Cognitive style and plebe turnover at the U.S. Naval Academy

Students entering (N = 1,134) the U.S. Naval Academy class of 2000 were administered the Kirton Adaption-Innovation Inventory on the first day of Plebe Summer, a 7-wk. nonacademic training program completed by all entering students in the summer prior to the freshman year. The mean score on Innovation cognitive style for this sample of plebes was approximately a standard deviation lower than those of five other undergraduate student samples from nonmilitary universities. Furthermore, the 98 plebes who voluntarily withdrew before completing the program scored higher on the average on Innovation than those who remained. Findings suggest that, in terms of Person-Organization fit, plebes with a more innovative cognitive style may, perhaps, be less compatible with the regimentation-style climate of the Academy than those with an Adaptive cognitive style. Further research, however, is needed to specify the relationship between Academy students' cognitive style and other important organizational outcomes.     

Zero Anaphora: Transfer of Reference Tracking Strategies from Chinese to English

English contains many nominals that would be absent in Chinese because Chinese makes greater use of zero anaphora, which is an empty grammatical slot in a sentence standing for a previously mentioned referent. Native Chinese and native English speakers were compared in comprehending modified English passages from a standardized reading test with nominals deleted that would be absent in Chinese. In three experiments, Chinese speakers showed superior comprehension as measured by objective multiple-choice questions in this case, but not when no words were deleted or when nominals were deleted that would not be absent in Chinese. These results imply that native Chinese speakers develop reference tracking strategies that they transfer to comprehending English.This research was supported in part by United States Army Research Institute Contracts MDA903-93-K-0010, DASW01-96-K-0010, DASW01-99-K-0002, and DASW01-03-K-0002 to the University of Colorado (Alice Healy, Principal Investigator).We thank Lyle Bourne and Barbara Fox for stimulating discussions about this research. We are also grateful to the Institute of Cognitive Science at the University of Colorado for their support of this research.Experiments 1 and 2 were reported at the International Conference on Functional Approaches to Grammar, Albuquerque, NM, July 25, 1995, and at the 37th Annual Meeting of the Psychonomic Society, Chicago, IL, November 3, 1996, and all three experiments were reported at the 2001 American Association for Applied Linguistics conference, St. Louis, MO, February 24, 2001.     

Stereotype Threat in Men on a Test of Social Sensitivity

This study provides evidence of stereotype threat in men on a test of a feminine ability called social sensitivity, that is, the ability to decode nonverbal cues. Men who were told that the test assessed social sensitivity and produced better scores for women than men performed worse on the test than did men who were told that the test assessed information processing. Because social sensitivity can be an automatic skill and stereotype threat uses mental capacity, this effect was moderated by self-reported strategy usage. Mens performance worsened in the threat condition only when they reported more deliberative and less intuitive strategies for decoding nonverbal cues.     

Essentialism and the Necessity of the Laws of Nature

In this paper I discuss and evaluate different arguments for the view that the laws of nature are metaphysically necessary. I conclude that essentialist arguments from the nature of natural kinds fail to establish that essences are ontologically more basic than laws, and fail to offer an a priori argument for the necessity of all causal laws. Similar considerations carry across to the argument from the dispositionalist view of properties, which may end up placing unreasonable constraints on property identity across possible worlds. None of my arguments preclude the possibility that the laws may turn out to be metaphysically necessary after all, but I argue that this can only be established by a posteriori scientific investigation. I therefore argue for what may seem to be a surprising conclusion: that a fundamental metaphysical question – the modal status of laws of nature – depends on empirical facts rather than purely on a priori reasoning.     

Stressors and child and adolescent psychopathology: moving from markers to mechanisms of risk

In the first half of this review, the authors critically evaluate existing research on the association between stressors and symptoms of psychopathology in children and adolescents. This analysis reveals (a) problems with conceptualizations of stress, (b) variability in measurement of stressors, and (c) lack of theory-driven research. To address these problems, the authors propose a general conceptual model of the relation between stressors and child and adolescent psychopathology. The authors examine basic tenets of this general model in the second half of this article by testing a specific model in which negative parenting mediates the relation between economic stressors and psychological symptoms in young people. Results generally provide support for the specific model as well as for the broader model.     

Sentence interference in the Stroop task

In two experiments on Stroop interference, we examined whether sentences can be processed without the intention of the reader. Participants named the ink colors in which words in sentences were printed, and the ink colors in which the same words, randomly arranged, were printed. In Experiment 1, sentences yielded longer response times (RTs) and more errors than did nonsentences, but only when they included words that were highly relevant to the color-naming task (i.e., color and color-related words). In Experiment 2, sentences yielded more errors than did nonsentences, and sentences in which the color words matched the set of ink colors yielded longer RTs than did nonsentences. The results indicate that sentence processing can be obligatory when the component words are highly relevant to the task.
