Leadership and the fate of organizations

This article concerns the real-world importance of leadership for the success or failure of organizations and social institutions. The authors propose conceptualizing leadership and evaluating leaders in terms of the performance of the team or organization for which they are responsible. The authors next offer a taxonomy of the dependent variables used as criteria in leadership studies. A review of research using this taxonomy suggests that the vast empirical literature on leadership may tell us more about the success of individual managerial careers than the success of these people in leading groups, teams, and organizations. The authors then summarize the evidence showing that leaders do indeed affect the performance of organizations--for better or for worse--and conclude by describing the mechanisms through which they do so.     

Advancing the dialogue between inner and outer empiricism: A comment on O’Nualláin

In a recent contribution to New Ideas in Psychology, Seán O’Nualláin draws out a distinction between inner and outer empiricism, and suggests that consciousness research can benefit from analysis in both directions, that is, via the exploration of facts and relations that facilitate a third-person understanding of consciousness (by reference to an analysis of the structures, processes, and functions of the brain) and via the direct exploration of conscious experience itself, both in terms of its computational (content filled) and non-computational (content empty) aspects. In positing a substrate of subjectivity independent of the contents of consciousness (and, more specifically, a state of “nothingness”), Ò’Nualláin follows a long tradition deeply rooted in mythical, religious, and esoteric schools of belief and practice. Although there is considerable debate amongst philosophers, psychologists, and neuroscientists as to whether or not a non-computational view of consciousness is viable, O’Nualláin accepts that such a possibility does exist. Further, he suggests that a dialogue between the inner and outer empiricists will be fruitful. In this comment I, critique Ò’Nualláin's initial thoughts on the subject and draw out a series of useful distinctions that will help to advance the dialogue between inner and outer empiricism. Critical amongst these distinctions is explicit reference to (1) ontological and epistemological interdependencies in consciousness research, and (2) states of consciousness that describe the transition from “mindfulness” through “nothingness” to “no-mind”.     

Stressors and Stress Reactions Among University Personnel

A large, ethnically diverse, and representative sample of university workers in administrative, instructional, and blue-collar/clerical support categories were administered a battery of questionnaires designed to assess job and nonwork stress, biopsychosocial reactions to stress, emotionality, medical symptoms and utilization, and perceived social support, among other variables. A total of 831 participants returned questionnaires. The principal results showed that job and nonwork stress correlated positively with behavioral, cognitive, and physiological reactions to stress as well as with negative emotionality. Job and nonwork stress correlated meaningfully with medical symptoms; nonwork stress also correlated at a useful level with reported medical utilization. Social support did not generally modulate reports of stress or reactions to stress. It was also found that support staff reported higher levels of nonwork stress and lower levels of work stress, but that 2 measures of job stress did not differentiate administrative and instructional personnel. Younger staff reported higher levels of job and nonwork stress, and females reported higher levels of nonwork stress, irrespective of job category. The results were discussed in terms of their importance for understanding the nature of stress among personnel on the university campus and in relation to prior research.     

Statistical frequency in perception affects children’s lexical production

Children’s early word production is influenced by the statistical frequency of speech sounds and combinations. Three experiments asked whether this production effect can be explained by a perceptual learning mechanism that is sensitive to word-token frequency and/or variability. Four-year-olds were exposed to nonwords that were either frequent (presented 10 times) or infrequent (presented once). When the frequent nonwords were spoken by the same talker, children showed no significant effect of perceptual frequency on production. When the frequent nonwords were spoken by different talkers, children produced them with fewer errors and shorter latencies. The results implicate token variability in perceptual learning.     

Generalization of Sight Word Accuracy using a Common Stimulus Procedure: A Preliminary Investigation

The need to investigate strategies promoting the generalization of reading skills is well documented. The current study builds upon previous literature by examining the impact of a common stimulus procedure on accuracy of reading generalization words in isolation. The common stimulus procedure used in this study intended to enhance the salience of the orthographic and phonemic features between taught and generalization words by highlighting the common rime structure in each word with a specific color. Taught and generalization words representing four word families were used (e.g., end, et, ell, & en). Using a multiple-baseline design across three participants with a replication of procedures for a fourth student, the impact of the common stimulus on accuracy of reading generalization words was examined. Results demonstrated increased accuracy and stability of responding when common stimulus procedures were implemented.     

Cardiovascular Reactivity During Marital Conflict in Laboratory and Naturalistic Settings: Differential Associations with Relationship and Individual Functioning Across Contexts

Cardiovascular reactivity during spousal conflict is considered to be one of the main pathways for relationship distress to impact physical, mental, and relationship health. However, the magnitude of association between cardiovascular reactivity during laboratory marital conflict and relationship functioning is small and inconsistent given the scope of its importance in theoretical models of intimate relationships. This study tests the possibility that cardiovascular data collected in laboratory settings downwardly bias the magnitude of these associations when compared to measures obtained in naturalistic settings. Ambulatory cardiovascular reactivity data were collected from 20 couples during two relationship conflicts in a research laboratory, two planned relationship conflicts at couples’ homes, and two spontaneous relationship conflicts during couples’ daily lives. Associations between self‐report measures of relationship functioning, individual functioning, and cardiovascular reactivity across settings are tested using multilevel models. Cardiovascular reactivity was significantly larger during planned and spontaneous relationship conflicts in naturalistic settings than during planned relationship conflicts in the laboratory. Similarly, associations with relationship and individual functioning variables were statistically significantly larger for cardiovascular data collected in naturalistic settings than the same data collected in the laboratory. Our findings suggest that cardiovascular reactivity during spousal conflict in naturalistic settings is statistically significantly different from that elicited in laboratory settings both in magnitude and in the pattern of associations with a wide range of inter‐ and intrapersonal variables. These differences in findings across laboratory and naturalistic physiological responses highlight the value of testing physiological phenomena across interaction contexts in romantic relationships.     

Congruency effects in dot comparison tasks: convex hull is more important than dot area

The dot comparison task, in which participants select the more numerous of two dot arrays, has become the predominant method of assessing Approximate Number System (ANS) acuity. Creation of the dot arrays requires the manipulation of visual characteristics, such as dot size and convex hull. For the task to provide a valid measure of ANS acuity, participants must ignore these characteristics and respond on the basis of number. Here, we report two experiments that explore the influence of dot area and convex hull on participants’ accuracy on dot comparison tasks. We found that individuals’ ability to ignore dot area information increases with age and display time. However, the influence of convex hull information remains stable across development and with additional time. This suggests that convex hull information is more difficult to inhibit when making judgements about numerosity and therefore it is crucial to control this when creating dot comparison tasks.
