The author argues, using research reports and models of the functioning of linguistic and logical knowledge in the human mind described in the literature, that in logopedic practice it is worthwhile to take into account the natural, innate knowledge that makes it possible to understand linguistic rules and build the structure of language. This type of knowledge is referred to as logico-linguistic competence and indicates that its proficiency, which can be used in logopaedic practice, is to infer by analogy the relationships of form and content between words/forms of words. It is a proficiency that develops and shapes itself under the influence of cognitive abilities and linguistic experience. It is certainly an individual feature of each person, although natural logic and lexical-grammatical features determine the areas of basic competence.

Hearing loss, aside from age-related degeneration of the nervous system, is one of the most common causes of difficulties in communication and social functioning among seniors. The aim of the study was to identify factors influencing the functioning of people over sixty years of age with hearing impairment. The analysis was made based on a review of the available literature. These factors were classified according to Uri Bronfenbrenner’s bioecological model of human development. This framework made it possible to illustrate the complex interactions of multi-vector factors that, to varying degrees, influence the lives and social functioning of older people within a broad context encompassing health, family, social, legal, organizational and societal conditions.

The article is an attempt to systematize contemporary scientific knowledge regarding tongue-tie diagnosis problems. The authors made a broad review of the literature, trying to find answers to questions that concern speech therapy practitioners in their everyday work. Case studies and publications with a low level of scientific evidence were excluded from the review. The analysis of the literature showed how many extremely important questions remain unanswered and how little reliable information can be used to follow evidence-based practice.
