Purpose of this study was to determine whether auditory perception, visual perception or chronological age is a better predictor of the control of nonverbal behavior by means of verbal instructions. (Author)

The data indicate a negative relationship between illusion susceptibility and education. This supports the sophistication hypothesis suggested by Segall, Campbell, and Herskovits. (DB)

Describes the development and testing of a new facial meaning sensitivity test designed to determine how specialized are the meanings that can be decoded from facial expressions. Demonstrates the use of the test to measure a receiver's current level of skill in decoding facial expressions. (JMF)

This study, with 93 third grade poor readers, 54 fifth grade poor readers (with and without reading/IQ discrepancies), and 147 nondisabled first graders, found poor readers significantly more impaired than the matched first graders on all measures of nonword reading thus supporting the hypothesis of a deficit in nonword reading skills not…

Two experiments evaluated the social interactions of 15 Asperger-type autistic subjects with either normal or schizoid control subjects. Asperger subjects tended to avoid gazing at the interviewer when the interviewer was talking. Results suggest that a lifelong absence of gaze response to social clues including speech may explain some features of…

The study of genotype-environment interaction (G x E) has been dominated by two competing hypotheses, one that heritability is greater in high-risk environments (diathesis-stress) and the other that heritability is greater in permissive environments. The current study examined relationships between verbal and nonverbal abilities and 10 measured…

Background: Children with speech difficulties may have associated educational problems. This paper reports a study examining the educational attainment of children at Key Stage 1 of the National Curriculum who had previously been identified with a speech difficulty. Aims: (1) To examine the educational attainment at Key Stage 1 of children…

The prefrontal cortex modulates executive control processes and structurally matures throughout adolescence. Consistent with these events, prefrontal functions that demand high levels of executive control may mature later than those that require working memory but decreased control. To test this hypothesis, adolescents (9 to 20 years old)…

Self-concept ratings of children with mathematics disabilities (MD), average mathematics achievement (AA), and high mathematics achievement (HA) who attended regular classes in grades 4 through 6 were compared. Twenty-four children in each group, who were selected from an original pool of 811 children, and who were matched one-to-one by grade,…

This study of 4-year-old twins investigated the genetic and environmental origins of comorbidity between language impairment and nonverbal ability by testing the extent to which language impairment in one twin predicted nonverbal ability in the co-twin. Impairment of language ability was defined as scores below the 15th percentile on a general…

Given the paucity of research describing the use of the TONI-3 with urban children with disabilities, a brief review of the literature was conducted. While little relevant research was identified, the use of the TONI-3 was supported in a number of diverse settings. This paper also describes a study designed to examine the validity of the Test of…

The purpose of this study was to compare the effectiveness of the Raven's Standard Progressive Matrices, the Naglieri Nonverbal Abilities Test (NNAT), and the Iowa Test of Basic Skills (ITBS) in selecting for ethnically diverse students who may be gifted. The participants of the study were 175 students enrolled in Grades 3-5 and Grade 8 in a…

Vicarious influence on emotional response has been demonstrated in several studies, but the identity between the response of the model and that of the observer has received little attention. Seventy-two children from three grade levels were tested for their ability to recognize and form facial expressions of emotion. The subjects then observed a…

This book examines recent theory and research concerning nonverbal experience and behavior and provides examples of the nonverbal experience in contemporary social expression (music, cartoons, fashion, etc.). Chapters include discussions of senses, biorhythms, body image, nonverbal messages from others, environmental factors in nonverbal…
