Physicians,battery, and the duty to give informed consent

This essay discusses the issue of informed consent as it relates not only to physician duty but also to patient duty. The author is particularly concerned with the possibility of battery charges against the physician unless a clear patient duty is articulated. In summary, the author concludes that we can prevent doctors from being forced to commit battery in a way which allows them to make reasonable choices for their patients without being open to the charge of having committed battery. At the same time, we would not allow doctors to abuse this privelege.     

Hippocampus lesions impair landmark array spatial learning in homing pigeons: a laboratory study

Hippocampal (HF)-lesioned pigeons display impaired homing ability when flying over familiar terrain, where they are presumably relying on a map-like representation of familiar landmarks to navigate. However, research carried out in the field precludes a direct test of whether hippocampal lesions compromise the ability of homing pigeons to navigate by familiar landmarks. To examine more thoroughly the relationship between hippocampus and landmark spatial learning, control, neostriatum-lesioned, and HF-lesioned homing pigeons were trained on two open field, laboratory, conditional discrimination tasks. One was a visual landmark array task, and the other was a room color discrimination task. For the tasks, the correct of three differently colored food bowls was determined by the spatial relationship among a group of five landmarks and room color, respectively. Intact control birds successfully learned both tasks, while neostriatum-lesioned birds successfully learned the landmark array task-the only task on which they were trained. By contrast, HF-lesioned birds successfully learned the room color task but were unable to learn the landmark array task. The data support the hypothesis that homing performance deficits observed in the field following hippocampal lesions are in part a consequence of an impairment in the ability of lesioned pigeons to use familiar visual landmarks for navigation.     

The Relationship Between Creativity and Attention in Adults

Creativity is a valuable attribute that involves the generation of original ideas; attention is a vital function that facilitates information selection. There is some evidence that creative people may have poorer attention and are generally more distracted than others, and this distractibility is thought to enable the production of novel ideas. Previous research has largely supported this relationship between creativity and attention, yet they are both multifaceted constructs that can be measured in numerous ways. Using multiple measures of each construct, the aim of this study was to examine which features of creativity and attention might be related in a group of 100 adults (18–80 years, M = 26.9, SD = 11.5). Figural divergent-thinking (DT) originality was positively related to self-reported concentration; yet no other relationships were found. Results suggest that there is no consistent relationship between creativity and attention, and past studies that linked creativity to attention, having used just one or two measures, may be premature in their conclusions.     

The Role of Trait Anger in the Relationship between Stressors and Counterproductive Work Behaviors: Convergent Findings from Multiple Studies and Methodologies

Across three studies, we investigated the moderating role of trait anger in the relationship between workplace stressors and counterproductive work behaviors (CWB). In Study 1, all the variables were measured using self‐reports. In Study 2, workplace stressors were measured using co‐worker reports, trait anger was measured using significant other reports, and CWB was measured using self‐reports. In Study 3, we measured workplace stressors at Time 1, trait anger at Time 2 (6 months later), and objective indicators of CWB at Time 3 (12 months after Time 2). Convergent results were obtained across the three studies, with positive associations between workplace stressors and CWB, trait anger and CWB, and with trait anger moderating the relationship between stressors and CWB.
