Freud, Psychoanalysis and Symbolism offers an innovative general theory of symbolism, derived from Freud's psychoanalytic theory and relocated within mainstream scientific psychology. It is the first systematic investigation of the development of Freud's treatment of symbolism throughout his published works, and discovers in those writings a broad theory which is far superior to the widely accepted, narrow, 'official' view. Agnes Petocz argues that the treatment of symbolism must begin with the identification and clarification of a set of logical constraints and psychological requirements which any general theory of symbolism must respect, and that these requirements have been neglected by existing accounts across a number of disciplines. Her newly proposed 'Freudian broad' theory of symbolism, by contrast, does meet these requirements, but only after it has been rehabilitated within a revised psychoanalytic context, encompassing major changes to our understanding of the concepts of unconscious and repression and the role of language.

In auditory warning design the idea of the strength of the association between sound and referent has been pivotal. Research has proceeded via constructing classification systems of signal-referent associations and then testing predictions about ease of learning of different levels of signal-referent relation strength across and within different types of auditory signal (viz., speech, abstract sounds, and auditory icons). However, progress is hampered by terminological confusions and by neglect of the cognitive contribution (viz., learning) of the person or user. Drawing upon semiotics and cognitive psychology, the authors highlight the indexical (as opposed to iconic) nature of so-called auditory icons, and the authors identify the cogniser as an indispensable element in the tripartite nature of signification. Classifications that neglect this third element, defining signal-referent relation strength only dyadically, yield results confounded by learning; classifications that correctly include the triadic relation yield research predictions that are redundant. These limitations of the standard method of constructing and testing classification systems suggest that auditory warning design must take the cognitive contribution of the user into account at an earlier stage in the design process.

An experiment investigated the assumption that natural indicators which exploit existing learned associations between a signal and an event make more effective warnings than previously unlearned symbolic indicators. Signal modality (visual, auditory) and task demand (low, high) were also manipulated. Warning effectiveness was indexed by accuracy and reaction time (RT) recorded during training and dual task test phases. Thirty-six participants were trained to recognize 4 natural and 4 symbolic indicators, either visual or auditory, paired with critical incidents from an aviation context. As hypothesized, accuracy was greater and RT was faster in response to natural indicators during the training phase. This pattern of responding was upheld in test phase conditions with respect to accuracy but observed in RT only in test phase conditions involving high demand and the auditory modality. Using the experiment as a specific example, we argue for the importance of considering the cognitive contribution of the user (viz., prior learned associations) in the warning design process. Drawing on semiotics and cognitive psychology, we highlight the indexical nature of so-called auditory icons or natural indicators and argue that the cogniser is an indispensable element in the tripartite nature of signification.

We propose that a coherent and thoroughgoing version of realism, known as situational realism, offers a unifying program for psychology. This realism emerges from the conditions of being that enable knowledge and discourse. Because this research originated largely in a century's work by Australian psychologists and philosophers, we will introduce and explain research and vocabulary that might be unfamiliar to some readers. The approach is characterized by seven themes: ontological egalitarianism; situational complexity and process orientation; a network or field view of causality; a realist logic; a view of relations as nonconstitutive; an externalist relational approach to mind; and acceptance of critical inquiry as the core scientific method. The combination of these features offers psychology the following: a metatheoretical framework that resolves current tensions; expansion into the field of meanings and reintegration with hermeneutics and semiotics; clarification and redirection of mainstream cognitive neuroscience and information processing; an integrative approach to personality; expansion, redirection and unification of psychological research methods; and revision and expansion in psychological practice and teaching.

Psychology is flourishing. It is a hugely popular subject for study. In application it finds its way into all corners of modern life. In empirical research there seems hardly a topic that the many thousands of research psychologists in departments around the world do not investigate. And the development of varied and sophisticated techniques, from statistical modelling and multivariate analyses, to computer-aided content analysis, to nuclear magnetic resonance imaging, is extending its reach into areas inaccessible just a few decades ago. The sheer volume of research output is enormous, with some 200,000 references added annually to the American Psychological Association's data base.
