Just banter? Friendship,teasing and experimental aggression in adolescent peer networks

Aggressive behaviour serves many useful social functions, yet can also have damaging consequences. In line with evidence showing adolescent development in social cognitive abilities, we hypothesized that the use of aggression would become more sophisticated with age. We investigated adolescent aggression towards peers using an experimental, hypothetical aggression paradigm, the hot sauce paradigm, in a school‐based social network setting. Participants (N = 162 aged 11–17, 98 male) indicated which strength of imaginary hot sauce they would allocate to each of their classmates. A Social Network Questionnaire quantified participants’ perceived dyadic social tie strength with each classmate, and the incidence of mutual or unilateral dyadic real‐world aggression (e.g. teasing). Participants allocated weaker hot sauce to peers with whom they reported strong, positive social ties and an absence of self‐reported unilateral real‐world aggression. With increasing cross‐sectional age, there was a decrease in the impact of social tie strength and an increase in the extent to which hot sauce allocation was predicted by self‐reported mutual real‐world aggression. This pattern of findings is consistent with young (vs. late) adolescent use of experimental, hypothetical Hot Sauce aggression to reflect real‐world animosity, while late adolescents’ behaviour is more subtle. These findings extend our understanding of the dyadic social context of adolescent aggressive behaviour using a novel experimental aggression paradigm.     

Possible influence of electrostatics in molecular bonding at supported metal nanoparticles

A mechanism is proposed for interaction between gas molecules and supported metal nanoparticles. Hot electrons that are formed via electron–hole pair excitations caused by exothermic reactions on the particles, enter into the insulating support, thereby leaving a positive charge that is distributed over the volume of the nanoparticle. The lifetime of the charge depends on the size of the metal particle and on the electronic and dielectric properties of the support, and may be too short for equilibrium to be established between the particle and its surroundings on the time scale of the chemical reaction. The electrostatic potential of the particle depends on its size, and therefore the position of the d-density of states of the particle, and thus the interaction with adsorbed molecules may be tuned by changing particle size. Thus, catalytic activity and selectivity may be affected for chemical reactions.     

Does child verbal ability mediate the relationship between maternal sensitivity and later self‐regulation? A longitudinal study from infancy to 4 years

There is a need to further examine the mechanisms by which maternal sensitivity influences the development of child self‐regulation. This study investigated the role of maternal sensitivity when infants were 10 months old and child verbal ability at 18 months, in relation to various aspects of self‐regulation at 48 months, in a sample of 95 typically developing children (46.3% girls). In particular, the study examined, from a Vygotskian perspective, whether child verbal ability, as measured by receptive and expressive language, mediated the relationship between maternal sensitivity and hot and cool aspects of self‐regulation in the child. As hypothesized, maternal sensitivity predicted child verbal ability, as well as working memory, set shifting, and delay of gratification. Child receptive language predicted set shifting, inhibition, and delay of gratification. In addition, receptive language mediated the relationship between maternal sensitivity and inhibition only. Additive effects of maternal sensitivity and child receptive language in relation to set shifting were found, and a main effect of maternal sensitivity on child delay of gratification. The results add to the body of research suggesting that responsive parenting and child verbal ability are important for the development of self‐regulation, and suggest that different mechanisms may be at work for different aspects of self‐regulation.     

Men’s experience of a guided self-help intervention for hot flushes associated with prostate cancer treatment

Up to 80% of men who receive androgen deprivation therapy report hot flushes and for many these are associated with reduced quality of life. However it is recognised that there are a number of barriers to men’s engagement with support to manage symptoms and improve quality of life. This qualitative study was embedded within a larger randomised controlled trial (MANCAN) of a guided self-help cognitive behavioural intervention to manage hot flushes resulting among men receiving androgen deprivation therapy. The study aimed to explore the engagement and experiences with the guided self-help intervention. Twenty men recruited from the treatment arm of the MANCAN trial participated in a semi-structured interview exploring acceptability of the intervention, factors affecting engagement and perceived usefulness of the intervention. Interviews were audio-recorded, transcribed verbatim and analysed using a Framework approach. Over two thirds of respondents (69%) reported reading the intervention booklet in full and over 90% reporting practising the relaxation CD at least once a week. Analysis of the interviews identified three super-ordinate themes and these related to changes in hot flush symptomatology (learned to cope with hot flushes in new ways), the skills that participants had derived from the intervention (promoting relaxation and reducing stressors), and to a broader usefulness of the intervention (broader impact of the intervention and skills). The present study identified positive engagement with a guided self-help intervention and that men applied the skills developed through the intervention to help them undertake general lifestyle changes. Psycho-educational interventions (e.g. cognitive behaviour therapy, relaxation, and positive lifestyle elements) offer the potential to be both effective and well received by male cancer survivors.     

