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
The purpose of this project is to raise awareness for children with social anxiety. As a book directed to children around the age of 12, it will give them a character they can relate to, so they can feel less alone. Throughout the story, the main character experiences symptoms of social anxiety and is subject to events that exacerbate those symptoms. Despite her challenges, the main character is able to effectively cope with her social anxiety through her own hard work, and help from her family members, teachers, and peers. The intent is to show children with social anxiety that, contrary to what their disorder makes them feel, they are special and have the capacity to develop skills that are relevant to their talents and interests, and overcome their fears. They should know that parents, teachers, and peers will be there to help and support them and will not judge them as harshly as they suspect. The supporting characters in this story show how a strong support base can influence the success of children with social anxiety. By the end of the story, the main character still has social anxiety, but has gained confidence and her symptoms are less severe. This illustrates that, although social anxiety cannot simply be overcome—that is, it doesn’t go away completely—it can be effectively managed with assistance from close others, and perseverance.

Description
Impostor Phenomenon (IP) is defined as an occurrence in individuals who have difficulty internalizing success, and live in constant fear of the "mask being unveiled," or being exposed as a fraud (Clance, 1985). It is estimated that 70% of the population will experience at least one episode of Impostor Phenomenon in their lifetime. (Gravois, 2007) This study surveyed 120 first-time freshmyn at Arizona State University West campus to gain access to demographic information, first-year programming attendance, and their Impostor Phenomenon scores using the Clance Impostor Phenomenon Scale. After the data was analyzed, it was determined that there were no significant findings between Impostor Phenomenon scores, honors status, and generational status, nor were there statistically significant findings when compared against age, gender, and first-year programming attendance. The average score for all students surveyed ranged in the "frequent bouts" of Impostor Phenomenon, which is the third-highest level of Impostor Phenomenon. Although there are no statistical differences between the identified groups, it is important to note that the average scores are high, and that changes can be made to first-year programming to help lower the average Impostor Phenomenon scores. Teaching students self-compassion is one way to address the common symptoms of Impostor Phenomenon. In addition to background on self-compassion, this thesis offers suggestions on how self-compassion teachings could be incorporated into first-year programming to make students more comfortable and confident during their first year at Arizona State University.

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
A home holds so much more meaning and power than the physical structure of a house. As much as our personal space serves as an extension of ourselves, it also affects us. Furthermore, whichever state a home environment is in has a major impact on psychological well-being. This thesis is an investigation of the idea of home design as a means of addressing psychological anxiety through the point of view of a college student. The information is divided into three chapters; which are Overview of Relevant Scholarly Literature, Design Philosophies, and Personal Experience. Within the scholarly literature, well-being and anxiety are two trends in the studies of environmental psychology, positive psychology, and the humanities. There is still limited knowledge in these areas, so it is important to expand the understanding of the home environment's influence. Based on this research, well-known philosophies, and personal experience, design philosophies are an effective way to potentially improve well-being and reduce anxiety, especially for college students. While Hygge and Wabi-sabi are both design philosophies rising in recognition, Feng Shui is already widespread around the world. Some of the recommendations discoverer were to add cozy décor and lower lighting options to soften the room, get rid of extra clutter taking up space, or bring in nature with greenery and fresh flowers. However, these objects have countless interpretations and there is not a single correct answer. In the end, adjusting the space to be individualized will bring more comfort and these efforts will begin to make a difference in the user’s state of mind.

Description
Animal psychology is the study of how animals interact with one another, their environment, and with humans. This can be done in two different settings, the wild and captivity, and through two different approaches, academic research and practice. Academic research relies primarily on behavioral observation for data collection. Practice uses behavioral observation as well, but allows for a more hands on experience and lets the practitioner make improvements in the quality of life. I interviewed two people, one who practices in captivity, and one who does research in the wild. Dr. David Bunn has done research on wild animals in Kruger National Park in South Africa for over twenty years, studying human-animal interactions. Hilda Tresz has worked in zoos nearly forty years and specializes in chimps. Working within the same field, but utilizing a different setting and approach makes a big difference in the feel of the job. Though I found many differences between the two by doing my own research and from conducting interviews, there are many similarities to note as well. The general field of animal psychology is very rewarding, requires a lot of patience, and leads to a better understanding of animal behavior and how to care for specific species of animals. Working with captive animals allows for the opportunity to make a big difference in animal's lives through behavioral enrichment and general care. Working in the wild allows us to understand the innate animal behaviors displayed. Through practice, people get more hands on experience; while through research, you get to observe animals in their native habitats. Each setting and approach has it's own benefits depending on what each person's goals are for their job.

Description
The purpose of this thesis is to examine the relationship between mental illness and capitalist consumer society. Many Americans are suffering from mental illness and there has to be something causing it besides a chemical imbalance in the brain. A capitalist society creates a set of expectations that conflict with human desires. The thesis takes a historical, economical, and psychological approach to answering the following question: Does a capitalist society make its citizens mentally sick? A brief history of capitalism over the past century is discussed, as well as a more in depth look at capitalism and the creation of neoliberalism during the 1980s. The psychological effects capitalism has on human beings is discussed for the majority of the thesis and focuses on ideas from the 1950s as well as the early 2000s. To show the effect capitalism has on modern day society, an analysis of a psychopharmaceutical drug commercial is given. The concluding thoughts attempt to offer solutions to the problems of human unhappiness in a consumer culture.
