Vaselesa [24]
The correct answers are: <span>extinction; spontaneous recovery

Answer 1: 
T</span><span>eresa's change in behavior can probably best be explained in terms of extinction. 

According to the theory of classical conditioning, extinction refers to the process whereby </span>a previously learned behavior disappears when reinforcement stops occurring. In this instance, Teresa was previously anxious about dentist visits due to the pain she experienced. However, when her mother took her to a new dentist who took care to make her visits painless, Teresa gradually <span>becomes less resistant about going to the new dentist. This demonstrates the process of extinction, because Teresa's  previously learned fear of visiting the dentist gradually disappeared when reinforcement of the fear stopped occurring. 

Answer 2: The correct answer is </span>spontaneous recovery.

According to the theory of classical conditioning, spontaneous recovery (SR) refers to the reappearance of a conditioned or learned response after a period of time has elapsed. In other words, SR refers to when <span>an extinct behavior suddenly reemerges. In this instance, Teresa's conditioned fear response became extinct after she visited the second dentist, however, after a period of three years where she didn't visit a dentist, her fear of the dentist reemerged, thus demonstrating the process of SR. </span>

What 3 things do people want to protect when they form a government
Gnom [1K]

Protect and provide

The concept of government as provider comes next: government as provider of goods and services that individuals cannot provide individually for themselves. Government in this conception is the solution to collective action problems, the medium through which citizens create public goods that benefit everyone, but that are also subject to free-rider problems without some collective compulsion.

The basic economic infrastructure of human connectivity falls into this category: the means of physical travel, such as roads, bridges and ports of all kinds, and increasingly the means of virtual travel, such as broadband. All of this infrastructure can be, and typically initially is, provided by private entrepreneurs who see an opportunity to build a road, say, and charge users a toll, but the capital necessary is so great and the public benefit so obvious that ultimately the government takes over.

A more expansive concept of government as provider is the social welfare state: government can cushion the inability of citizens to provide for themselves, particularly in the vulnerable conditions of youth, old age, sickness, disability and unemployment due to economic forces beyond their control. As the welfare state has evolved, its critics have come to see it more as a protector from the harsh results of capitalism, or perhaps as a means of protecting the wealthy from the political rage of the dispossessed. At its best, however, it is providing an infrastructure of care to enable citizens to flourish socially and economically in the same way that an infrastructure of competition does. It provides a social security that enables citizens to create their own economic security.

The future of government builds on these foundations of protecting and providing. Government will continue to protect citizens from violence and from the worst vicissitudes of life. Government will continue to provide public goods, at a level necessary to ensure a globally competitive economy and a well-functioning society. But wherever possible, government should invest in citizen capabilities to enable them to provide for themselves in rapidly and continually changing circumstances.

Not surprisingly, this vision of government as investor comes from a deeply entrepreneurial culture. Technology reporter Gregory Ferenstein has polled leading silicon Valley entrepreneurs and concludedthat they “want the government to be an investor in citizens, rather than as a protector from capitalism. They want the government to heavily fund education, encourage more active citizenship, pursue binding international trade alliances and open borders to all immigrants.” In the words of Alphabet Chairman Eric Schmidt: “The combination of innovation, empowerment and creativity will be our solution.”

This celebration of human capacity is a welcome antidote to widespread pessimism about the capacity of government to meet current national and global economic, security, demographic and environmental challenges. Put into practice, however, government as investor will mean more than simply funding schools and opening borders. If government is to assume that in the main citizens can solve themselves more efficiently and effectively than government can provide for them, it will have to invest not only in the cultivation of citizen capabilities, but also in the provision of the resources and infrastructure to allow citizens to succeed at scale
