In summary, sensation first allows us to pick up the signals in our environments, and perception then allows us to assemble these signals into something meaningful. After that, our response declines in strength: ex. When we sit on a chair after a few seconds, we no longer notice it. Sensory systems do not stick to one sense. Attention: flexible attention is critical to our survival and well-being, selective attention: allows us to select one channel and turn off the others, or at least turn down their volume, ex #1. Filter theory of attention views attention as a bottleneck through which information passes. This mental filter enables us to pay attention to important stimuli and ignore others: ex #2. Dichotic listening in which participants hear two different messages, one delivered to the left ear and one to the right ear: ex #3.
