Stimulus-Stimulus Pairing of Vocalizations: A Systematic Replication

The current study replicated an enhanced stimulus-stimulus pairing (SSP) procedure used by Esch et al. (Journal of Applied Behavior Analysis 42: 42–225, 2009) for increasing vocalizations in children with autism. The enhanced SSP procedure consisted of pairing target vocalizations with high-preference items, interspersed target and nontarget trials, an observing response, and the presentation of the vocalizations in “motherese” speech. Results showed substantial increases in target vocalizations above baseline levels and above nontarget vocalizations for two of three participants.     

The Effects of a Stimulus-Stimulus Pairing Procedure on the Unprompted Vocalizations of a Young Child Diagnosed with Autism

The current study evaluated the effects of a stimulus-stimulus pairing procedure intended to increase spontaneous vocalizations of a young child diagnosed with autism. A multiple-baseline design across two target phonemes was used to evaluate the effects of the pairing procedure on the frequency of phonemes uttered by the participant. Data were collected during presession, postsession, and follow-up periods across three conditions: Baseline, Control, and Pairing. During the Pairing conditions, a target phoneme was repeatedly vocalized by the experimenter and was systematically paired with preferred stimuli. Results from postsession observations following the pairing condition evidenced no increase in the target sounds. Practical and theoretical implications of the results are discussed.     

Stimulus-Stimulus Pairing and Subsequent Mand Acquisition of Children with Various Levels of Verbal Repertoires

Effects of a stimulus-stimulus pairing procedure on the subsequent acquisition of mand operants were investigated. An attempt was made to shape novel sounds that emerged through the pairing procedure into a mand. Six children, aged two to five years, with moderate to severe language and communication delays, participated. Two conditions were used following the pairing condition: postpairing and direct reinforcement. The emergence of mands was compared across these conditions. An additional analysis was made of the relation between participants'' baseline verbal repertoires and the effects of the pairing and the emergence of mands. Results indicate the possibility of stimulus control from a stimulus-stimulus pairing to mand as shown in two of the participants who had demonstrated high rates of vocal play and low to no verbal repertoire prior to this study. Target vocal sounds during postpairing and direct reinforcement condition remained at zero to low levels for participants with high verbal repertoire and little vocal play, warranting future studies on relations between the pre-existing verbal repertoire and the effectiveness of stimulus-stimulus pairing.     

Using Stimulus-Stimulus Pairing and Direct Reinforcement to Teach Vocal Verbal Behavior to Young Children With Autism

In this study the effect of a stimulus-stimulus pairing procedure was used as part of a clinical investigation to increase vocalizations for two young children diagnosed with autism. This procedure involved pairing a vocal sound with a preferred stimulus (e.g., toy) to condition automatic reinforcement. In addition, this study assessed the effects of a direct reinforcement procedure to bring a vocalization under echoic control following the pairing procedure for 1 of the participants. The results showed the pairing procedure was used successfully to increase a vocalization for one of the participants, and the vocalization was brought under echoic control.     

Evaluating Stimulus-Stimulus Pairing and Direct Reinforcement in the Establishment of an Echoic Repertoire of Children Diagnosed with Autism

Many children with autism do not imitate adult vocalizations, an important skill in learning to talk. Pairing adult vocalizations with preferred stimuli has been shown to increase free-operant vocalizations but effects are temporary; thus, direct reinforcement may be necessary to establish durable vocal behaviors. In Experiment 1, directly reinforced echoic responses did not increase following stimulus-stimulus pairings in three children with autism. Similarly, pairings did not increase free-operant vocalizations in Experiment 2, a replication of Miguel et al. (2002). Experiment 3 demonstrated that shaping increased vowel frequency for one participant. Results suggest that variables are yet to be delineated that influence effectiveness of a stimulus-stimulus pairing procedure on vocalization frequency and acquisition of a verbal operant following such pairings.

