Belief and Survival

Our ability to survive in a world beset by looming global perils depends ultimately on our collective will to harness our intellects and change our behaviors. In order to respond appropriately, people must first believe that serious problems exist, that there are potential solutions, and that they have a role to play in finding and implementing them. Without such beliefs, individual change is unlikely. In order to promote belief change, it is important to understand how beliefs are learned, what their functions are, and why they are so often resistant to change. These issues are discussed in this article, along with the role that social dilemmas play in inhibiting individually prosocial behavior.     

Influence of following vehicle’s tailway and classification on subject driver’s response to the circular yellow indication

Traffic crashes at signalized intersections are frequently linked to driver behavior at the onset of the circular yellow (CY) indication. To better understand behavioral factors that influence a driver’s decision to stop or go at an intersection, this study analyzed the behavior of the driver of a subject vehicle at the onset of the CY indication. Driver performance data from 53 participants were collected in the Oregon State University Driving Simulator, simulating scenarios of driving through high-speed intersections under various conditions. Data included interactions where the driver stopped at the stop line (n = 644) or proceeded through the intersection (n = 628) in response to a CY indication. Data were analyzed as panel data while considering 12 indicator variables related to the driver’s stop/go decision. These indicator variables included time to stop line (TTSL), tailway time, following vehicle type, vehicle speed at the onset of the CY indication, and demographics (age, gender, driving experience, level of education, personal vehicle type, number of times driving per week, number of miles driving last year, participation in previous simulation studies. A random-parameter binary logit model was used to determine contributing factors for driver decision making at the onset of CY indication while accounting for unobserved heterogeneity. Four indicator variables were significantly related to the driver’s stop/go decision, but three factors varied across observations. Findings showed that a driver’s stop/go decision in response to a CY indication was associated with the time to the stop line (TTSL), tailway time to the following vehicle, subject vehicle speed at the onset of the CY indication, and driver’s age (20–36 years), but was not significantly associated with classification of the following vehicle. Also, the findings indicated that a shorter tailway increased a subject driver’s red-light running frequency. These findings provide insights into variables that affect driver decisions in a vehicle-following situation at the onset of the CY indication. This information can help make better decisions in smart traffic control systems such as to extend/decrease the green interval slightly to avoid decisions that are more difficult.     

Behavioural Consistency Within the Prisoner's Dilemma Game: The Role of Personality and Situation

Mixed‐motive games represent situations that confront people with a conflict between cooperative and non‐cooperative alternatives. Despite this common basis, recent research has shown that the consistency of people's choices across different mixed‐motive games is rather low. The present research examined behavioural consistency within the same mixed‐motive game, by presenting participants with a series of one‐shot Prisoner's Dilemma Games. Across this set of games, payoffs were manipulated in order to intensify or weaken the conflict between self and the other party while maintaining the game's underlying structure. Our findings indicate that significant differences in choice behaviour are observed as a function of both situational (i.e. manipulations of the Prisoner's Dilemma Game's payoff structure) and personality differences (i.e. individual differences in personality and motivational traits). Moreover, our included situational variables and personality features did not interact with each other and were about equally impactful in shaping cooperation. Crucially, however, despite the significant behavioural differences across game variants, considerable consistency in choices was found as well, which suggests that the game's motivational basis reliably impacts choice behaviour in spite of situational and personality variations. We discuss implications for theorizing on mixed‐motive situations and elaborate on the question how cooperation can be promoted. © 2018 European Association of Personality Psychology     

Brief encounters and available places to land

In this paper the author addresses the process of ending in brief therapy. While recognizing the importance of attending to the symbolic meaning of the ending itself and the need to interpret this as it manifests in the transference, he points out the limitations of such an approach. He highlights the significance of the environment of interpersonal relationships and family systems and the wider communities in which the client lives. He suggests that the therapist needs to assess the extent to which these can provide an environment that facilitates the client's development and working through as the therapy ends. The therapist needs to establish whether the patient will have an available place to land, and one that provides sufficient security and safety for the client's onward journeying and exploration without the therapist. The author's conceptualization of 'landing at the end of brief therapy' links together Malan's triangles of insight with Sullivan's concept of the ordinary solution and selective inattention and Gustafson's concept of dilemmas to add depth to the therapeutic effectiveness with which the practitioner can approach brief therapy in general, and the ending in particular. The article concludes with a case example that illustrates these themes.     

