More than words: Rethinking sustainability communications through neuroscientific methods

In the era when the overarching problem of climate change, threatening the entire humanity and all life on earth, demands actions and behavioural change from all of the societal agents, including governments, organizations, companies and individuals, the world fails to achieve unity on the matter of existence of the problem, cause of the problem and on the solution of the problem. Since the scientific consensus on climate change is achieved, this article tries to examine why it is so hard to convey the message of needed behavioural change. The neuromarketing study presented in this article focuses on marketing communications that try to convey the message that would lead to the consumers' mental, emotional and behavioural change. Effectiveness of the branded environmental videos was evaluated utilizing the neuroscience approach. Electroencephalogram and an eye-tracking device were used to register the implicit brain reactions of the study participants viewing the branded videos. For comparison reasons, the branded videos selected for the study use two different approaches for conveying the message. The first approach relies on narrative, words and logic, whilst the second one appeals primarily to emotions. The aim of the study was to answer the question whether the words are enough or is there more to it?     

Self-reported versus measured weight and height by adolescent girls: a Croatian sample

Self-reported and measured weight and height of 234 Croatian girls in Grades 5, 8, and 11 were used to explore the validity of these measures for calculating Body Mass Index. For both weight and height, the correlations between self-reported and measured values were over .93. Overweight girls underreported their weight and overreported their height.     

Does stimulant medication decrease the lower extremity response times of children with and without attention-deficit/hyperactivity disorder?

In 2005 Pedersen and Surburg reported that stimulant medications reduced the lower extremity response times of 16 boys with Attention-Deficit/Hyperactivity Disorder. However, as boys without ADHD and girls with and without ADHD were not studied, one cannot conclude that reported effects represent a medication effect unique to children with ADHD. An alternative hypothesis is presented: that stimulant medications produce an excitatory effect in the central nervous system by increased occupancy of postsynaptic dopamine receptors to reduce the lower extremity response times of children in general. Well-designed controlled clinical trials are needed to evaluate this hypothesis.     

Gender Differences in Virtual Negotiation: Theory and Research

Social roles create conflicting behavioral expectations for female negotiators; however, virtual negotiations reduce social pressures. This paper reviews theoretical explanations on why men and women might differ in negotiations that occur through email, telephone, or video. Forty-three negotiation studies comparing face-to-face and virtual negotiations were examined for gender differences. All studies were reported in English but not limited to US participants. While many reports omitted gender information, meta-analytic findings supported the prediction that women would be more hostile in virtual compared to face-to-face negotiations, as well as finding no hostility difference for men between virtual and face-to-face negotiations. While negotiators overall were more successful face-to-face than virtually, results separated by gender did not find this effect.     

The good,the bad (and the ugly): The role of curiosity in subjective well‐being and risky behaviors among adolescents

Previous studies have shown that enhanced trait curiosity has positive influence on well‐being. It remains an open question, however, whether curiosity has any detrimental effects on behavioral outcomes in adolescence. The main aim of this research was to investigate the role of trait curiosity in the prediction of risky behavior engagement and subjective well‐being (SWB) among adolescents. A total of 371 Serbian adolescents (mean age 15.5, SD = 0.57) participated in the 5‐month follow up study. The results showed that the embracing component of curiosity (but not stretching) predicted risky behavior engagement, while the stretching component of curiosity (but not embracing) predicted positive affect. In addition, neither embracing nor stretching was a significant predictor of negative affect and life satisfaction. The results of this study call into question the conceptualization of curiosity as a completely positive emotional‐motivational system, and suggest that curiosity can contribute to negative outcomes in adolescence.     

When Less is More: A Short Version of the Personal Optimism Scale and the Self-Efficacy Optimism Scale

The past few years have seen increased theoretical and applied research on the relations between constructs related to positive expectations. However, instruments capable of distinguishing positive expectancy constructs are still lacking. This study evaluated the psychometric properties of the 18-item Personal Optimism Scale and Self-Efficacy Optimism Scale. Two student samples from the University of Novi Sad in Serbia were recruited for the present research, with a total of 728 participants. The results of the exploratory and confirmatory factor analyses did not support the theoretically expected structure. The results of the confirmatory factor analysis and content validity support shortening the scale to 9 items. The short versions of the scales demonstrated adequate reliability in internal consistency and adequate concurrent and convergent validity by significant correlations with dispositional optimism, general self-efficacy, hope, resilience and subjective well-being. The analyses lead us to conclude that a shorter 4-item Personal Optimism Scale and a 5-item Self-Efficacy Optimism Scale provide a clear, precise measures of two types of positive expectations. The authors argue that the limitations of the original scales emanate from their vague theoretical-substantive validity, and call for future research to replicate these findings.     

Proactive Coping as a Mediator Between Resources and Outcomes: A Structural Equations Modeling Analysis

Proactive coping is a recent construct in the field of positive psychology. It refers to the efforts aimed at building general forces to facilitate the path toward challenging goals and personal growth. The current study adopted a theoretical model of proactive coping as a mediator of resources with positive and negative outcomes. Our aim was to examine two separate models with satisfaction with life and depression as the proposed outcomes of proactive coping. The proposed models presumed direct relationships between self-efficacy, optimism and social support with life satisfaction or depression, as well as indirect paths through proactive coping. We administered a set of questionnaires that consisted of demographic data, the Proactive Coping Scale, the General Self-efficacy Scale, the Life Orientation Test-Revised, the Perceived Social Support Scale, the Beck Depression Inventory, and the Satisfaction with Life Scale. Data were obtained from a sample of high school graduates (N?=?485, age 17 to 19, 174 males and 311 females). Our analyses confirmed presumed direct and indirect relationships between resources and outcomes. The results showed that the data fit well in the model with life satisfaction as an outcome, while the data did not fit well in the model with depression as an outcome. A subsequent model was formed in which satisfaction with life was used as a full mediator between proactive coping and depression; this model provided a good fit to the data. Theoretical implications, as well as suggestions for future research, are discussed.
