Tool use as situated cognition

Vaesen disregards a plausible alternative to his position, and so fails to offer a compelling argument for unique cognitive mechanisms. We suggest an ecological alternative, according to which divergent relationships between organism and environment, not exotic neuroanatomy, are responsible for unique cognitive capacities. This approach is pertinent to claims about primate cognition; and on this basis, we argue that Vaesen's inference from unique skills to unique mechanisms is unwarranted.     

Faculty in Faith-Based Institutions: Participation in Decision-Making and Its Impact on Job Satisfaction

This study examined full-time faculty in Christian, faith-based colleges and universities and investigated the type of impact their participation in the decision-making process had on job satisfaction. Previous studies have examined relationships among faculty at state universities and community colleges, yet little research has been examined in the area of full-time faculty at faith-based universities. This study sampled 145 full-time faculties at faith-based universities and examined the demographic variables of gender, age, years of teaching experience, degree, rank and salary groups, and participation. Regression analysis indicated that there were no significant relationships, while t-tests and analysis of variance (ANOVA) revealed no significant differences. Discussion of the findings focused on possible reasons these findings differ from those in studies investigating public colleges and universities.     

The Dimensionality and Well-being Related Correlates of Work Locus of Control

Abstract

Theoretical and empirical developments with the locus of control construct demonstrate that it is a context-specific multidimensional construct that has implications for stress and well-being. In this paper, the multidimensionality of work-specific locus of control is explored by subjecting Spector's work locus of control scale to principal components analysis. Using samples of 221 university staff and 399 accountants, a two-dimensional structure was uncovered; external agents control and personal control. Correlations with constructs that have been theoretically and empirically associated with locus of control indicate slightly divergent results for the two dimensions, thus demonstrating the importance of treating locus of control as a domain-specific multidimensional construct. In addition, test-retest data with a subsample of 246 accountants suggested that work locus of control may be thought of as a state rather than trait measure.     

Six regularities of source recognition

In recent work, researchers have shown that source-recognition memory can be incorporated in an extended signal detection model that covers both it and item-recognition memory (A. Hilford, M. Glanzer, K. Kim, & L. T. DeCarlo, 2002). In 5 experiments, using learning variables that have an established effect on item recognition, the authors tested further implications of that extended model. The results establish 6 source-recognition regularities that support the model. An important regularity in that set is the linkage of source and item recognition: Any learning variable that increases item recognition increases source recognition.     

Reorganization in coping behavior at 1 1/2 years: dynamic systems and normative change

By the age of 1 year toddlers demonstrate distinct coping habits for dealing with frustration. However, these habits may be open to change and reorganization at subsequent developmental junctures. We investigated change in coping habits at 18-20 months, a normative age for major advances in social cognition, focusing on the dynamic systems principles of fluctuation and novelty at transitions. Specifically, we asked whether month-to-month fluctuation, novel behavioral habits and real-time variability increased at the age of a normative transition, despite individual differences in the content of behavior. Infants were given frustrating toys while their mothers sat nearby without helping, on monthly visits at 14-25 months (before, during and after the hypothesized transition). State space grids representing patterns of behavioral durations were constructed for each episode and compared over age. As predicted, month-to-month fluctuation in grid patterns increased temporarily between 17 and 20 months, partly independently of a concurrent peak in distress, and new behavioral habits replaced old ones at the same age. Coping habits changed differently for high-and low-distressed toddlers. However, changes in real-time variability did not generally meet our expectations.     

Language, embodiment, and the cognitive niche

Embodied agents use bodily actions and environmental interventions to make the world a better place to think in. Where does language fit into this emerging picture of the embodied, ecologically efficient agent? One useful way to approach this question is to consider language itself as a cognition-enhancing animal-built structure. To take this perspective is to view language as a kind of self-constructed cognitive niche: a persisting but never stationary material scaffolding whose crucial role in promoting thought and reason remains surprisingly poorly understood. It is the very materiality of this linguistic scaffolding, I suggest, that gives it some key benefits. By materializing thought in words, we create structures that are themselves proper objects of perception, manipulation, and (further) thought.
