Aging cognition: from neuromodulation to representation
TLDR
A paradigm shift towards cross-level conceptions is needed in order to obtain an integrative understanding of cognitive aging phenomena that cuts across neural, information-processing, and behavioral levels, and empirical data at these different levels are reviewed.
Failure to Detect Mismatches Between Intention and Outcome in a Simple Decision Task
TLDR
This work investigated the relation between intention, choice, and introspection, and found that participants failed to notice conspicuous mismatches between their intended choice and the outcome they were presented with, while nevertheless offering introspectively derived reasons for why they chose the way they did.
Listen to the noise: noise is beneficial for cognitive performance in ADHD.
TLDR
Cognitive performance in noisy environments in relation to a neurocomputational model of attention deficit hyperactivity disorder (ADHD) and dopamine is investigated, indicating that ADHD subjects need more noise than controls for optimal cognitive performance.
Stimulus-dependent dopamine release in attention-deficit/hyperactivity disorder.
Attention-deficit/hyperactivity disorder (ADHD) is related to an attenuated and dysfunctional dopamine system. Normally, a high extracellular dopamine level yields a tonic dopaminergic input that
The effects of background white noise on memory performance in inattentive school children
TLDR
Cognitive performance can be moderated by external background white noise stimulation in a non-clinical group of inattentive participants and this finding needs replicating in a larger sample using more noise levels.
FROM CHANGE BLINDNESS TO CHOICE BLINDNESS
The phenomenon of change blindness has received a great deal of attention during the last decade, but very few experiments have examined the effects of the subjective importance of the visual stimuli
Integrative neurocomputational perspectives on cognitive aging, neuromodulation, and representation
TLDR
Considering within an integrative cross-level neurocomputational framework, aging-related decline in dopaminergic neuromodulation reduces the fidelity of neural information and gives rise to less distinctive neural pattern representations that may underlie various facets of aging cognitive and, possibly also, sensorimotor phenomena.
Magic at the marketplace: Choice blindness for the taste of jam and the smell of tea
TLDR
Secretly switched the contents of the sample containers so that the outcome of the choice became the opposite of what the participants intended, demonstrating considerable levels of choice blindness for the taste and smell of two different consumer goods.
How something can be said about telling more than we can know: On choice blindness and introspection
TLDR
In this article, word-frequency and latent semantic analysis (LSA) are used to investigate a corpus of introspective reports collected within the choice blindness paradigm and contrast the introspective reasons given in non-manipulated vs. manipulated trials, but find very few differences between these two groups of reports.
A numerical comparison of three potential learning and forgetting models
TLDR
This paper investigates and discusses three potential models; namely, the learn–forget curve model (LFCM), the recency model (RC), and the power integration diffusion (PID) with their similarities and differences addressed and shows that for a moderate learning scenario, the three models produced very close predictions to one another.
