A beginner's guide to eye tracking for psycholinguistic studies of reading.

Eye tracking has been a popular methodology used to study the visual, cognitive, and linguistic processes underlying word recognition and sentence parsing during reading for several decades. However, the successful use of eye tracking requires researchers to make deliberate choices about how they apply this technique, and there is wide variability across labs and fields with respect to which choices are "standard." We aim to provide an easy-to-reference guideline that can help new researchers with their entrée into eye-tracking-while-reading research. Because the standards do - and should - vary from field to field or study to study as is appropriate for the research question, we do not set a rigid recipe for handling eye tracking data, but rather provide a conceptual framework within which researchers can make informed decisions about how to treat their data so that it is most informative for their research question. Therefore, this paper provides a description of eye movements in reading and an overview of psycholinguistic research on the topic, an overview of experiment design considerations, a description of the data processing pipeline and important choice points and implications, an overview of common dependent measures and their calculation, and a summary of resources for data analysis.

Coach Assist: Assessing Youth Basketball Coaches’ Feedback on Participation in an Acceptance and Commitment Therapy-Based Intervention Incorporating Self-Determination Theory Principles

This paper introduces a pioneering intervention program based mainly on Acceptance and Commitment Therapy, designed to address the multifaceted challenges faced by sports coaches. In order to provide a more comprehensive intervention that bolsters coaches’ intra- and interpersonal skills, principles from Self-Determination Theory have been integrated as a complementary framework. The program was nationally implemented across 32 youth basketball clubs, engaging 172 coaches. These coaches participated in a four-session series, focusing on diverse facets including value exploration, awareness of behavioral functions (“choice point”), self-regulation techniques, and strategies to meet athletes’ basic psychological needs. Out of these, 108 coaches from 26 participating clubs filled out the online feedback form at the end of the intervention, highlighting their experiences, benefits, and areas of improvement within the program. Coaches’ feedback indicated that the program furnished an effective framework for sports coaching, suggesting enhancements in coaches’ abilities to navigate their challenges. Practical recommendations have been administered based on the coaches’ feedback.

Navigating the Institutional Review Board and other institutional entities: An ode to aspiring YPAR scholars.

Youth-led participatory action research (YPAR) engages young people as partners in rigorous research inquiry to guide and inform collective action. Scholars interested in YPAR have notable investment in social justice and activist values, which at times come in direct tensions within their doctoral training and/or professional roles within academia. One monumental hurdle in conducting YPAR is obtaining approval from the Institutional Review Board (IRB). The goal of this manuscript, therefore, is to transparently and humbly share some of the heart work we have done in navigating the IRB. In partnership with IRB directors who are co-authors, we discuss several choice points in obtaining IRB approval. Challenges include: (1) advocating for youth to have co-investigator status on the IRB application, (2) training youth in research ethics, (3) strategically crafting a YPAR application that attends to the evolving and emerging nature of the research, (4) obtaining approval to compensate youth for their time as researchers, and (5) planning for diverse youth dissemination strategies that may challenge principles of anonymity. In discussing these choice points, we will share examples from our own work, strategies, and resources to support current and future aspiring YPAR scholars.

Constitutivism's plight: inescapability, normativity, and relativism

Abstract Constitutivists often argue that agency is inescapable. This is supposed to, among other things, explain why norms that are constitutive of agency are forceful. But can some form of inescapability do that? I consider four types of inescapability—psychological, further factor, standpoint, and plight—and evaluate whether they manage to explain four necessary features of normative force: that it does not vary with desire change, that ought-implies-can and can-fail, and that we are criticizable for failing to live up to forceful norms. The former three all fail to explain some of these features, but a version of plight inescapability does, in fact, appear able to explain them all. This is good news for constitutivists. The catch? The plight inescapability explanation generates relativism. This leaves constitutivists at a choice point: accept the plight inescapability explanation of normative force and relativism—or give up the plight inescapability explanation.

Embedding equity and inclusion in universities through motivational theory and community-based conservation approaches.

Despite widespread plans to embed justice, equity, decolonization, indigenization, and inclusion (JEDII) into universities, progress toward deeper, systemic change is slow. Given that many community-based conservation (CBC) scholars have experience creating enduring social change in diverse communities, they have transferable skills that could help embed JEDII in universities. We synthesized the literature from CBC and examined it through the lens of self-determination theory to help identify generalizable approaches to create resilient sociocultural change toward JEDII in universities. Fostering autonomous motivation (i.e., behaving because one truly values and identifies with the behavior or finds behavior inherently satisfying) is critical to inspiring enduring change in both CBC and JEDII. Based on theory and our examination of CBC, we provide 5 broad recommendations that helped motivate behavioral change in a way that was self-sustained (i.e., even without external rewards or pressure). Guiding principles support autonomy by creating meaningful choice and different entry points for JEDII; prioritising relationships; designing payment programs that enhance autonomous motivation; developing meaningful educational opportunities that are relevant, timely, relational, and authentic; and creating institutional change by focusing efforts on critical moments.

