In this article, we attempt to distinguish between the properties of moderator and mediator variables at a number of levels. First, we seek to make theorists and researchers aware of the importance of not using the terms moderator and mediator interchangeably by carefully elaborating, both conceptually and strategically, the many ways in which moderators and mediators differ. We then go beyond this largely pedagogical function and delineate the conceptual and strategic implications of making use of such distinctions with regard to a wide range of phenomena, including control and stress, attitudes, and personality traits. We also provide a specific compendium of analytic procedures appropriate for making the most effective use of the moderator and mediator distinction, both separately and in terms of a broader causal system that includes both moderators and mediators.

Job Demands, Job Decision Latitude, and Mental Strain: Implications for Job Redesign

The Theory of Planned Behaviour (TPB) has received considerable attention in the literature. The present study is a quantitative integration and review of that research. From a database of 185 independent studies published up to the end of 1997, the TPB accounted for 27% and 39% of the variance in behaviour and intention, respectively. The perceived behavioural control (PBC) construct accounted for significant amounts of variance in intention and behaviour, independent of theory of reasoned action variables. When behaviour measures were self-reports, the TPB accounted for 11% more of the variance in behaviour than when behaviour measures were objective or observed (R2s = .31 and .21, respectively). Attitude, subjective norm and PBC account for significantly more of the variance in individuals' desires than intentions or self-predictions, but intentions and self-predictions were better predictors of behaviour. The subjective norm construct is generally found to be a weak predictor of intentions. This is partly attributable to a combination of poor measurement and the need for expansion of the normative component. The discussion focuses on ways in which current TPB research can be taken forward in the light of the present review.

Efficacy of the Theory of Planned Behaviour: a meta-analytic review.

We build on an emerging strategy literature that views the firm as a bundle of resources and capabilities, and examine conditions that contribute to the realization of sustainable economic rents. Because of (1) resource-market imperfections and (2) discretionary managerial decisions about resource development and deployment, we expect firms to differ (in and out of equilibrium) in the resources and capabilities they control. This asymmetry in turn can be a source of sustainable economic rent. The paper focuses on the linkages between the industry analysis framework, the resource-based view of the firm, behavioral decision biases and organizational implementation issues. It connects the concept of Strategic Industry Factors at the market level with the notion of Strategic Assets at the firm level. Organizational rent is shown to stem from imperfect and discretionary decisions to develop and deploy selected resources and capabilities, made by boundedly rational managers facing high uncertainty, complexity, and intrafirm conflict.

Strategic assets and organizational rent

Publisher Summary
This chapter outlines the two basic routes to persuasion. One route is based on the thoughtful consideration of arguments central to the issue, whereas the other is based on the affective associations or simple inferences tied to peripheral cues in the persuasion context. This chapter discusses a wide variety of variables that proved instrumental in affecting the elaboration likelihood, and thus the route to persuasion. One of the basic postulates of the Elaboration Likelihood Model—that variables may affect persuasion by increasing or decreasing scrutiny of message arguments—has been highly useful in accounting for the effects of a seemingly diverse list of variables. The reviewers of the attitude change literature have been disappointed with the many conflicting effects observed, even for ostensibly simple variables. The Elaboration Likelihood Model (ELM) attempts to place these many conflicting results and theories under one conceptual umbrella by specifying the major processes underlying persuasion and indicating the way many of the traditionally studied variables and theories relate to these basic processes. The ELM may prove useful in providing a guiding set of postulates from which to interpret previous work and in suggesting new hypotheses to be explored in future research.

The elaboration likelihood model of persuasion

While most people will agree that there is much overlap between skill and luck, a full understanding of how inextricably bound the two are has yet to be attained. In principle the distinction seems clear. In skill situations there is a causal link between behavior and outcome. Thus, success in skill tasks is controllable. Luck, on the other hand, is a fortuitous happening. Success in luck or chance activities is apparently uncontrollable. The issue of present concern is whether or not this distinction is generally recognized. The position taken here is that it is not. While people may pay lip service to the concept of chance, they behave as though chance events are subject to control. If this is correct, it is of interest to determine the variables responsible for this confusion. … Some observational support for the assertion that people treat chance events as controllable comes from sociologists Goffman (1967) and Henslin (1967). While studying gambling practices in Las Vegas, Goffman noted that dealers who experienced runs of bad luck ran the risk of losing their jobs. Henslin studied dice playing and noted that dice players clearly behave as if they were controlling the outcome of the toss. They are careful to throw the dice softly if they want low numbers or to throw hard for high numbers. They believe that effort and concentration will pay off.

The illusion of control.

A field experiment was conducted to assess the effects of enhanced personal responsibility and choice on a group of nursing home residents. It was expected that the debilitated condition of many of the aged residing in institutional settings is, at least in part, a result of living in a virtually decision-free environment and consequently is potentially reversible. Residents who were in the experimental group were given a communication emphasizing their responsibility for themselves, whereas the communication given to a second group stressed the staff's responsibility for them. In addition, to bolster the communication, the former group was given the freedom to make choices and the responsibility of caring for a plant rather than having decisions made and the plant taken care of for them by the staff, as was the case for the latter group. Questionnaire ratings and behavioral measures showed a significant improvement for the experimental group over the comparison group on alertness, active participation, and a general sense of well-being.

Heads I win, tails it's chance: The illusion of control as a function of the sequence of outcomes in a purely chance task.

Three field experiments were conducted to test the hypothesis that complex social behavior that appears to be enacted mindfully instead may be performed without conscious attention to relevant semantics. Subjects in compliance paradigms received communications that either were or were not semantically sensible, were or were not structurally consistent with their previous experience, and did or did not request an effortful response. It was hypothesized that unless the communication occasioned an effortful response or was structurally (rather than semantically) novel, responding that suggests ignorance of relevant information would occur. The predictions were confirmed for both oral and written communications. Social psychological theories that rely on humans actively processing incoming information are questioned in light of these results. Consider the image of man or woman as a creature who, for the most part, attends to the world about him or her and behaves on the basis of reasonable inference drawn from such attention. The view is flattering, perhaps, but is it an accurate accounting of covert human behavior? Social psychology is replete with theories that take for granted the "fact" that people think. Consistency theories (cf. Abelson et al., 1968), social comparison theory (Festinger, 1954; Schachter, 1959), and attribution theory (Heicler, 1958; Jones et al., 1972; Kelley, 1967), for example, as well as generally accepted explanations for phenomena like bystander (non)intervention (Darley & Latane, 1968), all start out with the underlying assumption that people attend to their
