Answer:
An operational definition is the preise meaning of a term used to describe a variable such as a type of behavior, which researchers want to measure.
Explanation:
Every variable used in a research must have two definitions: the conceptual definition and the operational definition. The conceptual definition is the one that can be found in a dictionary, it explains the construct and its relationship to other constructs. The operational definition defines de variable in terms of observable constructs that can be measured empirically. For example, when studying different types of behavior, the operational definition must make clear what empirical elements define each type of behavior.
Answer:
spontaneous recovery
Explanation:
Responses to a stimulus are conditioned into individuals and some of them may remain dormant or in rest.
When such responses are reactivated it is called spontaneous recovery.
In the given scenario Tina had an accident and subsequent panic attacks every time time she came to the parking lot.
After sometime the panic attacks stopped only for them to come back again unexpectedly.
This is an example of spontaneous recovery after a dormancy period.
Answer: It allowed him to navigate the seas using the sun and stars.
Explanation: The astrolabe enables astronomers and sailors to calculate the position of the Sun and stars with respect to the horizon and the meridian. The astrolabe can calculate the altitude and predict the position of celestial objects in time. An astrolabe is a device that uses astral bodies like the sun and stars to either tell your position in latitude or tell the local time. It can also be used to measure celestial events like the wobble of the Earth's axis. An astrolabe can tell your position in latitude or tell the local time.
