Contemporaneous and Longitudinal Associations of Sibling Conflict with Family Relationship Assessments and Family Discussions about Sibling Problems

The first purpose of this study was to examine contemporaneous and longitudinal associations of maternal and paternal measures of family functioning with observational and self-report assessments of sibling conflict. The second purpose was to determine whether the ways in which families attempt to solve siblings' problems are associated with contemporaneous and longitudinal assessment of sibling conflict. The results indicate that paternal equality of treatment and family harmony during family discussions about sibling problems, as well as parents' perceptions of family cohesiveness, are associated with lower sibling conflict levels.     

Pathways to literacy: a study of invented spelling and its role in learning to read

This intervention study tested whether invented spelling plays a causal role in learning to read. Three groups of kindergarten children (mean age = 5 years 7 months) participated in a 4-week intervention. Children in the invented-spelling group spelled words as best they could and received developmentally appropriate feedback. Children in the 2 comparison groups were trained in phonological awareness or drew pictures. Invented-spelling training benefited phonological and orthographic awareness and reading of words used in the intervention. Importantly, the invented-spelling group learned to read more words in a learn-to-read task than the other groups. The finding are in accord with the view that invented spelling coupled with feedback encourages an analytical approach and facilitates the integration of phonological and orthographic knowledge, hence facilitating the acquisition of reading.     

Parent-Child Relationships, Family Problem-Solving Behavior, and Sibling Relationship Quality: The Moderating Role of Sibling Temperaments

In this study we sought to determine whether sibling temperaments moderated the associations of parent-child relationship quality and family problem-solving behavior with sibling relationship quality. Observational assessments of mother-child and father-child relationship quality, family problem-solving behavior, and sibling relationship quality were obtained from the families of 49 pairs of brothers and 46 pairs of sisters. Mean ages were 10-2 for older siblings and 7-6 for younger siblings. Parent-reported child temperament assessments were also obtained. The links among mother–older child relationship quality, father–older child relationship quality, and sibling relationship quality were moderated by the older sibling's temperament. The younger and older siblings' temperaments moderated the associations between the quality of the father–younger sibling and sibling relationships. The association between family problem-solving behavior and sibling relationship quality was not moderated by sibling temperaments.     

The empirical derivation of equations for predicting subjective textual information

Parameters pertaining to information processing by human beings have, in the past, been determined by learning and memory experiments with nonsense syllables, number sequences, etc. However, in the real world we are concerned with the processing of meaningful information, not senselles texts. Therefore, the determination of subjective information directly from meaningful material becomes extremely important in the instruction-learning process.This study derives an equation for predicting the subjective textual information contained in a text of material written in the English language. Specifically, this investigation describes, by a mathematical equation, the relationship between the subjective information content of written textual material and the relative number of errors committed by a learner when asked to predict, letter by letter, the content of given textual material. This relationship shows that the subjective information of a given text for a specific learner is directly proportional to the number of wrongly guessed signs made by that learner. This is expressed mathematically by% MathType!MTEF!2!1!+- % feaafeart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn % hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr % 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9 % vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x % fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamysaiabg2 % da9iaaiodacaGGUaGaaGymaiaabccacaWGfbaaaa!3B57! \[ I = 3.1{\rm{ }}E \] 0935 0212 VWhere: I = Information in bits E = Number of wrongly guessed signsThe application of Shannon's guessing procedure (1951) in this study permits the measurement of the subjective information of a given text for a specific learner. Unlike senseless texts, the subjective information of a meaningful text varies from learner to learner. Therefore, the derived equation permits the measurement of information in terms of a value that is dependent not only upon the inherent qualities of the subject matter, but also upon the internal state of the learner.The derived equation for the English language is then compared to an equation derived by Weltner (1967) for the German language and found to be remarkably similar.This work was, in part, supported by United States Air Force Contract F41609-71-C-0027 entitled Flying Training Research on Airborne and Ground Training Systems, and a research grant from Arizona State University.     

Sibling Temperaments, Conflict, Warmth, and Role Asymmetry

The association between sibling temperament combinations (activity and adaptability) and qualitative aspects of the sibling relationship were examined, including in-home observations of sibling positivity/warmth, negativity/conflict, social engagement, and role asymmetry and older sibling perceptions of warmth/closeness, conflict, and status/power. The sample consisted of 67 same-gender, school-aged sibling pairs. Highest levels of negativity/conflict occurred when both siblings were high in activity and when the older sibling was rated as more active than the younger. Conflict was lowest when both siblings were low in activity. Warmth/positivity was greatest when both children were similar in activity level. Siblings were more socially engaged when the the older sibling was more adaptable than the younger. Perceived status/power was greatest when younger siblings were low in adaptability. When between-temperament-dimension relationships were examined, observed conflict was greatest when older siblings were high in activity and younger siblings were nonadaptable. Gender and age-related findings are also reported. Findings highlight the importance of identifying the complex ways in which varying dimensions of sibling temperaments combine to influence specific aspects of the sibling relationship.
