The sensory‐cognition association in adulthood: Different magnitudes for processing speed,inhibition, episodic memory,and false memory?

One hundred and forty-six participants (age range = 20-80) completed a battery of tests designed to measure visual acuity, processing speed, inhibition, episodic memory and false memory. The relations between visual acuity and general cognitive ability, as well as between visual acuity and the indicators of this construct, were evaluated with structural equation modeling. The measurement model confirmed that the indicators of the individual cognitive abilities could be grouped into a general cognitive functioning factor. However, the relation between episodic and false memory was not completely explained by the shared association with this general factor. Furthermore, visual acuity predicted approximately half of the age-related variance in the general cognition factor. Also, the proportion of age-related variance shared with vision was highest in inhibition and lowest in false memory. The results are discussed in the light of common cause accounts of cognitive aging.     

Self and proxy (parents and teachers’) reports of child motor competence: A three-year longitudinal study

ObjectiveThe aims of this study were to: 1) analyse the longitudinal trends in the evolution of the association between children’s actual and perceived motor competence (AMC and PMC, respectively) according to the source of information: children, parents, and Physical Education (PE) teachers; 2) assess whether children, parents, and PE teachers can report on children’s AMC longitudinally (considering the children’s age, sex, and the type of motor competence).Design and methodA sample of 108 typically developing Spanish children (47.12% girls) from five schools participated in this study. AMC and PMC (locomotion, object control and overall MC) data was collected at three time points one year apart. Longitudinal mixed effects models with repeated measures were conducted.ResultsRegardless of the domain of MC, no longitudinal association between children’s AMC and PMC was found. Parents also exhibited limited capability to proxy report their children’s AMC longitudinally. PE teachers’ proxy reports of children’ AMC were associated over time with object control and overall level.ConclusionThis study confirms the necessity of specific training in AMC to effectively report on children’s motor competence. PE teachers can be seen as a potential source to empower children’s AMC and PMC development over time.     

The role of motivation in the conceptual model of motor development in childhood

The aim of this study was twofold: first, to investigate whether perceived motor competence (PMC) mediates the relation between actual motor competence (AMC) and physical activity (PA) according to the conceptual model of motor development, and second to examine the role of different motivational regulations (i.e., intrinsic, identified, introjected, and external regulation) in the relationship between PMC and PA. A sample of 504 Spanish students (46.2% girls, 8–12 years old) voluntarily participated in this study. In relation to the first aim, structural equation modeling revealed that PMC indeed mediates the association between AMC and PA. In relation to the second aim, positive associations between AMC and PMC (β = 0.32, p < .001), which in turn was positively related to intrinsic and identified regulations (β = 0.46 and β = 0.43 respectively, p < .001), were found. The model showed direct paths from intrinsic and introjected regulation to PA (β = 0.27 and β = 0.22, p < .05) and indirect paths from PMC through intrinsic motivation to PA (β = 0.13, p < .05). This study confirms that intrinsic motivation mediates the association between PMC and PA. Strategies targeting to build and develop children’s AMC and PMC, and fostering children’s intrinsic motivation should be targeted to promote children’s PA engagement and motor development.     

Quiet eye training improves throw and catch performance in children

ObjectivesTo compare quiet eye training (QET) and ‘traditional’ technical training (TT) interventions for a throw and catch task in children.DesignThis pilot study adopted a between groups randomized control design.MethodSixteen, 10 year-old typically developing children performed 10 pre- and 10 post-test trials before and after QET or TT, while wearing a Mobile Eye gaze registration system. Both interventions consisted of three video demonstrations (focusing on the throw, the catch, and linking the throw and catch) followed by a series of practice trials. QET videos emphasized gaze strategy instructions whereas TT videos emphasized traditional primary school throwing and catching instructions.ResultsSignificant interaction effects for performance and quiet eye durations revealed that only the QET group significantly lengthened QE durations, which contributed to significant improvements in catching from pre- to post-test.ConclusionsQET may be an effective method for improving throwing and catching skills in typically developing children.     

Plotinus: towards an ontology of likeness (On the One and Nous)

Plotinus’ thesis of the relationship between the One and Nous (Intellect) is central to his thought. In dealing with this relationship, he concentrates far more on what makes the One and Nous alike than on what makes them different. This is because by preference he envisages the One as the ‘causal principle () of everything’, in what might be termed a ‘top‐down’ model of metaphysics in which first cause (the One) leads downwards to second cause (Nous). Plotinus is obliged to present the distinction between the One and Nous as relative, not as absolute, precisely because he wants to show that Nous is firmly grounded in the One. The One differs from Nous to no more than the degree, and in no more than the manner, that are necessary for there to be created a Nous which is as like as possible to the One Itself.     

ISLAMIC PHILOSOPHY AND THE CHALLENGE OF CLONING

Scientific achievements, especially in contemporary biology, have led and continue to lead to uncertainties for some believers with regard to their understanding of the role of God as the creator. This essay, avoiding philosophical jargon, expounds the stance of Islamic philosophy on this matter and argues that such anxiety and doubt are unfounded. Drawing upon the thousand‐year‐old distinction between two types of cause, real and preparatory, as formulated by Muslim philosophers, the argument demonstrates that seeing biological advances as rivaling God's creation, as traditionally understood in the Abrahamic religions, is a premature judgment based on a faulty conflation. This comes to light most clearly through Mulla Sadra's analysis of causality, the far‐reaching implications of which are briefly mentioned.     

遵从行为的调查研究

本研究根据遵从行为反映沦的观点,通过对576名在校大学研究生和本科生“关于对‘非典’时期学校实行‘封闭管理’规定的态度”的问卷调查。结果表明：(1)遵从行为在积极的行为目的、行为归因、意志过程和情绪体验四个方面具有内在的一致性;(2)服从行为在消极的行为目的、行为归因、意志过程和情绪体验四个方面具有内在的一致性;(3)遵从行为和服从行为在意志过程和情绪体验反应的程度上受归因倾向的影响;(4)顺从行为只足在归因倾向和情绪体验方面表现出消极的倾向性特点,意志过程特点反映不确定。     

Circumstances of Death and Complicated Grief: Indirect Associations Through Meaning Made of Loss

Losses by violent means and the loss of primary attachment figures may increase the likelihood of developing a chronic and severe grief response (referred to as complicated grief, or CG). Path analysis was used to examine the relationships between these risk factors and CG symptoms. College student participants filled out online questionnaires relating to their bereavement. Analyses provided support for statistical models whereby meaning made of the loss fully mediated the association between cause of death and CG symptoms and partially mediated the association between relationship to the deceased and CG symptoms. Although based on cross-sectional data, these findings provide additional support for meaning-oriented understandings of adaptation to loss.

Mindfulness reduces the correspondence bias

The correspondence bias (CB) refers to the idea that people sometimes give undue weight to dispositional rather than situational factors when explaining behaviours and attitudes. Three experiments examined whether mindfulness, a non-judgmental focus on the present moment, could reduce the CB. Participants engaged in a brief mindfulness exercise (the raisin task), a control task, or an attention to detail task before completing a typical CB measure involving an attitude-attribution paradigm. The results indicated that participants in the mindfulness condition experienced a significant reduction in the CB compared to participants in the control or attention to detail conditions. These results suggest that mindfulness training can play a unique role in reducing social biases related to person perception.
