Context, Goals, And Operant Behavior: The Role Of The Prelimbic Cortex And Associated Neural Circuitry, Callum Mark Piper Thomas

Graduate College Dissertations and Theses

Operant (instrumental) conditioning is a laboratory model of voluntary behavior. In its simplest form, performing a particular response, such as a lever press, leads to delivery of a reinforcing outcome (e.g., a sucrose pellet). Operant behaviors can be associated with preceding stimuli (“habits”) or outcomes (“goal-directed actions”). A factor that influences performance of operant behaviors is the context in which they are learned. Contexts can be defined as background stimuli that are present during behavior. For example, eating dessert may occur in the context of a restaurant and the sated feeling of a finished meal. The context for eating dessert, …

How And Why Do People Value Nature? An Examination Of Nonmaterial Aspects Of Human-Nature Interactions., Tatiana Marquina

Graduate College Dissertations and Theses

Nonmaterial benefits from nature, often labeled as cultural ecosystem services, represent a core dimension of human well-being. Yet despite their importance, these benefits and associated values remain overlooked in environmental assessments and decisions.

This dissertation applies insights from multiple disciplines to document nonmaterial dimensions of human-nature interactions across geographic contexts and user groups. As nonmaterial benefits can be hard to elicit and measure, this work uses multiple existing data collection methods and tests a novel data collection tool. First, I use a qualitative study design to explore values and stewardship practices associated with urban foraging in New York City, NY. …
