What type of effect in communication leads to new insights and increased knowledge?

The cognitive effect in communication refers to changes in thoughts, understanding, and knowledge that result from the exchange of information. When communication stimulates cognitive processes, individuals are able to analyze, synthesize, and evaluate the information they receive, which leads to new insights and expanded knowledge bases. This effect is particularly important in agricultural extension, where the goal is to educate farmers and empower them with innovative practices and advancements.

In contrast, while emotional effects can influence attitudes and motivation, they do not necessarily lead directly to increased knowledge or understanding. Physical effects might refer to tangible changes in behavior or conditions but lack the substantial cognitive engagement with ideas. Cultural effects may shape how people perceive and prioritize information, yet they do not inherently confer the learning or comprehension that the cognitive effect does.
