Connecting terror management and dissonance theory: Evidence that mortality salience increases the preference for supporting information after decisions

From the perspective of terror management theory, reminders of mortality should intensify the desire to pursue cognitive consistency. The authors investigated this notion with regard to dissonance theory starting from the finding of research on "selective exposure to information" that after having made a decision, people prefer consonant over dissonant information. The authors found that following mortality salience, people indeed showed an increased preference for information that supported their decision compared to information conflicting with it. However, this only occurred with regard to a worldview-relevant decision case. For a fictitious decision scenario, mortality salience did not affect information seeking. Practical and theoretical implications are discussed.     

Amnesic effect of GMP depends on its conversion to guanosine

Extracellular guanine-based purines, namely the nucleotides GTP, GDP, GMP and the nucleoside guanosine, exert important neuroprotective and neuromodulator roles in the central nervous system, which may be related to inhibition of the glutamatergic neurotransmission activity. In this study, we investigated GMP effects on mice inhibitory avoidance performance and the dependence on its conversion to guanosine for such effect, by using the ecto-5'-nucleotidase specific inhibitor AOPCP. We also investigated if this conversion occurs in the central nervous system or peripherally, and if guanosine and GMP affect nociception by the tail-flick test. I.p. GMP or guanosine (7.5 mg/kg) or i.c.v. GMP (480 nmol) pretraining administration was amnesic for the inhibitory avoidance task. I.c.v. AOPCP (1 nmol) administration completely reversed the amnesic effect of i.c.v. GMP, but not of i.p. GMP, indicating that peripheral conversion of GMP to guanosine is probably relevant to this effect. AOPCP alone did not interfere with the performance. Furthermore, tail-flick measurement was unaffected by i.p. GMP and guanosine, suggesting that the amnesic effect of both purines was not due to some antinociceptive effect against the footshock used in the task. All these data together, in accordance to those previously observed in studies involving glutamate uptake and seizures reinforce the idea that guanosine is the specific extracellular guanine-based purines effector and indicate that its conversion occurs not only in the central nervous system but also peripherally.     

rCBF/SPECT in the evaluation of inner-city minority patients with a history of impaired memory: a pilot blind read pre- and poststudy

Eight patients (seven women), mean +/- SD T1 age 68.57 +/- 12.43 years, average educational level 5.83 +/- 3.70 years, had two Tc-99m ECD SPECT examinations separated by an average 8.49 +/- 5.59 months. Patients were imaged using standard Harlem Hospital acquisition and processing protocols with approximately 30 mCi of ECD on a Prism 3000 triple head gamma camera. Images were interpreted by an independent reader blinded to the patients' clinical history and imaging date. T1 psychiatric diagnosis was seven Alzheimer's dementia (AD) and one depression. Eight T1 images were interpreted as abnormal, six indicative of AD. Binomial 95% two-tail confidence interval for T1 agreement between diagnosis and interpretation was 0.25 0.63 0.92. T2 diagnosis was seven AD and one none. Seven T2 images were abnormal and indicative of AD, and one was normal. T2 confidence interval was 0.34 0.75 0.97. These findings suggest SPECT's value in assessing AD in uneducated socioeconomically disadvantaged geriatric patients.     

Production of recrystallized nano-grains in a fine-grained Cu–Zn alloy

A fine-grained Cu–30%Zn alloy sheet was rolled at 77 K to induce ultrafine mechanical twins. Subsequent annealing of the rolled alloy at temperatures up to 543 K led to the uniform appearance of recrystallized ultrafine grains (UFGs), which contained numerous annealing twins. Average grain sizes of 150 ～ 300 nm were produced in this way. The formation of such UFGs during annealing is attributed to the high nucleus density associated with the fine initial grain size as well as to the high densities of mechanical twins and dislocations produced by cryorolling. The high driving force for recrystallization enabled the use of relatively low annealing temperatures, which limited the subsequent grain growth.     

The role of practice and habituation in Socrates’ theory of ethical development

ABSTRACT

The goal of this paper is to challenge the standard view that Socrates of the early Platonic dialogues is an intellectualist with respect to virtue. Through a detailed analysis of the educational theory laid out in the early dialogues, it will be argued that Socrates believes that the best way to cultivate virtues in his interlocutors is not to convince them of ethical truths by way of reason and argument alone, but to encourage them to participate in the practice of virtue. Habit and practice are essential to the cultivation of virtue because they mould the desires and dispositions of the agent and promote a kind of knowledge that cannot be achieved discursively – craft-knowledge. Only when agents have achieved craft-knowledge can they be counted on to act virtuously on every occasion; and craft-knowledge can only be achieved by way of practice and habituation.     

