Extended music cognition

Discussions of extended cognition have increasingly engaged with the empirical and methodological practices of cognitive science and psychology. One topic that has received increased attention from those interested in the extended mind is music cognition. A number of authors have argued that music not only shapes emotional and cognitive processes, but also that it extends those processes beyond the bodily envelope. The aim of this paper is to evaluate the case for extended music cognition. Two accounts are examined in detail: Joel Krueger’s “musically extended emotional mind” and Tom Cochrane’s “expression and extended cognition.” Each account is evaluated using three “anti-extension” arguments. I argue that Krueger and Cochrane’s accounts offer important steps toward extended music cognition, but that each account remains underdeveloped in various ways. To supplement existing approaches, I propose a complementary extended computational approach to music cognition (ECMC). The claim is that music cognition forms part of an extended system in virtue of involving computational processes that range across environmental and in-the-head elements. The paper concludes by showing how the ECMC deals with each of the three anti-extension challenges and responds to objections.     

An Examination of Biodata Theory‐Based Constructs in a Field Context

This study examined whether items from a biodata inventory were consistent with theory‐based constructs as suggested by the ecology model. The model posits five constructs explain biodata predictive ability. Items were sorted using the theory‐based construct domains. The resulting scale scores were assessed for evidence of content, criterion‐related, and construct validity in a sample of 6032 automated systems controllers. Results suggested moderate support for the theory‐based constructs. A notable finding was that items capturing a theoretical construct were impacted by the life stage in which they were anchored. Results further suggest the need to examine if certain life stages are more predictive than others or perhaps if certain constructs are more predictive when related to a particular life stage.     

Neurosteroids for a successful pregnancy

Steroid hormones play a critical role in the initiation and maintenance of pregnancy. In particular, the important role that the progesterone metabolite, and neurosteroid, allopregnanolone, may play in fetal and adolescent development is becoming increasingly evident. Unlike steroid hormones, neurosteroids act at nontraditional targets in the central and peripheral nervous systems, including GABA(A) receptor complexes. This commentary discusses the three works in this issue that elucidate the important role of allopregnanolone in the mechanisms that regulate stress hypo-sensitivity of rodents in late pregnancy, neuroprotective effects in fetal sheep exposed to a hypoxic insult, and the continuing role that prefrontal cortex formation of allopregnanolone may play on the cognitive development of gestationally stressed rat offspring, grown to adolescence. The narrative that these works comprise was facilitated by the 5(th) International Meeting on Steroids and the Nervous System (Torino, Italy), which is organized to update our knowledge on the relationships between steroid hormones synthesized in different organs and the nervous system. Topics covered in this most recent meeting included sex differences in, and hormonal influences on, cannabinoid-regulated biology; steroids and pain; the importance of co-regulatory factors for steroid receptor action in the brain; mechanism and role of estrogen-induced nonclassical signaling in the brain; vitamin D as the forgotten neurosteroid; neurosteroids and GABA(A) receptors; and pathogenic mechanisms mediated by glucocorticoid receptors in psychiatric disorders. The 6(th) International Meeting on Steroids and the Nervous System will be held in Torino, Italy in February 2011.     

Religiosity and treatment response to antidepressant medication: A prospective multi-site clinical trial

The present study examined the relationship between religiosity/spirituality and treatment response to antidepressant medication (citalopram). One-hundred and forty-eight Caucasian and African-American adults with uncomplicated major depression were treated with citalopram (20-60mg/day) over an 8-week period in a prospective multi-site clinical trial. Treatment response was assessed weekly with the Hamilton Rating Scale for Depression. Religiosity (i.e., religious behaviours) and spirituality (i.e., spiritual well-being) were assessed at Week 3. No significant associations between spirituality and treatment response were found; however, there was a strong curvilinear relationship between religiosity and treatment response. Compared to lower or higher levels of religiosity, a moderate level of religiosity was significantly associated with a higher likelihood of remission and greater reduction in severity of depression. This association was independent of social support, ethnicity, gender, education, and baseline depression severity. A moderate amount of religiosity appears to be independently associated with an enhanced treatment response to citalopram.     

