Visual impressions of active and inanimate resistance to impact from a moving object

ABSTRACT

Images of moving objects presented on computer screens may be perceived as animate or inanimate. A simple hypothesis, consistent with much research evidence, is that objects are perceived as inanimate if there is a visible external contact from another object immediately prior to the onset of motion, and as animate if that is not the case. Evidence is reported that is not consistent with that hypothesis. Objects (targets) moving on contact from another object (launcher) were perceived as actively resisting the impact of the launcher on them if the targets slowed rapidly. Rapid slowing is consistent with the laws of mechanics for objects moving in an environment that offers friction and air resistance. Despite that, ratings of inanimate motion were lower than ratings of active resistance for objects that slowed rapidly. The results are consistent with the hypothesis that there is a perceptual impression of active (animate) resistance that is evoked by the kinematic pattern of rapid slowing from an initial speed after contact from another object.     

The temporal-relevance temporal-uncertainty model of prospective duration judgment

A model aimed at explaining prospective duration judgments in real life settings (as well as in the laboratory) is presented. The model is based on the assumption that situational meaning is continuously being extracted by humans’ perceptual and cognitive information processing systems. Time is one of the important dimensions of situational meaning. Based on the situational meaning, a value for Temporal Relevance is set. Temporal Relevance reflects the importance of temporal aspects for enabling adaptive behavior in a specific moment in time. When Temporal Relevance is above a certain threshold a prospective duration judgment process is evoked automatically. In addition, a search for relevant temporal information is taking place and its outcomes determine the level of Temporal Uncertainty which reflects the degree of knowledge one has regarding temporal aspects of the task to be performed. The levels of Temporal Relevance and Temporal Uncertainty determine the amount of attentional resources allocated for timing by the executive system. The merit of the model is in connecting timing processes with the ongoing general information processing stream. The model rests on findings in various domains which indicate that cognitive-relevance and self-relevance are powerful determinants of resource allocation policy. The feasibility of the model is demonstrated by analyzing various temporal phenomena. Suggestions for further empirical validation of the model are presented.     

Perceptual fluency effects in judgments of creativity and beauty: creative objects are perceived fluently yet they are visually complex

ABSTRACT

Perceptual fluency typically has a positive influence on aesthetic evaluations of beauty, but few studies have examined its influence on creativity evaluations. Creativity has two facets, originality and quality. If creativity judgments involve estimating product originality, such judgments may be associated with perceptual disfluency, while product quality may be associated with perceptual fluency. We examined the relationship between perceptual fluency and judgments of creativity and beauty across seven experiments. Creativity judgments were affected by most perceptual fluencysources. We observed a highly-fluent-is-beautiful-and-creative relation when testing repeated exposure and figure-ground contrast. Prototypicality displayed a high-fluency–is-beautiful relation, with creativity judgments unaffected. Visual complexity displayed a consistent disfluent-is-creative effect, with mixed results for beauty. For creativity (but not beauty) evaluations, increased saliency of visual complexity led to discounting fluent-is-creative effects, supporting the hypothesis that there are at least two fluency pathways to creativity judgments that take both originality and quality into account.
