Opposing amygdala and ventral striatum connectivity during emotion identification

Lesion and electrophysiological studies in animals provide evidence of opposing functions for subcortical nuclei such as the amygdala and ventral striatum, but the implications of these findings for emotion identification in humans remain poorly described. Here we report a high-resolution fMRI study in a sample of 39 healthy subjects who performed a well-characterized emotion identification task. As expected, the amygdala responded to THREAT (angry or fearful) faces more than NON-THREAT (sad or happy) faces. A functional connectivity analysis of the time series from an anatomically defined amygdala seed revealed a strong anticorrelation between the amygdala and the ventral striatum/ventral pallidum, consistent with an opposing role for these regions in during emotion identification. A second functional connectivity analysis (psychophysiological interaction) investigating relative connectivity on THREAT vs. NON-THREAT trials demonstrated that the amygdala had increased connectivity with the orbitofrontal cortex during THREAT trials, whereas the ventral striatum demonstrated increased connectivity with the posterior hippocampus on NON-THREAT trials. These results indicate that activity in the amygdala and ventral striatum may be inversely related, and that both regions may provide opposing affective bias signals during emotion identification.     

The Political Attitudes and Activities of Mainline Protestant Clergy in the Election of 2000: A Study of Six Denominations

This study examines clergy across six mainline Protestant denominations in terms of their social characteristics, their theological positions, and their political attitudes and behavior. The analysis is based on data collected through random surveys of clergy in each denomination conducted in 2001 using the same instrument. The predominant focus of the article is on the nature and level of political activities exhibited by mainline Protestant clergy in the election year of 2000. The analysis revealed that mainline Protestant clergy are indeed relatively active politically, but that, despite their commonality of belonging to the same broad religious tradition, the nature and level of such political activities varies across the six denominations. Variation in the level of political activity is related to a number of different variables. And, while multivariate analysis reduces the number of significant factors that account for such differences, the remaining significant factors are associated with each of the major theoretical approaches that have been advanced to account for differences in participation levels.     

The Mania of Existence: Klein,Winnicott, and Heidegger's Concept of Inauthenticity

This paper offers a new interpretation of Heidegger's concept of inauthenticity (Uneigentlichkeit) in Being and Time. It breaks from the “conformity interpretation” of inauthenticity, according to which the anonymity of the inauthentic person is due to her conformity to das Man. Rather, it argues that the anonymity of the inauthentic person is due to “existential mania” – a state in which a person denies her death and anxiety, understands her abilities to be limitless, and is perpetually active. It shows how this existential mania – and the anonymity to which it gives rise – is analogous to the mania described by the object relations psychoanalyst Melanie Klein. Finally, drawing on D. W. Winnicott's discussion of mania, it shows how both the inauthentic person's conformity to das Man, and her existential mania, give rise to anonymity.     

Relations between Parenting Stress,Parenting Style,and Child Executive Functioning for Children with ADHD or Autism

Relations among parenting stress, parenting style, and child executive functioning for children with disabilities are not easily teased apart. The current study explored these relations among 82 children and adolescents age 7–18: 21 with attention deficit/hyperactivity disorder, 33 with autism spectrum disorder, and 28 typically developing. Results indicated that children with attention deficit/hyperactivity disorder or autism spectrum disorder had more executive functioning deficits, and their parents reported more parenting stress and a greater use of permissive parenting, compared to typically developing children. In general, increased parenting stress was associated with greater use of authoritarian and permissive parenting styles, as well as more problems with behavior regulation for children. Authoritarian and permissive parenting styles were associated with poorer child executive functioning. Child diagnostic group (attention deficit/hyperactivity disorder, autism spectrum disorder, typically developing) moderated relations between parent stress and child functioning, and between parenting style and child functioning. Implications for intervention with families of children with disabilities are discussed.     

Understanding smoking after acute illness: An application of the sentinel event method

The sentinel event theory provides a stepwise approach for building models to understand how negative events can spark health behaviour change. This study tested a preliminary model using the sentinel events method in a sample (N = 300) of smokers who sought care for acute cardiac symptoms. Patients completed measures on: smoking-related causal attribution, perceived severity of the acute illness event, illness-related fear and intentions to quit smoking. Patients were followed up one week after the health event and a seven-day timeline follow back was completed to determine abstinence from tobacco. Structural equation models were performed using average predictor scale scores at baseline, as well as three different time anchors for ratings of illness severity and illness-related fear. Quit intentions, actual illness severity and age were the consistent, positive and independent predictors of seven-day point prevalence abstinence. Additional research on the influences of perceptions and emotional reactions is warranted.     

Perceiving the intensity of light

The relationship between luminance (i.e., the photometric intensity of light) and its perception (i.e., sensations of lightness or brightness) has long been a puzzle. In addition to the mystery of why these perceptual qualities do not scale with luminance in any simple way, "illusions" such as simultaneous brightness contrast, Mach bands, Craik-O'Brien-Cornsweet edge effects, and the Chubb-Sperling-Solomon illusion have all generated much interest but no generally accepted explanation. The authors review evidence that the full range of this perceptual phenomenology can be rationalized in terms of an empirical theory of vision. The implication of these observations is that perceptions of lightness and brightness are generated according to the probability distributions of the possible sources of luminance values in stimuli that are inevitably ambiguous.     

Absolutely general knowledge*

There is extensive debate among contemporary philosophers about the possibility of absolutely unrestricted quantification; thus far, the debate been almost entirely logically and metaphysically focused. We argue for a third axis of evaluation: the epistemological. We defend absolutism on epistemological grounds, by showing that one prominent and attractive alternative to absolutism—schematism—is epistemologically unacceptable. First, we spell out and motivate an epistemological desideratum for theories of generality, a desideratum which is easily satisfied by absolutists. Second, we consider five ways the schematist might satisfy this desideratum. We argue that none of the five ways is successful.     

Screening for Suicidal Ideation and Attempts among Emergency Department Medical Patients: Instrument and Results from the Psychiatric Emergency Research Collaboration

Joint Commission National Patient Safety Goal 15 calls for organizations “to identify patients at risk for suicide.” Overt suicidal behavior accounts for 0.6% of emergency department (ED) visits, but incidental suicidal ideation is found in 3%–11.6%. This is the first multicenter study of suicide screening in EDs. Of 2,243 patients in six diverse emergency settings, 1,068 (47.7%) were screened with a brief instrument. Depression was endorsed by 369 (34.5%); passive suicidal ideation by 79 (7.3%); and active suicidal ideation by 24 (2.3%). One hundred thirty‐seven (12.8%) reported prior attempts, including 35 (3.3%) with current suicidal ideation. Almost half of those with current ideation had a prior attempt (43.8%) versus those without current ideation, 10.3%, χ² (1) = 75.59, p < .001. Twenty cases (25%) were admitted to medical services, but only 10 (12.5%) received mental health assessment; none were admitted directly to a psychiatry service. The prevalence of suicidal ideation here is similar to previous studies but the frequency of prior attempts has not been reported. The 35 cases with current ideation and prior attempt are at risk. As they did not present psychiatrically, they would likely have gone undetected. Despite reporting these cases to clinical staff, few received risk assessment.
