Excerpt: In 1995, the Leo Apostel Centre in Brussels, Belgium, organised an international conference called “Einstein meets Magritte”. Nobel prize winner Ilya Prigogine held the opening lecture at the conference, and Heinz von Foerster’s lecture was scheduled last… Heinz von Foerster was enchanted by the conference theme and – in the spirit of surrealist Belgian painter René Magritte – had chosen an appropriate title for his talk: “Ceci n’est pas Albert Einstein”. … [H]e was delighted to grant the organisers the following interview, in which he tells us about an even longer journey – that of his remarkable life and scientific career.

Purpose: Attention is drawn to a principle of “significance feedback” in neural nets that was devised in the encouraging ambience of the Biological Computer Laboratory and is arguably fundamental to much of the subsequent practical application of artificial neural nets. Design/methodology/approach – The background against which the innovation was made is reviewed, as well as subsequent developments. It is emphasised that Heinz von Foerster and BCL made important contributions prior to their focus on second-order cybernetics. Findings: The version of “significance feedback” denoted by “backpropagation of error” has found numerous applications, but in a restricted field, and the relevance to biology is uncertain. Practical implications: Ways in which the principle might be extended are discussed, including attention to structural changes in networks, and extension of the field of application to include conceptual processing. Originality/value – The original work was 40 years ago, but indications are given of questions that are still unanswered and avenues yet to be explored, some of them indicated by reference to intelligence as “fractal.”

Key words: cybernetics, neural nets, learning.

Purpose: An attempt was made to establish a link between brief therapy a’ la MRI and Heinz von Foerster’s view of how we might conceive of and live in the world of our creation, at least in a social sense. Design/methodology/approach – The author relates how her encounter with Heinz von Foerster coincided with and further developed a way of thinking about and doing therapy which she found at the Mental Research Institute (MRI) in Palo Alto, California. She tries to show how Heinz the person has had a lasting effect on the way she conceives of and tries to conduct Brief Therapy a’ la MRI. Findings: She finds that using Heinz’s metaphor of dancing with the world quite useful in the elucidation of what therapy might be all about: how it might, metaphorically speaking, simply be about engaging a client or clients by dancing with them, allowing for the mutual creation of a new possibility. Originality/value – This paper was written to commemorate Heinz and for therapists in search of a therapeutic stance.

Excerpt: Recent experimental work on imitation in infancy has challenged Piaget’s theory and timetable. Two aspects of Piaget’s work have been criticized: his contention that imitation of invisible gestures (i.e., gestures the imitator cannot see when he or she performs them) could not occur until the third quarter of the first year, and his contention that deferred imitation of novel sequences of actions could not occur until the beginning of the second year. The critics have marshalled empirical research that they interpret as showing invisible imitation in the neonatal period and deferred imitation at 6–9 months. This chapter argues that in both areas the empirical criticism of Piaget is not well founded. It removes a source of support for theories that attribute mental representation to young infants. In turn, it provides support for Piagetian theories that see mental representation as evolving gradually in the course of the first year. The chapter starts with a brief summary of Piaget’s theory to provide a context for his work on imitation. This summary is followed by an examination of the work on invisible imitation and deferred imitation.

In this paper, the perspective of situated cognition, which gave rise both to the pragmatic theories and the so-called semantic theories of learning and has probably become the most representative standpoint of constructivism, is examined. We consider the claim of situated cognition to provide alternative explanations of the learning phenomenon to those of psychology and, especially, to those of the symbolic perspective, currently predominant in cognitive psychology. The level of analysis of situated cognition (i.e., global interactive systems) is considered an inappropriate approach to the problem of learning. From our analysis, it is concluded that the pragmatic theories and the so-called semantic theories of learning which originated in situated cognition can hardly be considered alternatives to the psychological learning theories, and they are unlikely to add anything of interest to the learning theory or to contribute to the improvement of our knowledge about the learning phenomenon.

Sensory substitution constitutes an interesting domain of study to consider the philosopher’s classical question of distal attribution: how we can distinguish between a sensation and the perception of an object that causes this sensation. We tested the hypothesis that distal attribution consists of three distinct components: an object, a perceptual space, and a coupling between subjects’ movements and stimulation. We equipped sixty participants with a visual-to-auditory substitution device, without any information about it. The device converts the video stream produced by a head-mounted camera into a sound stream. We investigated several experimental conditions: the existence or not of a correlation between movements and resulting stimulation, the direct or indirect manipulation of an object, and the presence of a background environment. Participants were asked to describe their impressions by rating their experiences in terms of seven possible “scenarios”. These scenarios were carefully chosen to distinguish the degree to which the participants attributed their sensations to a distal cause. Participants rated the scenarios both before and after they were given the possibility to interrupt the stimulation with an obstacle. We were interested in several questions. Did participants extract laws of co-variation between their movements and resulting stimulation? Did they deduce the existence of a perceptual space originating from this coupling? Did they individuate objects that caused the sensations? Whatever the experimental conditions, participants were able to establish that there was a link between their movements and the resulting auditory stimulation. Detection of the existence of a coupling was more frequent than the inferences of distal space and object.

Increasing evidence suggests that mundane knowledge about objects, people, and events is grounded in the brain’s modality-specific systems. The modality-specific representations that become active to represent these entities in actual experience are later used to simulate them in their absence. In particular, simulations of perception, action, and mental states often appear to underlie the representation of knowledge, making it embodied and situated. Findings that support this conclusion are briefly reviewed from cognitive psychology, social psychology, and cognitive neuroscience. A similar representational process may underlie religious knowledge. In support of this conjecture, embodied knowledge appears central to three aspects of religious experience: religious visions, religious beliefs, and religious rituals. In religious visions, the process of simulation offers a natural account of how these experiences are produced. In religious beliefs, knowledge about the body and the environment are typically central in religious frameworks, and are likely to affect the perception of daily experience. In religious rituals, embodiments appear central to conveying religious ideas metaphorically and to establishing them in memory. To the extent that religious knowledge is like non-religious knowledge, embodiment is likely to play central roles.

Können Pädagogik und Erwachsenenbildung ohne Ethik auskommen? Offenbar nein: Selbst da, wo sie vermeintlich ethikferne Theorien rezipieren, sind Transformationsmuster am Werk, die ethische Aufladungen vornehmen. Zu diesem Ergebnis kommt der Autor in der empirischen Analyse eines ganz besonderen Datenmaterials: des Texts der “Konstruktivistischen Erwachsenenbildung” von R. Arnold und H. Siebert. Ein prominenter Musterfall für die Rezeptionspraxis im Bereich von Pädagogik/Erwachsenenbildung – und damit auch für die Vergewisserung über deren Verhältnis zu Bezugswissenschaften.
