The aim of this work is to bring out the historiographical categorization and periodization of the studies on dreams between the late 19th and early 20th century. The study is divided into different stages: bibliographic research, content analysis, and statistical analysis. For bibliographic research, we selected 315 studies written between 1872 and 1940 and published in PsycInfo, the database of the American Psychological Association. We assigned each work to specific categories (psychological and physical disorders, general psychology, psychoanalytical theory, physiological psychology, and other categories). Each of these works underwent content analysis, whereby we highlighted the main model used by the different authors in the dreaming studies. Statistical analysis examined the relation between model and category. The methodology used integrated quantitative and qualitative perspectives for a better interpretation of the data. This historical research gives a new contribution to contemporary studies that have neglected the study of dreams in past decades. In fact, the conclusion of this study highlights the attention of general psychology to the study of dreams, the important role of psychological models as the main research approach in this field, and the premature attention to the dream with the physiological and psychological model, in an integrated perspective.

19 世纪末 20 世纪初对梦的实验和系统研究的实证研究和文献综述：一般心理学的重要作用。

这项工作的目的是提出 19 世纪末至 20 世纪初对梦的研究的历史分类和分期。该研究分为不同的阶段：书目研究、内容分析和统计分析。对于书目研究，我们选择了 1872 年至 1940 年间撰写并发表在美国心理学会数据库 PsycInfo 上的 315 项研究。我们将每项工作分配到特定类别（心理和身体障碍、一般心理学、精神分析理论、生理心理学和其他类别）。这些作品中的每一个都经过了内容分析，我们强调了不同作者在做梦研究中使用的主要模型。统计分析检查了模型和类别之间的关系。该方法使用综合的定量和定性观点来更好地解释数据。这项历史研究为过去几十年忽视梦研究的当代研究做出了新的贡献。事实上，本研究的结论突出了一般心理学对梦研究的关注，心理学模型作为该领域主要研究方法的重要作用，以及对梦的过早关注与生理和心理模型，在综合观点。
