3. a) What does it mean to manipulate a variable? b) What does it mean to control a variable? c) What is the difference between a controlled variable and a control group? a) To manipulate a variable is the ability to turn a potential cause on or off willingly. b) To control a variable is to make it so the variable cannot influence the experimental results.
It should also be noted that the author has created a substantial false dilemma around this situation, noting that if money is not spent on something, than it must be perceived as unimportant. Although the premises do not necessarily support the conclusion, they are plausibly true. The U.S. Department of Justice (2009) and the Fatality Analysis Reporting System (2008) both indicate that yes, the number of deaths related to murders and fatal car crashes are higher than the number reported dead or missing from
The term eyewitness testimony (EWT) is actually a legal term, referring to the use of eyewitness (or earwitness) to give evidence in court concerning the identity of someone who has committed a crime. Psychologists tend to use the term ‘eyewitness memory’ instead of ‘testimony’ when carrying out research to test the accuracy of eyewitness testimony. Loftus and Palmer (1974) were interested in the accuracy of memory after witnessing a car accident, in particular to see if leading questions distorted the accuracy of an eyewitness’s immediate recall. Forty-five students were shown seven films of different traffic accidents. After each film the participants were given a questionnaire which asked them to describe the accident and then answer a series of specific questions about it.
The person who commits hate crimes will most likely plan their attack more so than someone who just commits crime on a regular basis. Often younger white males between the ages of 16-25 dominate in hate crimes. Hate
Officer found that their was sufficient evidence to prove charges. QUESTIONS PRESENTED Whether reasonable suspicion existed to permit officers to conduct a brief investigatory stop of the car in which the defendant was the passenger Whether the evidence is sufficient for a jury to conclude that the defendant and his fellow perpetrator planned and intended to kill the victim, and that the defendant’s conduct constituted a substantial step
Our memory in effect shapes our reality and this is the basis of Elizabeth Loftus’ research. In her experiment she selected a random assortment of people and subjected them to footage of a car crash. She then asked a variety of questions relating to the speed of the vehicles before the incident. From this, Loftus concluded that the speed the participant thought the vehicle was going changed depending on the way the question was phrased. For example, when she asked, “how fast was the car going when the two cars smashed?” the participants gave a much higher speed than when the question was phrased, “how fast was the car going when the two cars collided?” This research created a lot of skepticism over the accuracy of eyewitness accounts and since then DNA testing has found a lot of convicted felons to be innocent.
1. What is the significance of the title? In the begining of the movie there was crime scene which shown a car crash, the word "Crash" is symbolic for the culture shock we experience when in our everyday lives we "crash" into people from many different races, religions, and nationalities. The movie brings out the assumptions we have about ppl from different cultures with whom we interact in the course of our daily lives. 2.
Rigor and control of extraneous variables allow researchers to establish a cause-effect relationships testing casual relationships (Polit and Beck, 2012).Experimental designs strengths are that a researcher gains first hand knowledge based on the use of actual tests and trials. The weaknesses are that outcomes may not be the most desirable and may be cause for a major effect up to the death of a patient. There is also the subject of ethics, how much exposure to experimental research is considered enough or is justified. Nonexperimental design Arnold (1997) comes in many forms and generally refers to research that does not employ randomization and control groups (p.44) .This is a non intrusive way to research. Based on actual fact and findings one can discover the actual results needed.
The ad is a picture of a child with a dent in her head that looks as if she is made of car metal. In the corner of the ad it says “In town, car accidents don’t just happen to cars. Slow down.” The intended audience is most likely drivers who speed through neighborhood areas. Clearly the ad is to prevent car accidents by telling drivers to be cautious and slow down when driving, especially in local areas or “in town” where kids play. With this ad, the strongest appeal to the audience is clearly pathos, or appeal to emotion.
After finding out that one of the suspects was detained, I would take each witness over to the squad car and let them have a chance of seeing if that is one of the suspects. (Without the suspect seeing them of course). This would also determine whether to make a preliminary arrest and would also justify a search of the suspect’s car and property. While still at the liquor store I would view all surveillance videos and try to see if the suspect detained is caught on videotape or at least try to see if his height and build match Next, what I would do is put the suspects in a lineup and have the witness/victim make a positive identification. Before the lineup is done, whether physical or photo, you have to explain to the victim/witness that the purpose of the lineup isn’t only for identification but to also exonerate the innocent.
