Representation and rationality

David Lewis (1974, 1994/1999) proposed to reduce the facts about mental representation to facts about sensory evidence, dispositions to act, and rationality. Recently, Robert Williams (2020) and Adam Pautz (2021) have taken up and developed Lewis's project in sophisticated and novel ways. In this paper, we aim to present, clarify, and ultimately object to the core thesis that they all build their own views around. The different sophisticated developments and defenses notwithstanding, we think the core thesis is vulnerable. We pose a dilemma by considering the two sides of a current epistemological controversy over the relation between evidence and rational belief: permissivism vs. uniqueness. As we argue, the prospects for the Lewisian project look dim when either supposition is clearly made.     

Can the Mind Command the Body?

People naturally intuit that an agent's ethereal thoughts can cause its body to move. Per intuitive physics; however, one body can only interact with another. Are people, then, covertly puzzled by the capacity of thoughts to command the body? Experiment 1 first confirms that thoughts (e.g., thinking about a cup) are indeed perceived as ethereal—as less detectible in the body (brain), and more likely to exist in the afterlife relative to matched percepts (e.g., seeing a cup). Experiments 2–5 show that thoughts are considered less likely to cause behavior than percepts (e.g., thinking of a cup vs. seeing one). Furthermore, mind–body causation is more remarkable when its bodily consequences are salient (e.g., moving an arm vs. brain activation). Finally, epistemic causes are remarkable only when they are ascribed to mental- (e.g., “thinking”) but not to physical states (“activation”). Together, these results suggest that mind–body interactions elicit a latent dualist dissonance.     

Rational Redundancy in Referring Expressions: Evidence from Event-related Potentials

In referential communication, Grice's Maxim of Quantity is thought to imply that utterances conveying unnecessary information should incur comprehension difficulties. There is, however, considerable evidence that speakers frequently encode redundant information in their referring expressions, raising the question as to whether such overspecifications hinder listeners’ processing. Evidence from previous work is inconclusive, and mostly comes from offline studies. In this article, we present two event-related potential (ERP) experiments, investigating the real-time comprehension of referring expressions that contain redundant adjectives in complex visual contexts. Our findings provide support for both Gricean and bounded-rational accounts. We argue that these seemingly incompatible results can be reconciled if common ground is taken into account. We propose a bounded-rational account of overspecification, according to which even redundant words can be beneficial to comprehension to the extent that they facilitate the reduction of listeners’ uncertainty regarding the target referent.     

Dynamics properties of knowledge acquisition

Repeated counteraction of current knowledge and reality observation generates new knowledge and can be viewed as a dynamic process. When observed objects are not results of human activity, the dynamics results in acquisition of new knowledge, usually as a refinement of the existing one. Otherwise, adjustment between incomplete knowledge and reality can be a result of intentional modification of objects in question, as it happens in design of any artifact. In this case convergence of the process is questionable, for example, it may imply the end of the technical progress. In worst case scenario, the same computable criteria used simultaneously to modify objects and evaluate the result quality causing drift from an established goal and devaluation of acquired knowledge.     

Beyond Existence and Non-Existence

Abstract

When Husserl speaks of the so-called ‘transcendental reduction’ or ‘phenomenological epochē’ many believe that he is eschewing the question of truth or existence. Two reasons are given for this: First, Husserl explicitly states that when we perform the reduction, we should no longer naively ‘accept [the world] as it presents itself to me as factually existing’ (Id I §30, p. 53) and should suspend our judgement with regard to ‘the positing of its actual being’ (Id I §88, p. 182). Second, Husserl seems to have no problem in referring to an ‘object’ of thought even when we refer to non-existent, hallucinatory or indeed impossible objects. This seems to suggest that he is not interested in the question whether or not there is a corresponding ‘ordinary’ object. The paper seeks to question this and will show that his inquiry never loses sight of the questions of truth and existence but rather brings them into the foreground.     

Salesperson directive modification intention: a conceptualization and empirical validation

Salespersons represent an important and challenging set of employees for organizational management. Given frequently high autonomy levels and varied job roles, boundary spanning agents have ample opportunity and motivation to modify/ignore organizational directives. Based on a multi-theoretical perspective, this research sets forth a three-dimensional conceptualization of directive modification intentions and develops and empirically tests a scale designed to better explain this phenomenon while empirically validating its occurrence. Results indicate that boundary spanners have three distinct and relatively stable motivations for modifying/ignoring organizational directives, including customer-, organization-, and self-focused motivations, and that each motivation may potentially relate differently to important antecedent and outcome variables. Managerial and theoretical implications are discussed.     

Thanks for asking: Self-affirming questions reduce backlash when stigmatized targets confront prejudice

Two experiments tested the prediction that stigmatized individuals can avoid backlash when they confront others about bias if they first ask questions designed to activate self-affirmation processes. Experiment 1 showed that compared to a no-strategy control condition, highly prejudiced perceivers tended to express less desire to meet an Arab-American when he asked them to take his perspective on prejudice, but they expressed more desire to meet him when he asked self-affirming questions prior to making the perspective-taking request. Experiment 2 replicated this effect with a different affirmation and revealed that asking self-affirming questions reduced perceptions that the target was being confrontational when asking others to take his perspective. Together, these studies show that stigmatized targets can effectively challenge prejudiced individuals to reduce their biases if they first use a subtle strategy that reduces defensiveness.     

ON THE DISTINCTION BETWEEN REDUCTIVE AND NONREDUCTIVE PHYSICALISM

Abtract: This article argues that the debate between reductive and nonreductive physicalists is best characterized as a disagreement about which properties are natural. Among other things, natural properties are those that characterize the world completely. All physicalists accept the “completeness of physics,” but this claim contains a subtle ambiguity, which results in two conceptions of natural properties. Reductive physicalists should assert, while nonreductive physicalists should deny, that a single set of low‐level physical properties is natural in both of these senses. This way of drawing the distinction succeeds where previous approaches have failed and illuminates why the debate about reductionism is important.     

情绪失调如何引起情绪枯竭？

当服务行业员工内心情感与工作所期望情绪不一致时,如何调节更容易陷入情绪枯竭？该研究抽取服务业员工352名,采用问卷法测量工作环境中的情绪失调、情绪劳动策略及情绪枯竭程度,并探究三者的关系。结果表明,负情绪失调通过较多的表层扮演和失调扮演,导致更多的情绪枯竭;正情绪失调则通过较少的表层扮演和失调扮演,引起较少情绪枯竭。研究对服务业员工招聘、心理培训及人性化管理有一定指导意义。     

The Effects of a Common In‐group Prime on Intentions to Help Indigenous and Homeless Australians

The article reports on research designed to test Australian attitudes towards helping impoverished members of the Australian society, in particular, indigenous and homeless people. Australian university students completed a questionnaire to measure their attitudes towards helping homeless and indigenous people under conditions that primed a common Australian identity. The findings showed that priming an inclusive identity led to relatively stronger intentions to help indigenous Australians but not homeless people. It was also found that participants preferred to endorse more autonomy than dependency help to both indigenous and homeless Australians. Whereas the findings indicate that helping intentions towards those living with poverty may be accentuated by priming a common in‐group, they also imply that helping attitudes vary with the type of help being sought and the way people perceive the cause of someone's poverty.
