Assessing potential reinforcement-like effects of brief stimuli unrelated to food reinforcers

It is widely assumed that reinforcers are biologically relevant stimuli, or stimuli that have been associated with biologically relevant stimuli. However, brief, arbitrary stimuli have also been reported to have reinforcement-like effects, despite being unrelated to biologically relevant stimuli like food. The present study explored the potential reinforcement-like effects of brief stimuli across 5 experiments. In Experiments 1 through 4, pigeon subjects responded for food reinforcement and brief stimulus presentations in a 2-component multiple schedule. Neither baseline response rates nor resistance to change during disruption tests were systematically greater in a component with versus without brief stimulus presentations. Increasing the rate and duration of brief stimulus presentations in Experiment 4 did not reveal reinforcement-like effects when compared directly with food. In Experiment 5, pigeons chose between independent terminal links in a concurrent-chains procedure. Across conditions, varying the location, duration, and rate of brief stimulus presentations in the terminal links had no systematic effects on preference. In contrast, varying rates of food reinforcers resulted in large and reliable shifts in preference. Therefore, the present study found no systematic evidence that brief stimuli unrelated to food reliably increase response rates, resistance to change, or preference. These data demonstrate the value of systematic replication, and a behavioral momentum approach to assessing potential reinforcement-like effects.     

The dark side of emotional intelligence: the role of gender and the Dark Triad in emotional manipulation at work

Objective : This study investigated people's willingness to emotionally manipulate others maliciously and disingenuously in the workplace. It also examined the role of gender, emotional intelligence, and the Dark Triad traits in this destructive behaviour. Method : A sample of employees (N = 765; 581 females, 184 males) from varying occupations completed measurements of emotional manipulation willingness in the workplace, emotional intelligence, and the Dark Triad. Results : T-tests revealed that females were significantly less likely than males to engage in both malicious and disingenuous emotional manipulation. In bivariate correlations, higher levels of emotional intelligence were associated with disingenuous emotional manipulation in females only. Emotional intelligence was also a significant contributor to disingenuous emotional manipulation in multiple regression analysis, indicating the existence of a “dark side to emotional intelligence” at work. In females, the magnitude of correlations (small to moderate) between the Dark Triad traits and both forms of emotional manipulation were similar. In males, both forms of emotional manipulation most strongly correlated with Machiavellianism, followed by narcissism, then psychopathy. Conclusion : This study is the first to demonstrate that good emotional intelligence skills can facilitate undesirable workplace behaviours. Emotional manipulation is elevated in males with a relentless drive to achieve goals, and in females with broader deceptive tendencies.     

Early pathways to bullying: A prospective longitudinal study examining the influences of theory of mind and social preference on bullying behaviour during the first 3 years of school

Research has focused on the role of theory of mind (ToM) for positive social behaviour, while the association between ToM and negative social behaviours is less well understood. This longitudinal study compares two mediation models examining the role of ToM and peer-rated social preference at ages 5 and 6 for bullying at age 7. Participants were 114 children (58 boys, M_age = 67 months) at entry to primary school (T1). At Time 2 (T2), 106 children and, at Time 3 (T3), 96 children remained. Teacher-rated externalizing problems and children’s language ability were controlled at T1. Poor ToM was found to indirectly predict later bullying via poor social preference, while for boys only, greater earlier ToM directly predicted greater bullying 2 years later. These results suggest that there are different pathways to bullying via ToM and social preference , which has implications for interventions to prevent the development of bullying behaviour.     

The decision to check in multialternative choices and limited sensitivity to default

Given the rapid proliferation of smartphone applications and data aggregation websites, in many situations people can use decision aids to guide their choices. For example, they may consider whether to use a navigation device to check the fastest route or whether to use a price comparison website to find the cheapest deal. In what circumstances will subjects use a costly comparison decision aid (which I refer to as “checking”) to choose for them? In six studies, I investigate the impact of the number of available alternatives and checking's attractiveness on the decision to check. While at first increasing the attractiveness of checking led to higher checking rates, a further increase in the number of available alternatives (and thus checking's attractiveness) did not increase the checking rate. Surprisingly, even when checking had a 40% higher expected value compared with not checking, the observed checking rate was below 45%, contrary to risk and ambiguity aversion predictions. Furthermore, labeling the checking alternative as the default had no impact on its choice rate. I find large individual differences in decisions to check. Surprisingly, subjects' initial decisions had high predictive power over their subsequent checking rates, even after 100 trials with full feedback. I propose two simple learning models that capture well the aggregated results.     

