Case-Based Planning: A Framework for Planning from Experience

This article presents a view of planning as a task supported by a dynamic memory. This view attempts to ingegrate models of memory, learning, and planning into a single system that learns about planning by creating new plans and analyzing how they interact with the world. We call this view of planning case-based planning. A case-based planner makes use of its own past experience in developing new plans. It relies on its memory of observed effects, rather than a set of causal rules, to create and modify new plans. Memories of past successes are accessed and modified to create new plans. Memories of past failures are used to warn the planner of impending problems, and memories of past repairs are called upon to tell the planner how to deal with them. This view of planning from experience supports and is supported by a learning system that incorporates new experiences into the planner's episodic memory. This learning algorithm gains from the planner's failures as well as its successes. Successful plans are stored in memory, indexed by the goals they satisfy and the problems they avoid. Failures are also stored and indexed by the features in the world that predict them. By storing failures as well as successes, the planner is able to anticipate and avoid future plan failures. Case-based planning is aimed at improving planning behavior in three areas: failure avoidance, plan repair, and plan reuse. It also attempts gains over current learning systems, in that the learning is driven by the functional needs of a planner.     

Knowing minds, controlling actions: the developmental relations between theory of mind and executive function from 2 to 4 years of age

This longitudinal study examined the concurrent and predictive relations between executive function (EF) and theory of mind (ToM) in 82 preschoolers who were assessed when they were 2, 3, and 4 years old. The results showed that the concurrent relation between EF and ToM, after controlling for age, verbal ability, and sex, was significant at 3 and 4 years of age but not at 2 years of age. Hierarchical regression analyses showed that EF at age 2 significantly predicted ToM at age 3 and that EF at age 3 significantly predicted ToM at age 4, over and above the effects of age, verbal ability, and prior performance on ToM tasks. However, ToM at ages 2 and 3 did not explain a significant amount of variance in EF at age 4. Bootstrap procedures revealed that verbal ability at age 3 fully mediated the relation between ToM at age 2 and EF at age 4.     

Convergent, but not divergent, thinking predicts susceptibility to associative memory illusions

The relationship between creativity and susceptibility to associative memory illusions in the Deese/Roediger-McDermott procedure was investigated using a multiple regression analysis. Susceptibility to false recognition was significantly predicted by performance on a measure of convergent thinking (the Remote Associates Task) but not by performance on a measure of divergent thinking (the Alternative Uses Task). These findings suggest that the ability to engage in convergent (but not divergent) thinking underlies some of the individual variation in susceptibility to associative memory illusions by influencing the automaticity with which critical lures are activated at encoding.     

The Impact of Feminist Attitudes on the Relation between Racial Awareness and Racial Identity

This study examined the role of liberal and inclusive feminist attitudes in the development of a positive racial identity in a sample of White female undergraduates in the Midwestern United States. Participants (N?=?90) provided self-report data on their racial awareness, liberal and inclusive feminist attitudes, racial identity and demographic information. The main research question was how and to what extent liberal and inclusive feminism influence the relationship between racial awareness and racial identity. Building on conceptual scholarship on identity theory and the intersectionality, results indicated that the relation between racial awareness and racial identity was partially mediated by inclusive feminist attitudes but not by liberal feminist attitudes. The results suggest that a specific type of feminism, which takes into account the experience of race, plays a significant role in our understanding of how White women develop a positive White identity. Results highlight the intersection of race and gender in college student development and have potential implications for administrative responses to student adjustment in increasingly diverse college environments.     

Differentiating crisis incidents: A replication study using the action systems model

Crisis incidents are volatile situations that can pose significant risk to those involved and to law enforcement. The idiosyncratic conditions that lead to such incidents, as well as their volatility, often militate against consistent explanatory models. However, the application of overarching paradigms, such as the action systems model, has shown some promise in imposing order in the domain. Recent research has successfully differentiated crisis incidents into the four distinct modes of the action systems model: conservative, adaptive, integrative, and expressive. The purpose of this paper is to attempt to replicate this recent study using 242 cases from the United States, Ireland, Canada, and Sweden. Data analysis involves smallest space analyses and constrained multidimensional scaling. Although the results supported the underlying structure of original proposed behavioural model, there are a few deviances. These differences along with the potential influence of cultural variations, offence variable selection, the type of incident, and the sample under scrutiny are discussed. It is evident that there remain several challenges, and further research is required, prior to developing a unified framework.     

Characteristics Associated With Individuals’ Caring,Just, and Brave Expressions of the Tendency to Be a Moral Rebel

Extending previous research on the characteristics associated with adolescents’ general tendency to be a moral rebel (Sonnentag & Barnett, 2016), the present study examined the roles of moral identity and (general and situation-specific) moral courage characteristics on 3 (i.e., caring, just, and brave) expressions of the tendency to stand up for one’s beliefs and values despite social pressure not to do so. Results revealed that general and situation-specific moral courage characteristics are important motivators of individuals’ caring, just, and brave expressions of the tendency to be a moral rebel, especially when they possess a relatively strong moral identity.     

Casino Gambling and the Family: Exploring the Connections and Identifying Consequences

Although sanctioned by state governments and widely popular across the United States, gambling remains a controversial activity. For example, casino gambling may be legal and popular, but many believe squandering money is harmful and deviant. People from all backgrounds visit casinos. However, older adults comprise a major portion of the gambling clientele. Along with this have come reports of a wide variety of negative outcomes. Yet, few studies have investigated the relationship between gambling and the family. We use a qualitative in-depth interview grounded theory approach with 34 adults aged 62–88 to investigate the relationship between gambling and family consequences. We explore the impact of gambling on the family with the active aging concept as well as the codependency and sociocultural models of addiction. They offer new ways to understand mild to serious deviance among older adults.     

Deciding Between Work and Family: An Episodic Approach

This study examined work–family conflict decision‐making based on a within–person, episodic approach. Based on 274 episodes across 78 individuals, we investigated the frequency of decisions that result in work interference with family (WIF) versus family interference with work (FIW), as well as the relation of work and family situational variables and previous work–family conflict (WFC) episodes on those decisions. No difference in the frequency with which participants reported WIF episodes versus FIW episodes was observed. Results indicated that work/family role sender pressure, work/family instrumental support, work/family activity importance, work emotional support, and the direction of the previous WFC decision each predicted WFC decisions. Dominance analysis indicated that role sender pressure was the most important predictor. In addition, we compare and discuss within‐person variation with between‐person variation. Contributions of the study to work–family research and practice are discussed.
