(Re)claiming plants in comparative psychology

Up until the middle of the 19th century, some data about plant behavior could be found in books dealing with comparative psychology. The tendency gradually faded away, and the topic was almost exclusively treated in literature dealing with plant physiology. In recent years, however, there has been a revamping of psychological terminology and theorizing to describe, explain, and formulate hypotheses on the evidence that many of the sophisticated behaviors plants exhibit are an expression of cognitive competences that are generally attributed to human and nonhuman animals. In this work I shall discuss a selection of experimental studies supporting the idea that plants could be defined as cognitive agents. Experiments showing that the behavior of plants is controlled by a representation of its goal, episodic-like memory, and decision-making will be described. It is not, however, my intention to embrace any position as to whether or to what degree plants are conscious. Rather, I hope to (re)fuel the discussion within the psychological community that will point in the direction of integrating studies concerning adaptive plant behavior within the wider field of comparative psychology.
