Dynamic reasoning and time pressure: Transition from analytical operations to experiential responses

Based upon the Decision Field Theory (Busemeyer and Townsend 1993), we tested a model of dynamic reasoning to predict the effect of time pressure on analytical and experiential processing during decision-making. Forty-six participants were required to make investment decisions under four levels of time pressure. In each decision, participants were presented with experiential cues which were either congruent or incongruent with the analytical information. The congruent/incongruent conditions allowed us to examine how many decisions were based upon the experiential versus the analytical information, and to see if this was affected by the varying degrees of time pressure. As expected, the overall accuracy was reduced with greater time pressure and accuracy was higher when the experiential and analytical cues were congruent than when they were incongruent. Of great interest was the data showing that under high time pressure participants used more experiential cues than at other time pressures. We suggest that the dynamic reasoning paradigm has some future potential for predicting the effects of experiential biases in general, and specifically under time pressure.     

The Collapsing Choice Theory: Dissociating Choice and Judgment in Decision Making

Decision making theory in general, and mental models in particular, associate judgment and choice. Decision choice follows probability estimates and errors in choice derive mainly from errors in judgment. In the studies reported here we use the Monty Hall dilemma to illustrate that judgment and choice do not always go together, and that such a dissociation can lead to better decision-making. Specifically, we demonstrate that in certain decision problems, exceeding working memory limitations can actually improve decision choice. We show across four experiments that increasing the number of choice alternatives forces people to collapse choices together, resulting in better decision-making. While choice performance improves, probability judgments do not change, thus demonstrating an important dissociation between choice and probability judgments. We propose the Collapsing Choice Theory (CCT) which explains how working memory capacity, probability estimation, choice alternatives, judgment, and regret all interact and effect decision quality.      

Families' values and attitudes regarding responsibility for the frail elderly: implications for aging policy

This study examines the norms and values associated with care to disabled and frail aging parents, in particular those with regard to the sharing of responsibilities for care between families and formal services, and this within three age cohorts in Quebec, Canada. It is based on a telephone interview of 1,315 people. Factor analysis yielded four factors: (1) family responsibility; (2) uncompromising family obligations; (3) acceptance of services; (4) distrust of services. Analyses of the data indicate that all three age cohorts consider that families have responsibilities for their aging family members, at the same time that they score very high on the acceptance of service scale. This article discusses these seemingly paradoxical results and their implications for aging policy.     

To be or not to be: the effects of aging stereotypes on the will to live

This study examined whether stereotypes of aging might contribute to decisions the elderly make about when to die. Old and young participants (N=64) were subliminally primed with either negative or positive stereotypes of old age and then responded to hypothetical medical situations involving potentially fatal illnesses. Consistent with our prediction, the aged participants primed with negative stereotypes tended to refuse life-prolonging interventions, whereas the old participants primed with positive age stereotypes tended to accept the interventions. This priming effect did not emerge among the young participants for whom the stereotypes were less relevant. The results suggest that societally-transmitted negative stereotypes of aging can weaken elderly people's will to live.     

Modelling state anxiety in a medical setting: The mediating role of embarrassment

Abstract

Little research has been conducted on the relationship between state anxiety and embarrassment in a medical setting. In the prcsent study, several personality and situational variables were examined as antecedents of state anxiety. A total of 277 patients who had come for an examination either as a response to a melanoma screening programme or due to a dermatological complaint participated in the study. Results showed that purpose of patient visit, physician's recommendation, trait anxiety, and embarrassment, were each correlated with state anxiety. Furthermore, using mediated regression analysis as well as structural equations, embarrassment was found to mediate between the above antecedents and state anxiety. The authors proposed a model linking all the variables and identifying their paths. Theoretical and practical considerations of the findings are discussed.     

Population viability assessment and sensitivity analysis as a management tool for the peri-urban environment

Anthropogenic disturbance occurring within urban ecosystems is often extreme and highly variable. A quantifiable measure of their effect on the persistence of urban wildlife populations would contribute to conservation efforts. This study suggests that population viability assessment, a commonly utilized modeling tool for creating management strategies for rare and threatened wildlife populations, is also appropriate in an urban context. It can be used to create proactive management strategies that quantify the impacts of anthropogenic disturbances and rank a range of management options within an active adaptive framework. To show this, population viability assessment and sensitivity analyses were run to forecast the population trends of a seemingly robust but isolated swamp wallaby (Wallabia bicolor) population living in peri-urban Sydney, Australia; a population exposed to anthropogenic disturbances from towns, hobby farms and roads. Modeling suggested this population was in a slow decline and that predictions were highly dependent upon stochastic events and the precision of reproduction rates. However, a number of management options are identified that will dramatically reduce the risk of total population decline, with complementary options utilized in tandem the most effective.     

Microinsurance: A short history

Twenty years ago, the International Social Security Review published an article that introduced a new term to the vocabulary of development and social protection: Microinsurance. Now, twenty years later, it is suitable to take stock of the contribution of microinsurance towards promoting coverage and social security. The article reviews the main insights gained from 20 years of implementation, including a clear expression of the value proposition of health microinsurance, understanding the demand for microinsurance, the business process for successful implementation, and conditions that must be satisfied for scaling and sustainable operations. It also explains the context that led to a considerable divergence in the microinsurance space. The article offers a discussion of unresolved issues and thoughts about the future of microinsurance. The conclusion of this article is that microinsurance can flourish when the necessary four pillars for its implementation exist, namely mainstreaming through political support, enhanced insurance literacy of the customers, technical assistance to self‐administer the schemes, and availability of seed capital. The sufficient additional condition is that customers perceive microinsurance as offering welfare gains that cannot be obtained by other means.     

Family Therapy Training in Israel*

In Israel the difficulties met with in training social workers in family therapy arise from inherent resistance to change in social and other professional agencies and from insufficient experience in the methodology of training. The family in Israel—a developing country—is undergoing wide-reaching social and cultural changes, which make for additional difficulty in using training models developed in other countries. Nevertheless, graduates of the family therapy program of the Institute for Training and Continued Education of Social Workers in Tel-Aviv, Israel, have shown substantial improvement in several areas of working with problem families.     

Exploring the Adaptive Capacities of Shared Jewish–Arab Organizations in Israel

Nonprofits have unique strategic concerns, including their dependence on external resources, the management of multiple stakeholders, perceptions about their organizational legitimacy as well as their primary focus on the social value of their organizational mission (Stone and Brush 1996). For shared Jewish–Arab organizations in Israel that are seeking to promote a ‘shared society,’ the obstacles in navigating these various challenges are particularly pronounced and require a very unique kind of adaptive capacity (see Letts et al. 1999; Connolly and York 2003; Strichman et al. 2007). Often operating outside of the general consensus, these organizations are faced with the significant challenge of promoting values of partnership, equality and mutual interests among two populations that are often at odds. This research seeks to shed light on how shared Arab–Jewish nonprofits are continually working to strengthen organizational capacities to more effectively carry out their particular organizational mission, given the myriad of challenges they face.
