Synthetic aperture radar (SAR) target discrimination is an important stage that distinguishes targets from clutters in the automatic recognition field. However, complex SAR scenes, performance of some traditional discriminators will degrade. As effective tool for one-class classification (OCC), max-margin classifier has attracted much attention discrimination, as it can effectively reduce impac...

When choosing what cases to investigate, do the police discriminate on basis of caste and class? We employ a conjoint design evaluate biases in officers’ preferences for investigation based perpetrator attributes. Conducting survey law enforcement officers Nepal, we find evidence discriminatory practices. Absent constraining protocols that reduce officer discretion, are more likely target offen...

Do the same mechanisms underlie processing of music and language? Recent investigations of this question have yielded inconsistent results. Likely factors contributing to discrepant findings are use of small samples and failure to control for individual differences in cognitive ability. We investigated the relationship between music and speech prosody processing, while controlling for cognitive...

In the present report, rats' performance was assessed in five tasks designed to measure behavioral response to different novel stimuli under different experimental situations. Daily nicotine treatment (0, 0.3 or 1.0 mg / kg) began after the conclusion of the behavioral tasks and continued throughout the experiment. Training of a T-maze visual discrimination task commenced after 11 days of nicot...

Pitch changes that occur in speech and melodies can be described in terms of contour patterns of rises and falls in pitch and the actual pitches at each point in time. This study investigates whether training can improve the perception of these different features. One group of ten adults trained on a pitch-contour discrimination task, a second group trained on an actual-pitch discrimination tas...

Can subjective belief about one's own perceptual competence change one's perception? To address this question, we investigated the influence of self-efficacy on sensory discrimination in two low-level visual tasks: contrast and orientation discrimination. We utilised a pre-post manipulation approach whereby two experimental groups (high and low self-efficacy) and a control group made objective ...
