RESUMEN
A growing literature has sought to include mental imagery in fear conditioning studies. Imaginal extinction and imagery rescripting are mental imagery-based interventions that reduce conditioned fear. In the current study, we reviewed the recent findings on the efficacy of imaginal extinction and imagery rescripting as interventions to attenuate conditioned fear responses among healthy individuals. In accordance with the PRISMA guidelines, we conducted a literature search in four databases, PubMed, Scopus, Science Direct, and Web of Science to find published original empirical articles involving imagery-based interventions using a fear conditioning paradigm. The inclusion criteria were (i) use of an imagery-based intervention (either imaginal extinction or imagery rescripting), and (ii) use of a differential fear conditioning paradigm. 13 original articles reporting 15 experimental studies were included in the review. The review revealed that imagery-based interventions are effective in reducing conditioned fear. Although studies have shown that imaginal extinction and standard extinction have comparable effects in fear extinction, many studies have not been conducted to confirm the findings, or explore the underlying mechanisms. We also found the need for a standardized intervention protocol to enhance experimental control in intervention-based fear conditioning studies.

In several research studies, the reactivation extinction paradigm did not effectively prevent the return of fear if administered without any intervention technique. Therefore, in this study, the authors hypothesized that playing music (high valence, low arousal) during the reconsolidation window may be a viable intervention technique for eliminating fear-related responses. A three-day auditory differential fear conditioning paradigm was used to establish fear conditioning. Participants were randomly assigned into three groups, i.e., one control group, standard extinction (SE), and two experimental groups, reactivation extinction Group (RE) and music reactivation extinction (MRE), of twenty participants in each group. Day 1 included the habituation and fear acquisition phases; on Day 2 (after 24 hours), the intervention was conducted, and re-extinction took place on Day 3. Skin conductance responses were used as the primary outcome measure. Results indicated that the MRE group was more effective in reducing fear response than the RE and SE groups in the re-extinction phase. Furthermore, there was no significant difference observed between SE and RE groups. This is the first study known to demonstrate the effectiveness of music intervention in preventing the return of fear in a healthy individual. Therefore, it might also be employed as an intervention strategy (non-pharmacological approach) for military veterans, in emotion regulation, those diagnosed with post-traumatic stress disorder, and those suffering from specific phobias.

Information and communication technology (ICT) can empower the older people and improve their quality of life by sustaining functional independence and effective communication. Nonetheless, in developing countries like India, technology acceptance and use among the older people is limited. Therefore, there is a need to systematically understand the plausible difficulties limiting technology use and the expectations of the older people regarding ICT use. Hence, the present study is a qualitative inquiry to explore the needs, attitudes and perceived limitations of the ICT platforms among the older people. Twenty healthy volunteers across various states of India, between 60 and 75 years were recruited online via purposive sampling. A brief demographic survey was administered online using Google Forms, followed by telephonic semi-structured interviews. Thematic Analysis using inductive and deductive coding was employed to analyse the interview transcripts. Thematic analysis yielded four overarching themes- (i) Usability of ICT, (ii) Anxiety and privacy concerns, (iii) Self-perception of technology use and (iv) Need for technology literacy. The emerging themes reflected the perceptions of the older people towards ICT and identified several psycho-social factors impacting technology acceptance among the older people. The findings suggest that several psychological factors like anxiety, motivation, interest and self-efficacy play a role in technology acceptance among the older people. Additionally, user-friendly interfaces and training on technology use may enhance technology acceptance among older users.
