Eye Witness Testimony and Evidence (Research Paper Sample)


Lab 6.3 Research Report: Be A Juror
The aim of this assignment is to prepare you for your final research report. Below you will see some background on the proposed study you will be analyzing and writing up as a research report. For this assignment, I have designed the study for you, provided you with the data you need to analyze, and proposed your data analysis that you will conduct. You will be working in your previously created groups.
Study Background
Eyewitness testimony research has informed the federal government's guidelines for competent use of eyewitness evidence in criminal matters (Wells, Malpass, Lindsay, Fisher, Turtle, &Fulero, 2000). Such research has led the New Jersey Supreme Court to mandate that judges tell jurors that eyewitness memory can be unreliable (Weiser, 2012). An important question is how juries actually respond to evidence and to cautions about the strength of the evidence.
Not surprisingly, the question is complex because of the wide variety of factors that can affect juries (Devine, Krouse, Cavanaugh, &Basora, 2016; Wells & Olson, 2003). However, psychological scientists have identified some strategies that might help jurors reach optimal decisions (Rodriguez & Berry, 2016).
The Proposed Study
The computer randomly assigns each participant to one of three different scenarios, in which the participant learns details of a crime. In the first scenario, the defendant provides testimony and argues he is not guilty. The second scenario is similar but also includes a statement that a witness saw the defendant commit the crime. In the third and final scenario, an attorney indicates that the witness was not wearing his glasses, thus his testimony may have been false. Loftus (1979) found that participants, acting in the role of juror would be more likely to convict someone on the basis of eyewitness testimony, even if that testimony were questioned.
Proposed Design
Participants are in one of three treatment conditions (a) no eyewitness, (b) unrefuted eyewitness, and (c) discredited eyewitness. Participants in this study rate their belief about the defendant's guilt. The rating scale ranges from a 1 (definitely not guilty) to a 7 (definitely guilty)
Data Analysis
The analysis that will conducted with this study is a one-way ANOVA that explores whether there is a difference between the treatment conditions. Post-hoc analyses can illustrate which means differ ( if needed). SPSS must be used to analyze the data. Please use this6.3 data attach pdf file

Eye Witness Research
Witnesses also play a key role in revealing the facts of a crime. They will be vital to locate, prosecute and potentially convict convicted criminals. Therefore, it is important for the accuracy and reliability of the testimony of eyewitnesses. The most precise and credible information obtained by our eyes as inspectors is to observe sound procedures through our inquiries.
Recent cases where DNA proof was used to exonerate people convicted mainly on account of evidence from eyewitnesses showed us that data from eyewitnesses cannot be infelized. That is also the essence of human memory because most truthful and objective individuals may make errors to remember and understand an occurrence they have experienced. In the last decade, this problem became at the center of an increasing number of studies on the identity of eyewitnesses. In collaboration with these scholars, the National Institute of Justice has assembled a committee of scientific working parties on the compilation and preservation of eyewitness proofs in the criminal justice system.
Literature review
The eyewitness evidence investigation told the guidance of the federal government on professional use of eyewitness evidence in crime issues (Wells, Malpass, Lindsay, Fisher, Turtle, &Fulero, 2000). The New Jersey Supreme Tribunal was ordered by those studies to tell jurors that the recollection of eyewitnesses can be inaccurate (Weiser, 2012). An significant question is how juries react to proof and warnings about the strength of the proof.
Not unexpectedly, because of the many variables that may influence jurors the issue is difficult
