An A(i)lien Embassy: AI and Interspecies Communication

There is more than just human intelligence out there, and we must now get to grips with the end of human uniqueness. Our accelerating dexterity with biology of all sorts, digital software and hardware, pharmacology and a myriad other interventionist or evolutionary technologies is leading to the design of architectures/bodies/ systems that are fundamentally intelligently entangled. Harvard Graduate School of Design's Andrew Witt explains this ongoing synthesis and its cultural and social ramifications for today and deeper into tomorrow.

Darwin's legacy to comparative psychology and ethology.

Charles Darwin made numerous seminal contributions to the study of animal behavior over his long career. This essay places these contributions in the context of Darwin's life, showing his long-standing interest in psychological and behavioral issues encompassing all species, including humans. Ten areas are highlighted: natural history; communication; sexual selection and courtship; comparative cognition; emotion; instinct and behavioral development; inheritance of behavior; phylogeny of behavior; sociobiology and behavioral ecology; and applied animal behavior, animal welfare, and conservation. Several newer emphases that Darwin anticipated are briefly discussed. Darwin, while not always correct by current standards, crucially aided the process of firmly embedding psychological phenomena in a naturalistic scientific ethos.

A Digital Breeder for Designing Cities

The idea that inspired designs mirror processes of biological evolution is fast gaining ground as we learn more about how complex systems such as cities function. Michael Batty illustrates how cities can now be grown in ‘digital laboratories’ and, by imposing realistic constraints on their form, begin to breed ‘good designs’ that emerge from continual feedbacks that reinforce the best and iron out the worst.

Darwin’s eclipse concerned function versus mechanism.

Comments on a article by Dewsbury (February–March 2009) (see record 2009-01602-013) in which he stated, “Darwin provided a viable mechanism for evolutionary change, natural selection” (p. 67). Although this view is consistent with the modern synthesis, the author argues that (a) the natural selection “mechanism” provided by Darwin was not initially accepted by scientists because (b) natural selection is a functional explanation, and functional explanations are always incomplete because they describe how things work but not why they work; that is, they lack mechanism information. This explanatory deficiency led to what Bowler (1983), uncited by Dewsbury (2009), described (in a book of the same name) as “The eclipse of Darwinism,” the initial rejection of natural selection by most scientists. The importance of the distinction the author is making between functional explanations and mechanism information for the future of psychology is that efforts to advance psychological science by clarifying causal mechanisms must first understand how mechanism explanations differ from functional explanations.

Multilevel analysis of classical conditioning in a behaving real world artifact

The explanation of behavior requires a multilevel approach taking into account the properties of the nervous system, the phenotype (e.g., body structure) and the environment. In this paper we present an illustration of such an approach, synthetic neural modeling. We will analyse the behavior of Darwin IV, which is comprised of a real world artifact (NOMAD) and a simulated nervous system, during a block sorting task. In this study we focus on the behavioral implications of different rules governing synaptic plasticity. More specifically the concept of value-dependent learning and the role of diffuse ascending systems will be addressed. Some properties of value-dependent learning will be demonstrated by comparing it to two simulated mechanisms for synaptic change derived from Hebbian principles. Differences in performance are explained in terms of differences in the mechanisms governing the potentiation and depression of synaptic strength. The present results form a small part of a larger project focused on understanding the brain mechanism involved in classical conditioning.
