    The Probability of Conditionals: The Psychological Evidence.Jonathan St B. Evans David E. Over - 2003 - Mind and Language 18 (4):340-358.
    : The two main psychological theories of the ordinary conditional were designed to account for inferences made from assumptions, but few premises in everyday life can be simply assumed true. Useful premises usually have a probability that is less than certainty. But what is the probability of the ordinary conditional and how is it determined? We argue that people use a two stage Ramsey test that we specify to make probability judgements about indicative conditionals in natural language, and we describe (...)

    Uncertain premises and Jeffrey's rule.David E. Over & Constantinos Hadjichristidis - 2009 - Behavioral and Brain Sciences 32 (1):97-98.
    Oaksford & Chater (O&C) begin in the halfway Bayesian house of assuming that minor premises in conditional inferences are certain. We demonstrate that this assumption is a serious limitation. They additionally suggest that appealing to Jeffrey's rule could make their approach more general. We present evidence that this rule is not limited enough to account for actual probability judgements.

    The new paradigm and massive modalization: Commentary on Knauff and Gazzo Castañeda (2023).David E. Over - 2023 - Thinking and Reasoning 29 (3):389-395.
    Knauff and Gazzo Castañeda argue as much in support of revised mental model theory (RMMT) as they argue against talk of a new paradigm caused by the probabilistic approach in the psychology of reasoning. They claim that RMMT is not essentially different from classical mental model theory (CMMT) and not essentially different from the probabilistic approach. There are many serious questions to ask about RMMT. But RMMT is a massive modalization of aspects of the extensional CMMT, and it follows the (...)

    Barbey & Sloman (B&S) relegate the logical rule of the excluded middle to a footnote. But this logical rule is necessary for natural sampling. Making the rule explicit in a logical tree can make a problem easier to solve. Examples are given of uses of the rule that are non-constructive and not reducible to a domain-specific module.

    A study is reported testing two hypotheses about a close parallel relation between indicative conditionals, if A then B , and conditional bets, I bet you that if A then B . The first is that both the indicative conditional and the conditional bet are related to the conditional probability, P(B|A). The second is that de Finetti's three-valued truth table has psychological reality for both types of conditional— true , false , or void for indicative conditionals and win , lose (...)

  21. Uncertainty and the de Finetti tables.Jean Baratgin, David E. Over & Guy Politzer - 2013 - Thinking and Reasoning 19 (3-4):308-328.
    The new paradigm in the psychology of reasoning adopts a Bayesian, or prob- abilistic, model for studying human reasoning. Contrary to the traditional binary approach based on truth functional logic, with its binary values of truth and falsity, a third value that represents uncertainty can be introduced in the new paradigm. A variety of three-valued truth table systems are available in the formal literature, including one proposed by de Finetti. We examine the descriptive adequacy of these systems for natural language (...)

    Deduction from Uncertain Premises.Rosemary J. Stevenson & David E. Over - 1995 - Quarterly Journal of Experimental Psychology Section A 48 (3):613-643.
    We investigate how the perceived uncertainty of a conditional affects a person's choice of conclusion. We use a novel procedure to introduce uncertainty by manipulating the conditional probability of the consequent given the antecedent. In Experiment 1, we show first that subjects reduce their choice of valid conclusions when a conditional is followed by an additional premise that makes the major premise uncertain. In this we replicate Byrne. These subjects choose, instead, a qualified conclusion expressing uncertainty. If subjects are given (...)

    Reasoning from uncertain premises: Effects of expertise and conversational context.Rosemary J. Stevenson & David E. Over - 2001 - Thinking and Reasoning 7 (4):367 – 390.
    Four experiments investigated uncertainty about a premise in a deductive argument as a function of the expertise of the speaker and of the conversational context. The procedure mimicked everyday reasoning in that participants were not told that the premises were to be treated as certain. The results showed that the perceived likelihood of a conclusion was greater when the major or the minor premise was uttered by an expert rather than a novice (Experiment 1). The results also showed that uncertainty (...)

    Probability and choice in the selection task.David W. Green, David E. Over & Robin A. Pyne - 1997 - Thinking and Reasoning 3 (3):209-235.
    Two experiments using a realistic version of the selection task examined the relationship between participants' probability estimates of finding a counter example and their selections. Experiment 1 used everyday categories in the context of a scenario to determine whether or not the number of instances in a category affected the estimated probability of a counter-example. Experiment 2 modified the scenario in order to alter participants' estimates of finding a specific counter-example. Unlike Kirby 1994a, but consistent with his proposals, both studies (...)

    Reaching a decision: A reply to Oaksford.David W. Green & David E. Over - 1998 - Thinking and Reasoning 4 (2):187-192.
    In his commentary, Oaksford makes two main claims: (1) that the externalisation method used by Green, Over, and Pyne (1997) enforces the correlation observed between probability estimates and selection, and (2) that these estimates support the prediction of a downward revision of P(p) when P(p) > P(q). In this reply, we rebut claim 1 by describing the instructions more comprehensively, and claim 2 by reiterating the importance of making certain theoretical distinctions which Oaksford does not make. Our interest is (...)

