Externalism with regard to mental content says that in order to have certain types of intentional mental states (e.g. beliefs), it is necessary to be related to the environment in the right way.

This paper offers a brief historical survey of the development of analytic philosophy in Hong Kong from 1911 to the present day. At first, Western philosophy was a minor subject taught mainly by part-time staff. After the Second World War, research and teaching in analytic philosophy in Hong Kong began to grow and consolidate with the expansion of higher-education and the establishment of new universities. Analytic philosophy has been a significant influence on comparative and Chinese philosophy and played a crucial (...) role in the teaching and promotion of critical thinking. Analytic philosophers in Hong Kong are now active participants in the global philosophical community. We review the development of analytic philosophy across the major tertiary institutions in Hong Kong and discuss some of the future challenges faced by the discipline. (shrink)

There are two popular views regarding the origin of critical thinking: (1) The concept of critical thinking began with Socrates and his Socratic method of questioning. (2) The term ‘critical thinking’ was first introduced by John Dewey in 1910 in his book How We Think. This paper argues that both claims are incorrect. Firstly, critical reflection was a distinguishing characteristic of the Presocratic philosophers, setting them apart from earlier traditions. Therefore, they should be recognized as even earlier pioneers of critical (...) thinking. Secondly, John Dewey not only used the term ‘critical thinking’ before 1910, but there were also other authors who used it before him. The meaning of ‘critical thinking’ at the turn of the twentieth century was shaped by various traditions of linguistic usage, including literary criticism, science and medicine, and Kantian philosophy.

In a range of contexts, individuals arrive at collective decisions by sharing confidence in their judgements. This tendency to evaluate the reliability of information by the confidence with which it is expressed has been termed the ‘confidence heuristic’. We tested two ways of implementing the confidence heuristic in the context of a collective perceptual decision-making task: either directly, by opting for the judgement made with higher confidence, or indirectly, by opting for the faster judgement, exploiting an inverse correlation between confidence (...) and reaction time. We found that the success of these heuristics depends on how similar individuals are in terms of the reliability of their judgements and, more importantly, that for dissimilar individuals such heuristics are dramatically inferior to interaction. Interaction allows individuals to alleviate, but not fully resolve, differences in the reliability of their judgements. We discuss the implications of these findings for models of confidence and collective decision-making. (shrink)

Proposals to lower the age of voting, to 15 for example, are regularly met with worries that people that age are not sufficiently ‘competent’. Notice however that we allow people that age to sign binding legal contracts, provided that those contracts are co-signed by their parents. Notice, further, that in a democracy voters are collectively ‘joint authors’ of the laws that they enact. Enfranchising some less competent voters is no worry, the Condorcet Jury Theorem assures us, so long as the (...) electorate's competence averaging across all voters remains better-than-random.

What is wrong with participating in a democratic decision-making process, and then doing something other than the outcome of the decision? It is often thought that collective decision-making entails being prima facie bound to the outcome of that decision, although little analysis has been done on why that is the case. Conventional perspectives are inadequate to explain its wrongness. I offer a new and more robust analysis on the nature of voting: voting when you will accept the outcome only if (...) the decision goes your way is an act of bad faith: you are not taking part in a ‘process that decides what we will do’. This analysis sheds light on understanding the intrinsic nature of voting and what we are doing when we make decisions collectively. (shrink)

This book is about the basic principles that underlie critical thinking and creativity. The majority of the content is on critical thinking since more topics are naturally involved and since they can be discussed readily and systematically. The last few chapters are devoted to creativity and research methodology, not typical the book's plethora of competition. Each chapter introduces a specific topic, usually by introducing the relevant theories in conjunction with realistic examples that show how the theories can be applied. Each (...) chapter concludes with a set of exercises whose solutions are detailed at the rear of the book. While the writing style is purposefully informal, the presentation is complete, at least with respect to the intended introductory level. (shrink)

