The mean number of correct responses as a function of time-delay and type of questions are presented in Table 1. A 2 ([time delay: 0 min. v. 5 min]) x 2 ([type of questions: leading v. non-leading]) between-subjects ANOVA was performed to evaluate the effect of time-delay and type of questions on recall accuracy. The analysis showed a marginally significant main effect of leading questions, (F(1, 47) = 3.44, p = .07), and no main effect of type of questions (F(1,47) = 1.08, p > .050), and a no significant (time delay x type of questions) interaction (F(1, 47) = .085, p > .05) .


The experiment was conducted to evaluate the effect of leading questions on eyewitness accuracy. We predicted that if participants were presented with leading questions, number of correct responses on the recall test following the leading questions would decrease. The results of this study did not replicate the findings in earlier work by Loftus (1975), in showing that leading questions did not significantly decrease accuracy on the recall test in both a time-delay and no time delay conditions. There was little difference in recall of the existing object and the difference was not statistically significant.

A factor which may have influenced our finding is that the staged-event witnessed in the experiment was not exactly the same for all conditions. Because this experiment used the real-life event instead of a video tape, it was difficult to duplicate the event the exact same way for all conditions. In addition, a substitute confederate was used in one of the conditions due to the unavailability of our confederate.

Although, the findings were not consistent with previous studies, it is important for future researchers to further examine to see how well the results of previous studies indicate real world effects. If the results…...

Results/Analysis of Diffusion Lab

...**IF YOU ARE USING THIS** please note that this was an experiment conducted by me and my lab partner. Due to the fact that she wrote the materials/methods section and the abstract, I have not included it. This is only results and analysis for a diffusion lab for a Biology400 college class. Please do not copy and paste, it is PLAGIARISM. Only use for clarification of analyzed results. Results Figure 1a. The following table includes the circumference of the circle that was created by the diffusion of three separate dyes. It also includes their molecular weight. The chart shows that Potassium Chromate diffused much more than the Methylene Blue and the Congo Red, both in the refrigerated gelatin and the room temperature gelatin. The Methylene Blue has the second lowest molecular weight, and diffused more than the Congo Red as well. The results also show that, with the exception of the Potassium Chromate, the dyes in the refrigerated gelatin diffused at a slower rate than those in the room temperature gelatin.

...Good morning/afternoon teachers and students we are here today at the HSC Study Day to discover and analyse the ideas and characters which are always centralised in films. Centralised in a matter of "Distinctive characters and ideas are at the heart of every film". Furthermore the film “Witness” directed by Peter Weir delves into the concept of the themes and characters. In Peter Weir’s western showdown the metamorphose of clashing cultures are highlighted through his use of a variety of cinematic techniques. The cascading use of lighting and sound in the “Barn Dancing Scene” is used to symbolise the romantic tension between Book and Rachel. Through angling the camera of the car and upper mid shots of both Book and Rachel when they are inside the car and as they exit the vehicle, Weir zooms into Rachel’s face which is comprised with shock followed by a smile. By doing this Weir is able to manifest the notion of romantic tension between his two characters by confronting his audience with a situation that demonstrates Book’s growing fondness of Rachel. The use of soft and ever-present sounds is utilised to demonstrate the innocence of his characters emotions. Furthermore by applying these techniques the audience is pulled into a world which exacerbates the social regulations that may prohibit the growing relationship between Book and Rachel. This has a profound impact on the audience the rigid culture clash becomes ever more evident which Weir does purposely to expose his......

Eye Witness Testimony Case Study Essay

...and problems with the EWT used in this trial: firstly, at the first interview there was some inconsistency in the group’s descriptions of the robber (2 said he had brown hair and 2 said he had blonde hair), this shows a problem with the EWT used in the trial as clearly straight after the event (the eye witnesses memories of the event would have been the clearest as it had just happened), however as they were interviewed in a group all 4 members of the group heard what the others had to say about the event- subsequently two of the witnesses changed what they said and thus all four claimed he had blonde hair. This is a clear problem with the testimony used in the trial as as all the witnesses were interviewed at the event in a group and due to social desirability and conformity they changed their remembrance of the event- therefore what they said in court may have not been an accurate account of what they think they actually saw. Weapon focus may also have had an effect in this case and this would have also caused a problem with the EWT used as the criminal used a weapon, and as that weapon is a threat to these people’s lives then they would have focussed on that weapon, and as a result this would have distorted what they remembered about the rest of the event (i.e. what the criminal looked like) which makes the EWT used invalid. The police in the investigation did also lead the witnesses to a desired answer as in the third interview they showed them a picture of James......

