Processing of written and spoken words: Evidence for common coding

Common processing systems involved during reading and listening were investigated. Semantic, phonological, and physical systems were examined using an experimental procedure that involved simultaneous presentation of two words: one visual and one auditory. Subjects were instructed to attend to only one modality and to make responses on the basis of words presented in that modality. Influence of unattended words on semantic and phonological decisions indicated that these processing systems are common to the two modalities. Decisions in the physical task were based on modality-specific codes operating prior to the convergence of information from the two modalities.     

Effective random seeding of random number generators

To obtain different sequences of values from a random number generating algorithm, we must start with different seed values or discard a variable number of initial samples. For maximum independence among sequences, differences must include the lowest order seed bits, and some generators require one to wait many samples for differences to propagate to the significant bits. While it is straightforward to generate two statistically independent sequences, it is surprisingly difficult to generate three or more such sequences.     

A unified approach to exploratory factor analysis with missing data,nonnormal data,and in the presence of outliers

Factor analysis is regularly used for analyzing survey data. Missing data, data with outliers and consequently nonnormal data are very common for data obtained through questionnaires. Based on covariance matrix estimates for such nonstandard samples, a unified approach for factor analysis is developed. By generalizing the approach of maximum likelihood under constraints, statistical properties of the estimates for factor loadings and error variances are obtained. A rescaled Bartlett-corrected statistic is proposed for evaluating the number of factors. Equivariance and invariance of parameter estimates and their standard errors for canonical, varimax, and normalized varimax rotations are discussed. Numerical results illustrate the sensitivity of classical methods and advantages of the proposed procedures.This project was supported by a University of North Texas Faculty Research Grant, Grant #R49/CCR610528 for Disease Control and Prevention from the National Center for Injury Prevention and Control, and Grant DA01070 from the National Institute on Drug Abuse.

Ego-Identity Achievement and Perception of Risk in Intimacy in Survivors of Stranger and Acquaintance Rape

One hundred twenty-two women participated in a study of the relationship between acquaintance/stranger rape and the respective variables of ego-identity achievement (attainment of self-image during adolescence that integrates one's ideas of what one is and what one wants to be) and perception of risk in intimacy (perception of close interpersonal relationships as a risky proposition). Results showed that compared to women who had not been sexually assaulted, survivors of rape in general reported lower ego-identity achievement and greater perception of risk in intimacy. Focusing on acquaintance rape and stranger rape with age at the time of assault as possible moderator, it was found that lower ego-identity achievement was systematically related to acquaintance rape in women who had been raped during their adolescent years, but not in survivors of rape during adulthood. Perception of risk in intimacy was significantly higher among women who had been raped when adolescents compared to those who had been raped during adulthood, but only in relation to acquaintance rape.     

Sculpting the Body Beautiful: Attachment Style,Neuroticism, and Use of Cosmetic Surgeries

Use of cosmetic surgeries has increased steadily over the last decade, and continues to rise in young and old alike. The purpose of present research was to investigate the relationship of personality to use of cosmetic procedures of various kinds. It was expected that adult attachment style, in particular attachment anxiety, would be positively related to use of cosmetic procedures. Attachment anxiety involves excessive approval seeking and concern over achieving and maintaining the love of significant others (such as romantic relationship partners). Such concerns could, in turn, lead to use of a variety of strategies for maintaining positive regard, including cosmetic surgeries to enhance physical appearance. Results supported this hypothesis, particularly among women. Neuroticism was also related to some procedures, though the relationships were generally weaker than those for attachment anxiety, and largely disappeared in regression analyses that controlled for the separate influence of the two variables.

Testimony,Knowledge, and Epistemic Goals

Various considerations are adduced toshow that we require that a testifier know hertestimony. Such a requirement apparentlyimproves testimony. It is argued that the aimof improving testimony explains why we have anduse our concept of knowledge. If we were tointroduce a term of praise for testimony, usingit at first to praise testimony that apparentlyhelped us in our practical projects, it wouldcome to be used as we now use the word``know'.     

Paradoxical effects of presentation modality on false memory.

Two experiments are reported in which the effects of presentation modality on false memory in recall and recognition are studied. False recall and recognition of critical targets are lower for non-presented items related to a study list when that study list is presented visually than when presented auditorily. This pattern of low levels of false memory for critical targets holds even when participants read the visually presented study items aloud. These results suggest that recollection of visual detail plays a role in the prevention of false memory. However, both the hit rates (true memory) and the false-alarm rates to weakly related distractors (non-critical targets) were higher for visual presentation than for auditory presentation, suggesting that more than one mechanism may underlie false recognition.
