Neuropsychological function and past exposure to metallic mercury in female dental workers

The aim of this study was to see if dental personnel with previous exposure to metallic mercury have later developed disturbances in cognitive function. Ninety-one female participants who had been selected from a previous health survey of dental personnel were investigated neuropsychologically within the following domains: motor function, short-term memory, working memory, executive function, mental flexibility, and visual and verbal long-term memory. The scores were mainly within normal ranges. Relationships between an exposure score, the duration of employment before 1990, and previously measured mercury in urine as independent variables and the neuropsychological findings as dependent variables, were analyzed by multiple linear regression controlling for age, general ability, length of education, alcohol consumption, and previous head injuries. The only relationship that was statistically significant in the hypothesized direction was between the previously measured urine mercury values and visual long-term memory, where the urine values explained 30% of the variability. As the study had a low statistical power and also some other methodological limitations, the results have to be interpreted with caution. Even so, we think it is right to conclude that neuropsychological findings indicative of subsequent cognitive injuries are difficult to find in groups of otherwise healthy dental personnel with previous occupational exposure to mercury.     

Motor intentionality and the case of Schneider

I argue that Merleau-Ponty’s use of the case of Schneider in his arguments for the existence of non-conconceptual and non-representational motor intentionality contains a problematic methodological ambiguity. Motor intentionality is both to be revealed by its perspicuous preservation and by its contrastive impairment in one and the same case. To resolve the resulting contradiction I suggest we emphasize the second of Merleau-Ponty’s two lines of argument. I argue that this interpretation is the one in best accordance both with Merleau-Ponty’s general methodology and with the empirical case of Schneider as it was described by Gelb and Goldstein.

Prevalence of auditory verbal hallucinations in a general population: A group comparison study

The present study was specifically designed to investigate the prevalence of auditory verbal hallucinations (AVH) in the general population, and sought to compare similarities and differences regarding socio‐demographics, mental health and severe life events between individuals who have never experienced AVH with those who had. The study also aimed to compare those who sought professional help for their experience of AVH with those who had not sought help. Through a postal questionnaire, 2,533 participants ages 18 and over from a national survey completed the Launay‐Slade Hallucinations Scale and other measures examining AVH characteristics and other areas related to AVH. In total, 7.3% of the sample reported a life‐time prevalence of AVH. Those with AVH were more likely to be single and unemployed, reported higher levels of depression and anxiety, and experienced a higher number of severe life events compared with those without AVH. Only 16% of those who experienced AVH in the general population sought professional help for these experiences. Compared to those who did not seek professional help, participants that had were more likely to experience AVH with a negative content, experience them on a daily basis, undergo negative reactions when experiencing AVH, and resist AVH. In conclusion, the prevalence of AVH was found to be relatively high. The results also revealed higher levels of reduced mental health for individuals who sought professional help, followed by those who did not, compared with those who had never experienced AVH.     

Nightmares, Bad Dreams, and Emotion Dysregulation: A Review and New Neurocognitive Model of Dreaming

ABSTRACT— Nightmares—vivid, emotionally dysphoric dreams—are quite common and are associated with a broad range of psychiatric conditions. However, the origin of such dreams remains largely unexplained, and there have been no attempts to reconcile repetitive traumatic nightmares with nontraumatic nightmares, dysphoric dreams that do not awaken the dreamer, or with more normative dreams. Based on recent research in cognitive neuroscience, sleep physiology, fear conditioning, and emotional-memory regulation, we propose a multilevel neurocognitive model that unites waking and sleeping as a conceptual framework for understanding a wide spectrum of disturbed dreaming. We propose that normal dreaming serves a fear-extinction function and that nightmares reflect failures in emotion regulation. We further suggest that nightmares occur as a result of two processes that we term affect load—a consequence of daily variations in emotional pressures—and affect distress—a disposition to experience events with high levels of negative emotional reactivity.     

