The German Adaptation and Standardization of the Personality Assessment Inventory (PAI)

We developed the German Adaptation of the Personality Assessment Inventory (PAI; Morey, 1991) under careful consideration of current adaptation literature and guidelines. The adaptation process included the translation of the 344 items into German, a back translation into English as well as the testing of the language equivalence using a bilingual sample. We then standardized the final German version of the PAI for the German population. We compared the American and German norm and reliability data. The observed differences in PAI scale means did not exceed 5 T scores. Internal consistency reliability showed a similar pattern in both language versions, although the German alpha coefficients were on average slightly lower than the American ones. Factor structure was similar in both versions. We discuss expectations about the German PAI and possible problems for its practical usefulness for the German-speaking population.     

The effect of the NMDA receptor antagonist MK-801 on the acquisition and extinction of learned fear in the developing rat

Recent findings reveal qualitative developmental differences in extinction of learned fear. The present study explored potential developmental differences in the role of NMDA in acquisition and extinction. Rats were injected with MK-801 prior to fear conditioning or extinction training. Acquisition was found to be NMDA dependent in both age groups, whereas extinction was found to be NMDA dependent in 23-day-old rats, but NMDA independent in 16-day-old rats. These results illustrate another fundamental developmental difference in extinction as well as a dissociation in the role of NMDA in the acquisition and extinction of fear early in development.     

Action–effect learning in early childhood: does language matter?

Previous work showed that language has an important function for the development of action control. This study examined the role of verbal processes for action–effect learning in 4-year-old children. Participants performed an acquisition phase including a two-choice key-pressing task in which each key press (action) was followed by a particular sound (effect). Children were instructed to either (1) label their actions along with the corresponding effects, (2) verbalize task-irrelevant words, (3) or perform without verbalization. In a subsequent test phase, they responded to the same sound effects either under consistent or under inconsistent sound-key mappings. Evidence for action–effect learning was obtained only if action and effects were labeled or if no verbalization was performed, but not if children verbalized task-irrelevant labels. Importantly, action–effect learning was most pronounced when children verbalized the actions and the corresponding effects, suggesting that task-relevant verbal labeling supports the integration of event representations.     

Effects of exposure of mice to hindlimb unloading on leukocyte subsets and sympathetic nervous system activity

The hindlimb unloading (HU) rodent model was developed to simulate some of the aspects of spaceflight conditions. Our previous studies showed that exposure to HU for 48 h (h) followed by bacterial challenge, reduces the ability of mice to resist infection. The purpose of this study was to investigate the physiological changes in mice during the 48 h of exposure to HU to understand the mechanisms involved in the increased susceptibility to infection observed in mice subjected to these conditions. Female Swiss Webster mice were hindlimb-unloaded during 48 h. Blood samples, spleen and peritoneal cells were removed before and after 18 or 48 h of HU-exposure. Leukocyte subset analysis was performed in spleen and peritoneal cells by flow cytometry, and catecholamine levels were measured in plasma and whole spleen by a catecholamine enzyme immunoassay. Catecholamine levels measured in plasma and spleen were significantly greater in mice exposed to HU compared to control. This increase coincided with significant reductions in spleen size in the HU group. Flow cytometric analyses showed a significant reduction of splenic CD19 + B-cells and NK1.1+ cells in mice exposed to HU with a concomitant increase in T-cells. These results suggest that exposure to HU increases the activity of the sympathetic nervous system (SNS) and induces lymphocyte sub-population changes that may contribute to the deregulation of immunity seen in mice exposed to HU and, more importantly may predispose the otherwise healthy host to the subsequent reduced ability to resist infections.     

Emotions induced by operatic music: psychophysiological effects of music, plot, and acting: a scientist's tribute to Maria Callas

Operatic music involves both singing and acting (as well as rich audiovisual background arising from the orchestra and elaborate scenery and costumes) that multiply the mechanisms by which emotions are induced in listeners. The present study investigated the effects of music, plot, and acting performance on emotions induced by opera. There were three experimental conditions: (1) participants listened to a musically complex and dramatically coherent excerpt from Tosca; (2) they read a summary of the plot and listened to the same musical excerpt again; and (3) they re-listened to music while they watched the subtitled film of this acting performance. In addition, a control condition was included, in which an independent sample of participants succesively listened three times to the same musical excerpt. We measured subjective changes using both dimensional, and specific music-induced emotion questionnaires. Cardiovascular, electrodermal, and respiratory responses were also recorded, and the participants kept track of their musical chills. Music listening alone elicited positive emotion and autonomic arousal, seen in faster heart rate, but slower respiration rate and reduced skin conductance. Knowing the (sad) plot while listening to the music a second time reduced positive emotions (peacefulness, joyful activation), and increased negative ones (sadness), while high autonomic arousal was maintained. Watching the acting performance increased emotional arousal and changed its valence again (from less positive/sad to transcendent), in the context of continued high autonomic arousal. The repeated exposure to music did not by itself induce this pattern of modifications. These results indicate that the multiple musical and dramatic means involved in operatic performance specifically contribute to the genesis of music-induced emotions and their physiological correlates.     

