The current study investigated whether intermittent restraint stress (IRS) would impair fear extinction learning and lead to increased anxiety and depressive- like behaviors and then be attenuated when IRS ends and a post- stress rest period ensues for 6 weeks. Young adult, male Sprague Dawley rats underwent restraint stress using wire mesh (6hr/daily) for five days with two days off before restraint resumed for three weeks for a total of 23 restraint days. The groups consisted of control (CON) with no restraint other than food and water restriction yoked to the restrained groups, stress immediate (STR-IMM), which were restrained then fear conditioned soon after the end of the IRS paradigm, and stress given a rest for 6 weeks before fear conditioning commenced (STR-R6). Rats were fear conditioned by pairing a 20 second tone with a footshock, then given extinction training for two days (15 tone only on each day). On the first day of extinction, all groups discriminated well on the first trial, but then as trials progressed, STR-R6 discriminated between tone and context less than did CON. On the second day of extinction, STR- IMM froze more to context in the earlier trials than compared to STR-R6 and CON. As trials progressed STR-IMM and STR-R6 froze more to context than compared to CON. Together, CON discriminated between tone and context better than did STR-IMM and STR-R6. Sucrose preference, novelty suppressed feeding, and elevated plus maze was performed after fear extinction was completed. No statistical differences were observed among groups for sucrose preference or novelty suppressed feeding. For the elevated plus maze, STR-IMM entered the open arms and the sum of both open and closed arms fewer than did STR- R6 and CON. We interpret the findings to suggest that the stress groups displayed increased hypervigilance and anxiety with STR-R6 exhibiting a unique phenotype than that of STR-IMM and CON.

Over the past few years, the issue of childhood trauma in the United States has become significant. A growing number of children are experiencing abuse, neglect, or some other form of maltreatment each year. Considering the stressful home lives of maltreated children, the one sure sanctuary is school. However, this idea requires teachers to be actively involved in identifying and caring for the children who need it most. Traumatic childhood experiences leave lasting scars on its victims, so it is helpful if teachers learn how to identify and support children who have lived through them. It is unfortunate that teachers will most likely encounter children throughout their career who have experienced horrendous things, but it is a reality. With this being said, teachers need to develop an understanding of what traumatized children live with, and learn how to address these issues with skilled sensitivity. Schools are not just a place where children learn how to read and write; they build the foundation for a successful life. This project was designed to provide teachers with a necessary resource for helping children who have suffered traumatic experiences. The methodology of this project began with interviews with organizations specializing in working with traumatized children such as Arizonans for Children, Free Arts for Abused Children, The Sojourner Center, and UMOM. The next step was a review of the current literature on the subject of childhood trauma. The findings have all been compiled into one, convenient document for teacher use and distribution. Upon completion of this document, an interactive video presentation will be made available through an online education website, so that distribution will be made simpler. Hopefully, teachers will share the information with people in their networks and create a chain reaction. The goal is to make it available to as many teachers as possible, so that more children will receive the support they need.

The Centers for Disease Control and Prevention in the United States announced that there has been roughly a 50% increase in the prevalence of food allergies among people between the years of 1997 - 2011. A food allergy can be described as a medical condition where being exposed to a certain food triggers a harmful immune response in the body, known as an allergic reaction. These reactions can range from mild to fatal, and they are caused mainly by the top 8 major food allergens: dairy, eggs, peanuts, tree nuts, wheat, soy, fish, and shellfish. Food allergies mainly plague children under the age of 3, as some of them will grow out of their allergy sensitivity over time, and most people develop their allergies at a young age, and not when they are older. The rise in prevalence is becoming a frightening problem around the world, and there are emerging theories that are attempting to ascribe a cause. There are three well-known hypotheses that will be discussed: the Hygiene Hypothesis, the Dual-Allergen Exposure Hypothesis, and the Vitamin-D Deficiency Hypothesis. Beyond that, this report proposes that a new hypothesis be studied, the Food Systems Hypothesis. This hypothesis theorizes that the cause of the rise of food allergies is actually caused by changes in the food itself and particularly the pesticides that are used to cultivate it.

Anxiety is currently the most prevalent mental disorder in America with over 4 million people struggling with it every day. I am one of those millions. This book explores the multitude of coping mechanisms that I have learned and developed through my time with anxiety, covering everything from humor to finding the motivation to change. It is a creative non-fiction autobiography that depicts detailed moments from my own life that provide advice and tools for managing anxiety that are made accessible to people who may have completely different experiences from my own. While anxiety has always played a huge roll in my life, it wasn't until I got to college that I decided to finally begin taking the steps I needed to in order to see the changes that I wanted to see. I am a teacher, and every day I see many of my students battling with the exact pains and stresses that I always have. This book is for all of my future students as well as all the adolescents out there who feel like nobody really understands; the ones who all they need is a little direction and the confidence to know they're not alone.

Media and technology are integral parts of today’s society. Unlike in the past, most adults in the United States now have access to the internet via their own personal devices. Technology’s popularity does not stop with adults. The children of this generation are extremely knowledgeable when it comes to media and technology and are exposed to it at a very young age. This paper analyzes the effect that this exposure is having on early childhood development. The research shows that there are several benefits to children using technology at a young age. Some of these benefits include increased learning opportunities, preparation for future careers, and support for children with disabilities. However, there are also several challenges that technology can cause. Some of these challenges include increased violence, exposure to inappropriate content, sleep issues, and an increased chance of obesity. In addition to this paper, a resource website titled Toddlers and Technology was created. The purpose of this website is to give parents insight into the information that is available in regards to technology and child development. The website includes the benefits and challenges of children using technology, recommendations on how parents can combat the challenges, and a list of 10 educational apps for early childhood development.