The Automaticity of Affect for Political Leaders, Groups, and Issues: An Experimental Test of the Hot Cognition Hypothesis

We report the results of three experimental tests of the "hot cognition" hypothesis, which posits that all sociopolitical concepts that have been evaluated in the past are affectively charged and that this affective charge is automatically activated within milliseconds on mere exposure to the concept, appreciably faster than conscious appraisal of the object.
We find support for the automaticity of affect toward political leaders, groups, and issues; specifically:

• • 

  Most Ss show significantly faster reaction times to affectively congruent political concepts and significantly slower response times to affectively incongruent concepts;

       

人格智力:一种被“冷落”的“热智力”

人格智力(PI)是指个体在对人格及其相关信息推理的基础上,利用这些信息提高一个人的思想、计划和生活经验的能力,包括识别人格信息、形成人格模型、引导个人选择以及系统化计划和目标等相关领域。作为一种新兴的“热智力”,PI并没有像当年情绪智力(EI)那样受人关注。文章从PI的范畴、领域及其局限性等角度分析了这一新能力遭遇“冷落”的原因,指出了PI在整合以人为中心的智力过程中存在概念宽泛、界限模糊、测量的科学性及其形成与发展等诸多值得反思的问题。     

The Reinforcing Value of Lottery Tickets,and the Synergetic Effect of Distinct Reinforcements

We present two experiments that explore the reinforcing value of lottery tickets. Participants are faced with a repeated choice task between a safe alternative and a risky prospect that provides a chance to win a lottery ticket to be played at the end of the study. Study 1 considers situations in which the risky option leads to a slightly higher expected value than the safe alternative. It shows that the risk‐taking rate increases with the probability to win the lottery ticket, but it is below 50% even when this probability is high. Study 2 shows limited sensitivity to the expected value of the risky prospect. The results can be explained with the assumption that participants rely on small samples of past experiences, and that their reaction to lottery tickets reflects large variability. The relationship between the current results and previous research on the synergetic effect of distinct reinforcements and the “pat on the back paradox” is discussed.

Hot Sauce,toy guns,and graffiti: A critical account of current laboratory aggression paradigms

In 1996, Tedeschi and Quigley published a review of laboratory aggression research that included many damning criticisms of the genre. This paper revisits Tedeschi and Quigley's critique, and examines the ways that subsequent researchers have addressed the weaknesses they identified. In particular, it examines three new laboratory aggression paradigms (Hot Sauce, Bungled Procedure, and Experimental Graffiti Paradigms) that have attempted to improve upon the “classic” paradigms (Teacher/Learner & Essay Evaluation Paradigms, Competitive Reaction Time Game, Point Subtraction Aggression Paradigm, and Bobo Modelling Paradigm). In each case, this review will show, that although some aspects of the new designs are indeed improvements, many of Tedeschi and Quigley's arguments still apply. In conclusion, this investigation will identify a number of factors that future laboratory aggression researchers should consider. These include: The perceptions and motivations of the aggressor; the apparent distance between the aggressor and the target; the availability of non‐aggressive response options; the problems of demand characteristics, permissive cues and agentic shift; the differences between proactive and reactive aggression, and the distinction between overt and covert forms of aggression.

Evaluation and training of Executive Functions in genocide survivors. The case of Yazidi children

Executive Functions (EFs) development is critically affected by stress and trauma, as well as the socioeconomic context in which children grow up (Welsh, Nix, Blair, Bierman, & Nelson, 2010, Journal of Educational Psychology, 102 , 43–53). Research in this field is surprisingly lacking in relation to war contexts. This study represents a first attempt at addressing this topic by evaluating EFs in Yazidi children. The Yazidi community is an ethnic and religious minority living in Iraq. From August 2014 onwards, the Yazidi community has been the target of several atrocities perpetrated by ISIS and described as genocide by the international community at large. The University of Trieste, thanks to a program financed by the Friuli Venezia Giulia Region, developed a study aimed at (a) evaluating hot and cool EFs in children living in a war context and (b) developing a specific training method to enhance hot and cool EFs in Yazidi children of preschool age (N = 53). Data related to this group of children were compared with a sample of typically developing Italian children randomly assigned to either an EFs training group (N = 55) or a passive control group (N = 51). Results indicate different baselines in EFs in Yazidi and Italian samples and a significant effect of the program on both trained groups, especially in tasks measuring hot EFs. Data are discussed in terms of hot and cool EFs in children growing in adverse environments, as well as the evaluation of educational and developmental opportunities to prevent children who survived genocide from becoming a ‘lost generation’.
