Combination and Differentiation Theories of Categorization: A Comparison Using Participants’ Categorization Descriptions

S. Thomas, Aditya Kapoor, Narayanan Srinivasan

Differentiation and Combination theories make different predictions about the order in which information is processed during categorization. Differentiation theory posits that holistic processing of a stimulus occurs before individual features are processed. According to Differentiation theory, overall similarity-based categorization is faster and …

Influence of Personality Traits on Plagiarism Through Collusion in Programming Assignments

P D Parthasarathy, Ishaan Kapoor, Swaroop Joshi, S. Thomas

Educating students about academic integrity expectations has been suggested as one of the ways to reduce malpractice in take-home programming assignments. We test this hypothesis using data collected from an artificial intelligence course with 105 participants (N=105) at a university in India. …

Accurate knowledge about feature diagnosticities leads to less preference for unidimensional strategy.

S. Thomas, Narayanan Srinivasan

In classification learning of artificial stimuli, participants learn the perfectly diagnostic dimension better than the partially diagnostic dimensions. Also, there is a strong preference for a unidimensional categorization based on the perfectly diagnostic dimension. In a different experimental procedure, called array-based classification …

Supervised category learning: When do participants use a partially diagnostic feature?

S. Thomas, Aditya Kapoor, Narayanan Srinivasan

We report a supervised category learning experiment in which the training phase contains both classification and observation learning blocks. To explain the use of different categorization strategies, we propose an account in which use of a stimuli dimension depends on how well …

Effect of a colour-based descriptor and stimuli presentation mode in unsupervised categorization.

S. Thomas, Aditya Kapoor, Narayanan Srinivasan

In unsupervised categorization, studies have shown that fewer stimuli dimensions are used for categorization with serialpresentation compared to concurrent presentation of stimuli. In this study, we investigate how a colour-based multidimen-sional descriptor might affect the number of dimensions used in categorization. Our …

Better learning of partially diagnostic features leads to less unidimensional categorization in supervised category learning.

S. Thomas, Narayanan Srinivasan

Previous studies of supervised category learning show that par-ticipants often prefer a unidimensional categorization strat-egy. Studies also report that the perfectly diagnostic featureis learned better compared to the partially diagnostic features.We replicate these results, and we show that better learning ofpartially diagnostic …

Factors Influencing Categorization Strategy in Visual Category Learning.

S. Thomas, Harish Karnick

Studies in visual category learning show that participants usedifferent category generalization strategies. Some studies re-port a preference for a rule-based strategy, while others reporta preference for a similarity-based strategy. We conducted cat-egory learning experiments in which we varied three variables— family resemblance …

Variable-Gravity Effects on A Single-Phase Partially-Confined Spray Cooling System (Postprint)

Kirk L. Yerkes, Travis Michalak, Kerri Baysinger, Rebekah Puterbaugh et autres

This paper discusses the testing of a single-phase spray cooling system that was flown on the NASA KC-135 Reduced-Gravity Research Aircraft. An experimental package, consisting of a spray chamber coupled to a fluid delivery loop system, was fabricated for variable gravity flight …
