Why are animal signals reliable? This is the central problem for evolutionary biologists interested in signals. Of course, not all signals are reliable; but most are, otherwise receivers of signals would ignore them. A number of theoretical answers have been proposed and empirical studies made, but there still remains a considerable amount of confusion. The authors, one a theoretician the other a fieldworker, introduce a sense of order to this chaos. A significant cause of confusion has been the tendency for different researchers to use either the same term with different meanings, or different terms with the same meaning. The authors attempt to clarify these differences. A second cause of confusion has arisen because many biologists continue to assume that there is only one correct explanation for signal reliability. The authors argue that the reliability of signals is maintained in several ways, relevant in different circumstances, and that biologists must learn to distinguish between them. In this book they explain the different theories, give examples of signalling systems to which one or another theory applies, and point to the many areas where further work, both theoretical and empirical, is required.

Psychology, Mental Health and Distress

Is depression simply the result of chemical imbalances, or Schizophrenia a wholly biological disorder? What role do the broader circumstances of an individual’s social, cultural and heuristic world play in the wider scheme of their psychological wellbeing? In this ground-breaking and highly innovative text, Cromby et al deliver an introduction to the the biopsychosocial paradigm for understanding and treating psychological distress, taking into consideration the wider contexts that engender the onset of mental illness and critiquing the limitations in the sole use of the biomedical model in psychological practice. Rather than biologically determined or clinically measurable, readers are encouraged to consider mental illness as a subjective experience that is expressed according to the individual experiences of the sufferer rather than the rigidity of diagnostic categories. Similarly, approaches to recovery expand beyond psychiatric medication to consider the fundamental function of methods such as psychotherapy, community psychology and service-user movements in the recovery process. Offering a holistic account of the experience of psychological distress, this text draws upon not only statistical evidence but places an integral emphasis on the service-user experience; anecdotal accounts of which feature throughout in order to provide readers with the perspective of the mental health sufferer. Taking an integrative approach to the psychology of mental health, the authors draw from a wealth of experience, examples and approaches to present this student-friendly and engaging text. This is core reading for anyone serious about understanding mental health issues and is suitable for undergraduate students taking introductory courses in psychology and abnormal psychology.
