Question

In the attentional context, “signal” refers to what we want to attend to while “noise” refers to everything else. Clarify what would result in the best relationship between those two for optimal attention, and carefully describe the consequences of frontal lobe injury on an optimal SnR.

this is a 12 mark question, answer accordingly.

Answer 1

For the purpose of attention, signal refers to the message which needs to be implemented by the receiver after excluding all the attention cues from the environment and the sender. For the purpose of optimal attention, noise from the communication system should be eliminated as much as possible; these noises can be auditory or visual in nature. An injury to the frontal lobe of the brain can lead to difficulty in achieving optimal Sir levels which will basically increase the threshold that is required by an individual to perceive the sensitivity towards Signal to noise ratio which means that the signal needs to be stronger as compared to the noise for the individual who has experienced injury in their frontal lobe of the brain which is usually 20db and can increase up to 50db. This means that the individual has difficulty in perceiving and dedicating their attention to signal to noise ratio less than 50 decibels.

Hope this helps; please like for efforts.
