Download file to see previous pages Task switching is the sequential representation of one task after another, a concept that is commonly referred to as psychological refractory period abbreviated as PRP. The time taken in measuring the response to stimulus of task in classical psychology is known as refractory period measured using dual task paradigms. When describing PRP paradigm, one should first present a stimulus (S1) for the first task (T1) before presenting the stimulus (S2) for the second task (T2). Stimulus onset asynchrony is the duration between the onset of the two stimuli. When there is smaller distance between the two stimulus, the S2 will have a longer reaction time (RT). The reaction time is measured for both the T2 and T1. Jersild (1927) argued that the reaction time for S2 has to be shorter the first task than it is for the second task. The main challenge for most current studies is the absence of task repetition, which was part of the study applied by Jersild (1927) who used PRP and pure task condition.
There are other concepts ascribing that the concept of multitasking leads to multitasking madness because it waste time. Multitasking madness was described as the capability of human brains appearing as though performing several tasks at the same time yet it uses its filtering mechanism to make it possible to switch from one task to another (). In fact, the multitasking myth is a common phenomenon when assessed from the daily activities and events. For instance, it is possible to find people walking while talking or driving cars while answering mobile phones. Avoiding multitasking madness requires that the individuals estimate the time required to perform a task precisely to avoid underestimation of the required time, which may create bias expectations that would turn unrealistic expectations in the performance (). Besides, the concept of letting off the external memory is important because it reduces the cognitive load that helps the individual to have ...Download file to see next pagesRead More

Nowadays, multitasking has broadened to include human multitasking. Many people, especially in this information age believe that a person’s brain can...

...? Theoretical Paradigms Introduction Various scholars advanced different theories describing how society functions. Functionalistssuch as Talcott Parsons and Emile Durkheim viewed society as a collection of interdependent functions held together by social consensus. They posited that the destabilization of one function destroyed the society’s state of equilibrium and directly affected the functioning of other functions; for example, political unrest in a society elevates tension among people and negatively influences the society’s economy. On the other hand, proponents of structuralism (created by Ferdinand de Saussure) best understood society’s functioning through the examination of underlying structures such as language...

...of social structure, it emphasizes social differences, rather than social integration. Competition plays an important rule in that it creates social change. Lastly, the symbolic-interaction paradigm is a framework for building theory that sees society as the product of the everyday interactions of individuals. It focuses on how people define reality and how they reconcile it with their experiences. It works on the assumption that structures are formed through interaction such that behavioral patterns and norms are developed, thereby providing a means of interpreting actions and speech. The above-mentioned perspectives apply to various social structures. Using the structural-functional view, deviance is...

Multitasking

...MULTITASKING Introduction Prior to the introduction of multitasking, the early programs used to run in batch mode on computers, i.e. once a particular program was initiated it continued execution till the batch of instructions was completed. User interference was not allowed or possible while the batch was running, since two programs could not run simultaneously. However, after continuous research a new function, called multitasking was developed whereby multiple programming could be facilitated on the same machine. It enabled the programmers / users to run multiple tasks at the same time, by allowing two or more programs complete access to the system, in the batch mode....

The two illustrated that it is challenging or even impossible to acquire new information when multitasking. Multitasking negatively influence academic performance. This shows that learners who participate in high multitasking levels experience challenges in their academic work. Recent studies of influence of multitasking on academic performance illustrates that using the social media when studying negatively affects student grades; but online searching did not (Steven, Adam & Arturo 1313). The brain cannot completely focus during multitasking. Hence,...
