BackgroundProsody, the melody and intonation of speech, involves the rhythm, rate, pitch and voice quality to relay linguistic and emotional information from one individual to another. A significant component of human social communication depends upon interpreting and responding to another person's prosodic tone as well as one's own ability to produce prosodic speech. However there has been little work on whether the perception and production of prosody share common neural processes, and if so, how these might correlate with individual differences in social ability.MethodsThe aim of the present study was to determine the degree to which perception and production of prosody rely on shared neural systems. Using fMRI, neural activity during perception and production of a meaningless phrase in different prosodic intonations was measured. Regions of overlap for production and perception of prosody were found in premotor regions, in particular the left inferior frontal gyrus (IFG). Activity in these regions was further found to correlate with how high an individual scored on two different measures of affective empathy as well as a measure on prosodic production ability.ConclusionsThese data indicate, for the first time, that areas that are important for prosody production may also be utilized for prosody perception, as well as other aspects of social communication and social understanding, such as aspects of empathy and prosodic ability.

This comprehensive analysis addresses the United States' alarming lack of preparedness to respond effectively to a massive disaster as evidenced by Hurricane Katrina. First, a timeline of problematic response events during and after Hurricane Katrina orients readers to some of the specific problems encountered at different levels of government. Second, a list of the "Dirty Dozen"--12 major failures that have occurred in prior disasters, which also contributed to inadequate response during and after Hurricane Katrina--is presented. Third, this article encourages expanding psychology's role beyond the treatment of trauma to encompass disaster planning and mitigation efforts from a broader public health perspective. Finally, areas for important interdisciplinary research in human behavior that will influence our nation's overall preparedness for future catastrophes are identified, and ways psychologists can become personally involved beyond treating casualties are discussed.

BackgroundThe posteromedial cortex (PMC) and medial prefrontal cortex (mPFC) are part of a network of brain regions that has been found to exhibit decreased activity during goal-oriented tasks. This network is thought to support a baseline of brain activity, and is commonly referred to as the “default network”. Although recent reports suggest that the PMC and mPFC are associated with affective, social, and self-referential processes, the relationship between these default network components and personality traits, especially those pertaining to social context, is poorly understood.Methodology/Principal FindingsIn the current investigation, we assessed the relationship between PMC and mPFC deactivations and psychopathic personality traits using fMRI and a self-report measure. We found that PMC deactivations predicted traits related to egocentricity and mPFC deactivations predicted traits related to decision-making.Conclusions/SignificanceThese results suggest that the PMC and mPFC are associated with processes involving self-relevancy and affective decision-making, consistent with previous reports. More generally, these findings suggest a link between default network activity and personality traits.

Systematic Treatment Selection (STS) is a form of technical eclectism that develops and plans treatments using empirically founded principles of psychotherapy. It is a model that provides systematic guidelines for the utilization of different psychotherapeutic strategies based on patient qualities and problem characteristics. Historically, it stems from accumulating evidence that no single theory is effective in treating all patients and common characteristics shared among different theoretical philosophies. A review of the literature and further research resulted in the extraction of four main decisional domains that are involved in determining effective treatment strategies. These domains include: (1) patient predisposing qualities, (2) treatment context, (3) relationship variables, and (4) intervention selection. These main principles provide the basis for which guidelines have been developed to systematically individualize treatment plans. The next step in the process is to effectively disseminate and implement this model, in which students and clinicians are taught to operate from a patient based rather than a theory based perspective.

This study examines point of entry, functional impairment, comorbid diagnosis, and demographic variables as predictors of treatment amount and cost for patients with mental illness and substance abuse disorders in Santa Barbara County Mental Health Services. Overall, significant results were found for point of entry, with higher costs associated with mental health than chemical abuse point of entry. Furthermore, amount, modality, and cost of service varied widely across such variables as functional impairment with those rated as least impaired receiving the greatest amount of services at the greatest cost. Additional significant findings in treatment amount and cost are reported for variables such as homelessness, ethnicity, and age.
