Deafness and hard of hearing (DHH) are manifested by differences in communication and the construction of communication competencies. DHH is considered to be one of the most serious handicaps that can influence an individual’s development, depending on the type and level
[8][9][10][11]. Especially from the educational point of view, this disability can have a major effect on the person concerned, in particular as regards communication and thinking capacities. According to the WHO
[12], it is possible to define three basic areas of impact of DHH: the functional, social and emotional, and economic areas. DHH has a fundamentally negative impact on the development of vocabulary and understanding of verbal terms, especially if they are not wholly concrete, which means the saturation of the concept bank, activation of the tongue, and also its use in communication
[13][14][15]. Marschark et al.
[16] suggest that the academic achievement of DHH students is the result of the complex interplay of many factors. These factors include characteristics of the students (e.g., hearing thresholds, language fluencies, mode of communication, and how their communication functions), characteristics of their family environments (e.g., parents’ level of education, socioeconomic status), and experiences inside and outside school (e.g., school placement, having been retained at a grade level). DHH children who grow up in a language-less environment have fundamental problems in the construction of mathematical ideas and thus success in school mathematics and generally speaking in school success
[17][18].
For the education and training of people with hearing impairments, the basis for process education is the same as for hearing people. In the current approach to the education of children and pupils with hearing impairments, it is the merit of effective communication through sign language that enables creativity to develop
[19][20].
2. General Study Details
The extracted articles were written between 1942 and 2019. The focus of research interest on the creativity of individuals with DHH was perhaps at its peak in the 1970s and 1980s (16 out of 30 studies). Twenty-three studies were conducted in the USA, two in Central Europe (Poland and Slovakia), the remainder in the People’s Republic of China, Nigeria, and India, and two in Indonesia. In 10 cases, the research population consisted of DHH individuals only, in 19 cases the research population was a comparison of DHH respondents with the TH population (see
Table 1 for details), and in one case
[21] the creativity of TH and visually impaired individuals was examined. Overall, the number of respondents ranged from 1 to 777. For three studies, the number of respondents was not given. In 9 cases, the gender of the respondents was not stated, and in the remaining 21 cases, the number of women (girls) and men (boys) was explicitly stated. In all these cases, the authors of the studies tried to maintain a balanced gender ratio of respondents. In three cases, the age of the respondents was not given. In the other studies, the ages of the respondents ranged from four to 88 years; the focus of the research was on the population from school age to adolescence. The hearing loss of the respondents was clearly defined only in some cases; where no specific value loss appeared, a note type was given: profoundly deaf, i.e., they did not benefit from hearing aids.

3. Methodology
3.1. Characteristics of Creativity
The first important item that was analyzed for all the selected articles was the characterization of the concept of creativity. In nine articles
[22][24][28][38][39][40][41][42][44], it is not explicitly stated which theory of creativity the authors are drawing on. Daramola et al.
[23] provide a characterization ability to perceive the world in new ways to find hidden patterns, make connections between seemingly unrelated phenomena, and generate solutions. In other cases, the authors draw on Torrance’s theory of creativity. Torrance
[49] characterizes creativity as a complex of abilities, among which he includes sensitivity to problems—the ability to perceive and search for problems, fluency—the ability to produce a multitude of ideas, flexibility—the ability to have a variety of perspectives, originality—the ability to have a new and different perspective, elaboration—the ability to be careful and sophisticated, and redefinition—the ability to define a problem unusually. Ebrahim
[24] Laughton
[35] and Stanzione et al.
[20] then add to Torrance’s notion of creativity with the definition of thinking of Guilford
[50], who distinguished two types of thinking, namely convergent and divergent. The relationship between fluency and verbal creativity is based on the close connection between intelligence and creativity. Creativity is characterized according to the Cattell–Horn–Carroll concept of intelligence as a significant factor at a similar functional level to the fluency of thought and verbal fluency
[51][52].
Divergent thinking allows for a search for different alternatives in the context of problem-solving, from which the most appropriate one is then selected using convergent thinking. According to Guilford
[50], divergent thinking, which is closely related to creativity, has the following components: fluency or the smooth flow of ideas, flexibility or flexibility of thought, originality, sensitivity to problems, redefinition or the ability to use prior knowledge in a new way, and elaboration, i.e., the creation of functional details in problem-solving.