A cell-autonomous role for primary cilium-mediated signaling in long-range commissural axon guidance.

Ciliopathies are characterized by the absence or dysfunction of primary cilia. Despite the fact that cognitive impairments are a common feature of ciliopathies, how cilia dysfunction affects neuronal development has not been characterized in detail. Here, we show that primary cilium-mediated signaling is required cell-autonomously by neurons during neural circuit formation. In particular, a functional primary cilium is crucial during axonal pathfinding for the switch in responsiveness of axons at a choice point or intermediate target. Using different animal models and in vivo, ex vivo and in vitro experiments, we provide evidence for a crucial role of primary cilium-mediated signaling in long-range axon guidance. The primary cilium on the cell body of commissural neurons transduces long-range guidance signals sensed by growth cones navigating an intermediate target. In extension of our finding that Shh is required for the rostral turn of post-crossing commissural axons, we suggest a model implicating the primary cilium in Shh signaling upstream of a transcriptional change of axon guidance receptors, which in turn mediate the repulsive response to floorplate-derived Shh shown by post-crossing commissural axons.

Russia, Ukraine and the climate crisis: Transforming circuits of power

The paper addresses a history of the present, doing so in relation to UN Sustainable Development Goal #13, that of taking urgent action to combat climate change. It uses key concepts from the circuits of power framework (Clegg 1989; 2023) to do so; notably the idea of social and system integration, adapted from Lockwood (1964). The focus is on the impact of the Russian invasion of Ukraine on European system integration that is dependent on trade in fossils fuels. The paper begins by a backwards glance at how the Soviet Union disintegrated to become Putin’s Russia, via Gorbachev’s attempts at reforming the basis for social integration (Brown, 1997). It contrasts the social integration of Russia with that of the Western democracies. All of this discussion is preparatory to a consideration of Putin’s paradoxes in invading Ukraine and how the unanticipated consequences of this strategic choice point to an undermining of the basis of Putin’s power. The cost inflation and limiting of gas supplies to Europe by supply chain disruption that have been a consequence of Russia’s invasion of Ukraine provide a massive stimulus for the greening of the global economy’s energy sources, thus undermining the resource based power on which the Russian economy is founded.

An adaptive modeling method with a local choice of optimal displacement fields for finite element analysis of structures

In the standard finite element procedure, the user chooses himself which mechanical theory will be used for a given application. To this end, he relies on some rules acquired through experience or some theoretical consideration. But choosing an appropriate theory may be a difficult task when geometry, boundary conditions, loadings, and materials are complex. This paper aims to define an adaptive methodology to identify, in the context of linear static analysis, optimal finite element models from a theory choice point of view. A criterion is defined to choose, in each part of the structure, the relevant mechanical theory: solid, shell or beam. A solid mesh is defined for the whole structure while specific solid-shell or solid-beam approaches are used in shell or beam areas respectively. This avoids the construction of mid-surface or mid-axis geometries from solid ones, which is a complicated task, in particular for industrial applications. Kinematic relations between nodes are imposed to apply the displacement fields of shell or beam theories. This leads to a set of linear equations which are used for eliminating slave degrees of freedom. The methodology proposed can also be interpreted as a model size reduction method, compared to a complete solid approach. The effectiveness of this approach is demonstrated through two numerical examples, including academic cantilever structures and an industrial multilayered composite structure.

Neural basis of cognitive control signals in anterior cingulate cortex during delay discounting.

Cognitive control involves allocating cognitive effort according to internal needs and task demands and the Anterior Cingulate Cortex (ACC) is hypothesized to play a central role in this process. We investigated the neural basis of cognitive control in the ACC of rats performing an adjusting-amount delay discounting task. Decision-making in this this task can be guided by using either a lever-value tracking strategy, requiring a 'resource-based' form of cognitive effort or a lever-biased strategy requiring a 'resistance-based' form of cognitive effort. We found that ACC ensembles always tightly tracked lever value on each trial, indicative of a resource-based control signal. These signals were prevalent in the neural recordings and were influenced by the delay. A shorter delay was associated with devaluing of the immediate option and a longer delay was associated with overvaluing of the immediate option. In addition, ACC theta (6-12Hz) oscillations were observed at the choice point of rats exhibiting a resistance-based strategy. These data provide candidates of neural activity patterns in the ACC that underlie the use of 'resource-based' and 'resistance-based' cognitive effort. Furthermore, these data illustrate how strategies can be engaged under different conditions in individual subjects.