In Defence of Conceptual Integration

According to the ‘integration approach’, interpretations of political concepts should (1) explain that they stand for rights we ought to respect and (2) be both compatible and mutually supporting. I start by clarifying what this means, and proceed to an examination of Ronald Dworkin’s latest argument for value holism. I argue that his argument fails to provide a convincing case for the integration approach. I go on to argue that we nonetheless should accept that interpretations of political concepts should be compatible, because denying it would be inconsistent with (1), and the fact that ‘ought implies can’. I then provide reasons for thinking that we also cannot really satisfy (1) for any particular concept without giving reasons in term of what fall under other concepts—that is, interpreting the concepts as mutually supporting. We thus have reasons to accept both parts of (2). Finally, I defend the integration approach from three important objections: First, that it conflates different values; secondly, that it is inconsistent with ordinary language-usage; and thirdly, that it overlooks important telic values. I conclude that none of these compels us to abandon the integration approach.     

Norwegian version of the automatic thoughts questionnaire: a reliability and validity study

This study investigated the reliability and validity of the Norwegian version of the Automatic Thoughts Questionnaire. Three samples were used: (a) 344 male military recruits; (b) 142 psychiatric outpatients; and (c) 41 healthy controls. The Automatic Thoughts Questionnaire was found to have high internal consistency and satisfactory temporal stability. It correlated positively with the Beck Depression Inventory and was found to discriminate significantly between clinically depressed and non-depressed psychiatric patients and healthy controls. In general the results are satisfactory, suggesting that the Norwegian version of the Automatic Thoughts Questionnaire has adequate reliability and validity properties. The Automatic Thoughts Questionnaire was shown to be a useful measure of frequency of automatic negative thoughts in both clinical and non-clinical populations.     

Divergence over conformity: Change in immigration attitudes after the electoral success of an anti‐immigration populist party in the Finnish 2015 parliamentary elections

The populist, anti‐immigration‐oriented Finns Party was considered the winner of the Finnish 2015 parliamentary elections. In a representative sample of young adults (N = 606), a longitudinal pre‐ post‐election design revealed that attitudes towards immigration became more favourable among those disappointed by the outcome and those who did not vote for the Finns Party. Among the latter, both supporting the green‐red rival parties and disliking the Finns Party independently predicted increased support for migration. Other attitudes did not change. The results highlight the importance of social processes and identity concerns, particularly self‐categorization, as drivers of attitude change. While previous work has focused on conformity dynamics, our results suggest that diverging from an unwanted identity may be associated with attitude change.     

With a Spirit that Understands: Reflections on a Long‐term Community Science Initiative to End Suicide in Alaska

This retrospective analysis of a long‐term community‐based participatory research (CBPR) process spans over two decades of work with Alaska Native communities. A call to action from Alaska Native leadership to create more effective strategies to prevent and treat youth suicide and alcohol misuse risk initiated a response from university researchers. This CBPR process transformed into a collaborative effort to indigenously drive and develop solutions through research. The People Awakening project started our team on this translational and transformational pathway through community intervention science in the Central Yup'ik region of Alaska. We examine more deeply the major episodes and their successes and struggles in maintaining a long‐term research relationship between university researchers and members of Yup'ik Alaska Native communities. We explore ways that our CBPR relationship has involved negotiation and engagement with power and praxis, to deepen and focus attention to knowledge systems and relational elements. This paper examines these deeper, transformative elements of our CBPR relationship that spans histories, cultures, and systems. Our discussion shares vignettes from academic and community perspectives to describe process in a unique collaboration, reaching to sometimes touch upon rare ground in emotions, tensions, and triumphs over the course of a dozen grants and twice as many years. We conclude by noting how there are points where, in a long‐term CBPR relationship, transition out of emergence into coalescing and transformation can occur.     

The Impact of Racial Microaggressions on Mental Health: Counseling Implications for Clients of Color

This study examined the relationship between racial microaggressions (subtle and unintentional forms of racial discrimination) and mental health. Results from a large sample (N = 506) indicated that higher frequencies of racial microaggressions negatively predicted participants' mental health and that racial microaggressions were significantly correlated with depressive symptoms and negative affect. Differences in the types of microaggressions experienced by various racial groups (Asian, Latina/o, Black, White, and multiracial) and counseling implications are discussed.
