The ability to make purchases in community settings is highly advantageous as it allows individuals freedom of choice and the ability to function within their own community. Independence and autonomy is especially important for individuals with intellectual disabilities (ID’s), however prerequisite knowledge of money concepts required for making cash purchases may be too complex for individuals with cognitive challenges. The use of EFTPOS cards to make purchases is a comparatively easy process with limited prerequisite skills required therefore, is an ideal starting point for teaching purchasing skills to individuals with cognitive challenges. Video modelling (VM) and video self-modelling (VSM) procedures have shown to be effective and efficient instructional techniques for teaching various skills to individuals with ID’s however, research on the effectiveness and efficiency of these procedures with individuals with Down syndrome (DS) or with EFTPOS purchases is minimal. This study aimed to examine the effectiveness of VM and VSM interventions in teaching independent EFTPOS purchasing skills to 6 young adults with DS using a non-concurrent within-participant design. The results indicates that both VM and VSM interventions were effective and efficient as all 6 participants exhibited increases in task acquisition with the introduction of the intervention, and 5 of the 6 were able to consistently use their EFTPOS cards to purchase chosen items throughout intervention and follow-up generalisation probes (2 weeks postintervention). Therefore, this study suggests both VM and VSM may be equally effective for teaching young adults with DS EFTPOS purchasing skills in community stores.

Background: Children with Asperger’s Syndrome have deficits in daily social communication and pragmatic skills of varying degrees. A lack of appropriate use of eye contact during communication is a well-described marker of the social-pragmatic deficit that is characteristic of children with Asperger’s Syndrome. This study investigated the effectiveness of a combined therapy approach including social stories, video-modelling and computers to address the impaired eye contact. Method: Five participants, between the ages of 6-12 years, with a diagnosis of Asperger’s Syndrome took part. A multiple single subject ABAB design was applied for the purpose of this study. Results: There was an overall improvement in eye contact across all five participants. Other pragmatic behaviours were also positively affected. Conclusions: A combined type of intervention may be used effectively to improve the non-verbal social skills, specifically eye contact, in children with Asperger’s Syndrome. Clinical and theoretical implications of the findings are discussed.

Video modelling has been shown to be an effective intervention with autistic individuals as it takes into account autistic characteristics of those individuals. Research on video self modelling and video peer modelling with this population has shown both are effective. The purpose of this study was to replicate past findings that video modelling is an effective strategy for autistic individuals, and to compare video self modelling with video peer modelling, to determine which is more effective. The studies here used multiple baselines with alternating treatments designs with 6 participants across two target behaviours; emotional recognition and oral comprehension. The first compared the video modelling methods and found neither method increased the target behaviours to criterion, for 5 out of the 6 participants. For 1 participant the criterion was only reached for the video self modelling condition for the target behaviour 'oral comprehension'. The second study first examined the effectiveness of video self modelling and video peer modelling with supplementary assistance for 4 participants. Second, it examined a new peer video for a 5th participant, and third, it compared the two video modelling methods (with supplementary assistance). Results indicated 1 participant reached the criterion in both video modelling conditions, 1 participant showed improvements and 2 participants never increased responding. This study indicated that clarity of speech produced by the peer participant in the peer video, may have contributed to a participant's level of correct responding. This is because a new peer video used during the second study dramatically increased this participants responding. Intervention fidelity, generalisation and follow-up data were examined. Measures of intervention fidelity indicated procedural reliability. Generalisation was unsuccessful across three measures and follow-up data indicated similar trends to intervention. Only video self modelling effects remained at criterion during follow-up. Results are discussed with reference to limitations, future research and implications for practice.

Research has shown that video modelling can improve social behaviours in children with ASD. In addition, research in behaviour modelling training from the field of organisational psychology has shown that using a mix of positive and negative exemplars can assist in acquisition and generalisation of a skill. The current study compared the use of one negative and one positive exemplar, with the use of two positive exemplars to determine which combination would result in faster acquisition and/or superior generalisation of a skill. No other studies have examined this with children diagnosed with ASD. Seven children, aged between 5 and 15 years, and diagnosed with ASD participated in a multiple baseline design across children; within child across two modelling conditions; and within each modelling condition across two tasks. In one condition, a participant watched a video containing one exemplar of a model (same sex and of similar age but with normal development) perform a task the wrong way, and one exemplar of the same model perform the same task the right way (wrong/right). In another condition, the participant watched a video containing two different exemplars of the model perform a matched task the right way (right/right). During the intervention, 1 participant refused to watch the videos. For 13 of the 16 tasks, where training was completed, participants either reached criterion or made some gains in acquisition of the social skills. However, for seven of the tasks criterion was not reached. Generally, neither modelling condition was superior in acquisition or generalisation of the targeted social skills. Confounds occurring during the course of the study may have contributed to the equivocal results. For some children with ASD, video modelling in combination with the delivery of preferred reinforcers may be required for successful skill acquisition. Further implications, particularly the potential negative effects of vicarious reinforcement when an observer does not gain reinforcement for imitation are discussed, as are recommendations for future research.
