An experiment on Prisoner’s Dilemma with confirmed proposals

We suggest an alternating proposals protocol with a confirmation stage as a way of solving a Prisoner’s Dilemma game. We interpret players’ proposals and (no) confirmation of outcomes of the game as a tacit communication device. The protocol leads to unprecedented high levels of cooperation in the laboratory. Assigning the power of confirmation to one of the two players alone, rather than alternating the role of a leader significantly increases the probability of cooperation in the first bargaining period. We interpret pre-agreement strategies as tacit messages on players’ willingness to cooperate and as signals pursuing individualistic objectives like publicizing one’s bargaining abilities or eliciting those of the opponent.     

Who Rules the Ruler? On the Misconduct of Journal Editors

There are very few (published) accounts of editorial misconduct, and those that do exist are almost exclusively focused on medicine-related areas. In the present article we detail a case of editorial misconduct in a rather underexplored domain, the social sciences. This case demonstrates that although legal systems provide different instruments of protection to avoid, compensate for, and punish misconduct on the part of journal editors, the social and economic power unbalance between authors and publishers suggests the importance of alternative solutions before or instead of bringing a lawsuit to court. It puts forward strong arguments in favour of the need for effective regulatory bodies so as to achieve and maintain a culture of research integrity by all involved in the process.     

Development of "hot" executive function: the children's gambling task

Development of affective decision-making was studied in 48 children at two ages (3 and 4 years) using a simplified version of the Iowa Gambling Task (). On each of 50 trials, children chose from 1 of 2 decks of cards that, when turned, displayed happy and sad faces, corresponding to rewards (candies) won and lost, respectively. Cards in 1 deck offered more rewards per trial, but were disadvantageous across trials due to occasional large losses; cards in the other deck offered fewer rewards per trial, but were advantageous overall. On later trials, 4-year-olds made more advantageous choices than 3-year-olds, and 4-year-olds made more advantageous choices than would be expected by chance, whereas 3-year-olds made more disadvantageous choices than would be expected by chance. These findings, which were especially pronounced for girls, indicate that affective decision-making develops rapidly during the preschool period, possibly reflecting the growth of neural systems involving orbitofrontal cortex.     

A Meta-Analysis on the Efficacy of Technology Mediated CBT for Anxious Children and Adolescents

Several meta-analyses indicate that cognitive-behavioral therapy (CBT) via electronic/technological devices or applications (i.e., eCBT) is an effective alternative to standard therapist-delivered CBT for anxious adults. However, we know little about the efficacy of eCBT interventions for anxious children and adolescents. The present meta-analysis set out to investigate the efficacy of eCBT in comparison to standard CBT or waitlist control for anxious children and adolescents. Eight randomized controlled studies (N = 404 participants) that targeted anxiety at post-intervention and follow-up were included in the analysis. The results indicated that eCBT was as effective as standard CBT (g = .295) and more effective than waitlist (g = 1.410) in reducing anxiety symptoms. Moderation analyses revealed that anxious children and adolescents benefited the most from eCBT in the minimal therapist involvement condition (g = 2.682) in contrast to the significant therapist involvement group (g = .326). Furthermore, older participants seemed to extract greater clinical benefits from eCBT in contrast to younger participants (slope = .514). Current eCBT interventions for anxious children and adolescents appear to be promising, but require further investigation.     

Unpacking Social Avoidance and Substance Use in Social Anxiety: Does Extraversion Explain Behavior Variability?

Social anxiety is characterized by heightened fear and anxiety associated with social situations, resulting in the use of avoidance behaviors. Contemporary models suggest that some individuals with social anxiety may choose to completely avoid social situations, while others may seek social connections and interactions and utilize avoidance behaviors such as substance use as a means of distress tolerance, while engaging in these situations. Our aim is to test a theoretical model whereby extraversion could help to explain the heterogenous nature of social anxiety in relation to these behaviors. Lower levels of extraversion have been commonly associated with withdrawal behaviors and higher levels of extraversion have been associated with behaviors commonly enacted in social situations. Understanding factors which predict the use of one behavior over another is imperative to the conceptualization and successful treatment of patients with social anxiety. A sample of 195 college students completed self-report measures and a 10-day experience sampling diary with five diary signals each day. Participants were asked to rate their current negative emotions and behaviors during each diary signal. Using a multilevel modeling approach, we tested the association between social anxiety symptoms and negative affect predicting engagement in substance use or social avoidance and tested whether extraversion moderated this association. Negative affect was included as a covariate given the established associations between elevations in negative affect predicting both behaviors. Results indicated that higher levels of social anxiety symptoms and negative affectivity increased the probability of social avoidance and substance use, and extraversion was a significant predictor for only substance use. Moderation analysis indicated that extraversion moderated the relationship between social anxiety and substance use, suggesting a stronger positive relationship between substance use and social anxiety for individuals higher in extraversion. However, extraversion was not a significant moderator between social anxiety and social avoidance. Overall, the findings suggest that extraversion could be a key factor predicting the use of substances amongst individuals with social anxiety and may need further consideration in treatment.

