Essays on Accuracy

I selected speed and accuracy as my topic because both abilities are critical in the majority of popular sports today and useful in many other movement-based skills. However, speed and accuracy often contradict each other, so it is hard to execute together. Most models and research papers consider those two abilities opposite and emphasizing one should result in trading off the other, and Fitts’ law explains that target size and movement distance are the factors responsible for that trade off.
Although there are apparent tradeoffs between speed and accuracy, a better understanding of both abilities and how they can Continue reading...

Over the years, many people either win or lose cases as a result of the information provided by the witnesses given a chance to testify against them or in their favor. It is true that human being is prone to forgetting. As a result of the many activities they are engaged in, it becomes necessarily inevitable for individuals to retain all that they have heard or seen throughout their lifetime.

Similarly, there have been a lot of rumors based on stereotypical beliefs that the more elderly a person is, the more they lose their retention credibility. It is therefore, Continue reading...

Human body is made of senses that humans use in everyday activities to determine perception of data and hence make decisions. The perception has several reasons that help the humans to belief in the accuracy and inaccuracy of the perceived data. There are five reasons of believing in the accuracy of the data. These include, touch, and smell, hearing, taste, and sight.
When one touches something, the sense determines the perception. This can either be cold, hot, rough, smooth, etc. the message is automatically sent to the brain for interpretation. The brain then determines the mode of reaction to Continue reading...

Validity and Scope of Approximate Methods of Integration

Introduction
Addition of discrete numbers is pretty straightforward; more than 80% of the human population can make mental calculations instantly. So when integration was introduced as a kind of addition in a continuous domain, I was not very worried. However, it didn’t take me long to realize that understanding integration is more than solving a bunch of problems using well defined techniques. So in my pursuit to understand the topic well, I decided to research upon how some of these techniques (Trapezium Rule and Simpson’s Rule) came about, how they work, and what they really mean. With Continue reading...

Reasons for Believing in the Accuracy on Inaccuracy of Sensory Information

If fortunate enough, we are born with all the five senses which are touch, sight, hearing, taste, and smell. These senses help us to perceive our environment and are the basis on which we go about our daily activities. We eat, listen, look, smell, and feel, and this is made possible by sensory perceptions. There are three reasons for believing in the accuracy of sensory information. One is the aspect of sensory interaction. Different senses work together to create an experience. For example, taste, texture, and smell combine to create the flavor that we experience in food. Another example Continue reading...

Many decisions made in operation management are based on forecasts. This is the basic principle used in matching supply to demand. A company’s accurate forecast enables it to take advantage of future opportunities and decrease on any impending risk (Stevenson 109). Forecasting is basically an anticipation of an event in the future. In business, entrepreneurs need to forecast or make a valid anticipation of what a customer will want to buy. In operations management, forecasting is a way of getting information on what a customer will demand in future. This is a way of aligning the supply according Continue reading...

Introduction

A lot about who we are is due to our sensory perceptions. Our actions and inactions are determined by the information processed in our brains. This information is input through the sensory pathway. It is through this way that we connect to the physical world. Many scholars have argued that that which is not first in the senses is not in the mind. Nonetheless, the importance of sensory perceptions in shaping who we are individually does not vouch for their accuracy or inaccuracy. Sensory perceptions are not always accurate as evidenced by incorrect interpretations of the sensory data input Continue reading...

Abstract

A 'mirror-tracing task' (or mirror-tracing test) is a psychological test used to measure a variety of functions such as learning, transfer of information from one brain hemisphere to the other, and other perceptual/motor skills. In the test, two hypotheses were formulated in a bid to understand the concept of spatial perception, transfer of abilities and gender differences. On the first hypothesis, Continuous exposure to the mirror-tracing test will lead to improved mirror tracing skill; we needed to look at the influence of practising on the mirror tracing skill. 243 subjects were continuously exposed to the Continue reading...

Establishing whether human senses and sensory data can be relied on in providing an accurate view of the world is highly controversial. This is because human senses often have the potential of providing accurate interpretation of our environment. Similarly, human senses present some detrimental weaknesses that affect their ability in the interpretation of sensory data. The paper examines the reliability of the human senses and interpretation of sensory information.

Reasons for Believing in the Accuracy of Sensory Data

The first the rationale for believing in accuracy of sensory information is based on the process through which humanity perceives experiences. Barth, Patrizia, & Klein, (2011) identifies perception as a sensory Continue reading...

Introduction

Accurate and precise measurements are of uttermost importance to chemists everywhere. A measurement is said to be accurate when it is very close to the accepted value. A precise measurement is one in which repeated measures yields values or figures that are very close to one another. However, not all measuring instruments have an equal ability to give accurate and precise measurements. In any given experiment, the techniques and the equipment used to collect data should essentially be of the same precision. In the course of an experiment, there are bound to be less precise measurements and it these Continue reading...

Impact of using lowly-differentiated Stimuli on the Working Memory

Abstract
Sternberg Paradigm has been used as a measure in short term memory studies since the model was developed in 1966. Several subsequent studies have, however, not being successful in duplicating the exact results achieved by Sternberg. The reason for this has been identified as the other researchers’ use of faster stimulus presentation rates. The results from these subsequent studies indicate the impact of the presentation rate on the recall capability of the working memory. It is essential to highlight that all these studies used highly differentiated stimuli. This study will, however, analyze the impact of using lowly differentiated Continue reading...

Abstract

Research can be carried out through primary or secondary methods. While the secondary methods are cost effective and convenient, they lack the accuracy and currency in terms of contemporary occurrences. It is for this reason that researchers embark on field surveys where they sample a group of respondents from the population collect primary data from them and extrapolate to reflect a representation of the entire population. However, the use of questionnaires and a cross sectional study approach comes with its own unique strengths and weaknesses. It ensures the research objective are adhered to and that the relevancy is not Continue reading...

Every human being has five external senses, namely hearing, sight, smell, taste, and touch (Bos and Read). These five sensory inputs determine how we interpret and understand the world we live in. We can define sensory perception as the process in which we use these five senses to receive stimuli, interpret and organize them in order to understand the meaning the environment around us. It is because of sensory perceptions that we are aware of our immediate surrounding by interpreting sensory information for survival purposes (Brewer, 2002).
Personally, I believe that sensory information is not accurately interpreted by the Continue reading...
