Media-related Influences: In recent times, advancements in audio-visual media and the Internet have emerged as potent sources of information that significantly contribute to attitude formation and change. Additionally, textbooks used in schools also play a role in influencing attitudes. These sources primarily strengthen the cognitive and affective aspects of attitudes and may subsequently impact behavioral components as well. The media and the Internet possess the ability to exert both positive and negative influences on attitudes. On one hand, they enhance people's knowledge and awareness compared to other modes of communication. On the other hand, there is limited control over the quality and nature of the information being disseminated, which can consequently shape attitudes or alter existing ones in unpredictable ways. The media can promote consumerist attitudes where they were absent before, but they can also be harnessed to foster positive attitudes that contribute to social harmony.
