The primacy and recency effect refers to the phenomenon where people tend to remember the first and last items in a series or sequence more easily and vividly compared to the middle items. This effect has been widely studied in various fields, including psychology, marketing, and communication.

When it comes to forming impressions, the first and last interactions play a crucial role in shaping our overall perception. Let's take a look at why these impressions matter:

The Primacy Effect:

The primacy effect suggests that the first information we encounter has a disproportionately large impact on our overall impression. This is because our initial encounter sets the tone and framework for how we perceive subsequent information. For example, when meeting someone for the first time, our initial impression can influence how we interpret their subsequent actions and behaviors.

Research has shown that the primacy effect can influence decision-making processes. In a study by Asch (1946), participants were presented with a list of positive and negative traits about a person. Those who read the positive traits first rated the person more favorably compared to those who read the negative traits first.

The Recency Effect:

The recency effect, on the other hand, suggests that the last information we encounter also has a significant impact on our impression. This is because the most recent information is still fresh in our memory and can have a stronger influence on our overall judgment. For example, in a job interview, the final moments of the interview can leave a lasting impression on the interviewer.

Studies have shown that the recency effect can be particularly strong when there is a delay between the presentation of information and the judgment. In a study by Glanzer and Cunitz (1966), participants were presented with a list of words and then asked to recall them. Participants were more likely to remember the words at the end of the list compared to those in the middle.

Implications and Applications:

The primacy and recency effects have important implications in various areas:

• In marketing and advertising, companies often strategically place their most important information at the beginning and end of commercials or presentations to maximize the impact on consumers.
• In public speaking, speakers often strive to make a strong opening and closing statement to captivate and leave a lasting impression on the audience.
• In job interviews, candidates can make use of the recency effect by ensuring a strong finish and leaving a positive final impression on the interviewer.

It is important to note that while the primacy and recency effects can be powerful, they are not the sole factors influencing our impressions. Other factors such as overall quality, relevance, and personal biases also play a role. Nevertheless, understanding and harnessing the power of these effects can help us make more impactful and memorable impressions.