Analysis of hippocampal local field potentials by diffusion mapped delay coordinates

Spatial navigation through novel spaces and to known goal locations recruits multiple integrated structures in the mammalian brain. Within this extended network, the hippocampus enables formation and retrieval of cognitive spatial maps and contributes to decision making at choice points. Exploration and navigation to known goal locations produce synchronous activity of hippocampal neurons resulting in rhythmic oscillation events in local networks. Power of specific oscillatory frequencies and numbers of these events recorded in local field potentials correlate with distinct cognitive aspects of spatial navigation. Typically, oscillatory power in brain circuits is analyzed with Fourier transforms or short-time Fourier methods, which involve assumptions about the signal that are likely not true and fail to succinctly capture potentially informative features. To avoid such assumptions, we applied a method that combines manifold discovery techniques with dynamical systems theory, namely diffusion maps and Takens’ time-delay embedding theory, that avoids limitations seen in traditional methods. This method, called diffusion mapped delay coordinates (DMDC), when applied to hippocampal signals recorded from juvenile rats freely navigating a Y-maze, replicates some outcomes seen with standard approaches and identifies age differences in dynamic states that traditional analyses are unable to detect. Thus, DMDC may serve as a suitable complement to more traditional analyses of LFPs recorded from behaving subjects that may enhance information yield.

Interactive Plan Selection Using Linear Temporal Logic, Disjunctive Action Landmarks, and Natural Language Instruction

We present Lemming – a visualization tool for the interactive selection of plans for a given problem, allowing the user to efficiently whittle down the set of plans and select their plan(s) of choice. We demonstrate four different user experiences for this process, three of them based on the principle of using disjunctive action landmarks as guidance to cut down the set of choice points for the user, and one on the use of linear temporal logic (LTL) to impart additional constraints into the plan set using natural language (NL) instruction.

The intertemporal choice study of individual water-saving irrigation construction under three water pricing and subsidy scenarios

The world is confronted with increasing droughts exacerbated by the inefficiency of irrigation, and water-saving irrigation (WSI) holds the potential to alleviate this dilemma. Since individual farmers are important participants in WSI, it is imperative to account for their decision preferences. In addition, previous research did not consider the decision reverse in the intertemporal choice of WSI construction. Recognizing the presence of bounded rationality, particularly in terms of time preference inconsistency, a hyperbolic discounting model is constructed. The implicit subsidy, explicit subsidy, and improved explicit subsidy scenarios are simulated to analyze the decision process of individual farmers in WSI construction. The proposed methods are applied to discuss the construction of WSI within the Taocheng District, Hebei Province. The results show that: (1) The participation and stability of individual WSI construction demonstrated an increase in both the explicit subsidy and improved explicit subsidy. (2) Compared with the implicit subsidy, there was a 29.6% decrease in the number of participants who chose not to engage in WSI construction at different intertemporal choice points in the explicit subsidy scenario, and the inconsistency of choice in different intertemporal choice points decreased from 70.4% to 31.4%. (3) In the improved explicit subsidy scenario, the inconsistency of choice in different intertemporal choice points will be further reduced to 22.5%. In order to promote WSI construction for water conservation, the policy implications of the subsidy mechanism are proposed in this paper.

Discrete Event Systems Theory for Fast Stochastic Simulation via Tree Expansion

Discrete Event Systems Theory for Fast Stochastic Simulation via Tree Expansion

The omniscient speaker puzzle

The epistemicist theory aims to explain ignorance due to vagueness by semantic plasticity: the shiftiness of intensions across close possible worlds resulting from shiftiness in usage. This explanation is challenged by the Omniscient Speaker Puzzle (Sennet in Philos Stud 161(2):273–285, 2012). Suppose that an omniscient speaker, Barney, who knows all the facts about usage and how these facts determine the intensions of expressions, cooks up a scheme to stabilise the intension of a normally semantically plastic term like ‘rich’. It seems that ‘rich’ would display all the phenomena associated with vagueness without being semantically plastic, thus making the epistemicist explanation of ignorance due to vagueness insufficient. In this paper, I present a few choice points for epistemicism that arise as a result of the puzzle.

Restricting the number of drug options that can be used to treat a disease results in unsatisfactory outcomes for patients, prescribers and payers alike.

