Cerebral blood flow differences between long-term meditators and non-meditators

We have studied a number of long-term meditators in previous studies. The purpose of this study was to determine if there are differences in baseline brain function of experienced meditators compared to non-meditators. All subjects were recruited as part of an ongoing study of different meditation practices. We evaluated 12 advanced meditators and 14 non-meditators with cerebral blood flow (CBF) SPECT imaging at rest. Images were analyzed with both region of interest and statistical parametric mapping. The CBF of long-term meditators was significantly higher (p < .05) compared to non-meditators in the prefrontal cortex, parietal cortex, thalamus, putamen, caudate, and midbrain. There was also a significant difference in the thalamic laterality with long-term meditators having greater asymmetry. The observed changes associated with long-term meditation appear in structures that underlie the attention network and also those that relate to emotion and autonomic function.     

Mindfulness-Based Childbirth and Parenting Education: Promoting Family Mindfulness During the Perinatal Period

We present the conceptual and empirical foundation and curriculum content of the Mindfulness-Based Childbirth and Parenting (MBCP) program and the results of a pilot study of n = 27 pregnant women participating in MBCP during their third trimester of pregnancy. MBCP is a formal adaptation of the Mindfulness-Based Stress Reduction program and was developed and refined over the course of 11 years of clinical practice with 59 groups of expectant couples. MBCP is designed to promote family health and well-being through the practice of mindfulness during pregnancy, childbirth, and early parenting. Quantitative results from the current study include statistically significant increases in mindfulness and positive affect, and decreases in pregnancy anxiety, depression, and negative affect from pre- to post-test (p < .05). Effect sizes for changes in key hypothesized intervention mediators were large (d > .70), suggesting that MBCP is achieving its intended effects on maternal well-being during pregnancy. Qualitative reports from participants expand upon the quantitative findings, with the majority of participants reporting perceived benefits of using mindfulness practices during the perinatal period and early parenting. Our future research will involve conducting a randomized controlled trial of MBCP to test effects on psychophysiological stress mechanisms and to examine effects on birth outcomes, family relationship quality, and child development outcomes.     

Current Treatment Practices for Children and Adults With Trichotillomania: Consensus Among Experts

Very little is known regarding the efficacy of pharmacological and psychosocial treatments for children and adults with trichotillomania (TTM). Given this dearth of information, the present investigation sought to examine the treatment practices of members of the nationally recognized Trichotillomania Learning Center–Scientific Advisory Board (TLC-SAB) and practitioners known by members of the TLC-SAB to possess extensive experience working with this population. The responses of 67 practitioners to an Internet-based survey were examined. Our results clearly indicate that cognitive-behavioral treatment (CBT) is the treatment of choice for both children and adults with TTM. In particular, several components of CBT (i.e., awareness training, self-monitoring, competing response training, habit reversal training, and stimulus control) are implemented most often. Selective serotonin reuptake inhibitors (SSRIs, e.g., citalopram, fluoxetine) and serotonin-norepinepherine reuptake inhibitors (SNRIs, e.g., venlafaxine, duloxetine) were prescribed most frequently; however, these results are preliminary given our small sample of prescribing practitioners (n = 11). Taken together, these findings are a critical starting point to advancing the understanding of efficacious interventions for the treatment of individuals with TTM. Clinical and research implications, future areas of research, and study limitations are discussed.     

The malleable bicultural consumer: effects of cultural contexts on aesthetic judgments

• Grounded in the cognitive framework of processing fluency, this study proposes further support for the experiential perspective in aesthetics by positing that aesthetic response to the same object may be malleable, depending on how the symbolic properties of the object interact with different cultural contexts which either facilitate or debilitate the processing experience of the perceiver. The study employed an Internet experiment to test the hypotheses among 105 female Hispanic college‐aged students enrolled at a large midwestern university. The findings revealed that symbolic attributes of products interact with cultural contexts to affect aesthetic judgments of (Hispanic) consumers. Aesthetic judgments were more positive when evaluating culturally symbolic product attributes after exposure to congruent contextual cues that facilitate fluent processing. The study furnishes support for the impact of environment/context on consumer behavior and aesthetic judgment, thus establishing further support for the cognitive framework of conceptual fluency in explaining aesthetic response. The study also contributes to recent literature on “frame‐switching” among bicultural consumers by suggesting that these consumers navigate between competing cultural frames in response to visual primes, with resultant shifts in aesthetic judgments. Important marketing insights emerge from these findings.

Cultural Missteps and Ethical Considerations with Indigenous Populations: Preliminary Reflections from Northeastern Ontario,Canada

Within this submission the authors share their experiences as a blended research team with Aboriginal community and mainstream academic researchers. The team has collaborated since 2004 on several externally funded research projects. Initially, the team engaged in research through mainstream methodologies. In the process, the community co-researchers and participants were silenced through mainstream cultural practices that were unfamiliar and meaningless in Wikwemikong culture. More recently, the team has employed a community conceived de-colonizing methodology, developed from within Wikwemikong Unceded Indian Reserve. Within this submission, the authors will highlight their initial cultural missteps, followed by more recently utilized culturally relevant approaches. It is proposed that what might be ethically sound research with mainstream participants and among mainstream researchers can silence and subvert practices among those from marginalized groups/cultures. Provisional suggestions are offered for researchers interested in co-researching in Aboriginal communities.     

A Motivational Model of Daily Hassles,Physical Symptoms,and Future Work Intentions Among Police Officers1

This study tested a motivational model of daily hassles, physical symptoms, and future work intentions with a sample of 122 police officers. In agreement with self‐determination theory (Deci & Ryan, 1985, 2002), path analyses showed that police officers who perceived their immediate supervisor as highly supportive of their autonomy were found to report higher levels of self‐determined motivation toward work. In turn, higher levels of self‐determined motivation were found to be associated with higher future work intentions and lower levels of reported daily hassles. Finally, daily hassles were found to be positively associated with reported physical symptoms. Contrary to our hypotheses, perception of competence support from supervisors was not found to be significantly associated with self‐determined motivation. Instead, competence support was found to be negatively associated with daily hassles.