The question of whether grammaticality is a binary categorical or a gradient property has been the subject of ongoing debate in linguistics and psychology for many years. Linguists have tended to use constructed examples to test speakers’ judgements on specific sorts of constraint violation. We applied machine translation to randomly selected subsets of the British National Corpus (BNC) to generate a large test set which contains well-formed English source sentences, and sentences that exhibit a wide variety of grammatical infelicities. We (...) tested a large number of speakers through (filtered) crowd sourcing, with three distinct modes of classification, one binary and two ordered scales. We found a high degree of correlation in mean judgements for sentences across the three classification tasks. We also did two visual image classification tasks to obtain benchmarks for binary and gradient judgement patterns, respectively. Finally, we did a second crowd source experiment on 100 randomly selected linguistic textbook example sentences. The sentence judgement distributions for individual speakers strongly resemble the gradience benchmark pattern. This evidence suggests that speakers represent grammatical well-formedness as a gradient property. (shrink)

The 2014 Umbrella Movement was one of the most significant social and political events in recent Hong Kong history. This paper offers some initial reflections on the connections between the movement and broader issues related to civic education, critical thinking, and theories of education. First, it is suggested that the movement closely resembles a form of civic education known as ‘action civics,’ offering an alternative pedagogy that might encourage more authentic civic participation. Second, the movement raises questions about how the (...) teaching of critical thinking can be made more practically relevant to modern citizenship. Third, the deep political polarization associated with the movement indicates that civic education and critical thinking training need to pay attention to cognitive biases that affect political ideology. Finally, the Umbrella Movement reflects the failure of democratization in Hong Kong and coincides with increasing political pressures on the local education system. We discuss how political reality connects to issues about democratic education, critical pedagogy, and the idea of political neutrality in education. (shrink)

Nussbaum’s theory of the emotions draws heavily on the Stoic account. In her theory, emotions are a kind of value judgment or thought. This is in stark contrast to the well-known proposal from William James, who took emotions to be bodily feelings. There are various motivations for taking emotions as judgments. One main reason is that emotions are intentional mental states. They are always about something, directed at particular objects or state of affairs. For example, fear seems to involve the (...) anticipation of danger. To grief for the passing of a loved one involves the thought that someone dear to us is now gone. In Upheavals of Thought and also in her Hochelaga Lecture, Nussbaum analyzed compassion as a set of judgments, including for example the judgment that someone is experiencing serious suffering, and that the person in question does not deserve the suffering.

Pietroski (1993) offers a semantics for belief sentences that is supposed to address the problem of equivalence. This paper argues that his proposal fails to solve the problem.

Bermúdez argues for rational framing effects in the form of quasi-cyclical preferences. This is supposed to refute the extensionality principle in standard decision theory. In response, I argue that it is better to analyze seemingly quasi-cyclical preferences as ceteris paribus preferences. Furthermore, if frames are included as objects of choice, we can acknowledge rational framing effects without rejecting extensionality.

There is a paucity of experimental data addressing how peers influence adolescent risk-taking. Here, we examined peer effects on risky decision-making in adults and adolescents using a virtual social context that enabled experimental control over the peer “interactions”. 40 adolescents (age 11-18) and 28 adults (age 20-38) completed a risk-taking (Wheel of Fortune) task under 4 conditions: in private; while being observed by (fictitious) peers; and after receiving ‘risky’ or ‘safe’ advice from the peers. For high-risk gambles (but not medium-risk (...) or even gambles), adolescents made more risky decisions under peer observation than adults. Adolescents, but not adults, tended to resist ‘safe’ advice for high-risk gambles. Although both groups tended to follow ‘risky’ advice for high-risk gambles, adults did so more than adolescents. These findings highlight the importance of distinguishing between the effects of peer observation and peer advice on risky decision-making. (shrink)

ABSTRACTDifficulties with inhibiting fear have been associated with the emergence of anxiety problems and poor response to cognitive–behavioural treatment. Fear inhibition problems measured using experimental paradigms involving aversive stimuli may be inappropriate for vulnerable samples and may not capture fear inhibition problems evident in everyday life. We present the Fear Inhibition Questionnaire, a self-report measure of fear inhibition abilities. We assess the FIQ’s factor structure across two cultures and how well it correlates with fear inhibition indices derived experimentally. Adolescent participants (...) from Hong Kong and England completed the FIQ, with the English participants also completing a conditioning and extinction task to assess fear inhibition problems. Across both cultures, the FIQ showed a single factor structure and low FIQ scores, or worse fear inhibition problems, were associated with self-reports of heightened anxiety. Correlation of FIQ scores with experimental indices, whi... (shrink)

