Psycho-somatic Disorder Reconsidered

Author(s):  
Donald W. Winnicott

In the final chapter, Winnicott reconsiders psycho-somatic disorder by using two examples: asthma and gastric ulcer. He suggests that asthma studies indicate the condition to be related to environmental factors and to the child’s management of fantasies of love and hate—and possibly to very early birth and breathing difficulties, although Winnicott states that asthma has still not been fully understood. With gastric ulcer, emotional stress and frequent overactivity, as a manic defence against depression, are factors which may bring about the physical condition. Again, unmanageable conflict over love and hate in fantasy may be relevant.

This final chapter explores the future challenges for agroecosystem biology. Factors such as population growth and the requirement for increased agricultural production are considered, alongside environmental factors such as climate change. The chapter explores the potential encroachment of new farmland into natural habitats and the limiting factors for agricultural growth (such as land and water availability). The use of new developments to overcome these limiting factors to agricultural growth is discussed. The chapter concludes with consideration of the potential biological impacts of further expansion and change to global agriculture, and of the implications of agricultural management on biological and other environmental factors.

Environmental factors are recognized as the primary forces dictating the distribution, abundance, and physical condition of pheasants (Phasianus colchicus) and all other game species. These forces, whether beneficial or detrimental, manifest themselves within the physiological mechanisms carrying on the life processes of individuals constituting animal populations. Thus, it might be said that the physiological status of an animal is the expression of all of the environmental factors acting on the animal. This study elucidates changes in selected physiological parameters of wild pheasants in Illinois in relation to stresses that occur during the life cycle of this game bird.

AbstractReductionist thinking in neuroscience is manifest in the widespread use of animal models of neuropsychiatric disorders. Broader investigations of diverse behaviors in non-model organisms and longer-term study of the mechanisms of plasticity will yield fundamental insights into the neurobiological, developmental, genetic, and environmental factors contributing to the “massively multifactorial system networks” which go awry in mental disorders.
