In the 1985 study by Moran and Desimone, which examined the effects of selective attention on the neural activity of the visual cortex in monkeys, what was the key finding about how attention influences neural responses?1 pointA. Attention selectively enhances the neural response to stimuli within the receptive field that are behaviorally relevant, while suppressing responses to irrelevant stimuli.B. Attention has no effect on neural activity in the visual cortex, indicating that visual processing is unaffected by attentional focus.C. Attention uniformly increases neural responses across all stimuli within the receptive field, suggesting a generalized effect of attentional arousal.D. Attention leads to a decrease in neural response to all stimuli within the receptive field, indicating a global suppressive effect on neural activity.

Which of the following is an advantage of selective attention?Group of answer choicesA. Selective attention allows us not to be overwhelmed by the millions of sensory messages that are being processed by our nervous system.B. Selective attention determines the sensitivity of various sensory receptor neurons.C. Selective attention allows us to completely attend to multiple stimuli simultaneously.D. Selective attention prevents us from attending to potentially important stimuli once we have filtered them out of attention.

Attention is best characterised as a(n):Question 24Answera.specific brain process, dependent on the parietal lobe.b.single mechanism that functions differently in different circumstances.c.capacity that only comes into being through practice.d.achievement that depends on many different processes.

Which of the following observations is consistent with the idea that learned changes in attention may sometimes serve an explorative function, rather than exploitative function?Group of answer choicesLearning of a CS-US relationship proceeds slower if the CS and US have previously been presented in an explicitly uncorrelated fashion.Under some circumstances, attention in humans appears to show conditioning-like properties, producing automatic changes in how we process complex visual stimuli.People tend to learn faster about predictive cues that have been predictive in other similar learning contexts.Learning an easy version of a discrimination can substantially improve subsequent discrimination on a harder version of the discrimination.Rats continue to orient towards a partially reinforced CS for longer than they do to either a continuously reinforced CS or a non-reinforced CS.

Which of the following statements best describes the function of attention mechanisms in neural networks?Question 30Answera.They ignore certain input features entirelyb.They allocate computational resources evenly across all input features.c. They prioritize features randomly.d. They selectively weigh input features based on their relevance to the task

Which of the following is NOT used in experiments on attention to increase the attentional demands of a task?Question 15Answera.increasing the presentation rate of the stimuli shown to the participantb.increasing the time allowed for the participant to make a response to a stimulusc.increasing the number of stimuli to which the participant must attendd.increasing the complexity of the stimuli shown to the participant
