Goats Favour Personal Over Social Information In An Experimental Foraging Task, Luigi Baciadonna, Alan G. Mcelligott, Elodie F. Briefer

Elodie Briefer, PhD

Animals can use their environments more efficiently by selecting particular sources of information (personal or social), according to specific situations. Group-living animals may benefit from gaining information based on the behaviour of other individuals. Indeed, social information is assumed to be faster and less costly to use than personal information, thus increasing foraging efficiency. However, when food sources change seasonally or are randomly distributed, individual information may become more reliable than social information. The aim of this study was to test the use of conflicting personal versus social information in goats (Capra hircus), in a foraging task.We found that goats …

Department of Communication Studies: Faculty Publications

Objective: The aim of this study was to examine the decision-making (DM) styles of younger (18-39 years), middle-aged (40-59 years), and older (≥60 years) cancer survivors, the type and role of social support, and patient satisfaction with cancer treatment DM.

Method: Adult cancer survivors (N = 604) were surveyed using Qualtrics online software.

Results: Older adults reported significantly lower influence of support on DM than younger adults. The most common DM style for the age groups was collaborative DM with their doctors. Younger age was a significant predictor of independent (p < .05), collaborative with family (p < .001), delegated to doctor (p < .01), delegated to family (p < .001), and demanding (p < .001) DM styles.

Discussion: Despite having lower received social support in cancer …

Decision-Making Processes, Driving Performance, And Acute Responses To Alcohol In Dui Offenders, Walter Roberts

Theses and Dissertations--Psychology

Alcohol-impaired driving is a major cause of motor vehicle accident and death in the United States. People who are arrested for DUI (Driving under the Influence) are at high risk to reoffend; approximately one in three of these individuals will commit another DUI offense in the three years following their first conviction (Nochajski & Stasiewicz, 2006). This high risk for recidivism in these individuals suggests that cognitive characteristics may contribute to a pattern of pathological decision making leading to impaired driving. Indeed, individuals with a history of DUI report higher rates of impulsiveness and behavioral dysregulation compared to their nonoffending …

Measurement Challenges In Shared Decision Making: Putting The ‘Patient’ In Patient‐Reported Measures, Paul J. Barr, Glyn Elwyn

Dartmouth Scholarship

Measuring clinicians' shared decision-making (SDM) performance is a key requirement given the intensity of policy interest in many developed countries - yet it remains one of the most difficult methodological challenges, which is a concern for many stakeholders. In this Viewpoint Article, we investigate the development of existing patient-reported measures (PRMs) of SDM identified in a recent review. We find that patients were involved in the development of only four of the 13 measures. This lack of patient involvement in PRM development is associated with two major threats to content validity, common to all 13 PRMs of SDM: (i) an …
