The person’s failure to respond to the second stimulus while continuing to respond to the first stimulus is because of:

Correct option is B

The correct answer is Psychological Refractory Period (PRP).
1. The Psychological Refractory Period (PRP) refers to the phenomenon where an individual fails to respond to a second stimulus when it is presented while the individual is still processing the first stimulus. This occurs because the brain's cognitive resources are occupied by the processing of the first stimulus. Once the first stimulus has been processed, the second stimulus is then addressed. This results in the failure to immediately respond to the second stimulus.
2. The PRP effect highlights the limitations of dual-task processing and the bottleneck that occurs in the brain when it is unable to process multiple stimuli simultaneously.

Types of Refractory Period

1.1. The term "refractory period" is used in both psychology and neurobiology to describe a period of time following a stimulus during which a system (either the brain or the nervous system) is less responsive to subsequent stimuli. In the context of psychology, this refers to the time delay between responding to one stimulus and being able to respond to another.

1.2. There are two main types of refractory periods:
-Absolute Refractory Period (ARP): This is the period immediately following the activation of a neuron during which it is unable to respond to any other stimulus, regardless of the intensity. This period ensures that signals in the nervous system are discrete and do not overlap, providing clarity in the transmission of messages.
-Relative Refractory Period (RRP): Following the absolute refractory period, there is a relative refractory period in which the neuron can respond to a new stimulus, but only if the stimulus is of greater intensity than normal. This is a period where the neuron is recovering, and thus its responsiveness is reduced but not completely absent.

1.3. In cognitive psychology, the concept of PRP (Psychological Refractory Period) is used to describe the time during which an individual cannot respond to the second stimulus after having responded to the first stimulus, typically due to a cognitive bottleneck. This process happens when the brain is processing the first stimulus and cannot handle the second until the first task is complete.

1. Event Related Potential (ERP)
1.1. Event Related Potentials (ERP) are electrophysiological responses of the brain to external stimuli. They are measured by electroencephalography (EEG) and reflect the brain's electrical response to specific events or stimuli.
1.2. ERP helps researchers study brain activity and can provide insights into how the brain processes different types of information, including sensory, motor, and cognitive tasks.

2. Priming Effect
2.1. The priming effect refers to the psychological phenomenon where exposure to a stimulus influences the response to a subsequent stimulus, often making the individual respond faster to related stimuli.
2.2. Priming works by activating specific associations or concepts in memory, making them more accessible. This leads to faster processing when a related stimulus is encountered.
