Leadership & Organizational Behavior

This chapter on mind perception reviews social cognitive research on how individual perceivers draw inferences about the beliefs, desires, intentions, and feelings of others around them, a process that is at once remarkable and nearly ubiquitous. We begin by examining how perceivers do this, discussing research on various inferential sources, including reading situations, faces, behavior, social groups, and the self. We also discuss accounts that address how perceivers might shift between these inferential sources, such as embracing stereotyping in lieu of social projection or vice versa.

Previous research suggests that cortisol can affect cognitive functions such as memory, decision making and attentiveness to threat-related cues. Here, we examine whether increases in cortisol, brought on by an acute social stressor, influence threat-related decision making. Eighty-one police officers completed a standardized laboratory stressor and then immediately completed a computer simulated decision making task designed to examine decisions to accurately shoot or not shoot armed and unarmed Black and White targets.

It is self-evident that performing poorly on a task makes people dissatisfied relative to performing well. How can this negative affect be overcome? We provide an adaptive strategy for dealing with poor performance. Experiment 1 shows that poor performers tend to recruit the highest potential performance as a comparison standard and hence are dissatisfied. However, if they are reminded that they set their own low goals, and that these goals were met, they are as satisfied as better performers.

Sovereign Wealth Funds (SWFs) are state-owned investment funds with combined asset holdings that are fast approaching four trillion dollars. Recently emerging as a major force in global financial markets, SWFs have other distinctive features besides their state-owned status: they are mainly located in developing countries and are intimately tied to energy and commodities exports, and they carry virtually no liabilities and have little redemption risk, which allows them to take a longer-term investment outlook than most other institutional investors.

Particle learning provides a simulation-based approach to sequential Bayesian computation. To sample from a posterior distribution of interest we use an essential state vector together with a predictive and propagation rule to build a resampling-sampling framework. Predictive inference and sequential Bayes factors are a direct by-product. Our approach provides a simple yet powerful framework for the construction of sequential posterior sampling strategies for a variety of commonly used models.

A perennial question facing managers is how much decision latitude to give their employees at work. The current research investigates how decision latitude affects employees' perceptions of managers' personalities and, in turn, their leadership effectiveness. Results from three studies using different methods (two experiments and a survey) indicate an inverted-U shaped relationship between degree of decision latitude and leadership effectiveness perceptions.

A growing literature suggests that even in the absence of any ability to predict returns, holding options on the benchmarks or trading frequently can generate positive alpha. The ratio of alpha to its tracking error appraises a fund's performance. This paper derives the performance-maximizing strategy, which turns out to be a variant of a buy-write strategy, and the least upper bound on such performance enhancement. If common equity indices are used as benchmarks, the potential alpha generated from trading frequently can be substantial in magnitude, but it carries considerable risk.
