Countermanding Task

The countermanding paradigm provides a useful tool for examining the mechanisms responsible for canceling eye movements. The key feature of this paradigm is that, on a minority of trials, a stop signal is introduced some time after the appearance of the target, indicating that the subject should cancel the incipient eye movement. If the delay in giving the stop signal is too long, subjects fail to cancel the eye movement to the target stimulus. By modeling this performance as a race between a go process triggered by the appearance of the target and a stop process triggered by the appearance of the stop signal, it is possible to estimate the processing interval associated with canceling the movement. We have now used this paradigm to analyze the canceling of pursuit and saccades. For pursuit, we obtained consistent estimates of the stop process regardless of our technique or assumptions—it took 50–60 ms to cancel pursuit in both humans and monkeys. For saccades, we found different values depending on our assumptions. When we assumed that saccade preparation was under inhibitory control up until movement onset, we found that saccades took longer to cancel (humans: ∼110, monkeys: ∼80 ms) than pursuit. However, when we assumed that saccade preparation includes a final “ballistic” interval not under inhibitory control, we found that the same rapid stop process that accounted for our pursuit results could also account for the canceling of saccades. We favor this second interpretation because canceling pursuit or saccades amounts to maintaining a state of fixation, and it is more parsimonious to assume that this involves a single inhibitory process associated with the fixation system, rather than two separate inhibitory processes depending on which type of eye movement will not be made. From our behavioral data, we estimate that this ballistic interval has a duration of 9–25 ms in monkeys, consistent with the known physiology of the final motor pathways for saccades, although we obtained longer values in humans (28–60 ms). Finally, we examined the effect of trial sequence during the countermanding task and found that pursuit and saccade latencies tended to be longer if the previous trial contained a stop signal than if it did not; these increases occurred regardless of whether the preceding trial was associated with the same or different type of eye movement. Together, these results suggest that a common inhibitory mechanism regulates the initiation of pursuit and saccades.

We investigated whether individual differences in inhibitory control relate to bilingual spoken word recognition. While their eye movements were monitored, native English and native French English–French bilinguals listened to English words (e.g., field) and looked at pictures corresponding to the target, a within-language competitor (feet), a French cross-language competitor (fille “girl”), or both, and unrelated filler pictures. We derived cognitive and oculomotor inhibitory control measures from a battery of inhibitory control tasks. Increased cognitive inhibitory control was linked to less within-language competition for all bilinguals, and less cross-language competition for native French low-English-exposure bilinguals. Increased oculomotor inhibitory control was linked to less within-language competition for all native French bilinguals, and less cross-language competition for native French low-English-exposure bilinguals. The results extend previous findings (Blumenfeld & Marian, 2011), and suggest that individual differences in inhibitory control relate to bilingual spoken word processing.

Some characteristics of saccadic eye movements were investigated electro-oculographically in hemiplegic attentionally handicapped patients and normal subjects under stationary and moving target situations. The velocity of saccadic eye movements was greater and the duration shorter in hemiplegic than in normal subjects. Greater variability of angular velocity and amplitude functions, and of duration and amplitude functions was found among hemiplegic subjects than among normal. The results were explained, in part, by possible differences in the strength of extra-ocular muscle contraction, variables associated with inhibitory control and learning variables.

Task Irrelevant

Previous research has shown that during visual search young and old adults' eye movements are equivalently influenced by the appearance of task-irrelevant abrupt onsets. The finding of age-equivalent oculomotor capture is quite surprising in light of the abundant research suggesting that older adults exhibit poorer inhibitory control than young adults on a variety of different tasks. In the present study, we examined the hypothesis that oculomotor capture is age invariant when subjects' awareness of the appearance of task-irrelevant onsets is low, but that older adults will have more difficulty than young adults in inhibiting reflexive eye movements to task-irrelevant onsets when awareness of these objects is high. Our results were consistent with the level-of-awareness hypothesis. Young and old adults showed equivalent patterns of oculomotor capture with equiluminant onsets, but older adults misdirected their eyes to bright onsets more often than young adults did.
