We assessed the role of the DRD2 dopaminergic striatal gene polymorphism on performance in unidimensional and conjunctive rule-based category learning tasks. The unidimensional task requires a rule along a single stimulus dimension, while the conjunctive rule task utilizes a combination of two dimensions to distinguish members of each category. The results show that DRD2 C957T T allele carriers...
The role of perceptual load in selective attention to multidimensional objects was investigated by independently manipulating the load along the task-relevant and the task-irrelevant dimensions in the central search array, which was flanked by congruent, incongruent, or neutral peripheral distractors. The relative bottom-up perceptual saliency of these dimensions in capturing attention was mani...
background: workstation design has shift from using single monitor screen to dual monitor screens, which may impose some impacts towards the muscles activity. this study aimed to determine the effect of using dual monitor screen computer to the neck-shoulder muscle activity among computer user. method: this experimental study was conducted in 2015 among 28 healthy students in university malaysi...
Studies of the attentional blink (AB) indicate that similarity modulates the magnitude of the impairment in reporting the second of two masked targets. The present experiments tested whether similarity-based modulations of the AB are determined by all object dimensions or by task-relevant dimensions only. Similarity between target faces was manipulated on two dimensions, only one of which was t...
Objective: People with Anterior Cruciate Ligament (ACL) reconstruction need to have almost automatic postural control to focus on their athletic skills. Continuous cognitive task is a method for removing attention from postural control. The effects of continuous cognitive task on postural control of people with ACL reconstruction has been assessed by laboratory tools; however, its effect using ...
The categorization performance of monkeys on a unidimensional perceptual categorization task was examined with reference to decision bound and exemplar theories of categorization. Three rhesus monkeys were presented with stimuli varying along a single dimension, the displacement of a target light from a fixation point. Left or right saccade responses were probabilistically reinforced according ...
Models and theories of category learning may exaggerate the extent to which people adopt discriminative strategies because of a reliance on the traditional supervised classification task. In the present experiment, this task is contrasted with supervised observational learning as a way of exploring differences between discriminative and generative learning. Categories were defined by a simple u...
In this paper we present our experiments on the RepLab 2014 Reputation Dimension task. RepLab is a competitive challenge for Reputation Management Systems. RepLab 2014’s reputation dimensions task focuses on categorization of Twitter messages with regard to standard reputation dimensions (such as performance, leadership, or innovation). Our approach only relies on the textual content of tweets ...
