Evaluating anticipatory grief as a moderator of life and marital satisfaction for spousal caregivers of individuals with dementia

It is important to understand the role that anticipatory grief may have in moderating the interaction between relationship quality and marital and life satisfaction to help improve the awareness among professionals when identifying challenges individuals may experience while providing care to their romantic partner. This awareness may then lead to new ways of providing education or intervention to caregivers that may result in higher quality of care to individuals with dementia. The purpose of this study was to provide increasing awareness by evaluating the moderating role of anticipatory grief between perceptions of the relationship and marriage and life satisfaction. The sample of this study consisted of 90 spousal caregivers of individuals with dementia. Multiple regression was used and it was found that attachment and perceived closeness significantly predict satisfaction with life and marriage. Tests of moderation did not demonstrate that anticipatory grief served as a moderator for marital satisfaction or life satisfaction. The findings from the study provide information related to informing and structuring interventions and psychoeducation activities for spousal caregivers.     

Room-temperature coherent manipulation of single-spin qubits in silicon carbide with a high readout contrast

Spin defects in silicon carbide (SiC) with mature wafer-scale fabrication and micro/nano-processing technologies have recently drawn considerable attention. Although room-temperature single-spin manipulation of colour centres in SiC has been demonstrated, the typically detected contrast is less than 2, and the photon count rate is also low. Here, we present the coherent manipulation of single divacancy spins in 4H-SiC with a high readout contrast () and a high photon count rate (150 kilo counts per second) under ambient conditions, which are competitive with the nitrogen-vacancy centres in diamond. Coupling between a single defect spin and a nearby nuclear spin is also observed. We further provide a theoretical explanation for the high readout contrast by analysing the defect levels and decay paths. Since the high readout contrast is of utmost importance in many applications of quantum technologies, this work might open a new territory for SiC-based quantum devices with many advanced properties of the host material.     

Relative Heights of Males and Females in Children's Drawings Taille Relative des Silhouettes Masculines et Fe´minines dans les Dessins d'Enfants Alturas Relativas de las Figuras Masculina y Femenina en los Dibujos de los Niños

Two studies are reported concerning the height of male and female figures in children's drawings. In Study 1, 5 and 7 year olds were asked to draw a man and a lady or a boy and a girl. Adult figures were drawn taller than child figures. For boys, the mean heights of their male and female figures were approximately the same but girls drew their females taller than their male figures. The reason for this was that more girls than boys used different structures (incorporating a skirt or trousers into the drawing) to differentiate their figures; this use of different structures results in a taller drawing of a skirted figure. This finding was replicated in Study 2 in which 7-year-olds were asked to draw a lady in a skirt and another in pyjamas: the skirted figure was taller when it had a different structure from the figure in pyjamas, whereas the mean heights of both figures were approximately the same height when the same structure had been used. Deux travaux de recherche ont étudié la taille des silhouettes masculines et féminines dans les dessins d'enfants. Dans l'étude 1, des enfants de 5 et 7 ans ont dû dessiner un homme et une femme ou un garçon et une fille. Les silhouettes adultes ont été dessinées plus grandes que les silhouettes d'enfants. Les garçons ont dessiné des silhouettes d'hommes et de femmes à peu près de la même taille en moyenne, mais les filles ont dessiné leurs femmes plus grandes que leurs hommes. La raison en est que plus de filles que de garçons utilisaient des structures différentes (en incorporant une jupe ou un pantalon dans le dessin) pour différencier leurs silhouettes; cette utilisation de structures différentes résulte en un dessin plus haut de la silhouette en jupe. Ces résultats se retrouvent dans l'étude 2, où des enfants de 7 ans ont dû dessiner une dame en jupe et une autre en pyjama: la silhouette en jupe était plus haute quand elle avait une structure différente de celle en pyjama, tandis que la hauteur moyenne des deux silhouettes était à peu près la même quand la même structure était utilisée. Se informa de dos estudios relacionados con la altura de las figuras masculina y femenina en los dibujos de los niños. En el Estudio 1, se pidió a niños de 5 y 7 años que dibujan un hombre y una mujer, o un chico y una chica. Las figuras adultas fueron dibujadas con una altura mayor que las figuras de niños. Para los niños, las alturas medias de sus figuras masculinas y femeninas fueron aproximadamente las mismas, pero las niñas dibujaron sus figuras femeninas más altas que las masculinas. La razón para esto fue que más niñas que niños usaron estructuras diferentes (incorporando una falda o pantalones en el dibujo) para diferenciar sus figuras. El uso de estas estructuras diferentes resulta en un dibujo más alto de una figura con falda. Este hallazgo se reprodujo en el Estudio 2, en el que se pidió a niños de 7 años que dibujaran una señora con una falda y otra con un pijama: la figura con falda fue más alta cuando tuvo una estructura diferente a la de la figura con pijama, mientras que las alturas medias de ambas figuras fueron aproximadamente la misma altura cuando la hizo uso de la misma estructura.     

