The constructivist theory of perception postulates that we make assumptions about what we see not only based on the sensations we receive, but also on our expectations and past knowledge. Learning and past experience are crucial in shaping how we perceive the world.
Gibson proposed an alternative theory: perception is innate and not learned. Humans have evolved to make accurate judgments based solely on the sensory information we receive. Gibson noted that as we move, we receive detailed information about depth and distance directly, without inferences about the necessary visual cues.

Theories of Perception in Psychology
There are two main approaches to understanding perception in psychology. One theory, the direct theory of perception proposed by Gibson (1966), postulates that what we perceive is a direct representation of the world around us. Furthermore, the information provided by the environment is sufficient to lead directly to perception.
Gregory's constructivist theory of perception holds that sensation provides ambiguous and incomplete information about the environment. Therefore, the interpretation is necessary to create a mental picture of our world.
In the constructivist view, we do not perceive the world directly. What we perceive is our interpretation that our past experiences, beliefs, expectations and emotionsthis can influence.
Sensationrefers to the detection of sensory data by our senses. For example, our auditory system detects sound waves and converts them into nerve impulses.According to constructivists, perception is the conscious experience of sensation (eg, the experience of hearing), which involves interpretation and inference..
Gibson's theory of direct perception
Gibson's theory (1966) argued thatperceptionit is adirectprocess. direct, meaningsensationsthey themselves areenoughto create acomplete representation of the worldaround us.Gibson challenged the constructivist view; proposed that there is no need for interpretation or inference assensory data is enough.
Here is an overview of the main points of Gibson's theory of perception.
- Perception is a direct bottom-up process. Perception does not require the use of past knowledge or the interpretation of sensory data.
- Sensory data is rich, complex, and sufficient to make accurate environmental judgments.
- Perception is an innate process that is the result of evolution.
Sensory data such as visual information is complex and can provide us with information such as depth, movement or distance.
Inference it means drawing conclusions or conjectures about what we perceive based on the sensory data we have. The constructivist approach proposes that perception is based on inference.
The influence of nature on perception
Direct perception was proposed as innate and not learned. It probably evolved as a product of evolution. Direct perception allows animals to respond quickly and reliably to environmental threats and therefore benefit their survival. Animals that developed the ability to quickly process information from the environment were therefore more likely to survive.
bottom-up perception theory
Gibson's theory proposes that perception is a bottom-up process. Upstream processing isdata orientedand entirely based on sensory information.
Sensory information (light) from the environment meets the retina; it is transformed into electrical impulses and processed in the visual cortex as a conscious experience of vision.
This process is straightforward, information only travels in one direction, and no previous experience or interpretation is needed to make accurate judgments about the environment.
Fig. 2 - Upstream processing.
On the contrary, thetop-down theoryof perception (constructivist approach) argues that our past experiences and expectations strongly influence perception. Prior knowledge is used to make assumptions and interpret the sensations we experience.
Fig. 3 - Top-down processing.
Example of Gibson's theory of direct perception
We'll examine real-life examples of Gibson's theory, including accessibility and motion parallax.
accessibility
Gibson is considered one of the founders ofecological psychology. Ecological psychology proposes that perception should be studied in a natural environment rather than a laboratory and that perception and action are inherently connected. Our environment directly guides our behavior, providing us with opportunities to act. Gibson referred to these opportunities asbenefits.
The possibilities of the environment are what it offers the animal, what it furnishes or provides, whether for good or ill. — Gibson (1979)
The idea of possibilities is that we receive information about how we might act when looking at objects. According to Gibson, we can directly perceive the possibilities; we don't need any prior knowledge to decide how to act.
If we see a chair, we also see the benefits of a chair. For example, we can sit on a chair, stand or move it.
motion parallax
Motion parallax is a visual monocular depth cue. Think about how objects in your field of view move when you move. When we move, nearby objects appear to move faster relative to us, while distant objects appear to move more slowly.
Motion parallax is a way to get information directly about the distance of objects around us based on the sensory input we receive.
You may experience motion parallax when looking out the window of a moving car or train. You may notice that buildings or trees in the distance are moving significantly slower than trees and objects closer to the road.
If you look at objects that are very far away (like the moon), you can feel that they are not moving.
The fact that perception guides our actions can be used to make people slow down when driving. By gradually placing painted lines on the roads closer and closer together, drivers may think they are accelerating, which may cause them to slow down.
These changes in road marking promote safe driving, which is an example of the practical application of Gibson's theory.
D ratingdirect theory of perception
Gibson's (1966) theory addresses some of the limitations of the constructivist approach, which undermined the direct role of sensory data. However, critics also point out some problems with this approach.
Strengths of the direct theory of perception
First, let's examine the strengths of the direct theory of perception.
- The theory rightly points out that much of perception is innate and does not require past experience. For example, babies intuitively show a fear of rights when approaching a cliff, even if they have never fallen off a cliff before.
- Sensory data can provide accurate information about motion and depth, as evidenced by motion parallax.
- Perception also happens relatively quickly; we can respond to the environment almost instantaneously, which best explains the direct theory of perception. The constructivist view of perception requires additional interpretation of the information, which may take longer than direct perception.
