Neon lights advertisements are seen everywhere in Hong Kong. How they distract car drivers?
Part 1:
Broadbent, filter model, selective attention
Broadbent theory supports that a filter is located in between the incoming sensory register (eyes, nerve impulses), and the short-term memory storage in our brain, with attention that not all information make it to the third stage (long term memory) or other stages as the filter works together with a buffer. The stimuli presented at the same time are held in the short-term sensory buffer, and its information can be retained there for a short period before being processed. After that it disappears from the processing system, which means that the same filter makes an analysis regarding semantic content (meaning within conscious awareness) and selects one of the inputs on the basis of its physical characteristics, passing it through a limited capacity channel for further processing. Any stimuli not selected by the filter doesn’t receive this semantic analysis and never reaches conscious awareness, although occasionally could be stored in the unconscious.
Neon lights from outdoor advertising in Hong Kong could be well managed if the driver can balance correctly the outcome of colours and signs present in the ads, at the same time he focus on sensory aspects that come with the act of driving and traffic conditions at the moment.
Taking in account Broadbent’s filter theory, a filter do exists and functions like a sort of protecting barrier, absorbing conditions, processes, handling both stimulus at the same time, but dividing them appropriately and assigning one out of other choices to immediately process or hold for later processing.
This means that the filter prevents overloading of messages and therefore the overloading of the tremendous advertising sensory aspects we can experience in a flashy billboard crowded street in Hong Kong. Hence, ultimately the attention-to-memory processing will lead to a single focus and processing of complex information about the driving conditions, managing well the challenge of cruising the streets of Hong Kong.
However, if the filter chooses to direct attention to the neon flashy outdoor advertisements, all the drivers which had it more inclined to ‘choose’ processing information such as the neon lights would put the individual in a serious problem when driving. One could imagine processing an ad message without paying attention to the traffic (although it might happen in some situations, namely when text messaging, it is not the average).
Thus, in this situation the attention and information processing were driven out to secondary aspects instead of the primary aspect that is the current action of driving, makes this theory ambiguous to the case as people can drive in harsh conditions and in the streets of crowded ad spaces such as Hong Kong. Therefore, probably not applicable to the case in terms of cognition related to visuals, but others would be applicable such as Broadbent’s auditory experiences.
More, the outcome we can take from here regarding advertising effectiveness is that within a crowded ad space, people tend not to pay attention to specific advertising unless it is remarkable. The cognitive process described above, although not fully fitting the overall ad space context, we can argue that a person in principle doesn’t process / store information about probably more than half ads present in a crowded space such as Hong Kong streets outdoor advertising.
