Further evaluation of a brief, intensive teacher-training model

The purpose of this study was to further evaluate the outcomes of a model program that was designed to train current teachers of children with autism. Nine certified special education teachers participating in an intensive 5-day summer training program were taught a relatively large number of specific skills in two areas (preference assessment and direct teaching). The teachers met the mastery criteria for all of the skills during the summer training. Follow-up observations up to 6 months after training suggested that the skills generalized to their classrooms and were maintained for most teachers with brief feedback only.     

Behavioral correlates of selected MMPI-2 clinical, content, and restructured clinical scales

In this study, we evaluated the validity of the Restructured Clinical (RC; Tellegen et al., 2003) scales by identifying and comparing behavioral correlates of selected RC scales (RCd, RC2, RC4), their original Clinical scale counterparts (Scale 2, Scale 4), and conceptually related Content scales (DEP, ASP, CYN) in an outpatient clinical sample (N = 150). The results of this study indicate that RC4 is a stronger predictor of several antisocial behaviors than Clinical Scale 4 or the Content Scales ASP and CYN. In contrast, RC2 demonstrated significantly lower correlations with several behaviors conceptually related to depression than its Clinical scale counterpart or DEP. DEP was highly correlated with RCd (r = .91, p < .0001), suggesting that the 2 scales may be measuring similar constructs. Overall, the results of this study demonstrate relatively few differences among the scales selected in their ability to predict extratest behaviors.     

Equivalence of a measurement model of cognitive abilities in U.S. standardization and Australian neuroscience samples

A psychological measurement model provides an explicit definition of (a) the theoretical and (b) the numerical relationships between observed scores and the latent variables that underlie the observed scores. Examination of the metric invariance of a measurement model involves testing the hypothesis that all components of the model relating observed scores to latent variables are equal across groups. The assumption of metric invariance is necessary for simple interpretation of scores. Establishing metric invariance also has implications for interpretation of convergent and divergent validity and patterns of deficit or disability. In this study the equivalence of the measurement model derived from the U.S. Wechsler Adult Intelligence Scale-III standardization sample was compared with a heterogeneous neurosciences sample in Australia. A pattern of strict metric invariance was observed across samples. These results provide evidence of the generality of the model underlying measurement of cognitive abilities.     

Statistical phonetic learning in infants: facilitation and feature generalization

Over the course of the first year of life, infants develop from being generalized listeners, capable of discriminating both native and non-native speech contrasts, into specialized listeners whose discrimination patterns closely reflect the phonetic system of the native language(s). Recent work by Maye, Werker and Gerken (2002) has proposed a statistical account for this phenomenon, showing that infants may lose the ability to discriminate some foreign language contrasts on the basis of their sensitivity to the statistical distribution of sounds in the input language. In this paper we examine the process of enhancement in infant speech perception, whereby initially difficult phonetic contrasts become better discriminated when they define two categories that serve a functional role in the native language. In particular, we demonstrate that exposure to a bimodal statistical distribution in 8-month-old infants' phonetic input can lead to increased discrimination of difficult contrasts. In addition, this exposure also facilitates discrimination of an unfamiliar contrast sharing the same phonetic feature as the contrast presented during familiarization, suggesting that infants extract acoustic/phonetic information that is invariant across an abstract featural representation.     

Preliminary examination of timesharing in United States Air Force ROTC cadets

Previous research has shown that timesharing ability--the ability to perform multiple tasks simultaneously--is related to various indices of aircraft pilots' proficiency. Superior timesharing has also been demonstrated by experienced pilots. The present study examined timesharing of United States Air Force Reserve Officer Training Corps (AFROTC) cadets, who are relatively inexperienced (some with no flying experience). 10 AFROTC cadets (M age = 21.4 yr., SD = 1.0) and 18 noncadets (M age = 19.8 yr., SD = 0.9) were evaluated. Participants performed a tracking task on the Multi-Attribute Task battery in a single-task condition, a dual-task condition, and a tri-task condition. Cadets' tracking performance was superior to that by noncadets in the dual-task and tri-task conditions.     

Co-occurrence of Rape Myth Acceptance, Sexism, Racism, Homophobia, Ageism, Classism, and Religious Intolerance

Rape myth acceptance has been extensively studied. Little research is available, however, on the relationship of this variable to other oppressive belief systems. A sample of 492 male and 506 female college students completed the Illinois Rape Myth Acceptance Scale, the Attitudes Toward Women Scale (short form), the Neosexism Scale, the Modern and Old Fashioned Racism Scale, the Modern Homophobia Scale, a modified version of the Economic Belief Scale, the Fraboni Scale of Ageism, and the Marlowe–Crowne Social Desirability Scale (short form). Because there were no existing measures of intolerance toward multiple religions, the Religious Intolerance Scale was developed for this study (using relevant items from the Godfrey Richman Isms Scale). Findings here suggested that greater racism (both modern and old fashioned), sexism (both modern and old fashioned), homophobia (toward both gay men and lesbians), ageism, classism, and religious intolerance were each associated with greater rape myth acceptance. Moreover, each belief system collectively added to the prediction of rape myth acceptance, although sexism has the highest overlap with rape myth acceptance. Although gender did not moderate the relationship between oppressive belief systems and rape myth acceptance, results, across analyses, did indicate that men reported greater rape myth acceptance than women did. Results point to the interrelatedness of rape myth acceptance, racism, sexism, homophobia, classism, ageism, and religious intolerance.     

Integrating haptic-tactile feedback into a video-capture-based virtual environment for rehabilitation.

Video-capture virtual reality (VR) systems are gaining popularity as intervention tools. To date, these platforms offer visual and audio feedback but do not provide haptic feedback. We contend that adding haptic feedback may enhance the quality of intervention for various theoretical and empirical reasons. This study aims to integrate haptic-tactile feedback into a video capture system (GX VR), which is currently applied for rehabilitation. The proposed multi-modal system can deliver audio-visual as well as vibrotactile feedback. The latter is provided via small vibratory discs attached to the patient's limbs. This paper describes the system, the guidelines of its design, and the ongoing usability study.     

Affective Reactions to the Thought of “God”: Moderating Effects of Image of God

Recent understanding of subjective well-being suggests that it consists of global judgments of life satisfaction, hedonic experiences, and beliefs about facets of one’s life. Traditionally, life satisfaction judgments have been the outcome of interest in studies examining the relationship between religiosity and well-being. Two studies were conducted to look at the interactive effects of personal religious beliefs, namely God images, and environmental stimuli, particularly priming the thought of “God.” The first study examines hedonic experiences, which is one of the information sources when constructing a well-being judgment. A second study attempts to replicate the findings with life satisfaction ratings. Results of the first study showed that one’s image of God as a controlling or non-controlling entity moderated the affective response to being primed to think about God. In particular, those who had a high controlling image of God had a negative affective reaction to the God prime. Results of the second study replicated the pattern of results using life satisfaction ratings as the dependent variable.
