Loudness enhancement and summation in pairs or short sound bursts

When a pair of short, temporally spaced sound bursts is presented and the listeners are requested to match the loudness of a third, comparison burst to the overall loudness of the pair, a fundamentally different result is obtained than when they are instructed to match the loudness of the comparison burst to that of the second burst in the pair. Loudness-level changes occurring in the first situation are designated as loudness summation; those occurring in the second situation, as loudness enhancement. Some parameters of both phenomena are studied. The results lead to the suggestion of a principle of maximum similarity in stimulus matching and to a reinterpretation of some earlier data.     

Walter Bradford Cannon: Reflections on the man and his contributions

My father's early research was with X-rays and led him to a serendipity finding concerning the role of distress in the physiological responses of cats. This chance finding led to further studies of the effects of emotional stimuli on various organs and systems in the body. These studies were the foundation for Cannon's discovery of the fight-or-flight, or stress response, and the development of his companion notion of homeostasis, embodied inThe Wisdom of the Body. While being fond of William James from undergraduate coursework under him, Cannon challenged and refuted the validity of the James-Lange Theory of emotions during his research career. Always fascinated by the psychological and emotional realm of human functioning, Cannon enjoyed warm and close relationships with Robert Yerkes and Ivan Pavlov over the years. The only time in my father's life when he felt strong pressure to produce may have been during World War I when he was part of the Allied medical team solving the problem of traumatic shock experienced by Allied troops in Europe.     

HCV knowledge among a sample of HCV positive Aboriginal Australians residing in New South Wales

Australian Aboriginal and Torres Strait Islanders are overrepresented in both the prevalence and incidence of the hepatitis C (HCV). HCV knowledge has been associated with a range of positive health behaviours. HCV knowledge has previously been investigated as a single construct; however examining different knowledge domains (i.e. transmission, risk of complications, testing and treatment) separately may be beneficial. This study investigated whether having greater HCV knowledge in different domains is associated with self-reported positive health behaviours. 203 Aboriginal people living with HCV completed a survey assessing HCV knowledge, testing and care, lifestyle changes since diagnosis and treatment intent. Respondents’ knowledge was relatively high. Greater knowledge of risk of health complications was associated with undertaking more positive lifestyle changes since diagnosis. Respondents testing and treatment knowledge was significantly associated with incarceration, lifestyle changes since diagnosis and future treatment intentions. This study illustrates the importance of ensuring that knowledge is high across different HCV domains to optimise a range of positive health behaviours of Aboriginal people living with HCV. Future health promotion campaigns targeted at Aboriginal people living with HCV could benefit from broadening their focus from prevention to other domains such as testing and treatment.     

Forgiveness, Gratitude, and Well-Being: The Mediating Role of Affect and Beliefs

Forgiveness and gratitude are positive psychological characteristics that are connected to well-being. This study examined these connections in an understudied population of psychotherapy outpatients and examined the extent to which affect and beliefs mediated these relationships. Participants were 72 outpatients who completed a battery of assessments as part of a standard intake protocol. Results showed that forgiveness and gratitude were both positively and strongly associated with well-being and largely, though not completely, mediated by affect and belief. Forgiveness and gratitude may have an important place in the positive psychologist’s repertoire of well-being enhancing techniques and exercises in general, and may be particularly powerful with a clinical psychotherapy population.     

Relational‐Cultural Theory: A Framework for Bridging Relational,Multicultural, and Social Justice Competencies

Relational‐cultural theory (RCT) theorists advocate expanding the multicultural/social justice counseling competencies beyond the domains of self‐awareness, cultural knowledge, and culturally responsive helping skills. This article provides an overview of RCT and discusses how creating and participating in growth‐fostering relationships are essential dimensions of human development and psychological well‐being. Implications of this theoretical model for counseling practice are also addressed.     

A Self‐Regulatory Model of Resource Scarcity

Academics have shown a growing interest in the effects of resource scarcity—a discrepancy between one's current resource levels and a higher, more desirable reference point. However, the existing literature lacks an overarching theory to explain the breadth of findings across different types of resources. To address this, we introduce a self‐regulatory model of resource scarcity. In it, we propose that consumers respond to resource scarcity through two distinct psychological pathways: a scarcity‐reduction route aimed at reducing the discrepancy in resources and a control‐restoration route aimed at reestablishing diminished personal control by attaining security in other domains. We explain how a key determinant of which route the consumer will pursue is the perceived mutability of the resource discrepancy. We also specify moderators, based on our proposed model, to identify when each of the two routes is pursued. This model is assessed in the context of alternative theoretical perspectives, including commodity theory, life history theory, and models of compensatory behavior. Finally, we provide a research agenda for those interested in studying the psychology of resource scarcity from a self‐regulatory perspective.     

Changes in affect during treatment for depression and anxiety

We tested the hypothesis that the tripartite model [Clark, L. A., & Watson, D. (1991). Tripartite model of anxiety and depression: Psychometric evidence and psychometric implications. Journal of Abnormal Psychology, 100, 316-336] can be extended to account for change during treatment for anxiety and depression. Forty-one patients treated naturalistically in private practice with cognitive behavior therapy completed weekly measures of depression, anxiety, negative affect (NA), positive affect (PA), and anxious arousal (AA). Consistent with the model, NA was associated with anxiety and depression during treatment, PA was more strongly related to depression than to anxiety, and AA was more strongly related to anxiety than to depression. As predicted, symptoms of depression and anxiety and NA all decreased during treatment. As predicted, AA also decreased, particularly for patients with panic disorder. PA increased during treatment, but only for patients who showed a significant decline in depression and only over an extended period of treatment. Nearly two-thirds of the variance in anxiety change was accounted for by changes in depression and NA, and just over three-fourths of the variance in depression change was accounted for by changes in anxiety and NA, indicating that much of the change in anxiety and depression across the course of treatment is shared in common.
