ASSOCIATION STRUCTURES OF MENTAL RETARDATES

Free word associations of low level retardates (I.Q., 48) and higher level (I.Q., 67) retardates were examined for evidence of normal adult word association structures (idiodynamic associative sets). Such structures were found in both groups. The low level group, however, evidenced a factor structure different from that typical of normal adults. From a semantic point of view, associations of the low level group were more “concrete” than those of the higher level group. From a syntactic point of view, the lower level group lagged well behind the higher level group on the so-called “syntactic-paradigmatic” shift.     

THE DEVELOPMENT OF NONMETRIC SPACE ANALYSIS: A LETTER TO PROFESSOR JOHN ROSS

A series of recent studies (Cliff, 1968, 1969; Cliff, Bradley, and Girard, 1970) describe a mathematical model for the cognitive processes involved in an individual's endorsements (or nonendorsements) of personality inventory items. In this model, the inventory items are assumed to occupy positions in a multidimensional space of subjective meaning, and the probability of endorsement is assumed to be some mathematical funotion of these positions.     

Development of views of life scale

Abstract

The Views of Life Scale (VOLS) was designed to measure perception of well-being in three areas: inherent value of life, effective life management, and sense of health. Items were placed in these three categories by a team of advanced doctoral students; their overall agreement on item placement was 91.8%. These three categories became Subscales I, II and III of the total instrument. Seven hundred and thirty-two participants responded to the 42 item VOLS; subsamples of this group also took various other instruments with which the VOLS was being compared. Reliability assessment yielded very strong test-retest stability (I=0.80, II=0.87, III=0.76, Total=0.86) and high internal consistency (I=0.76, II=0.83, III=0.81, Total=0.91) for the VOLS measures. Relationships between the VOLS and other inventories provided consistent support for the convergent and divergent validity of the VOLS. An oblique rotation factor analysis produced five major quantitative clusters in the VOLS. There was considerable overlap between these factors and the original subscales.     

General analytical solution for stress intensity factor of a hypocycloid hole with many cusps in an infinite plate

In this article, the problem for the determination of the displacement functions and the stress intensity factors (SIFs) around a boundary of a hypocycloid hole with cusps in an infinite elastic plate subject to normal and shear stresses are presented. A hole with cusps (hypocycloid) is mapped onto a unit circle and the modified complex potential is used for solving the relevant boundary value problems. An analytical solution for the SIF of a hypocycloid hole is obtained. For a special case, our results agree with others.     

The Relation Between Executive Function and Theory of Mind is More Than Skin Deep

A simple “expression” account of the relation between executive function (EF) and children's developing theory of mind (ToM) has difficulty accounting for the generality of the changes occurring in children's mental-state understanding during the preschool years. The current study of preschool children (N = 43) showed that EF—especially conflict EF—related uniformly to ToM measures that imposed either high or low executive demands, independent of verbal ability. These findings can be explained within an emergence account wherein executive skills are implicated in the acquisition of mental-state concepts as opposed to merely the expression of these concepts in task performance.     

The Relation of Parent and Child Gender to Parental Tolerance of Child Disruptive Behaviors

Parental tolerance has been defined as the degree to which a parent tends to be annoyed by his or her child’s disruptive behavior. The purpose of the current study is to examine the relation of both parent and child gender to parental tolerance of child disruptive behaviors. Participants were 150 parents with 3–6 year-old at-risk children (47.5 % girls) who sought help with parenting of their child’s oppositional defiant behaviors. Tolerance was measured by the difference between parent ratings of intensity on 36 disruptive behaviors and whether each behavior was identified as a problem (resulting in a score of either high, expected, or low tolerance). A 2 (child gender) by 2 (parent gender) analysis of variance was conducted on the tolerance score. A significant interaction between child and parent gender emerged: Mothers were equally tolerant of boys’ and girls’ oppositional defiant behavior but fathers were more tolerant of boys’ than girls’ oppositional behavior. Exploratory analyses suggested that this interaction may be qualified by clinical status of the child. Implications and future directions are discussed.     

The Role of Contextual Threat in Predicting Self-Reported Distress among Siblings of Children with Cancer

Each year, 14,000 children are diagnosed with cancer in the United States. Prolonged, intensive treatment regimens disrupt the entire family system, but effects on siblings are poorly understood. In this preliminary investigation, we employed a risk and resistance framework to study adjustment among 30 siblings (aged 10–17) of children undergoing cancer treatment. We examined whether or not objective stress associated with the cancer experience (contextual threat) predicted sibling distress and explored demographic and disease-related predictors of sibling adjustment. Contextual threat was positively associated with sibling-reported distress, independent of sibling age, gender, birth order relative to the child with cancer, and cancer treatment intensity. From among the demographic and disease-related factors, only younger birth order relative to the child with cancer was independently associated with sibling distress. These results suggest that a subset of siblings may be at increased risk for elevated distress in the face of their brother’s or sister’s illness.     

Masculinity and Self‐Esteem in Israeli Jewish Professional Women 1

The literature suggests that while women experience unique challenges with self‐esteem and self‐acceptance, Jewish professional women in Israel face additional challenges in balancing majority culture values, ethnic traditions, and the socio‐historical‐political context of the country. The present study investigated differences in masculinity, femininity, locus of control, self‐esteem, and self‐acceptance among Israeli Jewish and other professional women, including professional women scientists. Masculinity scores were significantly lower for Israeli Jewish women, and self‐acceptance scores were significantly lower for Israeli Jewish women than for the group of professional women.     

The Irony of Measurement by Subjective Estimations

In 1948 S. S. Stevens, in his famous Science article, proposed a theory of measurement that radically differed from the dominate theory of the time. The dominate theory held that all strong forms of scientific measurement— for example, those that yielded ratio scales—had to be based on an observable ordering and an observable commutative and associative operation. Stevens proposed different criteria and introduced his method of magnitude estimation. Stevens as well as measurement theorists considered his method to be radically different from those based on commutative and associative operations. Although his method was controversial, it became a standard tool in the behavioral sciences. This article argues that Stevens' method, together with implicit assumptions he made about the scales of measurement it generated, is from a mathematical perspective the same as the measurement process based on commutative and associative operations. The article also provides a theory of qualitative numbers and shows an interesting relationship between qualitative numbers and Stevens' method.
