Additional effects of a cognitive task on dual-task training to reduce dual-task interference

ObjectiveWhen we perform dual-tasks in daily life, task performance is generally reduced. As these reductions in performance (i.e., dual-task interference) are responsible for various accidents such as falls, the repeated practice of dual-task (i.e., dual-task training) is often implemented to reduce dual-task interference. However, the risk of various accidents increases with longer dual-task training, as dual-task interference cannot be avoided. Therefore, it is important to achieve training goals more rapidly during dual-task training. This study sought to determine whether a combination of dual-task training and cognitive tasks would accelerate training effects.DesignThe experimental design included four groups: 1) cognitive task training group, 2) dual-task training group, 3) cognitive task and dual-task training group, and 4) non training group.MethodWe assessed single- and dual-task performance before and after the 2-week training sessions. We adopted a dual-task involving knee extension and an auditory reaction, and used N-back task as a cognitive task. On the other hand, dual-task training was the same method to assess dual-task performance.ResultDual-task interference was reduced in all groups in both the tasks. However, the number of participants in the cognitive task and dual-task training group who achieved a reduction in dual-task cost was significantly higher than those in other groups.ConclusionThese findings could contribute to the development of an effective method for reducing dual-task interference and resolving issues caused by dual-task interference in daily life.     

Consequences of Economic Inequality for the Social and Political Vitality of Society: A Social Identity Analysis

Economic inequality has been found to have pernicious effects, reducing mental and physical health, decreasing societal cohesion, and fueling support for nativist parties and illiberal autocratic leaders. We start this review with an outline of what social identity theorizing offers to the study of inequality. We then articulate four hypotheses that can be derived from the social identity approach: the fit hypothesis, the wealth-categorization hypothesis, the wealth-stereotype hypothesis, and the sociostructural hypothesis. We review the empirical literature that tests these hypotheses by exploring the effect of economic inequality, measured objectively by metrics such as the Gini coefficient as well as subjectively in terms of perceptions of economic inequality, on wealth categorization (of others and the self), the desire for more wealth and status, intergroup hostility, attitudes towards immigrants, prosocial behavior, stereotyping, the wish for a strong leader, the endorsement of conspiracy theories, and collective action intentions. As we will show, this research suggests that economic inequality may have even more far-reaching consequences than commonly believed. Indeed, investigating the effects of economic inequality on citizens' sociopolitical behaviors may be increasingly important in today's turbulent political and social landscape.     

Trauma and Deferred Action in the Reality of Adolescence

In the search for ever earlier determinants of adult pathology many ignore the transformative impact of adolescence. The authors suggest that the reality of adolescent development creates a vulnerability to being overwhelmed. Through deferred action childhood experiences may interact with adolescent realities and omnipotent beliefs to traumatize the adolescent. The authors suggest that trauma in adolescence can be independent both of the intensity of current external exposure or of earlier traumatic experiences.     

Does God Cheat at Dice? Divine Action and Quantum Possibilities

The recent debates concerning divine action in the context of quantum mechanics are examined with particular reference to the work of William Pollard, Robert J. Russell, Thomas Tracy, Nancey Murphy, and Keith Ward. The concept of a quantum mechanical "event" is elucidated and shown to be at the center of this debate. An attempt is made to clarify the claims made by the protagonists of quantum mechanical divine action by considering the measurement process of quantum mechanics in detail. Four possibilities for divine influence on quantum mechanics are identified and the theological and scientific implications of each discussed. The conclusion reached is that quantum mechanics is not easily reconciled with the doctrine of divine action.     

God, Freedom, and Evil: Perspectives from Religion and Science

This paper develops analogies concerning the evolution of dissipative structures in nonequilibrium thermodynamics to interpret irrational human behavior in which one finds a lack of correspondence between the invested means and the consequences observed. In an attempt to positively explain the process of cooperation between the free human person and interacting God, I use philosophical categories of Whitehead's process philosophy in an aesthetic model that opposes composition and performance in a musical symphony. Certainly, the essence of human freedom can be expressed in neither thermodynamical nor aesthetic terms. The models proposed can, however, facilitate our understanding of the mutual relations between God's action in the world and the drama of human free choice of moral evil.

Climate action now: How to fuel a social movement

Our research develops a framework that explores how to fuel the climate movement by accelerating grassroots, community-based climate action. Drawing on insights from consumer psychology, our framework identifies the psychological mechanisms that encourage and motivate people, both individually and collectively, to take climate action, thereby contributing to our understanding of how to advance social action and propel a social movement. Our climate action framework builds on: (1) individuals we describe as climate upstanders who rise up to take climate action with like-minded others, and (2) communities of climate upstanders who engage in collective action aimed at addressing the climate crisis. Our framework expands the field of consumer psychology by redefining the role of consumers to include the practice of social action and broadening the study of consumers to include collective, community-based action. We call on consumer psychologists to research individual and collective consumer practices related to social action and contribute to making social good central to the study of consumer psychology.     

Too great to act in solidarity: The negative relationship between collective narcissism and solidarity-based collective action

Three studies examined the association between narcissistic identification with one’s advantaged in-group and engagement in solidarity-based collective action. Drawing on theory and past research, a negative effect of collective narcissism on solidarity-based collective action was expected. A two-wave longitudinal study (N = 162) found that Polish participants’ narcissistic, but not secure, national identification decreased their willingness to engage in collective action in solidarity with refugees over time. A field study (N = 258) performed during a mass protest against a proposed abortion ban showed that men’s gender-based collective narcissism was a negative predictor of solidarity-based engagement (operationalized as protest behavior and collective action intentions) and this effect was mediated by lowered empathy for women. Finally, a web-based survey (N = 1,992) revealed that heterosexual/cisgender individuals’ collective narcissism was negatively associated with collective action intentions in support of LGBT rights and that this effect was sequentially mediated by increased intergroup anxiety and decreased empathy for LGBT people. Theoretical implications of the present findings, research limitations, and future directions are discussed.     

With or without you: The paradoxical role of identification in predicting joint and ingroup collective action in intergroup conflict

While we have a rich understanding of the motivations of disadvantaged group members to act collectively with their group, especially the important role played by identification, we know less about the disadvantaged's motivations to engage in joint action with the advantaged. This research examines the role of identification in predicting joint and ingroup collective action in intergroup conflicts. Since joint action inherently diffuses the perception of “us versus them”, we propose that identification predicts ingroup action, but not joint action. We also examine conflict intensity as a moderator, and examine how changing identification is linked to change in support for joint action. We test these hypotheses in a three-wave longitudinal study in the Palestinian–Israeli conflict. Results support our hypotheses, demonstrating that identification positively predicts ingroup action but not necessarily joint action, and that when conflict intensifies, changes in identification are negatively related to joint action with outgroup members.     

Pity for economically disadvantaged groups motivates donation and ally collective action intentions

We argue that pity can motivate collective action intentions toward groups that are both politically and economically deprived. We tested this connection in four online surveys and an experiment. In Study 1 (N = 1,007), pity for the Roma in Hungary predicted collective action intentions, which was replicated in Study 2 in connection with refugees in Germany (N = 191) and in Hungary (N = 563). Study 3 (N = 475) demonstrated that for not economically but politically disadvantaged groups (e.g., sexual minorities), pity was not a predictor of ally action. In an experiment (Study 4, N = 447), pity was just as strong a predictor of collective action intentions as outrage on behalf of an economically and politically disadvantaged outgroup. Pity can be a mobilizing emotion when it comes to groups that are both economically and politically disadvantaged; however, outrage remains more important in the absence of economic hardship.
