Some studies use the term modality to refer to a general difference in performance based upon the mode of presentation. For example, Gibbons demonstrated modality effects in an experiment by making participants count either beeping sounds or visually presented dots. The to-be-remembered number was derived from the number of dots or beeps ...
The worked-example effect is a learning effect predicted by cognitive load theory. [ 1 ] [ full citation needed ] Specifically, it refers to improved learning observed when worked examples are used as part of instruction, compared to other instructional techniques such as problem-solving [ 2 ] [ page needed ] and discovery learning.
The figure on the left side of the image produces the split-attention effect, while the figure on the right enhances learning because it guides the learner's attention through the worked example. Unincorporated visual displays of information, such as the image above, can be distracting and confusing for the user, aside from producing the split ...
In the context of human–computer interaction, a modality is the classification of a single independent channel of input/output between a computer and a human. Such channels may differ based on sensory nature (e.g., visual vs. auditory), [ 1 ] or other significant differences in processing (e.g., text vs. image). [ 2 ]
A list of sign types would include: writing, symbol, index, image, map, graph, diagram, etc. Some combinations of signs can be multi-modal, i.e. different types of signs grouped together for effect. But the distinction between a medium and a modality should be clarified: text is a medium for presenting the modality of natural language;
A modality effect is present in chunking. That is, the mechanism used to convey the list of items to the individual affects how much "chunking" occurs. Experimentally, it has been found that auditory presentation results in a larger amount of grouping in the responses of individuals than visual presentation does. Previous literature, such as George Miller's The Magical Number Seven, Plus or ...
Rosemary Oil. A very common oil included in natural hair growth products, studies have noted the efficacy of rosemary in promoting hair growth. In one study, results showed that rosemary oil may ...
Perceptual learning effects can be organized into two broad categories: discovery effects and fluency effects. [1] Discovery effects involve some change in the bases of response such as in selecting new information relevant for the task, amplifying relevant information or suppressing irrelevant information.
