Anxiety and encoding strategy

Anxiety fosters relational encoding

This paper presents an experimental study of the influence of state-anxiety on relational encoding. It demonstrates that induced state anxiety enhances encoding of relations. Participants in the anxiety group were faster and more accurate in recognizing identical relations in two successive stimuli than the participants in the non-anxiety group.

Structure and strategy in encoding simplified graphs.

Tversky and Schiano (1989) found a systematic bias toward the 45 degrees line in memory for the slopes of identical lines when embedded in graphs, but not in maps, suggesting the use of a cognitive reference frame specifically for encoding meaningful graphs. The present experiments explore this issue further using the linear configurations alone as stimuli. Experiments 1 and 2 demonstrate that ...

A Provincial Anxiety Disorders Strategy

Foreword Historically the disability and costs associated with mental health problems have been underestimated. This is particularly the case with anxiety disorders, the associated burden of disease now understood to be comparable to other major mental health conditions. Anxiety disorders impose a substantial cost on society and markedly compromise the quality of life for those affected. The Pr...

Multidimensional Encoding Strategy of Spiking Neurons

Neural responses in sensory systems are typically triggered by a multitude of stimulus features. Using information theory, we study the encoding accuracy of a population of stochastically spiking neurons characterized by different tuning widths for the different features. The optimal encoding strategy for representing one feature most accurately consists of narrow tuning in the dimension to be ...
