Phonological representation and speech understanding with cochlear implants in deafened adults

In the present study cognitive performance in 15 deafened adult cochlear implant candidates was examined and related to level of speech understanding after 12 months of experience with the implant. The implant group performed on par with normal hearing controls in all cognitive tasks used in the study with one exception: Performance was significantly lower in cognitive tasks where use of a phonological representation of sound is a key task-demand. Observations of the implanted individuals’ level of speech understanding indicate that only those individuals who, pre-operatively, were in possession of phonological representations comparable to that of normal hearing could follow and understand a speaker that was out of sight. The results are discussed with respect to (a) deterioration in the phonological representation of sounds as a function of absence of external auditory stimulation, and (b) the role of cognitive factors in predicting success in speech understanding with the implant.     

Caregiver interactions with autistic children

Caregiver interactions with young autistic children were contrasted with those involving caregivers and developmentally matched mentally retarded and normal infants. Caregivers of autistic children were similar to other caregivers in their responsiveness to child nonverbal communication bids and in their engagement in mutually sustained play. Caregivers of autistic children were similar to caregivers of mentally retarded children in their greater use of control strategies. However, these two groups of caregivers differed in the particular strategies they used to shape their children's behavior. Caregivers of mentally retarded children pointed to objects while caregivers of autistic children spent more time physically holding their children on task. Individual differences within the autistic sample indicated that caregivers regulated their children's behavior less and showed more mutual play and positive feedback to more communicatively able autistic children. These findings suggest that caregivers respond differentially to the specific deficiencies shown by their children.     

Unique sets of social and mood characteristics differentiate autistic and negative schizotypy traits in a young adult non-clinical sample

While well-established as distinct disorders, new evidence linking autism and schizophrenia has emerged. One line of evidence is the strong correlation identified between the social traits assessed by the Autism Spectrum Quotient (AQ:Social) and the negative traits of schizotypy. To further explore this association, the current study examined whether these sets of traits are convergent or divergent in the degree to which they relate to specific aspects of socio-emotional functioning. Regression analyses conducted on self-report data collected from 284 undergraduate students showed that the social items from the AQ uniquely relate to levels of social anxiety and social skills, while negative schizotypy traits uniquely relate to social anhedonia and depression. Additionally, AQ:Social and negative schizotypy traits were found to share a significant proportion of variance, independent of each of the socio-emotional variables examined. The results thus provide further evidence of shared atypical social function linked to both autistic-like traits and negative schizotypy traits, but importantly also highlight clear differences in the specific socio-emotional profiles associated with these sets of traits.     

Infant-parent psychotherapy with an autistic toddler

This paper describes the 3½ -year treatment of an autistic toddler, who by age 5 showed normal social relationships and only minor residual cognitive features of the disorder. The treatment approach integrated infant-parent psychotherapy with techniques of special education and involved a two-person team that worked simultaneously in the family's home. The early work focused on discovering ways to mediate environmental stimulation so as to enhance the child's availability for social interaction. The treatment helped the parents understand this and explored and interpreted misconceptions about their son that interfered with parental feelings and functions. Multiple issues in the parent-child relationship and in the child's social and cognitive development eventually were addressed. This case illustrates one scenario in the development of relationships when an infant lacks the biological fittedness for social interaction. It demonstrates the possibility of ameliorating the autistic condition through a modification of infant-parent psychotherapy. The successful outcome of the case seems to be the result of several factors: The child's age at the beginning of treatment, his areas of cognitive strength, and his parents' exceptional ability to use and extend the therapy.     

Pitch perception in children with autistic spectrum disorders

This study investigated the accuracy of musical pitch detection in children with autistic spectrum disorders as compared with typically developing children. Seventeen children on the autistic spectrum (M(age) =9.34, SD(age) =1.12) and 13 typically developing, chronological age-matched children (M(age) =9.13, SD(age) =1.68) took part in the current study. Children were required to listen to four tones, which were paired with four different pictures and asked to learn the combinations. The children were then assessed for their ability to identify the previously learned tones, when they were presented as single tones and when they were embedded in chords and discords. No significant group differences were found. However, after subdividing the clinical group according to their diagnosis of autism or Asperger's syndrome, the results indicated a slightly superior disembedding ability in participants with Asperger's syndrome. The findings are discussed in terms of the weak central coherence concept.     