3.2. Study Design
Depending on the chosen design, the articles can be divided into three basic groups: quantitative, mixed, and Text and Opinion Papers.
Quantitative Design
Most of the articles (19 of 30) describe quantitative research. As can be seen from
Table 2, the quasi-experimental research design was used in 15 articles, case series in three, and before and after studies in one. In the case of quasi-experimental research design, except for two articles
[34][45], DHH and TH subjects were compared. Kaltsounis
[34] looked at the effect of race concerning DHH, and Reber and Sherrill
[45] compared the effect of dance training in two DHH groups.
Table 2. Quantitative research—Study design, statistical methods, Aim and Tools.
In two cases
[42][44] the area of interest for exploring creativity was not explicitly stated, while the remaining 17 were about the potential for using the findings in teaching. Of the 19 articles, 14 dealt directly with the relationship between the creativity of children with DHH and children with TH. Of these 14 studies, 4
[30][36][42][44] related the comparison of creativity to other factors such as intelligence, motor skills, or social relationships in the classroom. The remaining five cases involved different characteristics of creativity in individuals with DHH. The authors of two articles
[35][45] considered the possibilities for the development of creativity in DHH individuals, and in three cases
[27][29][34] creativity in DHH individuals was examined as a separate phenomenon with a focus on intelligence or language ability. The Torrance Tests of Creative Thinking were used to determine levels of creativity in 11 cases, supplemented in one case
[43] by the Barron–Welsh Art Scale and in another
[45] by the Dance/Movement Skills Assessment. In the remaining cases, there were different tests of creativity chosen by the researchers concerning the issue at hand (see
Table 2 for details), and in one of these cases
[23] the researchers developed their own instrument. Dramola et al.
[23] reported that the instrument they created was validated by experts in the Unit of Educational Research, Measurement, and Evaluation, Department of Social Sciences Education, Faculty of Education, Loyola University, and the reliability of the instrument would be determined using a split-half method (Cronbach’s α = 0.76).
Mixed Design
A mixed design was used in three articles. In all three cases, it was a comparison of creativity in DHH and TH children. In two cases
[39][40], categories through which the specifics of creativity in DHH individuals were described were developed sequentially. In one case
[46], levels of originality, fluency, flexibility, and elaboration were described for individuals with DHH. Qualitative analyses were supplemented in all cases by descriptive analysis. The relationship between creativity in children with DHH and children with TH was then compared using correlations (see
Table 3).
Table 3. Mixed Research—Design, Methods, Aim, and Tools.
In all three cases, the research results were directed toward the school environment. In two of the cases
[39][40], the effect of language and cognitive level on creativity was investigated in comparison to TH peers. Silver
[46] examined the relationship between cognitive functions and creativity, again in comparison with TH peers. Silver
[46] used the Torrance Tests of Creative Thinking. Marschark and West
[39] and Marschark et al.
[40] chose their instruments: the respondents were asked to tell two stories each time. In both studies, one story was the same and the other was different. The common story is that once while walking through the mountains, they came upon a hidden door and a staircase leading deep into the earth. Below, they found a large cave and a previously unknown civilization. Different stories: They awoke one day to discover that animals and people had exchanged roles. They were asked to tell about seeing someone climbing a ladder and entering the window of a neighbor’s house (see
Table 3).
Text and Opinion Studies
A total of eight articles that could not be classified in the previous categories because of missing or insufficient methodology were included in this group. In addition to being articles that met the inclusion criteria, these are articles that provide substantial information on the issue at hand.
Three studies
[22][24][41] were concerned with describing different activities that can lead to the development of creativity in individuals with DHH. These include various activities in mathematics, drama, or art. In all these cases, the authors of the articles point out that the influence of specific activities can lead to the development of creativity. One article
[31] briefly describes various teaching methods for DHH individuals and compares them in terms of their impact on creativity. Another study
[21] is a brief report comparing the creativity of individuals with DHH and those with visual impairments. Hicks
[28] compares creativity in DHH and TH individuals. However, he adds that regarding sample size, the results of the study cannot be generalized. The last two articles are different. Marschark and Clark
[37] produced a literature review whose purpose was to review and weigh the available evidence concerning the non-linguistic and linguistic creative abilities of DHH children. Marschark et al.
[38] presented information on a newly developed instrument for examining creativity in individuals with DHH. At the same time, they stress the need to approach individuals with DHH individually and to create a research environment for them that does not discriminate against them.
