Quizplus · Accepted Answer

Fechner's "Elements of Psychophysics" (1860) and Wundt's "Contributions to the Theory of Sensory Perception" (1858-1862) are both foundational works in the field of psychology. Fechner's work is considered a seminal text in psychophysics, introducing methods to quantify the relationship between physical stimuli and the sensations and perceptions they produce. Wundt's contributions laid the groundwork for experimental psychology, leading to his establishment of the first psychology laboratory. Both works mark significant milestones in the development of psychology as a distinct scientific discipline.
