PSY342H1 Chapter Notes - Chapter 3: Attentional Blink, Stimulus Modality, Change Blindness
Document Summary
Chapter 3: attention: attention is the process that enhances some information and inhibits other information. The enhancement enables us to select some information for further processing and inhibition allows us to set some information aside: attention has three components; orienting to sensory events, detecting signals for focused processing and maintaining an alert state. Failures of selection: when there is a lot of information simultaneously present in front of us, we fail to notice all the information all at once. When the available capacity is less than required for completion of a task, failures are frequent. The phenomenon of attentional blind also occurs for two objects that are presented in rapid succession. The second event is just assimilated into the first one. The effect of response bottleneck has been observed in driving where drivers try to use cellphone and drive at the same time which creates a problem and leads to accidents.
