At
any given moment we are being bombarded by physical and psychological stimuli
competing for our attention. Althrough our eyes are capable of handling more
than 5 million bits of data per second, our brains are capable of interpreting
only 500 bits of data per second. With similar disparities between each of the
other senses and the brain, it is easy to see that we select the visual,
auditory, or tactile stimuli that we wish to compute at any specific time.
Question:
(1)Physical stimuli usually win in
the competition for our attention.

is sufficient to interpret nearly all the stimuli the senses can register under
optimum conditions.

Most
banks and buliding societies adopt a “no smoking” policy in customer areas in
their branchs. Plaques and stickers are displayed in these areas to draw

being infringed. If a customer does ignore a notice, staff are tolerant and
avoid making a great issue of the situation. If fact, the majority of customers
