Ecological validity

general area of body dissatisfaction and media images has its limitations too. According to Sparks (2013), Alan Roberts and Emily Good reported that the harmful effects of media images might not be as widespread as what we used to believe. In fact, recent research suggested that the harmful effects of media exposure to thin body images seemed to happen mainly for women who are high in neuroticism. This implies that the majority of women would not be affected by media exposure to thin body images. This may be a potential problem for my proposed media research because it would be difficult to identify my research participants into groups that are characterized with high neuroticism or low neuroticism. It also affects the external validity and ecological validity of my proposed research, because each individual are characterized with different levels of neuroticism. And thus, would be difficult to generalize the result of the research to other populations. I would consider using both the experimental method and survey in this study. In my opinion, the use of the experimental method and survey are the best research methods for this study. Through the use of a pre-test and post-test experiment with a treatment and a control group, one would be able to show the effect of exposure to diet product ads models on college male students. However, one should take into account that the result of this experiment is probably not generalizable to all college male students since each…

Ecological validity is the extent to which psychological research and experiments mirror the events of real world situations. This essay will present examples in historical and recent psychological research and evaluate the role of ecological validity in each. In doing so, other key elements to psychological research will also be approached. Firstly, this essay will look at the experiments of Bandura et al. who sought to investigate the effect of social learning and aggressive behaviour in…

ADHD patients. The subjects of the MTA study were recruited at six sites across the U.S. from diverse resources including newspapers, physicians, clinics, schools, parent referral and more. Among five hundred seventy-six boys and girls, the age range was only between 7 to 9 years old. The decision was made in order to group children in the BT group effectively; yet, this limited the external validity of the study. However, with such broad sample pool, in terms of their background, location,…

In addition to your assigned article you will need to use your textbooks or other resources to adequately talk about the specific aspects of having validity in a research study. Validity is affected by low statistical power. As stated above, a power analysis was unable to be conducted for this study. Grove, Burns & Gray (2016) state: Low statistical power increases the probability of concluding that there is no significant difference between samples when actually there is a difference (Type…

A model which parallels numerous symptoms of human depression is considered important. It is well known that animal models should share phenomenological similarities isomorphism with the human pathology to be modeled. In other words we can say that it is phenomenological similarities between the behavior shown by the animal model and the particulars symptoms of the human condition (Geyer and Markou 1995; Moreau 2002; Lyon 2004) .The face validity of animal model of depression is a determination…

work with their killer whales. In response Sea World published, on their website, an article titled "Truth about Blackfish". The article attempts multiple times to discredit "Blackfish" by using weak arguments and deception. These strategies fail by the end of the article and leave the readers unconvinced that Sea World is not harming their own killer whales. As a result they also failed to change the readers perceptions about "Blackfish" being a Documentary. Sea World had multiple opportunities…

and any variation and comparison procedures for all administered batteries (LaForte, McGrew, & Schrank, 2014). Furthermore, LaForte, McGrew, and Schrank (2014) states the WJ IV is based on the theoretical foundation from the Cattell-Horn-Caroll theory of cognitive ability and evidence to support the interpretation of the WJ IV, Validity Content was addressed using the master-test and cluster-content according to the CHC theory. The Content validity refers to the learning area measured by the…

construct validity, the GAI’s truthfulness scale was compared with the polygraph exam and it indicated a positive correlation between the two. Concurrent validity procedures included administering a test and comparing the test results to criterion performance. It is important to take into consideration any cultural bias or other social factors related to the assessment. For example, Chinese cultures have values and beliefs that favor gambling. Hence, they will not rate the severity of their…

Appendix B). Validity and Reliability An instrument is valid when it measures the construct it was designed for, and reliable when an instrument can consistently produce the same results over time, across different situations (Field, 2003). Content validity is an evaluation of the relationship between the items and the construct being measured (Cook & Beckman, 2006) and can be done in two ways. Firstly, a thorough revision of the construct would be required to avoid any ambiguities when…

A panel of experts is needed to review the instrument, and determined the validity and reliability. The group discussion was an example of panel of experts, who determined the content of validity and reliability between the items composing in the instrument. The reliability was conducted before the expert panel review, which for this assignment were my classmates. The panel of experts provided suggestions with regard to improving the instrument’s readability (Sharma & Petosa, 2014). My…
