Analogical gestures foster understanding of causal systems

چکیده
Sensitivity to the causal structure underlying phenomena is critical to expert understanding. Fostering such understanding in learners is therefore a key goal in education. We hypothesized that observing analogical gestures—which represent relational information in visuospatial format— would lead learners to notice and reason about underlying causal patterns, such as positive and negative feedback. Participants watched brief video lectures about the human body and the plant kingdom, which were delivered along with gestures representing either: 1) visuospatial details (iconic gesture condition); or 2) relational structure (analogical gesture condition). In a subsequent classification task, relative to participants who saw iconic gestures, participants who saw analogical gestures were more likely to sort the phenomena described in the videos—as well as novel phenomena—by their causal structure (e.g., positive feedback). The results suggest that analogical gestures can be harnessed to foster causal understanding.

Effects of Gesture on Analogical Problem Solving: When the Hands Lead you Astray
We investigated the role of speech-accompanying gestures in analogical problem solving. Participants attempted to solve Duncker’s (1945) Radiation Problem after reading and retelling a story that described an analogous solution in a different domain. Participants were instructed to gesture, instructed not to gesture, or given no instructions regarding gesture as they retold the story. Participa...
متن کاملAnalogical Inferences in Causal Systems
Analogical and causal reasoning theories both seek to explain patterns of inductive inference. Researchers have claimed that reasoning scenarios incorporating aspects of both analogical comparison and causal thinking necessitate a new model of inductive inference (Holyoak, Lee, & Lu, 2010; Lee & Holyoak, 2008). This paper takes an opposing position, arguing that features of analogical models ma...
متن کاملWhen Gesture Becomes Analogy
Analogy researchers do not often examine gesture, and gesture researchers do not often borrow ideas from the study of analogy. One borrowable idea from the world of analogy is the importance of distinguishing between attributes and relations. Gentner (, ) observed that some metaphors highlight attributes and others highlight relations, and called the latter analogies. Mirroring this logic, we o...
متن کاملInference processes in causal analogies
In recent papers, Lee & Holyoak (2007, 2008a, 2008b) argue that extant models of analogy fail to explain how people draw inferences from causal analogies. In the current research, we argue that structure-mapping theory sufficiently explains the analogical inferences drawn from these causal analogies, and that, contrary to L&H‘s claims, the effect inference can indeed be evaluated by a post-anal...
متن کاملAnalogical Reinforcement Learning
Research in analogical reasoning suggests that higher-order cognitive functions such as abstract reasoning, far transfer, and creativity are founded on recognizing structural similarities among relational systems. Here we integrate theories of analogy with the computational framework of reinforcement learning (RL). We propose a computational synergy between analogy and RL, in which analogical c...
