Cognitive aspects of interactive technology use: From computers to smart objects and autonomous agents

That is the title of a recent Frontiers ebook located here. This would make an excellent discussion topic as it’s pretty much the sort of things we’ve been investigating.  We are Borg. The blurb from the link follows:

Although several researchers have questioned the idea that human technology use is rooted in unique “superior” cognitive skills, it still appears that only humans are capable of producing and interacting with complex technologies. Different paradigms and cognitive models of “human-computer interaction” have been proposed in recent years to ground the development of novel devices and account for how humans integrate them in their daily life.

Psychology has been involved under numerous accounts to explain how humans interact with technology, as well as to design technological instruments tailored to human cognitive needs. Indeed, the current technological advancements in fields like wearable and ubiquitous computing, virtual reality, robotics and artificial intelligence give the opportunity to deepen, explore, and even rethink the theoretical psychological foundations of human technology use.

The miniaturization of sensors and effectors, their environmental dissemination and the subsequent disappearance of traditional human-computer interfaces are changing the ways in which we interact not only with digital technologies, but with traditional tools as well. More and more entities can now be provided with embedded computational and interactive capabilities, modifying the affordances commonly associated with everyday objects (e.g., mobile phones, watches become “smart watches”).

This is paralleled by novel frameworks within which to understand technology. A growing number of approaches view technology use as resting on four legs, namely cognition, body, tool, and context (of course including social, cultural, and other issues). The idea is that only by viewing how these notions interact and co-determine each other can we understand what makes the human invention, adoption, and use of technology so peculiar.

Consider for example how advanced artificial prostheses are expanding the human capabilities, at the same time yielding a reconsideration of how we incorporate tools into our body schema and how cognition relates to and interacts with bodily features and processes. Then, of course, the new mind/body-with-prostheses participates in physical, cultural, and social contexts which in their turn affect how people consider and use them. Analogously, technologies for “augmenting the human mind”, such as computational instruments for enhancing attention, improving learning, and quantifying mental activities, impact on cognition and metacognition, and how we conceptualize our self.

Conversely, while virtual environments and augmented realities likely change how we experience and perceive what we consider reality, robots and autonomous agents make it relevant to explore how we anthropomorphize artificial entities and how we socially interact with them.

All these theoretical changes then back-influence our view of more traditional technologies. In the end, even a Paleolithic chopper both required a special kind of mind and at the same time modified it, the users’ bodily schema, or the way in which they participated in their sociocultural contexts.

Technological changes thus inspire a renewed discussion of the cognitive abilities that are commonly associated with technology use, like causal and abductive thought and reasoning, executive control, mindreading and metacognition, communication and language, social cognition, learning and teaching, both in relation to more traditional tools and complex interactive technologies.

The current Research Topic welcomes submissions focused on theoretical, empirical, and methodological issues as well as reflections and critiques concerning how humans create, interact, and account for technology from a variety of perspectives, from cognitive psychology, evolutionary psychology, constructivism, phenomenology, ecological psychology, social psychology, neuroscience, human-computer interaction, and artificial intelligence.

Relevant topics include but are not limited to:
– Distributed cognition in interactive environments
– Social cognition and computer-mediated communication
– Theoretical and empirical investigation of embodiment and technology
– Affordances of “traditional objects” and technological devices
– Theory of mind and social interactions with intelligent agents and robots
– Cognitive models for designing, interacting with, or evaluating technology
– Empirical studies on human-technology interaction
– Evolutionary accounts of human tool use
– Differences between animal and human tool use
– Methodological issues and opportunities in human-technology interaction

Neurocapitalism: Technological Mediation and Vanishing Lines

Open access book by Giorgio Griziotti is here. Technical book for you techies. The blurb:

“Technological change is ridden with conflicts, bifurcations and unexpected developments. Neurocapitalism takes us on an extraordinarily original journey through the effects that cutting-edge technology has on cultural, anthropological, socio-economic and political dynamics. Today, neurocapitalism shapes the technological production of the commons, transforming them into tools for commercialization, automatic control, and crisis management. But all is not lost: in highlighting the growing role of General Intellect’s autonomous and cooperative production through the development of the commons and alternative and antagonistic uses of new technologies, Giorgio Griziotti proposes new ideas for the organization of the multitudes of the new millennium.”

