Research on top management team (TMT) diversity has grown over the past decade as organizations are increasingly recognizing the purported benefits of diverse perspectives. In synthesizing recent research, we review the current state of the top management team diversity literature to answer for questions: (1) What features of TMT contexts make diversity an important consideration? (2) What types of diversity are most influential to team and organizational outcomes? (3) What are the mechanisms through which TMT diversity influences functioning? and (4) How do contexts shape the relationship between TMT diversity and performance outcomes? Based on our review, we highlight the inherent complexities of conceptualizing, measuring, evaluating, and understanding top management team diversity.
Self-control – the ability to alter unwanted impulses and behavior to bring them into agreement with goal-driven responses – is key during adolescence. It helps young people navigate through the myriad challenges they encounter while transitioning into adulthood. We review empirical milestones in our understanding of how individual differences in adolescent self-control exist and develop. We show how the use of molecular genetic measures allows us to move beyond nature versus nurture, and actually investigate how both nature and nurture explain individual differences in self-control. By highlighting the role of gene-environment correlations and gene-environment interactions, this paper aims to enthuse fellow researchers, with or without a background in genetics, to apply genetically sensitive designs too.
We present a broad notion of norms that can accommodate many of its interdisciplinary variants and offers a framework to ask questions about norm change. Rather than examining community norm change, we focus on changes in the individual's norm representations. These representations can be characterized by six properties (including as context specificity, deontic force, prevalence), and we examine which of the properties change as a result of norm learning and norm teaching. We first review research insights into norm learning based on observation, imitation, and various forms of inference. Then we examine norm learning that results from teaching, specifically teaching by modeling and demonstration, communication and instruction, and evaluative feedback. We finally speculate about how different kinds of norm change in a given community foster different kinds of norm learning in the individual community member.
It is increasingly recognized that successful self-control is not only determined by sheer willpower, but also by people's beliefs about self-control. While early research has provided evidence that people's implicit theories can moderate their subsequent self-control performance, recent research considers the role of metacognition in self-control more comprehensively. In this review, we present an overview of recent advances in the field, emphasizing self-control beliefs and their potential impact on self-control outcomes. We also stress lay beliefs about self-control as an overlooked topic and promising avenue for future research.
