  • The Chinese abacus is a cultural invention that leads to the use of a hexadecimal numeral system (i.e., base 16, rather than the base 10 numeral system commonly used throughout the world). Therefore, the hexadecimal numeral system is a very unique cultural practice that few other cultures have. Choose the position of either a general psychologist or a cultural psychologist; then, as your chosen psychologist, generate an explanation for the capacity to use the hexadecimal numeral system. (Chapter 1)
  •  Your new job in a culturally diverse company requires you to figure out how to deal with this cultural diversity in such a way that yields the most benefits for the company. Your two options are to take the color-blind approach or the multicultural approach. Choose one, and justify your response based on the research presented in the textbook. (Chapter 1).

Week 7 Exercise: Prosocial Behavior

Much of what we tend to focus on when we study social psychology are topics that often have a negative connotation such as conformity, prejudice, aggression or obedience. A huge component of the study of social psychology; however, focuses on prosocial behavior – behaviors that focus on compassion and helping others. For this activity, you will focus on this more uplifting aspect of social psychology. Topics that fall under the area of prosocial behavior include altruism, helping, bystander intervention, empathy, and compassion, among others.

For this exercise, pick one day and seek to structure your thoughts and behaviors entirely around helping others. With each interaction or action you take, pause to think and ask yourself “is there a way I might help another here?” Hold a door for someone, offer your seat, share a smile, give a sincere compliment, show empathy to another, attempt to be more patient or understanding, etc. Your efforts should be in social settings that involve interactions with others (rather than something such as donating to a charity for instance). The goal is to be as thoughtfully prosocial in your interactions throughout the day as possible.

  • At the beginning of the day, jot down your general mood, feelings, attitude, etc.
  • Then throughout the day, whenever possible, carry a small notebook with you or make notes in an app on your phone to jot down meaningful encounters or experiences as you attempt to engage in prosocial behaviors.
  • At the end of the day, again reflect and take notes on how you feel, your general mood, feelings and attitudes, etc.
     

In a 5-7 slide PowerPoint presentation, not counting title or reference slides:

  • Summarize your experience. Describe the prosocial behaviors you engaged in, others’ reactions to these behaviors, and your assessment of any changes in mood, attitude, good fortune, or anything else of note you experienced.
  • Review what you have learned about human behavior in social settings this week in your readings and CogBooks activities. Connect what you learned or experienced through your day of conscious, prosocial behavior with the terms, concepts, and theories from your research. Integrate at least two academic sources (your assigned readings/resources can comprise one of these sources), citing any references used in APA format.
  • Describe any new insights you gained through this experience about your interactions with others on a daily basis, including any behaviors you wish to change or to continue.
  • Use the features of PowerPoint to your advantage to communicate your ideas – include pictures, audio recorded narration, speaker’s notes, video, links, etc. as appropriate to enhance your ideas.
  • Include an APA formatted title slide and reference slide. APA components such as an abstract, headings, etc. are not required since this is a PowerPoint presentation.

According to Cohen and Swerdlik (2018), Reliability means to be consistent. In psychometric terms, the meaning of reliability is based on when something is said to be consistent. The book defines “a reliability coefficient is an index of reliability, a proportion that indicates the ratio between the true score variance on a test and the total variance” (Cohen & Swerdlik, 2018, p. 141). Moreover, in testing and assessment there exist three sources of error variance such as test construction, test administration, and test scoring and interpretation. The text state that a measurement error is everything that is associated with the process of the variable being measured instead of the variable being measured (Cohen & Swerdlik, 2018). 

Internal consistency reliability coefficient = .92  

According to Cohen and Swerdlik (2018), states that internal consistency reliability is when a one can obtain an estimation of a test being reliable without creating a different form of the test nor administering the same test twice to the same individual (Cohen & Swerdlik, 2018). Furthermore, a test that has an Internal consistency reliability coefficient = .92 means that the item on the test must relate to one another and it also means that there exists a strong relationship between the content of the test. As I mentioned at the beginning of the post reliability means to be consistent. The higher the coefficient, the more reliable the test is. A .92 means that the test has excellent reliability and it is acceptable.

