Homework Assignment #2 Developmental Psychology During this unit, some of the class examples include language development and how children acquire and use language to communicate needs and wants. In this assignment, you will learn to apply test calculation skills in a different context, moral development in children. By morality, we are referring to the idea of what is right and what is wrong, fair and unfair, just and unjust. Research on moral development in psychology generally falls into two categories: moral conduct (exhibiting behaviors that demonstrate moral development) and moral reasoning (the ability to understand and know about morality). For example, a researcher who measures how often Sandy steals candy from her desk when she is out of the room, when the child has specifically been told not to do this, is measuring a behavior associated with morality.

On the other hand, a researcher who tells another child about this stealing episode and asks, “What do you think about what Sandy did?†is investigating moral understanding without asking the child to actually do something that is moral/immoral. Let us consider the following research scenario where researchers are interested in the moral development of children at two different ages: 5 and 7 (major cognitive shifts may happen around these ages). These researchers are using Turiel’s model of moral reasoning to assess the children. Turiel proposes that moral reasoning is comprised of different domains in which the child applies what they know about right and wrong. Two of the most important domains are the moral domain and the societal domain: the moral domain deals with peoples’ rights, fairness and justice, while the social domain has more to do with politeness and relationships.

Until the mid-1970’s children’s moral reasoning was assessed using adult measures, and it is hardly surprising that researchers found that children did not appear to display moral reasoning until adolescence. Turiel used his model to develop a method of interviewing and testing children in language and activities that were understandable to young children, and found that he could show their ability to understand these concepts at a young age. Our researchers are interested learning more about when children develop understanding in the moral domain. They recruited two samples of 16 children: one sample of five-year-olds another of seven-year-olds. All children in both samples answered questions to see how quickly they could distinguish between moral and societal transgressions and explain their answer satisfactorily (in minutes).

The time it took for each child can be found in the table below.

Homework Assignment #2 Developmental Psychology Heckel 1 Annie Heckel Professor Harper LITR September 2014 Love Over All: Love’s Triumph Over Dharma in The Sakuntala In Hindu culture and belief, the idea of “dharma†or duty is an important concept that shapes the life of individuals on many levels. When viewed through the lens of an individual’s caste, it dictates what sorts of work that individual can do, as well as how the person must respond to others of higher or lower castes, something we see in The Sakuntala in the scene with the fisherman.

In the individual’s personal life, dharma can require a person to respond in certain ways to family members or other members of society, as shown in the section of The Ramayana where King Dasaratha must grant Queen Kaikeyi’s request that he exile his beloved son Rama even though the exile is unfair and against Dasaratha’s wishes. When considering The Sakuntala and The Ramayana together, however, there are significant differences in the role that dharma plays in the story. Duty in the Sakuntala is more of backdrop in the setting of the story, an assumed quantity, and only when it is violated does it really become noticeable. Rather than the emphasis being on dharma, as it is in The Ramayana , the main focus of The Sakuntala is on love, and dharma’s influence is secondary to the power of love.

Early on in The Sakuntala , we do see dharma featured as a way to establish the main characters as upright and good people. Dushyanta's acquiescence to the hermits' requests, and deference to the hermits is an example of this (Kalidasa ). Dushyanta’s honorable response to the hermits, who as priests are of a higher social status than Dushyanta, can be seen Heckel 2 as a manifestation of dharma because it shows Dushyanta knows and respects his place in the caste system. This knowledge and respect of the caste system is also shown in Dushyanta’s wish that Sakuntala might be “sprung from a caste different from that of the Head of the hermitage†(Kalidasa 384); cross-caste marriages are not considered appropriate, and Dushyanta hopes that dharma will not prevent their union.

He knows that if Sakuntala is of the same caste as Kanwa, the head of the hermitage, then Dushyanta, being of a different caste, cannot marry Sakuntala without violating social restrictions, something he is not willing to do. Another manifestation of dharma in The Sakuntala is shown through the importance of Sakuntala’s proper observance of the rites of hospitality. Correct adherence to rites of hospitality is shown on p. 386, when Sakuntala and her attendants are careful to offer Dushyanta the appropriate greetings and actions of welcome. However, later on in the play, it is these same rites that become the main cause of conflict when they are not observed.

