You briefly walk around the room, finding out the name of each person. Then, half an hour later, you must go around the room and identify all 300 people by name. That’s I impossible, you might think. No-one could memorise that many people’s names in such a short space of time. Well, don’t tell that to Kerry Domann, an Australian entertainer who regularly amazes dinner func- tions with his ability to recall the names of up to 300 audience members just minutes after meeting them for the first time. Performing under the stage name ‘The Amazing Nigel’, Kerry is in demand around the country as an after-dinner speaker who enter- tains with a mix of comedy and magic.

  • Remembering Müller and Pilzecker
    PERSPECTIVE Hilde A. Lechner,1 100 Years of Consolidation— Larry R. Squire,2 and John H. Byrne Remembering Mu¨ller and Pilzecker 1W.M. Keck Center for the Neurobiology of Learning and Memory Department of Neurobiology and Anatomy University of Texas–Houston Medical School Houston, Texas 77030 USA 2Veterans Affairs Medical Center, San Diego and Departments of Psychiatry, Neurosciences, and Psychology University of California, San Diego La Jolla, California 92093 USA Introduction The origin of the concept of memory consolidation and the introduction of the term “consolidirung” (consolidation) to the modern science of memory are generally credited to Georg Elias Mu¨ller (1850–1934), professor at the University of Göttingen, Germany, and his student Alfons Pilzecker. Their seminal monograph “Experimentelle Beitra¨ge zur Lehre vom Geda¨chtnis” (Experimental Contributions to the Science of Memory), published in 1900, proposed that learning does not induce instantaneous, permanent memories but that memory takes time to be fixed (or consolidated). Consequently, memory remains vulnerable to disruption for a period of time after learning. Georg Mu¨ller was among the founders of experimental psychology. Inspired by the work of Gustav Fechner (1801–1887), Wilhelm Wundt (1832–1920), and Herman Ebbinghaus (1859–1909),1 he was an early advocate of the view that mental function results from the action of matter, and that learning and memory should thus exhibit lawful properties. In their 300-page monograph, Mu¨ller and Pilzecker reported 40 experiments, carried out between 1892 and 1900, which were designed to identify the laws that govern memory formation and retrieval. Although Mu¨ller and Pilzecker have been frequently acknowledged for introducing the concept of memory consolidation,2 their monograph has not been translated and knowledge of their methods and experimental findings has faded with the passing of almost a century.

  • Dissociation Related to Subjective Memory Fragmentation and Intrusions but Not to Objective Memory Disturbances
    ARTICLE IN PRESS Journal of Behavior Therapy and Experimental Psychiatry 36 (2005) 43–59 www.elsevier.com/locate/jbtep Dissociation related to subjective memory fragmentation and intrusions but not to objective memory disturbances Merel Kindta,Ã, Marcel Van den Houtb, Nicole Buckb aDepartment of Clinical Psychology, University of Amsterdam, Roetersstraat 15, 1018 WB Amsterdam, The Netherlands bDepartment of Medical, Clinical and Experimental Psychology, Maastricht University, The Netherlands Abstract The present study was a replication of Kindt and Van den Hout (Behaviour Research and Therapy 41 (2003) 167) with several methodological adaptations. Two experiments were designed to test whether state dissociation is related to objective memory disturbances, or whether dissociation is confined to the realm of subjective experience. High trait dissociative participants (Nexp:1 ¼ 25; Nexp:2 ¼ 25) and low trait dissociative participants (Nexp:1 ¼ 25; Nexp:2 ¼ 25) were selected from normal samples (Nexp:1 ¼ 372; Nexp:2 ¼ 341) on basis of scores on the Dissociative Experience Scale (DES). Participants watched an extremely aversive film, after which state dissociation was measured by the Peri-traumatic Dissociative Experience Questionnaire (PDEQ). Memory disturbances were assessed 4h later (Exp. 1) or 1 week later (Exp. 2). Objective memory disturbances were assessed by a sequential memory task, items tapping perceptual representations (Exp. 1), or an open question with respect to the remembrance of the film (Exp. 2). Subjective memory disturbances were measured by means of visual analogue scales assessing fragmentation and intrusions. The two experiments provided a fairly exact replication of an earlier experiment (Behaviour Research and Therapy 41 (2003) ÃCorresponding author.

  • How Big Is Human Memory, Or on Being Just Useful Enough
    Downloaded from learnmem.cshlp.org on September 29, 2021 - Published by Cold Spring Harbor Laboratory Press REVIEW Yadin Dudai How Big Is Human Memory, Department of Neur0bi010gy or On Being Just Useful Enough The Weizmann Institute of Science Reh0v0t 76100 Israel We are, in many respects, what we remember. But how much do we do? So far, science has provided only a very partial answer to this riddle. The magical number seven, plus or minus two, seems to constrain the capacity of our immediate memory (Miller 1956). But surely its constraints dissipate when memories settle in long-term stores. Yet how big are these stores? If we combine all of our factual knowledge and personal reminiscence, childhood scenes and memories of the past day, intimate experiences and professional expertisemhow many items are there, that, combined together, mold us into unique individuals? The answer is not simple, and neither is the question. For example, what is an item in long-term memory? And how can we measure it, being sure that we unveil memory capacity and not merely the occasional ability to tap it? Such theoretical and practical difficulties, no doubt, have contributed to the fact that the capacity of human memory is still an enigma. Yet, despite the inherent and undeniable complexities, the issue deserves to be retrieved, once in a while, from the oblivions of the collective memory of the scientific community. (For a selection of earlier discussions of the size of human long-term memory, see Galton 1879; Landauer 1986; Crovitz et al. 1991.) Folk Psychology and When confronted with the issue, many tend to provide an intuitive Early Views estimate of the size of their memory, based either on belief or introspection or both.
