Description
As the population of the United States grows, child maltreatment will remain a constant problem in our society. Current victimization theories do not portray a clear picture of the factors and influences of victimization associated with children. By combining routine activities and lifestyles theories, a full picture of maltreatment emerges that can be applied to a wide range of types, areas, and victims. It is possible that the current policy on victimization and crime can be changed to incorporate this new view of maltreatment. Further research needs to be done to understand the applicability of such a theory and if high-risk populations will benefit.

Description
Evidence thus far has not lent credence to facilitate lie detection by the average person. According to studies, there are five major signs of lying: lip pursing, narrowed eyebrows, shoulder shrugs, looking to the left, and smirking. The present study aims to determine whether training people in detecting the five signs of lying will facilitate lie detection in the average person. We analyzed the accuracy of lie detection by examining the verdicts of 155 undergraduate students during simulated police interrogations. Comparisons between the trained and untrained subjects support the hypothesis that the average person is no better than chance at detecting lies through non-verbal cues.

Description
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.

Often learning new skills, such as how to throw a basketball or how to play the piano, are better accomplished practicing with another than from self-practice. Why? We propose that during joint action, partners learn to adjust their behavior to each other. For example, when dancing with a partner, we must adjust the timing, the force, and the spatial locations of movements to those of the partner. We call these adjustments a joint body schema (JBS). That is, the locations of our own effectors and our own movements are adapted by interaction with the partner. Furthermore, we propose that after a JBS is established, learning new motor skills can be enhanced by the learner's attunement to the specifics of the partner's actions. We test this proposal by having partners engage in a motor task requiring cooperation (to develop the JBS). Then we determined whether a) the JBS enhances the coordination on an unrelated task, and b) whether the JBS enhances the learning of a new motor skill. In fact, participants who established a JBS showed stronger coordination with a partner and better motor learning from the partner than did control participants. Several applications of this finding are discussed.

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.

Description
This study analyzes various reasons why some Americans find the subject of ghosts and ghost hunting so fascinating. A recent poll suggests that nearly half of Americans believe in ghosts. Thousands of ghost hunting societies exist in which members try to find proof of a supernatural world. Hundreds of films featuring paranormal elements have been released over the past few decades. The prevalence of this subject warrants further investigation regarding its appeal. Ghost stories have been passed down from one generation to the next for millennia in literature and by word of mouth. There have been accounts of ghosts haunting homes and families all over the world. Edgar Allen Poe and Nathaniel Hawthorne introduced the American horror story, which is characterized by themes that strike Americans where they care most. These stories transgressed from literature into film and television where they began reaching widespread audiences and continue to exist and thrive today. However, for as long as there have been people interested in ghost stories, there have been those interested in ghost hunting. This hobby became widely popular in the late twentieth century when popular films made it acceptable to discuss the possibility of a haunting in the home. Reality television then showed that anyone could be an investigator. Even though the topic of ghosts can be frightening and disturbing to some, others find ghost stories and ghost hunting very appealing. The purpose of this study is to understand the motivations of these investigations and the attraction to these tales. Over the course of this research, two interviews with local ghost hunters were conducted to understand their unique perspective on the subject. Further, public forums were analyzed to determine popular opinions regarding these appeals. Psychologists have proposed various theories regarding the appeal of ghosts in popular media, which provides a theoretical framework for the public opinions gathered from the forums. There is very little research regarding the motivations of ghost hunting, which is alarming. Many people have decided to dedicate their lives to this hobby, so why has so little research been conducted on the subject?

Forensic pathologists investigate unnatural or suspicious deaths in medico-legal cases and must be accurate and thorough in their analyses so that justice can prevail. This occupation, however, is immensely difficult, and mistakes can occur. These challenges are discussed here with suggestions for improvement. Implementing new technologies, better quality control, more research, and standardization of procedures are just a few of the multiple changes that can enhance forensic pathology.

Description
The investigation of sex trafficking and prostitution related offenses are primarily handled by local police. Despite this, state and city level responses vary widely. This paper will examine the local law enforcement response in 11 geographically diverse police departments, focusing on their operational policies, investigative priorities, community connectedness, and the impact of the local economy on investigations. Implications for further research and policy recommendations will be given.

What characteristics do people prefer in potential mates? Previous studies have explored this question, discovering that preferred characteristics vary by people's sex and sexual strategy, but have implied that these preferences remain constant across the lifespan. We suggest, however, that systematic variation exists in individuals' mate preferences across the lifespan, as they shift their investments from mating toward parenting. We suggest that the characteristics of a potential mate can be viewed as affordances that assist or hinder an individual in achieving certain fundamental goals. Incorporating the framework of Life History Theory with this affordance-management approach to social behavior, we propose that an individual's life stage, sex, and life history strategy together serve as the basis for these goals and thereby shape the characteristics people seek in potential mates. Using data collected from participants aged 18-45 recruited on Amazon's Mechanical Turk, we tested a range of hypotheses derived from our approach. In general, results provide mixed support for a role of life stage in shaping mate preferences. For example, nurturance and social competence were viewed as more necessary characteristics in a mate by participants invested in parenting. Moreover, as their investment in mating increased, females expressed a greater preference for ambition in their potential mates, but males did not. Other predictions were not borne out, however, suggesting that there is still much to be learned from investigating the relationship between life stage and mate preferences.

Description
Alcohol use remains a large part of collegiate life and is a major public health concern. Alcohol use generally peaks during the early twenties and declines with age. These declines, referred to as "maturing out," are presumed to be the result of the acquisition of adult roles (e.g. marriage, parenthood, employment) incompatible with alcohol use. Recent empirical evidence suggests that variables other than role transitions (e.g. personality) during emerging adulthood may also be important in understanding this process. Conceptually, changes in identity that occur during emerging adulthood may also be linked to the process of maturing out of heavy drinking, though no studies have yet addressed this possibility. Utilizing data from a large sample of graduating college students during senior year and the two following years (N = 907), the current study examined relations between aspects of emerging adult identity development (identity exploration, instability, self-focus, feeling in-between, and experimentation/possibilities) and drinking outcomes (alcohol use and problems). Using multiple regression, changes in emerging adult identity development accounted for significant variability in alcohol use over and above relationship and employment status. Decreases in experimentation/possibilities significantly predicted decreases in alcohol use. Conversely, increases in feeling in-between significantly predicted decreases in alcohol use. The findings have important implications for both theories of "maturing out" and the development of prevention and early intervention efforts targeting alcohol abuse during this high-risk developmental period.