Developing new drugs is extremely expensive often costing upwards of a billion dollars to bring a drug to market1. This is driven by the studies required to demonstrate the safety of the drug and bears little relation to the cost of manufacture. Demonstration of efficacy generally requires much smaller numbers. The level of safety required is, quite rightly, stringent, and is to give confidence that unexpected side effects are unlikely to be found when the drug is released for use in the general population. If a lower level of safety was accepted, then drugs could be considerably cheaper, but at a risk. However, the study patients are selected, usually for having active disease and few other conditions to complicate response. It is estimated that only about 30% of patients seen in clinic are suitable for any particular study2 so we can’t know for sure what will happen when it is available to the other 70%. This is a weakness of the evidence base3. Drugs are licensed on a risk benefit analysis by the drug regulators eg the MHRA. More recently, driven by the expense of new drugs, in the UK, before they can be used they have been required to show cost effectiveness through a National Institute for Clinical Excellence (NICE) assessment where the cost of the improvement in quality of life needs to hit an acceptable threshold4. There is often press and political interest in these approvals. The aim of NICE is to ensure value for money and equality of access to drugs, abolishing postcode prescribing where different geographical areas have different access to drugs. However, the Clinical Commissioning Groups (CCGs) who pay for the drugs, may have their own interpretation of guidelines, and NICE approvals, which apply in their area. An example of this was a restriction on the number of higher cost drugs (HCDs Biologics and JAKi) that could be tried for RA by a substantial number of CCGs in England5,6. At a session of the BSR annual meeting in 2019 discussing what Rheumatologists do when the patient in front of them doesn’t fit the guideline for a treatment that they think will be effective, it became apparent that a substantial number of rheumatology services were restricted by their CCGs7. Those of us from unrestricted areas were surprised and could not understand the logic for this restriction. The main reason discussed was that these drugs had not been shown to be cost-effective at higher choice points. That was, of course, true but only because the studies had not been done, another weakness of the evidence base3. Lack of evidence is not evidence of lack of effect.

The experience of youth-participatory action research in a social innovation lab: A methodological and organizational approach

Based on the theory and quality criteria of Youth-Participatory Action Research (Y-PAR), youth and adult co-researchers at a social innovation lab in Ontario, Canada, have undertaken various knowledge generation and action activities for the purpose of supporting youth mental health and wellbeing among transitional-age youth (ages 16–25). We describe the methodological and organizational approach employed in this undertaking, including aspects of the social innovation model to support the action components of Y-PAR. We draw on Bradbury-Huang’s (2010) seven choice points for quality in action research to structure this collective reflection. Our experiences illustrate the tensions and opportunities arising from housing a Y-PAR project within a large health services institution. We also note how social innovation lab processes can support the emancipatory aims of participatory research. Implications for using Y-PAR in other areas are included.

Forms and transformations of empathy: Subtleties and complexities of empathic communication

ABSTRACT The role of empathic understanding and responsiveness is central to therapies anchored in self psychology and intersubjectivity theory. The process of achieving and communicating empathic understanding, however, is complex and multiply determined. Understanding on a theoretical level the rationale for employing an empathic mode of observation and response does not necessarily mean that one knows how to do so effectively. To help bridge this gap between theory and practice, the author offers a series of concrete, experience-near suggestions or principles for enhancing empathic understanding and responsiveness. Starting with Kohut, several writers have stated their belief that empathic resonance is a skill that can be developed through training and learning. The author references these previous efforts and adds to them here by defining several choice points and subtleties of how we respond that can make empathic communication more effective. These suggestions emerged from the process of training and supervising mental health professionals in all disciplines and thus are presented as a resource not only for clinicians, but also for teachers and supervisors.

Darwin's doubt or Plantinga's conviction? Some failures in Plantinga's attempt to debunk naturalistic evolution

Abstract Darwin's Doubt (DD) – a thesis according to which the probability of the human cognitive mechanism's reliability given non-guided evolution is low – is central to Plantinga's Evolutionary Argument Against Naturalism and his suggestion that the adoption of guided evolution thesis is preferable from a theory choice point of view. In this article I'll argue that there are three fundamental failures in Plantinga's argument. First, I argue that Plantinga's argument for DD is question-begging. Second, I point out that this very same argument is not in accordance with the way the evolutionary scientists usually reason. And finally I argue that the replacement of non-guided by guided evolution violates some reasonable belief-revision procedures in the history of science.

Analysis of Axon Guidance in the Drosophila Embryo.

The establishment of neural connectivity is a major part of neural development. The central nervous system (CNS) midline is the most characterized axon guidance choice point, and work in Drosophila has played a pivotal role in understanding the molecular mechanisms responsible. Axons respond to attractive cues such as Netrin via the Frazzled receptor, and repulsive cues such as Slit via Robo receptors. Both signals are expressed at the CNS midline, affect pioneer axons, and have dramatic effects on the axon scaffold as a whole. Here, we focus on previous research analyzing classic mutants in the Slit/Robo pathway, which can readily be detected with a dissecting microscope. We also discuss analyzing these mutants in a teaching lab situation. The combination of sophisticated genetics and reliable axonal markers in Drosophila allows phenotypic analysis to be performed at the single-cell level. The elaborate architecture of neurons is very sensitive to disruption by genetic mutations, allowing the effects of novel mutations to be easily detected and assessed.
