Description
Most people are experts in some area of information; however, they may not be knowledgeable about other closely related areas. How knowledge is generalized to hierarchically related categories was explored. Past work has found little to no generalization to categories closely related to learned categories. These results do not fit well with other work focusing on attention during and after category learning. The current work attempted to merge these two areas of by creating a category structure with the best chance to detect generalization. Participants learned order level bird categories and family level wading bird categories. Then participants completed multiple measures to test generalization to old wading bird categories, new wading bird categories, owl and raptor categories, and lizard categories. As expected, the generalization measures converged on a single overall pattern of generalization. No generalization was found, except for already learned categories. This pattern fits well with past work on generalization within a hierarchy, but do not fit well with theories of dimensional attention. Reasons why these findings do not match are discussed, as well as directions for future research.

Description
Incidental learning of sequential information occurs in visual, auditory and tactile domains. It occurs throughout our lifetime and even in nonhuman species. It is likely to be one of the most important foundations for the development of normal learning. To date, there is no agreement as to how incidental learning occurs. The goal of the present set of experiments is to determine if visual sequential information is learned in terms of abstract rules or stimulus-specific details. Two experiments test the extent to which interaction with the stimuli can influence the information that is encoded by the learner. The results of both experiments support the claim that stimulus and domain specific details directly shape what is learned, through a process of tuning the neuromuscular systems involved in the interaction between the learner and the materials.

Description
Theories of interval timing have largely focused on accounting for the aggregate properties of behavior engendered by periodic reinforcement, such as sigmoidal psychophysical functions and their scalar property. Many theories of timing also stipulate that timing and motivation are inseparable processes. Such a claim is challenged by fluctuations in and out of states of schedule control, making it unclear whether motivation directly affects states related to timing. The present paper seeks to advance our understanding of timing performance by analyzing and comparing the distribution of latencies and inter-response times (IRTs) of rats in two fixed-interval (FI) schedules of food reinforcement (FI 30-s and FI 90-s), and in two levels of food deprivation. Computational modeling revealed that each component was well described by mixture probability distributions embodying two-state Markov chains. Analysis of these models revealed that only a subset of latencies are sensitive to the periodicity of reinforcement, and pre-feeding only reduces the size of this subset. The distribution of IRTs suggests that behavior in FI schedules is organized in bouts that lengthen and ramp up in frequency with proximity to reinforcement. Pre-feeding slowed down the lengthening of bouts and increased the time between bouts. When concatenated, these models adequately reproduced sigmoidal FI response functions. These findings suggest that behavior in FI fluctuates in and out of schedule control; an account of such fluctuation suggests that timing and motivation are dissociable components of FI performance. These mixture-distribution models also provide novel insights on the motivational, associative, and timing processes expressed in FI performance, which need to be accounted for by causal theories of interval timing.

Description
Nearly seven decades ago, the US government established grants to the states for family planning and acknowledged the importance of enabling all women to plan and space their pregnancies, regardless of personal income. Since then, publicly-funded family planning services have empowered millions of women, men, and adolescents to achieve their childbearing goals. Despite the recognized importance of subsidized family planning, services remain funded in a piecemeal fashion. Since the 1940s there have been numerous federal funding sources for family planning, including the Title V Maternal and Child Health Services Program, Office of Economic Opportunity grants, Title XX Social Services Program, Title X Family Planning Program, Medicaid, and the State Children’s Health Insurance Program, alongside state and local support. Spending guidelines allow states varying degrees of flexibility regarding allocation, to best serve the local population. With nearly two billion dollars spent annually on subsidized family planning, criticism often arises surrounding effective local program spending and state politics influencing grant allocation. Political tension regarding the amount of control states should have in managing federal funding is exacerbated in the context of family planning, which has become increasingly controversial among social conservatives in the twenty-first century. This thesis examines how Arizona’s political, geographic, cultural, and ethnic landscape shaped the state management of federal family planning funding since the early twentieth century. Using an extensive literature review, archival research, and oral history interviews, this thesis demonstrates the unique way Arizona state agencies and nonprofits collaborated to maximize the use of federal family planning grants, effectively reaching the most residents possible. That partnership allowed Arizona providers to reduce geographic barriers to family planning in a rural, frontier state. The social and political history surrounding the use of federal family planning funds in Arizona demonstrates the important role states have in efficient, effective, and equitable state implementation of national resources in successfully reaching local populations. The contextualization of government funding of family planning provides insight into recent attempts to defund abortion providers like Planned Parenthood, cut the Title X Family Planning Program, and restructure Medicaid in the twenty-first century.