Limitations of the direct theory of perception
Now let's examine the limitations of the direct theory of perception.
- A limitation of Gibson's theory is that it does not explainvisual illusions, which shows that sometimes the sensory information is insufficient to accurately represent what we perceive.
Some stimuli (for example, distorted images or sounds) do not make sense to us. Still, after we receive another stimulus, we can suddenly understand them (for example, the hidden optical illusion of the Dalmatian dog).
You may remember the famous blue versus white dress illusion that went viral in 2015. Some people perceived the same image of a dress as blue and black, while others perceived it as white and gold, while the image remained the same. Gibson's theory cannot explain this.
Gibson argued that illusions are artificial and often taken out of context, so our perception of them is inaccurate. Our perception has evolved to make sense of rich sensory stimuli embedded in even richer contexts. Natural illusions limit this argument. Natural illusions occur in the natural world, despite the rich context in which they are embedded.
An example of a natural illusion is the waterfall illusion. After observing the water falling from a waterfall for some time, if we look at the rocks near the waterfall, we can see that they are moving upwards, in the opposite direction to the movement of the water we were observing.
It's also not clear how the benefits work. Some have argued that most possibilities result from learning rather than innate knowledge.
It's hard to ignore the instances where we don't directly perceive everything in our environment. Especially in busy environments, we can focus on more important stimuli while selectively ignoring others.
Inattentional blindness is a phenomenon that occurs when we do not perceive something unexpected in our visual field because ourattentionfocused elsewhere. In one experiment, participants were instructed to watch a video of people passing a basketball to each other and focus on counting how many times the ball was passed between people wearing white but not black T-shirts.
During this task, half of the participants did not notice a person dressed in a gorilla costume who appeared and smacked his chest in the middle of the screen (Simons & Chabris, 1999).
The cocktail effect refers to our ability to filter out specific information from background noise. When we're in a noisy environment like a party, we can still focus on a conversation we're having and tune out the noise around us. Likewise, we can detect words of personal importance from the loud background noise that occurs when we hear our name in a conversation we weren't having.attentiona.
Gibson's theory of direct perception: key points
- According to Gibson, perception is adirectprocess that does not require prior knowledge or inference. The sensory data themselves are rich and sufficient to allow us to make accurate judgments about our environment.
- The direct theory of perception holds that perception is innate and not learned. Perception likely evolved to allow animals to respond quickly to their environment.
- Gibson's theory proposes that perception is a bottom-up process. Upstream processing isdata orientedand entirely based on sensory information. Information only travels in one direction.
- Benefits are the opportunities to act offered by the environment. They can be perceived directly.
- Motion parallax is a monocular depth cue experienced during motion. Motion parallax tells us about the distance of objects relative to us.
- Gibson's theory correctly points out that we can obtain a lot of information and make accurate judgments based on sensory data, especially in natural environments. Furthermore, perception is generally instantaneous, which supports the direct theory of perception.
- Gibson's theory does not explainvisual illusionsor selective perception. It's also not clear how accurately the features work and whether or not they require prior knowledge.
FAQs
What is Gibson's direct perception theory? ›
Gibson (1972) argued that perception is a bottom-up process, which means that sensory information is analyzed in one direction: from simple analysis of raw sensory data to ever increasing complexity of analysis through the visual system.
What is Gibson's theory of direct realism? ›In brief, Gibson's theory is that visual perception is not a process of inferring from or organizing visual sensations produced by light falling on the retina, but rather a process in which the total visual system extracts (picks up) information about the environment from the light at the eye(s) of the organism as it ...
What is an example of direct perception theory? ›For example, when one ape observes another one reaching into a tree, grabbing something and then putting it into its mouth, this should be directly perceived as feeding without need for reflection.
What is Gibson's differentiation theory of perceptual development? ›Gibson, proposes that the senses are all unified at birth and that perceptual development is characterised as a gradual process of differentiating increasingly finer levels of sensory stimulation.
What are the strengths of Gibson's theory? ›An important strength of Gibson's theory is that it: Explains how we fill in visual details according to what we expect. Is a good explanation of visual illusions. Explains how we have to learn depth perception.
What is direct realist theory of perception? ›Direct Realism
Perceptual realism is the common sense view that tables, chairs and cups of coffee exist independently of perceivers. Direct realists also claim that it is with such objects that we directly engage. The objects of perception include such familiar items as paper clips, suns and olive oil tins.
Gibson argued that instinct and biology play a vital part in perception and therefore, when referring to the nature vs. nurture debate, this theory lies firmly on the nature side, as Gibson implies that the ability to perceive things and process information is innate, i.e. that a person is born with such an ability.
What is direct realism in simple terms? ›In philosophy of perception and philosophy of mind, naïve realism (also known as direct realism, perceptual realism, or common sense realism) is the idea that the senses provide us with direct awareness of objects as they really are.
Who proposed the theory of direct perception? ›A theory of (mainly visual) perception, developed by the US psychologist James Jerome Gibson (1904–79) over a period of more than three decades, according to which the flux of light (called the ambient optic array) reaching the visual receptors (1) of a perceiving organism is richly structured; movements of the ...
