In everyday life, mental fatigue can be detrimental across many domains including driving, learning, and working. Given the importance of understanding and accounting for the deleterious effects of mental fatigue on behavior, a growing body of literature has studied the role of executive control processes in mental fatigue. In a laboratory setup, participants complete a task that places demands on executive control processes and are later given a transfer task. Generally speaking, decrements to subsequent task performance are taken as evidence that the initial executive control task created mental fatigue through the continued engagement of executive control. Several hypotheses have been developed to account for negative transfer resulting from executive control depletion including cognitive resource depletion and task-switching. In the current study, we provide a brief literature review, specify current theoretical approaches to depletion, and provide a strong empirical test of theories for negative transfer from executive control depletion (i.e., does continued performance of an executive control task negatively transfer to that exact same task).

While the concept of healthcare is largely respected in Arab culture, the stigma underlying mental health is particularly startling. This study examined the differences in mental health treatment-seeking behaviors using data from Arabs living in Syria (12.9%) and Arabs (25.6%) and non-Arabs (61.5%) living in the United States of ages 18-60. A Web-based survey was developed to understand how factors like religiosity, acculturation, and positive attitudes towards psychological treatment increased help-seeking behaviors. This survey was also provided in Arabic to include non-English speaking participants. It was hypothesized that Arab-American individuals will be more open to pursuing professional psychological help when suffering from mental symptomology (i.e. anxiety) than individuals who identified as Syrian-Arabs. In contrast, both Syrian-Arabs and Arab-Americans would definitely pursue professional help when suffering from physical symptomology (i.e. ankle sprain). Striking differences were found based on Western acculturation. Findings suggested that Arab-Americans were less inclined towards treatment and more trusting of an in-group physician ("Dr. Ahmed") whereas Syrian-Arabs were more inclined to pursue psychological treatment and preferred to trust an out-group physician ("Dr. Smith"). The results of this study identify main concerns regarding Arab attitudes towards seeking mental health treatment, which can better inform future research and mental health services for this minority.

Intrauterine devices (IUDs) have become one of the most common types of contraception in the United States. In the last decade, the American College of Obstetricians and Gynecologists, the World Health Organization, and the Food and Drug Administration (FDA) updated IUD recommendations to include placement in younger populations and nulliparous women. Research has shown that younger, nulliparous women may have smaller uterine dimensions and it is possible that larger IUDs are not suitable for those populations. This study retrospectively evaluated follow-up pelvic ultrasounds showing uterine dimensions and IUD positions of 57 women who had IUDs placed in a clinic. The largest IUD, the Paragard, showed a significantly higher rate of malpositioning than the Kyleena, Liletta, and Mirena IUDs. There is concern that the Paragard IUD, which is most commonly malpositioned, is also the IUD most dependent on position for adequate contraception. There was no correlation between uterine dimensions and IUD position at the time of analysis, however. Further data collection will continue in hopes that a larger sample size will reveal a parameter which affects IUD placement. Should further data analysis show that uterine width plays an important role in IUD position, the design for a device which can measure the width of patient's uterus (without the need for pelvic ultrasound) has been included. The concept generation for this measurement device includes laser measurements of uterine cavity width at different known lengths from the fundal wall, which output to an LED screen for recording.

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.

This study examined the relation between Religiosity (a motivational system) and Working Memory Capacity (a cognitive system) to determine how they interact to promote goal-directed behavior. Participants completed a religiosity questionnaire and engaged in a battery of tasks that were used to assess their Working Memory Capacity (WMC) and overall ability to maintain goal-directed behavior. The Stroop task was used to examine the participants' ability to maintain goals in the face of interference. It was predicted that religiosity and WMC would be inversely related and that when we controlled for religiosity, WMC would be the only significant predictor of Stroop performance. Furthermore, we hypothesized that religiosity and Stoop would be inversely related, whereas WMC and Stroop would be positively correlated with one another. Religiosity and Stroop performance were each divided into three different components. Religiosity was divided into: Intrinsic Motivation, Extrinsic Motivation, and CARMA. Stroop Performance was measured through Stroop Accuracy, the Stroop Effect, and Post-Error Slowing. The results of our study supported each of our hypotheses. These findings demonstrated that there is a cognitive process underlying motivational systems, such as religion, which affect an individual's ability to sustain goal-directed behavior.

