“…The correlation between the extents of hand stereotypies and adult attention was insignificant and there were no consistent associations between hand stereotypies and adult attention revealed in the concurrent or sequential lag analyses. This apparent independence from environmental influence is consistent with the findings of Wales et al (2004) who demonstrated that the hand stereotypies of eight girls with RTT were not susceptible to environmental manipulation.…”

“…Oliver et al (1993) found that the function of the self-injury of a child with RTT was to terminate social contact, whereas Iwata et al (1986) concluded that the hand biting of two individuals was independent of environmental circumstances and appeared to be self-stimulatory. Wehmeyer et al (1993); Roane et al (2001) and Wales et al (2004) conducted functional assessments of hand stereotypies. All but one analysis suggested that occurrence was at a high rate and unaffected by environmental conditions.…”

Direct Observation of the Behaviour of Females with Rett Syndrome

The aim was to observe the behaviour of a sample of females with RTT and explore how it was organized in relation to environmental events. Ten participants, all with a less severe form of classic (n = 9) or atypical (n = 1) Rett syndrome (RTT), were filmed at home and at school or day centre. Analysis used real-time data capture software. Observational categories distinguished engagement in social and non-social pursuits, hand stereotypies, self-injury and the receipt of attention from a parent, teacher or carer. Associations between participant behaviour and intake variables and receipt of attention were explored. Concurrent and lagged conditional probabilities between behavioural categories and receipt of attention were calculated. Receipt of adult attention was high. Engagement in activity using the hands was associated with a less severe condition and greater developmental age. Engagement in activity, whether using the hands or not, and social engagement were positively associated with receipt of support. The extent of hand stereotypies varied greatly across participants but was independent of environmental events. Six participants self-injured. There was some evidence that self-injury was related to adult attention. Participants appeared to experience a carer and attention rich environment and their levels of engagement seemed high as a result. As in the more general literature, engagement in activity was related to personal development and to social support. Self-injury contrasted with hand stereotypies in having possible environmental function.

“…However, we contend that repetition is a trivial criterion for classifying behaviors~in the same way as a construct like "sensory dysfunction" is comprehensively uninformative about autistic perceptual and behavioral atypicalities, see Rogers & Ozonoff, 2005!, and that no statement regarding repetitive behaviors as a single entity should be enounced: a putative specificity of repetitive behaviors toward other neurodevelopmental conditions should be investigated separately for each individual behavior e.g., lateral glance!. For example, repetitive hand behaviors appear in both autism and Rett syndrome, but a further examination of hand movement in Rett syndrome has resulted in a finer grained description of this behavior, now included in the phenotype of this conditioñ Wales, Charman, & Mount 2004!. Similarly, the current study provides the preliminary finegrained characterization necessary to study the specificity of atypical visual behaviors to autism compared to other neurodevelopmental disorders.…”

Autistic adults display enhanced and locally oriented low-level perception of static visual information, but diminished perception of some types of movement. The identification of potential precursors, such as atypical perceptual processing, among very young children would be an initial step toward understanding the development of these phenomena. The purpose of this study was to provide an initial measure and interpretation of atypical visual exploratory behaviors toward inanimate objects (AVEBIOs) among young children with autism. A coding system for AVEBIOs was constructed from a corpus of 40 semistandardized assessments of autistic children. The most frequent atypical visual behavior among 15 children aged 33-73 months was lateral glance that was mostly oriented toward moving stimuli and was detected reliably by the experimenters (intraclass correlation > .90). This behavior was more common among autistic than typically developing children of similar verbal mental age and chronological age. As lateral vision is associated with the filtering of high spatial frequency (detail perception) information and the facilitation of high temporal frequencies (movement perception), its high prevalence among very young autistic children may reflect early attempts to regulate and/or optimize both excessive amounts of local information and diminished perception of movement. These findings are initial evidence for the need to consider the neural bases and development of atypical behaviors and their implications for intervention strategies.

“…With respect to the assessment of RS cognitive functions, a focus on two main areas can be identified in the literature: eye gaze communication (Woodyatt and Ozanne, 1992, 1997; von Tetzchner et al, 1996; von Tetzchner, 1997; Umansky and Watson, 1998; Sandberg et al, 2000; Umansky et al, 2001) and communication by means of a functional analysis of behavior patterns (Roane et al, 2001; Baschina et al, 2002; Cass et al, 2003; Sarimski, 2003; Umansky et al, 2003; Wright et al, 2003; Wales et al, 2004), such as abnormal breathing patterns, hand stereotypies, etc. The overall picture that results is that girls with RS are classified within the third or the fourth stage of sensorimotor intelligence, corresponding, respectively, to a mental age of 4–8 and 8–12 months (Olsson and Rett, 1985, 1990; Olsson, 1987) or exceptionally in the transition to the pre-operatory stage (Lindberg, 1988).…”

The goal of this clinical case study is to investigate the possibility of training communication abilities in people with Rett Syndrome (RS). Usually, girls with RS never exceed the sensorimotor stage of development, but the inter-individual variability typical of RS may lead us to doubt the irrevocability of that developmental limit, especially for those girls who are engaged in cognitive rehabilitation. The case study reported here concerns a 21-year-old girl with RS who was engaged in cognitive rehabilitation training based upon the principles of Feuerstein's modificability and mediated learning theory. The training aimed to teach her basic concepts and enhance reading-writing abilities. Statistical analyses showed that the girl reached adequate reading-writing abilities, proving the validity of the cognitive intervention which allowed her to communicate by composing words with her forefinger on an alphabetic table. Although these results need to be cautiously considered as they derive from a single case study, they have implications for future cognitive rehabilitation for deeply impaired clinical conditions as in the case of RS.

An analogue assessment of repetitive hand behaviours in girls and young women with Rett syndrome

Abstract: Overall, environmental manipulations had relatively limited effects on repetitive hand behaviours. Repetitive hand behaviour in Rett syndrome may be maintained by automatic reinforcement or neurochemical processes and may not be primarily influenced by contingent reinforcement.
