Subliminal Perception, Neuropsychology, and the I-Function :: Biology Essays Research Papers

Unconscious Processing: Subliminal Perception, Neuropsychology, and the I-Function In his 1957 book The Hidden Persuaders, Vance Packard warned the American public that "Large-scale efforts are being made, often with impressive success, to channel our unthinking habits, our purchasing decisions, and our thought processes... Typically these efforts take place beneath our level of awareness; so that the appeals which move us are often, in a sense, hidden" (1). Packard was convinced - perhaps rightly so - that advertisers were "professional persuaders" whose marketing techniques were deceptive and overly manipulative. Not only were advertisers becomingly increasingly adept at developing campaigns, pitches, and slogans to send specific messages to targeted consumer populations, but some had gone so far as to suggest that such messages could be effective even if they were presented below the level of conscious awareness. James Vicary, one of the market researchers and entrepreneurs profiled in Packard's book, claimed to have developed a machine capable of flashing such unnoticeable, "subliminal messages" within big screen movies. Vicary had allegedly tested his technique by altering movies so that messages urging viewers to "Eat Popcorn" and to "Drink Coke" were displayed at regular intervals throughout the film for such brief durations that they could not be consciously perceived. Vicary claimed that his subliminal messages resulted in a significant increase in sales of popcorn and coke (1). Although no experiment involving subliminal messages has ever replicated the success which Vicary claimed to have achieved and, in fact, Vicary later admitted that it had been no more than a marketing gimmick, the possibility of subliminal or unconscious perception has not been dismissed. In fact, although the use of subliminal messages is generally considered a foolish and invalid practice, the more general phenomenon of subliminal/unconscious perception deserves to be reevaluated in light of current debates surrounding the nature of consciousness. Subliminal or unconscious perception refers to the idea that stimuli presented below the threshold for conscious awareness can influence an individual's thoughts, feelings, or actions (2). The possibility that an individual can acquire and act on input without being aware of doing so has implications for the study of consciousness and the larger set of processes which characterize the I-function. It is generally assumed that that conscious perception of a stimulus is necessary in order to act on that stimulus, and this conscious decision to act is one of several processes which characterize the I-function.

Engineering Economic analysis Essay

Relevant psychological and physiological effects were found to occur in a promotion or transition process and these include the increased stress due to more challenging job experience and more demanding job responsibilities and the observation that the promoted technical person will become more people oriented and less technically oriented. The stress created could either result to positive or negative consequences to the just promoted manager. If positive, the promotion may make him or her happy in the job but if not the negative effects could result to the company not attaining its organizational objective. Motivational and leadership theories could be incorporated in the daily routine to the workplace but the their incorporation must take into consideration the assumptions and conditions under which theories may be applied in order to assure the company of a better chance of benefiting from their incorporation as people may react differently in a way that may contradict the intended purpose or purposes of the theories. It is an accepted business reality that people are the most important part of the organization but they are the same time the greatest liability if they are not motivated which makes it easy to attribute success or failure of the business to people and their decisions and actions. Applying or incorporating the theories is possible but requires a great deal of challenge to management because it is difficult to determine with certainty the different conditions under which the theories and motivations and leadership may apply. In however making the decision to incorporate the theories into the daily routine of the workplace, advantages could be found in the greater chance of having motivated employees that would help the organization in attaining its vision but at the same time disadvantages are also inevitable for incorporating the same on the basis of the risk of making decisions to incorporate for not all incorporations of theories will result to a successful end. This paper asserts that certain foreseen and relevant psychological and physiological effects may occur in a promotion or transition process of technical person, using another person’s personal on-the-job experience, and the managerial visionary concepts covered/discussed in both MSE504 (Engineering Management and previously MSE404) and MSE602 (Advanced Engineering Management.) This further asserts that incorporating the theories of â€Å"Motivation and Leadership† into the daily routine of the company (workplace) from the perspective of engineer advancing in positions and that of an accomplished engineering manager is not easy as the theories are applicable under different set of assumptions or conditions which the present company does not readily lend without effecting changes to the higher corporate strategies of the organization. It is further asserted that in so incorporating the said theories touches upon different pertinent theories and job-related experiences that cover key attributes of management such as: risk-taking and decision-making, judgment by trial and error, performance monitoring and evaluation, observation and interpretation, strategizing and behavioral analysis and that in so having various effects among these attributes of management, advantages and disadvantages as well as ramifications could be observed as they personal conduct, overall managerial tasks, and the company’s operational vision.

