Sample text

According to some authors (Zarakovsky and Pavlov, 1987), emotions reflect the relationship between our needs and the real or possible success in their satisfaction. , through their link with the goal of activity. , are transformed into motives when they are connected with a goal. A person’s motives can be divided into two groups: sense formative and situational (Leont’ev, 1871). Sense formative motives are relatively stable and determine a person’s general motivational direction. Situational motives are connected with immediate ongoing activity and the performance of a specific task.

At the next stage, these requirements should be compared with the past experience and the motivational state, which leads to the goal acceptance process. A subjectively accepted goal does not always match the objectively presented goal (requirements). Moreover, very often subjects can formulate the goal independently. As it can be seen, a goal always assumes some stage of activity, which requires interpretation and acceptance of the goal. So we can conclude that the goal does not exist in a ready form for the subject and cannot be considered simply as an end state to which human behavior is directed.

This vector defines the direction of activity. This vector is directed at achieving the required goal. , are just new goals, and thus, the new vector that determines the directions of activity is formed and the subject formulates a plan for a new type of activity or task. One goal can contradict another, but this is not an anti-goal, because such goal is created based on the same mechanisms. Consider a hypothetical example. There is a family with children. The father is a gambler. Sometimes after receiving salary, father withdraws all the money from the ATM and spends it in the casino.
