Cognitive control processes underlying continuous and transient monitoring processes in event-based prospective memory

A converging operations approach using response time distribution modeling was adopted to better characterize the cognitive control dynamics underlying ongoing task cost and cue detection in event based prospective memory (PM). In Experiment 1, individual differences analyses revealed that working memory capacity uniquely predicted nonfocal cue detection, while proactive control and inhibition predicted variation in ongoing task cost of the ex-Gaussian parameter associated with continuous monitoring strategies (mu). In Experiments 2A and 2B, quasi-experimental techniques aimed at identifying the role of proactive control abilities in PM monitoring and cue detection suggested that low ability participants may have PM deficits during demanding tasks due to inefficient monitoring strategies, but that emphasizing importance of the intention can increase reliance on more efficacious monitoring strategies that boosts performance (Experiment 2A). Furthermore, high proactive control ability participants are able to efficiently regulate their monitoring strategies under scenarios that do not require costly monitoring for successful cue detection (Experiment 2B). In Experiments 3A and 3B, it was found that proactive control benefited cue detection in interference-rich environments, but the neural correlates of cue detection or intention execution did not differ when engaged in proactive versus reactive control. The results from the current set of studies highlight the importance of response time distribution modeling in understanding PM cost. Additionally, these results have important implications for extant theories of PM and have considerable applied ramifications concerning the cognitive control processes that should be targeted to improve PM abilities.

The cognitive underpinnings of multiply-constrained problem solving

Description
In the daily life of an individual problems of varying difficulty are encountered.

solver. One type of problem commonly used in research are multiply-constrained

In the daily life of an individual problems of varying difficulty are encountered.

Each problem may include a different number of constraints placed upon the problem

solver. One type of problem commonly used in research are multiply-constrained

problems, such as the compound remote associates. Since their development they have

been related to creativity and insight. Moreover, research has been conducted to

determine the cognitive abilities underlying problem solving abilities. We sought to fully

evaluate the range of cognitive abilities (i.e., working memory, episodic and semantic

memory, and fluid and crystallized intelligence) linked to multiply-constrained problem

solving. Additionally, we sought to determine whether problem solving ability and

strategies (analytical or insightful) were task specific or domain general through the use

of novel problem solving tasks (TriBond and Location Bond). Results indicated that

multiply-constrained problem solving abilities were domain general, solutions derived

through insightful strategies were more often correct than analytical, and crystallized

intelligence was the only cognitive ability that provided unique predictive value.

The purpose of this study was to develop proposal lesson plans for 4th-6th graders based on active learning to integrate movement physical activity into the curriculum. The 4th-6th graders were chosen, as this is the age where teaching typically transitions from active learning to sedentary/lecture style teaching. Research compiled indicated positive effects of active based learning on children such as increased attention span, retention, and general focus. A survey was created to not only assess the perception of active versus didactic learners, but to also assess the effects of movement-based learning on the variables that research claimed to change. The lesson plans developed here should be transferable to a classroom lesson to evaluate the hypothesized results.

The relevance of depression in the clinical realm is well known, as it is one of the most common mental disorders in the United States. Clinical depression is the leading cause of disease for women worldwide. The sex difference in depression and anxiety has guided the research of not just recent studies but older studies as well, supporting the theory that gonadal hormones are associated with the mechanisms of emotional cognition. The scientific literature points towards a clear correlative relationship between gonadal hormones, especially estrogens, and emotion regulation. This thesis investigates the neural pathways that have been indicated to regulate mood and anxiety. Currently, the research points to the hypothalamic-pituitary-adrenal axis, which regulates the stress response through its ultimate secretion of cortisol through the adrenal cortex, and its modulated response when exposed to higher levels of estrogen. Another mechanism that has been investigated is the interaction of estrogen and the serotonergic system, which is noteworthy because the serotonergic system is known for its importance in mood regulation. However, it is important to note that the research seeking to determine the neurobiological underpinnings of estrogen and the serotonergic system is not expansive. Future research should focus on determining the direct relationship between cortisol hypersecretion and estrogens, the specific neurobiological effects of serotonergic receptor subtypes on the antidepressant actions of estrogens, and the simultaneous effects of the stress and serotonergic systems on depressive symptoms.

Previous research has determined that sentence comprehension is affected when taxing an individual’s cognitive resources, such as attentional control and working memory. This can be done by manipulating the prosody of simple and complex sentences, by allowing irregular rhythm and pitch changes to occur within speech. In the present thesis, neurotypical adults were asked to comprehend sentences with normal and monotone prosody in three different versions of a sentence-picture matching task. A no-load version served as a control with the other two taxing cognitive resources in these individuals. In addition, individuals completed four other tasks that are known to reliably measure working memory. Our results indicate a possible relationship between high accuracy in complex sentences spoken in a monotone prosody with working memory when time restraints are placed on individuals. Collectively, these results may lead to a new way of working with individuals in speech therapy who have suffered a stroke by better understanding the cognitive resources that are taxed in different types of sentence comprehension settings.