Business Survival in a Recession Essay

The key to business survival in recession is leadership† To what extent do you agree with this view? There are many different ways in which a business can use techniques to survive in a recession and here leadership is the key focus. To explain fully I will be focusing upon such ideas as the type of leadership management used, motivational effects where a business motivates the demoting factors such as ‘cuts’, for example sack employees to reduce costs that may viable save a business, the role of leaders in setting about change and management in bringing about the idea of change/ new instructions. Yet as well as the positives there are the negatives to a leadership styles and how its managed within a recession, so such factors as limited resources from change, an example being the reduction in the workforce size, the role of stake holders that ask the questions whether one leader is enough in a recession in comparison yet the leadership throughout the whole organisation. Particular business example such as ‘British Airways’ and ‘Sainsbury’ case studies and finally the external factors that inhibit a business chances for survival in a recession. Most certainly one of the most relevant points to make about a business trying to survive in a recession is the type of leadership management that is in place. For a success full leader and many styles can be used in times of desperate measures; here I would suggest during a recession that an Autocratic style of leadership needs to be followed, clear expectations for what needs to be done, when it should be done, and how it should be done. Although for the short term this aggressive direct approach needs to be considered to get a business through the hard times it had to face. For example with Margret Thatcher who was in power during the last recession in the 1990’s had to use this style of leadership to get the country out of the problem, yet left certain problems in doing so. If this is not to be the most productive method of leadership during a recession managers may adopt the Democratic leadership style where leaders offer guidance to group members, but they also participate in the group and allow input from other group members. Although the type of leadership is successful in producing high quality it is less productive than that of an Autocratic leadership style. Motivational factors are essential for a business survival in a recession whether it’s for the employees/ staff or the customers who have the purchasing power. Both these groups need to be aimed at by the higher authorities of a business to allow for a good circular flow of income to keep the business stable in hard times such as the recession. Although this motivation may comes in many different ways some being bad and the others being good, for a business such motivational factors as making ‘cuts’ and redundancies of employees to allow for a business to keep up with costs will see demotivation amongst labour workers but may see improvement in the costs in which they have to pay. Reduction of stock and capacity utilisation will see a lower work ethos, as less produce will be produced. By not overstocking and hoping that it will sell a business may have to adopt a ‘JIT’ or just in time method of production to satisfy orders the have at present rather than in the future. So here leaders/ managers must make the decisions to implement whether to make the changes needed to allow the business to survive for the time of the recession or maintain their current workforce and level of stock and hope the business is successful and can still sell their products. The introduction and bringing around of change is in some cases problematic for a business in terms of the employees views of change and valid in times where its essential to keep the business floating. Such examples as General motor’s, IBM, and Sears are ones that need pushing for organizational improvement, whether they are external members of the board, major investors, or top executives; they must deal with cultural and behavioral obstacles to change. Specifically, attempts at organizational change must consider three key features of organizational life: the firm’s culture, the leadership of the change effort, and the existing network of power. Company culture is important because it can make or break a company. Companies with an adaptive culture that is aligned to their business goals routinely outperform their competitors. Company cultures evolve and they change over time. As employee leave the company and replacements are hired the company culture will change. If it is a strong culture, it may not change much. However, since each new employee brings their own values and practices to the group the culture will change, and with this could include different motivational factors and views of other workers; so its vital for a business to include employees and workers in the changes a manager/ leader may wish to implement so such things as strikes and revolts do not occur. The roll of stakeholders in a business is essential as they can decide where a business should go and what should be done during times of recession. Here employees, investors, sharholders, customers and suppliers are all stakeholders that need to be satisfied in order for them to continue to invest within the business to keep it running. Employees should all see where the business is heading, and where it is heading towards otherwise they might see little point in changes in changes that have been made and may become suspicious. It is very important that the changes are explained clearly to employees and that any fear they may have are properly addressed. Investors are important because the business relies on their investment to finance the decisions that it takes. They may become worried that the business has no overall direction and look for other places to put their money. If they are unhappy this could leave the business weakened and prone to take-over. Shareholders are interested in any decision that effects the dividends that they receive is their share of profits. Any decision that will reduce profits, even for a short while, will not be popular with the shareholders. So here the managers of the business would want to avoid this in such poor economic times, so they would have to consider how shareholders will feel about the decisions made. Customers will be concerned if the decisions affect the price, quality, or service of the product they may change their buying habits if the product does not meet their requirements. Suppliers will want to get regular orders with prompt payment, these may be effected by the decisions made by the business. To conclude I do feel that the key to business survival in recession is leadership. For example a business that had a bad leadership style during the recession was British Airways where Willie Walsh’s decisions where poor communication amongst the companies stake holders saw strikes and grounded airlines. With the limited flights due to the poor leadership the business has lost a large amount of profits and the costs the company has to pay in order to compensate customers; the company now and is still in problematic times to regain the motivation and reassurance of the customers.

