disregard a specific stimulus, it actually slows down your response to it later on. For example, if you’re told to ignore the color red, but then asked to respond to it, your reaction might be slower compared to if you hadn’t been told to ignore it at all. This suggests that the act of trying to ignore something can actually make it harder to react to it quickly when you need to.

Question 20

Psychological refractory period (PRP)

Answer 20

Sure! The Psychological Refractory Period (PRP) refers to a phenomenon where our brains struggle to process two tasks simultaneously if they are presented very closely together in time. It’s like when you’re asked to do two things at once, like typing while someone is talking to you; your brain might need a moment to switch its focus from one task to the other. This delay in processing the second task is known as the PRP, and it shows how our attention can be limited when tasks are presented rapidly, one after the other.

Question 21

Task switching

Answer 21

Task switching refers to the ability to shift your focus and attention from one task to another. Imagine you’re working on homework and suddenly your phone buzzes with a notification. When you stop doing homework to check your phone, you’re switching tasks. It involves disengaging from one activity, like homework, and engaging with another, like checking your phone. However, every time you switch tasks, there’s a mental cost as your brain needs to readjust, which can reduce overall efficiency compared to focusing on one task at a time.

Question 22

Types of memory

Answer 22

Sure! In the context of attention, there are different types of memory that help us process and retain information.

Sensory Memory: This is like a quick snapshot of what we perceive through our senses. It’s very brief, lasting only a few seconds, and helps us decide what to pay attention to.

Short-term Memory: Also known as working memory, this holds information temporarily while we’re actively thinking about it. It has limited capacity and duration, typically around 20-30 seconds, and helps us focus on tasks at hand.

Long-term Memory: This is where information is stored for longer periods, from minutes to a lifetime. It’s like our mental library, where we keep important knowledge and experiences. We retrieve information from here when needed, influenced by attention and rehearsal.

These types of memory work together to help us process and retain information, with attention playing a crucial role in determining what gets stored and how effectively we can recall it later.

Question 23

Baddeley’s working memory model

Answer 23

Sure! Baddeley’s working memory model is like a mental workspace where we temporarily store and manipulate information to help us complete tasks. It consists of three main components: the phonological loop for auditory information, the visuospatial sketchpad for visual information, and the central executive which controls attention and coordinates the other two components. It’s like a mental whiteboard where we jot down and manipulate information to help us focus on tasks at hand.

Question 24

Bottlenecks in information processing in PRP and attentional blink

Answer 24

Sure! Imagine your brain is like a busy highway where information travels. Bottlenecks in information processing in the context of PRP (Psychological Refractory Period) and attentional blink are like traffic jams on that highway.

In PRP, there’s a delay in responding to a second task when it comes too quickly after the first one because your brain is still processing the first task, creating a bottleneck in the flow of information. Similarly, in attentional blink, your brain temporarily “blinks” or misses processing certain information when it’s presented too closely together with other information, creating another bottleneck. These bottlenecks show limitations in how quickly and efficiently our brains can process incoming information.

Question 25

Wickens’ multiple-resource model of multi-tasking

Answer 25

Certainly! Wickens’ multiple-resource model of multitasking suggests that when people try to do more than one task at a time, they use different mental resources. These mental resources can be things like visual attention, auditory attention, or motor skills. According to Wickens, if two tasks require different mental resources, people can usually perform them simultaneously without much interference. However, if two tasks require the same mental resource, they will interfere with each other, making it harder to perform both tasks well at the same time. So, in essence, it’s like juggling different tasks: it’s easier if you’re using different types of objects (or mental resources), but it’s harder if you’re trying to juggle the same type of object (or mental resource).

Question 26

Norman & Shallice’s model of action control

Answer 26

Norman & Shallice’s model of action control is a psychological framework that helps us understand how we carry out complex tasks. It suggests that our actions are controlled by a combination of automatic and controlled processes. Automatic processes are like habits or routines that we do without much thought, while controlled processes involve conscious attention and decision-making. According to this model, when something unexpected happens or when a task requires special attention, our controlled processes kick in to adjust our actions accordingly. It’s like having a built-in system that helps us manage our attention and actions effectively.

Question 27

Effects of aging on attention

Answer 27

Certainly! As people age, their ability to pay attention to things may change. This could mean they might have more difficulty focusing on tasks, staying alert, or filtering out distractions. Factors like changes in brain structure and function, as well as health conditions, can contribute to these effects. Overall, aging can impact attention by making it harder to concentrate and stay focused compared to when someone is younger.

Question 28

Intelligence and attention

Answer 28

Intelligence and attention are closely related concepts. Intelligence involves the ability to understand, learn, and solve problems effectively. Attention is the mental focus or concentration on specific stimuli or tasks. In simpler terms, intelligence helps us process information, while attention determines what we focus on within that information. Think of attention as the spotlight that directs our intelligence to particular things, guiding our understanding and problem-solving abilities.

Question 29

The mismatch negativity

Answer 29

Certainly! “Mismatch negativity” (MMN) is a brain response that occurs when we notice something unexpected or different in our environment. It’s like your brain’s way of saying, “Wait, that doesn’t seem right!” This response happens automatically, even when you’re not actively paying attention to it. MMN is useful because it helps us detect changes in our surroundings, even if we’re focusing on something else.

Question 30

Cortex and selective attention

Answer 30

Sure! The cortex is the outer layer of the brain responsible for processing information from our senses and controlling our thoughts and actions. Selective attention is our ability to focus on certain things while ignoring others. In the brain, the cortex plays a key role in selective attention by directing our focus to specific stimuli while filtering out distractions. So, when we concentrate on something, our cortex helps us tune out irrelevant information and focus on what’s important.

Question 31

Circadian fluctuations in cognitive function

Answer 31

Certainly! “Circadian fluctuations in cognitive function” refers to the natural changes that happen in our mental abilities throughout the day, following our body’s internal clock or circadian rhythm. For example, most people tend to be most alert and focused during the daytime, while attention and cognitive function might dip during the late night or early morning hours. These fluctuations impact how well we can pay attention to tasks or process information at different times of the day.

Question 32

Functions of the prefrontal cortex

Answer 32

Sure! The prefrontal cortex is like the commander-in-chief of your brain, especially when it comes to attention. It helps you focus on tasks by filtering out distractions, making plans, and organizing your thoughts. Think of it as the brain’s supervisor, keeping you on track and helping you pay attention to what’s important.

Question 33

CODELAB Experiments

Answer 33

CODELAB experiments refer to a series of tests or trials conducted to explore and understand how attention works in the context of computer programming or coding. These experiments typically involve observing how programmers allocate their focus, manage distractions, and handle complex tasks while writing code. By analyzing these experiments, researchers aim to uncover insights that can improve coding practices, enhance productivity, and optimize learning strategies for programmers.

Question 34

EEG (ERP and oscillations)

Answer 34

Certainly! EEG stands for electroencephalography, a method used to measure electrical activity in the brain. ERP (Event-Related Potentials) refers to brain responses that are directly linked to a specific event or stimulus, such as when someone pays attention to something. Oscillations are rhythmic patterns of brain activity that can also be linked to attention. By analyzing EEG data, researchers can study how these brain responses and patterns change when someone focuses their attention on something, helping us understand the neural mechanisms involved
