Researchers who have previously explored the relation of broad-based temperamental approach constructs, such as surgency/extraversion, exuberance, or behavioral approach sensitivity, to academic competence (AC) in early elementary school have often found conflicting results. Moreover, few researchers have examined the interaction between these approach reactivity constructs and effortful control (EC) in the prediction of AC. The goal of the current study was to examine the fine-tuned relations of different aspects of temperamental approach reactivity in early childhood (42 and 54 months; N=223), such as impulsivity, frustration, and positive affect, as well as EC, to AC during early elementary school (72 and 84 months). Examining the complex relations may clarify the literature using broad-based approach reactivity constructs. Temperament was observed in the laboratory when children were 54 months of age. Mothers and caregivers also reported on children's impulsivity at 42 and 54 months. School-related behavioral adjustment was reported by children, mothers, and teachers, and GPA was reported by teachers at 72 and 84 months. The results of the study indicated that positive affect, EC, and receptive language ability were the only unique direct predictors of school adjustment and/or GPA. Without EC in the model, only positive affect and vocabulary predicted AC. Frustration, positive affect, and impulsivity each interacted with EC to predict AC outcomes, such EC was only related to higher AC for children with high impulsivity or anger, or low positive affect. Additionally, positive affect and impulsivity interacted to predict GPA, such that impulsivity was positively related to GPA for children with high positive affect, but it was negatively, albeit nonsignificantly, associated with GPA for children with low positive affect. These results were found to be similar for boys and girls. Finding are discussed in terms of the developmental importance of early EC for academic competence for children who have high approach reactivity, as well as the interactive effects of dimensions of approach reactivity on academic achievement.

The purpose of this thesis study was to examine whether the "war on cancer" metaphor influences cancer perception and treatment decision. A total of 249 undergraduates (152 females) from a large southwestern university participated in an online survey experiment and were either randomly assigned to the control condition (N=123) or to the war prime condition (N=126). Participants in the control condition did not receive the metaphor manipulation while participants in the war prime condition received the subtle "war on cancer" metaphor prime. After the prime was given, participants read a scenario, answered questions related to the situation, and responded to demographic questions. The results suggested that, compared to participants in the no-prime condition, participants exposed to the war metaphor were more likely to (a) view melanoma as an acute disease, (b) choose chemotherapy over molecular tests, and (c) prefer more aggressive treatment. These findings illustrated the unintended consequences of the "war on cancer" slogan. The results were encouraging and in the predicted direction, but the effect size was small. The discussion section described possible future directions for research.

Previously we found that subjects ate less from a four-piece bagel than from the same bagel served whole. Here, we determined if subjects differed in their perception of the amount of food based on the number of pieces of food served and measured the effects of these judgments on the amount of food consumed. A total of 213 (140 male, 73 female) undergraduate students with a mean age of 19 years participated in this study. Subjects were shown a whole food and the same food cut into pieces and asked which they perceived to be larger either before or after consuming that food, or not asked at all. We found that subjects ate less from a whole bagel than from a four-piece bagel. Furthermore, significantly more subjects perceived the whole bagel to be more food when asked this question after consumption of the bagel than before. People may be more familiar with the amount of satiation expected from a whole bagel than the four-piece bagel and this perceptual bias may be influenced by recent exposure to food, which ultimately may affect food intake.

