Representation, space and Hollywood Squares: Looking at things that aren't there anymore
It has been argued that the human cognitive system is capable of using spatial indexes or oculomotor coordinates to relieve working memory load (Ballard, Hayhoe, Pook & Rao, 1997) track multiple moving items through occlusion (Scholl & Pylyshyn, 1999) or link incompatible cognitive and sensorimotor codes (Bridgeman and Huemer, 1998). Here we examine the use of such spatial information in memory for semantic information. Previous research has often focused on the role of task demands and the level of automaticity in the encoding of spatial location in memory tasks. We present five experiments where location is irrelevant to the task, and participants' encoding of spatial information is measured implicitly by their looking behavior during recall. In a paradigm developed from Spivey and Geng (submitted), participants were presented with pieces of auditory, semantic information as part of an event occurring in one of four regions of a computer screen. In front of a blank grid, they were asked a question relating to one of those facts. Under certain conditions it was found that during the question period participants made significantly more saccades to the empty region of space where the semantic information had been previously presented. Our findings are discussed in relation to previous research on memory and spatial location, the dorsal and ventral streams of the visual system, and the notion of a cognitive-perceptual system using spatial indexes to exploit the stability of the external world
Thriving Pastors Cohort: Expanding Capacity for Lifelong Ministry
Assemblies of God pastors can expand their capacity for lifelong thriving by avoiding or recovering from ministry fatigue or burnout. The key insights that emerged from my research are as such: 1) Ministers are a vulnerable and largely self-isolating group who need a mechanism for spiritual growth and companionship. 2) There is already good work being accomplished in this arena, but pastoral thriving can be further nuanced and presented in a non-threatening and life-giving way. 3) There is not a singular way to accomplish the task of assisting ministers to engage in ongoing spiritual advancement. The cohort is but one avenue in pursuing pastoral flourishing. My current ministry context is as the Lead Pastor of People’s Church, a 300+- Assemblies of God church located in Winter Haven, Florida. The Thriving Pastors Cohort is a nine-session, in-person, group-based journey for pastors and ministry leaders who desire to avoid ministry burnout and expand their capacity for lifelong ministerial flourishing
Engaging the Paradoxical: Zeno\u27s Paradoxes in Three Works of Interactive Fiction
For over two millennia thinkers have wrestled with Zeno\u27s paradoxes on space, time, motion, and the nature of infinity. In this article we compare and contrast representations of Zeno\u27s paradoxes in three works of interactive fiction, Beyond Zork, The Chinese Room, and A Beauty Cold and Austere. Each of these works incorporates one of Zeno\u27s paradoxes as part of a puzzle that the player must solve in order to advance and ultimately complete the story. As such, the reader must engage more deeply with the paradoxes than he or she would in a static work of fiction. In addition, each of the three works presents a different perspective on the intellectual challenges associated with the paradoxes
Patching the Patchwork Quilt: Reforming the Medicaid Program - The Medicaid Program - The Medicaid Voluntary Contribution and Provider-Specific Tax Amendments of 1991
Congress modified the Medicaid program by restricting states\u27 sources of funding, capping payments to certain hospitals, and altering the relationship between the states and the federal government. While the legislation puts to rest an ongoing dispute between the state and federal governments, it does not improve access to or quality of care nor address fundamental problems with the Medicaid program; it is simply another patch to the patch-work quilt called Medicaid

Immediate Effects of Discourse and Semantic Context in Syntactic Processing: Evidence from Eye-Tracking
We monitored readers' eye-movements to examine the time-course of discourse and semantic influences in syntactic ambiguity resolution. Our results indicate immediate and simultaneous influences of referential context and local semantic fit in the reading of reduced relative clauses (i.e.. The horse raced past the bam fell.). These results support a model of sentence processing in which alternatives of a syntactic ambiguity are differentially activated by the bottom-up input, and syntactically-relevant contextual constraints simultaneously add activation to their supported alternatives. Competition between comparably active alternatives may then cause slowed reading times in regions of ambiguity
Does the Community Reinvestment Act influence lending? an analysis of changes in bank low-income mortgage activity
Anecdotal evidence that the Community Reinvestment Act (CRA) influences the lending behavior of financial institutions has not been uniformly supported by empirical research. We revisit this issue by evaluating changes in low-income mortgage lending at commercial banks over the 1992-96 period. Our empirical results fail to support a hypothesis that banks respond to public and regulatory pressure exerted as a result of a downgrade in CRA rating by increasing low-income mortgage lending. The findings are consistent with the contention that during this period regulators stressed adjustments in the lending process of banks (e.g., documentation of lending program and efforts directed at targeted markets) more than lending performance. The findings underscore the importance of regulatory efforts made later in the decade to more closely link enforcement of the CRA to lending outcomes.Community Reinvestment Act of 1977 ; Mortgages ; Bank loans ; Financial institutions
Spectral convergence in tapping and physiological fluctuations: coupling and independence of 1/f noise in the central and autonomic nervous systems.
When humans perform a response task or timing task repeatedly, fluctuations in measures of timing from one action to the next exhibit long-range correlations known as 1/f noise. The origins of 1/f noise in timing have been debated for over 20 years, with one common explanation serving as a default: humans are composed of physiological processes throughout the brain and body that operate over a wide range of timescales, and these processes combine to be expressed as a general source of 1/f noise. To test this explanation, the present study investigated the coupling vs. independence of 1/f noise in timing deviations, key-press durations, pupil dilations, and heartbeat intervals while tapping to an audiovisual metronome. All four dependent measures exhibited clear 1/f noise, regardless of whether tapping was synchronized or syncopated. 1/f spectra for timing deviations were found to match those for key-press durations on an individual basis, and 1/f spectra for pupil dilations matched those in heartbeat intervals. Results indicate a complex, multiscale relationship among 1/f noises arising from common sources, such as those arising from timing functions vs. those arising from autonomic nervous system (ANS) functions. Results also provide further evidence against the default hypothesis that 1/f noise in human timing is just the additive combination of processes throughout the brain and body. Our findings are better accommodated by theories of complexity matching that begin to formalize multiscale coordination as a foundation of human behavior
