Major Research Report for Social Psychology

To analyze the effects of confidence and post-identification feedback on belief of eyewitness evidence

The focus of the current project report is analyzed the impact of confidence and post identification feedback on belief of eyewitness evidence. This project report emphasises on eyewitness identification error which is associated with 75% of DNA exoneration. This reports are all about conducting an experiment that facilitates an individual in order to collect important information in concluding the report within a given period. The focus of this project report is to clarify al the principles of investigative process conducted police in comparison with various legal process to be followed by police officers in order to collect all evidences from the suspected individual.

Police verification process also play an important role in identifying all the suspects by emphasises on different hints collected by an individual.

Effects of investigation process of identification of evidences or interrogating eyewitnesses is the basis research problems whose efficiency will be assessed in the overall research project (Wells, 2016). The researcher will emphasis in the higher expectations and needs of an individual in order to grab higher opportunity of resolving the case as early as possible to save the time of legal officials. The resolving all he cases play an important by providing justice to the aggrieved party to the case is important process which involves deeply evaluation of all the matters included in the case as the police verification play an important role in communicating important investigation with the higher authority as they will take important decisions based on the collected facts. The current research study will focus on four important criterion's that acts like an important pillars in defining the overall research in the right direction to facilitate the research who will accomplish all the tasks associated with the given research report.

The research methods are selected by an individual according to the overall nature of the report as varied nature of the research report will facilitate the researcher in order to select the best appropriate method of the research in accomplishing all desired goals and the objectives of a particular report framed by an individual.

The selection of quantitative methods will help the researcher in order to test the statistical accuracy of the collected data used for the purpose of overall analysis as their desired aim is to apply statistical tools in accomplish all the desired aims and the objectives within a given period (Horry and Brewer, 2016). In the current psychological research study experimental research method will be used by an individual in order to observe the overall process in order to identify the final outcomes which helps an individual in order to collect important evidences for the beneficial of the researcher. In the experimental research the outcomes will be observed by the researcher which increase the overall reliability of the data collected by the researcher for resolving the desired aim of the research as the results of the current research study will help in amending the existing processes of identification in order to improve the overall legal systems in which real process are followed in order to accomplish desired aims and the objectives in a particular period.
