On the current status of the evolutionary theory of behavior dynamics

The evolutionary theory of behavior dynamics is a complexity theory that instantiates the Darwinian principles of selection, reproduction, and mutation in a genetic algorithm. The algorithm is used to animate artificial organisms that behave continuously in time and can be placed in any experimental environment. The present paper is an update on the status of the theory. It includes a summary of the evidence supporting the theory, a list of the theory's untested predictions, and a discussion of how the algorithmic operations of the theory may correspond to material reality. Based on the evidence reviewed here, the evolutionary theory appears to be a strong candidate for a comprehensive theory of adaptive behavior.     

Identification complexity and conflict: how multiple identifications affect conflict across functional boundaries

We integrate insights from the social identity complexity and dual identification literature to explore the influence of workplace identification on cross-functional conflicts at work. We propose that patterns of identification across multiple identity targets will affect the development of cross-functional conflicts within an organization. We test our hypotheses in a two-wave study of 156 military personnel over a period of 4 months, finding support for our propositions. Specifically, we find that less complex patterns of identification (defined as dominant identification with a single workplace identity) are associated with higher increases in process, task and relationship conflict during cross-functional working, compared to complex patterns of identification (identification with two or three targets) and weak identification. These findings have important implications for cross-functional working, and also provide new insights into the role of identification complexity in shaping workplace outcomes.     

Decision-making in rectal and colorectal cancer: systematic review and qualitative analysis of surgeons’ preferences

Surgeons are experiencing difficulties implementing recommendations not only owing to incomplete, confusing or conflicting information but also to the increasing involvement of patients in decisions relating to their health. This study sought to establish which common factors including heuristic factors guide surgeons’ decision-making in colon and rectal cancers. We conducted a systematic literature review of surgeons’ decision-making factors related to colon and rectal cancer treatment. Eleven of 349 identified publications were eligible for data analyses. Using the IRaMuTeQ (Interface of R for the Multidimensional Analyses of Texts and Questionnaire), we carried out a qualitative analysis of the significant factors collected in the studies reviewed. Several validation procedures were applied to control the robustness of the findings. Five categories of factors (i.e. patient, surgeon, treatment, tumor and organizational cues) were found to influence surgeons’ decision-making. Specifically, all decision criteria including biomedical (e.g. tumor information) and heuristic (e.g. surgeons’ dispositional factors) criteria converged towards the factor ‘age of patient’ in the similarity analysis. In the light of the results, we propose an explanatory model showing the impact of heuristic criteria on medical issues (i.e. diagnosis, prognosis, treatment features, etc.) and thus on decision-making. Finally, the psychosocial complexity involved in decision-making is discussed and a medico-psycho-social grid for use in multidisciplinary meetings is proposed.     

Relational categories are more mutable than entity categories

Across three experiments, we explore differences between relational categories—whose members share common relational patterns—and entity categories, whose members share common intrinsic properties. Specifically, we test the claim that relational concepts are more semantically mutable in context, and therefore less stable in memory, than entity concepts. We compared memory for entity nouns and relational nouns, tested either in the same context as at encoding or in a different context. We found that (a) participants show better recognition accuracy for entity nouns than for relational nouns, and (b) recognition of relational nouns is more impaired by a change in context than is recognition of entity nouns. We replicated these findings even when controlling for factors highly correlated with relationality, such as abstractness–concreteness. This suggests that the contextual mutability of relational concepts is due to the core semantic property of conveying relational structure and not simply to accompanying characteristics such as abstractness. We note parallels with the distinction between nouns and verbs and suggest implications for lexical and conceptual structure. Finally, we relate these patterns to proposals that a deep distinction exists between words with an essentially referential function and those with a predicate function.     

Links between relational aggression,parenting and personality among adolescents

The aim of this cross-sectional study was to examine the mediating role of behavioral inhibition system, referring to the inhibition of behavior, and behavioral activation system (BAS), related to impulsivity, in the association between perceived parenting behaviors and relational aggression. It simultaneously investigated the moderating effects of callous-unemotional (CU) traits in this association in a sample of 261 (127 girls) Greek junior high school students who completed a self-report questionnaire. Results of the mediation analyses revealed that BAS was a partial mediator in the relationship between low parental psychological autonomy and relational aggression, as well as between low parental behavioral control and relational aggression. The effect of low parental psychological autonomy on relationally aggressive behavior was also significantly stronger when CU traits were present (moderator). The results emphasize that both individual and interpersonal factors should be taken into consideration when studying relational aggression.     

Ethical Challenges of Personal Disclosure in Gaining Entry with Religious Congregations

This is a story about learning how to navigate my social identities as a non‐religious gay man attempting to conduct data‐based consultation with a religious congregation. Beyond my own growth in knowing myself better, this story speaks to the larger ethical challenge of how we build trust in community relationships, and in particular how much of our personal selves we need to disclose in the process of an individual or group deciding to work with us. Individuals and groups make decisions to work with us based on who they perceive us to be; thus, what is our ethical obligation to disclose aspects of who we are to promote full informed consent? To illustrate this ethical challenge of personal disclosure, I tell the story of discussions I had with three different religious leaders and a congregational committee about potentially working together. Throughout these stories, I reflect on my own messy process of growth as a window into the more general question of how we navigate our identities and values as community psychologists in the work we do with communities.     

Childhood inhibitory control and adolescent impulsivity and novelty seeking as differential predictors of relational and overt aggression

Impulsivity is commonly conflated with novelty seeking, but these traits are conceptually independent and hold different predictive implications. Using a multi-informant, longitudinal design, we examined childhood inhibitory control, as well as adolescent impulsivity and novelty seeking, as predictors of aggression in a sample of 976 twins. Lower childhood inhibitory control and higher adolescent impulsivity predicted both overt and relational aggression in regression analyses that accounted for sex, puberty status, age, and socioeconomic status. As predicted, novelty seeking did not predict aggression, a finding that supports its independence from impulsivity.     

Impact of induced joy on literacy in children: does the nature of the task make a difference?

This research examined whether induced joy influences fifth graders’ performance in literacy tasks. Children were asked to recall a joyful experience, used as a joy induction, before completing either a grammar (Study 1) or textual comprehension task (Study 2). The grammar task involved understanding at the surface level and retrieval of appropriate declarative and procedural knowledge, but limited elaboration unlike the textual comprehension task, which tackled inference generation. By differentiating tasks based on depth of processing required for completion we aimed at testing the validity of two concurrent hypotheses: that of a facilitating effect and that of a detrimental effect of induced joy. Compared to controls, joy induced children showed better performance on the grammar task – specifically children with lower language ability. No differences across groups emerged as a function of joy induction on the text comprehension task. Results are discussed with respect to emotion effects on cognition.     

Stability and Change in Cognitive Behavior Therapy: Considering the Implications of ACT and RFT

Acceptance and Commitment Therapy (ACT) and Relational Frame Theory (RFT) are part of the new wave of treatments and analyses that seem to be emerging in cognitive behavior therapy. In this article, data in support of these new approaches are provided, and evidence that ACT works through different processes than traditional CBT are presented. The integrative proposals of Ciarrochi and Robb, and Ciarrochi, Robb, and Godsell are then considered. In the long run, whether such integrations are useful is an empirical matter, but concerns are raised about the effects of focusing on the content of beliefs, and the role of logical–empirical challenges to belief.