Measuring change in psychotherapeutic work with a traumatised child on the autistic spectrum

This paper describes a developmental psychotherapy undertaken with a physically disabled latency boy, with a background of significant developmental deficits and multiple psychological trauma, diagnosed by CAMHS as being on the autistic spectrum. Using an assessment framework following Anna Freud’s conceptualisation of developmental lines, pathology as a deviation from the norm was formulated. Assessments using standard psychological tests were made at the beginning, in the middle, and at the end of his therapy, in order to study the changes in his personality development. Standard assessment findings were also used to portray the fragmentation of the boy’s psyche in a concrete fashion, in order to facilitate his re-integration.     

Unfamiliar face recognition in children with autistic spectrum disorders

We investigated unfamiliar face recognition in low‐functioning children with autistic spectrum disorders (ASD) using a ‘part‐of‐face’ method. This method has not previously been used for unfamiliar faces with this population. The ‘part‐of‐face’ procedure provides measures of both face recognition accuracy and of processing style. We compared the performance of the children with ASD with three control groups: children with developmental delay (DD), typically developing (TD) children matched for verbal cognitive ability and TD children matched for chronological age (CA). Compared to the DD group, the ASD group showed similar processing in recognition accuracy and processing style. Compared to the TD children, the ASD group did not show the same level of accuracy as controls of the same CA, instead showing similar performance to younger TD children. However, as both children with ASD and DD showed the same performance, no ASD‐specific deficit was found. Copyright © 2009 John Wiley & Sons, Ltd.     

Treatment effects of a total behavior modification program with five autistic children

Five autistic children were studied intensively to devise effective treatment procedures with the goal of eventual return to their homes. An experimental-clinical approach was used to design behavior modification programs specifically for each child. All children made varying degrees of progress, but thier learning deficits continued to interfere with learning all new responses, necessitating continuation of a structured home or institutional existence to maintain the treatment gains. Retardation remained a characteristic of all children, retrieval of previously decelerated referral behaviors was problematic at date of discharge, and response acquisition did not appreciably facilitate learning of more complex behavior on the same response hierarchy.     

Stress in mothers of individuals with autistic spectrum disorders

The aim of this study was to analyze maternal stress in families of individuals with autism. We proposed a multi-factorial and global model based on the Double ABCX model of family stress (McCubbin & Patterson, 1983) in which, the factor aA (stressor) interacts with bB (social support) and cC (perception of stress or, in our study, sense of coherence, SOC) to produce the dependent factor xX (level of stress). Thirty-nine mothers with children diagnosed on Autistic Spectrum disorders completed four questionnaires relating to the factors. The data were statistically analyzed using path analysis. The results showed that the empirical data fitted the theoretically proposed model well. There existed a direct and positive relationship between stressor and stress. Social support and SOC had a direct and negative relationship to stress, and functioned as modulating variables.     

Babytalk as a communication of intimate attachment: An initial study in adult romances and friendships

Babytalk is a speech register that has been studied most extensively as it is spoken by mothers to infants, but without attention to its possible role in emotional bonding. We suggest that babytalk plays such a role–that it expresses and facilitates intimate psychological connection, and in a variety of relationships. We first overview relevant literature to show that an association between babytalk and intimate attachment makes sense. Then we report a questionnaire study, which is the first to explore this association as well as the first empirical documentation that babytalk occurs in adult romances and friendships. Self-reported features and examples of the speech register (as spoken in a particular romance) verified it as babytalk. Individuals who had babytalked to friends or romantic partners tended to be more secure and less avoidant with regard to attachments in general. Within a particular romantic relationship, indicators of intimacy and attachment accounted for about 22% of the variance in babytalk frequency. Partner's babytalking was the strongest predictor, accounting for about 42% of the variance. Communication intentions accompanying babytalk paralleled the hallmarks of attachment, especially affection and play. These and other results suggest that babytalk functions in the process of intimate personal connection.     

