Introduction: Research has indicated that need-supportive learning environments positively influence students' motivation. According to self-determination theory, a need-supportive learning environment is one in which teachers provide structure, autonomy support, and involvement, and thereby support their students' psychological needs for competence, autonomy, and relatedness. In this study, we aimed to explore whether teachers of students with congenital deafblindness provide such an environment and how they adjust their need-supportive teaching to these students. Methods: We conducted an in-depth analysis of teacher-student interactions using a multiple-case-study design. We analyzed videos of teacher-student interactions from the perspective of self-determination theory. Results: We found that successful need support for this group requires careful adjustments for each individual student. Only if the provision of structure, autonomy support, and involvement is tailored to the student can a positive influence on motivation be noticed. Another important finding is that teachers provide more structure and involvement than autonomy support. Discussion: This study showed that need-supportive teaching is important in the education of students with congenital deafblindness. By using video analysis, we were able to point out teaching strategies that led to greater motivation for these students. Implications for practitioners: Motivation is a prerequisite for learning, and teachers' behavior might add to that motivation. This study showed that need support leads to enhanced motivation in students with congenital deafblindness. We provided practical insights that teachers can use to create need-supportive learning environments for these students.

Introduction: In this study, we applied the Intervention Model for Affective Involvement (IMAI) to four participants who are congenitally deafblind and their 16 communication partners in 3 different settings (school, a daytime activities center, and a group home). We examined whether the intervention increased affective involvement between the participants and their communication partners and whether it increased positive emotions and reduced negative emotions in the participants. Methods: We used video observations in a multiple-baseline design across subjects to assess the effects of the 20-week intervention on the communication partners' interactions with the participants. Results: After onset of the intervention, affective involvement increased for three participants, while all four participants showed an increase in positive emotions and a decrease in negative emotions. During follow-up, the positive effect on the participants' behaviors decreased in most cases, but remained visible as compared to the baseline level. Discussion: The findings demonstrate that the IMAI can be successfully applied to persons who are congenitally deafblind. Given the small number of participants, replication of the intervention is recommended. Implications for practitioners: Affective involvement can be increased by training, but it is difficult to maintain this effect over time. Coaching of communication partners on a more permanent basis is recommended to maintain the sharing of emotions between persons who are congenitally deafblind and their communication partners.

The article presents a comprehensive literature review of evidence about the psychological needs of students with hearing and/or visual loss, as well as the effect of their perceptions of need support on their motivation, engagement, and outcomes. The framework applied is based on the Self-Determination Theory of motivation, which addresses the important influence that psychological needs bear on the motivation of students. Seventeen studies were included. Although the results are fragmented in the sense that no study was found to encompass Self-Determination Theory as a whole, researchers were able to assess the psychological needs for competence, autonomy, and relatedness separately. Existing literature reports inconsistent findings concerning the perceived needs of students. A few studies suggest that students feel more competent and related in special classroom settings than they do in mainstream settings. Other studies indicate that the extent to which students feel competent, autonomous, and related is often similar to that of students without sensory loss. Potential implications for educational practice and suggestions for future research are discussed.

This article demonstrates the use of the Diagnostic Intervention Model in everyday practice and the effects of its application in a case study of Kris and his educator using individual coaching. The implications of the case for everyday practice are discussed.

Background: Recent studies have shown that it is possible to foster affective involvement between people with congenital deafblindness and their communication partners. Affective involvement is crucial for well-being, and it is important to know whether it can also be fostered with people who have congenital deafblindness and intellectual disabilities. Methods: This study used a multiple-baseline design to examine whether an intervention based on the Intervention Model for Affective Involvement would (i) increase affective involvement between four participants with congenital deafblindness and intellectual disabilities and their 13 communication partners and (ii) increase the participants' positive emotions and decrease their negative emotions. Results: In all cases, dyadic affective involvement increased, the participants' very positive emotions also increased and the participants' negative emotions decreased. Conclusion: The results indicate that communication partners of persons with congenital deafblindness and intellectual disabilities can be successfully trained to foster affective involvement.

