In a seminal, often-cited and often-misunderstood article, Pascual-Leone (1970) proposed his view of a domain-general, capacity-limited attentional resource (M capacity) as a main factor of cognitive development and intelligence, and presented the Compound Stimuli Visual Information (CSVI) task, along with its Bose-Einstein (B-E) performance model, as a method to assess M capacity. Some aspects of the CSVI and its B-E model were questioned: long stimulus exposure could produce capacity over-estimates (Cowan, 2001); the assumptions on how many times a participant attends to a stimulus could be unwarranted; it would be desirable to assess the fit of B-E distributions with current methods, more refined than those used in the Seventies. This study re-examines the validity of the B-E model of the CSVI task, and its assumptions.

Abstract
In a seminal, often-cited and often-misunderstood article, Pascual-Leone (1970) proposed his view of a domain-general, capacity-limited attentional resource (M capacity) as a main factor of cognitive development and intelligence, and presented the Compound Stimuli Visual Information (CSVI) task, along with its Bose-Einstein (B-E) performance model, as a method to assess M capacity. Some aspects of the CSVI and its B-E model were questioned: long stimulus exposure could produce capacity over-estimates (Cowan, 2001); the assumptions on how many times a participant attends to a stimulus could be unwarranted; it would be desirable to assess the fit of B-E distributions with current methods, more refined than those used in the Seventies. This study re-examines the validity of the B-E model of the CSVI task, and its assumptions.