    A Minimal Characterization of Indeterminacy.David E. Taylor - 2018 - Philosophers' Imprint 18.
    The current literature on indeterminacy centers around two projects. One concerns the logic of indeterminacy; the other concerns its nature or source. The aim of this paper is to introduce, motivate and go some way toward addressing a new, third project: that of providing what I call a minimal characterization of indeterminacy. An MC, to a first approximation, is a relatively pre-theoretical characterization of indeterminacy that is neutral between the various substantive theories of the nature and logic of indeterminacy. An (...)

    The Psychology of Uncertainty and Three-Valued Truth Tables.Jean Baratgin, Guy Politzer, David E. Over & Tatsuji Takahashi - 2018 - Frontiers in Psychology 9:394374.
    Psychological research on people’s understanding of natural language connectives has traditionally used truth table tasks, in which participants evaluate the truth or falsity of a compound sentence given the truth or falsity of its components in the framework of propositional logic. One perplexing result concerned the indicative conditional if A then C which was often evaluated as true when A and C are true, false when A is true and C is false but irrelevant“ (devoid of value) when A is (...)

    Simulating a Skilled Typist: A Study of Skilled Cognitive‐Motor Performance.David E. Rumelhart & Donald A. Norman - 1982 - Cognitive Science 6 (1):1-36.
    We review the major phenomena of skilled typing and propose a model for the control of the hands and fingers during typing. The model is based upon an Activation‐Trigger‐Schema system in which a hierarchical structure of schemata directs the selection of the letters to be typed and, then, controls the hand and finger movements by a cooperative, relaxation algorithm. The interactions of the patterns of activation and inhibition among the schemata determine the temporal ordering for launching the keystrokes. To account (...)

These files are created by Institutions who prosecute a case of possible research misconduct; ORI has oversight review of these investigations.

    Probabilities of conditionals and previsions of iterated conditionals.Giuseppe Sanfilippo, Angelo Gilio, David E. Over & Niki Pfeifer - 2020 - International Journal of Approximate Reasoning 121.
    We analyze selected iterated conditionals in the framework of conditional random quantities. We point out that it is instructive to examine Lewis's triviality result, which shows the conditions a conditional must satisfy for its probability to be the conditional probability. In our approach, however, we avoid triviality because the import-export principle is invalid. We then analyze an example of reasoning under partial knowledge where, given a conditional if A then Cas information, the probability of A should intuitively increase. We explain (...)

    Iterated conditionals of the form If p, then if q, r are an important topic in philosophical logic. In recent years, psychologists have gained much knowledge about how people understand simple conditionals, but there are virtually no published psychological studies of iterated conditionals.

    Categorical induction from uncertain premises: Jeffrey's doesn't completely rule.Constantinos Hadjichristidis, Steven A. Sloman & David E. Over - 2014 - Thinking and Reasoning 20 (4):405-431.
    Studies of categorical induction typically examine how belief in a premise (e.g., Falcons have an ulnar artery) projects on to a conclusion (e.g., Robins have an ulnar artery). We study induction in cases in which the premise is uncertain (e.g., There is an 80% chance that falcons have an ulnar artery). Jeffrey's rule is a normative model for updating beliefs in the face of uncertain evidence. In three studies we tested the descriptive validity of Jeffrey's rule and a related probability (...)

    Supervaluationism and branching indeterminacy.David E. Taylor - 2021 - Analytic Philosophy 62 (2):141-164.
    One of the most popular and enduring approaches to indeterminacy phenomena (e.g., vagueness) over the past several decades has been some form or another of supervaluationism. I argue that supervaluationism is inadequate as a model of indeterminacy: There is an entire class of examples of indeterminacy, characterized by a common “branching” structure, that cannot be modeled in the way supervaluationism proposes. I demonstrate my conclusion explicitly with respect to two specific examples—indeterminate personal identity and indeterminate reference—showing how supervaluationism can (...)

    Rationality in the selection task: Epistemic utility versus uncertainty reduction.Jonathan St B. T. Evans & David E. Over - 1996 - Psychological Review 103 (2):356-363.
    M. Oaksford and N. Chater presented a Bayesian analysis of the Wason selection task in which they proposed that people choose cards in order to maximize expected information gain as measured by reduction in uncertainty in the Shannon-Weaver information theory sense. It is argued that the EIG measure is both psychologically implausible and normatively inadequate as a measure of epistemic utility. The article is also concerned with the descriptive account of findings in the selection task literature offered by Oaksford and (...)

    Codes and culture at the courier-journal: Complexity in ethical decision making.David E. Boeyink - 1998 - Journal of Mass Media Ethics 13 (3):165 – 182.
    This study examines the way ethical decisions are made in controversial cases at The Courier-Journal in Louisville, Kentucky, to see if codes of ethics can be efective at a newspaper known for its commitment to ethics. The study concludes that a code is efective in that environment especially on conflict-of-interest questions. A critical factor in the code's efectiveness is an ethical culture in which editors support ethical standards vigorously and foster a process that encourages newsroom debate over controversial cases.
