Attention and awareness in human learning and decision making
… three experiments utilised a modification of the Serial Reaction Time task in order to measure the interaction of implicit and explicit learning processes. The results did not show evidence for an interaction, but did exhibit an effect of explicit knowledge of the underlying rules of the task. …

Perception, expectation and uncertainty in autism
… in a similar manner. In chapter 6, I present a serial reaction time task which tests whether autistic individuals are able to update predictive information flexibly. The results found that autistic individuals, relative to controls, showed an overall reduction in the extent to which they …

Circadian disruption causes deficits in attention and response inhibition in adult Long-Evans rats
… the regular hours of ‘9 to 5’ (shift work) and untimely exposure to light (light-at-night, LAN). Our study investigated the effects of 2 models of circadian disruption on response inhibition, which has previously been unaddressed, and attention using a 5-choice serial reaction time task (5-CSRTT). …

Role of prefrontal cortex and cholinergic modulation in attentional performance in rats
… touchscreen-based rodent continuous performance task (rCPT), which assesses sustained, focused attention in essentially an identical manner to CPTs commonly used in the clinic. Findings were compared to performance on the well-characterised 5-choice serial reaction time task (5-CSRTT), which …

Speed of task acquisition in sign-tracker and goal-tracker rats using the 5-CSRTT
… une tâche expérimentale attentionnelle (5-choice serial reaction time task, 5-CSRTT) afin d'évaluer, entre autres, la vitesse d'apprentissage, leur capacité attentionnelle et le niveau de motivation. Une différence significative (F (2,46) = 3.44, p=0.04) entre la vitesse d'apprentissage des trois …

Cognitive dysfunction and schizophrenia : Modelling attentional impairment with psychotomimetics. Investigating attentional impairment and structural brain abnormalities following phencyclidine administration: Enhancing translatability between preclinical and clinical tests of attention utilising the modified 5-choice task in rats - the 5-Choice Continuous Performance Test.
… impairment was tested, using the 5-choice serial reaction time task (5-CSRTT). The 5-CSRTT assesses not only visuospatial attention, but also components of impulsivity, compulsivity, speed of processing and motivation. It was determined that an additional task-related intervention that …

Touchscreen Assessment of Motivation and Reinforcement-Related Choice Behaviour in Mice
… and optimisation of a set of touchscreen tasks for the assessment of motivation and reinforcement processes in mice. Changes in motivational state and reinforcement sensitivity are characteristic of depressive symptoms in a number of neuropsychiatric and neurodegenerative conditions. …

Associative Processes in Statistical Learning: Paradoxical Predictions of the Past
… word in the English language is the). The Serial Reaction Time (SRT) task, a model for studying sequential behavior, is used to quantify sensitivity to sequential constraints present in structured environments (Nissen & Bullemer, 1987). The SRT task requires Ss to make a unique response to …

Neural and psychological mediators of trait impulsivity: cortico-striatal circuitry and catecholaminergic neuromodulation
… in experimental rats trained on the 5-choice serial reaction time task (5CSRTT). The psychological processes involved in this behaviour are yet to be fully understood. However, aspects of sustained attention, urgency, motivation, and delay-aversion are all likely to play a role in shaping this …