Innovative Ideas on How Work-Family Research Can Have More Impact

The commentaries on our focal article agreed with its main premise that work-family research should follow new strategies to improve its practical impact, and made suggestions clustering into three main themes. The first theme built on our suggestion to improve the research focus, terminology, and framing of work-family research. These essays offered additional ideas such as decoupling work-family from work-life research, and examining contextual factors more deeply. The second theme focused on how to better apply the findings from work family research. These commentaries provided social change approaches for making work-family issues more central to key stakeholders and to organizations. The third theme focused on broadening our scope to the societal level. These editorials advocated tactics supporting the development of basic rights of work-life balance within and across nations.     

Does human capital matter? A meta-analysis of the relationship between human capital and firm performance

Theory at both the micro and macro level predicts that investments in superior human capital generate better firm-level performance. However, human capital takes time and money to develop or acquire, which potentially offsets its positive benefits. Indeed, extant tests appear equivocal regarding its impact. To clarify what is known, we meta-analyzed effects drawn from 66 studies of the human capital-firm performance relationship and investigated 3 moderators suggested by resource-based theory. We found that human capital relates strongly to performance, especially when the human capital in question is not readily tradable in labor markets and when researchers use operational performance measures that are not subject to profit appropriation. Our results suggest that managers should invest in programs that increase and retain firm-specific human capital.     

Strategies and attributes of highly productive scholars and contributors to the school psychology literature: recommendations for increasing scholarly productivity

In all academic fields, there are scholars who contribute to the research literature at exceptionally high levels. The goal of the current study was to discover what school psychology researchers with remarkably high levels of journal publication do to be so productive. In Study 1, 94 highly productive school psychology scholars were identified from past research, and 51 (39 men, 12 women) submitted individual, short-answer responses to a 5-item questionnaire regarding their research strategies. A constant comparative approach was employed to sort and code individual sentiments (N=479) into categories. Seven broad categories of counsel for increasing productivity emerged: (a) research and publication practices and strategies, (b) collaboration, mentoring and building relationships, (c) navigating the peer-review process, (d) strategies to bolster writing productivity and excellence, (e) personal character traits that foster productivity, (f) preparation before entering the professoriate, and (g) other noteworthy sentiments. Results are discussed in terms of nine recommendations for scholars and graduate students who wish to increase their productivity. In Study 2, five of the most productive scholars (1 woman, 4 men) participated in a semi-structured interview about their high levels of productivity. Interviews were recorded, transcribed, and analyzed, and a case analysis approach employed to profile each scholar. Study limitations and suggestions for future research are discussed.     

Use of ratings of perceived exertion to anticipate treadmill test termination in patients taking beta-blockers

This investigation identified a perceptually-based "warning zone" that can be used to anticipate termination of treadmill tests administered to individuals taking beta-blockers. The use of ratings of perceived exertion to anticipate test termination may be valuable given the attenuation of heart rate associated with the use of this class of medication. Sixteen men with coronary artery disease participated in this investigation. Ratings of perceived exertion (Borg 6-20 Scale) were estimated during the last 15 sec. of each minute of a progressively incremented treadmill test. Tests were terminated when participants indicated they were too fatigued to continue. The time-to-test termination was determined from the point that participants estimated a rating of 10, 11, 12, 13, 14, 15, 16, and 17 in order to determine the rating that was less than or equal to the time associated with a single exercise stage. A rating of 14 was associated with impending termination, which can be used as a "warning zone." The time to termination corresponding to a rating of 14 was 153.1 sec. (SD = 27.0). Participants exercised for 153.1 sec. (SE = 27.0) after estimating a rating of 14. Once a rating of 14 is reached, volitional test termination will occur before the next exercise stage is completed.     

Phenomenology and Theology: Situating Heidegger’s Philosophy of Religion

This essay considers the philosophical and theological significance of the phenomenological analysis of Christian faith offered by the early Heidegger. It shows, first, that Heidegger poses a radical and controversial challenge to philosophers by calling them to do without God in an unfettered pursuit of the question of being (through his ‘destruction of onto-theology’); and, second, that this exclusion nonetheless leaves room for a form of philosophical reflection upon the nature of faith and discourse concerning God, namely for a philosophy of religion in a phenomenological mode (as exemplified most clearly in Heidegger’s 1920/21 lectures on the phenomenology of religious life). However, it is argued that the theological roots of Heidegger’s own phenomenological analyses subvert his frequently asserted claim concerning the incompatibility of Christian faith and philosophical inquiry.
