Past research has identified a variety of factors that influence cognitive processing of artifact concepts, but few experiments tested possible interactive patterns among these factors. Using a natural language depiction based free naming task, we explored how an object's function and its history (information about how an object was formed by natural force) interact to affect categorization judgment in a 2×2 betweensubjects experiment (N = 169). The study had two key findings: (i) Without presenting an object's function, presenting the history of its natural formation increased subjects' tendency to name the object under the "natural" domain and decreased their tendency to name it under the "artifact" domain; (ii) once we presented the depiction of an object's function, the effect of history presentation on categorization disappeared:Subjects in both conditions strongly preferred naming objects as artifacts. In summary, presenting depiction of an object's function inhibited the effect of history on object categorization. Current findings suggest that an object's function plays a fundamental role in the cognitive processing of artifact concepts.
Cognition and emotion have long been thought of as independent systems. However, recent research in the cognitive and neurobiological sciences has shown that the relationship between cognition and emotion is more interdependent than separate. Based on evidence from behavioral and neuroscientific research, researchers have realized that it is necessary to propose a new conceptual framework to describe the relationship between cognition and emotion. In this article, recent research from behavioral, neuroscientific and developmental research on the interaction between cognition and emotion is summarized, and how the interaction of cognition and emotion might affect computer science and artificial intelligence is discussed. It especially focuses on the implications for affective computing.
