The Surprise Exam Paradox: Disentangling Two Reductios, John N. Williams

John N. WILLIAMS

One tradition of solving the surprise exam paradox, started by Robert Binkley and continued by Doris Olin, Roy Sorensen and Jelle Gerbrandy, construes surprise epistemically and relies upon the oddity of propositions akin to G. E. Moore's paradoxical 'p and I don't believe that p.' Here I argue for an analysis that evolves from Olin's. My analysis is different from hers or indeed any of those in the tradition because it explicitly recognizes that there are two distinct reductios at work in the student's paradoxical argument against the teacher. The weak reductio is easy to fault. Its invalidity determines the …

Justifying Circumstances And Moore-Paradoxical Beliefs: A Response To Brueckner, John N. Williams

John N. WILLIAMS

In 2004, I explained the absurdity of Moore-paradoxical belief via the syllogism (Williams 2004): (1) All circumstances that justify me in believing that p are circumstances that tend to make me believe that p. (2) All circumstances that tend to make me believe that p are circumstances that justify me in believing that I believe that p. (3) All circumstances that justify me in believing that p are circumstances that justify me in believing that I believe that p.

Externalism And Knowledge Of Comparative Content, Yoo Guan Tan

John N. WILLIAMS

Concepts are the constituents of thoughts, which in turn, are the contents of propositional attitudes. They are also what the predicates of our language express. According to a tradition going back to Plato, questions about comparative content – questions of the form Is concept F the same as concept G? – are purely about relations of ideas, and so are answerable a priori. This does not mean that no experience at all is necessary to answer such questions, for experience may be needed to grasp their content. Call a piece of information about Fs extraneous if it is not required …

Moore's Paradoxes And Iterated Belief, John N. Williams

John N. WILLIAMS

I give an account of the absurdity of Moorean beliefs of the omissive form (om) p and I don’t believe that p, and the commissive form (com) p and I believe that not-p, from which I extract a definition of Moorean absurdity. I then argue for an account of the absurdity of Moorean assertion. After neutralizing two objections to my whole account, I show that Roy Sorensen’s own account of the absurdity of his ‘iterated cases’ (om1) p and I don’t believe that I believe that p, and (com1) p and I believe that I believe that not-p, is unsatisfactory. …

Wittgenstein, Moorean Absurdity And Its Disappearance From Speech, John N. Williams

John N. WILLIAMS

G. E. Moore famously observed that to say, "I went to the pictures last Tuesday but I don't believe that I did" would be "absurd." Why should it be absurd of me to say something about myself that might be true of me? Moore suggested an answer to this, but as I will show, one that fails. Wittgenstein was greatly impressed by Moore's discovery of a class of absurd but possibly true assertions because he saw that it illuminates "the logic of assertion". Wittgenstein suggests a promising relation of assertion to belief in terms of the idea that one "expresses …

Superman, Wittgenstein And The Disappearance Of Moorean Absurdity, John N. Williams

John N. WILLIAMS

'You have known me for years, Lois' explains Superman, as I lay aside my copy of Crimmins’s example (1992). 'But there is something you have not yet discovered. You also know me under a disguise. You have not yet realized that this person is I in disguise. On that way of thinking about me, you have different opinions of me. In fact you think me an idiot.' I've just informed Superman that I accept his testimony on the strength of his intelligence. But I confess I don’t quite know how to acknowledge my acceptance of his final remark.

The Ethics Of Placebo-Controlled Trials In Developing Countries To Prevent Mother-To-Child Transmission Of Hiv, John N. Williams

John N. WILLIAMS

Placebo-trials on HIV-infected pregnant women in developing countries like Thailand and Uganda have provoked recent controversy. Such experiments aim to find a treatment that will cut the rate of vertical transmission more efficiently than existing treatments like zidovudine. This scenario is first stated as generally as possible, before three ethical principles found in the Belmont Report, itself a sharpening of the Helsinki Declaration, are stated. These three principles are the Principle of Utility, the Principle of Autonomy and the Principle of Justice. These are taken as voices of moral imperative. But although each has intuitive appeal, it can be shown …

Orwell And Huxley: Making Dissent Unthinkable, John N. Williams

John N. WILLIAMS

In this paper I compare the fictional world depicted by Orwell’s 1984 with that of Huxley’s Brave New World from the point of view of an analytic philosopher. Neither novel should be read as predictions, the accuracy of which can be used to judge them. Rather, both attempt to portray what humanity could conceivably become. The authenticity of this conceivability is a necessary condition of the power of both works to raise central philosophical questions about the human condition. What is ethically wrong with control? How far can Man go in recreating himself? In what sense are these worlds anti-utopian? …

