Description
Recent evidence suggests that youth from affluent and upper-middle-class, white collar families are at high risk for maladaptive behaviors, such as aggression, rule breaking, and substance use. A major hypothesized underlying factor is lax parental discipline that involves low repercussions for errant behaviors such as substance use—also known as perceived parents’ “containment” of such behaviors. In this study, the focus is on multiple dimensions of perceived containment among parents and school authorities, in relation to both externalizing problems and drug use behaviors. These associations are examined in four different schools: two boarding schools and two day schools. Results show much stronger links with maladjustment for perceived containment by parents as opposed to perceived containment by school. The largest significant effects within the containment indices were found to be between parent containment of drug use and the levels of substance use behaviors reported by students. These effects were found across gender and all schools, indicating robust links. Overall, the most robust index studied was the perceived parental monitoring variables; monitoring effects were stronger than effects from any containment variables. Students who perceived the highest levels of parental monitoring exhibited the least amount of externalizing behaviors across all schools and genders. A possible explanation includes students perceiving that their parents monitor their behavior due to caring on the behalf of the parent, which then leads to fewer externalizing outcomes. These results suggest that the most effective means of decreasing substance use levels seem to lie within the parents of the students and not the schools.

Description
Simulation theory states that text comprehension is achieved by simulating (or imagining) text content using motor, perceptual, and emotional systems. Hence, motor skill should correlate with comprehension skill. In fact, previous research has linked fine motor skills (FMS) with word processing and mathematical skills. I predicted a positive relationship between FMS and reading comprehension. Children enrolled in a reading comprehension intervention were assessed on FMS using the Movement ABC-2. There was a significant correlation between FMS and comprehension of narrative texts, but contrary to the prediction, the correlation was negative. Also unexpected, the control condition performed better on comprehension questions than the intervention conditions. To try to understand these results, we examined the time each child took to answer the comprehension questions. Many children answered the questions quickly, and average time to answer the questions was strongly correlated with comprehension scores. Children may have been answering questions quickly (and randomly) in order to advance to the next story. Nonetheless, the data do not support a relationship between FMS and reading comprehension.

Description
Introduction: Depression is one of the most prevalent mental illnesses in the United States, and is characterized by feeling sad or empty most of the day, nearly every day (American Psychiatric Association, 2013). The experience of childhood trauma is one of many factors that may lead to depression, while trauma can also yield other adverse life outcomes, such as alcohol-related consequences (Felitti et al., 2001; Neumann, 2017). One of the specific aims of this investigation was to examine the direct influences of childhood trauma on depression. We also examined selected direct and indirect influences of childhood trauma on drinking outcomes through the potential mediating mechanism of depression. We examined three distinct drinking outcomes, 1) impaired control over drinking (i.e. the inability to stop drinking when intended), 2) heavy episodic drinking (four or more drinks on one occasion for men, four or more for women), and 3) alcohol-related problems. Methods: A survey was administered to 940 (466 women, 474 men) university students. Structural equation modeling was used to examine the data. Potential two- and three-path mediated effects were examined with the bias corrected bootstrap technique in Mplus (MacKinnon, 2008). Results: Emotional abuse was found to be positively associated with depression. In contrast, having an emotionally supportive family was found to be negatively associated with depression. Congruent with the Self-Medication Hypothesis, depression was found to be positively associated with impaired control over drinking. Physical neglect was found to be positively associated with impaired control. Lastly, emotional abuse was found to be indirectly linked to increased heavy episodic drinking and alcohol-related problems through depression and impaired control.

Description
Fast mapping is the initial link infants make between a word and its referent, and it is crucial to later processes of learning the meanings of words. Despite the importance of fast mapping, previous research has suggested that fast mapping is fragile, with infants being unable to retain words learned through fast mapping longer than five minutes. The current study tested the robustness of fast mapping by imposing task irrelevant interruptions on a fast mapping task. Forty-seven infants (14.7 \u2014 17.4 months old) were assigned to a No Interruption condition, a Posture Interruption condition, or a Visual Interruption condition, and they performed a fast mapping task in which a novel object was named in one trial. Videos of the infants were coded for accuracy of fast mapping and for attentional behaviors (looking behavior) during the task. We found that infants did not learn novel word-object pairings when interrupted, demonstrating that infants' fast mapping abilities are easily disrupted. Overall, there was no evidence that looking behaviors were affected by interruptions, or that they were correlated with accuracy. These findings suggest that fast mapping is fragile in young infants, and further research is required to determine the mechanisms for infant learning, and how infants transition from fast to slow mapping processes.