A Dance with Many Secrets: The Experience of Emotional Harm from the Perspective of Past Professional Female Ballet Dancers in Canada

Originating in the Italian and French courts, ballet is an age-old art that fuses aesthetics and athleticism (Wulff, 2008). Despite changing times, ballet masters and mistresses tenaciously hold on to a sense of deep traditionalism. However, some scholars suggest that unwavering devotion to the art may conceal troubled embodied relations and oppressive practices (Gvion, 2008). In this study, we drew on the phenomenological research tradition in an effort to further examine the power relations that play out on the body in the world of Canadian professional ballet (Papaefstathiou, Rhind, & Brakenridge, 2013). Twenty past professional female ballet dancers from across Canada participated in this study. Our dedicated dancers were relentless. They sacrificed body and mind in the pursuit of excellence in a broader cultural context that expected nothing less. The dancers normalized harmful emotional experiences, inappropriate sexual transgressions, and chronic injury (Gvion, 2008). They also described experiences of neglect—and feeling replaceable—after the onset of injury. We have attempted to theorize our findings within the context of embodiment literature and the work of gender theorists. Emboldened by our dancers’ voices, we have shed light—and broken secrets—regarding some of the harmful practices that still characterize professional ballet in Canada. We hope that our work might further continue efforts to democratize power imbalances in professional ballet and ultimately enhance holistic dancer development and health.     

Dispositional Mindfulness,Posttraumatic Stress Disorder Symptoms and Academic Burnout in Chinese Adolescents Following a Tornado: The Role of Mediation through Regulatory Emotional Self-Efficacy

Limited research has been conducted on dispositional mindfulness, posttraumatic stress disorder (PTSD) symptoms and academic burnout in Chinese adolescents following a tornado. The present study investigated the ways in which dispositional mindfulness is related to PTSD symptoms and academic burnout in Chinese adolescents following a tornado by considering the role of regulatory emotional self-efficacy. A total of 431 Chinese adolescents (mean age: 14.75 years) who had experienced a severe tornado 9 months prior to this study were recruited for this study. The results indicated that our model fit the data well [χ²/df = 2.774, CFI = 0.952, TLI = 0.934, RMSEA (90% CI) = 0.064 (0.051–0.077)], and revealed that regulatory emotional self-efficacy partially mediates the relationships between dispositional mindfulness and PTSD symptoms and academic burnout, respectively. The clinical implications and limitations of our research, and recommendations for future research, are discussed in this paper.     

Aggression in Children With Reactive Attachment Disorder: A Sign of Deficits in Emotional Regulatory Processes?

Children diagnosed with reactive attachment disorder (RAD) have been reported to exhibit a multitude of symptoms and behaviors that are not captured by the Diagnostic and Statistical Manual of Mental Disorders criteria. One behavior in particular that has been the source of much argument and controversy is aggression. Although limited research on this topic does support an association between aggression and RAD behaviors, the exact nature of this link remains unclear. This study aims to fill this gap by reporting data from a study that examined the behavioral processes that occur in adopted children with RAD. Guided by the principles of grounded theory, this study employed a multi-stage semi-structured interview design. The sample consisted of 5 adoptive families, and included both adult and child participants, including the adopted children with RAD. The findings revealed 5 prominent themes: The adopted children are reported to engage in extreme and prolonged tantrums, known as rages; children were often inconsolable during these rages; these rages are perceived as uncontrollable by children with RAD; these rages are directed toward a discriminate caregiver; and the impetus for these rages appears to be associated with difficulties in adapting to environmental demands. An in-depth discussion that draws a theoretical connection between these rages and possible deficits in brain-based processes responsible for emotional regulation is presented.
