    Abstract: A 43-year-old professional skateboarder presented to the sports medicine clinic with complaints of left wrist pain to the ulnar aspect. Two weeks prior to presentation, his wrist became suddenly painful with no specific trauma. He reported a history of falls over the years while skateboarding but none directly correlated to his onset of wrist pain. Radiographic results were negative for wrist or hand fracture. Physical examination yielded tenderness and mild swelling to the ulnar aspect of the wrist. Musculoskeletal ultrasound was used to assess tendon and ligament integrity, all of which was intact. Both radial and ulnar arteries were visualized, and ulnar artery thrombosis was incidentally diagnosed. He was advised to immediately proceed to the hospital, where an open arthrectomy was performed to the ulnar artery the following day. The patient was released from the hospital 2 days later and subsequently made a full recovery.

    Abstract: Expand research on the Sustained Attention to Response Task (SART) to a more applied agricultural target detection/selection task and examine the utility of various performance metrics, including composite measures of speed and accuracy, in a High-Go/Low-No-Go stimuli task. Background Modified SARTs have been utilized to investigate mechanisms, such as failures of response inhibition, occurring in friendly fire and collateral damage incidents. Researchers have demonstrated that composite measures of speed and accuracy are useful for Low Go/High No-Go stimuli tasks, but this has not been demonstrated for High-Go/Low-No-Go tasks, such as the SART. Method Participants performed a modified SART, where they selected (“sprayed”) images of weeds (Go stimuli) that appeared on a computer screen, while withholding to rarer soybean plant images (No-Go stimuli). Results Response time was a function of distance from a central starting point. Participants committed commission errors (sprayed the soybeans) at a significantly higher rate when the stimuli appeared under the cursor centered on the screen for each trial. Participant’s omission errors (failure to spray a weed) increased significantly as a function of distance. The composite measures examined were primarily influenced by response time and omission errors limiting their utility when commission errors are of particular interest. Conclusion Participants are far more accurate in their decision making when required to execute a longer duration motor task in High-Go/Low-No-Go experiments. Application Demonstrates a serious human factors liability of target detection and snap-to-target systems.

    How Much Memory Does Oculomotor Search Have?

    Abstract: Research has demonstrated that oculomotor visual search is guided by memory for which items or locations within a display have already been inspected. In the study reported here, we used a gaze-contingent search paradigm to examine properties of this memory. Data revealed a memory buffer for search history of three to four items. This buffer was effected in part by a space-based trace attached to a location independently of whether the object that had been seen at that position remained visible, and was subject to interference from other stimuli seen in the course of a trial.

    Abstract: By monitoring subjects' eye movements during a visual search task, we examined the possibility that the mechanism responsible for guiding attention during visual search has no memory for which locations have already been examined. Subjects did reexamine some items during their search, but the pattern of revisitations did not fit the predictions of the memoryless search model. In addition, a large proportion of the refixations were directed at the target, suggesting that the revisitations were due to subjects' remembering which items had not been adequately identified. We also examined the patterns of fixations and compared them with the predictions of a memoryless search model. Subjects' fixation patterns showed an increasing hazard function, whereas the memoryless model predicts a flat function. Lastly, we found no evidence suggesting that fixations were guided by amnesic covert scans that scouted the environment for new items during fixations. Results do not support the claims of the memoryless search model, and instead suggest that visual search does have memory.

    SAGE Publications ; 2015

    Abstract: The authors determine whether transcranial direct current stimulation (tDCS) can reduce resumption time when an ongoing task is interrupted. Background: Interruptions are common and disruptive. Working memory capacity has been shown to predict resumption lag (i.e., time to successfully resume a task after interruption). Given that tDCS applied to brain areas associated with working memory can enhance performance, tDCS has the potential to improve resumption lag when a task is interrupted. Method: Participants were randomly assigned to one of four groups that received anodal (active) stimulation of 2 mA tDCS to one of two target brain regions, left and right dorsolateral prefrontal cortex (DLPFC), or to one of two control areas, active stimulation of the left primary motor cortex or sham stimulation of the right DLPFC, while completing a financial management task that was intermittently interrupted with math problem solving. Results: Anodal stimulation to the right and left DLPFC significantly reduced resumption lags compared to the control conditions (sham and left motor cortex stimulation). Additionally, there was no speed-accuracy tradeoff (i.e., the improvement in resumption time was not accompanied by an increased error rate). Conclusion: Noninvasive brain stimulation can significantly decrease resumption lag (improve performance) after a task is interrupted. Application: Noninvasive brain stimulation offers an easy-to-apply tool that can significantly improve interrupted task performance.

