The development of conflict resolution skills in kindergarten
An issue facing schools and educators today is that of children being desensitized to violence because of their many contact hours with the media (Carlsson-Paige & levin, 1992). Media becomes a powerful tool in the socialization process, when children are constantly exposed to the idea that violence is an acceptable and effective method of solving problems. When children are exposed to violent models for conflict resolution, whether firsthand or through the media, this becomes part of their repertoire of developed responses to conflict. Building on these responses, more violence is fostered. Other positive social responses that should be part of the child\u27s developing social cognition, are crowded out

The Federal Trust Responsibility and Treaty Protected Resources on Ceded Public Lands: A Huckleberry Case Study
Non-timber forest products (NTFPs) are an important aspect of the forest that has often been overlooked. NTFPs have been especially important to Native American people because of their subsistence, cultural, and economic values. As a result of their economic value, there have been an increased number of people harvesting NTFPs on public lands. In the Pacific Northwest, many Native American tribes have reserved treaty rights that guarantee that they can hunt fish and gather in usual and accustomed places. Many of these traditional food-gathering areas lie on what is now national forest land. As demand for NTFPs on public lands has increased, the U.S. Forest Service must find a way to reconcile its federal trust responsibility to the tribes with their responsibility to manage national forest lands for the general public. The research has focused on the ways in which the U.S. Forest Service (USFS) has gone about creating and implementing policies to fulfill the Trust responsibilities to the Tribes. Two case studies of treaty protected huckleberry harvests were conducted with two groups of Tribes and the associated National Forests where they exercise their treaty protected rights. The research involves an assessment of these policies and their implementation using two public policy frameworks: social construction and institutional rational choice. The majority of Forest Service offices in the Pacific Northwest have relied on informal agreements with the tribes to balance these responsibilities. Little formal policy has been created or implemented to manage user conflicts, and problems continue to plague NTFP management. These findings indicate that the USFS and the tribes need to find new ways of developing NTFP management policies that will satisfy tribal needs
Switch-independent task representations in frontal and parietal cortex
Alternating between two tasks is effortful and impairs performance. Previous fMRI studies have found increased activity in frontoparietal cortex when task switching is required. One possibility is that the additional control demands for switch trials are met by strengthening task representations in the human brain. Alternatively, on switch trials, the residual representation of the previous task might impede the buildup of a neural task representation. This would predict weaker task representations on switch trials, thus also explaining the performance costs. To test this, male and female participants were cued to perform one of two similar tasks, with the task being repeated or switched between successive trials. Multivoxel pattern analysis was used to test which regions encode the tasks and whether this encoding differs between switch and repeat trials. As expected, we found information about task representations in frontal and parietal cortex, but there was no difference in the decoding accuracy of task-related information between switch and repeat trials. Using cross-classification, we found that the frontoparietal cortex encodes tasks using a generalizable spatial pattern in switch and repeat trials. Therefore, task representations in frontal and parietal cortex are largely switch independent. We found no evidence that neural information about task representations in these regions can explain behavioral costs usually associated with task switching
Automatic and Controlled Processing: Implications for Eating Behavior
It is a widely held view that humans have control over their food choices and consumption. However, research also suggests that eating behavior is often triggered by contextual cues and guided by automaticities and habits. Interestingly, the dichotomy between automatic and controlled processing has recently been challenged, suggesting that they may be intertwined. In a large female sample (n = 567), we investigated the hypothesis that task-based and self-reported measures of automatic and controlled processing would interact and impact self-reported eating behavior. Results analyzed via structural equation modeling suggest that automatic, but not controlled processing, during a modified flanker task, including a context-specific proportion congruent (CSPC) manipulation, was inversely associated with self-reported self-control. The influence of self-control on unhealthy eating behavior (i.e., uncontrolled and emotional eating, heightened consumption of fat and sugar) was only indirect via habitual behavior, which itself had a strong direct impact. Unhealthy eating was further associated with real-life outcomes (e.g., body mass index (BMI)). Our findings suggest that eating behavior may indeed be guided primarily by automaticities and habits, whereas self-control might facilitate this association. Having self-control over eating might therefore be most effective by avoiding contextual cues eliciting undesired automatic behavior and establishing habits that serve long-term goals

Individual Differences in Goal Pursuit Despite Interfering Aversion, Temptation, and Distraction
Self-control can be defined as the ability to exert control over ones
impulses. Currently, most research in the area relies on self-report. Focusing
on attentional control processes involved in self-control, we modified a
spatial selective attentional cueing task to test three domains of self-
control experimentally in one task using aversive, tempting, and neutral
picture-distractors. The aims of the study were (1) to investigate individual
differences in the susceptibility to aversive, tempting, and neutral
distraction within one paradigm and (2) to test the association of these three
self-control domains to conventional measures of self-control including self-
report. The final sample consisted of 116 participants. The task required
participants to identify target letters “E” or “F” presented at a cued target
location while the distractors were presented. Behavioral and eyetracking data
were obtained during the performance of the task. High task performance was
encouraged via monetary incentives. In addition to the attentional self-
control task, self-reported self-control was assessed and participants
performed a color Stroop task, an unsolvable anagram task and a delay of
gratification task using chocolate sweets. We found that aversion, temptation,
and neutral distraction were associated with significantly increased error
rates, reaction times and gaze pattern deviations. Overall task performance on
our task correlated with self-reported self-control ability. Measures of
aversion, temptation, and distraction showed moderate split-half reliability,
but did not correlate with each other across participants. Additionally,
participants who made a self-controlled decision in the delay of gratification
task were less distracted by temptations in our task than participants who
made an impulsive choice. Our individual differences analyses suggest that (1)
the ability to endure aversion, resist temptations and ignore neutral
distractions are independent of each other and (2) these three domains are
related to other measures of self-control
Subliminal and supraliminal processing of reward-related stimuli in anorexia nervosa
Background. Previous studies have highlighted the role of the brain reward and cognitive control systems in the etiology of anorexia nervosa (AN). In an attempt to disentangle the relative contribution of these systems to the disorder, we used functional magnetic resonance imaging (fMRI) to investigate hemodynamic responses to reward-related stimuli presented both subliminally and supraliminally in acutely underweight AN patients and age-matched healthy controls (HC).
Methods. fMRI data were collected from a total of 35 AN patients and 35 HC, while they passively viewed subliminally and supraliminally presented streams of food, positive social, and neutral stimuli. Activation patterns of the group Ă— stimulation condition Ă— stimulus type interaction were interrogated to investigate potential group differences in processing different stimulus types under the two stimulation conditions. Moreover, changes in functional connectivity were investigated using generalized psychophysiological interaction analysis.
Results. AN patients showed a generally increased response to supraliminally presented stimuli in the inferior frontal junction (IFJ), but no alterations within the reward system. Increased activation during supraliminal stimulation with food stimuli was observed in the AN group in visual regions including superior occipital gyrus and the fusiform gyrus/parahippocampal gyrus. No group difference was found with respect to the subliminal stimulation condition and functional connectivity.
Conclusion. Increased IFJ activation in AN during supraliminal stimulation may indicate hyperactive cognitive control, which resonates with clinical presentation of excessive self-control in AN patients. Increased activation to food stimuli in visual regions may be interpreted in light of an attentional food bias in AN
