Diagonal plane is defined as a combination of more than one plane. Less than parallel or perpendicular to the sagittal, frontal, or transverse plane. Diagonal plane is also known as Oblique plane.
In psychology, the diagonal plane refers to a theoretical construct that describes a person's level of functioning in terms of their social and occupational roles. Specifically, it represents the intersection between a person's level of competence and their level of motivation or interest in carrying out specific tasks or fulfilling certain roles.
Examples of diagonal plane functioning can be seen in various domains of life, such as work, school, and social relationships. For instance, an individual who has a high level of competence in their job but lacks motivation or interest in their work may have low diagonal plane functioning. Conversely, an individual who has a high level of interest in socializing but lacks social skills may also have low diagonal plane functioning.
One way in which the diagonal plane concept can be applied is in vocational rehabilitation settings, where it is used to assess a person's readiness to return to work following an injury or illness. By assessing an individual's diagonal plane functioning in relation to their occupational role, rehabilitation professionals can determine the most appropriate interventions and supports to help the person return to work successfully.
Similar concepts to the diagonal plane include the "skill-will" matrix and the "competence-motivation" framework. The skill-will matrix is often used in management and leadership contexts to help managers assess their employees' level of competence and motivation and determine the most appropriate management style for each individual. The competence-motivation framework is a broader concept that has been applied in various fields, including education and sports, to understand the factors that influence an individual's level of engagement and success in a particular activity.
Overall, the diagonal plane is a useful construct in psychology that can help us understand how a person's competence and motivation intersect in different domains of life. By identifying areas of low diagonal plane functioning, psychologists and other professionals can develop targeted interventions to help individuals improve their level of functioning and achieve their goals.