Alternate forms reliability coefficient = .82

According to Cohen and Swerdlik (2018), states that alternate forms are different types of test that are built to be parallel. Hence, the reliability of the alternate forms refers to “an estimate of the extent to which these different forms of the same test have been affected by item sampling error, or other error” (Cohen & Swerdlik, 2018, p. 149). An example we can use is when a person is given two different versions of the same test at a different time. 

Test-retest reliability coefficient = .50

According to Cohen and Swerdlick (2018), A test-retest reliability is when a test is administered twice at two different points of time. Moreover, one we have to evaluate the reliability of a test-retest that purport to measure is fairly stable over time (Cohen & Swerdlik, 2018).

The higher the coefficient, the more reliable the test is. .92 means that the test has excellent reliability and it is acceptable the higher, the greater. An Alternate forms reliability coefficient = .82 is still high reliability, and it is also acceptable. A test-retest is a correlation of the same test over two administrator which relates to stability that involves scores. The book states that the more extended time has, the higher the chances that the reliability coefficient will be lower. Therefore, the passage of time may be an error of variance (Cohen & Swerdlik, 2018). Thus, depending on what the individual has been through some traumatic event it may also create an error variance which will impact their score variance and which will change, and the reliability will be lower than if that individual did not have any traumatic event. Therefore, if it is below .50 is not considered to be a reliable test nor acceptable. The book also states that “If we are to come to proper conclusions about the reliability of the measuring instrument, evaluation of a test-retest reliability estimate must extend to a consideration of possible intervening factors between test administrations” (Cohen & Swerdlik, 2018, p. 146).

C. Rowan (peer 1)

Adolescence is known by the changes in cognitive, physical, and psychological development. These changes occur to adapt to what is happening around them and what is expected of them (Steinunn, 2008.) Therefore, this requires a person to adapt individually to the circumstances and the environment around them. In many cases this is referred to as context acting on the person and the person acting on the context (Steinunn, 2008.)

With this information we can understand that action and understanding will change in relation to the cultural environment that one was brought up in. For example, American and Chinese culture, the vast differences cause the development to differ. Where American culture is relaxed on education and moving at one’s own pace Chinese culture is strict causing study habits and commitment habits to differ (Graaff, 2014.) This information provides a clear understanding of how we must approach adolescence and the information they take in and process from their environment. 

Gender also influences physical and cognitive developments, such as the development of empathy between males and females. For example, development of empathy compared between boys and girls, the information shows that girls score higher in this area. The article also provided information showing that boys that are more physically fit show lower levels of empathetic concern (Graaff, 2014.) Gender causes difference in hormone levels which causes developmental changes to appear at different times throughout adolescence between men and women.

Though, it is difficult to pinpoint the physical change that signals adulthood as it is seen as subjective than an exact science (Broderick, 2014.)

L. Rinner (peer 2)

The physical and cognitive changes that a child goes through to become an adolescent are immense. The physical changes are marked by the beginning of puberty; otherwise known as the sexual maturation stage (Broderick & Blewitt, 2014, p.326). For girls, this means that the breasts develop, hips broaden, pubic hair grows, and they will have their first menstruation near the end of this process. Boys also develop pubic hair, testes and scrotum grow, their voices deepen, and near the end of their process they will experience their first ejaculation. According to Broderick and Blewitt (2014), same sex parent age of menarche/spermarche is usually indicative of when an adolescent will have theirs, but not always (p.326). In a study completed by Louis et al (2008), there was a positive correlation between the adolescent’s BMI and precocious puberty; defined as development of secondary sex characteristics at or before the age of eight in both boys and girls (p.198). Another study by Colon et al (2000) claimed a positive correlation between serum pesticide exposure (through food ingestion) and early breast development in girls (p.897). Therefore, environmental factors may be contributing to our children looking sexually developed at a very young age. Broderick and Blewitt (2014) say that these changes also come with a price later in life; children that experience early onset puberty are more likely to experience breast cancer and behavioral and mental health issues (p.327).

