The diagnosis of non-organic failure to thrive syndrome typically requires the assessment of the infant’s growth and development patterns. In this context, the correct answer highlights that the infant demonstrates a delay in psychomotor development, which can be a crucial indicator of non-organic failure to thrive.

Non-organic failure to thrive is often characterized by inadequate growth not directly linked to identifiable medical conditions or organic causes. Psychomotor developmental delays can signify that the underlying issues affecting the child's growth are not solely nutritional but also may be related to environmental and emotional factors, such as caregiver attachment or social context.

In contrast, other options do not align with the necessary diagnostic criteria for non-organic failure to thrive. For example, being above the normal height range does not indicate failure to thrive and might suggest appropriate growth in other contexts. An increased appetite typically contradicts the idea of failure to thrive, as it often indicates that the infant is getting enough nutrition. Lastly, regular weight gain is usually an indicator of healthy growth and would not support a diagnosis of failure to thrive. Thus, the presence of developmental delay is particularly significant when considering non-organic factors impacting the infant's health and growth trajectory.