Biological significance attenuates overshadowing, relative validity, and degraded contingency effects

Miller and Matute (1996) showed that blocking is attenuated when the blocked conditioned stimulus (CS) is “biologically significant” (i.e., when the CS has the potential to elicit vigorous responding of any kind). To the extent that blocking is representative of cue competition, this finding suggests that biological significance protects CSs against cue competition effects in general. In the present experiments, we tested this possibility by examining the influence of biological significance of CSs on other examples of cue competition, namely, overshadowing, the relative stimulus validity effect, and the degraded contingency effect in rats. In Experiment 1, we found that intense auditory stimuli induced transient unconditioned lick suppression, thereby indicating that intense sounds were of high inherent biological significance. In Experiment 2A, we found that cues with high inherent biological significance were protected from overshadowing. In Experiment 2B, this finding was extended to cues with high acquired biological significance, which was obtained through prior pairings with a reinforcer of the valence opposite to that used in the overshadowing treatment. In Experiments 3 and 4, we found that cues with high inherent biological significance attenuated the relative validity effect and the degraded contingency effect, respectively. These results lend support to the view that biological significance (inherent and acquired) protects stimuli from cue competition effects, a finding that is problematic for many contemporary theories of learning.     

Functional Movement ScreenTM total score does not present a gestalt measure of movement quality in youth athletes

We aimed to evaluate the internal consistency and factor structure of the Functional Movement Screen (FMS^TM) in youth athletes and quantify differences between individual task score at different stages of maturation. FMS^TM and anthropometric variables were measured in 144 youth athletes (96 female, 48 male). Biological maturation was categorised as before- (<-0.5 years), at- (?0.49–0.50 years) and after- peak height velocity [PHV] (>0.51 years). Internal consistency was poor (Cronbach’s alpha; 0.53, ±90% confidence limit 0.10; ordinal alpha 0.6, ±0.09). Principle component analysis extracted two components, representing 47% of the total variance. Tasks loading highest on component 1 required stability, while those loading highest on component 2 favoured mobility. “Likely” decrements in component 1 tasks were observed before-PHV. In-line lunge (effect size ±90% confidence limit; ?0.47, ±0.49), hurdle step (?0.38, ±0.49), and trunk stability push-up (?0.51, ±0.45), were lower compared with athletes at-PHV and rotatory stability (?0.44, ±0.37) was lower than those after-PHV. Boys’ scored “most likely”, higher (0.73, ±0.28) in trunk stability push-up, and girls “likely” higher in shoulder mobility (0.46, ±0.29). In our population, the FMS^TM is not uni-dimensional, thus total score should be avoided. Clear maturation affects were observed in stability tasks.     

Utility of coding vs. mazes subtests in evaluating giftedness with the WISC-R

A recommendation that Mazes be substituted for Coding in the assessment of giftedness with the WISC-R was investigated by including both subtests in the evaluation of 50 children referred for verification of eligibility. Scaled scores on Mazes were significantly higher than those on Coding for the group, although the proportion of children meeting the established criterion was similar under inclusion of either subtest in the computation of Full Scale Scores. These data offer general support for the selective inclusion of Mazes in this type of assessment.     

Comparison of the relationship between two measures of visual-motor coordination and academic achievement

Scores from Koppitz' scoring system for the Bender-Gestalt and Beery's Developmental Test of Visual-Motor Integration for a group of 86 elementary students referred for psychoeducational evaluation were correlated with Wide Range Achievement Test scores, controlling for WISC-R IQ. Although zero-order correlations of the visual-motor measures with achievement were of moderate magnitude (.33 to.48) and were all statistically significant (p<.01), first-order partial correlations were of lower magnitude (.13 to.22) and half failed to reach statistical significance (p>.05). It was suggested that visual-motor ability may not offer a unique contribution to the prediction of achievement.     

Evaluation of simulated decision making: A response to Ysseldyke,Algozzine, Regan,and Potter

A recent study challenged the ability of evaluation teams to select technically adequate data sources. Aspects of methodology and focus of inquiry restrict the interpretation of results. A more productive line of inquiry is suggested.