...Module B – Witness Peter Weir uses his film witness to express his concerns with the modern world by looking at the binary opposition of the Amish and western society. The Amish represent the old world and it is seen that they live peacefully while our modern world is filled with violence and corruption. Using the themes of conflicting cultures, violence vs. pacifism, and technology vs. tradition, weir is able to explore the conflicting cultures of the Amish and the English. American society is represented as a violent and arrogant group of people, whereas the Amish are seen to be a peaceful and religious group of people Witness presents two very different worlds. Peter Weir can demonstrate this in the opening scenes as he uses a variety of techniques to emphasize the difference between the people of the Amish and the modern world. The unified Amish, dressed in their old fashioned clothing, walk through a picturesque landscape to a funeral. The audience is led to believe that this is a historic film but the world ‘Pennsylvania 1984’ appear on the screen instead. The panoramic camera shot of the lush green fields sets a peaceful tone. Although this is followed by the visual juxtaposition of a horse and carriage followed closely by a semi-trailer. The combined sounds of the horse trotting against the threatening hum of the semi-trailer are conflicting with the soft synthesizer music. This is the first indication that the world of the Amish and the modern world come into...

Eye Witness Testimony Can It Be Trusted?

...The age of the witness can affect the accuracy of recall, Valentine and Coxon (1997) studied this and it showed that the age of the witness can have an effect on the accuracy of eyewitness testimony. Anxiety can also affect focus. Psychologists tend to believe that small increases in anxiety and arousal may increase the accuracy of memory, but high levels have a negative effect on accuracy. In violent crimes (where anxiety and arousal are likely to be high), the witness may focus on central details (e.g. a weapon) and neglect other peripheral details. Loftus (1979) studied weapon focus in EWT. This is when the witness gets anxious and aroused, witnesses focus on a weapon at the expense of the other details, i.e. the criminals face. The cognitive interview. The cognitive interview was developed to increase accuracy. Cognitive psychologists have played a big part in helping to increase the accuracy of eyewitness testimony. As you’ve seen, research shows that the accuracy of eyewitness testimony is affected by many factors. The cognitive interview technique was developed by Geiselman et al (1984) to try to increase the accuracy of witnesses’ recall of events during police questioning. Here’s basically what happens in cognitive interviews: The interviewer tries to make the witness relaxed and tailors his/her language to suit the witness. The witness recreates the environmental and internal (e.g. mood) context of the crime scene. The witness reports......

Discuss the Effects of Age on Eye Witness Testimony

...effects of age on eye witness testimony Yarmey et al found little difference in accuracy of age-related recall but a difference in confidence of recall. He got a young woman to stop people in the street and chat to them for 15 seconds. She did this with 651 participants of varying age the youngest group was 18-29, the second group was 30-44 whilst the eldest group was aged 45-65. Two minutes later the participants were stopped again and asked to recall the physical characteristics of the woman. All age groups performed similarly but younger age groups were significantly more confident in their recall. Memon et al conducted an experiment with two age groups (16-33) and (60 to 82). When questioned 35 minutes after an event, age had little effect on accuracy of recall, however, a week later the older age group had declined significantly in their accuracy. This is because an elderly person has a deteriorated memory therefore suggesting that when interviewing elderly people after a certain period of time the information is distorted. Parker and Carranza et al created a study to study this as well, this study aimed to compare primary and college students ability to correctly identify a certain individual after a sequence of a mock crime. In the photo identification test, children had the highest rate of choosing the photos however, they were most likely to make mistakes of identification than college students. This shows that children are not the most accurate eye......

