The analysis of the internal consistency of the intuitive physics test disclosed an unsatisfactory coefficient. Among the 330 schoolchildren there was observed statistically significant difference between the scores of the two genders, with superior performance in boys, as well as an increment in scores in accordance with age, grade in school and type of school. The best performance occurred in the children of private school. Between the clinical group (composed of 28 high functioning autism individuals) and the control group (composed of 28 from private schoolchildren), the latter showed the best performance in the intuitive physics test as well as in the mechanical reasoning test. The psychometric properties of the test showed a low consistency index. The performance among school participants changed according to the development, which may reflect not only cognitive development but also their everyday experience and school education. Otherwise, the high functioning autists didn´t have better performance in the intuitive physics test when compared with the control group

abstract: When a rolling ball exits a spiral tube, it typically maintains its final inertial state and travels along straight line in concordance with Newton's first law of motion. Yet, most people predict that the ball will curve, a "naive physics" misconception called the curvilinear impetus (CI) bias. In the current paper, we explore the ecological hypothesis that the CI bias arises from overgeneralization of correct motion of biological agents. Previous research has established that humans curve when exiting a spiral maze, and college students believe this motion is the same for balls and humans. The current paper consists of two follow up experiments. The first experiment tested the exiting behavior of rodents from a spiral rat maze. Though there were weaknesses in design and procedures of the maze, the findings support that rats do not behave like humans who exhibit the CI bias when exiting a spiral maze. These results are consistent with the CI bias being an overgeneralization of human motion, rather than generic biological motion. The second experiment tested physics teachers on their conception of how a humans and balls behave when exiting a spiral tube. Teachers demonstrated correct knowledge of the straight trajectory of a ball, but generalized the ball's behavior to human motion. Thus physics teachers exhibit the opposite bias from college students and presume that all motion is like inanimate motion. This evidence supports that this type of naive physics inertial bias is at least partly due to participants overgeneralizing both inanimate and animate motion to be the same, perhaps in an effort to minimize cognitive reference memory load. In short, physics training appears not to eliminate the bias, but rather to simply shift it from the presumption of stereotypical animate to stereotypical inanimate behavior. / Dissertation/Thesis / M.A. Psychology 2013

Since the first studies on perceptual causality, there has been a debate about whether or not causality can be directly perceived or if reports of causality are the products of higher level memory and cognition. This dissertation directly tests the relationship between causality, animacy, and higher level cognition for events that entail one and two force interactions. Perceptual causality and animacy were reported in a recognition task where participants viewed animations of single and two force events. The events simulated: interactions that obeyed the laws of physics, interactions that reflected high frequency alternate conceptions found through a pilot study, and a parametrically varied set of angular deviations from the motions in the set that obeyed physics. Results showed that reports of perceptual causality and perceptual animacy were highly negatively correlated. Solutions that likely appeared physically plausible—such as correct physics paths and high frequency alternate conceptions—were rated as high in causality and low in animacy and highly implausible solutions—such as motions 180 degrees from the correct physics path—were rated as low in causality and high in animacy. Higher level cognition was tested through a production task where participants were asked to predict the path they believed a ball would take when acted upon by one or two forces. This task allowed novices to report their conceptions of single and two force interactions. In addition to paths that closely resembled the physically correct path, people also frequently produced paths that had inaccurate angles, that were curved, or that appeared to be determined by the larger or more recent of the two forces. The combined results suggest that higher level cognition played a role in the experience of causality and animacy in the animations, with animation paths similar to those generated during the production task rated higher in naturalness and lower in animacy than other types of paths, but that this effect was dependent on the complexity of the force interaction. Recognition task results for single force and two equal forces facing each other were not predicted by the type of path generated during the production task, but production task results did predict recognition task ratings for all other force relations tested. Different aspects of the data support each of the two sides of the debate; causality may be directly perceived in some, but not all, situations. / Psychology
