Reports also show that the magnitude of improvement via context reinstatement increased in lifelike situations compared to laboratory studies. Verbal overshadowing effect[ edit ] The process of describing a face entails thinking about its features independently, but people process faces configurally as a whole, encoding the features in relation to one another.

However, recent data suggests the preference for sequential lineups over simultaneous lineups may not be empirically supported. However, researchers such as Dr. Witnesses who believe that they are able to retrieve an accurate mental photograph will also be much more confident in their account of the event and may influence the trial outcome.

One study has found that recall is enhanced when both auditory information is heard and visual information is seen, as opposed to just hearing auditory information. Gary Wells from Iowa State University claim "during simultaneous lineups, witnesses use relative judgment, meaning that they compare lineup photographs or members to each other, rather than to their memory of the offender.

In a simultaneous lineup, the photos or suspects are viewed together. The photographs were presented simultaneously, allowing Jennifer to compare the photographs to each other as opposed to her memory of the event. Similarly, upon hearing a low-pitched voice, they are likely to remember the voice as being even lower in pitch when voices are presented in an audio line-up.

As a result, when she was later asked to choose her assailant from a physical line-up, Jennifer saw Ronald in her memory and thus chose him.
