A clinical psychologist who works with individuals also conducts research. This clinician is interested in the impact of attachment style on a person’s perceptions of their mothers. The researcher administered an attachment style questionnaire to 18 participants and based on the results categorized them into one of 3 distinct groups: secure, avoidant, or anxious. Those that are securely attached easily get close to others while those that are avoidant tend to value independence and freedom, and those that are anxious have difficulties trusting others. The researcher then asks all participants to rate their mothers on a scale measuring the degree to which they perceive their mother to be malevolent (spiteful) with higher scores meaning higher malevolence. The results are presented in the table below. Using the 0.05 alpha level and all the steps of hypothesis testing, is there a significant difference in perceptions of their mother’s malevolence depending on how attached they are?
| Secure | Avoidant | Anxious |
| 3 | 5 | 10 |
| 2 | 7 | 12 |
| 4 | 8 | 11 |
| 1 | 6 | 10 |
| 0 | 9 | 13 |
| 2 | 6 | 12 |
please explain the methods you have used as I do not understand the extact steps to take when calculating a hypothesis. Thank you so much for your effort and time in advance.

- Swedish researchers concluded that viewing and discussing art soothes the soul and helps relieve medical conditions such as high blood pressure and constipation. This conclusion was based on a study in which 15 elderly women gathered once a week to discuss different works of art. The study also included a control group of 15 elderly women who met once a week to discuss their hobbies and interests. At the end of 4 months, the art discussion group was found to have a more positive attitude, to have lower blood pressure, and to use fewer laxatives than the control group. (a) Why would it be important to determine if the researchers assigned the women participating in the study at random to one of the two groups? Assigning women at random satisfies the conditions of a single-blind experiment. 2. Assigning women at random is not important for the study and can be neglected. 3.Assigning women at random ensures that the two groups are comparable.

An article discusses the social forces that influence forest management policies in three Indian states: Haryana, Bihar, and Uttar Pradesh. The forest quality in Haryana is somewhat degraded, in Bihar it is very degraded, and in Uttar Pradesh it is well-stocked. In order to study the relationship between educational levels and attitudes toward forest management, random samples of adults in each of these states were surveyed and their educational levels were ascertained. The numbers of adults at each of several educational levels were recorded. The data are presented in the following table (see image). A.Find the P-value B.State a conclusion.

- Motivational speakers want to be perceived as trustworthy. One hypothesis is that speakers who exhibit immediacy behaviors such as making eye contact, smiling and leaning forward might be perceived as more trustworthy than those who do not engage in these behaviors. To test this hypothesis, a psychologist obtained data from 26 participants. For people in a non-immediacy group, the speaker did not engage in any immediacy behaviors. For the immediacy group, however, the speaker made eye contact, smiled and leaned forward while giving a speech. After the speech, participants rated the speaker on a scale of trustworthiness ranging from 1 (not at all trustworthy) to 9 (highly trustworthy). The following data were obtained. Test whether the immediacy behaviors of the speaker affect trustworthiness rating.

Thomas Boyce, a professor and pediatrician at the University of British Columbia, Vancouver, has studied interactions between individual differences in physiology and differences in experience in determining health and well-being. Dr. Boyce found that some children are more sensitive to their environments. They do exceptionally well when the environment is supportive but are much more likely to have mental and physical health problems when the environment has challenges. You decide to do a similar study, conducting a factorial experiment to test the effectiveness of one environmental factor and one physiological factor on a physical health outcome. As the environmental factor, you choose two levels of stressful life events. As the physiological factor, you choose three levels of immune reactivity. The outcome is number of respiratory illnesses in the previous 12 months, and the research participants are kindergartners.arrow_forwardA research firm reported that 15% of those surveyed described their health as poor, 26% as good, 40% as very good, and 19% as excellent.

- Recent research is exploring ways to use virtual reality (VR) to help people in a variety of ways. In one published study, researchers examined whether VR could help people get over the discomfort they feel after riding rollercoasters. Participants whose lifelong dreams were to ride rollercoasters without feeling noxious were recruited to participate in the research. Some participants were randomly assigned into the control group, where no VR treatment was provided before riding the rollercoaster (instead, they received an encouraging pep talk from the experimenter). The rest of the participants were put in the treatment group, where they first put on a VR headset and experienced a virtual rollercoaster before riding the real thing. After both groups of participants completed the rollercoaster ride, both survey and physiological measures were collected. The subjective and objective measures for each participant were summed to create a discomfort index, which ranges from scores of 1…arrow_forwardIn an early study of the effects of frustration on feelings of hostility, Miller and Bugelski (1948) had a group of boys at a camp rate their attitudes toward two groups (Mexicans and Japanese).

A psychologist wants to evaluate the effectiveness of dialectical behavior therapy (DBT) on BPD in a two month study. The psychologist randomly selected 500 people who have BPD to participate in a study. The 500 participants were divided into two groups based on gender. The first group, contained 344 females, they were given medication along with DBT therapy. The second group were comprised of 156 males, they received medication alone. At the end of the two month study, the psychologist administered a standard test to evaluate the symptoms of BPD. It was found that the group that received the DBT therapy along with the medication had about the same level of improvement in symptoms as the group that received the medication alone. The psychologist concluded that there is no evidence that DBT therapy is effective at improving the symptoms of Borderline…arrow_forward
