Age-related changes in auditory and visual perception have an impact on the quality of life. It has been debated how perceptual organization is influenced by advancing age. From the neurochemical perspective, we investigated age effects on auditory and visual bistability. In perceptual bistability, a sequence of sensory inputs induces spontaneous switching between different perceptual objects. ...

Research in perceptual decision making is dominated by paradigms that tap the visual system, such as the random-dot motion (RDM) paradigm. In this study, we investigated whether the behavioral signature of perceptual decisions in the auditory domain is similar to those observed in the visual domain. We developed an auditory version of the RDM task, in which tones correspond to dots and pitch co...

Dissociations between perceptual and imaginal neglect are typically investigated by using very different tasks (e.g. visual target cancellation vs. place descriptions). Here we report patients' performance on imaginal and perceptual tasks which shared identical stimuli and procedure, except for the modality of stimulus presentation. In different tasks, participants either saw towns/regions on a...

Our actions produce physical events that give rise to perceptual information across multiple modalities. A trip to the beach can be identified through all five of our senses: seeing the waves roll in from the horizon, hearing the waves break on the sand, smelling the ocean life, feeling the cool sensation of the water on our skin, and tasting the salty water. Yet information from one perceptual...

In this study, we show that humans form highly similar perceptual spaces when they explore complex objects from a parametrically defined object space in the visual and haptic domains. For this, a three-dimensional parameter space of well-defined, shell-like objects was generated. Participants either explored two-dimensional pictures or three-dimensional, interactive virtual models of these obje...

According to the "embodied cognition" theory and the "sensory-motor model of semantic knowledge": (a) concepts are represented in the brain in the same format in which they are constructed by the sensory-motor system and (b) various conceptual categories differ according to the weight of different kinds of information in their representation. In this study, we tried to check the second assumpti...

This paper presents a review of studies that have provided evidence supporting metaphorical embodiment. These are divided into three categories behavioral, neuroimaging, and corpus studies. After summing up the findings these studies, it is concluded embodiment supported by lines research. followed number measured sensorimotor action effector strengths various concepts. Then, idea strength conc...
