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
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
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.

Description
This research explores how to best communicate positive body images to women. This project was intended to improve a blog I created my freshmen year in college called You're Not A Potato where I used original illustrations to tell a narrative about body image issues. The thesis begins with an historical overview of body image issues and finds that women have been dealing with high levels of body dissatisfaction since the Victorian era. The thesis then recaps the role of traditional media as well as contemporary social media and the role they play in imposing rigid beauty ideals on women's bodies. After an analysis of social media culture, it becomes evident women still communicate about their bodies in a negative manner, not only towards themselves, but towards others. To address this issue, I define the Body Positive movement and explore how public figures are using social media to implement Body Positivity. To conclude this project, I utilize my new-found knowledge in body positive communication by impacting my university campus community. I started a "You're Not a Potato" Campaign for Body Pride week with the help of the ASU Wellness Team and designed and facilitated several engaging programs that reflected the values of the Body Positive movement to our students. Through this research, I discovered how our appearance-based culture has stolen self-confidence from young women today, but by the end of this project, I explain how we can attempt to rebuild our culture by effectively communicating self-love and body acceptance in our online and physical communities.

Description
It is a well-established finding in memory research that spacing or distributing information, as opposed to blocking all the information together, results in an enhanced memory of the learned material. Recently, researchers have decided to investigate if this spacing effect is also beneficial in category learning. In a set of experiments, Carvalho & Goldstone (2013), demonstrated that a blocked presentation showed an advantage during learning, but that ultimately, the distributed presentation yielded better performance during a post-learning transfer test. However, we have identified a major methodological issue in this study that we believe contaminates the results in a way that leads to an inflation and misrepresentation of learning levels. The present study aimed to correct this issue and re-examine whether a blocked or distributed presentation enhances the learning and subsequent generalization of categories. We also introduced two shaping variables, category size and distortion level at transfer, in addition to the mode of presentation (blocked versus distributed). Results showed no significant differences of mode of presentation at either the learning or transfer phases, thus supporting our concern about the previous study. Additional findings showed benefits in learning categories with a greater category size, as well as higher classification accuracy of novel stimuli at lower-distortion levels.

Description
My thesis will revolve around the ideology and sociology of the sneaker brand and it particular, basketball sneakers. The mega sneaker superpower Nike and the under dog of Under Armour have shoes they want to sells and consumers they want to buy them. I will discuss how the advertisement are used and implanted but both Nike and Under Armour. The two points of references from each company will be LeBron James, Nike, and Stephen Curry, Under Armour. Both basketball players have signature shoes and are undoublty the NBAs most relevant players this past season. The two players just so happened to face off against each other in the NBA finals, which enhanced the marketing potential for both companies. Thus, the advertisements for these and their shoes would have been its peak trying sway consumers to either side. Nike and Under Armour both ploy attempts in creating marketing material to attract their consumer base. The Thesis will look at why sneakers have become a social trend and high commodity. I will look at how pop culture and psychological diseases play a roll in the consumers' choice to purchase either shoe. The work as a whole will attempt to bring forth some revitalizing information on today's sneaker culture. Research was limited, however with the information to conduct this thesis, the thesis should spark interest in a new research related field. Thus, bringing forth a new renaissance in today's culture; the Sneaker Life.