Lab Report

...2014 General biology lab Section: 13 T Instructor: Tasneem Obaid Introduction: Microscopes are instruments used to enlarge objects that are too small to be seen by one’s eyes. Microscopy is the science of the examination of small objects using microscopes. Technically we have two types of microscopes, the optical microscope which was first invented in late 1500s. It uses light and glass lenses (objectives) to magnify the image of an object up to 4X, 10X, 40X and a 100X. The second type is the electron microscope which was developed at early 1900s, it uses an electron beam in the place of light and electromagnets in the place of objectives to allow a much higher resolution up to two million times. In this experiment we will be using the optical microscope and not the electron microscope to examine specimens, as it is available in almost all the laboratories. In addition, the costs of the optical microscope is too low compared to that of the electron microscope. Moreover, the optical microscope can be stored in normal room temperature and pressure not requiring a vacuum as the electron one does. Materials: Compound light microscope and stereomicroscope. Prepared dry mount of the letter “e” . A plug. Method: First of all, we used a compound light microscope to assess the letter “e”. We followed the following procedure; A slide of dry mount of letter “e” was previously prepared. The letter was first observed by the naked eye and a sketch of......

Lab 8 Discussion

...Experiment 8 Lab Report Analysis of Oxidizing Capacity of Bleach The goal of this lab is to perform a titration of a sample of bleach with thiosulfate, figuring the end point with a starch indicator. We will determine the percent mass of sodium hypochlorite in bleach by using the volume of sodium thiosulfate needed to reach the end point. This value represents the oxidizing capacity of the unknown bleach. At the end, we will create two redox reactions to determine the overall chemical reaction that occurs during this process. I think that my oxidizing capacity will be 5.0g. Most bleach contains salts with the hypochlorite ion, the oxidizing agent that removes stains and whitens them. The hypochlorite ion usually comes in the form of sodium hypochlorite, NaOCl, or calcium hypochlorite. The two oxidation reduction reactions that occur during this experiment are first the oxidation of iodide to iodine, I2(aq), by the hypochlorite ion and then making the aqueous iodine reduce back to iodide by titrating it with sodium thiosulfate. The overall stoichiometry of the reaction is one mole of hypochlorous acid, formed by placing the sodium hypochlorite into acidic solution, plus two moles of the thiosulfate ion plus hydrogen ions from the solution yielding one mole of chlorite anions, one mole of the tetrasulfur hexoxide anion and one mole of liquid water. We began the titration of aqueous iodine by adding .05M sodium thiosulfate until the brown colored solution began to turn a...

Optic Eyes Lab Physic

...Name: Thao Vo Title: The Optics of the Eye Section 202 Monday 4:30pm – 7:15pm Course Name: Physics 246 Lab Partner’s Name: Jennifer Darlington, Hyon Hodge Date: 11/12/2012 Instructor: Dr Vermuru Word Count: 1650 Aim: The aim of this experiment is to examine a scaled up model of the human eye to understand the image formed in the eye, the optics of accommodation, nearsightedness, and farsightedness. Introduction: The basic structure of the human eye consists of cornea, natural crystalline lens and retina, as shown in Figure 1, in which the lens of the eye does little of the bending of the light rays, most of the refraction is done at the front surface of the cornea and retina plays the role of the film in a camera. Figure 1: Diagram of a human eye Accommodation is the focusing adjustment in which the muscles in the eye change the shape of the crystalline lens to change its focal length. Figure 2: Accommodation by a normal eye a) Lens relaxed, focused at infinity b) Lens thickened, focused on a nearby object Nearsightedness refers to an eye that can focus only on nearby objects. Because the far point is not infinity but some shorter distance, distant objects are not seen clearly. This defect is usually caused by an eyeball that is too long and images of distance objects are focused in front of the retina. In order to correct this defect, a diverging lens should be used as it causes parallel rays to diverge which allowing the rays to be focused at......