On the other side of development, a child must also determine their ideals. This is a major part of cognitive development. Figuring out who you are as a person can lead to changes in personality, moodiness, and anxiety in adolescents (Broderick and Blewitt, 2014, p. 344). This can be particularly difficult for LGBTQ adolescents. It is difficult and awkward enough trying to find yourself and place within society when you are in the majority. LGBTQ adolescents feel even more different and unusual than average, thus leading them to engage in more risky behaviors than their cisgender/heterosexual counterparts (Broderick and Blewitt, 2014, p.414).

In conclusion, we have all gone through puberty and comprehend what adolescents feel when they are going through it. Hopefully, one day sexual, physical, and cognitive development will not be a social taboo and we will be able to make this process as comfortable as possible for our youth.

have been pretty much overcome.

3. A. Children’s intelligence is mainly inherited from their parents.

B. Children’s intelligence is mainly produced by their environment.

4. A. Most preschool children are more strongly attached to their opposite-sexed parent than to their

same-sexed parent.

B. Most preschool children are more strongly attached to the parent who provides the most nurturance.

5. A. Parents must provide infants with an especially stimulating environment to promote cognitive

development.

B. Infants actively seek stimulation and receive enough for good cognitive development from most normal environments.

6. A. Children think about the world in a completely different way than adults do.

B. Children’s minds are basically like adults’ minds, except that they don’t know as much yet.

7. A. Children learn most behavior by imitating adults and receiving approval for some things they

do and disapproval for others.

8. A. Most psychological problems in adulthood are caused by heredity.

B. Most psychological problems in adulthood are caused by the environments people grow up in.

9. A. Children’s relationships with their parents determine what their later relationships with other

people will be like.

B. Each type of relationship is different; adult relationships aren’t influenced much by people’s relationships with their parents.

10. A. Parents should be especially careful about how they wean and toilet train their children

because these events have a big influence on people’s personalities.

B. Weaning and toilet training are no more important in children’s development than anything else that happens in infancy.

The discussion post this week asks us to discuss data screening. Data screening is a way to go through your data, looking for errors that might need to be fixed prior to running analysis. Data screening is done to look for errors in data entry, outliers, and missing data. Errors in data entry can occur during data collection or when the data is entered into the system. When data is collected from a sample group, especially with self-answer data, it is possible that data may be incorrectly written down. This could occur as simply as the individual missing a line or missing a question on the survey. Alternatively, the data received may have been erroneously entered into the system. Missing data also seems to be clear in that it is data that is literally missing from the fields. SPSS can replace missing data with reasonable estimates based on the known data (Warner, 2013). Lastly, the outliers. These are data that is extremely high or extremely low based on the average of the data collected. Some scientists use the standard deviation of the mean and accept a certain number higher and lower as permittable while considering numbers outside of this range outliers. There is a risk to doing this to frequently as the researcher can create any number set of his data that he wants to “fit” by manipulating his numbers. It is recommended that one should not simply delete marginal data as it could lead to type 2 error, or falsely identifying outliers when none exist. This can lead to bad results (Spectroscopy, 2018).

Anderson & Bushman (2001) conducted the meta-analysis, Effects of Violent Video Games On Aggressive Behavior, Aggressive Cognition, Aggressive Affect, Physiological Arousal, and Prosocial Behavior: A Meta-Analytic Review of the Scientific Literature, which determined that there was a correlation between playing video games and aggressive behaviors. In a set of 21 controlled experimental studies, Anderson & Bushman (2001) concluded that there was a correlation between playing video games (x) and engaging in the aggressive behavior (y). Table 1 determined that aggressive behavior was measured at r= .19, therefore concluding that the correlation was statistically significant due to a large number of participants that were involved in the research study. Aggressive behavior in conjunction with playing violent video games was tested with 3,033 participants. If there was a smaller sample size (in this case, less than 3,033 participants), the correlation r=.19 may not have been as large or as significant. This result also yielded significant results because r=.19 is positive, rather than negative. In Table 1 it can also be determined that the results displayed significant results because of the homogeneity test. The homogeneity test determined an outcome of x2(32)  23.25, p > .05 (Anderson & Bushman, 2001). It was measured that the p score was 23.25, compared to the normal value used by SPSS and researchers, which is .05. Because the p-value was larger than .05, it yielded significant results for this research study. If the p-value was smaller than .05, it would not hold the same level of significance.

