Object Recognition in Mental Representations: Directions for Exploring Diagnostic Features through Visual Mental Imagery
One of the fundamental goals of object recognition research is to understand how a cognitive representation produced from the output of filtered and transformed sensory information facilitates efficient viewer behavior. Given that mental imagery strongly resembles perceptual processes in both cortical regions and subjective visual qualities, it is reasonable to question whether mental imagery f...
متن کاملDiagnostic Object Motion Weakens Representations of Static Form
Past studies have shown that information about how objects move can play an important role in their recognition. Flow-fields associated with an object’s intrinsic motion, and also the sequence of views it presents over time can be used to identify the object and also link its disparate appearances. In the current study, we demonstrate that diagnostic object motion is such a perceptually signifi...
متن کاملFlexible Representations of Dynamics Are Used in Object Manipulation
To manipulate an object skillfully, the brain must learn its dynamics, specifying the mapping between applied force and motion. A fundamental issue in sensorimotor control is whether such dynamics are represented in an extrinsic frame of reference tied to the object or an intrinsic frame of reference linked to the arm. Although previous studies have suggested that objects are represented in arm...
متن کاملAre Verbs Less Prominent?
The perceived prominence of three parts of speech (POS), nouns, verbs and adjectives, in three utterance positions, initial, intermediate and final, were examined in a perceptual experiment to see whether previously observed reductions in prominence of intermediate items were the result of positional effects or because words in this position belonged to the same POS, namely verbs. It was found ...
متن کاملHigh-level visual object representations are constrained by position.
It is widely assumed that high-level visual object representations are position-independent (or invariant). While there is sensitivity to position in high-level object-selective cortex, position and object identity are thought to be encoded independently in the population response such that position information is available across objects and object information is available across positions. Co...
