What is meant by relevance reliability

Saul McLeodpublished The term reliability in psychological research refers to the consistency of a research study or measuring test. For example, if a person weighs themselves during the course of a day they would expect to see a similar reading.

The side that calls the witness first asks questions in what is called direct examination. The opposing side then may ask their own questions in what is called cross-examination. In some cases, redirect examination may be used by the side that called the witness but usually only to contradict specific testimony from the cross-examination.

Recalling a witness means calling a witness, who has already given testimony in a proceeding, to give further testimony. A court may give leave to a party to recall a witness only to give evidence about a matter adduced by another party if the second party's testimony contradicts evidence given by the original witness on direct examination.

Testimony[ edit ] Witnesses are usually permitted to testify only what they experienced first-hand. In most cases, they may not testify about something they were told hearsay. That restriction does not apply to expert witnesses, but they may testify only in the area of their expertise. Reliability[ edit ] Eyewitness testimony is generally presumed to be more reliable than circumstantial evidence.

Studies have shown, however, that individual, separate witness testimony is often flawed, and parts of it can be meaningless. That can occur because of flaws in eyewitness identification such as faulty observation and recollection, or bias or because a witness is lying.

If several people witness a crime, it is probative to look for similarities in their collective descriptions to substantiate the facts of an event but to keep in mind the contrasts between individual descriptions.

One study involved an experiment, in which subjects acted as jurors in a criminal case. Jurors heard a description of a robbery-murder, a prosecution argument, and then an argument for the defense.

Some jurors heard only circumstantial evidence ; others heard from a clerk who claimed to identify the defendant. In another study, students watched a staged crime.

An hour later they looked through photos. A week later they were asked to pick the suspect out of lineups.

Another study looked at 65 cases of "erroneous criminal convictions of innocent people. That is done by employing the mental skills at one's disposal like thinking, perception, memory, awareness, reasoning, and judgment. Although cognitive processes can be only inferred and cannot be seen directly, they all have very important practical implications within a legal context.

If one were to accept that the way people think, perceive, reason, and judge is not always perfect, it becomes easier to understand why cognitive processes and the factors influencing the processes are studied by psychologists in matters of law, one being the grave implications that this imperfection can have within the criminal justice system.

The study of witness memory has dominated the realm of investigation. As Huff and Rattner [2] note, the single most important factor contributing to wrongful conviction is eyewitness misidentification. Credible witness Several factors affect witnesses' credibility. Generally, they are deemed to be credible if they are recognized or can be recognized as a source of reliable information about someone, an event, or a phenomenon.

As an example, the arrest of an illegal immigrant from El Salvador in the murder of federal intern Chandra Levy saw many questions arise surrounding the credibility of various witnesses. Contesting the credibility of so-called "expert" witnesses rose into more common practice in the s and s.Products Over Projects.