Peer 2 Response: Teddick

A meta-analysis (Anderson & Bushman, 2001) reported that the average correlation between time spent playing video games (X) and engaging in aggressive behavior (Y) in a set of 21 well-controlled experimental studies was .19. This correlation was judged to be statistically significant. In your own words, what can you say about the nature of the relationship?

Warner (2013) explained that in a result of .19 will fall among the small (r<.10) and the medium (r<.30) and in less than the large (r<.50). This is an indicator that there is a compelling association, but this does not mean there is a causation between aggressive behavior and video games. Because of the insufficient information provided, we must consider every factor that contributes to the research, for example age of the gamer, time spent playing, time spent watching movies of violence, how much the parents are involved in their child’s life, if that person is involved with the wrong group of individuals, their surrounding neighborhood, and even their social and academic intellect. However, there still is a relationship of correlation on the meta-analysis, but does not necessarily means a causation. The meta-analysis shows a significant association on aggressive behavior being affected by playing violent video games, but does not prove or show that it causes the behavior. If anything it does encourage parents to look for more age appropriate video games and limit the access of violent-themed games for their kids (Anderson, C. & Bushman, B., 2001).

Brain and Cognitive Changes in Late Adulthood-Tequilla DeVaughn

COLLAPSE

According to Broderick and Blewitt (2015), “One way to make sense of the mixed pattern of improvement and decline through adulthood is to categorize cognitive skills with regard to how heavily they depend on two kinds of underlying intellectual resources: fluid and crystallized intelligence” (489). Fluid intelligence has been described as being the mechanics of intelligence, a measurement of how well hardware is operating, including functions like speed process (Broderick and Blewitt, 2015) in addition to reasoning and problem-solving abilities (Manard, Carabin, Jaspar, & Collette, 2014). Thus, it seems relevant to assume that individuals with high fluid intelligence should be more disposed to use proactive control to maintain task-goals in an active state in order to more efficiently manage declining effect (Manard, Carabin, Jaspar, & Collette, 2014). This is sufficient information to consider when it has been noted previously that after age 40 declines become more rapid (Broderick& Blewitt, 2015). Moreover, one must note that executive functions are closely linked to fluid intelligence and include working memory, self-regulation, and cognitive flexibility (Broderick & Blewitt, 2015).

On the other hand, crystallized intelligence, also known as the pragmatics of intelligence, is the compilation of skills and information we have gained over a lifespan (Broderick & Blewitt, 2015). Furthermore, this category of intelligence is a little like the saying, “it’s like riding a bike” because the strategies we have learned for memorizing information or solving problems, forms of declarative and procedural knowledge, is less likely than fluid intelligence to show declines with age and, for some individuals, can increase even into old age (Broderick & Blewitt, 2015). Crystallized intelligence represents knowledge and skills acquired through education and experience in several domains (Thorsen, Gustafsson, & Cliffordson, 2014).

However, this information can be essential to professional’s aid in positive adjustment for aging adults because it provides and understanding of what may be happening on a cognitive level. Thorsen, Gustafsson, & Cliffordson expresses that an integrated model of cognitive, differential, and developmental theories notes intelligence as a function that causes development of understanding, learning, reasoning, and problem-solving.  The model also argues that development in understanding, learning, reasoning, and problem-solving is in large dependent on the increase in mental efficiency and capacity (Thorsen, Gustafsson, & Cliffordson, 2014). All in all, utilizing this information will help one identify the cognitive experiences that may be taken place and therefore aid in affective planning and interactions.
