Attentional bias for doping words and its relation with physical self-esteem in young adolescents

ObjectivesPrevious studies revealed that adolescence is a period of risk for doping and drug addiction and that young athletes who used doping agents reported low self-esteem. We conducted a preventive study with the aims to investigate whether young adolescents displayed an attentional bias to doping-related words and whether this attentional bias was related to physical self-esteem.MethodNinety seven adolescents (44 girls and 53 boys) from 11 to 15 years-old participated to a study designed to measure reaction times (RT) in a Stroop emotional task related to doping, cheating and control words. They also completed the Physical Self-Perception Profile subscales assessing perceived general self-esteem, physical self-worth, physical condition, sport competence, body attractiveness, and physical strength.ResultsParticipants exhibited longer RT after doping words than after control words. RT was also longer after doping than after cheating words. Participants belonging to the low physical self-esteem group exhibited larger carry-over effects than those who were in the high physical self-esteem group.ConclusionsThese findings suggest that attentional resources allocated to doping words are already present at the onset of adolescence, and that they may be linked to a psychological feature (physical self-esteem) considered as a risk factor of substance abuse in young adults involved in competitive sports.     

Part-set cuing in option generation

Memory research on the part-set cuing effect has shown that providing some of the to-be-remembered items as cues is not always beneficial and, in some cases, may even hurt retrieval. However, part-set cuing has been sparsely investigated in option generation tasks. Thus, limited empirical evidence for the existence of the effect in option generation is available, and no convincing explanation has been provided yet. In order to fill these gaps, we carried out four experiments. In Experiment 1A, we observed a significant decrease in option generation performance when potential options were presented as cues. Experiment 1B showed that the effect can also be obtained in older adults. Experiments 2A and 2B provided evidence compatible with an inhibition-based explanation of the observed effects.     

Relapse of operant behavior after response elimination with an extinction or an omission contingency

The present study compared relapse after responding was eliminated by extinction or omission training in rats. In Experiment 1, lever pressing was reinforced with food pellets in Context A and then eliminated with either extinction or omission training in Context B. The response was then tested in Contexts A and B in either the presence or absence of free food pellets delivered on a random time schedule. All rats showed higher responding when tested in Context A than Context B, and there was little evidence that omission training attenuated this ABA renewal effect. Noncontingent pellets increased responding after extinction but not after omission. However, when responding on the last day of response elimination was compared to responding during the test in the response-elimination context, there was some evidence that omission-trained rats showed a small increase in responding even when tested with free pellets. Results of Experiment 2 suggest this increase was not due to differences in the temporal distribution of pellets during elimination and the test, and that the result might be due to mere removal of the omission contingency, but any such effect is small and difficult to detect statistically. The results provide new information about factors generating relapse after omission training.     

Mental Health Professionals' Perceptions of Women's Experiences of Family Violence

This study explored perceptions of 92 mental health professionals regarding violent families. They were asked to answer the questions on the Family Environment Scale as they thought women who lived in homes where they and their children were physically and/or psychologically abused would respond. Their scores were compared to those of 28 mothers in battered women's shelters. They differed significantly in their perceptions of violent family dynamics with regard to levels of cohesion, expressiveness, independence, intellectual-cultural orientation, active-recreational emphasis, and moral-religious emphasis. They believed the women to have lower levels on these constructs than the women actually reported. Implications suggest that mental health professionals could be more aware of the dynamics of violent families in order to efficiently uncover the violence during therapy sessions and provide appropriate services.     

Baudelaire’s Aesthetic

This paper will take up the work of Charles Baudelaire, poetic and critical, in order to present the Baudelairean aesthetic and to make a case for its relevance in our judgments about art today. Baudelaire was the first poet of the modern built environment and is known as the father of modern poetry. While his poetry is still admired, his aesthetic has been historicised: deemed to belong to that time and place in which Baudelaire wrote. This paper will argue that this historicisation by subsequent aesthetic theory and philosophy is a suppression of something integral to art and artists, without which art is liable to lose what is true about it and sink into a morass of irrelevance and triviality, or (as will be argued has partly happened) may become devoid of any value beyond the business interests that control it. In this regard, it will be suggested, Baudelaire’s aesthetic has important redeeming qualities.     

宗教资本:从布迪厄到斯达克

"宗教资本"概念对理性选择理论的发展至关重要,然而,"宗教资本"的诸多定义却常常模糊不清,或脱离于其所源出的知识构架。关于"宗教资本"概念,有两种相互独立发展的理论:其一大致属于欧洲,源自韦伯和布迪厄的研究;其二大致属于美国,源自艾纳孔和斯达克的研究。泰瑞·雷对通过对两种理论的比较研究,进而厘清其理论谱系,仔细考察了宗教资本概念及其衍生概念"灵性资本"的应用和批评,并提出了两个具有独创性的修正概念("制度宗教资本"和"民间宗教资本"),以此解决宗教资本概念在学术著作和文章中所出现的问题。     

Efficacy and feeling of a vibrotactile Frontal Collision Warning implemented in a haptic pedal

A haptic pedal has been designed to emulate the behaviour of a common vehicle pedal and render superimposed vibrations with different characteristics. It was installed in a driving simulator, as an accelerator pedal with the secondary function of a vibrotactile Frontal Collision Warning (FCW). The efficacy and feeling of this solution was tested with 30 subjects using vibrotactile signals with 0.50, 1.05, and 1.60 Nm, at 2.5, 5, and 10 Hz, against a baseline visual FCW. Participants had to match the speed of a leading vehicle when the FCW was triggered. Their braking response was evaluated in terms of brake reaction time, matching speed time, control of velocity and headway reduction. Driver’s feelings were assessed with Kansei methodologies. Haptic stimuli were found to be more effective than visual signals, and the characteristics of the vibration also influenced the results. The best performance was achieved at the maximum amplitude, and in the range between 5 and 10 Hz. The perceived functionality and discomfort followed a trend coherent with the objective measurements. The conclusions of this study may be applied to develop effective and safe warning systems in vehicles, limiting the annoyance that they might cause to drivers.     

Bidirectional influences in mother–toddler dyads: an examination of the relative influence of mothers' and children's behaviours

This study examined bidirectional relationship between mothers' lax and overreactive discipline and children's misbehaviour and negative effect. We examined the moment‐to‐moment stability of mothers' and children's behaviours (actor effects) and mothers' and children's influence on their partners' subsequent behaviours (partner effects). Participants were 71 mothers and their 24‐ to 48‐month‐old children observed during a 30‐min interaction. Both children and mothers exhibited stability in their own behaviours and influenced the subsequent behaviours of their partners. Additionally, a comparison of partner effects indicated that overreactive discipline more strongly predicted child's negative effect than child's negative effect predicted overreactive discipline. In contrast, although a child's negative effect predicted lax discipline, lax discipline did not predict subsequent child's negative effect. Copyright © 2010 John Wiley & Sons, Ltd.