Sakuntala is daydreaming of Dushyanta, and therefore the duty of respectful greeting owed to Durvasas is neglected, causing Durvasas to utter the curse that makes Dushyanta forget Sakuntala: He, even he of whom thou thinkest, he Shall think no more of thee; nor in his heart Retain thine image. Vainly shalt thou strive To waken his remembrance of the past; He shall disown thee, even as the sot, Roused from his midnight drunkenness, denies The words he uttered in his revellings. (Kalidasa 415) Durvasas’ curse here specifically focuses on the object of Sakuntala’s daydream—it is an “eye for an eye†kind of punishment that could be considered “instant karma†for her neglect of duty. Heckel 3 Love has caused duty to be forgotten, so in order to enforce the importance of duty, love must be forgotten in turn.

This “eye for an eye†curse for violating dharma might seem to indicate that duty is considered more important than love since at this point in the play, neglect of duty causes love to be lost. Love, however, and the romantic relationship between Dushyanta and Sakuntala, triumph in the end; duty becomes just an agent used to add the conflict that drives the plot. In the conflict between love and duty, love ends up winning out; Durvasas, being somewhat mollified by Priyamvada, is willing to provide a way for his curse to be broken, even though Sakuntala never actually rouses herself to greet him or beg forgiveness. In the Ramayana, by contrast, duty seems to be a much stronger theme; it is duty, not love, that drives the characters themselves the most, and duty will even interfere with the motivations driven by love, as is the case with Dasaratha's constraint by duty to Queen Kaikeyi when he is forced to exile his beloved son Rama.

If duty were not paramount, Dasaratha would not give in to what he knows to be Kaikeyi’s jealousy—his love and respect for Rama would instead win. However, because Dasaratha has made an oath to grant Kaikeyi’s request, he is forced by his duty to fulfill his word to do something repugnant to him and his love for his son. Similarly, the problems with Rama and Sita's relationships after each time she has been kidnapped show this issue of duty winning over love. Where in a love-focused story we might expect that “love conquerors all†and Rama would have faith that Sita was pure, we instead see that Sita must fulfill the demands of duty and prove her purity. By contrast, in Sakuntala, love is the primary motivation, driver of action, and ideal.

In the end, Sakuntala does not have to prove her purity; it is instead Dushyanta must prove his love, as we eavesdrop on his lamentations along with the nymph Sanumati in Act VI (Kalidasa ). Dushyanta’s lovesick behavior Heckel 4 and his subsequent obedience to the gods are what prove him worthy of recovering his lost wife and meeting his superhuman son. All in all, love is the focus in Sakuntala, and while dharma has a place, it is more as a backdrop than as a central theme. When reading The Sakuntala in conjunction with The Ramayana , where dharma is the main theme, it is very clear how small a role dharma and karma play in the story of Dushyanta and Sakuntala. Though duty drives the action of The Sakuntala and helps to show the audience what the characters are like, love is the main theme and the final triumphant force of the play.

Assignment 2: Calculating Mean, Standard Deviation, and Testing Hypotheses in the Context of Moral Development in Children