Introspective awareness refers to direct access to one’s own internal and subjective thoughts and feelings (Wimmer & Hartl, 1991). Two theories, simulation theory and theory-theory, have been used to understand our access to our mental states. Simulation theory (Harris, 1991) involves imagining yourself in another person’s situation, reading off of your mental state, and attributing that state to the other person. Theory-theory (Gopnik, 1993) involves an interrelated body of knowledge, based on core mental-state constructs, including beliefs and desires, that may be applied to everyone—self and others (Gopnik & Wellman, 1994). Introspection is taken for granted by simulation theory, and explicitly denied by theory-theory. This study is designed to test for evidence of introspection in young children using simple perception and knowledge task. The current evidence is against introspective awareness in children because the data suggest that children cannot report their own false beliefs and they cannot report their on-going thoughts (Flavell, Green & Flavell, 1993; Gopnik & Astington, 1988). The hypothesis in this study states that children will perform better on Self tasks compared to Other tasks, which will be evidence for introspection. The Other-Perception tasks require children to calculate the other’s line of sight and determine if there is something obscuring his or her vision. The Other-Knowledge tasks require children to reason that the other’s previous looking inside a box means that he or she will know what is inside the box when it is closed. The corresponding Self tasks could be answered either by using the same reasoning for the self or by introspection to determine what it is they see and do not see, and know and do not know. Children performing better on Self tasks compared to Other tasks will be an indication of introspection. Tests included Yes/No and Forced Choice questions, which was initially to ensure that the results will not be caused by a feature of a single method of questioning. I realized belatedly, however, that Forced Choice was not a valid measure of introspection as children could introspect in both the Self and Other conditions. I also expect to replicate previous findings that reasoning about Perception is easier for children than reasoning about Knowledge.

In recent years, the number of applications for admission to graduate education programs has increased. Researchers attempted to gain insight into this increase by examining student perception of the costs and benefits of pursuing graduate-level education. In order to gauge this perception, researchers administered an online survey to 151 subjects from Barrett, the Honors College at Arizona State University. Student perception was then compared to data released by ASU detailing actual costs and benefits of obtaining graduate-level education. Researchers' prediction that increased levels of parental education would be associated with more accurate estimates of the benefits of graduate-level education was correct at a statistically significant level. Further, being male was statistically significantly associated with an increase in starting salary overestimation.

Tempo control is a crucial part of musicianship that can provide an obstacle for novice musicians. The current study examines why novice percussionists increase their playing tempo when they increase their loudness (in music, loudness is referred to as dynamics). This study tested five hypotheses: 1) As actual tempo changes, listeners perceive that the tempo is changing; 2) There is a perceptual bias to perceive increases in acoustic intensity as also increasing in tempo; 3) All individuals, regardless of percussion experience, display the bias described in hypothesis 2; 4) Unskilled or non-percussionists increase or decrease produced tempo as they respectively increase or decrease loudness; and 5) Skilled percussionist produce less change in tempo due to changes in loudness than non-percussionists. In Experiment 1, percussionists and non-percussionists listened to metronome samples that gradually change in intensity and/or tempo. Participants identified the direction and size of their perceived tempo change using a computer mouse. In Experiment 2, both groups of participants produced various tempo and dynamic changes on a drum pad. Our findings support that both percussionists and non-percussionists, to some extent, display a perceptual bias to perceive tempo changes as a function of intensity changes. We also found that non-percussionists altered their tempo as a function of changing dynamic levels, whereas percussionists did not. Overall, our findings support that listeners tend to experience some integrality between perceptual dimensions of perceived tempo and loudness. Dimensional integration also persists when playing percussion instruments though experience with percussion instruments reduces this effect.

Human perceptual dimensions of sound are not necessarily simple representations of the actual physical dimensions that make up sensory input. In particular, research on the perception of interactions between acoustic frequency and intensity has shown that people exhibit a bias to expect the perception of pitch and loudness to change together. Researchers have proposed that this perceptual bias occurs because sound sources tend to follow a natural regularity of a correlation between changes in intensity and frequency of sound. They postulate that the auditory system has adapted to expect this naturally occurring relationship to facilitate auditory scene analysis, the tracking and parsing sources of sound as listeners analyze their auditory environments. However, this correlation has only been tested with human speech and musical sounds. The current study explores if animal sounds also exhibit the same natural correlation between intensity and frequency and tests if people exhibit a perceptual bias to assume this correlation when listening to animal calls. Our principal hypotheses are that animal sounds will tend to exhibit a positive correlation between intensity and frequency and that, when hearing such sounds change in intensity, listeners will perceive them to also change in frequency and vice versa. Our tests with 21 animal calls and 8 control stimuli along with our experiment with participants responding to these stimuli supported these hypotheses. This research provides a further example of coupling of perceptual biases with natural regularities in the auditory domain, and provides a framework for understanding perceptual biases as functional adaptations that help perceivers more accurately anticipate and utilize reliable natural patterns to enhance scene analyses in real world environments.

