PsychSim 5: Hunger and the Fat Rat 53 PsychSim 5: HUNGER AND THE FAT RAT Section: 1 Date: Thursday‚ July 11‚ 2013 This activity provides a simulated experiment on weight regulation in rats. The Hypothalamus * What are the two techniques used to study hypothalamic dysfunction? How do they differ? The two techniques used to study hypothalamic dysfunction are stimulation and destruction. To simulate the hypothalamus a small wire probe is inserted into

Normal psychology is the study that gives focus on the normal or average human behavior according to the socially acceptable behaviors‚ practices and traits. In contrast‚ abnormal psychology is the study that deals with unusual human behaviors that people deem are against the socially accepted behaviors and that includes mental disorders. Differentiating the two however‚ needs careful study because it involves human judgment which may or may not be necessarily correct. To aptly define and contrast

conditioning in rats. The purpose of the experiment was to condition rats to suppress certain hunger behaviors such as water licking. Burdick and James paired the neutral stimulus of white light with shock in a “test chamber” to see if rats would develop an association between the two stimuli. Naturally‚ shock induces a fear-like freezing behavior‚ and after being conditioned the rats displayed the same behavior but only to the white light. Furthermore‚ they would then place the rats back in their

Normal Distribution:- A continuous random variable X is a normal distribution with the parameters mean and variance then the probability function can be written as f(x) = - < x < ‚ - < μ < ‚ σ > 0. When σ2 = 1‚ μ = 0 is called as standard normal. Normal distribution problems and solutions – Formulas: X < μ = 0.5 – Z X > μ = 0.5 + Z X = μ = 0.5 where‚ μ = mean σ = standard deviation X = normal random variable Normal Distribution Problems and Solutions – Example

ball is thrown upward at time t=0 from the ground with an initial velocity of 18 m/s (~ 40 mph). Assume that g = 10 m/s2. Time to reach apex 18/10 = 1.8 Time x 2 = 3.6 Great height reached by ball – (Velocity)(time)+(-5)(time^2) 18x1.8+(-5)(1.8^2)=16.2 A model rocket accelerates upward from the ground with a constant acceleration‚ reaching a height of 63 m in 8 s. * Speed at height 63 - 2x63/8 = answer What is the acceleration= answer/8 * If you were to drop a rock from a tall building

Communism is a system where there is no private ownership of business or property and the country’s wealth gets shared among the population. Vladimir Lenin started the communist international which was an organisation with an aim of spreading communism throughout the world. Communism really was a threat to Australians in the 1950s‚ the events of the Korean War‚ different alliances being formed‚ the banning of the Communist party of Australia (CPA) and the Petrov affair all tell us that communism

What is normal? Normal‚ like the word love‚ has no true definition and will differ with every person you ask. Defined in the dictionary normal is “to conform to a particular standard” or “desired pattern”. I believe most people will say a normal person is one whom is free from defect‚ handicap and mental illness. Medicalization is a social process through which a previously normal human condition whether is be behavioral‚ physiological or emotional‚ becomes a medical problem in need of treatment

NORMAL DISTRIBUTION 1. Find the distribution: a. b. c. d. e. f. following probabilities‚ the random variable Z has standard normal P (0< Z < 1.43) P (0.11 < Z < 1.98) P (-0.39 < Z < 1.22) P (Z < 0.92) P (Z > -1.78) P (Z < -2.08) 2. Determine the areas under the standard normal curve between –z and +z: ♦ z = 0.5 ♦ z = 2.0 Find the two values of z in standard normal distribution so that: P(-z < Z < +z) = 0.84 3.

research Do women’s ideas of ‘normal’ birth match those held by professionals? Abstract Aim: To explore the definitions of normal birth held by women who have not given birth‚ what influences that perspective‚ and compare it with those of health professionals. Background: Available evidence provides conflicting definitions of normal childbirth. The majority of available evidence encapsulates the views of the health professionals themselves or women who have experienced childbirth. Little evidence