False Eye Witness Testimony

...eyewitnesses are interviewed hours, days or even weeks after the event thus relying on gist trace and long-term episodic memory (Leding, 2012). Long-term episodic memories, being reconstructive in nature, results in an eyewitness reconstructing the event using original information, prior semantic knowledge and schema-consistent information derived from schemas during encoding (Leding, 2012; Straube, 2012). This results in a distorted ‘remembering’ of an event that might be, but is not necessarily a true representation of what occurred (Leding, 2012). Eyewitnesses also use post event information when reconstructing their memories (Leding, 2012; Johnson, 2001; Straube, 2012). This is because episodic detail such as the source of information fades over time leaving behind the information itself. This leads to source monitoring errors where people confuse original information of the event information from external sources (Johnson, 2001). Therefore, false memories occur because of the confusion between internal and external sources of information or between various external sources of information (Johnson, 2001). So an eyewitness can testify to the truth of a piece of information when in reality, that information could have been provided to eyewitness from an external source such as another witness or the media (Leding, 2012). Furthermore, misleading questioning can also contaminate or distort an eyewitness’s memory so as to create false memories (Loftus, 2003; Loftus et al.,......

Outline and Evaluate Research Into the Affect of Anxiety on the Accuracy of Eye Witness Testimony

...the Accuracy of Eye Witness Testimony (6+6) Eyewitness Testimony refers to witnesses who are asked to give testimonies in court or police interviews to particular crimes. Eyewitness Testimony consists of : the eyewitness encoding the information they have witnessed the very second it happened, making sure they are describing the order of the events and the people involved. It also consists of the witness retaining information for a period of time (this can be a very long time) and finally it consists of the witness retrieving the information whilst they are in court. Eyewitness Testimony does have real life applicability as many people through DNA and false witnesses are sent to prison for crimes they did not commit therefore it is important to fully understand EWT to avoid innocent people being wrongfully punished. Eye witness testimonies are affected by a number of factors, but the one that I am going to focus on is anxiety. Many different laboratory studies and some ‘real life’ studies have generally shown recall is less accurate in people who have witnessed particularly distressing or anxiety filled situations. The weapon focus effect was created by Loftus (1979), she asked participants to sit outside a laboratory where they thought they were waiting to participate in an experiment, but they were actually already in it. As they were 'waiting', they heard a discussion between two people inside the laboratory. In one group, participants heard a discussion about an......

Outline & Evaluate Research Into How Age Affects Eye Witness Testimony

...demonstration followed by listening to a story which contained information on the demonstration as well as extra added material. Once questioned about the demonstration, the results showed that the children tended to mix information between the story and demonstration. In a follow up, they were questioned as to where they got this information and children who were older tended to do better than the children who were younger. Poole et al concluded that younger children would make for poorer witnesses as they struggled with “source recognition”. Rhodes et al used individuals from 3 different age groups (18-25; 35-45 and 55-78). They were shown 24 photographs which was representative of the three different age groups and asked to rate them for attractiveness. After that they were shown 48 photographs, 24 of which had been previously seen and 24 that acted as ‘distractors’. The results found out that young and middle aged participants were significantly more accurate than their older participants however, all age groups were most accurate in identifying pictures from their own age group. These findings fits in with the “differential experience hypothesis” which suggests that we are more able to identify people of our own age or of similar ethnic group. Therefore, the lack of experience with other age groups would result in a greater own-age bias. Similarly, the perceptual learning hypothesis suggests that individuals differ in the amount if expertise they have acquired for......

How to Write Discussion (Bio Lab Report)

...The Discussion should be written after the Results section so that you have a good idea of what the experiment has demonstrated. The discussion section should definitely have a statement of your expected findings (Pechenik, 86). This should include your hypothesis and a brief statement about why these types of results are expected. There should also be a comparison of how your actual results related to your expected findings (Pechenik, 86). Here, you should state whether or not your results supported or didn't support your hypothesis. In addition, the degree to which the evidence supported your hypothesis should be stated. For example, were the results completely supportive, or were there variances? There should be an explanation of unexpected results (Pechenik, 86). When looking for possible explanations, consider the following: Was the equipment used adequate for the task? Was the experimental design valid? Were the working assumptions made correct? A common mistake that many writers make is to blame themselves for the unexpected results. Unless you actually made a mistake following the methods of the experiment, and could not go back and correct it, do not make up such errors to explain the variances you observe. Think about and analyze the methods and equipment you used. Could something different have been done to obtain better results? Another possibility to consider is if the experiment was conducted under factors that were considerably different from those......
