Children's Awareness of Peer Rejection and Teacher Reports of Aggressive Behavior / La percepción del niño del rechazo de sus compañeros y el comportamiento agresivo según los docentes

Lack of awareness of one's negative social reputation is linked to aggressive behavior among older school-age children. The present study extends this research to the first year of elementary school. The first goal was to compare generalized and dyadic perspectives in studying discrepancies between children's actual and perceived rejection. The second goal was to determine whether discrepancies between actual and perceived rejection are related to sociometric status. The third goal was to examine whether discrepancies between actual and perceived rejection are related to aggressive behaviors at school. Actual peer rejection was measured with peer negative nominations, perceived peer rejection with students' self-ratings and meta-perceptions, and aggressive behavior with teacher ratings. The discrepancies between actual and self-perceived rejection were substantial in the total sample. Furthermore, non-rejected children had higher scores than rejected children in dyadic overestimation (identifying peers who they believed disliked them but did not), while it was the reverse for dyadic underestimation (not identifying peers who in fact disliked them). High levels of dyadic underestimation were negatively associated with the concurrent aggressive behavior. Rejected children's underestimation of their peer rejection appeared to have protective effects on antisocial and aggressive problems. Findings are discussed in terms of theories of symbolic interactionism and social information processing

No ser consciente de la mala reputación propia está relacionado con el comportamiento agresivo de niños y niñas. El presente trabajo amplia la investigación al inicio de la escuela primaria. El primer objetivo fue comparar la percepción generalizada y diádica en la discrepancia entre el rechazo real y el percibido. El segundo objetivo fue determinar si la discrepancia entre rechazo real y percibido está relacionada con el tipo sociométrico. El tercer objetivo fue examinar si la discrepancia entre rechazo real y percibido está relacionada con conductas agresivas. El rechazo real se midió con nominaciones negativas, el rechazo percibido con autoinformes y el comportamiento agresivo con calificaciones de los docentes. La discrepancia entre rechazo real y autopercibido fue sustancial en la muestra total. Además, los niños y niñas no rechazados obtuvieron puntajes más altos que los rechazados en la sobreestimación diádica (identificar como rechazadores a compañeros que de hecho no les rechazaron), mientras se dio la pauta inversa en la subestimación diádica (no identificar como rechazadores a compañeros que sí rechazaron al niño o a la niña). Los niveles elevados de subestimación diádica se asociaron negativamente con el comportamiento agresivo. La subestimación de los niños o niñas rechazados parece tener efectos protectores sobre los problemas antisociales/agresivos. Se comentan los hallazgos en relación con la teoría del interaccionismo simbólico y el procesamiento de la información social

A systematic review on 'Foveal Crowding' in visually impaired children and perceptual learning as a method to reduce Crowding.

BACKGROUND: This systematic review gives an overview of foveal crowding (the inability to recognize objects due to surrounding nearby contours in foveal vision) and possible interventions. Foveal crowding can have a major effect on reading rate and deciphering small pieces of information from busy visual scenes. Three specific groups experience more foveal crowding than adults with normal vision (NV): 1) children with NV, 2) visually impaired (VI) children and adults and 3) children with cerebral visual impairment (CVI). The extent and magnitude of foveal crowding as well as interventions aimed at reducing crowding were investigated in this review. The twofold goal of this review is : [A] to compare foveal crowding in children with NV, VI children and adults and CVI children and [B] to compare interventions to reduce crowding. METHODS: Three electronic databases were used to conduct the literature search: PubMed, PsycINFO (Ovid), and Cochrane. Additional studies were identified by contacting experts. Search terms included visual perception, contour interaction, crowding, crowded, and contour interactions. RESULTS: Children with normal vision show an extent of contour interaction over an area 1.5-3× as large as that seen in adults NV. The magnitude of contour interaction normally ranges between 1-2 lines on an acuity chart and this magnitude is even larger when stimuli are arranged in a circular configuration. Adults with congenital nystagmus (CN) show interaction areas that are 2× larger than those seen adults with NV. The magnitude of the crowding effect is also 2× as large in individuals with CN as in individuals with NV. Finally, children with CVI experience a magnitude of the crowding effect that is 3× the size of that experienced by adults with NV. CONCLUSIONS: The methodological heterogeneity, the diversity in paradigms used to measure crowding, made it impossible to conduct a meta-analysis. This is the first systematic review to compare crowding ratios and it shows that charts with 50% interoptotype spacing were most sensitive to capture crowding effects. The groups that showed the largest crowding effects were individuals with CN, VI adults with central scotomas and children with CVI. Perceptual Learning seems to be a promising technique to reduce excessive foveal crowding effects.
