The phonological-loop model provides a prominent theoretical description of verbal working memory. According to it, serial recall accuracy should be inversely related to the articulatory duration and phonological similarity of verbal items in memorized sequences. Initial tests of these predictions by A. D. Baddeley and colleagues (e.g., A. D. Baddeley, N.(More)
In signal detection theory (SDT), responses are governed by perceptual noise and a flexible decision criterion. Recent criticisms of SDT (see, e.g., Balakrishnan, 1999) have identified violations of its assumptions, and researchers have suggested that SDT fundamentally misrepresents perceptual and decision processes. We hypothesize that, instead, these(More)
The field of artificial intelligence has long surpassed the notion of verbal intelligence envisioned by Tur-ing (1950). Consequently, the Turing Test is primarily viewed as a philosopher's debate or a publicity stunt, and has little relevance to AI researchers. This paper describes the motivation and design of a set of behavioral tests called the Cognitive(More)
The legibility of the letters in the Latin alphabet has been measured numerous times since the beginning of experimental psychology. To identify the theoretical mechanisms attributed to letter identification, we report a comprehensive review of literature, spanning more than a century. This review revealed that identification accuracy has frequently been(More)
Background: Laboratory and field research in cognitive science often uses computer-based tools to design experiments and collect data. Although researchers are typically happy to exchange the data obtained from such studies, sharing the actual software used to collect the data is more difficult. This partly stems from the widespread use of special-purpose(More)
The Task-Taxon-Task method (Anno et al. DNA-TR-95-115, 1996) is a statistical modeling approach to predict performance decrements on behavioral tasks in response to various stressors. We describe the basics of the T3 method and our approach to adapting it to handle more acute stressors, which can require decomposition into task networks via logical or(More)
The Psychology Experimental Building Language Berg Card Sorting Test is an open-source neurobehavioral test. Participants (N = 207, ages 6 to 74) completed the Berg Card Sorting Test. Performance on the first 64 trials were isolated and compared to that on the full-length (128 trials) test. Strong correlations between the short(More)
The fields of artificial intelligence, machine learning, machine vision, and robotic control have all produced successes that demonstrate superiority of machines over the human for narrow problems, and have even sometimes performed tasks that are impossible for humans. Despite these successes, a true human-level machine intelligence remains a far-off dream.(More)
The brain-derived neurotrophic factor gene (BDNF) is known to play an important role in neuroplasticity and cognitive processes. We explored the association of BDNF Val66Met polymorphism with performance in a visual-motor tracking test. One hundred and sixty-seven young, healthy Colombian adults completed a computerized version of the Pursuit Rotor Task,(More)
