Default Reaction

A

We go on autopilot but we are able to override

47
Q

Bottom-up processing

A

starts at your sensory receptors and works up to higher levels of processing. (boiling pot example)

48
Q

Top down processing

A

constructs perceptions from this sensory input by drawing on your experience and expectations (Meeting someone after rumors)
