Infants' Understanding of Goal Directed Behavior
As adults, we interpret the actions of others as directed towards goals and we use that goal information to help make sense of others' actions. Infants as young as 5 months of age understand some of the repeated actions of others as directed toward the goal of obtaining a specific object (Woodward, …

How Want vs Need Self-Talk Facilitates Goal-Directed Behavior
… temptations or striving toward long-term goals. When attempting to exert self-control, the way people address themselves (e.g., self-talk) is important. This study examined how self-talk strategies want and need affected behavioral self-control outcomes in a temptation situation using a 2 …

Age-dependent effects of chronic amphetamine on prelimbic-nucleus accumbens circuit function and goal-directed behavior
… abnormalities in the reward circuit function and goal-directed behavior. Using a rat model, this hypothesis was tested with three specific aims: (1) to investigate the ontogeny of this LTD function (Experiment 1), (2) to assess the effect of adolescent and adult amphetamine on HFS-induced LTD in …

CELLULAR CODING PROPERTIES OF GOAL DIRECTED BEHAVIOR IN THE MEDIODORSAL AND INTRALAMINAR NUCLEUS OF THE RAT: COMPARISONS TO PREFRONTAL CORTEX
… (PFC) through multiple pathways to control goal directed behavior. The initial purpose of this dissertation was to characterize cellular coding properties of these nuclei in central thalamus using electrophysiological measures in awake, behaving rats performing a dynamic delayed non-match to …

Habit Formation in a Rodent Model of Alcoholism: Genetic Susceptibility, Alcohol-Specific Effects, and Pharmacological Manipulation
… It is hypothesized that a transition from goal-directed behavior to habitual behavior is driven by a transition of the bulk of cognitive load from neocortical toward lower neurological mechanisms. While many neurotransmitter systems have a demonstrated involvement in this process, the …

Consumer Streaks
… consumers can record and track their behaviors more easily than ever before. Consequently, consumers are now especially aware of their streaks (i.e., doing something three or more times in a row) and other patterns of behavior. In my dissertation, I explore how patterns of repeated …

Multiplexed representations of uncertainty by mouse pulvinar-prefrontal projections during goal-directed behaviors
… and action is a central component of learned, goal-directed behavior. Even during ongoing sensory-motor processing, our sensory landscape is fltered through our prior expectations and ongoing goals. This active perceptual process hinges on a distributed network of cortical and subcortical …

Neural correlates of locomotion, cues, and context in the interactions between hippocampus and lateral septum
… the hippocampus (HPC) and regions that mediate goal directed behavior. In this study, we simultaneously record from cells in the LS and the HPC during navigation and conditioning tasks. We identify a speed and acceleration spiking code in the LS that does not map to states of motivation or …

Investigating the relationship between intelligence and executive function through visual scanning strategies
… processes responsible for higher-order thinking, behavioral regulation, and goal-directed behavior, while intelligence is considered a contributing factor to cognitive performance. Previous research has explored the relationship between these two constructs, but it has potentially overlooked the …

Life moves on: An exploration of motivation in elderly women
… models, however, would not identify these behaviors as achievement. An alternative model of person/environmental interaction is drawn from developmental, motivational, and environmental perspectives and provides a conceptual handle for grasping the dynamics of goal-directed behavior. When …

Learning structured representations for perception and control
… towards building agents that learn to produce goal-directed behavior given sensations. I present models and algorithms that learn from raw observations and will emphasize on minimizing their sample complexity and number of training steps required for convergence. To this end, I introduce …

Neural dynamics supporting flexible cognition
… cognition enables humans to adapt their behavior to changing circumstances by prioritizing relevant information and filtering out distractions. This process is thought to be supported by the integration of ongoing behavioral goals with incoming sensory information, but how this …

A functional MRI study of the distributed neural circuitry of learning and reward
… of reward is one of the fundamental aspects of goal directed behavior, and studies have shown that this process involves the midbrain dopamine system. Work by C. R. Gallistel has shown that the reward magnitude of electrical stimulation to structures within this system increases with increasing …

ATTENTION TRAINING AND MINDFULNESS AS INTERVENTIONS FOR RUMINATION: ASSOCIATIONS WITH COGNITIVE CONTROL
… to higher order cognitive processes used for goal-directed behavior, including emotion regulation. The current study examined associations between the switching component of cognitive control and rumination and tested the effects of two interventions used to improve cognitive control and …

Hierarchical reasoning in the brain
… at multiple spatiotemporal scales to guide our goal-directed behavior. Understanding the neural mechanism of this reasoning behavior is essential for consequential applications in brain sciences. In this thesis, I address hierarchical reasoning at three levels of behavior, neural circuit, and …

The Influence of Money on Goal Pursuit and Decision-Making: Understanding Money's Unique Impact on Goal Pursuit
… can increase motivation to achieve personal goals. In this dissertation, I investigate how money affects pursuit of important personal goals, and how this motivation may be affected by goal attainability. In eight studies, I show that priming concepts of money and wealth leads individuals to …

From Terrible Twos to Sassy Sixes: The Development of Vocabulary and Executive Functioning Across Early Childhood
… processes that underlie self-modulated and goal-directed behavior (i.e., executive functions (EF)). Although there is empirical evidence to support the association between EF and vocabulary development in childhood, inconsistent findings have been reported regarding the extent to which early …

The Cognitive and Neural Basis for Apathy in Frontotemporal Degeneration
The syndrome of apathy, defined as a reduction in goal-directed behavior (GDB), has profound consequences for morbidity and mortality in the patient and for family-caregiver burden. Apathy is one of the primary neuropsychiatric syndromes associated with the disruption of the frontal-striatal …