主体的复归与现象学的先验转向

现象学的先验转向是由意义自在转向先验主体,由完全悬置自我到复归主体,这一方面是由于观念自在论的种种困难所促成,另一方面主体主义哲学惟有通过先验转向才能克服其主观性悖论,先验观念论是主体主义哲学最后和最高的形式,而这种最高形式中也隐藏着先验主体的一些理论困难。     

合作指数与描述方式对儿童囚徒困境博弈中合作行为的影响

本研究采用囚徒困境任务,考察了91名10~12岁儿童和101名成人在博弈决策中合作行为的特点。并分别考察合作指数和描述方式这两个变量对个体合作性的影响。结果表明:(1)描述方式对儿童的合作行为有显著影响,表现为"回避"描述中较之"趋向"描述有更多合作行为,而描述方式对成人则无影响。(2)儿童对合作指数不敏感,平均合作率显著高于成人,表现出合作倾向;成人平均合作率随合作指数的升高而升高,但始终处于几率水平之下,表现出竞争倾向。     

Group Communication During Resource Dilemmas: 4: The Effect of Group Size

Previous theory and research implies that increasing the size of groups facing resource dilemmas results in poorer outcomes, but no previous study has allowed for communication among group members. The present study relates group size with communication content, task outcomes, and participant perceptions of their experience. With communication, actual group size was irrelevant; to the extent that groups chose to cooperate, outcomes were more equal within groups and participants had more positive perceptions. Greater information exchange and negative maintenance talk was related with less equal outcomes and more negative perceptions; more discussion relevant to specific strategy was associated with more equal outcomes. Findings are instructive concerning the genesis and role of group cooperation.     

Unequal but not separate: Emergence of rich–poor cooperation in resource exchange

Addressing inequality is a critical challenge for society as a whole and requires sustained efforts to promote fairness and opportunity for all. Filling in the resource gap across social classes is essential in reducing inequality. Previous studies have revealed that ingroup favouritism hinders the rich from cooperating with the poor and expands the wealth gap. Nevertheless, how to find ways of narrowing the gap between the rich and the poor remains an open question. Inducing rich–poor cooperation could be effective in eliciting resource flow across classes. In this study, two experiments using a modified Prisoner's Dilemma game were conducted in Japan (N = 213) and China (N = 150) to examine whether highlighting partners' cooperativeness under permeable group boundaries induces rich–poor cooperation. All participants were allocated to the rich group and participated in the game with programmed rich- or poor-group partner bots, whose cooperation rates were manipulated. Despite the initial resource disparities between participants and the partner bots, participants were more likely to select and cooperate with cooperative poor-group partners than with non-cooperative rich-group partners. Generalized trust played an important role in the enhancement of rich–poor cooperation. The findings shed light on the possibility of reducing inequality and promoting social mobility in society.     

Commands as Divine Attributes

Theories of ethics that attempt to incorporate divine speech or commands as necessary elements in the construction of moral obligations are often viewed as vulnerable to a challenge based on the so‐called Euthyphro dilemma. According to this challenge, opponents of theistic ethics suppose that divine speech either informs one of a preexisting set of values and obligations, which makes it inconsequential, or is entirely arbitrary, which makes it irrational. This essay analyzes some of the debates on the nature of divine commands in eleventh‐century works of Islamic jurisprudence (u?ūl al‐fiqh). I show that Mu?tazilī jurisprudents advanced the view that divine commands were actions performed in time that had concrete manifestations, while Ash?arīs argued that divine speech in general, and commands in particular, were eternal divine attributes. After exposing certain weaknesses in the Euthyphro‐inspired objections to theistic ethics, I argue that the Ash?arī idea of commands as divine attributes is a promising move for scholars interested in defending a divine command view of moral obligation.     

Understanding cooperation in the Prisoner’s Dilemma game

In the standard one-shot Prisoner’s Dilemma game, participants often choose to cooperate, when the optimal strategy is to defect. This puzzling finding has attracted considerable interest both in terms of possible computational frameworks for modeling human judgment, but also regarding the more general debate of human altruism. In this research, we ask how much of human behavior in this task can be explained by a putative bias for cooperative behavior and whether this, in turn, is influenced by personality. We compared performance on the standard task with performance on a matched neutral one; we manipulated the optimal strategy (defect or cooperate); and we manipulated the amount of payoff for responding optimally. Results revealed little evidence for a bias for cooperative behavior, but significant associations with the personality factors of Behavioural Activation System (BAS) Reward Responsivity and Agreeableness were found. These findings are discussed in terms of the attempt to explain judgment in one-shot, Prisoner’s Dilemma tasks with statistical or probabilistic models.