1) Calculate the Mean and Standard Deviation for the Sample of 7-Year-Olds

Given the time taken by children in the 7-year-old sample, we need to calculate the mean and standard deviation.
Assume the following times (in minutes) for each child in Sample #2 (A to P):
- A = 25
- B = 30
- C = 34
- D = 60
- E = 40
- F = 50
- G = 45
- H = 35
- I = 70
- J = 65
- K = 55
- L = 30
- M = 20
- N = 42
- O = 33
- P = 38
##### Mean Calculation:
Mean (M) is calculated using the formula:
\[
M = \frac{\sum\text{X}}{N}
\]
Where \(\sum\text{X}\) is the sum of all observations, and \(N\) is the number of observations.
Calculating the sum of these times:
\[
\sum\text{X} = 25 + 30 + 34 + 60 + 40 + 50 + 45 + 35 + 70 + 65 + 55 + 30 + 20 + 42 + 33 + 38 = 60 \times 12 = 540
\]
There are 16 children, thus:
\[
M = \frac{540}{16} = 33.75
\]
##### Standard Deviation Calculation:
The standard deviation (SD) is calculated using the formula:
\[
SD = \sqrt{\frac{\sum(X - M)^2}{N - 1}}
\]
Calculating variance first:
1. Calculate \((X - M)^2\) for each child:
- (25 - 33.75)² = 76.5625
- (30 - 33.75)² = 14.0625
- (34 - 33.75)² = 0.0625
- (60 - 33.75)² = 676.5625
- (40 - 33.75)² = 39.0625
- (50 - 33.75)² = 262.5625
- (45 - 33.75)² = 126.5625
- (35 - 33.75)² = 1.5625
- (70 - 33.75)² = 1306.5625
- (65 - 33.75)² = 992.5625
- (55 - 33.75)² = 441.5625
- (30 - 33.75)² = 14.0625
- (20 - 33.75)² = 187.5625
- (42 - 33.75)² = 67.5625
- (33 - 33.75)² = 0.5625
- (38 - 33.75)² = 18.0625
2. Sum of squared differences:
\[
\sum(X - M)^2 = 76.5625 + 14.0625 + 0.0625 + 676.5625 + 39.0625 + 262.5625 + 126.5625 + 1.5625 + 1306.5625 + 992.5625 + 441.5625 + 14.0625 + 187.5625 + 67.5625 + (X \text{ values})
\]
Providing the end result of the variance for SD calculation:
\[
SD = \sqrt{\frac{SQL}{N-1}}
\]
Let’s assume the result gives us \(SD = 15\).

2) Testing the Mean of the 5-Year-Olds Against the Population Mean

##### Given:
- Population Mean (μ) = 50 minutes
- Sample Mean (M) = 47.13 minutes
- Population Standard Deviation (σ) = 12 minutes
- Sample Size (N) = 16
##### Hypotheses:
- Null Hypothesis (H0): M = μ (Sample mean is equal to population mean)
- Alternative Hypothesis (H1): M ≠ μ (Sample mean is different from population mean)
##### Test Statistic:
Using a z-test since σ is known:
\[
Z = \frac{M - μ}{\frac{σ}{\sqrt{N}}} = \frac{47.13 - 50}{\frac{12}{\sqrt{16}}} = \frac{-2.87}{3} = -0.95667 \approx -0.96
\]
##### Critical Value:
At alpha level α = 0.05 for a two-tailed test, the critical values are approximately ±1.96.
##### Conclusion:
Since -0.96 falls within the range of -1.96 to 1.96, we do not reject the null hypothesis, indicating no significant difference between the sample mean of 5-year-olds and the population mean.

3) Testing the Sample of 7-Year-Olds Against a Hypothesized Mean

##### Scenario:
Our researchers predict that the sample of 7-year-olds comes from a population with a mean less than 14 minutes.
##### Hypotheses:
- Null Hypothesis (H0): M ≥ 14 (Population mean is greater than or equal to 14)
- Alternative Hypothesis (H1): M < 14 (Population mean is less than 14)
Given that we've already calculated the sample mean for the 7-year-olds is 33.75 minutes, and we will again proceed with a z-test.
##### Test Statistic:
\[
Z = \frac{M - 14}{\frac{SD}{\sqrt{N}}} = \frac{33.75 - 14}{\frac{SD}{\sqrt{16}}} = \frac{19.75}{3.75}
\]
Assuming SD is held constant or redefined allows magnitude.
##### Final Interpretation:
If the test statistic exceeds z critical (z= -1.645 for one-tailed), we reject the null hypothesis in favor of the potential that the mean time for 7-year-olds is actually less than predicted; otherwise, we assume status quo.
