Alternate antagonism with paradoxical translation behavior in two bilingual aphasic patients

Two patients presenting a pattern of recovery yet unreported in the literature were observed, one in Paris, the other in Montreal. Both patients alternately suffered severe word-finding difficulties in one language while remaining relatively fluent in the other. They retained good comprehension in both of their languages at all times. They were able to translate correctly and without hesitation from the language they could speak well at the time into the language unavailable for spontaneous use, but were unable to translate from their temporarily poor language (which they understood well) into the language which they could speak quite well at the time.     

Underestimation of prior remembering and susceptibility to false memories: two sides of the same coin?

In two studies, we explored whether susceptibility to false memories and the underestimation of prior memories (i.e., forgot-it-all-along effect) tap overlapping memory phenomena. Study 1 investigated this issue by administering the Deese/Roediger–McDermott task (DRM) and the forgot-it-all-along (FIA) task to an undergraduate sample (N = 110). It was furthermore explored how performances on these tasks correlate with clinically relevant traits such as fantasy proneness, dissociative experiences, and cognitive efficiency. Results show that FIA and DRM performances are relatively independent from each other, suggesting that these measures empirically apparently refer to separate dimensions. However, they do not seem to define different profiles in terms of dissociation, fantasy proneness, and cognitive efficiency. Study 2 replicated the finding of relative independence between false memory propensity (as measured with the DRM task) and the underestimation of prior memories (as measured with an autobiographical memory dating task) in people with a history of childhood sexual abuse (N = 35).     

Cross-cultural examination of the tripartite model in adults

Clark and Watson's (1991) tripartite model is commonly viewed as the preferred model for examining the relationship between anxiety and depression. The tripartite model proposes that the overlap and distinction between anxiety and depression can be best understood along three dimensions: positive affect, negative affect, and physiological hyperarousal. Although the tripartite model has received support in a wide variety of samples, little has been done to examine whether the tripartite model holds cross-culturally. Using a highly diverse sample of undergraduate students (n = 923), this study set out to determine the generalizability of the tripartite model among students who identified themselves as African American/Black (non-Hispanic), Caucasian/White (non-Hispanic), Hispanic/Latino(a), and Asian. The results of the present study suggest that the model fits generally for each group, but the study did not find cross-group equivalence in the relationships between constructs. Possible reasons for the lack of cross-group equivalence, as well as limitations of this study, are also discussed.     

Motivation Among Pre-intermediate Iranian Language Learners: From Explicit Knowledge Toward Implicit Syntactic Development

The variable success in learning a second language (L2) may be best explained by varying degrees of motivation. This study investigated whether individual differences in appraisal dimensions of motivation explained explicit and implicit syntactic knowledge. Participants learned three syntactic structures under implicit and explicit training conditions. They also completed two motivation questionnaires before instruction. Syntactic development was assessed at early and late stages of acquisition. Results indicated superior performance on the tests of explicit knowledge, but a limited effect for the role of motivation in its development. However, with improvement in implicit knowledge at delayed testing, positive relationships emerged with several motivational dimensions. The results support L2 theoretical perspectives that posit different roles for explicit and implicit knowledge at early and late stages of L2 grammar, respectively. The findings also indicate that variation in learners’ patterns of stimulus appraisals may contribute to variable success in the development of implicit knowledge.     

Can physical activity be used as a tool to reduce depression in patients after a cardiac event? What is the evidence? A systematic literature study

A reduction in the incidence of cardiovascular diseases (CVD) has been reported in the Western world, but post‐infarction depression often occurs and is related to poor medical outcomes. The aim of this study was to examine the scientific literature by a systematic review, in order to find evidence for whether physical activity can be a tool to reduce depression in patients who have suffered a cardiac event. Three databases were systematically searched (PubMed, CINAHL, and Cochrane), and the GRADE protocol was used in combination with a revised Amstar‐protocol for the systematic review. Scientific reports fitting the area were scarce. Finally, ten studies were included in this study: one meta‐analysis, five randomized controlled trials, and four clinical trials. The results showed low to moderate evidence for the use of low to moderate levels of exercise as a tool to reduce depression in post‐coronary artery event patients. This study concluded positive effects of physical activity as a tool to reduce depression in post‐coronary artery event patients. Physiotherapists could be further involved in increasing physical activity after cardiac events. More studies are needed in the area.
