Communication involves commitment to one’s words. These words often carry multiple layers of meaning. The explicit meaning may commit the speaker to one proposition, and the implicit to another. This raises the question: to which meaning are speakers seen as committed? This study examined whether listeners process commitment to utterances’ explicit and implicit meaning independently or integratively. Across three experiments, participants were presented with communicative scenarios and corresponding outcomes (each meaning’s truth-value). Participants’ perceived commitment to each meaning (explicit or implicit) was measured through a direct commitment probe and overall trust. All three experiments demonstrated that the truth-value of the implicit content influenced perceived commitment not only to the implicit meaning, but also to the explicit, despite the latter being independently true/false. The effect was asymmetrical: the explicit truth-value influenced commitment almost exclusively to the explicit meaning. Thus, we observed an ‘implicit dominance’ that was present despite variation in presentation and stimuli. Compared to direct commitment, trust was shaped by all truth-values, indicating that trust reflects a global evaluation of the speaker, while commitment is aligned with specific communicative intentions. These findings suggest that listeners integrate different meanings when evaluating a speaker’s commitment to their words.

This article aims to understand how Eastern and Western philosophies shape the perspectives of scholars and practitioners in framing co-opetition (i.e., the coexistence of competition and cooperation) in distinctive manners and, in turn, how such distinctions shape the behavioral patterns of co-opetition. We disentangle the constructs of competition and cooperation and their coexistence as proposed by three Chinese schools of thought (i.e., Taoism, Confucianism, and Legalism) and three Western philosophers (i.e., Immanuel Kant, Georg W. F. Hegel, and Adam Smith). Based on this groundwork, we unveil four comparative philosophical logics used to address the essence of co-opetition (i.e., either/or, both/and, both/or, and either/and). In addition, we apply such East-meeting-West linkages to a typology of co-opetition strategies.

Motor adaptation is a process by which the brain gradually reduces error induced by a predictable change in the environment, e.g., pointing while wearing prism glasses. It is thought to occur via largely implicit processes, though explicit strategies are also thought to contribute. Research suggests a role of the cerebellum in the implicit aspects of motor adaptation. Using non-invasive brain stimulation, we sought to investigate the involvement of the cerebellum in implicit motor adaptation in healthy participants. Inhibition of the cerebellum was attained through repetitive transcranial magnetic stimulation (rTMS), after which participants performed a visuomotor-rotation task while using an explicit strategy. Adaptation and aftereffects of the TMS group showed no difference in behaviour compared to a Sham stimulation group, therefore this study did not provide any further evidence of a specific role of the cerebellum in implicit motor adaptation. However, our behavioral findings replicate those in the seminal study by Mazzoni and Krakauer (2006).

The term ‘metalinguistic’ is used to define the kind of ability whereby people for various purposes view language as an object. It is strongly associated with consciousness and touches on many aspects of literacy, multilingualism and language acquisition. Discussions in the research literature have generally been on specific aspects of metalinguistic knowledge: the time is ripe for a more fundamental reassessment focusing on how exactly metalinguistic ability is represented and processed on line, and how it fits in with other kinds of representation and processing. To this end, a particular theoretical perspective that takes into account contemporary research in cognitive science, the Modular Cognition Framework, will be applied with the aim of supporting further empirical investigations into this area of language ability and locating it within an integrated approach to cognition in general. Finally, the usefulness of metalinguistic knowledge will be briefly considered.

Uniformization transforms a pseudo-Poisson process with unequal intensities (leaving rates) into one with uniform intensity. Self-transitions is the price to pay. Two intensities arise when one considers an absorbing barrier of a Markov process as a body in its own right: a pair of Markov processes intertwined by an extended Chapman–Kolmogorov equation naturally arises. We show that Sauer's two-state space empathy theory handles such intertwined processes. The price of self-transitions is also avoided.