Description
A recent controversy has surrounded service dogs in public environments. Use of service dogs may trigger discrimination against individuals with non-visible disabilities. Major goals of this thesis study are to examine if significant differences exist in personality perceptions and attitude towards service dog owners with visible disabilities versus those with non-visible disabilities, and whether these perceptions and attitude predict how they would be treated in a public setting. The study employed a mixed 2 x2 factorial experiment design. The first independent variable was visibility of the disability, with the two levels being visible vs non-visible, and this factor was non-repeated in nature. The second independent variable was the target of evaluation, with the owner and the dog being the two levels, and this was a repeated measure. Specifically, this study assessed personality perceptions using the Big Five personality traits (Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to Experience) and operationalized attitude in terms of the positivity of personality perceptions. Additionally, this study examined whether an owner of a service dog with a non-visible disability would be treated differently from their counterpart who has a visible disability. In the study, participants were given a scenario and picture where they encounter an individual who either had a visible or non-visible disability with a service dog at a restaurant. Then, participants rated the owner and the dog individually on the Big Five personality traits, and indicated whether and how likely they would seat the individual and their service dog at the restaurant. When considering the visibility of a disability alone, an individual with a non-visible disability was perceived as less conscientious. When considering how the owner and the dog were perceived regardless of visibility of disability, owners were rated significantly lower than their dog on agreeableness and extraversion, but significantly higher on openness to experience. There was also a significant difference in treatment of the dog owners based on the visibility of their disability, service dog owners with non-visible disabilities have a higher likelihood of experiencing unlawful treatment. Furthermore, personality perceptions and attitude were significantly correlated with treatment for both individuals with non-visible and visible disabilities. Together, findings of this study inform the design of future research. Future research on this topic may help inform policy makers the challenges and unfair treatment facing individuals who have non-visible disabilities.

Description
Previous research pertaining to dog memory and cognition has been confined mainly to samples of colony dogs and therefore can be hard to generalize to a larger population of pet dogs and varying breeds. The present study focused entirely on pet dogs of many different breeds, rather than colony or laboratory animals for the purposes of accessibility, affordability, and novelty. Methods: We presented the dogs with a memory task in the form of a game in which the dogs chose to search for food at one of two locations at varying delay intervals, with a maximum time limit of one hour per dog. We expected our data to show a significant decrease in memory capacity and an increase in error rates among older dogs as compared to younger dogs; these results would allow us to conclude that it is likely many dogs, much like humans, experience various cognitive deficits as a function of increasing age. Results: Using one-factor ANOVA and linear and curvilinear regression analyses, we examined the relationship between the independent variable, age (individual dog ages as well as three generalized age categories), and three dependent variables. The dependent variables were: (a) percentage of correct choices at a 60 second delay interval, (b) maximum delay interval attempted (MDIA), and (c) the maximum delay interval that was completed above chance level (50%) (MDAC). We found significant results to support our hypotheses that aged dogs show spatial memory and cognitive deficits in comparison with young and middle-aged dogs, and that age can be considered a marginally significant predictor of spatial memory capacity.

Description
The purposes of the study are to: 1) investigate how students' motivation towards reading is related to their reading comprehension skills, and 2) assess the impact of using an Intelligent Tutoring System to improve comprehension. Interactive Strategy Training for Active Reading and Thinking-3 (iSTART-3) is a game-based tutoring system designed to improve students' reading comprehension skills. The current study was conducted in South Africa with 8th and 9th graders between the ages of 14 and 18. These students are multilingual and they learn English as a First Additional Language (English-FAL). Firstly, we predict that students who are highly motivated to read will have high comprehension scores than those who are slightly or not at all motivated to read. Secondly, we predict that the use of iSTART-3 will improve students' reading comprehension, regardless of their level of reading motivation, with better results for those who are more motivated to read. Counter to our predictions, the results did not reveal a relation between reading motivation and reading comprehension. Furthermore, an effect of iSTART-3 on reading comprehension was not found. These results were likely influenced by the small sample size and the length of the intervention.

