A clinical vignette is used as the starting point for an exploration of Bion's notion of a contact-barrier, which "separates mental phenomena into two groups one of which performs the functions of consciousness and the other the functions of unconsciousness" (Bion, 1962a, p. 22), and its relation to Freud's drive theory. Bion's concept is compared to Freud's (1950[1895]) description of the 'contact-barrier' in the Project for a scientific psychology. Through this comparison, light is shed on various aspects of Bion's metapsychology, especially on the notion of 'beta-elements', described by Bion in quantitative/energetic terms as 'accretions of stimuli'. The processing of beta-elements through the function of the contact-barrier is understood as an elaboration of Freud's notion of the 'binding' of the drives, with the difference that beta-elements encompass 'unprocessed' external stimuli as well as impulses arising from within. The 'beta-element' and the 'drives' are both understood as concepts that delimit what is knowable in the psyche. Further clinical material is presented to illustrate the author's argument that Bion's contact-barrier and related concepts (alpha function, containment) should be understood with reference to the economic/energetic aspect of Freud's metapsychology.
一个临床案例被用作探索比昂的接触屏障概念的起点，该概念“将心理现象分为两组，一组执行意识功能，另一组执行无意识功能”（比昂，1962a，第22页），以及它与弗洛伊德驱力理论的关系。比昂的概念与弗洛伊德（1950[1895]）在《科学心理学大纲》中对“接触屏障”的描述进行了比较。通过这种比较，比昂的元心理学的各个方面得以阐明，尤其是“β元素”的概念，比昂用定量/能量术语将其描述为“刺激的累积”。通过接触屏障的功能对β元素的处理被理解为对弗洛伊德驱力“约束”概念的一种细化，不同之处在于β元素既包括“未处理的”外部刺激，也包括内部产生的冲动。“β元素”和“驱力”都被理解为界定心理中可知内容的概念。还提供了更多临床材料，以说明作者的观点，即比昂的接触屏障及相关概念（α功能、容纳）应参照弗洛伊德元心理学的经济/能量方面来理解。
