Human cognitive abilities: A survey of factor analytic studies

In his Preface the author' says that he started out to review all the more important theories upon the topics ordinarily discussed under human motivation but soon found himself more and more limited to the presentation of his own point of view. This very well characterizes the book. It is a very personal product. It is an outline with some defense of the author's own thinking about instincts and appetites and sentiments and how they function in human behavior. And as the author draws so heavily upon James and McDougall, especially the latter, the book may well be looked upon as a sort of sequel to their efforts. There is a thought-provoking distinction presented between instinct and appetite. An instinct is said to be aroused always by something in the external situation; and, correspondingly, an appetite is said to be aroused by sensations from within the body itself. This places, of course, a heavy emphasis upon the cognitive factor in all instinctive behaviors; and the author prefers to use the cognitive factor, especially the knowledge of that end-experience which will satisfy, as a means of differentiating one instinct from another. In this there is a recognized difference from McDougall who placed more emphasis for differentiation upon the emotional accompaniment. The list of instincts arrived at by this procedure is much like that of McDougall, although the author is forced by his criteria to present the possibility of food-seeking and sex and sleep operating both in the manner of an appetite and also as an instinct. The Shand-McDougall concept of sentiment is taken over and used in the explanation of moral motivation. There is the development within each personality of a sentiment for some moral principle. But this sentiment is not a very powerful motivating factor. It is reinforced by social pressures and by religion, which is treated as an effort of finite man to live in harmony with the infinite reality. Those whose psychological thinking is largely in terms of McDougall will doubtless find this volume a very satisfying expansion; but those who are at all inclined to support their psychological thinking by reference to experimental studies will not be so well pleased. The James-Lange theory, for example, is discussed without mention of the many experimental studies which it has provoked. Theoretical sources appear in general to be preferred to experimental investigations.

Social scientists often estimate models from correlational data, where the independent variable has not been exogenously manipulated; they also make implicit or explicit causal claims based on these models. When can these claims be made? We answer this question by first discussing design and estimation conditions under which model estimates can be interpreted, using the randomized experiment as the gold standard. We show how endogeneity – which includes omitted variables, omitted selection, simultaneity, common-method variance, and measurement error – renders estimates causally uninterpretable. Second, we present methods that allow researchers to test causal claims in situations where randomization is not possible or when causal interpretation could be confounded; these methods include fixed-effects panel, sample selection, instrumental variable, regression discontinuity, and difference-in-differences models. Third, we take stock of the methodological rigor with which causal claims are being made in a social sciences discipline by reviewing a representative sample of 110 articles on leadership published in the previous 10 years in top-tier journals. Our key finding is that researchers fail to address at least 66% and up to 90% of design and estimation conditions that make causal claims invalid. We conclude by offering 10 suggestions on how to improve non-experimental research.

On making causal claims : A review and recommendations

Working memory (WM) is a cognitive system that strongly relates to a person’s ability to reason with novel information and direct attention to goal-relevant information. Due to the central role that WM plays in general cognition, it has become the focus of a rapidly growing training literature that seeks to affect broad cognitive change through prolonged training on WM tasks. Recent work has suggested that the effects of WM training extend to general fluid intelligence, attentional control, and reductions in symptoms of ADHD. We present a theoretically motivated perspective of WM and subsequently review the WM training literature in light of several concerns. These include (a) the tendency for researchers to define change to abilities using single tasks, (b) inconsistent use of valid WM tasks, (c) no-contact control groups, and (d) subjective measurement of change. The literature review highlights several findings that warrant further research but ultimately concludes that there is a need to directly demonstrate that WM capacity increases in response to training. Specifically, we argue that transfer of training to WM must be demonstrated using a wider variety of tasks, thus eliminating the possibility that results can be explained by task specific learning. Additionally, we express concern that many of the most promising results (e.g., increased intelligence) cannot be readily attributed to changes in WM capacity. Thus, a critical goal for future research is to uncover the mechanisms that lead to transfer of training.

Being able to work on several tasks at the same time (multitasking) is an important performance aspect of many jobs. Recent research findings pointed out the important role of working memory for multitasking performance in general. To understand more about the role of working memory in predicting the speed and the error aspect of multitasking performance, this research was based on a newly developed and well-elaborated multidimensional model of working memory (Oberauer, Sus, Wilhelm, & Wittmann, 2003). Its 3 dimensions are storage in the context of processing, coordination, and supervision. In addition, attention and reasoning were controlled when predicting multitasking speed and error. A multitasking scenario, a battery of working memory tests, a battery of reasoning tests, and 2 attention tests were administered to 135 participants. As expected working memory was the best predictor of multitasking performance, followed by reasoning and attention. Working memory components showed a differential validity...

Purpose – The ongoing demographic changes in many industrialized countries affect managerial decisions in many ways, and require sound knowledge of systematic age differences in central work-related variables. The current paper aims to address age differences in the experience of work-related stress. Based on life-span approaches, the authors focus on age differences in different components of the work-related stress process and meta-analyze existing empirical studies on the relationship between age and short-term indicators of work-related stress (i.e. irritation). Design/methodology/approach – The authors conduct both a literature review and a meta-analysis of age and indicators of work-related stress. Findings – The literature review revealed that age might affect several components of the stress process at work. However, as these effects are partly conflicting, they might nullify each other in the overall relation between age and stress. Indeed, the conducted meta-analysis showed no general correlatio...

Age and work-related stress: a review and meta-analysis

Two multivariate studies examined the applicability of the theory of planned behavior in gauging students' attitudes toward mathematics, as well as the predictive power of mathematics attitudes in explaining students' grades in mathematics. Middle-school students from the United States (N = 382) and Belarus (N = 339) participated. Confirmatory factor analysis supported the viability of the theory for both samples. The analyses revealed that between 25% and 32% of the variance in mathematics grades could be explained by the theory of planned behavior components. In fact, 17% of the variation in test grades could be explained by the theory of planned behavior over and above the effects of mathematics ability test scores. Mean score differences between countries were small (ds = .15 to .27), with Belarusian students scoring more highly on attitudes and control but less highly on subjective norms and intentions. The article concludes with discussion of potential interventions and the need to expand results to different age groups and achievement domains, as well as the need for longitudinal and cross-cultural research