Health disparities between binary and non binary trans people: A community-driven survey

Abstract

Background: Genderqueer and nonbinary () people have remained largely invisible in health research. Previous research shows worse outcomes on health indicators for trans people when compared with cisgender controls, but the differences between binary trans and GQNB individuals are inconclusive.

Aims: To compare overall health and well-being of GQNB people with controls of trans men and trans women, taking into account the impact of the additive effect of their socio-economic position, as well as their current need for gender affirming medical interventions.

Methods: A community-driven survey was conducted in 2016 in five countries (Georgia, Poland, Serbia, Spain, and Sweden). Self-reported health and general well-being were analysed for differences between binary trans and GQNB respondents. The effects of multiple control variables (age, economic situation, educational level, belonging to an ethnic, religious, sexual or ability minority group, sex assigned at birth) as well as the current need for gender affirming medical interventions were controlled for.

Results: The sample consisted of 853 respondents aged 16 and older, with 254 trans women (29.8%), 369 trans men (43.2%), and 230 GQNB people (26%). GQNB respondents showed significantly worse self-reported health and worse general well-being in comparison to binary trans respondents. Additional negative impacts of having a lower educational level, having more economic stress, and belonging to a disability minority group were found. Being in need of gender affirming medical interventions contributed significantly to worse self-reported health, whereas being younger contributed to worse general well-being.

Discussion: In understanding health disparities between binary trans and GQNB people, it is necessary to take into account the additive effect of multiple socio-economic positions, and the current need for gender affirming medical interventions. The high proportion of GQNB respondents who report worse health outcomes highlights the need for policy makers and health-care providers in creating nonbinary-inclusive environments.     

Fit for persuasion: the effects of nonverbal delivery style,message framing,and gender on message effectiveness

This study examined two experimental variables, delivery style and message framing, that have yet to be examined together in the regulatory fit literature. College students (mean age = 30) watched a video message encouraging regular exercise delivered in an eager or vigilant nonverbal style and framed in terms of gain or loss. Results revealed significant fit effects involving gender, delivery style, and message framing. The eager message was perceived as more effective by men whereas the vigilant message was perceived as more effective by women. A message framing by delivery style fit effect also emerged for perceived message effectiveness. The implications and limitations of these findings are discussed.     

An Egalitarian Argument against Reducing Deprivation

Deprivations normally give rise to undeserved inequality. It is commonly thought that one way of improving a situation with respect to equality is by reducing the incidence of deprivations. In this paper I argue that there is at least one respect in which reducing the incidence of deprivations can make things worse from the point of view of equality. While eliminating deprivations leads to the elimination of inequalities, reducing the incidence of deprivations leads to an uneven distribution of the pairwise relations of inequality of a population, which leads to the concentration of pairwise relations of inequality in the worse off. If my argument is correct, egalitarians have reasons to broaden their dimensions of concern: egalitarians should not only be concerned about the unequal distribution of goods, but also about the unequal distribution of pairwise relations of inequality of a population.     

Early Temperament and Attachment Security with Mothers and Fathers as Predictors of Toddler Compliance and Noncompliance

This longitudinal study (n = 106) examined associations between temperament, attachment, and styles of compliance and noncompliance. Infant negative temperamental reactivity was reported by mothers at 3, 5 and 7 months. Infant attachment was assessed (Strange Situation) at 12 (mothers) and 14 months (fathers). Toddlers' styles of compliance/noncompliance were measured using two laboratory contexts (clean‐up/delay) at 20 months. Results indicated that temperament and attachment predicted toddler behaviour. Toddlers who were secure with mothers and low in temperamental negative reactivity showed more committed compliance than those who were insecure and low in negative reactivity or secure and high in negative reactivity. In addition, interactions revealed that relations between infant–mother attachment and defiance depended on infant–father attachment security, temperament and context. Findings highlight the differential and complex roles of temperament and attachment as potential precursors of later social competence. Copyright © 2013 John Wiley & Sons, Ltd.