Visual perspective taking impairment in children with autistic spectrum disorder

Evidence from typical development and neuroimaging studies suggests that level 2 visual perspective taking - the knowledge that different people may see the same thing differently at the same time - is a mentalising task. Thus, we would expect children with autism, who fail typical mentalising tasks like false belief, to perform poorly on level 2 visual perspective taking as well. However, prior data on this issue are inconclusive. We re-examined this question, testing a group of 23 young autistic children, aged around 8 years with a verbal mental age of around 4 years and three groups of typical children (n = 60) ranging in age from 4 to 8 years on a level 2 visual perspective task and a closely matched mental rotation task. The results demonstrate that autistic children have difficulty with visual perspective taking compared to a task requiring mental rotation, relative to typical children. Furthermore, performance on the level 2 visual perspective taking task correlated with theory of mind performance. These findings resolve discrepancies in previous studies of visual perspective taking in autism, and demonstrate that level 2 visual perspective taking is a mentalising task.     

Auditory overselectivity in autistic children

Autistic and normal children were trained to respond to a complex stimulus containing two auditory components. After the discrimination was acquired, the individual components were presented separately, allowing assessment of the extent to which the child's responding was controlled by one or both of the cues. The autistic children, unlike the normal children, provided evidence for stimulus overselectivity in that 6 of 8 autistic subjects responded to only one of the components. These results are consistent with those of previous studies which showed that when autistic children are presented with a complex visual or multiple-modality stimulus, they selectively respond to only one component of the complex. The present results extend the stimulus overselectivity hypothesis to the situation where all of the stimuli occur within the auditory modality. It is suggested that auditory overselectivity may partially account for autistic deficits in speech comprehension.     

The autistic moment in psychotherapy

This is a report on the author's experience in treating four autistic children and their families. The importance of making available the therapist's own autism is stressed. The difficulty in doing this and reverting defensively to an administrative approach is described. A previous paper discussed the corrective autistic experience with a focus on the autistic person. This follow-up describes the autistic moment which is a relational experience between the therapist and both the autistic person and the autistic family. The family needs to have an experience of its own autism as a continuum of normal before it can relate to an autistic child. To the extent that the therapist can bring his own autism into the therapy can the family experience its own. The patients are the person, the relationships, the family, and the therapist.The author would like to thank Richard B. Anderson, MD, Lindy T. Barnett, MSW, David V.

Memory in autistic spectrum disorder

Behavioral evidence concerning memory in forms of high-functioning autism (HFA) and in moderately low-functioning autism (M-LFA) is reviewed and compared. Findings on M-LFA are sparse. However, it is provisionally concluded that memory profiles in HFA and M-LFA (relative to ability-matched controls) are similar but that declarative memory impairments are more extensive in M-LFA than in HFA. Specifically, both groups have diminished memory for emotion- or person-related stimuli. Regarding memory for nonsocial stimuli, both groups probably have mental-age-appropriate nondeclarative memory, and within declarative memory, both groups have mental-age-appropriate immediate free recall of within-span or supraspan lists of unrelated items, as well as cued recall and paired associate learning. By contrast, recognition is largely unimpaired in HFA but moderately impaired in M-LFA, and free recall of meaningful or structured stimuli is moderately impaired in HFA but more severely impaired in M-LFA. Theoretical explanations of data on declarative memory in HFA identify problems in the integrative processing, or the consolidation and storage, of complex stimuli or a specific problem of recollection. Proposed neural substrates include the following: disconnectivity of primary sensory and association areas; dysfunctions of medial prefrontal cortex, hippocampus, or posterior parietal lobe; or combinations of these associated with neural disconnectivity. Hypothetically, perirhinal dysfunction might explain the more extensive declarative memory impairments in M-LFA. Foreseeable consequences of uneven memory abilities in HFA and M-LFA are outlined, including possible effects on language and learning in M-LFA. Finally, priorities for future research are identified, highlighting the urgent need for research on memory in lower functioning individuals.     

Response restriction and substitution with autistic children.

Few studies to date have examined time reallocation in naturalistic, multiresponse human repertoires when one or more responses are restricted. For this experiment, free-operant baseline levels of six responses were measured for four autistic children. The high-probability responses were made unavailable, one at a time, such that subjects had access to five, four, three, and two responses in successive restriction conditions. A return to the six-response free-operant baseline condition completed the experiment. Results were compared to predictions made by four time-reallocation models. These results were described accurately only by the selective substitution model. Further analyses examined alternative explanations for the individual reallocation patterns obtained. An expanded selective substitution definition is proposed that may characterize orderly patterns observed in multiresponse repertoires under restriction conditions more accurately than the other existing models.
