Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| The dorsal and ventral visual pathways are separate and independent systems. | While the dorsal and ventral pathways have distinct functions, they work together to process visual information. They are interconnected and communicate with each other throughout the processing of visual stimuli. |
| The dorsal pathway is solely responsible for spatial perception and action planning, while the ventral pathway is solely responsible for object recognition. | While it’s true that the dorsal pathway plays a significant role in spatial perception and action planning, it also contributes to object recognition by providing information about an object’s location in space relative to our body or other objects in our environment. Similarly, while the ventral pathway is primarily involved in object recognition, it also provides some spatial information about an object’s size, shape, orientation etc., which can be useful for guiding actions towards that object. |
| The dorsal pathway only processes motion information while the ventral pathway only processes color information. | Both pathways process a wide range of visual features including but not limited to motion (dorsal) and color (ventral). For example, both pathways contribute to processing texture gradients which help us perceive depth cues such as surface roughness or smoothness of objects in our environment. |
| Damage to either one of these pathways results in complete loss of function associated with that particular stream. | In reality damage may result in selective impairments rather than complete loss of function associated with one stream over another depending on factors like severity/location/type/extent/timing etc.,of injury/damage sustained by different parts within each stream as well as individual differences between people regarding their neural organization/functioning patterns. |
