The Relationship Between Perception and Attention
PDF | This article discusses several key issues concerning the study of attention and its relation to visual perception, with an emphasis on. Enhance your understanding of attention and perception in psychology by This lesson will use examples to teach you about this relationship and walk you. Attention is a central process and perception is not possible without attentional That means attention precedes perception. .. the size –distance relationship.
Perceptual and memory representation can be and often largely are pre-conscious. Cognitive control does not have content. In this case with CSA at hand it is easier to understand why attention in one case facilitates consciousness of contents and in some other case does not or even dampens it.
Attention as the principal mechanism of selection out of alternative informational options can either facilitate the working or use of the CSA or inhibit or abstain from use of it.
The likely possibilities of relationship between attention mechanisms and the CSA mechanism are as follows: Which one of the above relationships is valid or whether both can be implemented requires special research in future. At present there are several candidate mechanisms for acting as the special mechanistic intermediate between pre-conscious information-representing activity and conscious-level information-representing means.

In the family of thalamocortical interaction theories assuming a special role for the so-called non-specific-thalamic units for upgrading the pre-conscious cortical contents there are several varieties e. In some of the models post-synaptic EPSPs of the content-carrying cortical neurons are the targets for non-specific-thalamic modulation e.
The second-order binding is executed via the oscillations of the non-specific CSA system. In this version, a representation is essentially a dynamic representation. Attentional network can be though either to aid pre-conscious binding, binding for consciousness, or exhausting or desynchronizing the oscillatory resources in case of adverse effects on consciousness.
In the reentrant theory it is assumed that for the specific contents represented by primary sensory cortices to become consciously represented, they need to be accessed by the reentrant signals from the higher-order cortical nodes sent back to the already activated earlier units Lamme, ; van Gaal and Lamme, Bottom-up plus top-down cycles of mutual activation are sufficient for consciousness of its contents.
In this theory the mechanism is not neuroanatomically distinct albeit interacting with differently placed other modules as is the case with thalamic theories. It is functionally defined, implemented by the neural units that are neuroanatomically the same. Although Lamme and van Gaal explain attentional effects both independent and associated with consciousness, there are some questionable aspects to this theory.
First of all, it would be computationally and adaptively suspect to leave both the functions of representation and modulation to the units of the same neural system. One and the same structural system should have difficulty in transforming from content-representing system to a control system and vice versa, unless some mystique would be brought in.
Let me end with a few concluding remarks.Lecture 13- Sensation & Perception
In order to better understand the nature of attention and consciousness and their relation i some conceptual distinctions either absent or only implicitly involved in theorizing so far are necessary. This applies to the distinction between: Also, ii it may be advisable to abandon both the attention-as-consciousness, view, and the view that consciousness emerges by default from the work of traditional mechanisms of perception, memory, and attention.
Instead, let us find a deserved place for the special mechanism of consciousness in addition to the perceptual, attentional, memory, cognitive control, and other standard mechanisms long acknowledged. Methodologically, iii in addition to the mostly correlational studies NCC more mechanistic and causal-effects related research is needed.
Let us accept that there is a special thalamocortical interactive? This concept is functionally apart from the concepts of perception and attention.
Therefore, we may have better chances to solve the attention versus consciousness puzzle.
Indeed, both perception and attention can be independent of the explicit conscious experience. Conflict of Interest Statement The author declares that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. There is no such thing as attention.

There are different types of attention according to scientists, namely; focused attention, sustained attention, selective attention, alternating attention and divided attention Gear, Perception allows a person to interpret information from our senses based on existing information and expectations.
As such, perception enables individuals to create meaning from the sensory nerves. There are different types of perception including perceptual constancy which allows the mind to recognize an image from varying angles, light intensity and from different distance Gear, For instance, white color appears the same under different light intensity and objects remain the same whether at close or long distance.

Generally, perception helps us to create mental image which leads to an action. In most cases, when one sees fire or a lion the mind decide what to do. So smell, touch, sight and sound determine how we perceive things.
In the same way, when we see an animal such as a cat in our environment the sensory nerves are able to construct the image which is then created in the mind, this is perception.
The same case happens when we hear certain sounds we are familiar with which we are able to interpret and form an image based on that. This creates the relationship between attention and perception.
