RESUMEN
OBJECTIVE: Neurological conditions, such as multiple sclerosis and stroke, may impair memory and language. A technique called retrieval practice (RP) may improve memory and language outcomes in such clinical populations. The RP effect refers to the finding that retrieving information from memory leads to better long-term retention than restudying the same information. Although the benefits of RP have been repeatedly observed in healthy populations, less is known about its potential applications in cognitive rehabilitation in clinical populations. Here we review the RP literature in populations with acquired memory and language impairments. METHOD: Systematic searches for studies published before January 2020 were conducted on Elsevier, PsycARTICLES, PsycINFO, Pubmed, Web of Science, and Wiley Online Library, with the terms "retrieval practice"/"testing effect" and "cognitive rehabilitation". In addition, backward and forward snowballing were used to allow the identification of important publications missed by the initial search. Studies were included if they were peer-reviewed, empirical work in which memory or language outcome measures were compared between an RP condition and a re-exposure-control condition in patients with acquired memory or language impairments. RESULTS: Sixteen articles fulfilled the inclusion criteria. Studies from memory-impaired samples were relatively homogeneous with respect to experimental protocols and materials and favored RP over control conditions. The results were mostly positive despite short retention intervals and predominantly single-session designs. Similarly, studies from language-impaired samples focused on naming impairments in patients with aphasia and also favored RP over name repetition. CONCLUSION: The results indicate that RP is a viable technique for cognitive rehabilitation.
RESUMEN
Peers are the preferred source of help for Brazilian adolescents who experience dating violence. However, they are not always the best informants for effective responses for dealing with situations of violence in romantic relationships among peers. This experimental study aimed to evaluate the short-term efficacy of three aspects of a peer- and bystander approach-based intervention: the intent to offer help, empathy, and bystander attitudes in response to dating violence in a Brazilian sample of adolescents. The study's participants were 33 adolescents randomized in two groups: experimental group (EG, n = 14) and control group (CG, n = 19). The EG underwent three weekly intervention sessions of 90 min each on the healthy versus violent romantic relationships, the quality of friendship in the peer network, and the role of the bystander, while the CG received no intervention. Evaluations were performed 1 week before and two and half months after the intervention. Statistically significant differences between EG and CG at post-test were not found in intention to help, empathy, and bystander attitudes. Future studies should include evaluations of larger samples and mid- and long-term follow-ups to identify patterns of change over the long term as well as examine barriers to utilization of bystander behaviors by adolescents in Brazilian culture.
