Age-preserved semantic memory and the CRUNCH effect manifested as differential semantic control networks: An fMRI study.

PLoS One 2021 15;16(6):e0249948. Epub 2021 Jun 15.

Interdisciplinary School of Health Sciences, University of Ottawa, Ottawa, Ontario, Canada.

Semantic memory representations are overall well-maintained in aging whereas semantic control is thought to be more affected. To explain this phenomenon, this study aims to test the predictions of the Compensation Related Utilization of Neural Circuits Hypothesis (CRUNCH) focusing on task demands in aging as a possible framework. The CRUNCH effect would manifest itself in semantic tasks through a compensatory increase in neural activation in semantic control network regions but only up to a certain threshold of task demands.

Older and younger adults' hindsight bias after positive and negative outcomes.

Mem Cognit 2021 Jun 15. Epub 2021 Jun 15.

Heinrich-Heine-Universität Düsseldorf, Institute for Experimental Psychology, 40225, Düsseldorf, Germany.

After learning about facts or outcomes of events, people overestimate in hindsight what they knew in foresight. Prior research has shown that this hindsight bias is more pronounced in older than in younger adults. However, this robust finding is based primarily on a specific paradigm that requires generating and recalling numerical judgments to general knowledge questions that deal with emotionally neutral content.

Why Does Cognitive Training Yield Inconsistent Benefits? A Meta-Analysis of Individual Differences in Baseline Cognitive Abilities and Training Outcomes.

Front Psychol 2021 26;12:662139. Epub 2021 May 26.

Cognition in Context Lab, Department of Psychology and Center for Mind & Brain, University of California, Davis, Davis, CA, United States.

Despite growing interest in improving cognitive abilities across the lifespan through training, the benefits of cognitive training are inconsistent. One powerful contributor may be that individuals arrive at interventions with different baseline levels of the cognitive skill being trained. Some evidence suggests poor performers benefit the most from cognitive training, showing compensation for their weak abilities, while other evidence suggests that high performers benefit most, experiencing a magnification of their abilities.

Glycinergic axonal inhibition subserves acute spatial sensitivity to sudden increases in sound intensity.

Elife 2021 Jun 14;10. Epub 2021 Jun 14.

University of Leuven, Leuven, Belgium.

Locomotion generates adventitious sounds which enable detection and localization of predators and prey. Such sounds contain brisk changes or transients in amplitude. We investigated the hypothesis that ill-understood temporal specializations in binaural circuits subserve lateralization of such sound transients, based on different time of arrival at the ears (interaural time differences, ITDs).

Linking inhibitory control to math achievement via comparison of conflicting decimal numbers.

Cognition 2021 Jun 10;214:104767. Epub 2021 Jun 10.

Department of Psychology, Rutgers University, Newark, USA; Behavioral Neural Sciences Graduate Program, Rutgers University, Newark, USA. Electronic address:

The relationship between executive functions (EF) and academic achievement is well-established, but leveraging this insight to improve educational outcomes remains elusive. Here, we propose a framework for relating the role of specific EF on specific precursor skills that support later academic learning. Starting from the premise that executive functions contribute to general math skills both directly - supporting the execution of problem solving strategies - and indirectly - supporting the acquisition of precursor mathematical content, we hypothesize that the contribution of domain-general EF capacities to precursor skills that support later learning can help explain relations between EF and overall math skills.

Do the young and the old perceive emotional intervals differently when shown on a younger or older face?

Cogn Process 2021 Jun 11. Epub 2021 Jun 11.

Department of General Psychology, University of Padova, Via Venezia, 8, 35131, Padova, Italy.

Many authors have analysed the effects of emotion recognition on time perception, showing that the more arousing the stimuli are the greater is the effect on duration perception. Visual stimuli, in particular faces, are the most recurrent stimuli employed in the literature. However, pictures in which emotional faces of older individuals have rarely been used, and when used, only young participants were tested. Read More

The importance of working memory capacity for improving speech in noise comprehension in children with hearing aid.

Int J Pediatr Otorhinolaryngol 2021 May 24;147:110774. Epub 2021 May 24.

Department of Biostatistics, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran. Electronic address:

Background: One of the most common complaints of hearing aid users is difficulty in receiving speech in noise which is very important for all hearing impaired specially children with limited auditory and language experiences. Since working memory plays a significant role in speech perception, especially in challenging auditory situations such as background noise, it is likely that differences in its performance and capacity may impair the ability to understand speech in noise in hearing aid users. Therefore, we aimed to compare memory capacity between two groups of children using hearing aids in both ears, who differed only in the ability to understand speech in noise. Read More
