Echocardiographers can detect abnormalities accurately and rapidly from dynamic images. This is likely due to the application of cue-based associations resident in memory, a process known as cue utilization. This study investigated whether cue utilization is associated with the ability to apply within-domain capabilities (dynamic) to more degraded images (static). Fifty-eight echocardiographers completed the echocardiography edition of the Expert Intensive Skills Evaluation 2.0 (EXPERTise 2.0) to establish behavioral indicators of within-domain cue utilization. They also completed an abnormality detection and categorization task that comprised briefly presented static and moving images (50% abnormal). Behaviors consistent with higher cue utilization were associated with greater accuracy in detecting both static and dynamic images but not for categorization. This study provides important information about how experts who have the capacity to utilize cue-based strategies can rapidly and accurately detect abnormalities from domain-specific stimuli and generalize their skills to more challenging stimuli.

Driving is a high-risk and cognitively demanding activity that requires the efficient use of cognitive resources to inhibit responses when necessary to avoid accidents. Cue utilization, via an inherent capacity for pattern recognition, is one strategy that may be applied while driving to reduce cognitive load allowing for the allocation of resources to other demanding tasks. The present study was designed to measure the contribution of cue utilization in a driving context on performance in a response inhibition task. Undergraduate students (N = 105) completed the driving edition of EXPERTise 2.0 as an online assessment of cue utilization and a measure of response inhibition, the Stop-Signal Task. The results indicated that participants with relatively higher cue utilization were more accurate at inhibiting responses, but there was no difference in their response times. These findings provide support for cue utilization as one strategy that may improve response inhibition through the acquisition and recognition of patterns, thereby decreasing cognitive load. The practical implications for drivers will be discussed.

Echocardiographers are highly specialised, skilled practitioners who play a critical role in medical imaging diagnostics. Yet, little is known about the cognitive and perceptual attributes of experts within this domain. This study was designed to examine the role of individual differences in expertise. Specifically, the contribution of a domain general visual expertise and pattern recognition, or cue utilization. Data were collected from 42 echocardiographers and 43 naïve participants. All of the participants competed the Novel Object Memory Test (NOMT). When compared, the echocardiographers were more accurate than the naïve participants. The echocardiographers also completed an echocardiography edition of the Expert Intensive Skills Evaluation 2.0, to establish behavioral indicators of context-related cue utilization. Those with relatively higher cue utilization performed more accurately on the NOMT, controlling for exposure. These results suggest that a general perceptual ability contributes to echocardiography potential and a sensitivity to cue-based learning may contribute to expertise.