The Life Of An Unknown Assassin: Leon Czolgosz And The Death Of William Mckinley, Cary Federman

Department of Justice Studies Faculty Scholarship and Creative Works

The purpose of this essay is to examine the discourses that surrounded the life of Leon Czolgosz, the assassin of President William McKinley. The gaps in Czolgosz’s life, his peculiar silences, his poor health and the ambiguity and thinness of his confession, rather than taken as instances of mental and physical distress, have, instead, been understood as signs of a revolutionary anarchistic assassin. Czolgosz is an expression of a cultural tradition in somatic form. I argue that the discursive construction of criminality, already present in the late nineteenth century within the medical and human sciences, is what shaped Czolgosz’s life …

Learned Attention In Younger And Older Adults, Jared M. Holder

Masters Theses & Specialist Projects

A relatively new phenomenon in learning research called highlighting occurs when participants show a seemingly irrational preference to attribute a stronger cue-outcome association to a later presented perfect predictor when it is paired with an imperfect predictor than that of an earlier presented perfect predictor paired with the same imperfect predictor (Kruschke, 1996). Current research suggests that the highlighting effect depends on the ability to learn to shift attention away from an irrelevant cue toward a more relevant cue in order to reduce errors in causal judgment and preserve an earlier formed association (Kruschke, 2003). Much research has suggested that …

Evaluation Of Guided Visualizations And The Relationships Among Perceived Stress, Differentiation Of Self, Sense Of Coherence, Dyadic Satisfaction And Quality Of Life, Kim R. Rogers

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study focused on three main areas. These areas involved (1) the relationship among perceived stress, global orientation to life and indicators of physical, psychological and dyadic relational distress, (2) the effect of a brief CBT-based relaxation/guided visualization intervention on these outcome indicators of distress, and (3) changes in physiological indicators during the intervention sessions. The study population was drawn from couples who perceived themselves as living highly stressed lifestyles.

Results suggested that global orientation to life as reflected by differentiation of self inventory (DSI) and sense of coherence scale (SOCS) scale scores mediated the relationship between stress and distress. …

The Multiple-Choice Concept Map (Mccm): An Interactive Computer-Based Assessment Method, Ioan C. Sas

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research attempted to bridge the gap between cognitive psychology and educational measurement (Mislevy, 2008; Leighton & Gierl, 2007; Nichols, 1994; Messick, 1989; Snow & Lohman, 1989) by using cognitive theories from working memory (Baddeley, 1986; Miyake & Shah, 1999; Grimley & Banner, 2008), multimedia learning (Mayer, 2001), and cognitive load (Chandler and Sweller, 1991, 1992; Cerpa, Chandler, & Sweller., 1996) to identify potential design weaknesses of traditional select-and-fill-in (SAFI) concept map assessment and then to guide the design of the new and improved multiple-choice concept map (MCCM) assessment method. The primary objective of this study was to evaluate the …

Causality And Similarity In Autobiographical Event Structure: An Investigation Using Event Cueing And Latent Semantic Analysis, Christopher M. O'Connor

Electronic Thesis and Dissertation Repository

The influence of similarity- and causally-based relations on the organization of autobiographical events was investigated using extended strings of related event memories. These strings were elicited using an event cueing paradigm in which participants generated descriptions of memories from their life, which were then presented as cues to subsequent event memories. In Experiment 1, similarity between generated events was investigated using participants’ similarity ratings, Latent Semantic Analysis, and experimenter judgements of shared event properties. For events close together in a string, event owners’ similarity ratings were higher than non-owners’, and non-owners’ ratings were comparable to similarity calculated using LSA. In …

When Bad Stress Goes Good: Increased Threat Reactivity Predicts Improved Category Learning Performance, Shawn W. Ell, Brandon Cosley, Shannon L. Mccoy

Psychology Faculty Scholarship

The way in which we respond to everyday stressors can have a profound impact on cognitive functioning. Maladaptive stress responses in particular are generally associated with impaired cognitive performance. We argue, however, that the cognitive system mediating task performance is also a critical determinant of the stress-cognition relationship. Consistent with this prediction, we observed that stress reactivity consistent with a maladaptive, threat response differentially predicted performance on two categorization tasks. Increased threat reactivity predicted enhanced performance on an information-integration task (i.e., learning is thought to depend upon a procedural-based memory system), and a (nonsignificant) trend for impaired performance on a …