metallic conductor essays

metallic conductor essays Determination of r for a Metallic Conductor To determine the resistivity (r) of a given sample of wire Physical factors that affect the resistance of a conductor are length, cross sectional area and a constant that depends upon the material called the resistivity. The resistance per unit length is the same all along a uniform wire so if the resistance of different lengths of a wire is found out, the resistivity can be calculated. Resistance of a material, R = Voltage Current Resistance of a conductor, R = r Ãâ€" Length Cross sectional area - given sample of wire ( 5 m) - variable resistor is used to alter the resistance to change the current and voltage for each length - ammeter the 5 ampere outlet was used since the current was generally over 1 amperes - voltmeter the 5 volt outlet was used because voltage was always below 5 volts - meter stick more appropriate than a 30 cm ruler because the length is changed by 50 cm each time - micrometer since the wire is very thin an accurate measurement of the diameter can be obtained by using a micrometer with an uncertainty of 0.0005mm. 1. Set up the apparatus as shown on the diagram. 2. Make sure the voltmeter outlet is at 5 volts and the ammeter outlet is at 1 amp. 3. Measure 50 cm of the wire using the meter stick. 4. Connect this part of the wire to the circuit using the crocodile clips. 5. Make sure the wire is not touching other parts of the wire. 6. Turn the power supply on, record the voltage and current. 7. Using the variable resistor, alter the resistance and take 4 more different readings of voltage and current for this length. 8. Repeat steps 4 to 6 for 5 more times, each time increase the length of wire by 50 cm using the meter s ...

