Le Chatelier’s Principle Questions In Part I the reaction you observed was Mg(OH)2 (s) → Mg2+ (aq) + 2 OH- (aq). Compare the colors you observed in the experiment and answer these questions: A. Which way should the equilibrium shift when HCl is added? How do your results support your answer? B.
Contrast Sigmund Freud’s view of human nature with the view of Abraham Maslow. With which, if either, view do you agree? 4. Altruism refers to behavior that helps others but does not appear to help the person performing the behavior. Describe an example of altruistic behavior, and state how a psychodynamic psychologist might explain the behavior.
They might operate in one of two ways when it comes to research, either as a “dependent variable,” or “independent variable,” it is usually known by either letters or numbers---A variable is anything that has the ability to change or vary in characteristics or properties. A variable commonly represents the unknown if my thinking is on track An “independent variable” also known as “predictor” variable, is a variable that can be manipulated or changed. In an experiment in order to observe the effect on the dependent variable and it can stand on its own. The dependent variable is uncertain as its outcome is reliant on the reaction of the independent variable---this is why it is called a “dependent variable” because it is dependent upon the “independent” For equations such as y = 3x – 2, the dependent variable is the “Y,” which depends upon the value chosen for “x.” On most occasions the dependent variable is normally isolated on one side of the equation. With the above equation the independent variable is the “X”.
Discuss the components of a naturalistic observation study. Compare and contrast case studies, surveys, and correlational studies in terms of descriptive research. 2.3 2.4 2.5 Describe the components of a psychological experiment. Illustrate the central tendency of, and the variation among, a set of scores in describing data. Describe what it means when a study shows an effect that is statistically signiﬁcant.
3. Research and experimentation help to support a theory or prove that it has no foundation. The threats to internal validity include, history, maturation, testing, instrumentation, statistical regression, differential selection and experimental mortality. The threats to external validity include, reactive effects of testing, self-selection, reactive effects of experimental arrangements and multiple-treatment interference. To control or eliminate these threats, controlled experiments are done.
Exercise 2: Testable Observations Determine which of the following observations are testable. For those that are testable: Determine if the observation is qualitative or quantitative Write a hypothesis and null hypothesis What would be your experimental approach? What are the dependent and independent variables? What are your controls - both positive and negative? How will you collect your data?
Baillargeon, Spelke & Waserman (1985) introduced a new method for testing infant knowledge- the violation of expectation method. Describe the method used by Baillargeon, Spelke & Wasserman, summarise their results, and state what the authors think the results mean. Finally, try to offer an alternative explanation for the results. Describe the method used by Baillargeon, Spelke & Wasserman Testing object permanence Baillargeon, Spelke & Wasserman (1985) used the violation of expectation technique to test object permanence in 5 month-olds. This was an indirect method which focused on the principle that a solid object cannot move through the space occupied by another solid object and did not rely on manual search as an index for object permanence.
Running head: THE SOCIAL ILLNESS OF METHAMPHETAMINE The Social Illness of Methamphetamine Abuse Abstract This paper discusses the causes and consequences of Methamphetamine abuse, and its affect on society. Presented is an overview of Methamphetamine dependency and a dialogue of three theoretical perspectives relating human development and drug addiction. The birth of Methamphetamine abuse has prompted federal and state governments to develop statutes, regulations, and policy changes to deal with this societal illness. Research of published literature and personal communication examines three legislative policies relevant to the misuse of this drug. A comparison of the policy models used in the development and implementation of these federal acts addresses the government's response to this public disease.
There must be criteria to go by that can prove whether the study is true or false. So we can start by making an observation and then posting a question to prove that observation true or false. Then, the hypothesis is used to make a guess on the outcome we think that the experiment will have. The third, and final step will be to test our observation and hypothesis and create data to come up with a conclusion for our study. The reason for having a hypothesis-based scientific study is because we do not know the outcome of something.
Philosophical and Practical Approach for Balancing Issues Philosophical and Practical Approach for Balancing Issues Individual rights are those principles that are held by a single person rather than an entire group. The rights of individuals can be mandated by the law, provided by social means, or gained through self-determination. These rights are generally associated with the concept of nature essentially; each person is born with rights that cannot be disenfranchised by the group. According to political scientists, individual rights can either be negative or positive. This means that a negative right allows the person to not act on a certain principle, while a positive right means that a person may act in a certain capacity if he or she wants.
