Reconsidering the Evolution of Nonlinguistic Communication: The Case of Laughter

Nonlinguistic communication is typically proposed to convey representational messages, implying that particular signals are associated with specific signaler emotions, intentions, or external referents. However, common signals produced by both nonhuman primates and humans may not exhibit such specificity, with human laughter for example showing significant diversity in both acoustic form and production context. We therefore outline an alternative to the representational approach, arguing that laughter and other nonlinguistic vocalizations are used to influence the affective states of listeners, thereby also affecting their behavior. In the case of laughter, we propose a primary function of accentuating or inducing positive affect in the perceiver in order to promote a more favorable stance toward the laugher. Two simple strategies are identified, namely producing laughter with acoustic features that have an immediate impact on listener arousal, and pairing these sounds with positive affect in the listener to create learned affective responses. Both depend on factors like the listener's current emotional state and past interactions with the vocalizer, with laughers predicted to adjust their sounds accordingly. This approach is used to explain findings from two experimental studies that examined the use of laughter in same-sex and different-sex dyads composed of either friends or strangers, and may be applicable to other forms of nonlinguistic communication.     

Rhetoric to action: a study of stakeholder perceptions of aging well in two local communities

This qualitative study of local perceptions of policy goals and action in relation to aging reports 31 stakeholder interviews within 2 Australian communities exploring (a) the meaning of aging well; and (b) preferred policy actions to achieve positive aging outcomes. Findings suggest that community perceptions of aging well are broadly consistent with the goals of national and international policy frameworks in focusing on 3 dimensions--health, social engagement, and security. Further, participants believe that achievement of positive aging outcomes requires a mix of self-help, community action, and government intervention--particularly government support and encouragement for aging well initiatives.     

Best Practices in Online Therapy

ABSTRACT

This article discusses important issues in delivery of best practice Internet-based therapy (etherapy). Etherapy is first defined as the interaction between a consumer and a therapist via the Internet (commonly via e-mail) in association with the use of a structured web-based clinical treatment program. A summary of the professional and ethical issues is provided, along with illustrated examples of best-practice principles experienced in clinical and research work by members of the Swinburne University of Technology Etherapy Unit (formerly the Etherapy Research, Education, and Training Unit in the Department of General Practice at Monash University). Etherapy has been found to be effective in treating a range of psychological disorders. Future research investigating methods of enhancing consumers' ability to engage in etherapy should further increase the effectiveness of this type of therapy.     

Career Research From an Action Perspective: The Self-Confrontation Procedure

A videotape playback procedure (self-confrontation) following a career-related conversation is proposed as a means of studying career development from an action perspective. This perspective is premised on an understanding of career development as intentional, goal-directed, and occurring in a social context. In this article, a career conversation between a parent and an adolescent is used to illustrate the procedure. During the individual playback, the participants are asked for their thoughts and feelings (cognitions) while the conversation took place, and their interpretation of it. The categories used in the analysis are described. This procedure provides contextually-sensitive and empirically-grounded data useful for researchers and practitioners.

Do we measure leadership effectively? Articulating and evaluating scale development psychometrics for best practice

Leadership assessment has been a particular point of difficulty for contemporary scholarship, with many practitioners rejecting academically-driven leadership instruments and scales and preferring their own, less rigorous, scales. We believe that current conceptualizations and measurements of leadership are problematic, indicated by contemporary challenges that can be widely understood as failures of leadership (e.g. the Australian Banking Royal Commission and Volkswagen's ‘Dieselgate’). Also, how effective leadership is measured needs to change. This paper presents a systematic review of 17 leadership scales developed in the new millennium. The majority of scales lack some degree of rigor. Our response has been to conduct eighteen critical checks over four stages of scale development: theory generation, item development, content validity, and empirical evaluation. On the premise that understanding past practices, with their limitations, can be used to drive forward a suite of more effective organizational tools, we provide best practice recommendations using contemporary psychometric research.     

Diversity and inclusion in local governance: An Australian study of seniors' participation

The importance of hearing older people's voices within local governance processes is well recognised; however, the increasing diversity among older people makes this complex. Questions around inclusion and exclusion, representation and representativeness create challenges for the ways in which diverse older people are engaged. This paper uses the results from a qualitative study conducted in Australia to address the key research question: how does diversity impact on older people's perceptions and experiences of barriers to participation in local governance? Results indicate that diversity impacts not simply on what barriers are reported by seniors, but on how those barriers are experienced. Patterns among the barriers reported and their relationship with diversity reflect questions around representation and inclusion. Thus despite broad acceptance of the notion that understanding diversity is integral to inclusion, challenges remain for older people's engagement with local governance processes. A deeper understanding of diversity and how it relates to inclusion are required.     

Role of Clinical Diagnosis and Medication Use in Effects of Maternal Depression on Infant‐Directed Speech

Infant‐directed (ID) speech was recorded from mothers as they interacted with their 4‐ to 12‐month‐old infants. Hierarchical regression analyses revealed that two variables, age of the mother and mother's diagnosed depression, independently accounted for significant proportions of the variance in the extent of change in fundamental frequency (ΔF0). Specifically, depressed mothers produced ID speech with smaller ΔF0 than did nondepressed mothers, and older mothers produced ID speech with larger ΔF0 than did younger mothers. Mothers who were taking antidepressant medication and who were diagnosed as being in at least partial remission produced ID speech with mean ΔF0 values that were comparable to those of nondepressed mothers. These results demonstrate explicit associations between major depressive disorder and an acoustic attribute of ID speech that is highly salient to young infants.
