Description
Restraint stress is the most commonly used laboratory stressor. It is difficult to characterize as psychological or physical, because past studies show psychological features, but the nature of confinement adds a physical dimension. This was the first study to investigate how experience with restraint stress affects brain response to the next stress without a physical burden. Pair-housed adult male rats were transported to a novel context and restrained or left undisturbed (6hr). The next day, rats were returned to the same context and were either restrained or left undisturbed in the context (n=8/group). After 90min, rats were euthanized to determine functional activation in limbic structures using Fos immunohistochemistry and to measure HPA axis reactivity through blood serum corticosterone levels. Regardless of day 1 experience, context exposure on day 2 enhanced Fos expression in CA1 and CA3 of the hippocampus, basolateral amygdala, and central amygdala. Conversely, other regions and corticosterone levels demonstrated modulation from the previous day's experience. Specifically, rats that were placed back into the restraint context but not restrained on day 2 showed enhanced Fos expression in the dentate gyrus suprapyramidal blade (DGSup), and infralimbic cortex (IL). Also Fos expression was attenuated in rats that received two restraint exposures in the IL and medial amygdala (MEA), suggesting habituation. Only the DG infrapyramidal blade (DGInf) showed enhanced Fos expression to restraint on day 2 without influence of the previous day. While context predominately directed Fos activation, prior experience with restraint influenced Fos expression in the DGSup, IL, MEA and corticosterone levels to support restraint having psychological components.

Description
Abstract: Behavioral evidence suggests that joint coordinated movement attunes one's own motor system to the actions of another. This attunement is called a joint body schema (JBS). According to the JBS hypothesis, the attunement arises from heightened mirror neuron sensitivity to the actions of the other person. This study uses EEG mu suppression, an index of mirror neuron system activity, to provide neurophysiological evidence for the JBS hypothesis. After a joint action task in which the experimenter used her left hand, the participant's EEG revealed greater mu suppression (compared to before the task) in her right cerebral hemisphere when watching a left hand movement. This enhanced mu suppression was found regardless of whether the participant was moving or watching the experimenter move. These results are suggestive of super mirror neurons, that is, mirror neurons which are strengthened in sensitivity to another after a joint action task and do not distinguish between whether the individual or the individual's partner is moving.

Description
Time spent alone is a topic that has been studied in great detail, particularly the manner in which it is spent and the effect it has during the adolescent stage of life. Similarly, stress levels in adolescents have always been a topic of interest because of the effects they could have on the individual later in adulthood. Oddly enough however, the two areas of study have never been looked at in relation to one another. This study will look at different types of alone time as possible stressors in a community sample (N=82) of adolescents transitioning to college. The data on time alone and stress levels was collected through diary reports over a period of 3 days. The analysis only yielded significant effects for females and only for specific categories. It was found that females experience the lowest amount of perceived stress when they are alone and want to be alone, they have more negative affect when their desired environment differs from their current situation, and more positive affect in both the alone incongruence and not alone congruence situations. These results indicate that only women experience stress and affect changes when they encounter different congruent and incongruent environments.

Description
The aim of this thesis was to explore whether major life changes can have a visual, perceptible impact on facial changes. The proposed mediation model suggested that changes in personality serve as a mediating factor between life experiences and facial changes throughout the lifetime. The proposed model was tested by examining (1) perceived personality changes, (2) perceived physical changes, and (3) major life changes in photos of individuals' old-aged faces compared to their respective younger faces. Participants in the current study viewed old and young photos of 29 Miss America pageant winners and rated how much each older face changed from its respective younger face on the following criteria: age change, overall change, personality change, and physical change. Responses were aggregated across participants for each target, and personality and physical items were separately composited into single measures of overall perceived personality change and overall perceived physical change. Results did not support the proposed model; however, some marginally significant correlations were found between the number of times the targets experienced a change in marital status and the appearance of being calm, feminine, and less changed in older age. However, these correlations were in the reverse direction from what was expected; further research is needed to understand how marital changes influence, and are influenced by, personality and physical changes. As a form of face perception, the processes underlying the proposed model are discussed in terms of possible social consequences. Further research is needed to explore whether changes in life events, such as the ones presented here, are related to specific facets of personality and physical changes, and how these perceptions translate to important social outcomes. Suggestions for future research pertaining to these issues are discussed.

Description
I propose that norms regulate behaviors that negatively impact an individual's survival and reproduction. But because monitoring and enforcing of norms can be costly, individuals should be selective about which norms they police and under what circumstances they should do so. Two studies tested this idea by experimentally activating fitness-relevant motives and having participants answer questions about the policing of norms. The first study examined a norm prescribing respect for status and another proscribing sexual coercion. Results from Study 1 failed to support the hypotheses; activating a status-seeking motive did not have the predicted effects on policing of the respect-status norm nor did activating a mating motive have the predicted effects on policing of the respect-status norm or anti-coercion norm. Study 2 examined two new norms, one prescribing that people stay home when sick and the other proscribing people from having sex with another person's partners. Study 2 also manipulated whether self or others were the target of the policing. Study 2 failed to provide support; a disease avoidance motive failed to have effects on policing of the stay home when sick norm. Individuals in a relationship under a mating motive wanted less policing of others for violation of the mate poaching norm than those in a baseline condition, opposite of the predicted effects.

Description
The Paradox of Fiction can be understood as the acceptance of three plausible but inconsistent claims: Claim 1. We are genuinely moved by fiction Claim 2. We know that what is portrayed by fiction is not actual Claim 3. We are only genuinely moved by what we believe is actual. Taken individually, we intuitively accept each of the claims, however, they form a contradiction when taken together. The issue at hand is although we observe many instances of fiction moving a spectator/reader to tears, we know that the grief we observe does not reference an existent entity. How can we grieve at the death of Mercutio in "Romeo and Juliet" when Mercutio never existed let alone died? How can we fear a monster we know exists only in the world of a film? Many theories have been proposed to dissolve this paradox, and I focus on the ones that approach the puzzle by rejecting one of the above three claims. I examine some of these theories and explain why they fail to solve the paradox, and in doing so I demonstrate that the Make-Believe Theory succeeds where the others failed. Make-Believe Theory rejects Claim 1 and I shall prove that although unintuitive, we are completely justified in claiming that we are not genuinely moved by fiction. Instead, when we are moved by fictions, we are moved in a similar way to how a child is moved in a game of make-believe.

Description
Prospective memory is defined as the process of remembering to do something at a particular point in the future after first forming a conscious intention. There are three types of prospective memory intentions; event-based, time-based and activity-based intentions. Research has suggested that activity-based is one of the dominant prospective memory failures that people self-report yet there is little research on this area of prospective memory. The current study focuses on how activity-based PM is influenced by the association between the match of internal context and intended action. According to previous research, similar context between intention formation and retrieval has been shown to facilitate prospective memory, which increases the execution of intentions. Based on literature, we hypothesized that there would be higher intention completion when the internal context matches the intended action to be completed in the future. Results showed that internal context affected activity-based intention completion significantly. However the interaction between internal context and the intended action did not significantly affect intention completion. Although we did not get the hypothesized interaction, the means do cross over showing the interaction pattern is there. We decided to treat this as a pilot study and replicate it with a well-powered experiment consisting of 560 valid participants.
