The effects of music exposure and own genre preference on conscious and unconscious cognitive processes: a pilot ERP study

Did Beethoven and Mozart have more in common with each other than Clapton and Hendrix? The current research demonstrated the widely reported Mozart Effect as only partly significant. Event-related brain potentials (ERPs) were recorded from 16 professional classical and rock musicians during a standard 2 stimulus visual oddball task, while listening to classical and rock music. During the oddball task participants were required to discriminate between an infrequent target stimulus randomly embedded in a train of repetitive background or standard stimuli. Consistent with previous research, the P3 and N2 ERPs were elicited in response to the infrequent target stimuli. Own genre preference resulted in a reduction in amplitude of the P3 for classical musicians exposed to classical music and rock musicians exposed to rock music. Notably, at the pre-attentive stage of processing (N2) beneficial effects of exposure to classical music were observed for both groups of musicians. These data are discussed in terms of short and long-term music benefits on both conscious and unconscious cognitive processes.     

Mental Health Screening of Female Juvenile Offenders: Replication of a Subtyping Strategy

Recent research indicates that adjudicated female youth have higher rates of mental health problems and histories of trauma exposure and abuse relative to adjudicated male youth. These differences are important for gender-specific assessment, intervention, and management strategies. We replicated a subtyping strategy for adjudicated female youth based on mental health screening data from the Massachusetts Youth Screening Instrument-2 (MAYSI-2) by investigating subtype differences on trauma symptoms, abuse history, and other background variables. Cluster analysis of the standard MAYSI-2 scales revealed a three cluster solution replicating results from a prior study. Additionally, results indicated expected differences between female youth with mental health problems compared to those without mental health problems with co-occurring female youth (i.e., self-reported mental health and substance abuse problems) having have greater mental health problems and more extensive abuse histories compared to other subtypes.     

Examination of the MMPI-2 Restructured Clinical (RC) Scales in a Sample of Bariatric Surgery Candidates

The current study examined the MMPI-2 Restructured Clinical (RC) scales (Tellegen et al., MMPI-2 Restructured Clinical (RC) scales: Development, validation, and interpretation. Minneapolis: University of Minnesota Press, 2003) in a sample of 1,091 bariatric surgery candidates. The RC scales were developed to address concerns about limited discriminant validity of the Clinical scales. Internal consistency and external validity analyses were conducted to evaluate the RC scales in this setting. Results indicated that the RC scales are generally more internally consistent than the Clinical scales and display significantly better convergent and discriminant validity in predicting a variety of behavioral, psychological, and developmental variables relevant to preoperative bariatric psychological evaluations. Implications of the results and recommendations for future research with the RC scales in medical settings are discussed.     

脂多糖受体mCD14定量研究的方法探讨

本文通过横断面研究,时100例正常人群（一次性）采集外周全血2ml,选用流式细胞技术测定单核细胞群、mCD14平均荧光强度值,行盲法测定。观察正常人群外周血mCD14的表达水平,探讨正常人群mCD14定量研究的方法。结果显示单核细胞与淋巴细胞的比值比单个读取mCD14的平均荧光强度值更具可重复性,集中趋势较好,有利于临床应用和比较研究。此方法可作为流式细胞仪定量检测数据校正的方法参考。     

The usability of a Norwegian adaptation of the Children's Communication Checklist Second Edition (CCC-2) in differentiating between language impaired and non-language impaired 6- to 12-year-olds

The aim of the present study was to evaluate if the Norwegian adaptation of the Children's Communication Checklist-2 (CCC-2) differentiates between a language impaired and a non-language impaired population and to make a first evaluation of the psychometric qualities of the questionnaire on a Norwegian sample. A total of 153 children aged 6–12 years participated in the study (45 language impaired and 108 non-language impaired). The Norwegian adaptation of the CCC-2 distinguished language impaired from non-language impaired children and thus seems to provide a useful screening tool for communication impairments in Norwegian children. The reliability of the CCC-2 appeared to be reasonable with internal consistency values ranging from 0.73 to 0.89.     

Using the MMPI-2 to Predict Symptom Reduction During Psychotherapy in a Sample of Community Outpatients

In the present study, potential MMPI-2 predictors of psychotherapy outcome were examined in a community clinical sample of 51 patients seeking treatment at a university training clinic. Results indicated that particular MMPI-2 scales (L, F, Pd, Pa, Sc, Trt) were the most predictive of initial levels of patient distress, whereas three other clinical scales (Hs, D, Hy) were significantly associated with actual symptom reduction over time. The clinical implications of these data include the use of the MMPI-2 in clinical practice as a means to frame the provision of direct feedback to patients regarding the likelihood of treatment response, which in turn, might actually have therapeutic benefits. The limitations of the study are reviewed and suggestions for future research are offered, including the potential use of widely known and utilized instruments in helping to predict response to psychotherapy.     

Acute systemic fibroblast growth factor-2 enhances long-term memory in developing rats

Recent findings have provided much insight into the mechanisms underlying long-term memory formation, and it is now known that long-term memory depends on the activation of a molecular cascade that culminates with structural changes in the brain. However, little is known about the signals that give rise to or regulate these structural changes. In this article we propose that fibroblast growth factor-2 (FGF2), a mitogen for several cell types, may be one of the molecular signals critically involved in the structural changes underlying long-term memory. If FGF2 is part of the signalling cascade involved in long-term memory, then increasing the activation of FGF2 should facilitate memory. In Experiments 1 and 2, we demonstrated that systemic injection of FGF2 (20 ng/g of body weight) facilitated memory for contextual fear in 16, 19, and 22 day old male Sprague Dawley rats. Experiment 3 demonstrated that the observed facilitation of memory was not due to FGF2 increasing rats’ sensitivity to footshock. These results implicate FGF2 as a possible molecular signal in long-term memory, and further, illustrate a novel means of enhancing memory.

<Emphasis Type="Italic">Special Topic:</Emphasis> Confucian and Christian Conceptions of Creativity

In this article the concept of God as creativity (rather than as “the Creator”) is explored. Though creativity is a profound mystery to us humans, it is a plausible concept today because of its interconnectedness with the belief that our cosmos is evolutionary: new orders of reality come into being in the course of time. Three modalities of creativity are explored here: the initial coming into being of the universe (the Big Bang); the creativity manifest in evolutionary processes; the human creation of culture. It is suggested that this creativity itself should be thought of as God: God is creativity. Thus God-talk is given a referent that is specifiable in terms of today’s understandings of the world and the human. God remains a profound mystery here, but one with a significant place in our modern understanding of the world and human life. This article includes text and ideas taken from my book, In the beginning…Creativity (Kaufman 2004).
