Language and Cognition Interaction Neural Mechanisms
How language and cognition interact in thinking? Is language just used for communication of completed thoughts, or is it fundamental for thinking? Existing approaches have not led to a computational theory. We develop a hypothesis that language and cognition are two separate but closely interacting mechanisms. Language accumulates cultural wisdom; cognition develops mental representations modeling surrounding world and adapts cultural knowledge to concrete circumstances of life. Language is acquired from surrounding language “ready-made” and therefore can be acquired early in life. This early acquisition of language in childhood encompasses the entire hierarchy from sounds to words, to phrases, and to highest concepts existing in culture. Cognition is developed from experience. Yet cognition cannot be acquired from experience alone; language is a necessary intermediary, a “teacher.” A mathematical model is developed; it overcomes previous difficulties and leads to a computational theory. This model is consistent with Arbib's “language prewired brain” built on top of mirror neuron system. It models recent neuroimaging data about cognition, remaining unnoticed by other theories. A number of properties of language and cognition are explained, which previously seemed mysterious, including influence of language grammar on cultural evolution, which may explain specifics of English and Arabic cultures
Multimodal Grounding for Language Processing
This survey discusses how recent developments in multimodal processing
facilitate conceptual grounding of language. We categorize the information flow
in multimodal processing with respect to cognitive models of human information
processing and analyze different methods for combining multimodal
representations. Based on this methodological inventory, we discuss the benefit
of multimodal grounding for a variety of language processing tasks and the
challenges that arise. We particularly focus on multimodal grounding of verbs
which play a crucial role for the compositional power of language.Comment: The paper has been published in the Proceedings of the 27 Conference

Resonant Neural Dynamics of Speech Perception
What is the neural representation of a speech code as it evolves in time? How do listeners integrate temporally distributed phonemic information across hundreds of milliseconds, even backwards in time, into coherent representations of syllables and words? What sorts of brain mechanisms encode the correct temporal order, despite such backwards effects, during speech perception? How does the brain extract rate-invariant properties of variable-rate speech? This article describes an emerging neural model that suggests answers to these questions, while quantitatively simulating challenging data about audition, speech and word recognition. This model includes bottom-up filtering, horizontal competitive, and top-down attentional interactions between a working memory for short-term storage of phonetic items and a list categorization network for grouping sequences of items. The conscious speech and word recognition code is suggested to be a resonant wave of activation across such a network, and a percept of silence is proposed to be a temporal discontinuity in the rate with which such a resonant wave evolves. Properties of these resonant waves can be traced to the brain mechanisms whereby auditory, speech, and language representations are learned in a stable way through time. Because resonances are proposed to control stable learning, the model is called an Adaptive Resonance

Cognitive Representation Learning of Self-Media Online Article Quality
The automatic quality assessment of self-media online articles is an urgent
and new issue, which is of great value to the online recommendation and search.
Different from traditional and well-formed articles, self-media online articles
are mainly created by users, which have the appearance characteristics of
different text levels and multi-modal hybrid editing, along with the potential
characteristics of diverse content, different styles, large semantic spans and
good interactive experience requirements. To solve these challenges, we
establish a joint model CoQAN in combination with the layout organization,
writing characteristics and text semantics, designing different representation
learning subnetworks, especially for the feature learning process and
interactive reading habits on mobile terminals. It is more consistent with the
cognitive style of expressing an expert's evaluation of articles. We have also
constructed a large scale real-world assessment dataset. Extensive experimental
results show that the proposed framework significantly outperforms
state-of-the-art methods, and effectively learns and integrates different
factors of the online article quality assessment.Comment: Accepted at the Proceedings of the 28th ACM International Conference

