The development of attention to simple and complex visual stimuli in infants: Behavioral and psychophysiological measures

John E. Richards
2010 Developmental Review  
A continuity is a pattern of looking that is found in the early part of infancy that remains throughout adulthood.  ...  A discontinuity is an emerging sensitivity to the content of the information in the stimulus presentations and alterations in patterns of attention based upon stimulus comprehensibility.  ...  Fig. 1 shows the heart rate change from young infants when viewing simple geometric visual patterns (Richards & Casey, 1991) .  ...

A single-trace dual-process model of episodic memory: A novel computational account of familiarity and recollection

Andrea Greve, David I. Donaldson, Mark C.W. van Rossum
2009 Hippocampus  
Importantly, our putative familiarity and recollection processes exhibit distinct characteristics analogous to those found in empirical data; they diverge in capacity and sensitivity to sparse and correlated  ...  patterns, exhibit distinct ROC curves, and account for performance on both item and associative recognition tests.  ...  In contrast to familiarity, the recollection process does engage the dynamical evolution of the network once a test pattern is presented.  ...

Beyond Views: Measuring and Predicting Engagement in Online Videos [article]

Siqi Wu, Marian-Andrei Rizoiu, Lexing Xie
2018 arXiv   pre-print
Most current research focus on modeling the number of views, but we argue that video engagement, or time spent watching is a more appropriate measure for resource allocation problems in attention, networking  ...  Our observations imply several prospective uses of engagement metrics -- choosing engaging topics for video production, or promoting engaging videos in recommender systems.  ...  (c) Temporal view series (blue) and smoothed daily relative engagement (black dashed) fitted by generalized power-law model at b + c (red).dow, i.e., changing the summations in Eq. 1 to between t-6 and  ...

A commentary on: "Cortical and thalamic excitation mediate the multiphasic responses of striatal cholinergic interneurons to motivationally salient stimuli"

Assunta Pelosi, Domenico Guarino
2015 Frontiers in Neural Circuits  
Although in these experiments the authors could not determine the (cortical or thalamic) origin of inputs, using their PSTH characterization, they found in monkeys a correlation similar to that seen in  ...  pause, and a higher rebound when excited by cortex (dashed line).  ...
