An investigation into the effects of meditation with children in a Catholic primary school

This article reports on some findings of a small research project that examined the role of meditation in enhancing the relational lives of children, in particular, their relationship with God. It begins by discussing the literature on relevant research studies that investigate different aspects of meditation. The research method in the project was a case study that involved one Catholic primary school in the Melbourne Archdiocese. Different data collecting strategies were utilised, and this article presents and discusses the analysis and findings from one data source – the analysis and interpretation of a drawing activity which was designed to follow one of the weekly meditation exercises that had been observed by the researchers. Finally, the implications of the findings for education and, in particular, religious education are presented.     

Short- and long-term memory are differentially affected by metabolic inhibitors given into hippocampus and entorhinal cortex

Rats were implanted with cannulae in the CA1 area of the dorsal hippocampus or in the entorhinal cortex and trained in one-trial step-down inhibitory avoidance. Two retention tests were carried out in each animal, one at 1.5 h to measure short-term memory (STM) and another at 24 h to measure long-term memory (LTM). The purpose of the present study was to screen the effect on STM of various drugs previously shown to affect LTM of this task when given posttraining at the same doses that were used here. The drugs and doses were the guanylyl cyclase inhibitor LY83583 (LY, 2.5 microMg), the inhibitor of Tyr-protein kinase at low concentrations and of protein kinase G (PKG) at higher concentrations lavendustin A (LAV, 0.1 and 0.5 microMg), the PKG inhibitor KT5823 (2.0 microMg), the protein kinase C (PKC) inhibitor staurosporin (STAU, 2.5 microMg), the inhibitor of calcium/ calmodulin protein kinase II (CaMKII) KN62 (3.6 microMg), the protein kinase A (PKA) inhibitor KT5720 (0.5 microMg), and the mitogen-activated protein kinase kinase (MAPKK) inhibitor PD098059 (PD, 0.05 microMg). PD was dissolved in saline; all the other drugs were dissolved in 20% dimethyl sulfoxide. In all cases the drugs affected LTM as had been described in previous papers. The drugs affected STM and LTM differentially depending on the brain structure into which they were infused. STM was inhibited by KT5720, LY, and PD given into CA1 and by STAU and KT5720 given into the entorhinal cortex. PD given into the entorhinal cortex enhanced STM. LTM was inhibited by STAU, KN62, KT5720, KT5823, and LAV (0.5 microMg) given into CA1 and by STAU, KT5720, and PD given into the entorhinal cortex. The results suggest that STM and LTM involve different physiological mechanisms but are to an extent linked. STM appears to require PKA, guanylyl cyclase, and MAPKK activity in CA1 and PKA and PKC activity in the entorhinal cortex; MAPKK seems to play an inhibitory role in STM in the entorhinal cortex. In contrast, LTM appears to require PKA and PKC activity in both structures, guanylyl cyclase, PKG, and CaMKII activity in CA1, and MAPKK activity in the entorhinal cortex.     

Oral administration of guanosine impairs inhibitory avoidance performance in rats and mice

Extracellular guanine-based purines, mainly the nucleoside guanosine, have recently been shown to exert neuroprotective effects, which seem to be related to antagonism of the glutamatergic system. In this study, we investigated the effects of acute oral administration of guanosine on inhibitory avoidance task in rats and mice. We also studied its effects on locomotor activity, anxiety-related behaviors and mechanisms of action involving the purinergic system. Guanosine (2.0 and 7.5mg/kg, per os), administered 75min pretraining, dose-dependently impaired retention of the inhibitory avoidance task in rats and mice, an effect not prevented by the adenosine receptor antagonist caffeine. Guanosine presented no effects on locomotor activity and anxiety-related behaviors. This amnesic effect of guanosine may be compatible with inhibition of glutamatergic system and seems to be not mediated by adenosine.     

Association of daytime sleepiness and the morningness/eveningness dimension in young adult subjects in Brazil

Sleepiness is a major public health problem associated with motor vehicle crashes, occupational accidents, decreased productivity, and interpersonal problems. It can be influenced by many factors, including the individual's circadian rhythm. The objective of this study is to assess the correlation between the morningness/eveningness dimension and daytime sleepiness in medical school students. This is a cross-sectional study; 310 subjects (123 women and 187 men, M age 20.5 +/- 1.9 yr.) completed a questionnaire on use of drugs, diagnostic diseases, sleeping habits, the Morningness/Eveningness Questionnaire and the Epworth Sleepiness Scale. The only variable related to daytime sleepiness was the morningness/eveningness dimension (r = -.18, p=.002). Questions with higher coefficients of discrimination between the morning and the evening chronotype were "Lying down to rest in the afternoon when circumstances permit" (.61), "Sitting and reading" (.53), and "As a passenger in a car for an hour without a break" (.53). The implications of the findings are discussed.     

