Process timing and its relation to the coding of tonal harmony

Advances in auditory research suggest that gamma-band synchronization of frequency-specific cortical loci could be responsible for the integration of pure tones (harmonics) into harmonic complex tones. Thus far, evidence for such a mechanism has been revealed in neurophysiological studies, with little corroborative psychophysical evidence. In six experiments, we observed a rate- and time-specific response-time advantage for a sequence of target pips when the defining frequency of the target was a fractional multiple of a priming frequency. The effect was only observed when the prime and target sequences were presented at 33 pips per second and when the interstimulus interval was approximately 100 and 250 ms. This evidence implicates oscillatory gamma-band activity in the representation of harmonic complex tones and suggests that synchronization with precise temporal characteristics is important for disambiguating related harmonic templates. An outline of a model is presented, which accounts for these findings in terms of fast resynchronization of relevant neuronal assemblies.     

Autonomy,Reciprocity, and Responsibility: Darwall and Levinas on the Second Person

Abstract

Stephen Darwall’s The Second‐Person Standpoint converges with Emmanuel Levinas’s concern about the role of the second‐person relationship in ethics. This paper contrasts their methodologies (regressive analysis of presuppositions versus phenomenology) to explain Darwall’s narrower view of ethical experience in terms of expressed reactive attitudes. It delineates Darwall’s overall justificatory strategy and the centrality of autonomy and reciprocity within it, in contrast to Levinas’s emphasis on the experience of responsibility. Asymmetrical responsibility plays a more foundational role as a critical counterpoint to ‘mean‐spirited’ reciprocity than Darwall’s laudable distinction between accountability and revenge, and responsibility even founds this distinction. The experience of being summoned to asymmetrical responsibility amplifies the meaning of ‘authority’, which is a presupposition for Darwall. Finally, asymmetrical responsibility helps develop decentred reasoning, invites risk beyond the boundaries of reciprocity at moments when autonomy appears endangered, reconciles respect and care at the experiential level, and presses to extend the scope of moral obligation.     

Pragmatic Psychodynamic Psychotherapy—Bridging Contemporary Psychoanalytic Clinical Practice and Evidence-Based Psychodynamic Practice

Pragmatic psychodynamic psychotherapy (PPP; Summers & Barber, 2009 Barber, J. P. 2009. Toward a working through of some core conflicts in psychotherapy research. Psychother. Res, 19(1): 1–12. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) describes the therapeutic principles and approaches found in many forms of manualized psychodynamic psychotherapies, which are being used in research studies with the aim of building an evidence-based psychodynamic practice. This article focuses on one such treatment, Supportive-expressive psychotherapy (SEP; Luborsky 1984), which employs the Core Conflictual Relationship Theme (CCRT) method to formulate core interpersonal problems and treatment goals and identify therapeutic interventions. To illustrate SEP, we describe the 40-session treatment of a patient who met diagnostic criteria for several personality disorders. The case illustrates how complex ego-syntonic character pathology is expressed in CCRT terms and worked through in the transference, gradually becoming ego-dystonic and amenable to modification. In this case, the patient became more aware of his interpersonal wishes and vulnerability. Although his anxiety increased somewhat, he had an improvement in psychosocial functioning.     

Younger and older adults’ collaborative recall of shared and unshared emotional pictures

Although a group of people working together recalls more items than any one individual, they recall fewer unique items than the same number of people working apart whose responses are combined. This is known as collaborative inhibition, and it is a robust effect that occurs for both younger and older adults. However, almost all previous studies documenting collaborative inhibition have used stimuli that were neutral in emotional valence, low in arousal, and studied by all group members. In the current experiments, we tested the impact of picture-stimuli valence, picture-stimuli arousal, and information distribution in modulating the magnitude of collaborative inhibition. We included both younger and older adults because there are age differences in how people remember emotional pictures that could modulate any effects of emotion on collaborative inhibition. Results revealed that when information was shared (i.e., studied by all group members), there were robust collaborative inhibition effects for both neutral and emotional stimuli for both younger and older adults. However, when information was unshared (i.e., studied by only a single group member), these effects were attenuated. Together, these results provide mixed support for the retrieval strategy disruption account of collaborative inhibition. Supporting the retrieval strategy disruption account, unshared study information was less susceptible to collaborative inhibition than shared study information. Contradicting the retrieval strategy disruption account, emotional valence and arousal did not modulate the magnitude of collaborative inhibition despite the fact that participants clustered the emotional, but not neutral, information together in memory.     

Psychometric properties of the mobility inventory for agoraphobia: convergent, discriminant, and criterion-related validity

Aims of this study were (a) to summarize the psychometric literature on the Mobility Inventory for Agoraphobia (MIA), (b) to examine the convergent and discriminant validity of the MIA's Avoidance Alone and Avoidance Accompanied rating scales relative to clinical severity ratings of anxiety disorders from the Anxiety Disorders Interview Schedule (ADIS), and (c) to establish a cutoff score indicative of interviewers’ diagnosis of agoraphobia for the Avoidance Alone scale. A meta-analytic synthesis of 10 published studies yielded positive evidence for internal consistency and convergent and discriminant validity of the scales. Participants in the present study were 129 people with a diagnosis of panic disorder. Internal consistency was excellent for this sample, α = .95 for AAC and .96 for AAL. When the MIA scales were correlated with interviewer ratings, evidence for convergent and discriminant validity for AAL was strong (convergent r with agoraphobia severity ratings = .63 vs. discriminant rs of .10–.29 for other anxiety disorders) and more modest but still positive for AAC (.54 vs. .01–.37). Receiver operating curve analysis indicated that the optimal operating point for AAL as an indicator of ADIS agoraphobia diagnosis was 1.61, which yielded sensitivity of .87 and specificity of .73.     

Who are the Owners of Firearms Used in Adolescent Suicides?

In this brief report, the source of firearms used in adolescent suicides was examined using data from the National Violent Injury Statistics System, the pilot to the CDC's National Violent Death Reporting System, a uniform reporting system for violent and firearm-related deaths. Data represent the 63 firearm suicides among youth (<18 yrs) that occurred in 2001 or 2002 in one of four states (CT, ME, UT, WI) or two metropolitan counties (San Francisco, CA; Allegheny County, PA). Four-fifths of the suicides took place in the decedents' homes, and--when the firearm owner was known--most of the firearms were owned by parents. Findings replicate results from previous research and highlight the importance of limiting youth access to firearms.     

Why is violent crime so common in the Americas?

Violent crimes, including murders, rapes, and assaults are substantially higher in the Americas than other regions of the world. This study investigated the role of single parenthood ratios in accounting for this regional variation in violent crime of 39 countries using INTERPOL data. It pitted the prediction of parental investment (calling for a delayed relationship between single parenthood and crime) against a mating aggression hypothesis that predicted a contemporaneous effect. Regression analyses found that current single parenthood ratios were strongly and consistently predictive of violent crimes whereas single parenthood ratios 18 years earlier were not and this conclusion remained following controls for income inequality and the population sex ratio. The results indicate that the regional difference in violent crime is best explained in terms of mating competition rather than reduced parental investment. Aggr.