Toward The Scientific Study Of Autobiographical Memory Narratives In Psychotherapy (Response To Commentaries On Autobiographical Memory Narratives In Psychotherapy: A Coding System Applied To The Case Of Cynthia), Jefferson A. Singer, Laura Bonalume

Psychology Faculty Publications

In responding to Adler (2010) and Moertl, Boritz, Bryntwick, and Angus (2010), we elaborate three areas of discussion: (1) Defining the autobiographical memory narrative unit; (2) Clarifications regarding our approach to coding narrative memories; and (3) Potential future research. Our response highlights the importance of a coding system specific to long-term narrative memories, the need to distinguish clearly what is meant by narrative memory, and the value of creating a bridge between the study of narrative memory in psychotherapy and research in cognitive science and personality psychology.

Autobiographical Memory Narratives In Psychotherapy: A Coding System Applied To The Case Of Cynthia, Jefferson A. Singer, Laura Bonalume

Psychology Faculty Publications

Recent cognitive and psychodynamic oriented therapies have converged on the powerful role that narrative processing plays in psychotherapy. Although previous coding systems have examined specific aspects of memory narratives, there are no comprehensive methods for coding segments of clinical evaluations or psychotherapy sessions that zero in on the unit of a briefly recounted autobiographical memory narrative. The present single case study aims to introduce and to demonstrate the Coding System for Autobiographical Memory Narratives in Psychotherapy (CS-AMNP; Singer & Bonalume, 2008) with a young female client whom we call "Cynthia." We applied this autobiographical memory narrative approach to the diagnostic …

Developing Constructs For Psychopathology Research: Research Domain Criteria, Charles A. Sanislow, Daniel S. Pine, Kevin J. Quinn, Michael J. Kozak, Marjorie A. Garvey, Robert K. Heinssen, Philip Sung-En Wang, Bruce N. Cuthbert

Charles A. Sanislow, Ph.D.

There exists a divide between findings from integrative neuroscience and clinical research focused on mechanisms of psychopathology. Specifically, a clear correspondence does not emerge between clusters of complex clinical symptoms and dysregulated neurobiological systems, with many apparent redundancies. For instance, many mental disorders involve multiple disruptions in putative mechanistic factors (e.g., excessive fear, deficient impulse control), and different disrupted mechanisms appear to play major roles in many disorders. The Research Domain Criteria (RDoC) framework is a heuristic to facilitate the incorporation of behavioral neuroscience in the study of psychopathology. Such integration might be achieved by shifting the central research focus …

The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend

Joseph W. Houpt

The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes. Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.

Pilot Perception Of Light Emitting Diodes Versus Incandescent Elevated Runway Guard Lights, Hilary Stevens

Doctoral Dissertations and Master's Theses

Pilots must understand and be aware of the purpose of each airport sign, light and marking, for there are numerous. The Federal Aviation Administration (FAA) is planning on replacing the current incandescent lighting with far more economical LED airport lighting. In preparation for this change, two experiments were conducted for this thesis. Experiment 1 attempted to determine what pilots know about the meaning of the signs, markings and lights on the taxiways and runways through a questionnaire that was developed with the FAA. Experiment 2 evaluated pilot perception of LED lighting compared to current incandescent elevated runway guard lights.

Remembering To Remember And The Consequences Of Forgetting: The Role Of Prospective Memory In Consumer Intentions, Eyad M. Youssef

Theses and Dissertations in Business Administration

Picking up your dry cleaning after work, returning library books before the due date, picking up a friend at the airport; all of these tasks have one underlying feature that links them together. The tasks cannot be completed when the initial intention is formed. Prospective memory can be defined as remembering to remember (Winograd, 1988). It can also be defined as either remembering to do something at a particular moment in the future or as the timely execution of a previously formed intention (Kvavilashvili and Ellis, 1996). Remembering to do things (prospective memory) is just as much a use of …

Prenatal Undernutrition And Cognitive Function In Late Adulthood, Susanne R. De Rooij, Hans Wouters, Julie E. Yonker, Rebecca C. Painter

University Faculty Publications and Creative Works

At the end of World War II, a severe 5-mo famine struck the cities in the western part of The Netherlands. At its peak, the rations dropped to as low as 400 calories per day. In 1972, cognitive performance in 19-y-old male conscripts was reported not to have been affected by exposure to the famine before birth. In the present study, we show that cognitive function in later life does seem affected by prenatal undernutrition. We found that at age 56 to 59, men and women exposed to famine during the early stage of gestation performed worse on a selective …