Highly publicized cases involving citizen fatalities due to police use of force raise questions about perceptions of danger. Arrest-related deaths due to weapons, accidental injuries, and natural causes remain high year after year. Communities are greatly affected, and mistrust with the police continues to increase when these situations happen. There seem to be inaccurate perceptions that may stem from implicit associations, stereotypes, and social learning. These psychological concepts may provide theoretical explanations of how decisions are made when police officers are faced with danger. Some elements of this decision-making process may include suspect characteristics, officer experience, and police sub-culture. In this review, race/ethnicity and socio-economic status are examined as factors that contribute to police use of force. Disparities in use of force data often involve young, Black males living in low-income neighborhoods. The stereotype that this group is more dangerous than others stems from underlying prejudices and previous situations where Black people are targeted more in certain areas. Training, education, and community outreach programs can assist in mending relations between police and affected communities. Acknowledging these inaccurate perceptions, making the adjustments to police training and community relations, and being open to exploration in future research of other minority groups will assist in eliminating prejudices and creating better connections between law enforcement and the community.

Synesthesia is a psychological phenomenon in which the stimulation of one sensory modality brings about a response from at least one other modality. There has now been about two centuries of official synesthesia research, yet the current era of study, about the 2000s on, has proven invaluable to our further understanding of how synesthesia works in our perceptive world. I myself have two forms of synesthesia: color-grapheme and lexical-gustatory. In this paper, I look back on my personal experience with synesthesia and review its history and its operational definitions and theories. I then aim to perform a small case study on my synesthesia, using current research to evaluate my observations. I believe synesthesia has the ability to tell us much about perception, subjectivity, language, and consciousness, and I investigate the potential implications that studying synesthesia could have for some of these fields.

The present study tested 1) whether children’s bedtimes, wake times, and sleep

durations change as they transition into kindergarten (TtoK), 2) if changes to children’s

sleep schedules were contingent on their pre-kindergarten (T1) napping status and if T1

bedtimes were related to fall (T2) and spring (T3) bedtimes and durations, and 3) whether

T1 sleep, changes to sleep from T1 to T2, and concurrent sleep quality were related to

academic achievement and participation in 51 kindergarteners. It was hypothesized that

1) wake times would be earlier and sleep duration would be shorter during kindergarten

(T2 and T3) than at T1, 2) children who napped at T1 would go to bed later and have

shorter sleep duration than their non-napping peers and T1 bedtimes would be positively

associated with T2 and T3 bedtimes and negatively associated with T2 and T3 durations,

and 3) more optimal sleep (e.g., consolidated, consistent, and high quality) would be

positively related to academic achievement and participation. Parents reported on

children’s bedtimes, wake times, and nap lengths during T1, T2, and T3. During T3

children wore actigraphs for five consecutive school nights and completed the Woodcock

Johnson tests of achievement (WJ-III). Teachers also reported on children’s participation

in the classroom during T3. Results demonstrated that bedtimes and wake times were

earlier at T2 and T3 than T1. Duration was shorter at T2 and T3 than T1. Additionally,

napping was unrelated to bedtimes and durations, but T1 bedtime was positively related

to T2 and T3 bedtimes and negatively related to T2 and T3 durations. Finally, T1 nap

length, change in bedtimes, and Actigraphy duration were negatively related to

participation. Actigraphy onset variability was positively related to participation.
