AppMonitor: A tool for recording user actions in unmodified Windows applications

This article describes AppMonitor, a Microsoft Windows-based client-side logging tool that records user actions in unmodified Windows applications. AppMonitor allows researchers to gain insights into many facets of interface interaction such as command use frequency, behavioral patterns prior to or following command use, and methods of navigating through systems and data sets. AppMonitor uses the Windows SDK libraries to monitor both low-level interactions, such as "left mouse button pressed" and "Ctrl-F pressed," as well as high-level "logical" actions, such as menu selections and scrollbar manipulations. The events recorded are configurable, allowing researchers to perform broad or targeted studies. No user input is required to manage logging, allowing participants to seamlessly conduct everyday work while their actions are monitored. The system currently supports logging in Microsoft Word and Adobe Reader; however, it could be extended for use with any Microsoft Windows-based application. To support other researchers wishing to create multilevel event loggers, we describe AppMonitor's underlying architecture and implementation, and provide a brief example of the data generated during our 4-month trial with six users.     

Structure and function in acquired prosopagnosia: Lessons from a series of 10 patients with brain damage

Acquired prosopagnosia varies in both behavioural manifestations and the location and extent of underlying lesions. We studied 10 patients with adult‐onset lesions on a battery of face‐processing tests. Using signal detection methods, we found that discriminative power for the familiarity of famous faces was most reduced by bilateral occipitotemporal lesions that involved the fusiform gyri, and better preserved with unilateral right‐sided lesions. Tests of perception of facial structural configuration showed severe deficits with lesions that included the right fusiform gyrus, whether unilateral or bilateral. This deficit was most consistent for eye configuration, with some patients performing normally for mouth configuration. Patients with anterior temporal lesions had better configuration perception, though at least one patient showed a more subtle failure to integrate configural data from different facial regions. Facial imagery, an index of facial memories, was severely impaired by bilateral lesions that included the right anterior temporal lobe and marginally impaired by fusiform lesions alone; unilateral right fusiform lesions tended to spare imagery for facial features. These findings suggest that (1) prosopagnosia is more severe with bilateral than unilateral lesions, indicating a minor contribution of the left hemisphere to face recognition, (2) perception of facial configuration critically involves the right fusiform gyrus and (3) access to facial memories is most disrupted by bilateral lesions that also include the right anterior temporal lobe. This supports assertions that more apperceptive variants of prosopagnosia are linked to fusiform damage, whereas more associative variants are linked to anterior temporal damage. Next, we found that behavioural indices of covert recognition correlated with measures of overt familiarity, consistent with theories that covert behaviour emerges from the output of damaged neural networks, rather than alternative pathways. Finally, to probe the face specificity of the prosopagnosic defect, we tested recognition of fruits and vegetables: While face specificity was not found in most of our patients, the data of one patient suggested that this may be possible with more focal lesions of the right fusiform gyrus.     

A novel assessment of behaviors associated with body dissatisfaction and disordered eating

The purpose of the present study was to compare response rates to questions assessing behaviors associated with body dissatisfaction and disordered eating on a standard self-report questionnaire that was nominally anonymous to an unmatched count questionnaire that allowed for true response anonymity. Five hundred sixty-seven undergraduate students were asked about disordered eating and body image-related behaviors using one of two response formats; either a conventional true-false questionnaire or an unmatched count questionnaire that did not require participants to directly respond to any sensitive questions. Both men and women had significantly different rates of endorsement between the two methods of assessment on the majority of the questions, suggesting that degree of anonymity and format of response may affect endorsements of these potentially sensitive topics. These results contribute to the existing literature highlighting the necessity of understanding self-report bias in determining accurate rates of sensitive behaviors.     

Examining the development of attention and executive functions in children with a novel paradigm.

The development of attention and executive functions in normal children (7-12 years) was investigated using a novel selective reaching task, which involved reaching as rapidly as possible towards a target, while at times having to ignore a distractor. The information processing paradigm allowed the measurement of various distinct dimensions of behaviour within a single task. The largest improvements in vigilance, set-shifting, response inhibition, selective attention, and impulsive responding were observed to occur between the ages of 8 and 10, with a plateau in performance between 10 and 12 years of age. These findings, consistent with a step-wise model of development, coincide with the observed developmental spurt in frontal brain functions between 7 and 10 years of age, and indicate that attention and executive functions develop in parallel. This task appears to be a useful research tool in the assessment of attention and executive functions, within a single task. Thus it may have a role in determining which cognitive functions are most affected in different childhood disorders.     

Initial Encounters of Young Men and Women: Impressions and Disclosure Estimates

The purpose of this study was to explore the expectation that, in conversations between unacquainted men and women, men would disclose more than women and would create a positive impression in so doing. In 8-min, relatively unstructured conversations, both men and women (N=301) perceived themselves and their partners as disclosing approximately the same amount. For both sexes, the more their partners disclosed, the more favorably they rated their partners on social attractiveness and positive attributes. Moreover, both sexes believed that the more they disclosed themselves, the more positively their partners evaluated them. However, the strength of this relationship was significantly stronger for men than for women. Neither sex conformed to the expectation that men should disclose more, but both may have believed to some extent that their partners were evaluating them in accord with this expectation.     

Psychosocial Variables as Predictors of Psychological Stress–Induced Ischemia in the Laboratory

This study examined ischemic reactivity to a psychological stress protocol and whether psychological variables could reliably classify individuals as ischemic reactors. Participants were 54 male Veterans Administration patients who had or were suspected of having CAD. Psychological inventories were administered prior to a psychological stress protocol consisting of a surgical video, the Stroop Color–Word task, an arithmetic task, and discussion of a stressful event. Cardiac functioning was evaluated using an ECG Holter monitor and 23.53% of participants were classified as reactors. Mean differences between reactors and nonreactors were found for State Anger, Health Locus of Control—Powerful Others (MHLC-PO), and Depression. State Anger and MHLC-PO emerged as significant predictors of reactor status in logistic regression analyses. Models based on individual scale items suggested three items could be used to achieve higher classification rates. Implications for revising screening procedures for determining risk and possible mechanisms underlying psychological stress–induced ischemia are discussed.
