Helmsley – stored memory gets confused with new incoming information. Therefore, they cannot use schemas to make sense of their situation meaning that they are subjected to an overload of sensory information and do not know which to attend to. He also suggests that the internal voice is not recognised.
Bental – Suggests that sz have attentional bias towards stimuli that are life threatening and have an emotional nature and therefore these thoughts are given priority.

Bellson – agree with desensitisation theory

Violence is more likely to frighten children.
The theory can only account for desensitising for screen watching rather than real life violence.

2. Comprehension - The message must be easy to understand. This is less important in advertising as many television adverts intentionally encourage peripheral route.
3. Favourable association –