The High Quality Communication intervention aims to stimulate interpersonal communication between individuals with congenital deaf-blindness (CDB) and their social partners. Found effective in multiple-case experiments, the intervention is based on Trevarthen's theory of intersubjective development (Bråten & Trevarthen, 2007), which describes children's innate and developing ability to share subjective states in interpersonal communication and social partners' mediating role in this development. One implication of this theory is that social partners can support the emergence of higher-complexity communication behaviors in individuals who are still developing these behaviors. To test this proposition, communication patterns between individuals with CDB and their parents, teachers, and professional caregivers were analyzed. Analysis of two-event sequences of communicative behaviors showed a highly significant correspondence between the behavior of the social partner and the subsequent behavior of the individual with CDB, confirming that social partners can scaffold higher-complexity communication within interpersonal communication.

Research on Self-Determination Theory has shown that teachers' need-supportive behaviour is associated with student motivation and engagement. The purpose of this study is to examine the effectiveness of an intervention aimed at increasing the motivation of students with congenital and acquired deafblindness by enhancing teachers' need-supportive behaviour. To assess the intervention effect, this study follows a multiple case-study design. Teacher questionnaires were administered and video observations of teacher--student interactions were made during pre-test, post-test and follow-up phases. The results showed that teachers provided involvement most, followed by structure and autonomy support. Teachers' provision of structure and autonomy seems to improve most after the intervention. In general, teachers of students with congenital deafblindness showed larger intervention effects than teachers of students with acquired deafblindness. The results also provide indications that students' levels of engagement improved after the intervention.

Because little is known about teacher-student relationships that involve students with acquired deafblindness, the authors performed a multiple case study with a multiple-method design to investigate the relationship between need-supportive teaching behaviors and student engagement. Using self-determination theory (Deci & Ryan, 2000), they analyzed video observations of interactions. It was found that teachers' provision of structure, autonomy support, and involvement often cooccurs with higher levels of student engagement. Moreover, varying degrees of need support over time seem to result in varying levels of student engagement. Examples are provided of need-supportive teaching behaviors that can be used to foster the motivation of students with acquired deafblindness.

Trevarthen's theory of innate intersubjectivity is relevant to understanding communication problems in children with sensory disabilities. Trevarthen and Aitken used the term "intersubjectivity" to describe "the ability of humans to detect and change each other's minds and behavior". When children lack auditory and/or visual means of interaction, they may not be able to fully develop intersubjectivity, which impedes the development of more complex interpersonal communication. This article presents a review of 31 studies about intersubjectivity in children with sensory disabilities. The results indicate that the intersubjective development of children with sensory disabilities is often delayed. The studies also describe similar strategies for mediating intersubjectivity in children with sensory disabilities and in typical children, but say that specific adaptations may be needed. From an intersubjectivity perspective, symbolic communication delays in children with sensory disabilities may be improved through specific, purposeful forms of social interaction.

This study examined the effects of a 20-week intervention to foster affective involvement during interaction and communication between an adult with congenital deafblindness (CDB) and his caregivers in a group home and a daytime activities center. Using a single-subject design, we examined whether the intervention increased affective involvement between the participant and his caregivers, and whether the participant's positive emotions increased and his negative emotions decreased. In both settings, an increase in affective involvement and very positive emotions coincided with the onset of the intervention, with the clearest effects in the daytime activities center. Negative emotions decreased in the daytime activities center. During follow-up, affective involvement decreased in both settings but remained above baseline. The caregivers indicated that it was easier to share positive emotions than negative emotions. This study demonstrates that it is possible to foster affective involvement with an adult with CDB, both during interaction and communication.

Sensory disabilities may limit a person's development of intersubjectivity, that is, the awareness of self and other, which develops in conjunction with interpersonal communication. This study used intersubjectivity theory to test a new intervention called the High-Quality Communication (HQC) intervention for its effects on a young adult with congenital deafblindness and a developmental age between 1.5 and 4 years. Three of his social partners were trained to support attunement and meaning making with him through education and video feedback. This study measured seven observation categories at three layers of intersubjective development during a baseline and two intervention phases: dyadic interaction, shared emotion, referential communication, meaning negotiation, shared meaning, declarative communication, and shared past experience. The participant's use of conventional communication was included as an additional category. Effects were observed in all observation categories from the baseline through to the intervention phases. Further study of the effectiveness of the HQC intervention is recommended to test whether effects generalize across people and settings.

