The first route is the central route: attitudes are changed by having the motivation and ability to be able to process complex information, and is heavily based on evidence and logic. The second route is the Peripheral route: Where the individual lacks the motivation and ability to process the information and instead uses heuristic, mental shortcuts, to decide on their belief (The Effects of Structural and Grammatical Variables on Persuasion: An Elaboration Likelihood Model Perspective, pg. 350). Depending on the type of trial, it is important to keep the ELM model in mind for trial …show more content…

In communication studies, power is defined as the ability to influence others (Leadership: A communication perspective, pg. 136). Leadership is impossible without power; therefore it is important to choose an expert witness that carries a lot of power with them.
There are five main types of power used, but the focus should be a leader who can use legitimate power (positional power), expert power which is based on credibility and credentials, and/or referent power, or someone who is admired by many others and depends on feelings of affection, esteem, and respect (Leadership: A communication perspective, pg. 141). When a expert witness is challenged during the cross-examination, the opposing attorney will more than likely ask questions to make the expert seem less

E/M codes tell what was done in the office. Everything that the doctor or physician has done is documented, and coded. If a certain thing was not done then it should not be coded, and charged for that is considered fraud. Also everything that is done in the office must be documented, and coded using the E/M codes. If the E/M coding was done incorrectly the person would get in trouble for fraud, and not only that the office would have a bad reputation, and other insurance companies wouldn 't probably want to go through that office anymore.

v Lavallee (1990), expert testimony is admissible if the evidence is relevant to the case, even if it is based on hearsay. Though the appellant did not testify, rule 804 of the Federal Rules of Evidence allows hearsay statements to be considered in the event that the appellant refuses to testify (Matson, 2004). The hearsay evidence assists the expert in determining their opinion, but it is not used as evidence to the existence of the facts. As long as there is some admissible evidence to the expert’s testimony, the jury or judge cannot ignore it – the greater matter is determining how much weight should be given to the testimony. The judge is required to warn the jury of the reliability and credibility of the information, and to determine a weight at which the jury should use to influence their decision regarding the case (Ottawa L. Rev.,

The assessment of an affirmed expert capability in his or her field is not a novel idea, and it is well inside of the capacities of our skilled federal judiciary. Once a judge has chosen a witness is qualified to serve as a specialist, Daubert requires the judge to make an autonomous appraisal to "guarantee that any experimental confirmation or proof conceded is important, as well as solid. This includes an examination of the philosophy fundamental the expert assessment to figure out if it uses legitimate experimental techniques and strategies.
