An increasing number of credible sources, however, underscore that multitasking is bad for concentration and learning (Borst et al., 2010; Manhart, 2004; Merrill, 2012). The paper intends to review literature regarding multitasking, memory, learning, and performance. My hypothesis is the following: Multitasking decreases the quality of performance because the human brain cannot do more than one thing that uses a similar cognitive resource; switching tasks decreases concentration; and multitasking is distracting and stressful enough to reduce the effectiveness of short-term memory, which is the basis for long-term memory.
Sources used employed different research designs. Borst et al. (2010) made use of a quantitative experimental research design to study if the problem state creates bottlenecks in cognitive processing when multitasking. They defined the problem state resource as important in storing intermediate information that is essential in performing tasks (Borst et al., 2010, p.364). Their conceptual model is based on Salvucci and Taatgen’s (2008) threaded cognition theory, which states that each task is done through cognitive threads and that cognitive threads are connected to task goals which mobilize related task knowledge (as cited in Borst et al., 2010, p.365). The theory asserts that, even when several threads may be activated concurrently, only a single thread can access the procedural processor of the brain (Borst et al., 2010, p.365). In other words, limited brain resources constrain the performance of multiple tasks. In their study, Borst et al. (2010) conducted three experiments: Experiment 1 included two concurrent tasks (subtraction and text entry tasks) performed by 15 university students; Experiment 2 and 3 tested if interference came from the problem state than cognitive load where Experiment 2 included alternative subtraction and

Dangers of Shift Work IV. Conclusion V. Works Cited Laura Walker 1 May 2011 Effects of Shifting Schedules to Circadian Rhythm I. Introduction A person’s sleep patterns are partly determined by one’s biological clock, or in more technical terms, one’s circadian rhythm (Miller 65).
Their main mode of subsistence is by pastoralism or the domestication of animals. Zulus make their livelihood from the products they derive from livestock such as sheep, goats, camels, alpaca, reindeer, and cattle. Thus, pastoralists depend on herding animals for their survival.
dies available to the victim; characteristics of the sex offender; and finally a literature review of sexual assault cases with an additional emphasis on cases where they are committed while the assailant and possibly the victim too is intoxicated with alcohol.
The source of these feelings was fear of the fact that the new technique would allow human cloning, and would allow for an unlimited number of genetically similarities.
The birth of the cloned sheep “Dolly” is an illustration of the ethical responsibilities of the
While the older generations are characterised by following the established rules, the younger technological generations question the existing protocols. Due to the issues that may arise as a result of differences in generations in the workplace, it is of great importance for
The early men who painted the animals made good use of color variation to bring out different effects on the painting. At the head of the stag, the artists seem to have used the red ochre color first and later finished it off with a dark color. That is particularly