The article presented here introduces the Intervention Model for Affective Involvement (IMAI), which was designed to train staff members (for example, teachers, caregivers, support workers) to foster affective involvement during interaction and communication with persons who have congenital deaf-blindness. The model is theoretically underpinned, and practical implications and preliminary implementation findings are discussed.

Many people with severe disabilities face difficulties communicating with their communication partners and rely primarily on prelinguistic communication. It is accepted that dynamic assessment can play an important role in improving communication and in measuring a person's ability to learn new communicative skills. Less is known, however, about the application of dynamic assessment in the case of those who communicate at a prelinguistic level. The present article reviewed dynamic assessment procedures that addressed communication abilities in people communicating at a prelinguistic level and young children who communicate using speech, with the aim of identifying key elements of dynamic assessment for persons communicating at a prelinguistic level. The results indicated the need for the identification of contextual variables that support communicative competence, teaching communication partners new skills, and a procedure that is highly individualised. Further research on the validity and reliability of these dynamic assessments is strongly recommended. (Contains 2 tables.)

Little is known about how persons with congenital deaf-blindness use hand movements efficiently for exploring different objects with different textures in different tasks. More knowledge in this area would contribute to the adaptations of educational strategies for encouraging touch and tactile exploration. The study presented in this article investigates the different tactile exploratory procedures used by a woman with congenital deaf-blindness when touching objects with microtextures in three tasks with three types of objects. (Contains 1 table and 2 figures.)

Educators and children with congenital deaf-blindness experience major challenges in building interactions that are reciprocated and sustained. Studies have shown that affect attunement and sensitive responsiveness are crucial for a child to feel recognized and for synchronizing early conversations. The authors previously presented the Diagnostic Intervention Model (DIM) as a guide for designing and implementing interventions to foster harmonious interactions and examined the efficacy of the DIM in the Contact effect study. Considerable effects were found on core interaction categories for both the educators and the children. However, the dyadic category of sustained interaction was not evaluated. In this study, the authors demonstrated the effects of the DIM on sustained interaction within a reciprocal three-turn structure (such as the educator-child-educator or the child-educator-child). They reanalyzed observational data from the Contact effect study and looked at the duration of sustained interaction, the duration of the longest interaction sequence, and the mean number of turns in a sequence. The results are evaluated and discussed. (Contains 4 figures and 1 table.)

This article demonstrates the effectiveness of applying the Diagnostic Intervention Model for fostering harmonious interactions by describing a single-case study. Changes in the caregiver's turn-giving had substantial effects on the child's turn-taking, regulation of intensity, and approving and disapproving answers. The interaction effects were less clear for the child's initiatives. (Contains 1 table and 3 figures.)

The aim of this study was to assess the effect of adaptations for children with low vision of the Bayley Scales, a standardized developmental instrument widely used to assess development in young children. Low vision adaptations were made to the procedures, item instructions and play material of the Dutch version of the Bayley Scales of Infant Development--Second Edition (BSID-II), and the Original and Low Vision versions were administered to children with visual impairment over an interval of two weeks. Although quantitative analysis revealed no significant differences between the Original and Low Vision versions of the test in children's scores, feedback from test administrators indicates that the Low Vision materials make the test easier to administer and more engaging for children. (Contains 1 note, 3 tables, and 2 figures.)

This article describes the application of the Diagnostic Intervention Model and its effects in two case studies of 3-year-old boys, Rolf and Ruud, using individual interaction coaching with their mothers. Positive effects were found for all the target categories in both cases, although an interaction that used materials appeared to be more complex. (Contains 1 table, 1 box, and 3 figures.)

In an earlier publication, we presented the Diagnostic Intervention Model, which can be used as a guide in the design and conduct of interventions to foster harmonious interactions between children who are deaf-blind and their educators. This article demonstrates the use of the model in everyday practice and the effects of its application in two case studies, using team interaction coaching. Implications for everyday practice are discussed. (Contains 2 figures.) [Research for this article was supported by the Stichting Fonds voor Doven and the Stichting Kinderpostzegels Nederland.]

This study examined the effects of an intervention program to improve the quality of daily interaction between six congenitally deaf-blind children and their 14 educators (teachers, caregivers, and mothers). With video analysis as the most important tool, the interaction coaches trained the educators to recognize the children's signals and attune their behaviors to the children's. (Contains references.)
