In this article, we discuss a number of challenges with the empirical study of emotion and its relation to moral judgment. We examine a case study involving the moral foreign-language effect, according to which people show an increased utilitarian response tendency in moral dilemmas when using their non-native language. One important proposed explanation for this effect is that using one’s non-native language reduces emotional arousal, and that reduced emotion is responsible for this tendency. We offer reasons to think that there (...) is insufficient evidence for accepting this explanation at present. We argue that there are three themes that constrain our current ability to draw firm empirical conclusions: 1) the frequent use of proxies or partial measures for emotions, 2) the lack of a predictive and generalizable theory of emotion and specific emotion-types, and 3) the obscurity of a baseline level of neutrality with respect to participant emotion. These lessons apply not only to research on the moral foreign-language effect, but to empirical research in moral psychology more generally. (shrink)

This paper responds to two trends in debates about Plato's view of women in the Republic. First, many scholars argue or assume that Plato seeks to minimize the influence of femininity in the ideal city, and to make guardian women themselves as “masculine” as possible. Second, scholars who address the relationship between Plato's views of women and his psychological theory tend to focus on the reasoning and appetitive parts of the tripartite soul. In response to the first point, we argue (...) that the idea that Plato seeks to masculinize/de-feminize the city oversimplifies his treatment of Greek gender norms. Although he does want to eliminate some traditionally feminine qualities from the city, he also seeks to eliminate many masculine qualities as well. Moreover, while he tries to make guardian women more like men in some respects, he simultaneously aims to make guardian men more like Greek women in important ways. Regarding the second point, we argue that this project of reimagining gender norms is illuminated by Plato's psychology, but instead of emphasizing reason and appetite, we show how his views are connected to his account of the third, “spirited” part of the soul, thumos, and its dual hard/soft or aggressive/gentle nature.

Measures and theories of information abound, but there are few formalised methods for treating the contextuality that can manifest in different information systems. Quantum theory provides one possible formalism for treating information in context. This paper introduces a quantum inspired model of the human mental lexicon. This model is currently being experimentally investigated and we present a preliminary set of pilot data suggesting that concept combinations can indeed behave non-separably.

Conceptual combination performs a fundamental role in creating the broad range of compound phrases utilised in everyday language. This article provides a novel probabilistic framework for assessing whether the semantics of conceptual combinations are compositional, and so can be considered as a function of the semantics of the constituent concepts, or not. While the systematicity and productivity of language provide a strong argument in favor of assuming compositionality, this very assumption is still regularly questioned in both cognitive science and philosophy. (...) Additionally, the principle of semantic compositionality is underspecifi ed, which means that notions of both "strong" and "weak" compositionality appear in the literature. Rather than adjudicating between different grades of compositionality, the framework presented here contributes formal methods for determining a clear dividing line between compositional and non-compositional semantics. In addition, we suggest that the distinction between these is contextually sensitive. Compositionality is equated with a joint probability distribution modeling how the constituent concepts in the combination are interpreted. Marginal selectivity is introduced as a pivotal probabilistic constraint for the application of the Bell/CH and CHSH systems of inequalities. Non-compositionality is equated with a failure of marginal selectivity, or violation of either system of inequalities in the presence of marginal selectivity. This means that the conceptual combination cannot be modeled in a joint probability distribution, the variables of which correspond to how the constituent concepts are being interpreted. The formal analysis methods are demonstrated by applying them to an empirical illustration of twenty-four non-lexicalised conceptual combinations. (shrink)

The last decades have seen major advances in the study of gestures both in humans and non-human primates. In this paper, we seriously examine the idea that there may be gestural form types that are shared across great ape species, including humans, which may underlie gestural universals, both in form and meaning. We focus on one case study, the hand fling gesture common to chimpanzees and humans, and provide a semantic analysis of this gesture.

Animal ethicists have recently debated the ethical questions raised by disenhancing animals to improve their welfare. Here, we focus on the particular case of breeding hens for commercial egg-laying systems to become blind, in order to benefit their welfare. Many people find breeding blind hens intuitively repellent, yet ‘welfare-only’ positions appear to be committed to endorsing this possibility if it produces welfare gains. We call this the ‘Blind Hens’ Challenge’. In this paper, we argue that there are both empirical and (...) theoretical reasons why even those adopting ‘welfare-only’ views should be concerned about breeding blind hens. But we also argue that alternative views, which (for example) claim that it is important to respect the telos or rights of an animal, do not offer a more convincing solution to questions raised by the possibility of disenhancing animals for their own benefit.

In this paper, the performance of inverted pendulum have been Investigated using robust control theory. The robust controllers used in this paper are H∞ Loop Shaping Design Using Glover McFarlane Method and mixed H∞ Loop Shaping Controllers. The mathematical model of Inverted Pendulum, a DC motor, Cart and Cart driving mechanism have been done successfully. Comparison of an inverted pendulum with H∞ Loop Shaping Design Using Glover McFarlane Method and H∞ Loop Shaping Controllers for a control target deviation (...) of an angle from vertical of the inverted pendulum using two input signals (step and impulse). The simulation result shows that the inverted pendulum with mixed H∞ Loop Shaping Controller to have a small rise time, settling time and percentage overshoot in the step response and having a good response in the impulse response too. Finally the inverted pendulum with mixed H∞ Loop Shaping Controller shows the best performance in the overall simulation result. (shrink)
