Reading Between the Lines: The Potential of Popular Young Adult Fiction in Adolescent Spiritual Formation

Popular culture is a powerful, shaping force in the lives of teenagers between the ages of fourteen through eighteen in the United States today. This dissertation argues the importance of popular fiction for adolescent spiritual formation and it investigates that importance by exploring the significance of narrative for theology and moral formation. The dissertation employs mythic and archetypal criticism as a tool for informing the selection and critique of narratives for use in adolescent spiritual development and it also incorporates insights gained from developmental psychology to lay the groundwork for the development of a curriculum that uses young adult fiction in a program of spiritual formation for teenagers in a local church setting. The dissertation defends the power of narrative in Christian theology and concludes that narrative shapes the imagination in ways that alter perception and are important for the faith life of teenagers in particular. I go on to argue that not all narratives are created equal. In using literary myth criticism in concert with theology, I use the two disciplines’ different aims and methods to fully flesh out the potential of theologies intrinsic to works meant for a largely secular audience. The dissertation compares various works of young adult fiction (M.T. Anderson’s Feed and Terry Pratchett’s Nation in dialogue with a theology of creation; Marcus Zusak’s I am the Messenger and Jerry Spinelli’s Stargirl in dialogue with salvation and saviors; and the four novels of Stephanie Meyer’s Twilight saga in dialogue with a theology of hope (eschatology). The dissertation explores how each theme surfaces (even if only implicitly) from both literary and theological standpoints. The dissertation concludes with a sample four-week lesson plan that demonstrates one way the theological and literary critique can be formed into a practical curriculum for use in an adolescent spiritual development setting. Ultimately, this dissertation provides a framework for how practitioners of young adult formation can select, analyze, and develop materials for their teenagers using new works of popular young adult fiction. The dissertation comes to the conclusion that popular fiction contains a wealth of material that can challenge and shape young readers’ own emerging theology.

The Hippocampus and Cerebellum in Adaptively Timed Learning, Recognition, and Movement

The concepts of declarative memory and procedural memory have been used to distinguish two basic types of learning. A neural network model suggests how such memory processes work together as recognition learning, reinforcement learning, and sensory-motor learning take place during adaptive behaviors. To coordinate these processes, the hippocampal formation and cerebellum each contain circuits that learn to adaptively time their outputs. Within the model, hippocampal timing helps to maintain attention on motivationally salient goal objects during variable task-related delays, and cerebellar timing controls the release of conditioned responses. This property is part of the model's description of how cognitive-emotional interactions focus attention on motivationally valued cues, and how this process breaks down due to hippocampal ablation. The model suggests that the hippocampal mechanisms that help to rapidly draw attention to salient cues could prematurely release motor commands were not the release of these commands adaptively timed by the cerebellum. The model hippocampal system modulates cortical recognition learning without actually encoding the representational information that the cortex encodes. These properties avoid the difficulties faced by several models that propose a direct hippocampal role in recognition learning. Learning within the model hippocampal system controls adaptive timing and spatial orientation. Model properties hereby clarify how hippocampal ablations cause amnesic symptoms and difficulties with tasks which combine task delays, novelty detection, and attention towards goal objects amid distractions. When these model recognition, reinforcement, sensory-motor, and timing processes work together, they suggest how the brain can accomplish conditioning of multiple sensory events to delayed rewards, as during serial compound conditioning.

Space, Time and Learning in the Hippocampus: How Fine Spatial and Temporal Scales Are Expanded into Population Codes for Behavioral Control

The hippocampus participates in multiple functions, including spatial navigation, adaptive timing, and declarative (notably, episodic) memory. How does it carry out these particular functions? The present article proposes that hippocampal spatial and temporal processing are carried out by parallel circuits within entorhinal cortex, dentate gyrus, and CA3 that are variations of the same circuit design. In particular, interactions between these brain regions transform fine spatial and temporal scales into population codes that are capable of representing the much larger spatial and temporal scales that are needed to control adaptive behaviors. Previous models of adaptively timed learning propose how a spectrum of cells tuned to brief but different delays are combined and modulated by learning to create a population code for controlling goal-oriented behaviors that span hundreds of milliseconds or even seconds. Here it is proposed how projections from entorhinal grid cells can undergo a similar learning process to create hippocampal place cells that can cover a space of many meters that are needed to control navigational behaviors. The suggested homology between spatial and temporal processing may clarify how spatial and temporal information may be integrated into an episodic memory.
