A nonverbal signal in voices of interview partners effectively predicts communication accommodation and social status perceptions.

Abstract: Derivations from nonverbal communications accommodation theory are tested, and this knowledge is extended both theoretically and methodologically. Fast fourier transform and statistical analysis of a low-frequency nonverbal signal-in voices from 25 dyadic interviews between a talk show host and his guests revealed voice convergence between partners. Correlation coefficients from comparisons of partners' voice spectra and factor analysis of the correlation matrix showed that lower status partners accommodated their voices to higher status partners via the nonverbal signal. Student ratings of the social status of the same talk show host and guests were correlated with factor loadings, thereby providing convergent validity of the nonverbal signal as a predictor of social status perceptions and accommodation.

Liquid crystalline light modulating device & material.

Abstract: A new liquid crystalline light modulating cell and material are characterized by liquid crystalline light modulating material of liquid crystal and polymer, the liquid crystal being a chiral nematic liquid crystal (16) having positive dielectric anisotropy and including chiral material in an amount effective to form focal conic and twisted planar textures, the polymer being distributed in phase separated domains (15) in the liquid crystal cell in an amount that stabilizes the focal conic and twisted planar textures in the absence of a field and permits the liquid crystal to change textures upon the application of a field. In one embodiment, the material is light scattering in a field-OFF condition and optically clear in a field-ON condition, while in another embodiment, the material is optically clear in a field-OFF condition and light scattering in a field-ON condition. In still another embodiment, the material exhibits stability at zero field in a colored, light reflecting state, a light scattering state and multiple stable reflecting state therebetween, as well as being optically clear in the presence of a field.

Traumatic Events Among Undergraduate Students: Prevalence and Associated Symptoms

Abstract: This multisite study assessed the prevalence of exposure to traumatic events and associated symptoms among undergraduate students (N = 1,528) using online surveys. Most students (85%) reported having experienced a traumatic event in their lifetime (Time 1) and 21% reported experiencing an event over a 2-month period during college (Time 2). The most common event reported at both time points was the unexpected death of a loved one. Lifetime exposures to family violence, unwanted sexual attention, and sexual assault were associated with higher current distress levels. When nominated as a worst event, sexual assault was associated with the most posttraumatic stress disorder symptoms. Events that caused intense fear, helplessness, or horror and those that were intentionally caused were associated with higher distress levels. Total number of lifetime traumas consistently had the highest associations with distress levels. Implications for counseling psychology practice, training, and research are discussed.

An MMPI-2 Infrequent Response Scale for Use with Psychopathological Populations: The Infrequency-Psychopathology Scale, "F(p).".

Abstract: This article describes the development and initial validation of a new Minnesota Multiphasic Personality Inventory—2 (MMPI-2; J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) scale designed to detect infrequent responding in settings characterized by relatively high base rates of psychopathology and psychological distress. The Infrequency-Psychopathology Scale, F(p), was developed by identifying a set of 27 MMPI-2 items answered infrequently by both inpatients and the MMPI-2 normative sample. The new scale's construct validity was examined through tests of a series of hypotheses derived from an analysis of the reasons for elevated Infrequency (F) and Infrequency-Back (Fb) scores in inpatient settings. The F(p) scale's incremental validity was explored by comparing its performance to that of the F scale. The results of this study suggest that F(p) may be used as an adjunct to F in settings characterized by relatively high base rates of psychopathology and psychological distress. An important feature contributing to the clinical usefulness of the Minnesota Multiphasic Personality Inventory—2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) is the availability of scales that assess the validity of individual test protocols. The importance of appraising the validity of individual test scores was recognized by Hathaway and McKinley (1943), who included two validity scales, Lie (L) and Infrequency (F) in the original version of the MMPI. The F scale was developed as an infrequent-response indicator by identifying 64 items that were answered infrequently in the