How Salt Melts Ice and Snow

How Salt Melts Ice and Snow If you live in an area with a cold and icy winter, you have probably experienced salt on sidewalks and roads. This is because salt is used to melt the ice and snow and keep it from refreezing. Salt is also used to make homemade ice cream. In both cases, the salt works by lowering the melting or freezing point of water. The effect is termed freezing point depression. How Freezing Point Depression Works When you add salt to water, you introduce dissolved foreign particles into the water. The freezing point of water becomes lower as more particles are added until the point where the salt stops dissolving. For a solution of table salt (sodium chloride, NaCl) in water, this temperature is -21 C (-6 F) under controlled lab conditions. In the real world, on a real sidewalk, sodium chloride can melt ice only down to about -9 C (15 F). Colligative Properties Freezing point depression is a colligative property of water. A colligative property is one which depends on the number of particles in a substance. All liquid solvents with dissolved particles (solutes) demonstrate colligative properties. Other colligative properties include boiling point elevation, vapor pressure lowering, and osmotic pressure. More Particles Mean More Melting Power Sodium chloride isnt the only salt used for de-icing, nor is it necessarily the best choice. Sodium chloride dissolves into two types of particles: one sodium ion and one chloride ion per sodium chloride molecule. A compound that yields more ions into a water solution would lower the freezing point of water more than salt. For example, calcium chloride (CaCl2) dissolves into three ions (one of calcium and two of chloride) and lowers the freezing point of water more than sodium chloride. Salts Used to Melt Ice Here are some common de-icing compounds, as well as their chemical formulas, temperature range, advantages, and disadvantages: Name Formula Lowest Practical Temp Pros Cons Ammonium sulfate (NH4)2SO4 -7 C(20 F) Fertilizer Damages concrete Calcium chloride CaCl2 -29 C(-20 F) Melts ice faster than sodium chloride Attracts moisture, surfaces slippery below -18Â °C (0Â °F) Calcium magnesium acetate (CMA) Calcium carbonate CaCO3, magnesium carbonate MgCO3, and acetic acid CH3COOH -9 C(15 F) Safest for concrete vegetation Works better to prevent re-icing than as ice remover Magnesium chloride MgCl2 -15 C(5 F) Melts ice faster than sodium chloride Attracts moisture Potassium acetate CH3COOK -9 C(15 F) Biodegradable Corrosive Potassium chloride KCl -7 C(20 F) Fertilizer Damages concrete Sodium chloride (rock salt, halite) NaCl -9 C(15 F) Keeps sidewalks dry Corrosive, damages concrete vegetation Urea NH2CONH2 -7 C(20 F) Fertilizer Agricultural grade is corrosive Factors That Affect Which Salt to Choose While some salts are more effective at melting ice than others, that doesnt necessarily make them the best choice for a certain application. Sodium chloride is used for ice cream makers because its inexpensive, readily available, and non-toxic. Yet, sodium chloride (NaCl) is avoided for salting roads and sidewalks because the sodium can accumulate and upset the electrolyte balance in plants and wildlife, plus it can corrode automobiles. Magnesium chloride melts ice more quickly than sodium chloride, but it attracts moisture, which can lead to slick conditions. Selecting a salt to melt ice depends on its cost, availability, environmental impact, toxicity, and reactivity, in addition to its optimal temperature.

Report - Usability and Anthropometrics for ROWENTA Intensium Bagless Assignment

Report - Usability and Anthropometrics for ROWENTA Intensium Bagless Vacuum Cleaner - Assignment Example By the end of the report a clear evaluation of the appliance achieved by experimenting it with users will be covered. The report also offers an analysis of performance in regard to ergonomic principles. Although, it is widely thought that bag-less vacuums were developed just the recently, the features have been in use since time immemorial.  The previous vacuums, for example used bag-less qualities until about three decades ago, when the feature was discarded.   The manufacturers abandoned making bag-less vacuums on hygienic grounds.   The usability of such appliances was low.  One had to remove the bag part off and empty the dirt in the garbage. This was a daunting task, especially when a dustbin or refuse disposal was not near.  Additionally, the appliance’s use over time would result in the clogging of the filtration in the bag, following more dust accumulation (Gavriel, 2012). Most users were prompted to wash the cloth bag in order to achieve adequate efficiency when the cloth had become dirty.  The current world has, however, seen the comeback of the bag-less vacuum. Rowenta Intensium Bag-less Vacuum Cleaner is arguably one such equipment that is as well-lik ed as before due to its effective usability qualities. According to Gavriel (2012), the primary reason behind the widespread use of the appliance is that one does not need to purchase vacuum bags to operate it. This implies more savings on the part of the user.  Additionally, as the chamber in which dirt collects becomes increasingly filled with dirt, it should just be removed and emptied in the refuse bin.  Another advantage of using the Rowenta appliance is that any more accumulation of dirt in the chamber does not impact its continued functionality, and that one can practically read the amount of dirt being absorbed by the vacuum cleaner, hence the ease to tell whether the appliance is functioning well, and the level of dirt