The Singularity is Near: When Humans Transcend Biology

Kurzweil builds and supports a persuasive vision of the emergence of a human-level engineered intelligence in the early-to-mid twenty-first century. In his own words,

With the reverse engineering of the human brain we will be able to apply the parallel, self-organizing, chaotic algorithms of  human intelligence to enormously powerful computational substrates. This intelligence will then be in a position to improve its own design, both hardware and software,  in a rapidly accelerating iterative process.

In Kurzweil's view, we must and will ensure we evade obsolescence by integrating emerging metabolic and cognitive technologies into our bodies and brains. Through self-augmentation with neurotechnological prostheses, the locus of human cognition and identity will gradually (but faster than we'll expect, due to exponential technological advancements) shift from the evolved substrate (the organic body) to the engineered substrate, ultimately freeing the human mind to develop along technology's exponential curve rather than evolution's much flatter trajectory.

The book is extensively noted and indexed, making the deep-diving reader's work a bit easier.

Prosthetic memory system successful in humans

“This is the first time scientists have been able to identify a patient’s own brain cell code or pattern for memory and, in essence, ‘write in’ that code to make existing memory work better, an important first step in potentially restoring memory loss”

We showed that we could tap into a patient’s own memory content, reinforce it and feed it back to the patient,” Hampson said. “Even when a person’s memory is impaired, it is possible to identify the neural firing patterns that indicate correct memory formation and separate them from the patterns that are incorrect. We can then feed in the correct patterns to assist the patient’s brain in accurately forming new memories, not as a replacement for innate memory function, but as a boost to it.”


Algorithm brings whole-brain simulation within reach

An improvement to the Neural Simulation Tool (NEST) algorithm, the primary tool of the Human Brain Project, expanded the scope of brain neural data management (for simulations) from the current 1% of discrete neurons (about the number in the cerebellum) to 10%. The NEST algorithm can scale to store 100% of BCI-derived or simulated neural data within near-term reach as supercomputing capacity increases. The algorithm achieves its massive efficiency boost by eliminating the need to explicitly store as much data about each neuron’s state.

Abstract of Extremely Scalable Spiking Neuronal Network Simulation Code: From Laptops to Exascale Computers

State-of-the-art software tools for neuronal network simulations scale to the largest computing systems available today and enable investigations of large-scale networks of up to 10 % of the human cortex at a resolution of individual neurons and synapses. Due to an upper limit on the number of incoming connections of a single neuron, network connectivity becomes extremely sparse at this scale. To manage computational costs, simulation software ultimately targeting the brain scale needs to fully exploit this sparsity. Here we present a two-tier connection infrastructure and a framework for directed communication among compute nodes accounting for the sparsity of brain-scale networks. We demonstrate the feasibility of this approach by implementing the technology in the NEST simulation code and we investigate its performance in different scaling scenarios of typical network simulations. Our results show that the new data structures and communication scheme prepare the simulation kernel for post-petascale high-performance computing facilities without sacrificing performance in smaller systems.


Recording data from one million neurons in real time

Given the human brain’s approximately 80 billion neurons, it would take tens of thousands of these devices to record a substantial volume of neuron-level activities. Still, this is a remarkable achievement.

The system would simultaneously acquire data from more than 1 million neurons in real time. It would convert the spike data (using bit encoding) and send it via an effective communication format for processing and storage on conventional computer systems. It would also provide feedback to a subject in under 25 milliseconds — stimulating up to 100,000 neurons.

Monitoring large areas of the brain in real time. Applications of this new design include basic research, clinical diagnosis, and treatment. It would be especially useful for future implantable, bidirectional BMIs and BCIs, which are used to communicate complex data between neurons and computers. This would include monitoring large areas of the brain in paralyzed patients, revealing an imminent epileptic seizure, and providing real-time feedback control to robotic arms used by quadriplegics and others.
