divided attention (multitasking)

It is easier to perform two tasks at the same time if the tasks are:

Dissimilar, less, difficult, Well-practiced

Occurs when an organism changes its pattern of behavioral responding to repeated presentations of a stimulus over time (one of the simplest forms of learning)

Non-associative learning

Repeated exposure to a stimulus can result in a decrease in behavioral response over time

habituation

Occurs when there is a renewed (increased) response to a previously habituated stimulus (renewed response)

dishabituation

When repeated exposure to a stimulus produces an increase in a behavioral response over time

Sensitization

Occurs when the behavioral response to a previously sensitized stimulus decreases over time

desensitization
