For this reason, we also evaluate the average number of categorizations in which users reported additional tags and observe the following facts.
We trained two monkeys on a speed categorization task in which they categorized stimulus speed depending on the position of two different category boundaries.
We used a semantic categorization task in which events were words representing either artifact or natural kinds concepts.
Here we use a go/no-go categorization task in which subjects have to decide whether a previously unseen photograph, flashed on for just 20 ms, contains an animal.
These null findings are contrary to the congruence effects that we have observed in our prior categorization work, in which participants classified women's displayed affect into sexual-interest, rejection, friendliness, or sadness categories (e.g., men showed greater sensitivity to women's sexual interest when the women dressed provocatively rather than conservatively).
To study what aspects of cognitive flexible behavior are monitored in the caudate nucleus we recorded neuronal activity during a categorization task in which decision criteria changed rapidly across trials.
3G-sex is a categorization system in which ~99% of human subjects are identified as either "male" or "female", and identification with either category entails having all the characteristics of that category (i.e., "female" = XX, ovaries, uterus, fallopian tubes, vagina, labia minora and majora, clitoris, and "male" = XY, testes, prostate, seminal vesicles, scrotum, penis).
A two-level object categorization scenario is tested in which pre-categorization is based on coarse scales only and final categorization on coarse plus fine scales.
It also mimics the human mind's categorization of things, in which objects are quickly and accurately (based on learned visual cues) divided into immediate, distant, and various degrees in between.
To account for the fact that child reports on parental education are less reliable, a rather crude categorization is used in which pupils whose parents had attained a tertiary degree are compared with those whose parents had attained a lower educational level.