Description
The aim of this study was to determine whether IUD administration, with and without the presence of Levo, and with and without the presence of the ovaries, impacts cognition in a rat model. Rats received either Sham or Ovariectomy (Ovx) surgery (removal of the ovaries), plus either no IUD, a Blank IUD (without Levo), or a Levo-releasing IUD (Levo IUD), enabling us to evaluate the effects of Ovx and the effects of IUD administration on cognition. Two weeks after surgery, all treatment groups were tested on the water radial arm maze, Morris water maze, and visible platform task to evaluate cognition. At sacrifice, upon investigation of the uteri, it was determined that some of the IUDs were no longer present in animals from these groups: Sham\u2014Blank IUD, Ovx\u2014Blank IUD, and Sham\u2014Levo IUD. Results from the remaining three groups showed that compared to Sham animals with no IUDs, Ovx animals with no IUDs had marginally impaired working memory performance, and that Ovx animals with Levo IUDs as compared to Ovx animals with no IUDs had marginally enhanced memory performance, not specific to a particular memory type. Results also showed that Ovx animals with Levo IUDs had qualitatively more cells in their vaginal smears and increased uterine horn weight compared to Ovx animals with no IUDs, suggesting local stimulation of the Levo IUDs to the uterine horns. Overall, these results provide alternative evidence to the hypothesis that the Levo IUD administers Levo in solely a localized manner, and suggests that the possibility for the Levo IUD to affect reproductive cyclicity in ovary-intact animals is not rejected. The potential for the Levo IUD to exert effects on cognition suggests that either the hormone does in fact systemically circulate, or that the Levo IUD administration affects cognition by altering an as yet undetermined hormonal or other feedback between the uterus and the brain.

Description
Teacher assessments are often used alongside parent assessments to identify behavioral problems and patterns in school-aged children. These assessments can aid in the diagnosis of disruptive behavior disorders and are used to screen children for targeted delinquency prevention programs. Although researchers have heavily studied the relationship between parent and teacher assessments, not as much research has analyzed teacher assessments alone, specifically semiannual teacher assessments. Teacher assessments are typically conducted during the fall semester, normally a couple months into the school year, or during the spring semester, normally a couple months after the winter break period. Using data from the Pittsburgh Youth Study (PYS), we aimed to determine the temporal stability and predictive utility of semiannual teacher assessments of children's behavioral problems from 2nd grade to 5th grade. Results showed that mean assessment scores increased from the fall to the spring semester across all 4 grades. We also found that teacher assessments of behavioral problems in grade school were significantly correlated with future serious violence. Although our statistical model did not identify a specific time period or semester when these assessments were most predictive, we observed a pattern where the spring semesters were more predictive for the younger grades, and the fall semesters were more predictive for the older grades. Future research could aim to understand why this pattern exists and what its implications are.

Description
BACKGROUND: Delirium is often not recognized by clinicians at hospice facilities, leading to the lack of beneficial interventions. The aim of this study is to find a baseline of how many patients show signs of delirium, dementia, or both, determine whether clinicians are recognizing these signs, and observe how dementia and delirium are being treated for these patients.
DESIGN: Patient charts were reviewed to obtain demographic information, medications, and patients' progress throughout stay including pharmacologic and non-pharmacologic interventions and results. Patients were then interviewed using the short portable mental status questionnaire.
SETTING: The prevalence and management of dementia and delirium was evaluated in 10 Hospice of the Valley inpatient settings.
RESULTS: Out of the 159 participants (mean age = 77.72 years), 93 (58.5%) presented with moderate to severe cognitive impairment, but only 38 participants (23.9%) had a formal diagnosis of dementia. Out of the 93 participants with significant cognitive impairment, 60 participants (65.6%) were treated with benzodiazepines and 82 (88.2%) were treated with opioids. Fifty-nine (63.4%) participants with cognitive impairment had documented non pharmacological interventions such as repositioning and reorientation, but only 22 (23.7%) participants received more meaningful non-pharmacological interventions such as hand massages, targeted videos, and favorite music.
CONCLUSIONS: The current study found a high prevalence of moderate to severe cognitive impairment without a diagnosis of dementia. A likely cause is the high frequency of opioids and benzodiazepines prescribed, causing drug-induced sedation and delirium which significantly impairs cognitive abilities. Safer alternatives, such as non-opioid pain medications, should be considered within the hospice population, especially given that age is a risk factor for delirium. A tool would be helpful to encourage staff to identify and document use of non-pharmacological interventions.
