<P> These decisions may be greatly influenced by these external forces and alter the way individuals view an object . For example, research has shown that people rank television commercials as either good or bad in relation to their enjoyment levels of the show during which the commercials are presented . The more they like or dislike the show the more likely they are to rate the commercials shown during the show more positively or negatively (respectively). Another example shows during sound recognition a context effect can use other sounds in the environment to change the way we categorize a sound . </P> <P> Context effects can come in several forms, including configural superiority effect which demonstrates varying degrees of spatial recognition depending on if stimuli are present in an organized configuration or present in isolation . For example, one may recognize a fully composed object faster than its individual parts (object - superiority effect). </P> <P> Context effects can have a wide range of impacts in daily life . In reading difficult handwriting context effects are used to determine what letters make up a word . This helps us analyze potentially ambiguous messages and decipher them correctly . It can also affect our perception of unknown sounds based on the noise in the environment . For example, we may fill in a word we cannot make out in a sentence based on the other words we could understand . Context can prime our attitudes and beliefs about certain topics based on current environmental factors and our previous experiences with them . </P> <P> Context effects can be nullified if we are made consciously aware of the outside stimulus or past history that may influence our decision . For example, a study conducted by Norbert Schwarz and Gerald Clore showed that when asked to rate their overall life satisfaction on either sunny or rainy days, people expressed greater satisfaction on sunny days and less satisfaction on rainy days . However, when people were reminded of the weather their satisfaction rating returned to an almost even distribution . This study demonstrates the effect the environment can have on perception, and that when pointed out, context effects can be nullified . </P>
