Sensorimotor skills and language comprehension in autistic children

The objectives of this study were to examine the level of sensorimotor concepts of young autistic children and to relate these concepts to language comprehension. A sample of 16 autistic children with a mean mental age of 24.8 months was administered a standardized scale of sensorimotor intelligence and of receptive language. The autistic children demonstrated surprisingly sophisticated sensorimotor skills, particularly object permanence. While their initial performance was inferior to that of normal controls matched on mental age, particularly in their use of objects in combination, the difference between groups diminished on the second test administration. On the receptive language measure, the autistic children were less able to identify words correctly. The sensorimotor behavior of autistic children who demonstrated language comprehension did not differ from those who showed no language comprehension, except that the former group tended to use an object as an instrument somewhat more frequently. The fact that the autistic children were so impaired in language even with fairly good sensorimotor skills suggests that these skills, particularly object permanence, play a minor role in their language acquisition.Support for this research was provided by Biobehavioral Research Support Grant 516, Grant 12–41 from the March of Dimes, NIMH Postdoctoral Fellowship No. 1 F32 MH07550-01 (Ungerer), and NIMH Grant MH 33815-01. Subjects were recruited from the UCLA Research Center for the Study of Childhood Psychosis, funded by NIMH Grant MH 30897.

Training and practice of school psychologists in reading assessment and intervention

A national sample of school psychologists was randomly surveyed to assess (1) training practices in reading assessment and intervention, (2) their involvement with reading-disabled students, (3) the degree of importance they place on knowledge of assessment and remediation of reading problems, and (4) their perceptions of their expertise in these latter areas. The results revealed major discrepancies between preparation and job responsibilities. The respondents indicated (1) that they had received limited training in reading, (2) that 77% of referrals involved reading problems, (3) that they frequently made reading recommendations, but felt they lacked adequate expertise, and (4) that they supported the need for more expertise in reading. The implications for training and practice are discussed.     

Experimental manipulation of infant temperament affects amygdala functional connectivity

In this functional magnetic resonance imaging (fMRI) study we examined neural processing of infant faces associated with a happy or a sad temperament in nulliparous women. We experimentally manipulated adult perception of infant temperament in a probabilistic learning task. In this task, participants learned about an infant's temperament through repeated pairing of the infant face with positive or negative facial expressions and vocalizations. At the end of the task, participants were able to differentiate between “mostly sad” infants who cried often and “mostly happy” infants who laughed often. Afterwards, brain responses to neutral faces of infants with a happy or a sad temperament were measured with fMRI and compared to brain responses to neutral infants with no temperament association. Our findings show that a brief experimental manipulation of temperament can change brain responses to infant signals. We found increased amygdala connectivity with frontal regions and the visual cortex, including the occipital fusiform gyrus, during the perception of infants with a happy temperament. In addition, amygdala connectivity was positively related to the post-manipulation ratings of infant temperament, indicating that amygdala connectivity is involved in the encoding of the rewarding value of an infant with a happy temperament.     

WOMEN'S INTENTIONS REGARDING, AND ACCEPTANCE OF, SELF-SEXUALIZING BEHAVIOR

No known research has examined women's acceptance of self-sexualizing behaviors, which includes the use of catwalks at dance clubs, taking pole dance classes, and wearing clothing with sexually suggestive statements. Structural equation modeling assessed the links between choosing sexually objectifying media, internalized appearance ideals, and self-objectification to self-sexualizing behaviors and general acceptance of sexualizing behavior among 207 female university students. Media choice predicted one's own behavioral intentions and the acceptance of others' sexualizing behavior. Neither internalized appearance ideals nor self-objectification mediated these relations. Hyperfemininity and sexism were tested as individual difference variables predicting these variables. Hyperfemininity added to the prediction of self-sexualizing behaviors and general acceptance of sexualizing behavior, whereas sexism did not. Our results indicate that sociocultural ideals of women's sexual attractiveness predict women's intentions regarding, and acceptance of, sexualizing behavior. Self-sexualizing behavior may have negative consequences, including the lack of subjective experience of one's sexuality.     

Providing Ongoing Skill Development and Support for Educators and Parents of Students with Emotional and Behavioral Disabilities

Target six of the national agenda to improve outcomes for students with or at risk of emotional disturbance is reviewed. Having discussed this target with multiple stakeholders, the authors present four underlying themes that support ongoing skill development of providers and parents alike. These include building capacity of providers, decreasing isolation of school staff, gaining commitment of all school staff to support students with challenging behavior, and including parents and family members in staff development activities. The four underlying themes are discussed and recommendations given for ensuring ongoing skill development and support in education.     

Serial reaction time performance following right parietal lobe damage

The serial reaction time task (SRT) is used to assess implicit sequence learning. Neuroimaging studies implicate parietal involvement; however, the necessity of this area is unclear. We tested six unilateral right parietal patients and compared their performance to matched controls. Both groups showed similar levels of learning and explicit awareness. Two patients with the largest lesions extending into either frontal or cerebellar regions showed no learning. These data suggest that implicit sequence learning can occur despite damage to the right parietal lobe.     

Modeling longitudinal change in the language abilities of children with autism: parent behaviors and child characteristics as predictors of change

The objective of the current study was to evaluate the patterns of longitudinal change in the language abilities of 28 children with autism during early and middle childhood. Results from fitting a series of multilevel models showed that children's rate of language growth was independently predicted by (a) children's responsiveness to others' bids for joint attention and (b) parents' responsiveness to their children's attention and activity during play. Both predictive relations could not be explained by initial variation in global developmental characteristics, such as IQ, mental age, or language abilities. These findings support a social?pragmatic view on language acquisition, which emphasizes the collaborative process through which children and their parents negotiate shared meaning.
