Stress can result from either negative or positive situations.<br><br> a. true <br> b. false
marta [7]

a) true

Stress has mostly been perceived as a negative emotion and one that should be avoided in the interest of good mental and physiological health. But the pioneering work of renowned psychologist Dr. Richard Lazarus has proven this perception to be flawed.

Dr. Lazarus argued for a distinction between eustress, which refers to positive stress, and distress, which implies negative stress.

Eustress occurs in the presence of positive stressors such as acing an exam and getting a promotion. Eustress causes one to feel motivated and improves performance. Distress is caused by negative situations like death of a love one or illnesses, and causes anxiety and depression.

Although Mr. Wright often tells his children about the importance of donating time and money to charitable causes, he rarely doe
den301095 [7]

Answer:

1. Students should explain that observational learning theory predicts that Mr. Wright's children will imitate both his actions and his excuses. Observational learning studies indicate that observational learning will occur most powerfully when the actions and words of models are consistent; when models do one thing and say another, children will do what they see adults do and say what they hear adults say. Students should advise Mr. Wright to provide an effective model to his children by actually donating time and money to charity and continuing by talk about why this is important. This model is more likely to increase the chances of his children learning this behavior through observational learning.

2. UCS- alcohol

UCR- sense of well-being

CS- smell of alcohol

CR- sense of well-being

-alcohol (UCS) causes the UCR; UCS naturally and automatically cause (UCR) a sense of well-being, without any previous conditioning

-since the smell of alcohol is paired repeatedly with actual alcohol (UCS), it is likely to eventually elicit the UCR (sense of well-being)

—sense of well-being is the UCR to the UCS of alcohol, the smell of alcohol (CS) is likely to eventually elicit the CR of a sense of well-being

-the presentation of the CS (smell of alcohol) without the UCS (alcohol), with repeated pairings, will eliminate the conditioned response (CR). Therefore, extinction has taken place.

3. OC: stimulus (S) —> response (R) —> reinforcement (R1)

-some psychoactive drugs produce a tolerance effect. Drug users need to take increasing doses of the drug to achieve the same physiological effect. Tolerance leads to withdrawal symptoms.

-any drug that produces tolerance leads to withdrawal symptoms. Drug users experience extremely negative symptoms when they are without the drug (strokes, night sweats)

-drug addicts might use psychiatric drugs to alleviate withdrawal symptoms. Negative reinforcement occurs when a behavior is followed by the removal of an aversive stimulus (elimination/reduction of withdrawal symptoms when an addict uses a drug again). This negative reinforcement increases the likelihood that the drug addict will use the drug again.

Suppose there are five families in a country and their income is 15 lakhs, 20 lakhs , 12 lakhs, 8 lakhs and 25 lakhs respectivel
Rainbow [258]

Answer:

16 lakhs per family

Explanation:

Per capita income is the mean income of the people in an economic unit. An economic unit may be a city or country. It is calculated by taking the sum of all sources of income and dividing it by the total population.

There are five families in a country and their income is 15 lakhs, 20 lakhs , 12 lakhs, 8 lakhs and 25 lakhs.

First, let's take the sum of the income.

Sum=15+20+12+8+25=80

Average=80÷5=16

The per capita income of the country is 16 lakhs per family.

Note that:

1 lakh=100,000