What is the theory of perception in psychology? ›Perception in psychology can be defined as the sensory experience of the world, which includes how an individual recognizes and interpreter sensory information. This also includes how one responds to those stimuli. Perception includes these senses: vision, touch, sound, smell, taste, and proprioception.
What are the 3 theories of perception? ›

What did Gibson and Walk believe about the development of depth perception? ›Gibson and Walk found that a variety of species could discriminate depth by the time they could walk, and animals such as chicks and goats that walk at birth could immediately perceive depth.
What is Gregory's constructivist theory of perception? ›Gregory's Constructivist Theory
This view states that perception depends on making inferences based on past experiences. In other words, the information hitting the senses is limited, so some degree of problem solving is necessary in order to work out what the world is like.
The two contrasting theoretical approaches to visual perception, the constructivist and the ecological, are briefly presented and illustrated through their analyses of space and size perception.
What is Gibson's bottom up theory? ›Gibson's bottom up theory suggests that perception involves innate mechanisms forged by evolution and that no learning is required. This suggests that perception is necessary for survival – without perception we would live in a very dangerous environment.
What are the strengths of Gregory's theory of perception? ›Strengths. Explains distortions well, such as Muller Lyer illusion and Ponzo illusion. In the Ponzo illusion, the depth cue linear perspective says that it is perceived to be more distant, it is scaled up, so seems bigger than the bottom bar. Explains ambiguous figures well, such as Necker's cube and Leeper's Lady.
What is Gregory's theory of perception evaluation? ›Richard Gregory's constructivist theory of perception argues that past knowledge and experience is the most important factor when making sense of the world around us. Gregory proposed that perception worked by making reasonable guesses about what we are seeing based on what it is most likely to be.
What is direct and indirect realism perception? ›For supporters of direct realism, the contents of perception are the very things of the real world; while for the defenders of indirect realism, the contents of perception are things at least in part dependent on the subject who experiences them.
What is direct versus indirect perception? ›Direct realists have it that we perceive physical objects directly. Indirect realists, such as sense datum theorists, have it that we perceive mental proxies for physical objects directly. A third question centers on the nature of properties perceived directly.
What is a realist perspective in psychology? ›The realist acknowledges the cognitive/constructivist nature of critical enquiry: it is fallible, thus, provisional, and cannot claim absolute truth. Realism acknowledges that we work in a reality consisting of relations; thus, some of us enquire about these relations and others focus on the terms.
How does Gibson propose to connect perception and action in his theory? ›
He suggested that people are truly seeing what they think they see; he claimed there is a natural and innate link between perception and action. Gibson's theory is called the ecological approach to perception because it focuses on the individual organism and its environment.
How does Gibson's direct theory of perception compare with Gregory's constructivist theory of perception? ›Gregory's theory is a top-down theory whereas Gibson's theory is bottom-up. Gregory's theory suggests that perception is influenced by nurture / learning and past experiences, whereas Gibson's theory suggests that perception is influenced by nature and inborn biological factors rather than learning.
What is direct perception? ›the theory that the information required for perception is external to the observer; that is, one can directly perceive an object based on the properties of the distal stimulus alone, unaided by inference, memories, the construction of representations, or the influence of other cognitive processes.
What is an example of direct realism? ›Remember, direct realism says that we perceive the external world directly as it is. But if this is true, how is it that reality (i.e. the external world) can be different to our perception of it? For example, when a pencil is placed in a glass of water, it can look crooked. But it isn't really crooked.
Why is direct realism wrong? ›Direct Realism is false. We do not directly perceive physical objects. The proponent of the argument then usually proceeds to claim that some tertium quid (e.g., a sense-datum, idea or the like) is the immediate object of perception. The first three premises are unobjectionable.
What are the two main theories of perception? ›There are two types of theories to perception, there is the self-perception theory, and the cognitive dissonance theory. There are many theories about different subjects in perception.
What are four types of perception in psychology? ›Types of Perception
This includes visual perception, scent perception, touch perception, sound perception, and taste perception.
Stimulation (understanding stimuli exist) Organization (comparing existing knowledge with the stimuli) Interpretation (making meaning of the stimuli) Memory (Storage of one's experience about the stimuli)
What are the 4 types of perception? ›The question for cognitive psychologists is how we manage to accomplish these feats so rapidly and (usually) without error. The vast topic of perception can be subdivided into visual perception, auditory perception, olfactory perception, haptic (touch) perception, and gustatory (taste) percep- tion.
What is an example of perception in psychology? ›For example, upon walking into a kitchen and smelling the scent of baking cinnamon rolls, the sensation is the scent receptors detecting the odor of cinnamon, but the perception may be “Mmm, this smells like the bread Grandma used to bake when the family gathered for holidays.”
What is the simple definition of perception in psychology? ›
Perception (from Latin perceptio 'gathering, receiving') is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment.
What is Locke's theory of perception? ›First, in his main work in epistemology, An Essay Concerning Human Understanding, Locke seems to adopt a representative theory of perception. According to Locke, the only things we perceive (at least immediately) are ideas.