(1) It is not clear from Gold and Stoljar’s definition of biological neuroscience whether it includes computational and representational concepts. If so, then their evaluation of Kandel’s theory is problematic. If not, then a more direct refutation of the radical neuron doctrine is available. (2) Objections to the psychological sciences might derive not just from the conflation of the radical and the trivial neuron doctrine. There might also be the implicit belief that for many mental phenomena, adequate theories must invoke (...) neurophysiological concepts and cannot be purely psychological. (shrink)

One major obstacle in providing a compositional semantics for natural languages is that it is not clear how we should deal with propositional attitude contexts. In this paper I will discuss the Interpreted Logical Form proposal , focusing on the case of belief. This proposal has been developed in different ways by authors such as Harman (1972), Higginbotham (1986,1991), Segal (1989) and Larson and Ludlow (1993). On this approach, the that-clause of a belief report is treated as a singular term, (...) referring to the interpreted logical form (ILF) of its embedded sentence. The ILF of a sentence is made up of two parts : a syntactic representation of the sentence at the level of logical form, and an assignment of semantic values to parts of the representation. Thus, given a belief report such as. (shrink)

Background: Parkinson’s disease is a neurodegenerative disease in which the progressive loss of dopaminergic neurons leads to initially sporadic and eventually widespread damage of the nervous system resulting in significant musculoskeletal and cognitive deterioration. Loss of motor function alongside increasing cognitive impairment is part of the natural disease progression. Gait is often considered an automatic activity; however, walking is the result of a delicate balance of multiple systems which maintain the body’s center of mass over an ever-changing base of support. (...) It is a complex motor behavior that requires components of attention and memory to prevent falls and injury. In addition, evidence points to the critical role of salient visual information to gait adaptability. There is a growing understanding that treatment for PD needs to address movement as it occurs naturally and walking needs to be practiced in more complex environments than traditional therapy has provided.MethodsIn this single-blinded randomized-controlled pilot study, an immersive treadmill training was piloted to determine feasibility and preliminary efficacy on gait and cognition in people with PD. Eighteen participants with Hoehn and Yahr stages I-III PD were randomized to either an intervention or a waitlist control group. Following baseline data collection, the intervention group trained for 30 min, three times/week for 4 weeks on a split belt treadmill combined with a first-person immersive video game targeting visuospatial skills and working memory. Assessment was repeated after 4 weeks of training for the experimental group and 1-month after baseline for the control group. Primary motor outcomes were captured with the APDM Opal sensors during 6 MWT, TUG, and TUG Cognitive. Secondary outcomes of cognition were measured with the Montreal Cognitive Assessment, Verbal Fluency and the Symbol Digit Modality Test. Within subject differences were calculated using the Wilcoxon Signed Ranked Test and between subject comparisons were analyzed using the Mann Whitney U-test.ResultsThis novel treadmill training program was well-tolerated with all participants in the intervention group completing 4 weeks of training three times a week without any adverse effects. After immersive cognitive motor training, the experimental group made clinically relevant improvements in gait speed and walking distance during the 6 MWT while members of the control group showed no change or decreased gait speed and walking distance over the 1-month trial. In addition, the experimental group demonstrated significant improvement for the TUG Cognitive and those changes were greater than the control group. The experimental group also improved scores on MoCA and SDMT cognitive outcome measures while the control group did not.ConclusionThe use of immersive gaming technology to engage specific areas of cognition related to gait is feasible in PD. The treadmill training program paired with a customized interactive video game improved walking velocity in addition to non-significant but consistent improvements in other gait measures and cognitive performance in participants with early to mid-stage PD.

This paper is about possible worlds semantics for propositional attitude sentences. In particular I shall focus on belief reports in English such as "Lusina believes that tofu is nutritious." It is well-known that possible worlds semantics for such reports suffers from the so-called _problem of equivalence_ . In this paper I shall examine some attempts to deal with this problem and argue that they are unsatisfactory.

