Information processing theory is a psychological model that explains how individuals perceive, process, and retrieve information from their environment. This theory has significant implications for media students as it can help them understand how people interact with media, the factors that influence their media use, and how media can influence their attitudes and behavior. In this essay, we will discuss the main components of the information processing theory, its relevance to media students, and the empirical evidence that supports this theory.
The Information Processing Theory The information processing theory posits that human cognition operates much like a computer, with information passing through a series of cognitive processes. These processes include attention, perception, encoding, storage, and retrieval. Attention refers to the ability to focus on specific stimuli, while perception involves interpreting these stimuli based on past experiences and knowledge. Encoding involves transforming information into a form that can be stored in memory, while storage refers to the retention of information over time. Retrieval involves accessing stored information when it is needed (Sternberg, 2006).
Relevance to Media Students Media students can benefit from understanding the information processing theory in several ways. First, it can help them understand how people process information from media. For instance, when people are exposed to media, they select certain information to attend to and interpret it based on their prior knowledge and experiences. This can help explain why people may have different interpretations of the same media content, depending on their background and beliefs.
Second, the information processing theory can help media students understand how media can influence attitudes and behavior. According to the theory, media can affect the encoding and retrieval of information by altering the accessibility of certain information in memory. This means that exposure to media can influence the types of information that people remember and use to make judgments and decisions. For instance, research has shown that exposure to violent media can increase aggression in some individuals (Anderson et al., 2003). Understanding the mechanisms underlying these effects can help media students develop strategies for creating and evaluating media content that is less likely to have negative effects.
Empirical Evidence Empirical evidence supports the information processing theory. For instance, research has shown that attentional processes are critical for encoding information in memory (Baddeley, 2012). Studies have also shown that individuals who are better at selective attention tend to have better memory (Unsworth & Spillers, 2010).
Moreover, the theory has been applied to the study of media effects. For instance, research has shown that exposure to media can influence the accessibility of information in memory. For example, exposure to violent media can increase the accessibility of aggressive thoughts and feelings, which in turn can increase the likelihood of aggressive behavior (Anderson et al., 2003). Exposure to positive media, on the other hand, can increase the accessibility of positive thoughts and feelings, which may improve well-being (Ritterfeld et al., 2004).
Conclusion In conclusion, the information processing theory can be a useful framework for understanding how people interact with media. It posits that attention, perception, encoding, storage, and retrieval are critical cognitive processes that enable individuals to process and use information from media. For media students, understanding this theory can help them create and evaluate media content that is less likely to have negative effects on attitudes and behavior. Empirical evidence supports the information processing theory, highlighting its relevance for both research and practice in the media field.