For many years now, early word learning in children has been an important subject among many researchers. There are many ways in which children learn word-object pairings including using co-occurrences, forwards integration, and backwards integration. This study primarily focuses on backwards integration. Backwards integration entails using learned information to be able to recall a word-object pairing from a previous time. In this thesis, three different studies were conducted with children aged 3-7 years old. In the general task, children were presented with a computerized word-learning task in which they could track word-referent pairings using co-occurrence statistics, forward integration, and backward integration. The goal of Study 1 and Study 2 was to determine the best task design to study backwards integration. The goal of the final study, Study 3, was to provide preliminary data on backwards integration. The overall results indicate that a between subjects design is the most beneficial way to test backwards integration because as a group, children were learning when compared to chance. In addition, the results from Study 3 showed that children were not learning in the task. In general, this suggests that this task may have been very difficult for children to complete. One limitation of Study 3
was that there was a small sample size of only 29 children. In order to account for this, the sample sizes in Study 2 and Study 3 were combined. This combined data did show that children succeeded at the backwards integration condition. It is noteworthy to mention that backwards integration was above chance in Study 2 and in the Study 2 and 3 combination. Therefore, the overall results suggest that children may possibly be able to backwards integrate; however, no evidence of learning in any of the other conditions were present.

Abstract The purpose of this thesis to bring awareness to children who experience symptoms of ADHD to inform them they are not alone. In the form of a book that is intended for readers between the ages of 8 and 11 years old can help them realize they are not the only ones that struggle with ADHD. Children who read this book hopefully can relate to the story of Samuel. The intent is to allow children with ADHD to know that there are children who are like them. They should not feel alone and know that with supportive family, friends, and teachers they can have successful relationships. It is important for children to realize that even though they may behave different from their peer it is acceptable to be different. When faced with bullying they should stand up for themselves or let their parents and teachers know what is going on. Children should be able to talk with their parents, and friends. When faced with change as long as children have a support system they can adjust with time to the change. Keywords: ADHD, Children, Book, Fiction

The ability to regulate emotions, attention, and behavior develops early in life and impacts future academic success, social competency, behavioral problems, and psychopathology. An impairment in regulation is known as dysregulation. Past research shows that children of mothers with postpartum depression are more likely to show impairment in regulatory abilities. There is an established link in the literature between family support and maternal depression, which in turn can impact child behavior. However, further research is needed to explore the impact of family support on early childhood dysregulation in the context of maternal depression. Using a sample of 322 Mexican-American, mother-child dyads, two models were examined. Model one hypothesized family support would buffer the effects of maternal depression on child dysregulation at 24 months. Model 2 hypothesized that family support is related to child dysregulation through its effect on maternal depression. Results showed that increased family support was related to more child dysregulation when there were high levels of maternal depression. There was no evidence to support the hypothesis that maternal depression mediated the relationship between family support and child dysregulation.

Depression, anxiety, and suicidal thoughts or actions are on the rise in adolescents (National Institute of Mental Health, 2015; Bridge, Asti, & Horowitz, 2015). Parents, school administrators, and therapists are searching for resiliency factors with in at-risk groups to aid students in need. In previous work, Luthar and Zigler (1992) reported that intelligent youth are more resilient than less intelligent youth under low stress conditions but they lose their advantage under high stress conditions. This study examined whether intelligence (reflected in grade point average; GPA) and maladaptive (internalizing and externalizing symptoms) behaviors are negatively related in adolescents, and tested whether level of stress, reflected in emotion regulation and friendship quality, moderated that association. It also probed whether the relationships differ by gender. Sixth-graders (N=506) were recruited with active parental consent from three middle schools. Adolescents completed self-report questionnaires Regarding demo graphics, maladaptive behaviors, emotion regulation, and friendship quality, and GPA data were collected from the school. Regression analyses found that GPA was negatively related to externalizing symptoms. Girls with poor friendship communication report significantly higher maladaptive behaviors. This relation was more pronounced for girls with high GPAs, as predicted. Results support the theory that intelligent female adolescents are more reactive under adverse circumstances. Future efforts should follow students through middle school into high school to evaluate whether friendships remain important to adjustment, hold for boys as well as girls, and have implications for relationship interventions.

Affluent children have been previously understudied and considerably neglected in developmental research due to the notion that they are "low risk." There is limited empirical research exploring the effects of parent involvement in affluent youth: specifically, the importance of the adolescent's perception that their mother/father do not spend as much time with them as they would like. The goals of the study were to explore the role of this dimension of perceived parental involvement in anxious-depressed symptoms, somatic symptoms, rule breaking behaviors and substance use with upper-class suburban youth. The sample was taken from the New England Study of Suburban Youth Cohort (NESSY) (Luthar & Latendresse, 2005b) consisting of 252 high school students in the 12th grade located in an affluent community in the Northeast. Results showed that the participants who indicated their fathers could have dinner with them more often if they tried presented significant group differences in anxious-depressed symptoms, somatic symptoms, and rule breaking behaviors while substance use trended towards significant. Thus, these data demonstrate that parent-child relationships are not only important for infant and child development, but are also an integral part of development of adaptive behaviors during adolescence. In addition, the data suggest the benefits from having strong, supportive, and stable relationships with not only mothers but with fathers as well. Results from post hoc analyses revealed perceived absence of fathers at dinnertime affects the adolescent more than the perceived absence of mothers at dinnertime. Finally, teens who indicated a need to spend more dinnertimes with their father may be suffering from a lack of open communication and opportunities to discuss social and emotional issues that are conducive to adolescent development and adjustment.
