Irrelevant speech and serial recall: Implications for theories of attention and working memory

Irrelevant speech markedly impairs serial recall of visually presented lists, even though the person is asked to ignore the speech. In this, the first major review of the phenomenon, we conclude that (i) the effect occurs in memory rather than at encoding; (ii) within memory, the disruption occurs as a result of a confluence of information at the phonological rather than at the articulatory stage of coding; (iii) speech does not have privileged access to memory, since its disruptive effects may be attenuated by habituation; and (iv) disruption occurs as a result of the changing state of the auditory channel, not as had previously been thought the phonological similarity of visual and auditory streams, and is particularly sensitive to pitch changes in both speech and non-speech stimuli. These conclusions are discussed in the light of two complementary theoretical constructs: a cascading filter system responsible for the access of speech to memory and a system of coding within memory sensitive to changing state of the stream responsible for disruption of serial order. Recommendations are made also for empirical work to refine these constructs.     

PHILOSOPHY, SEXUALITY AND GENDER: MUTUAL INTERROGATIONS

These three papers present a quite diverse and complementary set of answers to the question, "Why Sexuality Matters to Philosophy." They show the ways in which sexuality as an issue may be of interest to philosophers working on a wide range of questions. The theme of sexuality appears as both subject matter and context for the development of scientific theories of human behavior, as a pervasive dimension of the representation of everyday life, and as a social phenomenon raising important questions bearing on the implications of equal citizenship for persons of different genders and sexualities. Sexuality reveals itself as implicated in epistemology and philosophy of science, aesthetics and ethics, political philosophy and jurisprudence. Sexuality as a subject matter provides rich examples for extending the treatment of quite traditional problems. At the same time, by identifying sexuality as a fundamental human phenomenon, fraught with normative implications and closely linked to emotional and bodily life, these papers show how thinking about sexuality may also act to unsettle and redefine certain important areas of philosophical inquiry.     

SIGNIFICANCE TESTS AND CONFIDENCE INTERVALS FOR THE ADVERSE IMPACT RATIO

The two most common methods for assessing adverse impact, the four-fifths rule and the z -test for independent proportions, often produce discrepant results. These discrepancies are due to the focus on practical versus statistical significance, and on differing operational definitions of adverse impact. In order to provide a more consistent framework for evaluating adverse impact, a new significance test is proposed, which is based on the same effect size as the four-fifths rule. Although this new test was found to have slightly better statistical power under some conditions, both tests have low power under the typical conditions where adverse impact is assessed. An alternative to significance testing would be to report an estimate of the adverse impact ratio along with a confidence interval indicating the degree of precision in the estimate.     

Let's be friends: Relational self‐construal and the development of intimacy

Two studies examined the role of relational self‐construal in the development and maintenance of intimacy in roommate relationships. In Study 1, 98 roommate pairs completed questionnaires assessing attitudes toward their relationship. Results showed that high relationals disclosed more personal information than lows, which was then associated with their roommates’ perceptions of relationship quality. In Study 2, 142 roommate pairs followed the Study 1 procedure with a 1‐month follow‐up session for the participants (86% returned). Results replicated the findings of Study 1 and showed reciprocated disclosure from the roommates, followed by increased disclosure by the participants at Time 2. These findings support the H. T. Reis and P. Shaver (1988) intimacy model and indicate the importance of the self‐construal in this interpersonal process.     

A TALE OF TWO CLIMATES: DIVERSITY CLIMATE FROM SUBORDINATES' AND MANAGERS' PERSPECTIVES AND THEIR ROLE IN STORE UNIT SALES PERFORMANCE

Applying Zohar's (2000) multilevel model of organizational climate, this study assessed the main and interactive effects of subordinates' and managers' diversity climate perspectives on store sales performance. Across 654 store units of a large U.S. retail organization, we observed main effects of subordinate and managerial diversity climates on unit sales percentage change and a significant subordinate × manager diversity climate perspective interaction. The greatest sales growth was found in stores wherein subordinates and management perceived highly pro-diversity climates (positive consistency). In contrast, the lowest sales growth was evident for stores in which both subordinates and managers reported less hospitable diversity climates (negative consistency). Our findings underscore the positive financial ramifications of highly consistent perceptions that diversity is valued in a work context.
