A commentary on "From Miller's Seven to Cowan's Four in Baddeley's Working-Memory Framework with Lucas-numbers: Immediate/short-term span L₄ = 7, central working- memory capacity L₃ = 4, and a falsifiable hypothesis based on GEIER's equations - A first approach" by Stefan Geier et al.
A commentary on "From Miller's Seven to Cowan's Four in Baddeley's Working-Memory Framework with Lucas-numbers: Immediate/short-term span L₄ = 7, central working- memory capacity L₃ = 4, and a falsifiable hypothesis based on GEIER's equations - A first approach" by Stefan Geier et al. From Miller’s Seven to Cowan’s Four: A Conceptually Clarifying Lucas-Number Perspective on Short-Term and Working Memory by Stefan Geier et al.* This paper is an unusually ambitious and intellectually stimulating contribution at the intersection of experimental psychology, cognitive theory, mathematical pattern analysis and the philosophy of science. Its particular merit lies not merely in observing that the psychologically prominent numbers seven and four are Lucas numbers, but in embedding this observation within a carefully differentiated account of memory constructs. By distinguishing Miller’s classical immediate-memory span of approximately seven chunks from the more restri...
