ABSTRACT
Humans' information processing capabilities differ from one person to the other—the brain's compartment responsible for information processing in the left hemisphere and the right hemisphere. The right hemisphere is involved with perceiving global information, while the brain's left hemisphere determines local processing execution. An example of global processing is reading texts, while local processes identify and recognize details. Neuroscientist argues that the brain processes, including the global processes and the local processes, are significantly affected by introducing external factors, including caffeine, sleep deprivation, and multitasking incentives. Several studies including Mechanistic study, two-way ANOVA, paired sample t-tests, and Moderate/partial Sleep Deprivation studies are carried out to determine the effects of external influences including caffeine, sleep deprivation, and multitasking in cognitive functions and academic performances as illustrated herein.
Effects of caffeine in reading capabilities
Reading skills are largely affected by cognitive skills' function significantly concerned with the visual-orthographical and auditory-phonological connections and networks of the left-brain compartment. Significantly, the first point of focus for a word is its visualization. After visualizing a word, the visual stimuli are processed hierarchically from the brain's right hemisphere to the brains left hemisphere. The right hemisphere of the brain perceives the global aspects of the stimuli, including the scene's general view. After which, the left hemisphere analyses the most local aspects of this visual scene, including the stimuli' finer details. It is right to say that the left hemisphere and the right hemisphere play a pivotal role in the reading sequence. The global sequences analysis before analyzing the local including letters in a word and the whole word's analysis after analyzing the general sentence shape helps narrow down the local; aspects of the sentence to enable easy and accurate location of such candidates. Different studies show that the right frontoparietal areas form part of the necessary information processing, especially for conceptualizing complex patterns.
One of the most consumed psychoanalytic substance is caffeine. Caffeine inhibited the joining of the benzodiazepine and the adenosine to the nerve ending receptors, reducing the said ligand's inhibitory effect (Sandro et al., 2020). Especially, caffeine is said to counter the cognitive and physical effects due to sleep deprivation. The extent of the caffeine effect is more significant, with less depth to sleep loss. This caffeine is responsible for reversing the reduction effect caused by sleep debt, boredom, and muscular weariness. Caffeine has been observed to have mixed results on shorter-term memory, especially for oral and inscribed materials. Some of the cognitive capabilities that were not affected by caffeine include arithmetic capabilities, memorization of written content and writing speed. In determining the effect of caffeine in analyzing the correctness of a picture and reading a text, it was found out that caffeine enhances precision and speed. Caffeine is believed to facilitate the global identification process without necessarily altering the local apparatuses (Sandro et al., 2020). While looking at caffeine's effect on logical reasoning, caffeine is believed to improve the process of analyzing the global pattern, enhancing the identification of morphosyntactic desecrations when conducting a proofreading exercise. Contrarily, caffeine has no apparent effect on the ability to detect misspelt texts. Drawing from the study's above, including caffeine's effects on logical reasoning, local and global discernment, and lexico-sematic tasks, it is believed that caffeine could also have substantial effects on the reading tasks (Sandro et al., 2020). A study was conducted on such specific connections to understand the relationship between attentional-perceptual capabilities and reading improvements.
Materials and methods
A two mechanistic study involved the application of a repeated-measures and double-blind design. The function of the mechanistic study is to determine the apparatuses of action of interposition on cognitive enhancements (Sandro et al., 2020). This study seeks to find answers about how and not to confirm whether an intervention has an apparent effect. The mechanistic study seeks to provide answers concerning the accuracy of a hypothesis initially generated from a systematic and clear theoretical context to determine the extent of an intervention's effects on a particular cognitive process. In this mechanistic study, results from the first study measurements, including caffeine's side effect, are used to conduct a sample size definition for the second study. To attain this study's double-blind requirement, a bitter drink was used to facade caffeine's bitter taste (Sandro et al., 2020). The study performed across all the participants applied an orderly and counterbalanced administration of placebo solutions, also termed caffeine. The principle dictates of Helsinki's Declaration governed the unabridged investigation progression. All of the subjects' tough subjects issued formal informed written consents, while the HIT Ethics Committee of the Padua University approved all the formalities.
Participants
Twenty-four volunteers, including eighteen females and six males, participated in the first study. These volunteers were mainly wanted low consumers of caffeine. Participant tests were conducted between one- and seven-days difference. Scheduling of these evaluations was set at the same time in the morning hours (Sandro et al., 2020). The second replication study used twenty participants who are typical caffeine consumers, ranging from low to high consumption characteristics. The replication study participants received two tests performed after seven days following the first study's same design and procedures. Saliva samples were collected from the participants after thirty minutes of taking caffeine-induced beverage (Sandro et al., 2020).
Procedures and methods; the study evaluated reading and reading-related abilities using standardized reading tests, word text reading, pseudoword text reading, verbal long-term reading memory, rapid automized naming, and anxiety evaluation (Sandro et al., 2020). The replication study involved computerized reading tasks, single-word reading tasks, single pseudoword reading tasks, perceptual Navon tasks, attentional network tasks, and short-term phonological memory.  
Results
Evaluation of the reading skills from the first study indicated a possible enhancement in reading speed due to 200mg of caffeine consumption without necessarily affecting the error identification in the texts (Sandro et al., 2020). The reading capabilities were measured in syllables per second. There was confirmation of beneficial caffeine intakes' existence in word and texts reading speeds in the second replication study. The study established that participants' reading speed improved significantly after taking caffeine compared to placebo situations. This study also showed no apparent effect on the number of errors committed to reading (Sandro et al., 2020). From both two studies, it was established that a caffeine intake had no apparent influence on the lexico-long-term memory and the short-term phonological memory. Moreover, caffeine intake was linked to a more significant influence on the global extraction without any noticeable effects on the local processes.
The impacts of multitasking on executive functions, homework, and academic performance in Spanish adolescents
Multitasking refers to the continued urge to continue getting connected to multiple media devices due to the emergence of multi-function devices. The prevalence of this multitasking is linked to significant effects on homework execution, cognitive processes and the student's general performance I academics. Hence, a study aimed at exploring the relationship of multitasking, academic functions and executive functions. One of the probable causes for a rise in multitasking is the accessibility to information and communications technology. Multitasking can be differentiated into two distinct fronts, including simultaneous multitasking and multitasking while engaging in an activity that is not classified as media-related. The simultaneous use of multimedia devices is linked to several costs and befits, as illustrated by several literary works. Multitasking is a form of media application and is a common phenomenon among adolescents. Unrelate and parallel literature concur that there are tremendous impacts of multitasking on the execution of tasks if speed and accuracy are to be checked.
Initial research was carried out to determine the eventual impact of multitasking on the dispensing of multiple duties, focusing on the effects multitasking has on multitaskers speed and accuracy and their concentration while undertaking a particular task against multiple ongoing tasks (Maria de las Mercedes et al., 2019). This study also focused on developing strategies for continuous partial attention while receiving information from multimedia without necessarily concentrating on one particular source. Current research is focused on academic ...