Prodigal Sons: Dual Abrahamic Categorization Mediates the Detrimental Effects of Religious Fundamentalism on Christian–Muslim Relations

Religious fundamentalism is associated with Christian–Islamic conflicts globally, but the psychological reasons remain unexplored. Here, we show that fundamentalism is detrimental to interreligious relations because it makes Christians and Muslims alike reject common theological grounds and Abrahamic origins. Specifically, Study 1 demonstrated that such dual Abrahamic categories mediated the negative effects of fundamentalism on real monetary donations to outgroup children desperately in need (i.e., Save the Children Syria) among Christians but not Atheists. Of importance, this was the case only to the degree that Syrian children were perceived as Muslims and, hence, as part of an Abrahamic outgroup. Using a double-randomized experimental design, Study 2 demonstrated the causal effects of religious fundamentalism on Abrahamic categorization and of Abrahamic categorization on mutual resource distribution bias among Muslims and Christians. Together, these studies suggest that religious fundamentalism fuels interreligious conflicts because it crucially impacts basic categorization processes, with subsequent negative effects on intergroup relations.     

Sexism,rape myths and feminist identification explain gender differences in attitudes toward the #metoo social media campaign in two countries

ABSTRACT

On October 15, 2017, actress Alyssa Milano popularized the #metoo campaign, which sought to expose the prevalence of sexual harassment and assault in public domains by encouraging victims to share their experiences on social media using the hashtag metoo. The online campaign rapidly grew to a global phenomenon, which was generally well supported. However, some criticized the campaign online as a battle of the sexes, which pits men against women. Our cross-cultural research investigated whether gender differences in attitudes and feelings toward #metoo are due to underlying differences in ideologies and experiences that only partly overlap with gender. We surveyed respondents in the United States, where the campaign began, and in Norway, a highly gender-egalitarian country. In both countries, men expressed less positivity toward #metoo than women and perceived it as substantially more harmful and less beneficial. These gender differences were largely accounted for by men being higher than women in hostile sexism, higher in rape myth acceptance, and lower in feminist identification. The results, hence, suggest that gender differences in attitudes to social media campaigns such as #metoo might be best characterized as dimensional ideological differences rather than fundamental group differences.     

Narrative retelling in children with neurodevelopmental disorders: Is there a role for nonverbal temporal‐sequencing skills?

Oral narrative retelling is often problematic for children with communicative and neurodevelopmental disorders. However, beyond a suggested role of language level, little is known about the basis of narrative performance. In this study we examine whether oral narrative retelling might be associated not just with language level but also with skills related to nonverbal narrative temporal sequencing. A diagnostically heterogeneous sample of Swedish‐speaking children with a full scale IQ >70 was included in the study (N = 55; age 6–9 years). Narrative retelling skills were measured using the three subscores from the bus story test (BST). Independent predictors included (1) temporal sequencing skills according to a picture arrangement test and (2) a language skills factor consisting of definitional vocabulary and receptive grammar. Regression analyses show that language skills predicted BST Sentence Length and Subordinate Clauses subscores, while both temporal sequencing and language were independently linked with the BST Information subscore. When subdividing the sample based on nonverbal temporal sequencing level, a significant subgroup difference was found only for BST Information. Finally, a principal component analysis shows that temporal sequencing and BST Information loaded on a common factor, separately from the language measures. It is concluded that language level is an important correlate of narrative performance more generally in this diagnostically heterogeneous sample, and that nonverbal temporal sequencing functions are important especially for conveying story information. Theoretical and clinical implications are discussed.     

Automatic Behavior – Its Social Embedding and Individual Consequences

Automatic behavior, that is, the non‐conscious activation of perceiver behavior by social category priming, has undergone considerable development in the recent years. While initial effects pointed to often rather surprising effects that could be characterized as imitation of the behavior of the social category itself, current research unfolds a much more complex picture. Not only imitative behavior but, contrasting, also response behavior is getting activated. Response behavior is fundamentally different from imitation and contrast and denotes behavior that is directed toward the social category out of the action ecology of the perceiver. Furthermore, boundary conditions have been established and could reveal that motivation (goals) and social context modulate the selection of specific automatic responses. Most recent findings reveal that social category priming embedded in context also modulates visual attention patterns pertaining to means functional for the response behavior. Similar to the increased complexity of findings, the proposed underlying explanatory models have developed in comprehensiveness. Taken together, automatic behavior now has to be seen as a valid form of social influence, and its benefits and pitfalls are further to be investigated.
