Stimulus-Stimulus-Pairing to Reduce Stereotypes in Three Children with Autism during Movie Watching

Autism spectrum disorders represent a challenge for professionals, who must include in their individualized educational interventions goals for core symptoms (social–communication and stereotypies/restricted interests) and comorbidities. The narrowness of interests and the high frequency of repetitive behaviors in children with autism often constitute an obstacle for learning and the quality of life, and for their caregivers as well. In the scientific literature, behavioral interventions based on both aversive and, less commonly, positive procedures have been implemented to reduce the frequency of stereotypies. The following study was carried out with the intention of replicating a Stimulus-Stimulus Pairing procedure applied by Nuzzolo-Gomez, Leonard, Ortiz, Rivera and Greer (2002) in order to reduce stereotypies in children. This procedure was applied to three children diagnosed with autism aged five, almost six and seven years, in order to reduce stereotypies when children watched movies. An A-B-A experimental design with three subjects was used for this research. The results showed a decrease in stereotypies in favor of appropriate behaviors.

No Evidence of Robust Noun-Referent Associations in German-Learning 6- to 14-Month-Olds

Work with the looking-while-listening (LWL-) paradigm suggested that 6-month-old English-learning infants associated several labels for common nouns with pictures of their referents: While one distractor picture was present, infants systematically fixated the named target picture. However, recent work revealed constraints of infants' noun comprehension. The age at which these abilities can be obtained appears to relate to the infants' familiarity with the talker, the target language, and word frequency differences in target-distractor pairs. Here, we present further data to this newly established field of research. We tested 42 monolingual German-learning infants aged 6–14 months by means of the LWL-paradigm. Infants saw two pictures side-by-side on a screen, whilst an unfamiliar male talker named one of both. Overall, infants did not fixate the target picture more than the distractor picture. In line with previous results, infants' performance on the task was higher when target and distractor differed within their word frequency—as operationalized by the parental rating of word exposure. Together, our results add further evidence for constraints on early word learning. They point to cross-linguistic differences in early word learning and strengthen the view that infants might use extra-linguistic cues within the stimulus pairing, such as frequency imbalance, to disambiguate between two potential referents.

Failure to show robust noun-referent associations in German-learning infants

Work with the looking-while-listening paradigm suggested that six-month-old English-learning infants associated several common nouns with pictures of their referents. This was evidenced by systematic fixations towards the named target picture (while one distractor picture was present). However, Norwegian-learning infants did not systematically fixate the target pictures until they were 8- to 9-months old, suggesting a cross-linguistic difference in the onset of noun comprehension. Moreover, their success in this task appeared to be modulated by aspects of stimulus pairing, specifically frequency differences between target and distractor: High (resp. low) frequent targets attracted more fixations if they were paired with low (resp. high) frequent distractors. In the present eye-tracking study, we tested 42 monolingual German-learning infants aged six to 14 months by means of a looking-while-listening paradigm. Infants saw two pictures side-by-side on a screen, whilst an unfamiliar male talker named one of both. Overall, infants did not fixate the target picture more than the distractor picture. In line with previous results, infants’ performance on the task was higher when the target and distractor word differed within their word frequency operationalized by the parental rating of word exposure. Therefore, our results further emphasize cross-linguistic differences in early word learning and strengthen the view that infants might use extra-linguistic cues within the stimulus pairing, such as frequency imbalance, to disambiguate between two potential referents.
