Achievement Goal Orientations,Perceived Ability,and Sportspersonship in Youth Soccer

The present study was designed to examine the contribution of goal orientations and the influence of perceived ability as a moderating factor in predicting sportspersonship in competitive youth soccer. Participants were 511 Norwegian male youth soccer players, from ages 13 to 16, participating in the Norway Cup International Football Tournament. Findings revealed that high task-oriented participants consistently endorsed sportspersonship. However, participants who were high in ego orientation and high in task orientation only partially endorsed low sportspersonship. Perceived ability was a significant factor in that players high in ego orientation and low in perceived ability expressed the lowest respect for rules and officials and endorsed cheating behavior to reach their goals. In contrast, participants high in perceived ability and low in ego orientation expressed the highest level of respect for rules and officials. In this study, being high or low in ego orientation had a significant effect on sportspersonship.     

Screening for Muir-Torre Syndrome Using Mismatch Repair Protein Immunohistochemistry of Sebaceous Neoplasms

Screening for the Muir-Torre variant of Lynch Syndrome (LS) using Mismatch Repair (MMR) gene immunohistochemistry (IHC) on sebaceous neoplasms (SNs) is technically feasible. To date, research into the clinical utility of MMR IHC for this indication is limited. We conducted a retrospective chart review of 90 patients with MMR IHC completed on at least one SN from January 2005 to May 2010. SNs included were adenomas, epitheliomas, carcinomas and basal and squamous cell carcinomas with sebaceous differentiation. Of the 90 patients, 13 (14 %) had genetically confirmed or fulfilled clinical criteria for a diagnosis of MTS and 51 patients (57 %) presented with an abnormal MMR IHC result (loss of one or more MMR proteins) on at least one SN. Abnormal IHC had a sensitivity of 85 %, specificity of 48 %, positive predictive value (PPV) of 22 % and negative predictive value (NPV) of 95 % when evaluating for MTS. When personal or family history of colorectal cancer (≥2 family members with a history of colorectal cancer) was taken into consideration, ignoring IHC results, sensitivity was 92 %, specificity was 99 %, PPV was 92 % and NPV was 99 %. MMR IHC on SNs when used to screen for MTS has poor diagnostic utility. We recommend that MMR IHC not be performed routinely on SNs when the patient does not have either personal or family history of colorectal cancer.     

The Impact of Strategic Trajectory Optimization on Illusory Target Biases During Goal-Directed Aiming

During rapid aiming, movements are planned and executed to avoid worst-case outcomes that require time and energy to correct. As such, downward movements initially undershoot the target to avoid corrections against gravity. Illusory target context can also impact aiming bias. Here, the authors sought to determine how strategic biases mediate illusory biases. Participants aimed to Müller-Lyer figures in different directions (forward, backward, up, down). Downward biases emerged late in the movement and illusory biases emerged from peak velocity. The illusory effects were greater for downward movements at terminal endpoint. These results indicate that strategic biases interact with the limb-target control processes associated with illusory biases. Thus, multiple control processes during rapid aiming may combine and later affect endpoint accuracy (D. Elliott et al., 2010 Elliott, D., Hansen, S., Grierson, L. E. M., Lyons, J., Bennett, S. J., &; Hayes, S. J. (2010). Goal-directed aiming: two components but multiple processes. Psychological Bulletin, 136, 1023–1044.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]).     

An MMPI Comparison of Two Groups of Institutionalized Delinquents

Two independent studies compared the MMPI performance of 2 groups of matched institutionalized delinquent boys, those who caused trouble in dormitories (SSs) and those who did not (GGs). In the 1st study, Scale 4 was the only statistically significant scale. Cross-validation found no scales statistically significant. Nineteen items which discriminated between SSs and GGs in the 1st study did not hold up in the cross-validation study. It is concluded that the MMPI has questionable value in discriminating between different levels and types of delinquents.     

Memory and Perceptual Trace Development in Ballistic Timing

Adams’ (1971) closed-loop theory holds that memory and perceptual trace development is a function of the amount of practice with knowledge of results. If knowledge of results is withdrawn before these two memory states are strong performance will worsen, but after substantial practice performance can be maintained and evaluated in the absence of knowledge of results. To test the first prediction, three independent groups were given varying amounts of KR trials prior to early knowledge of results withdrawal. Subjects attempted to produce a 24.13-cm movement in exactly 150 msec. Memory and perceptual trace performance (as reflected in mean absolute and mean absolute estimated error, respectively) were dependent on the amount of knowledge of results practice, and the memory and perceptual trace remained reasonably strong during late knowledge of results withdrawal.     

Job Stress and Dyadic Synchrony in Police Marriages: A Preliminary Investigation

Despite reports documenting adverse effects of stress on police marriages, few empirical studies focus on actual emotional behaviors of officers and spouses. In this preliminary investigation, 17 male police officers and their nonpolice wives completed daily stress diaries for 1 week and then participated in a laboratory‐based discussion about their respective days. Conversations were video‐recorded and coded for specific emotional behaviors reflecting hostility and affection, which are strong predictors of marital outcomes. We examined associations between officers' job stress (per diaries and the Police Stress Survey) and couples' emotional behavior (mean levels and behavioral synchrony) using a dyadic repeated measures design capitalizing on the large number of observations available for each couple (1020 observations). When officers reported more job stress, they showed less hostility, less synchrony with their wives' hostility, and more synchrony with their wives' affection; their wives showed greater synchrony with officers' hostility and less synchrony with officers' affection. Therefore, for officers, greater job stress was associated with less behavioral negativity, potentially less attunement to wives' negativity, but potentially greater attunement to wives' affection—perhaps a compensatory strategy or attempt to buffer their marriage from stress. These attempts may be less effective, however, if, as our synchrony findings may suggest, wives are focusing on officers' hostility rather than affection. Although it will be important to replicate these results given the small sample, our findings reveal that patterns of behavioral synchrony may be a key means to better understand how job stress exacts a toll on police marriages.