Using a Lag Schedule of Reinforcement to Increase Response Variability in Children With Autism Spectrum Disorders

Lag reinforcement schedules have been shown in previous research to be an effective intervention for teaching verbal and nonverbal response variability to individuals with developmental disabilities. In more recent research, variability itself has been considered a reinforceable behavior in its own right (Susa & Schlinger, The Analysis of Verbal Behavior, 18, 125–130, 2012). Lag x schedules of reinforcement can be used to teach variability by using contingencies that require responses to differ from previous responses. The present study extended Susa and Schlinger’s, The Analysis of Verbal Behavior, 18, 125–130, (2012) research by using 3 social questions instead of 1 in a random rotation and included probes to test for generality. A changing-criterion design was used to evaluate the results with one 11-year-old female participant diagnosed with autism. During baseline, the participant provided little variability, with rote responses. During the Lag 1 and Lag 2 phases, appropriate variable verbal responding increased with the use of echoic prompts, visual aids, and an error correction procedure. Further, the results also showed that the participant learned to vary her responses by demonstrating the ability to emit 11 novel prompted responses and 13 spontaneous responses.In addition, the participant was able to retain the skills learned in a maintenance probe conducted 4 weeks postintervention.     

Using a lag schedule to increase variability of verbal responding in an individual with autism

Research has shown that reinforcing novel behaviors can increase the number of different ways that an individual behaves (Goetz & Baer, 1973; Pryor, Haag, & O'Reilly, 1969). However, it was not until more recently that researchers began to consider variability to be a reinforceable operant in and of itself (Neuringer, 2002). More specifically, Neuringer suggested that variability can be taught using a Lag x schedule of reinforcement, in which x refers to the number of previous responses from which the current response must differ in order for reinforcement to occur (Page & Neuringer, 1985). The purpose of the present study was to extend one of the first studies of a Lag x schedule on verbal responses with human subjects (Lee, McComas, & Jawor, 2002), by increasing the lag criteria while attempting to address some of methodological limitations of the study. The participant was a 7-year-old male with autism. A changing criterion design was used and results showed that 3 novel responses were acquired and varied according to the lag schedule of reinforcement.     

Suspended Sorrow: The Crisis in Understanding the Diagnosis for the Mothers of Children with A Disorder of Sex Development

ABSTRACT.Objectives: We conducted a survey to obtain information concerning how mothers of children with DSD represent the diagnosis. Methods: We examined our findings through IPA methodology. Results: We observed a crisis of meaning, based on the inability to classify their child with a milestone of the social experience: the gender category. That risks of slipping into adempitive adherences to medical knowledge or hasty decisions about the health of the child. Conclusions: It's necessary to structure spaces with medical-psychological teams, for allowing these families to manage the condition in relation to the choices, and the daily context, of their children.     

Extending reading research with a focus on cultural understanding and research on intercultural communication: an empirical investigation in Argentina

The work presented here is an empirical study of how advanced learners of English as a foreign language in Argentina access and understand the culture-specific dimensions of literary narrative texts. It has three purposes. First, to extend research into reading in a foreign language to take account of the culture-specific content of texts. Second, to extend the focus of research on intercultural communication to include the analysis of reading processes. Finally, to introduce an approach to the analysis of the cultural dimension of the reading process using a new model of levels of cultural understanding. It is argued that cultural understanding goes beyond the quantification of prior knowledge or background knowledge in the form of idea units as evidence of the comprehension process. In this sense, the proposed model succeeds in portraying a more detailed picture of cultural understanding in this setting.     

Supporting people with intellectual disabilities to take part in focus groups: reflections on a research project

This paper discusses how support offered to people with intellectual disabilities who take part in research might affect the resultant data. People with intellectual disabilities from a long‐stay hospital, a day centre and a self‐advocacy group, all in the UK, participated in focus groups during a research project on nurse advocacy. Their supporters were staff employed by those services who were familiar with and to the group members. The support given to participants reflected the ethos of the services involved, relating either to the medical or the social model of disability. The paper argues that the philosophy of care influencing supporters of research participants with intellectual disabilities may have profound effects on the support provided. It may facilitate or inhibit open exchange of information. It may also aid clarification or cause contamination of the resultant data.