Perception of men's personal qualities and prospect of employment as a function of facial hair

The present study investigated the contribution of men's facial hair to impression formation. Participants evaluated photographs of one of four versions of a man--clean shaven, mustached, goateed, or bearded--on a 7-point scale. In Study 1, participants were 106 Brazilian undergraduates (68 men and 38 women). Beardedness was associated with older age, greater responsibility, and leftist political ideas. In Study 2, respondents were 50 Brazilian personnel managers (28 men and 22 women) who made hiring decisions at different companies in the city of Sa? Paulo. Personnel managers clearly preferred clean shaven over bearded, mustached, or goateed men as prospective employees. In a hiring situation for a conservative occupation, a man who signals disposition to conform to rules may be preferred by personnel managers over another who signals nonconformity.     

Mental Health of Parents of Children with Congenital Zika Virus Syndrome in Brazil

This study aims to analyze the potential impact of taking care of a child with congenital Zika virus syndrome (CZS) on the mental health of parents. Specifically, three objectives were formulated: (a) to assess the level of mental health of the parents; (b) to examine the influence of subjective well-being and fatigue as predictors of parents’ mental health; and (c) to identify the impact of sociodemographic variables on parents’ mental health. Sixty-nine mothers (M_age?=?26.38; SD?=?6.23) and 17 fathers (M_age?=?31.41; SD?=?7.57) of children diagnosed with CZS took part in this study. They answered a questionnaire containing measures of positive and negative affects, life satisfaction, fatigue, mental health, as well as sociodemographic questions. The results indicated that approximately 7% of the participants had low levels of mental health and probable emotional disorder. In addition, higher levels of fatigue and negative affects and lower levels of life satisfaction significantly predict a lower level of mental health. Finally, comparative analysis showed significant differences between fathers and mothers: mothers reported experiencing fewer positive and more negative affects, a lower level of satisfaction with life, a higher level of fatigue and worse mental health. In summary, this article presents an overview of the mental health of mothers and fathers of children with CZS and points the way to devising strategies for psychological intervention that promote the adaptation of parents to this kind of developmental disability in the family.     

Is Synthesis of World Religions Possible?

Introduction

All major religions appear to follow a pattern of social contract with an additional feature of ‘termination of the contract’ and its ‘aftermath’, for the soul. This way, religion is known as ‘dissolution mechanism’ (DM). It contains both social and metaphysical terms, where the former is subsidiary to the latter. The metaphysical term is represented by the mokṣa. A given DM not only explicates the state of soul after the termination of contract, but also it endeavours to point out the nature of the ultimate reality it conceives.

Method

DM provides a geometrical/mathematical picture of the universe to locate the ultimate reality and the individual souls in it; three views of the universe—destruction, creation and sustenance—are obtained for three basic religions or thoughts. Buddhist ‘Nothingness’ forms the psychological background for these views of universe. Architectural designs of worship places, yantras or manḍalas, etc., show both the nature of universe and the location of the ultimate in it. Understanding these figures is the key method to be employed for arriving at synthesis.

Conclusion

Synthesis consists in noting the identical common metaphysical generic essence as running through all the religions, and identifying the unique specific root-essence on such a generic essence. Specific root-essence of a given DM consists in the way the unification of cognitions of the universe is carried out. When the unification of all the specific root-essences on the generic essence is carried out with a further psychological background of Buddhism, we get a specimen of metaphysical synthesis of world religions. Thus, synthesis is a distinct and sure possibility.

     

The legitimizing role of accent on discrimination against immigrants

This article analyses the influence of accent on discrimination against immigrants by examining the hypothesis that accent leads to discrimination only in more prejudiced individuals, merely because people speaking with a native accent are perceived to be better qualified than those whose accent is non‐standard. In Study 1 (N = 71), we found that only prejudiced individuals use accent to discriminate against immigrants. In Study 2 (N = 124), we replicated this effect and found that the influence of accent on discrimination is mediated by the perceived quality of the accent. Study 3 (N = 105) replicated the previous results even after controlling for the effect of stereotyping. These results are the first experimental illustration of the hypothesis that accent triggers intergroup discrimination only among prejudiced individuals because they evaluate native accents as being qualitatively better than accents of immigrants, thereby legitimizing ingroup bias.     

Cooperative responding in rats maintained by fixed‐ and variable‐ratio schedules

The present study investigated the effects of fixed‐ratio (FR) and variable‐ratio (VR) reinforcement schedules on patterns of cooperative responding in pairs of rats. Experiment 1 arranged FR 1, FR 10, and VR 10 schedules to establish cooperative responding (water delivery depended on the joint responding of two rats). Cooperative response rates and proportions were higher under intermittent schedules than under continuous reinforcement. The FR 10 schedule generated a break‐and‐run pattern, whereas the VR 10 schedule generated a relatively high and constant rate pattern. Experiment 2 evaluated the effects of parametric manipulations of FR and VR schedules on cooperative responding. Rates and proportions of cooperative responding generally increased between ratio sizes of 1 and 5 but showed no consistent trend as the ratio increased from 5 to 10. Experiment 3 contrasted cooperative responding between an FR6 schedule and a yoked control schedule. Coordinated behavior occurred at a higher rate under the former schedule. The present study showed that external consequences and the schedules under which the delivery of these consequences are based, select patterns of coordinated behavior.
