The article describes current research on stereotypes in a group of blind children in Barcelona, Spain. Mannerisms and blindisms covering a range of verbal and motor behavior are defined and discussed, as are the variables of behavior related to them. (Author/DB)

The relationship between preferred objects associated with stereotypy, stereotypic behavior, and accuracy of responding during a counting task by a child with autism was analyzed. Teaching with high-preference objects occasioned more stereotypic behavior and less accurate counting than teaching with medium- and low-preference objects. (Author/DB)

Examines the relations of Type A scores of parents to Type A scores of their children. Parent-child correlations were found for father-son pairs. (PCB)

This study assessed the validity of idiosyncratic choice-making behaviors of three children with multiple disabilities. Children were given either their "choice" of food or drink or were given the opposite. Direct observations of children's acceptance or refusal revealed the children consistently indicated choices during both conditions.…

An investigation was conducted of the displayed biobehavioral states of 5 students (ages 8-20) with profound mental retardation. Results indicated that state level can be reliably specified and that overall state characteristics can be used to classify subjects according to profile groups. (Author/JDD)

This study compared the occurrence and characteristics of self-stimulatory behaviors of 5 children with developmental delays and 10 nondisabled children (matched for either mental or chronological age). Few differences were found between groups in percentage of time spent in self-stimulatory behavior, the variety of such behaviors, the speed at…

The relationship between abnormal stereotyped behaviors and abnormal focused affections was examined in 20 children (ages 7-13) with developmental disabilities. Results include all children with abnormal focused affections exhibited stereotypes; abnormal focused affects could be studied reliably in this population through several methodologies;…

Mentally retarded emotionally disturbed children (N=31) were compared on the Child Depression Inventory and the Child Behavior Profile with 31 children in a normal school setting. Correlational data showed a strong relationship between the cut-off scores for both measures suggesting that similarities exist between depression in mentally retarded…

This study compared the effects of unequal and equal reinforcer duration during a functional analysis of aberrant behavior in an 11-year old with moderate mental retardation. Results showed that reinforcer duration affects the rate of aberrant behavior and may potentially alter functional analysis interpretation. (DB)

Cognitive and behavioral effects of temporarily elevating levels of phenylalanine in treated phenylketonuria (PKU) were investigated in a triple-blind crossover study with 16 early and continuously treated children and adolescents with PKU. Results suggest that intellectual ability, memory, and conduct are not affected by medium-term elevated…

An ecological method was used to assess the patterns of goal-directed behaviors of eight children with autism and eight chronological and mental age comparable children with Down syndrome. Analysis of quantitative and qualitative behavior coding indicated that children with autism exhibited shorter and less overlapping goal-directed behaviors,…

The follow-up study examined 16 schizo-affective children after a mean of 16 years. In comparison to purely schizophrenic controls, subjects showed an increased incidence of affective psychoses, suicide in the ancestry, and more pre-morbidly well-adjusted personalities. The schizo-affective psychoses had mainly an acute-recurrent character.…

Two case examples (a toddler with severe developmental delays and a 7-year old with severe mental retardation) illustrating effects of meal schedule and food quantity on displays of problematic behavior are offered. Brief functional analyses of aberrant behavior provided useful information for interpreting distinct patterns of behavior. (DB)

The effectiveness of fenfluramine with hyperserotonergic autistic individuals (n=28 and ages 6-30) was evaluated. Evaluation of videotape recordings of individual behaviors suggested that fenfluramine failed to increase communicative behaviors or decrease stereotypic behaviors and inappropriate behaviors although a serotonergic effect was found in…

Self-injurious behavior was examined in a case study of head-banging by an 8-year-old girl with profound mental retardation and an autistic disorder. Trajectories of arm movements and impact forces were determined from dynamic analysis of videotapes. Cycle-to-cycle consistency in the qualitative dynamics of the limb motions and impact forces…
