Latent Inhibition Depends on Inhibitory Attentional Learning to the Preexposed Stimulus: Evidence from Visual Search and Rule-Learning Tasks

Latent inhibition (LI) refers to findings of poorer learning with stimuli preexposed as irrelevant, compared to novel stimuli. In order to investigate the role of attention in traditional LI, two experiments with human subjects were conducted. Experiment 1 used a simplified visual-search design. As in previous studies, but now with a simpler design, there was a LI-like effect, thereby supporting the position that attentional learning to irrelevantly preexposed stimuli is reduced. Experiment 2 introduced conditions that were designed to exclude a potential contribution of novel popout to the visual-search LI-like effect. It was shown that the effect could be observed independently of contributions from novel popout. In addition, when participants were divided into good and poor attentional learners on the basis of visual-search LI scores, traditional rule-learning LI was established in good attentional learners, whereas it was absent in poor attentional learners. Together, these results indicate that visual-search procedures can be used to provide a measure for LI, and, as such, they support attention-based explanations of traditional LI.     

The Problem of Confucian Moral Cultivation and Its Solution: Using Ritual Propriety to Support Rule by Law

Thinking about the decline of morality in post-reform China,the author analyzes the development of virtuous governance based on moral education,and concludes that the reason why ancient rulers were so infatuated with it was the inhibitive function of public evaluation on moral transgressions in familiar neighborhoods.However,as China transforms into a dynamic and commercial society,and its people move from familiar neighborhoods to alienated communities in the cities,public evaluation is losing its power over moral transgressors.To prevent the collapse of the moral system,it is necessary to use rule by law to foster people's sense of justice and rule-consciousness-not to simply hope for the appearance of more altruists.This is possible because law is the embodiment of moral principle,and because legal restraints and penalties can be internalized as habits.After a sense of justice and rule-consciousness has been established in people,we can again take up Confucian virtue education to nurture people's sense of shame and dignity,and their humane and righteous mind.However,to stop the current chaos and corruption,it is urgent that we adopt rule by law and supplement it with moral education.     

Moral uncertainty and permissibility: Evaluating Option Sets

In this essay, we explore an issue of moral uncertainty: what we are permitted to do when we are unsure about which moral principles are correct. We develop a novel approach to this issue that incorporates important insights from previous work on moral uncertainty, while avoiding some of the difficulties that beset existing alternative approaches. Our approach is based on evaluating and choosing between option sets rather than particular conduct options. We show how our approach is particularly well-suited to address this issue of moral uncertainty with respect to agents that have credence in moral theories that are not fully consequentialist.     

Two types of debunking arguments

Debunking arguments are arguments that seek to undermine a belief or doctrine by exposing its causal origins. Two prominent proponents of such arguments are the utilitarians Joshua Greene and Peter Singer. They draw on evidence from moral psychology, neuroscience, and evolutionary theory in an effort to show that there is something wrong with how deontological judgments are typically formed and with where our deontological intuitions come from. They offer debunking explanations of our emotion-driven deontological intuitions and dismiss complex deontological theories as products of confabulatory post hoc rationalization. Through my discussion of Greene and Singer’s empirically informed debunking of deontology, I introduce the distinction between two different types of debunking arguments. The first type of debunking argument operates through regular undercutting defeat, whereas the second type relies on higher-order evidence. I argue that the latter type of debunking argument, of which the argument from confabulation is an example, is objectionably sloppy and therefore inadmissible in academic discussion.     

Does Semantics Need Normativity? Comments on Allan Gibbard,Meaning and Normativity

In the book Gibbard proposes, first, that statements about meaning are normative statements and, second, that they can be given an expressivist treatment, along the lines of Gibbard’s preferred metaethics. In my paper, I examine the first step: The claim that meaning statements are to be construed as being normative, as involving ‘oughts’. Gibbard distinguishes two versions of the normativity of meaning thesis – a weak version, according to which every means implies an ought, and a strong version, according to which for every means, there is an ought that implies it. I argue that neither thesis withstands scrutiny. The weak thesis depends on assumptions about the notion of semantic correctness that the anti-normativist rejects, and the strong thesis does not solve the problems Gibbard wants it to solve: the problems of indeterminacy and meaning skepticism. I conclude that semantics does not need normativity.

How Affect Shapes Risky Choice: Distorted Probability Weighting Versus Probability Neglect

People's choices between prospects with relatively affect‐rich outcomes (e.g., medical side effects) can diverge markedly from their choices between prospects with relatively affect‐poor outcomes (e.g., monetary losses). We investigate the cognitive mechanisms underlying this “affect gap” in risky choice. One possibility is that affect‐rich prospects give rise to more distortion in probability weighting. Another is that they lead to the neglect of probabilities. To pit these two possibilities against each other, we fitted cumulative prospect theory (CPT) to the choices of individual participants, separately for choices between options with affect‐rich outcomes (adverse medical side effects) and options with affect‐poor outcomes (monetary losses); additionally, we tested a simple model of probability neglect, the minimax rule. The results indicated a qualitative difference in cognitive mechanisms between the affect‐rich and affect‐poor problems. Specifically, in affect‐poor problems, the large majority of participants were best described by CPT; in affect‐rich problems, the proportion of participants best described by the minimax rule was substantially higher. The affect gap persisted even when affect‐rich outcomes were supplemented by numerical information, thus providing no support for the thesis that choices in affect‐rich and affect‐poor problems diverge because the information provided in the former is nonnumerical. Our findings suggest that the traditional expectation‐based framework for modeling risky decision making may not readily generalize to affect‐rich choices.

Aquinas and modern consequentialism

Because the moral philosophy of St Thomas Aquinas is egoistic while modern consequentialism is impartialistic, it might at first appear that the former cannot, while the latter can, provide a common value on the basis of which inter‐personal conflicts may be settled morally. On the contrary, in this paper I intend to argue not only that Aquinas’ theory does provide just such a common value, but that it is more true to say of modern consequentialism than of Thomism that it gives in to the partiality of different interests and fails to provide a robust common value on the basis of which disagreements may be settled morally. This is so primarily because the egoism of Aquinas represents a fundamental commitment to personal moral development which is absent from modern teleological theories.     

Beyond Data Collection: Ethical Issues in Minority Research

This article examines ethical concerns surrounding research on minority issues. Specifically, it addresses whether researchers have an obligation to consider (a) the impact that minority research can have on vulnerable populations and (b) their own backgrounds before conducting or assessing minority research for publication. The article argues for such an obligation mainly from a consequentialist perspective and then explores possible strategies for assessing and meeting that obligation. Finally, it explores the possible negative secondary effects of those strategies and censorship concerns.     

Kantian and Consequentialist Ethics: The Gap Can Be Bridged

Richard Hare argues that the fundamental assumptions of Kant's ethical system should have led Kant to utilitarianism, had Kant not confused a norm's generality with its universality, and hence adopted rigorist, deontological norms. Several authors, including Jens Timmermann, have argued contra Hare that the gap between Kantian and utilitarian/consequentialist ethics is fundamental and cannot be bridged. This article shows that Timmermann's claims rely on a systematic failure to separate normative and metaethical aspects of each view, and that Hare's attempt to bridge the gap between Kantian and consequentialist ethics is immune to Timmermann's criticisms. Furthermore, the term “Kantian ethics” is often misleading, and should typically be qualified as either “Kantian rationalism” or “Kantian deontology” in order to avoid confusions of the sort Timmermann falls into.
