The effects of a public address system on the off-task behavior of elementary physical education students

The purpose of this study was to determine the effects of teacher feedback delivered via a public address system on the off-task behavior of elementary-school physical education students. A multiple baseline design across three classes was used in this investigation. Results indicated a consistent decline in off-task behavior when the public address feedback system was used.     

Visual speech information for face recognition

Two experiments test whether isolated visible speech movements can be used for face matching. Visible speech information was isolated with a point-light methodology. Participants were asked to match articulating point-light faces to a fully illuminated articulating face in an XAB task. The first experiment tested single-frame static face stimuli as a control. The results revealed that the participants were significantly better at matching the dynamic face stimuli than the static ones. Experiment 2 tested whether the observed dynamic advantage was based on the movement itself or on the fact that the dynamic stimuli consisted of many more static and ordered frames. For this purpose, frame rate was reduced, and the frames were shown in a random order, a correct order with incorrect relative timing, or a correct order with correct relative timing. The results revealed better matching performance with the correctly ordered and timed frame stimuli, suggesting that matches were based on the actual movement itself. These findings suggest that speaker-specific visible articulatory style can provide information for face matching.     

Estimation of Wechsler Adult Intelligence Scale-III index scores with the 7-subtest short form in a clinical sample

A 7-subtest short form of the Wechsler Adult Intelligence Scale-III (WAIS-III) previously demonstrated good comparability in estimating Full Scale and Verbal IQ summary scores, with adequate comparability in estimating Performance IQ. In a mixed clinical sample of 295 patients, the current study assessed the equivalence of the index scores generated from the full and prorated WAIS-III. The results revealed correlations corrected for redundancy of .90, .86, .87, and .75 for the Verbal Comprehension (VCI), Perceptual Organization (POI), Working Memory (WMI), and Processing Speed (PSI) indexes, respectively. Although the 7-subtest short form of the WAIS-III was not designed to estimate index scores, adequate estimates are viable for VCI, POI, and WMI when the goal is to obtain group, rather than individual, data points.     

Observations on the factor structure of the WAIS-R

Confirmatory factor analyses (CFAs) revealed 2 important characteristics of the standardization data of the Wechsler Adult Intelligence Scale Revised. One finding was that Digit Symbol fit better on an attentional factor in younger groups, but fit was better when Digit Symbol loaded on a visual-perceptual factor in older groups. A second observation was that specifying correlated errors or a fourth factor to explain covariance between Block Design and Object Assembly improved model fit in all age groups except 70- to 74-year-olds. The results illustrate the value of CFA and have implications for investigating other samples and other Wechsler tests.     

"Factor analyses of the family assessment device," by Ridenour, Daley, & Reich

Ridenour, Daley, and Reich conducted a series of factor analyses using the correlational matrix of the subscale scores of the Family Assessment Device (FAD), published in Family Process, December, 1999. They conclude that "the FAD subscales be reorganized from their current seven-subscale format" (p. 507). We propose that this suggestion for reorganization is premature and based on the inappropriate application of an "internal consistency" model of scale construction to the FAD. We further suggest that the most important criteria regarding an assessment instrument are those of reliability, validity, and clinical utility. In the absence of this kind of data regarding alternative organizations of the FAD, we believe that the original subscales remain the best choice.     

The structure of goal contents across 15 cultures

The authors investigated the structure of goal contents in a group of 1,854 undergraduates from 15 cultures around the world. Results suggested that the 11 types of goals the authors assessed were consistently organized in a circumplex fashion across the 15 cultures. The circumplex was well described by positioning 2 primary dimensions underlying the goals: intrinsic (e.g., self-acceptance, affiliation) versus extrinsic (e.g., financial success, image) and self-transcendent (e.g., spirituality) versus physical (e.g., hedonism). The circumplex model of goal contents was also quite similar in both wealthier and poorer nations, although there were some slight cross-cultural variations. The relevance of these results for several theories of motivation and personality are discussed.     

Communication strategies to promote spiritual well-being among people with dementia

Declining communication skills in dementia threaten a person's sense of self. Building on enduring capabilities, pastoral visitors can significantly enhance spiritual well-being through the use of individualized, person-centered strategies. This article outlines the primary spiritual needs of older adults with dementia and some general strategies to improve communication based on enduring abilities. Detailed examples illustrate how these personhood-centered strategies can meet spiritual needs by connecting with individuals with dementia through life stories and through helping them to participate in religious life.     

A fairy tale with a twist: pastoral counseling with adoptive families

Adoption counseling often focuses primarily on the enigmatic issues faced by adoptees. Very little attention, however, is pointed in the direction of the adoptive parents and their unique struggles. This article begins by providing some current information on adoption in the United States and ensuing implications for pastoral caregiving. Some of the unique challenges associated with the adoption experience are delineated, primarily focusing on systemic and personal issues faced by many adoptive families. Several practical interventions are suggested for pastoral caregivers working with adoptive families. Finally, the entire adoption experience is framed within a theological perspective offering hope to adoptive parents and adoptees.     

Intra-basolateral amygdala infusions of AP-5 impair or enhance retention of inhibitory avoidance depending on training conditions

Previous evidence has suggested that N-methyl-D-aspartate receptors (NMDARs) in the basolateral amygdala (BLA) are critically involved in the acquisition of aversively based learning tasks. However, the role of NMDARs in the BLA in the consolidation of memory of aversive training has not been well elucidated. In the present study, the NMDAR antagonist AP-5 (1 or 3 microg) was infused into the BLA of male Sprague-Dawley rats immediately before, immediately after, or 6h after training on an inhibitory avoidance task with either a high footshock (HFS; only high dose of AP-5 given) or a low footshock (LFS; both doses of AP-5 given). The 48 h retention of animals given AP-5 (3 microg) immediately before or after HFS training was significantly impaired compared to that of vehicle-controls. In contrast, the retention of rats given AP-5 (3 microg) immediately after LFS training was significantly enhanced compared to that of vehicle-controls. AP-5 (3 microg) infusions administered 6h after training with either an HFS or LFS did not affect retention. These findings suggest that the NMDARs in the BLA are involved in both the acquisition and consolidation of aversive memory. In addition, the AP-5-induced enhancement of memory obtained with LFS training suggests that NMDARs in the BLA are involved in other mechanisms influencing synaptic transmission, in addition to their well-established role in neuroplasticity.     

A counterintuitive hypothesis about employment interview validity and some supporting evidence

This study found mixed support for the hypothesis that the difference in criterion-related validity between unstructured and structured employment interviews is due solely to the greater reliability of structured interviews. Using data from prior meta-analyses, this hypothesis was tested in 4 data sets by using standard psychometric procedures to remove the effects of measurement error in interview scores from correlations with rated job performance and training performance. In the 1st data set. support was found for this hypothesis. However, in a 2nd data set structured interviews had higher true score correlations with performance ratings, and in 2 other data sets unstructured interviews had higher true score correlations. We also found that averaging across 3 to 4 independent unstructured interviews provides the same level of validity for predicting job performance as a structured interview administered by a single interviewer. Practical and theoretical implications are discussed.
