Bottom-up mechanisms are thought to operate on raw sensory input, rapidly and involuntarily shifting attention to salient visual features of potential importance – the spot of red against a field of green that could be a piece of fruit, the sudden movement that could be a predator.
What is bottom up processing in psychology?
Bottom-up processing occurs as our sensory receptors receive new sensory information and does not require the use of prior knowledge or experiences. Bottom-up processing is data-driven and emphasize the importance of the stimulus itself, the raw data of the direct experience. Bottom-up processing would function in a series ...
What is the difference between bottom-up and top-down processing?
Bottom-up processing is the process of ‘sensation’ and top-down is the process of ‘perception’. Sensation is the input of sensory information from our external environment that is received by our sensory receptors.
How do I start the bottom-up process?
To begin the bottom-up process, observe simple details in your environment. While you may have background knowledge about a particular place or situation, focus on what you can sense at the moment, such as what you can see, hear and feel. While gathering sensory details, you may notice: 2. Transfer sensations
What is the bottom up theory of perception?
The theory of bottom-up processing was introduced by psychologist E. J. Gibson, who took a direct approach to the understanding of perception. Rather than being dependent upon learning and context, Gibson felt that perception was a “what you see is what you get” process.
What is meant by bottom-up process?
Bottom-up processing can be defined as sensory analysis that begins at the entry-level—with what our senses can detect. This form of processing begins with sensory data and goes up to the brain's integration of this sensory information.
What is an example of a bottom-up process?
Bottom up processing is when sensory receptors pick up signals for the brain to integrate and process. An example of this is stubbing your toe on a chair, the pain receptors detect pain and send this information to the brain where it is processed.
What is meant by a top-down process in attention?
Top-down attention refers to the voluntary allocation of attention to certain features, objects, or regions in space. For instance, a subject can decide to attend to a small region of space in the upper-left corner or to all red items.
What is top-down and bottom-up processing in perception?
So, bottom-up processing is data-driven, and your perception of what it is that you're looking at directs your cognitive awareness of the object. So, in contrast, top-down processing basically uses your background knowledge, so uses your background knowledge to influence perception.
Why is it called bottom-up processing?
It's called “bottom-up” because it begins with the external stimulus — such as a tree or the smell of cookies — and then that sensory information moves to the brain for analysis.
What is another name for bottom-up processing?
What is another name for bottom-up processing? Data-based processing.
Why is bottom-up approach better than top-down?
The top-down approach relies on higher authority figures to determine larger goals that will filter down to the tasks of lower level employees. In comparison, the bottom-up style of communication features a decision-making process that gives the entire staff a voice in company goals.
What is bottom-up and top-down processing quizlet?
Bottom-up. Analysis that begins with the sense receptors and works up to the brains integration of sensory information. Top-down. Information processing guided by higher level mental processes, as we construct perceptions drawing on our experience. You just studied 7 terms!
What is the best example of a top-down process?
One classic example of top-down processing in action is a phenomenon known as the Stroop effect. In this task, people are shown a list of words printed in different colors. They're then asked to name the ink color, rather than the word itself.
Which is best described as bottom up processing?
What is Bottom Up Processing? Bottom-up processing is the idea that we begin to perceive items with sensation, as opposed to our conceptual ideas. This process is also known as “data-driven processing,” because it is just that: driven by the data that we collect with our senses.
Is reading an example of bottom up processing?
Bottom-up processing happens when someone tries to understand language by looking at individual meanings or grammatical characteristics of the most basic units of the text, (e.g. sounds for a listening or words for a reading), and moves from these to trying to understand the whole text.
What is bottom up processing in psychology quizlet?
Define bottom-up processing. Involves processing information by starting with the individual elements of a visual stimulus and gradually building up a final representation and interpretation (Grivas, et al, 2006). Focusus on gestalt, depth and constancy principles.
Which is best described as bottom-up processing?
Bottom-up processing is the process of 'sensation', whereby the input of sensory information from the external environment is received by our sensory receptors. Perception is how our brains choose, organize, and interpret these sensations.

How do people process perceptual information from the world around them?
How exactly do people process perceptual information from the world around them? There are two basic approaches to understanding how this sensation and perception takes place. One of these is known as bottom-up processing and the other is known as top-down processing .
How do we make sense of the world?
In order to make sense of the world, we must take in energy from the environment and convert it to neural signals, a process known as sensation . It is in the next step of the process, known as perception, that our brains interpret these sensory signals. Verywell / Emily Roberts.
Why do we see human faces in ambiguous shapes?
However, because our brains are predisposed to perceive faces and because of top-down processes, we are likely to begin to see a human face in these ambiguous shapes.