Modelling the Developing Mind: From Structure to Change
This paper presents a theory of cognitive change. The theory assumes that the fundamental causes of cognitive change reside in the architecture of mind. Thus, the architecture of mind as specified by the theory is described first. It is assumed that the mind is a three-level universe involving (1) a processing system that constrains processing potentials, (2) a set of specialized capacity systems that guide understanding of different reality and knowledge domains, and (3) a hypecognitive system that monitors and controls the functioning of all other systems. The paper then specifies the types of change that may occur in cognitive development (changes within the levels of mind, changes in the relations between structures across levels, changes in the efficiency of a structure) and a series of general (e.g., metarepresentation) and more specific mechanisms (e.g., bridging, interweaving, and fusion) that bring the changes about. It is argued that different types of change require different mechanisms. Finally, a general model of the nature of cognitive development is offered. The relations between the theory proposed in the paper and other theories and research in cognitive development and cognitive neuroscience is discussed throughout the paper
Act-Based Statements Effect on Bartending Tips
Acceptance and Commitment Therapy (ACT) is a behaviorally-based intervention that emphasizes psychological processes related to mindfulness, values, committed actions towards values, defusion from troubling thoughts, and acceptance. ACT is often used with populations who experience psychological inflexibility or stress, but not much research has been done understanding how ACT processes may affect everyday tasks within the common public or within business practices. The present study used a randomized controlled trial to determine the effect that statements related to ACT processes given while receiving a bar tending service altered the outcome tipping percentage from guests. The current research also discussed how each statement used relates back to the various components of ACT. The current study suggests a potential way to increase tips that a bartender or server can receive by providing a simple ACT-based statement to their customers while still maintaining an inviting and friendly environment for entertainment. Results of this study indicated that the use of mindfulness statements was statistically significant, t(53) = 1.68, p \u3c .098. While one of the six prepared and randomized mindfulness statements, “It’s it a nice night for a drink?” used was statistically significant in increasing tip revenue when compared to all other mindfulness statements used and the low-quality control statements used in a one-way ANOVA analysis, F(6, 48) = 1.799, p = .11. Results of this study were not significant for a t-test comparing statements and total tip value received compared to total bill amount t(5) = 0.887, p \u3c .378. Additionally, results of a two-way ANOVA comparing male and female and tip value also displayed no statistical significance F(1, 51) = 0.051, p = .82, F(1, 51) = 1.106, p = .29, with no significant interaction, F(1, 51) = 2.467, p = .12. Lastly, a two-way ANOVA comparing male and female and total tip value received compared to total bill amount displayed no significance as well F(1, 51) = 0.448, p = .50, F(1, 51) = 1.439, p = .23, with no significant interaction F(1, 51) = 0.693, p = .40. Organizational behavior management (OBM) is an area of behavior intervention ripe for ACT research. Future OBM research could extend upon by incorporating the use of ACT, or ACT related processes into everyday business models and behaviors
Attention and Anticipation in Fast Visual-Inertial Navigation
We study a Visual-Inertial Navigation (VIN) problem in which a robot needs to
estimate its state using an on-board camera and an inertial sensor, without any
prior knowledge of the external environment. We consider the case in which the
robot can allocate limited resources to VIN, due to tight computational
constraints. Therefore, we answer the following question: under limited
resources, what are the most relevant visual cues to maximize the performance
of visual-inertial navigation? Our approach has four key ingredients. First, it
is task-driven, in that the selection of the visual cues is guided by a metric
quantifying the VIN performance. Second, it exploits the notion of
anticipation, since it uses a simplified model for forward-simulation of robot
dynamics, predicting the utility of a set of visual cues over a future time
horizon. Third, it is efficient and easy to implement, since it leads to a
greedy algorithm for the selection of the most relevant visual cues. Fourth, it
provides formal performance guarantees: we leverage submodularity to prove that
the greedy selection cannot be far from the optimal (combinatorial) selection.
Simulations and real experiments on agile drones show that our approach ensures
state-of-the-art VIN performance while maintaining a lean processing time. In
the easy scenarios, our approach outperforms appearance-based feature selection
in terms of localization errors. In the most challenging scenarios, it enables
accurate visual-inertial navigation while appearance-based feature selection
fails to track robot's motion during aggressive maneuvers.Comment: 20 pages, 7 figures, 2 table