    Abstract: Theories accounting for the process of primary task resumption following an interruption have focused on the suspension and retrieval of a specific goal (Altmann & Trafton, 2002). The ability to recall the spatial location of where in the task one was prior to being interrupted may also be important. We show that being able to maintain a spatial representation of the primary task facilitates task resumption. Participants were interrupted by an instant message window that either partially or fully occluded the primary task interface. Reaction time measures show that participants were faster at resuming in the partial occlusion condition. In addition, eye track data suggest that participants were more accurate at returning to where they left off, suggesting that they were able to maintain a spatial representation of the task and use this information to resume more quickly.

    Abstract: The present study examined rats' responding on a differential-reinforcemenr-of-low-rates schedule of food reinforcement following intraperitoneal injections of various doses of bombesin (4, 6, 8, 16, 32 μg/kg). Analyses indicated that only the 6 μg/kg dosage improved DRL responding. The findings are consistent with prior research examining bombesin's effect on operant behavior and support the notion that bombesin induces satiety rather than malaise.

    Abstract: Interruptions research has generally focused on the factors that make interruptions more or less disruptive to primary task performance, the ways in which people engage the interruption as they disengage from a primary task, and the role of environmental context/cues in primary task resumption. However, little research has focused on investigating the processes by which a person reorients to and resumes the primary task following an interruption. This research explores the potential roles of spatial location and goal memory in the process of resumption. The experiment reported uses a new paradigm in which, following an interruption, a person can be returned to a different task and/or a different location. We found that both goal memory and spatial memory play a role in resuming the primary task following an interruption. However, there is still not a clear picture of how the two interact, and it may be that individual differences play an important role in how people deal with interruptions.

    Abstract: Working memory capacity (WMC) is generally referred to as a quantitative measure of the ability to maintain relevant information while performing unrelated tasks (Delaney & Sahakyan, 2007). Although studies have shown that WMC can vary by individual (Engle et al., 1992; Just, 1992), performance can be taxed by varying degrees of subjective workload depending on the task parameters. Most studies have shown task performance benefits for individuals with high working memory capacity, with some exceptions for individuals with low working memory capacity (Barrett, Tugade, & Engle, 2004; Kane et al, 2001; Beilock et al, 2005). Kane and colleagues (2006) tested the relationship of WMC and executive attention control and found no relationship with individual differences in WMC and performance on visual search tasks, namely on feature-absence, conjunction, and spatial configuration search tasks. However, other studies have found that loading working memory interferes with search (Peterson, Beck & Wong, 2008; Han & Kim, 2004; He & McCarley, 2010). To explore how WMC affects visual search performance, a study is proposed to test whether the use of a complex visual search task can demonstrate a relationship between WMC and visual search performance. It is hypothesized that a visual search task aimed at engaging the control of attention and limiting automatic forms of information processing will be performed better by high WMC individuals compared to low WMC individuals. The implications of this proposal would help in designing for cockpit operation, driving, or other operations that require effortful control where the contributions and limitations of an individual's working memory capacity should be considered.

    Abstract: To assess plasma zinc and copper concentration in individuals with autism and correlate these levels with symptom severity. Subjects and Methods Plasma from 102 autistic individuals, and 18 neurotypical controls, were tested for plasma zinc and copper using inductively-coupled plasma-mass spectrometry. Copper and zinc levels and Cu/Zn were analyzed for possible correlation with severity of 19 symptoms. Results Autistic individuals had elevated plasma levels of copper and Cu/Zn and lower, but not significantly lower, plasma Zn compared to neurotypical controls. There was a correlation between Cu/Zn and expressive language, receptive language, focus attention, hyperactivity, fine motor skills, gross motor skills and Tip Toeing. There was a negative correlation between plasma zinc concentration and hyperactivity, and fine motor skills severity. Discussion These results suggest an association between plasma Cu/Zn and severity of symptoms associated with autism.