What is the ecological theory of perception?
Because Gibson’s theory suggests that processing can be understood solely in terms of environmental stimuli, it is something referred to as the ecological theory of perception.
What happens when you see a letter on your screen?
For example, if you see an image of an individual letter on your screen, your eyes transmit the information to your brain, and your brain puts all of this information together.
Where do electrical impulses travel?
Transduction transforms these signals into electrical impulses that can then be transmitted. Electrical impulses travel along visual pathways to the brain , where they enter the visual cortex and are processed to form our visual experience.
What happens when you stub your pinky toe?
Upon stubbing your pinky toe, the pain receptors in your toe would have immediately recognized the sensation of pain and sent these very pain signals to your brain where they are processed. This would be considered bottom-up processing as your brain is receiving signals of pain sent by your pinky toe’s sensory receptors.
What is the input of sensory information from our external environment that is received by our sensory receptors?
Sensation is the input of sensory information from our external environment that is received by our sensory receptors. Bottom-up processing is the process of ‘sensation’, whereby the input of sensory information from the external environment is received by our sensory receptors. Perception is how our brains choose, organize, ...
What is bottom up processing?
The bottom-up process involves information traveling 'up' from the stimuli, via the senses, to the brain which then interprets it, relatively passively. Bottom-up processing is also known as data-driven processing, because the processing of information begins with environmental stimuli, and perceptions are built from sensory input.
What is the driving force of perception in bottom up processing?
Whereas in bottom-up processing, no learning is required, and perceptions are solely based on new stimuli from one’s current external environment, meaning that the driving force of perception in bottom-up processing is the stimulus that is currently being experienced within one’s external environment (Gibson, 1972).
What does Gibson's theory of perception mean?
Meaning that Gibson’s theory argues that perception functions as a straight line, we experience new stimuli through our sensations and then directly analyze their meaning.
What did Gibson believe about the environment?
Unlike Gregory’s theory (1970), Gibson believed that the environment holds all of the necessary tools to create accurate perceptions of incoming stimuli.
What is the driving force of top down perception?
In top-down processing we know that previous knowledge, experience, and expectations are essential in creating perceptions about new stimuli, so the driving force in top-down perception is one’s previous knowledge, experience, and expectations (Gregory, 1974).
What is the brain's capacity to process sensory stimuli?
The brain is limited in its capacity to process all sensory stimuli present in the physical world at any point in time and relies instead on the cognitive process of attention to focus neural resources according to the contingencies of the moment.
How does attention affect the mean neuronal firing rate?
Attention affects the mean neuronal firing rate as well as its variability and correlation across neurons. Although distinct processes mediate the guidance of attention based on bottom-up and top-down factors, a common neural apparatus, the frontoparietal network, is essential in both types of attentional processes.
What Is Bottom-Up Processing?
- Bottom-up processing is a psychological strategy people use to perceive the world. People who use bottom-up processing assess their surroundings through their senses before applying any sort of analysis. For example, if you use bottom-up processing while sitting down to read an article on your computer, you might notice the blue light of the screen...
How Does The Bottom-Up Process Work?
- The bottom-up process involves both voluntary and involuntary actions. Be mindful of your senses to help you be alert to your surroundings to begin the bottom-up process. After you absorb sensory information, your body reacts to it, and your mind processes it. Using a bottom-up understanding can help you take action or understand a situation. Here are steps to follow for a…
Bottom-Up Processing vs. Top-Down Processing
- Bottom-up processing and top-down processing are the two fundamental psychological theories for how people process the world around them. People may also combine them to form conclusions based on both what they observe and what they know. While both are useful, it's important to know the differences between the theories, which include: Related: What Are Cognit…
Advantages of The Bottom-Up Process
- Depending on the situation, you may choose to use top-down or bottom-up processing. For example, in a new environment where you have little background knowledge reference, using bottom-up processing may help you evaluate what's happening and make appropriate choices. Bottom-up processing at work can also benefit you in the following ways: 1. Mindset shift: Usin…

Because Gibson’s theory suggests th…
Real-Life Applications
- You can compare how bottom-up processing works to how top-down processing works by considering examples of how each process works. Imagine that you see a somewhat obscure shape. If you saw the shape on its own, using bottom-up processing, you might immediately perceive it as a capital letter B. Now if someone were to place that image next to other context c…
A Word from Verywell
- Bottom-up processing can be extremely useful for understanding certain elements of how perception occurs. However, research has also shown that other factors including expectation and motivation(elements of top-down processing) can have an impact on how we perceive things around us.