Objectives: Anosognosia for motor impairment is a complex syndrome that can manifest itself under different forms, guiding patients’ behavior and task decisions. However, current diagnostic tools tend to evaluate only more explicit aspects of anosognosia (asking the patients about their motor abilities) and fail to address more subtle features of awareness. We have developed a new assessment measure, the ECT (Errand Choice Test), where patients are asked to judge task difficulty rather than estimate their own impairment. Methods: We assessed awareness in a group of 73 unilateral left- and right-brain damaged (30 LBD and 43 RBD, respectively) patients by means of the VATAm, which explicitly requires them to evaluate their own motor abilities, and the ECT. A control group of 65 healthy volunteers was asked to perform the ECT under two conditions: Current condition (i.e., using both hands) and Simulated conditions (i.e., simulating hemiplegia). Results: A total of 27% of the patients showed different performance on the VATAm and ECT, 21% of the patients showing lack of awareness only on VATAm and 6% only on ECT. Moreover, despite the ECT identified a higher frequency of anosognosia after RBD (33.3%) than LBD (27.6%), this hemispheric asymmetry was not significant. Remarkably, anosognosic patients performed very similarly to controls in the “current condition”, suggesting that anosognosic patients’ ability to perceive the complexity of each task per se is not altered. Conclusion: Different methods may be able to tackle different aspects of awareness and the ECT proved to be able to detect less evident forms of awareness. (JINS, 2018, 24, 45–56)

There is currently some debate as to whether hippocampus mediates contextual cueing. In the present study, we examined contextual cueing in patients diagnosed with mild cognitive impairment (MCI) and healthy older adults, with the main goal of investigating the role of hippocampus in this form of learning. Amnestic MCI (aMCI) patients and healthy controls completed the contextual cueing task, in which they were asked to search for a target (a horizontal T) in an array of distractors (rotated L’s). Unbeknownst to them, the spatial arrangement of elements on some displays was repeated thus making the configuration a contextual cue to the location of the target. In contrast, the configuration for novel displays was generated randomly on each trial. The difference in response times between repeated and novel configurations served as a measure of contextual learning. aMCI patients, as a group, were able to learn spatial contextual cues as well as healthy older adults. However, better learning on this task was associated with higher hippocampal volume, particularly in right hemisphere. Furthermore, contextual cueing performance was significantly associated with hippocampal volume, even after controlling for age and MCI status. These findings support the role of the hippocampus in learning of spatial contexts, and also suggest that the contextual cueing paradigm can be useful in detecting neuropathological changes associated with the hippocampus.

The paper is devoted to the development of an efficient deterministic framework for modelling of three-dimensional rarefied gas flows on the basis of the numerical solution of the Boltzmann kinetic equation with the model collision integrals. The framework consists of a high-order accurate implicit advection scheme on arbitrary unstructured meshes, the conservative procedure for the calculation of the model collision integral and efficient implementation on parallel machines. The main application area of the suggested methods is micro-scale flows. Performance of the proposed approach is demonstrated on a rarefied gas flow through the finite-length circular pipe. The results show good accuracy of the proposed algorithm across all flow regimes and its high efficiency and excellent parallel scalability for up to 512 cores.

Twenty-eight children with autism and 33 MLD children were given two tasks tapping social understanding and a control task tapping probability understanding. For each task there was a measure of eye gaze (where children looked when anticipating the return of a story character or an object) and a verbal measure (a direct question). We found that eye gaze was better than verbal performance at differentiating children with autism from children with MLD. Children with autism did not look to the correct location in anticipation of the story character's return in the social tasks, but they did look to the correct location in the nonsocial probability task. We also found that within the autistic group, children who looked least to the correct location were rated as having the most severe autistic characteristics. Further, we found that whereas verbal performance correlated with general language ability in the autistic group, eye gaze did not. We argue that: (a) eye gaze probably taps unconscious but core insights into social behavior and as such is better than verbal measures at differentiating children with autism from mentally handicapped controls, (b) eye gaze taps either spontaneous processes of simulation or rudimentary pattern recognition, both of which are less based in language, and (c) the social understanding of children with autism is probably based mostly on verbally mediated theories whereas control children also possess more spontaneous insights indexed by eye gaze.
