Perception of radial distance as a function of magnification and truncation of depicted spatial layout

A 2×2 factorial design requiring judgments of interobject distance was utilized which separated the effects of magnification per se from the concomitant truncation of the visual field normally effected by optically produced magnification. Only the main effect of magnification was significant, and this was much less than the decreases optically specified by the decreased perspective and texture gradients.     

Attitudes toward the division of child-rearing responsibility

Though the theoretical and clinical ramifications of attribution of primary responsibility to mothers for child rearing have been discussed extensively, there is little empirical data in this area. In the present study a sample of parents rated several child-rearing behaviors in terms of ideal maternal and paternal responsibility. Mothers were attributed primary responsibility for the largest proportion of behaviors, fathers for the smallest, and an intermediate number of items were rated as parentally shared. In addition, item analysis indicated a relationship between the directionality of responsibility attribution and traditional sex-role stereotypes. Implications for patterns of intrafamilial blame and clinical intervention are discussed.     

The concept of boundaries in counselling and psychotherapy

Boundaries in the mind—the relative 'thinness' and 'thickness' of many kinds of boundaries—has been studied as a measurable dimension of personality. Persons scoring 'thin' overall on the Boundary Questionnaire can be described as open, trusting, vulnerable, and usually having a rich fantasy life; they are people in whom 'everything gets through'. People who score very 'thick' tend to be solid, well-organised, and sometimes rigid. The relationship of boundaries to other measures of personality, to dreams and nightmares, to clients' occupations and interests, and finally to the conduct of psychotherapists and counsellors, including the question of boundary violations, is discussed. Some boundary violators have very thin boundaries and are unable to maintain clear distinctions between the client's needs and their own; others have relatively thick boundaries which make them insensitive to the damage that boundary violations can cause. Awareness of the client's boundaries and one's own can be useful in 'matching' a client with a therapist and in the conduct of therapy, especially at stressful times. It is also useful at times to discuss boundaries with clients.     

Ontology, Understanding, and the A Priori

How might one explain the reliability of one's a priori beliefs? What if anything is implied about the ontology of a certain realm of knowledge by the possibility of explaining one's reliability about that realm? Very little, or so it is argued here.     

Is Isaac without Ishmael complete? A nineteenth‐century debate re‐visited

Biblical passages which Christians have traditionally applied to Islam, predicting the rise of false prophets and of false Christs, inform negative judgements. The theory of one nineteenth‐century writer, Charles Forster (1787–1871) is examined as possibly offering a sympathetic Biblical‐key in its interpretation of God's promise to Abraham that he would bless Ishmael and make him father of a great nation. Islam, Forster argued, fulfilled this promise: permitted to exist by God, Islam's eventual “bringing in” to the Kingdom would be by divine not human action. This raises questions about the propriety of proselytizing Muslims and suggests that theological disputation might yield to mutual striving to “do good works” or to obey God's will (Q.5:48; Matt 7:21).     

Cognitive correlates of mathematical achievement in children with cerebral palsy and typically developing children

Background . Remarkably few studies have investigated the nature and origin of learning difficulties in children with cerebral palsy (CP). Aims . To investigate math achievement in terms of word‐problem solving ability in children with CP and controls. Because of the potential importance of reading for word‐problem solving, we investigated reading as well. Sample . Children with CP attending either special (n= 41) or mainstream schools (n= 16) and a control group of typically developing children in mainstream schools (n= 16). Method . Group differences in third grade math and reading, controlled for IQ, were tested with analyses of co‐variance (ANCOVAs). Hierarchical regression was used to investigate cognitive correlates of third grade math and reading. Predictors included verbal and non‐verbal IQ measured in first grade, components of working memory (WM) and executive function (EF) measured in second grade, and arithmetic fact fluency and reading measured in third grade. Results . Children with CP in special schools performed significantly worse than their peers on word‐problem solving and reading. There was a trend towards worse performance in children with CP in mainstream schools compared to typically developing children. Conclusions . Impairments of non‐verbal IQ and WM updating predicted future difficulties in both word‐problem solving and reading. Impairments of visuospatial sketchpad and inhibition predicted future word‐problem, but not reading difficulty. Conversely, deficits of phonological loop predicted reading but not word‐problem difficulty. Concurrent arithmetic fact fluency and reading ability were both important for word‐problem solving ability. These results could potentially help to predict which children are likely to develop specific learning difficulties, facilitating early intervention.
