Strengths and Weaknesses of the Biological Model and...

Developmental theories embody perspectives about environmental forces and human essence that build a path of human development. Developmental psychopathology theories embody these perspectives as well, and the information from ‘normal’ and ‘pathological’ human life courses enlighten current models of development (Davies Bhugra, 2004). Thus, for instance, the healthy child and the biological model both agree that certain predetermined behavioural pattern may be impervious to environmental forces. Similarly, knowledge about relapse to previous patterns of behaviour necessitates the re-evaluation of the idea that every process of development is a change and; that every previous pattern of behaviour is transformed into entirely new one†¦show more content†¦The biological model distinguishes several of the studies in the genetics of psychological disorder (Joseph, 2006). At this point, environmental factors, or the interface between them and the genes, serve hardly any function in the possible result. For instance, Kallman’s (1946 as cited in Joseph, 2006, 237) study on the genetic aspect of schizophrenia reinforces the application of the biological model, just like the presence or absence of specific substances on depression (ibid, p. 237). In all of these instances, the presence of specific attributes is presumed likely to influence a specific form of pathology. Even though the biological model is remarkable in its straightforwardness, it still has several limitations; for instance, not every individual who has a genetic indicator at a specific point in time is expected to display consequent psychopathology or a similar form of psychopathology (Miller Mason, 2002). For example the case that every child of schizophrenic parents does not develop schizophrenia, or that not every monozygotic twin exhibits similarity in relation to schizophrenia indicates that other factors have to be taken into account. It is vital to emphasise that the failure to come across a significant prevalence of schizophrenic children of schizophrenic parents suggest that factors such as immunity, coping approaches, and invulnerability to stress, are protective factorsShow MoreRelatedOcd - Symptoms, Causes, Treatment131367 Words   |  526 Pagescognitive deficit might account for the persistence of obsessive–compulsive symptoms, and Chapters 5 through 7 discuss current theories and research that are the basis of contemporary CBT for OCD. Chapter 7 presents an expanded cognitive-behavioral model that might provide a more complete account of obsessional phenomena. This new formulation of obsessions emphasizes the importance of faulty secondary appraisals of mental control, as well as the erroneous primary appraisals of the obsession itself