Description
Netflix has positioned itself at the forefront of the future of television with its original programming, which has been rolled out in greater and more frequent amounts just in the last couple of years. The streaming service has already experimented with creativity in ways most other shows and creators haven't, playing with the pacing of overall seasons as well as the length of episodes. So, too, Netflix has been at the forefront of increasing visibility for minority characters on television. Many of its shows incorporate racially diverse casts and depict lots of LGBTQ characters, a refreshingly realistic view of the world that many of its viewers have always lived in but haven't yet witnessed on television. Visibility and representation are critical concepts for analyzing minority characters on television. It is important for diverse characters to be seen, first and foremost, but also to be seen in positive or at least realistic lights. Care must be taken to avoid fulfilling stereotypes or tropes, and attention must be paid to what has happened to other characters who have come before. However, many of Netflix's portrayals of these characters, particularly bisexual characters, leave much to be desired. With the original dramas House of Cards, Hemlock Grove, Orange is the New Black, and Sense8, all of which include characters who identify as or behave bisexually, Netflix has been reluctant to use the specific word bisexual to describe characters, and many don't even identify their sexuality with a synonym for the term. Many of the bisexual characters that I identified died or were killed on the shows, and nearly all of them fulfilled stereotypes or tropes in some way. There were multiple scenes of threesomes or other distinctly kinky sexual encounters, which served to exoticize bisexuality and distance it from the more normatively viewed identities of heterosexuality and homosexuality. Ultimately, while Netflix's original programming has offered increased visibility to bisexual characters, it has yet to reflect the real community it seeks to portray. In particular, Netflix's refusal to label characters as bisexual is frustrating and limiting. It can be argued that this is a progressive move toward more ideas of sexual fluidity and a post-modern lack of sexual labels, but there are not enough depictions of identified bisexual characters on television yet for this to make sense. Until bisexual characters and their identities are not invisibilized or stigmatized, more work has to be done to ensure that bisexual people are represented fairly and accurately on television and in all media.

Description
More than 260 million people suffer from an anxiety disorder worldwide, with 40 million in the U.S. alone—18% of the American population. And that label includes everything from Social Anxiety and Posttraumatic Stress Disorder to phobias and Obsessive Compulsive Disorder. Thus, people with anxiety may not have a singular cause for their worry, but a myriad number of them that influence every aspect of their lives. And, that doesn’t include people who’ve never been formally diagnosed and don’t receive proper medication or therapy.
Unfortunately, medication has many possible side effects, and both medication and therapy are often expensive. However, there are alternatives for someone dealing with anxiety. This book proposal offers a range of solutions for anxiety management, from do it yourself techniques like guided imagery and yoga, to biofeedback devices like HeartMath, to research trials on Eye Movement Desensitization and Reprocessing, as well as Repetitive Transcranial Magnetic Stimulation. The idea was not to outline every potential solution for anxiety, but to educate people on available opportunities and empower them to take control.
Though anxiety can be managed and reduced, there is no cure. That’s because anxiety is a normal part of life, and in most cases a helpful evolutionary tool to keep people on track. But, when this anxiety becomes a burden on someone’s life, there is a plethora of alternative solutions available. Understanding anxiety and learning to manage it is not an impossible task. This thesis provides an introduction to the idea and then allows the reader to move forward on their own path as they choose.

Description
Although it has recently been demonstrated that source monitoring (SM) processes may mediate the relationship between working memory (WM) and false memories, little research has investigated whether the quality of monitoring processes can account for this reduction. In the current study, participants performed multiple false memory, WM, and SM tasks. Consistent with previous research, SM abilities mediated the relationship between WM and false memories (regardless of whether or not participants were warned of the illusions at encoding). High SM individuals were better able to recall contextual information from study to correctly reject lures, whereas low SM individuals were more likely to rely on the quality of retrieved details to reject lures. These results suggest that individuals low and high in SM abilities rely on qualitatively different monitoring processes to reduce errors, and that individual differences in diagnostic monitoring strategies may account for previous relationships found between WM and false memories.

Description
The Hunger Games is one of the best representations of trauma and PTSD within a fictional work. While none of the characters are specifically diagnosed with PTSD, all of those who undergo the games put in place by the Capitol experience various forms of trauma and find various methods of coping. We see characters such as Haymitch or the morphling victors turn to drugs and alcohol for their survival. Further, we see characters such as Wiress and Annie who have incoherent speech and who struggle to put their thoughts into words. Finally, there are characters such as Peeta and Katniss who fight to hold onto the slightest bit of hope to try and remain in the present and avoid flashbacks and nightmares that return them to the horrors of the past. However, despite all of these symptoms of PTSD and trauma that are present through all three books of the series, one of the most important aspects of recovery from trauma that is demonstrated is the power of the ability to reconnect, to yourself, to family and friends and to others who have also experienced trauma. This social aspect of reconnecting relationships is the focus I would like to take for my thesis because I believe that it is one of the most powerful and the most healing aspect of trauma and PTSD. It is the most beneficial when those around you understand your experiences with PTSD and trauma and they are the ones who are able to help you the most in remaining in the present and wanting to continue living.

Description
This work examines three common practices—yellowface in Cloud Atlas (2012), whitewashing in Star Trek Into Darkness (2013), and absence in Firefly (2002)—employed in popular science fiction that represent Asianness and disregard the Asian body. Though the creators purport to have progressive ideals at the center of their production choices, their works call on Techno-Orientalist and Orientalist tropes and divorce them from the Asian body, implicitly continuing the Orientalist argument of Western supremacy even in representing Asianness.
