What is mean by top-down and bottom processes give examples for each process?

Bottom-Up vs. Bottom-up processing begins with the retrieval of sensory information from our external environment to build perceptions based on the current input of sensory information. Top-down processing is the interpretation of incoming information based on prior knowledge, experiences, and expectations.

What is top down design explain with example?

In top-down design, a system’s overview is designed, specifying, yet not detailing any first-level subsystems. Then, every subsystem is refined in greater detail, for example, sometimes dividing into many different levels of subsystem, so that the whole specification is decomposed to basic elements.

Is smell top-down or bottom-up?

In bottom-up processing the “stimulation of the preceptors” (p. 50) is done through our senses (sight, touch, smell, hearing, and taste) transferring signals to our brain. On the other hand, top-down processing is “processing that begins with a person’s prior knowledge or expectations” (p52).

Is facial recognition top-down or bottom-up?

Converging evidence from functional neuroimaging and neuropsychological research has revealed that face processing is mediated by a distributed bottom-up cortical network.

Which of the following is an example of bottom to top approach for the preparation of nanomaterials?

2. Which of the following is an example of bottom-up approach for the preparation of nanomaterials? Explanation: Dip pen nanolithography is an example of bottom-down approach for the preparation of nanomaterials.

Which are examples of top-down approach of nanotechnology?

The bottom-up approach involves building of nanomaterials from the atomic scale (assembling materials from atoms/molecules). For synthesis of nanomaterials attrition or ballmilling is a typical example of top-down method and colloidal dispersion is a good example of bottom-up approach.

Is reading an example of bottom-up processing?

Bottom-up processing happens when someone tries to understand language by looking at individual meanings or grammatical characteristics of the most basic units of the text, (e.g. sounds for a listening or words for a reading), and moves from these to trying to understand the whole text.

What are examples of bottom-up approach in nanotechnology?

Some of the methods used in bottom-up approach include plasma arcing, chemical vapor deposition process, metal organic decomposition, laser pyrolysis, molecular beam epitaxy, solgel method, wet synthesis, and self-assembly processes.

What are the examples of top-down approach for the preparation of nanomaterials?

Explanation: Mechanical grinding is an example of top-down approach for the preparation of nanomaterials.

What is top-down processing in listening?

Top-down listening means making as much use as you can of your knowledge and the situation. From your knowledge of situations, contexts, texts, conversations, phrases and sentences, you can understand what you hear.