Problem solving is a crucial skill needed to accomplish everyday tasks and overcome potential obstacles. One way to measure individual differences in problem solving ability is through performance differences on multiply-constrained problem solving tasks. Multiple cognitive processes are involved in multiply-constrained problem solving. An individual uses prospective metacognitive monitoring judgments to gauge future allocation of resources before engaging in the necessary semantic search. Problem solvers also vary in their semantic search strategies, and use either an active analytical strategy or a passive insight strategy to arrive at asolution. Prospective metacognitive monitoring judgments and solution strategies are two aspects of the problem solving process that occur at specific points in the process while motivation influences problem solving throughout the process. The goal of this study is to examine prospective metacognitive judgments, problem solving accuracy, solution strategy, and motivation in multiply-constrained problem solving. Motivation was manipulated using a performance based monetary incentive. Participants self reported prospective Feeling-of-Knowing judgments after brief exposure to the problem, and solution strategy ratings after each problem. No significant differences were found to support the effect of motivation on problem solving accuracy, prospective metacognitive judgments, relative accuracy, or solution strategies. Significant differences were found between groups when comparing the number of problems skipped, indicating that participants were sensitive to the incentive structure. The findings suggest that motivation may not be an overarching mediator in multiply-constrained problem solving or problem solving may require a specific type of incentive structure to increase accuracy. However, little is known in the research literature about the type of incentive structure needed to consistently increase individual motivation.

In everyday life, unfocused attention can be detrimental to life either through driving vehicles, cutting vegetables, and learning new languages. In order to increase sustained attention, Binaural Beats were introduced. Binaural Beats have two different frequency tones which oscillate to produce different effects. Each of these beats operates at different frequencies thus having different sound production: theta, delta, alpha, beta, and gamma. In the experiment beta Binaural Beats with frequencies of 200 and 216 Hertz, Hz (unit of measurement for frequency), were used with a control of 200 Hz flat noise. The experiment utilized the psychomotor vigilance task to measure changes in response times and utilized Affectiva to measure changes in facial musculature. The response times were then analyzed to explain why the Binaural Beats condition had significantly shorter response times compared to the control group throughout the task. In terms of emotional change, some trends were noticed for the Binaural Beats and the control condition; however, none of the trends were significant. Moving forward with the experiment, an increased number of participants can be recorded to strengthen the validity and test different frequencies of Binaural Beats for accuracy.

The period of time between birth and 24 months of age is a sensitive period for infant growth, and adequate nutrition is vitally important. In this study, 150 Mexican-American mother-and-child pairs (N = 300) were periodically surveyed over the course of 36 months for demographics, financial status, and feeding practices to understand the feeding methods of Mexican-American families and any relations they may have to the weight and growth of developing infants. Results found that formula feeding had higher rates of usage and duration than breastfeeding, while solid foods were largely introduced at the recommended ages. At one year of age, the infants were predisposed towards overweight and obesity with a high maternal BMI, suggesting that breastfeeding practices were not fully utilized. However, the data did not differentiate between formula and breast milk when both were used at any specific age, making it difficult to determine how long infants were exclusively breastfed and how that would impact their growth.

Recognition memory is examined by exposing a person to a stimulus and later prompting them with the same stimulus to examine their ability to accurately acknowledge that the stimulus was previously encountered (Kahana, 2012). In recognition memory, confidence ratings are taken during the testing phase to assess how confident the participant is that the old-new judgment that they just made is accurate (Busey et al., 2000). Confidence is a metacognitive assessment about the accuracy of perception of decision making based on the amount, speed, and clarity of thoughts that come to mind (Dunlosky and Metcalfe, 2008). The goal of the current study is to better understand how assessing recognition memory using a variety of test procedures influences memory accuracy using the signal detection theory and adding multiple confidence scales that vary in granularity. Based on the previous literature, it is hypothesized that; 1) tasks ordered sequentially will produce greater recognition accuracy (d') than the simultaneous (dual task) condition; 2) confidence scale of 3 points will produce a larger d' than the 7 point scale, and the 7 point scale will produce a larger d' than the 100 point scale; and 3) task mode (ordered vs. sequenced) will interact with confidence scale granularity to predict memory accuracy, such that sequential judgments lessen demands on working memory that come from maintaining an increasing number of decision criteria in comparison to the dual task. Results indicated all hypotheses were not upheld. The findings suggest that taxing working memory may not affect decisional accuracy on a recognition task incorporating confidence judgments.

This longitudinal research study addresses the correlations between infant feeding status in relation to infant temperament, maternal postpartum depression, and weight changes over time in a lower income, diverse population sample. The majority of participants were enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Mesa, Arizona. Each participant was recruited in their third trimester and followed for the infants' first six months of life. A series of four home visits were made in which demographic surveys, temperament questionnaires, postpartum depression scales, weight changes over time, fecal, vaginal, saliva, and breast milk samples were taken. Due to the extensive process of extracting and sequencing of the microbiome samples, data has yet to be collected from the fecal, vaginal, saliva, and breast milk samples and were not included in this study. Correlational and descriptive statistics were run on the qualitative data including various demographic questions, total temperament, depression, and healthy eating index scores. It was found that lower socioeconomic factors contributed to more difficult infant temperaments, mothers who breastfed had higher post-delivery postpartum depression scores, and mothers with healthier eating indexes formula or mixed fed their infants. The findings from this data will be compared to the incoming microbiome data to examine the role of the microbiome of mothers and infants and its effects on infant temperament, postpartum depression, and weight changes over time.
