<u>Using stone to build tools.</u>
Stone was a familiar material that was used in numerous ways.
The wheel, plow, and writing (a system which we call cuneiform) are examples of their achievements. The farmers in Sumer created levees to hold back the floods from their fields and cut canals to channel river water to the fields. The use of levees and canals is called irrigation, another Sumerian invention.
Answer:
True
Explanation:
It is true that shaping is often used in operant conditioning in order to learn complex behaviours. Shaping occurs when, instead of only rewarding the target behaviour, approximations of the behaviour are also rewarded. This is due to the expectation that over time, these behaviours would grow closer to the desired response. Therefore, the behaviour is considered to be gradually changed, or "shaped."
Answer:Stage of psychosocial development that Lesley is in according to Erik Erikson is referred to as EGO INTEGRITY VS. DESPAIR
Explanation:
Erik Erikson suggests that as we move through different stages of life we experience particular psychological conflict. Through these conflicts we can either conclude positively or negatively.
When people are in their late adulthood their conflict is Ego intergrity versus Despair when someone reflect on their lives in terms of what they have done and achieved or not achieved .
Like Lesley almost everyone at their old age will reflect back on their accomplishments and either be content or be regretfully and unsatisfied
Lesley is proud and content with all her accomplishments in life , she is proud of the choices she made, careers she chose and the family she raised , she has established her Ego integrity since she feels complete.
However if Lesley was not content and regretted the choices that she had made and felt like there was no time left to make up for all those things she couldn't do right and what she has failed to accomplish that will put her on despair