     

Valor terapéutico de las técnicas de terapia de conducta: una hipótesis de trabajo

Resumen

La literatura científica y la propia experiencia clínica nos muestra que las tánicas terapéuticas d la terapia d conducta son bastante eficaces. Sin embargo, esta eficacia no es cercana al 100%. ¿Por qué? Por otra parte, se puede constatar que una misma técnica es eficaz muchas veces en el tratamiento de diferentes trastornos, y al contrario, varias técnicas, diferentes entre sí, se revelan óptimas para el tratamiento del mismo trastorno. Sin embargo, todo ello no es constante a lo largo de diferentes casos. Este trabajo pretende reflexionar sobre todos estos aspectos y ofrecer algunas explicaciones del por qué de este estado de la cuestión. Posibles vías de investigación se sugieren a lo largo del artículo.     

Lessons In The Psychology Of Loss: Accounts Of Middle-Aged Romanian Women

Abstract

In studying loss, it is important to develop a cross-cultural, interdisciplinary approach that is concerned with the historical, cultural, and social contexts in which loss occurs. However, the Western field of psychology is less well informed about the experiences and perspectives of loss across various cultures. Many countries in the contemporary world are seeking greater participation in the international community and control over their destinies. The related cultural, political, and social developments are commanding a need for heightened awareness and understanding of ethnic variations in dealing with the social change phenomenon and the psychology of loss.     

Effects of emotion regulation strategies on smoking craving, attentional bias, and task persistence

The goal of this study was to investigate the effects of different strategies for regulating emotions associated with smoking on subjective, cognitive, and behavioral correlates of smoking. Emotion regulation was manipulated by instructing participants to reappraise (n = 32), accept (n = 31), or suppress (n = 31) their emotions associated with smoking. The dependent measures included subjective reports of craving, negative affect, and attentional biases, as measured by a modified dot-probe task, and persistence during a task to measure distress tolerance. Individuals who were encouraged to reappraise the consequences of smoking showed diminished craving, lower negative affect, had reduced attentional biases for smoking-related cues, and exhibited greater task persistence than those who were instructed to accept and suppress their urge to smoke. These findings suggest that reappraisal techniques are more effective than acceptance or suppression strategies for targeting smoking-related problems.     

Psychological and Social Characteristics Associated with Religiosity in Women’s Health Initiative Participants

Measures of religiosity are linked to health outcomes, possibly indicating mediating effects of associated psychological and social factors. We examined cross-sectional data from 92,539 postmenopausal participants of the Women’s Health Initiative Observational Study who responded to questions on religious service attendance, psychological characteristics, and social support domains. We present odds ratios from multiple logistic regressions controlling for covariates. Women attending services weekly during the past month, compared with those not attending at all in the past month, were less likely to be depressed [OR = 0.78; CI = 0.74–0.83] or characterized by cynical hostility [OR = 0.94; CI = 0.90–0.98], and more likely to be optimistic [OR = 1.22; CI = 1.17–1.26]. They were also more likely to report overall positive social support [OR = 1.28; CI = 1.24–1.33], as well as social support of four subtypes (emotional/informational support, affection support, tangible support, and positive social interaction), and were less likely to report social strain [OR = 0.91; CI = 0.88–0.94]. However, those attending more or less than weekly were not less likely to be characterized by cynical hostility, nor were they less likely to report social strain, compared to those not attending during the past month.     

Do sequence-space synaesthetes have better spatial imagery skills? Maybe not

Sequence-space synaesthesia is a type of visuo-spatial imagery in which numbers or calendar units are experienced to occupy locations in space. Previous studies have claimed that these synaesthetes (1) have stronger self-reported visual (but not spatial) imagery and (2) perform unusually well on mental rotation tasks that are usually taken to reflect spatial (but not visual) imagery. To further investigate whether this form of synaesthesia is related to spatial imagery, we compared synaesthetes to controls on the Object Spatial Imagery Questionnaire, a paper folding test and a mental rotation task. The synaesthetes did not differ from controls in self-reported spatial imagery, but showed a strong trend to report better visual imagery, replicating previously reported data patterns. Consistent with this, their paper folding and mental rotation performance was no better than controls. We also confirmed that, in our pooled sample, performance on both these tasks was positively correlated with self-reported spatial imagery. We suggest our data are more consistent with the view that sequence-space synaesthesia is related to visual than to spatial imagery, and we suggest reasons why previous studies may have found superior mental rotation performance.