Rhythm is key to language acquisition. Across languages, rhythmic features highlight fundamental linguistic elements of the sound stream and structural relations among them. A sensitivity to rhythmic features, which begins in utero, is evident at birth. What is less clear is whether rhythm supports infants' earliest links between language and cognition. Prior evidence has documented that for infants as young as 3 and 4 months, listening to their native language supports the core cognitive capacity of object categorization. This precocious link (...) is initially part of a broader template: listening to a non-native language from the same rhythmic class as and to vocalizations of non-human primates provide English-acquiring infants the same cognitive advantage as does listening to their native language. Here, we implement a machine-learning approach to ask whether there are acoustic properties, available on the surface of these vocalizations, that permit infants' to identify which vocalizations are candidate links to cognition. We provided the model with a robust sample of vocalizations that, from the vantage point of English-acquiring 4-month-olds, either support object categorization or fail to do so. We assess whether supervised ML classification models can distinguish those vocalizations that support cognition from those that do not, and which class of acoustic features best support that classification. Our analysis reveals that principal components derived from rhythm-relevant acoustic features were among the most robust in supporting the classification. Classifications performed using temporal envelope components were also robust. These new findings provide in principle evidence that infants' earliest links between vocalizations and cognition may be subserved by their perceptual sensitivity to rhythmic and spectral elements available on the surface of these vocalizations, and that these may guide infants' identification of candidate links to cognition.

Cognitive science aims to provide scientific explanations of various mental phenomena. Attempts to study the mind, however, go back thousands of years, and what is distinctive about cognitive science is not its aim but the use of computations and representations in psychological explanations. We shall discuss whether the computational approach comes under challenge from dynamics, and look at some of the main themes in recent developments in cognitive science. In the final part of this paper we shall look at two (...) areas where cognitive science might provide significant benefits to the contemporary world. (shrink)

of (from British Columbia Philosophy Graduate Conference) In moral reasoning, we sometimes encounter situations where what our ethical principles tell us to do and what we actually do conflict. In legal ethics, such anomalies arise for lawyers in defending a client who commits perjury. Wallace argues that such lawyers have not mastered the practice of truth-telling, and thus suffer from some sort of moral deficiency. However, due to the complexities of legal practice, particularly the value of truth and evidence, lawyers (...) must learn to accommodate cases of perjury into their moral taxonomies, and this is not a simple feat. In addition, I examine the ethics of lying in everyday life, such as in cases of protecting reputation or feelings. As such, I posit that Wallace is oversimplifying the situation and individuals in “perjured client” cases actually have a better and more realistic grasp on the exercise of practical ethics than he claims.

In everyday life, we typically explain what people do by attributing mental states such as beliefs and desires. Such mental states belong to a class of mental states that are _intentional_, mental states that have content. Hoping that Johnny will win, and believing that Johnny will win are of course rather different mental states that can lead to very different behaviour. But they are similar in that they both have the same content : what is being hoped for and believed (...) is the very same thing. According to the thesis of externalism that has been defended most notably by Hilary Putnam and Tyler Burge, not all of the contents of our mental states are determined by our intrinsic properties. Instead, the contents of our beliefs and desires are often determined in part by our relations to the environment. They are, so to speak, "wide" contents that are "not in our heads." Although externalism is accepted by most philosophers, many have argued that mental states with wide contents must also have a kind of content wholly determined by the intrinsic properties of the individuals who are in those states. This kind of content is called "narrow content". The aim of this paper is to distinguish between three rather different motivations for postulating narrow content. I argue that, given a certain conception of narrow content that I shall explain below, none of these three motivations succeed in establishing the existence of narrow content. (shrink)

Michael Tye’s book is a powerful defense of the controversial theory that the phenomenal properties of our conscious mental states are representational in character. The theory is introduced and defended through discussing ten philosophical problems about consciousness. The book is clearly written and arguments are illustrated with interesting thought-experiments and empirical findings. It is one of those delightful occasions where a book is of interest both to professional philosophers and students.
