Is your choice my choice? The owners’ effect on pet dogs’ (Canis lupus familiaris) performance in a food choice task

This study investigates the influence of owners on their dogs’ performance in a food choice task using either different or equal quantities of food. Fifty-four pet dogs were tested in three different conditions. In Condition 1 we evaluated their ability to choose between a large and small amount of food (quantity discrimination task). In Condition 2 dogs were again presented with a choice between the large and small food quantity, but only after having witnessed their owner favouring the small quantity. In Condition 3 dogs were given a choice between two equally small quantities of food having witnessed their owner favouring either one or the other. A strong effect of the owner on the dogs’ performance was observed. In Condition 1 dogs as a group chose significantly more often the large food quantity, thus showing their ability to solve the quantity discrimination task. After observing their owner expressing a preference for the small food quantity they chose the large quantity of food significantly less than in the independent choice situation. The tendency to conform to the owner’s choice was higher when the dogs had to choose between equally small quantities of food (Condition 3) rather than between a large and a small one (Condition 2). These results provide evidence that dogs can be influenced by their owners even when their indications are clearly in contrast with direct perceptual information, thus leading dogs to ultimately make counterproductive choices.     

Foraging and associative learning of visual signals in a parasitic wasp

To cope with environmental variability, animals should gather and use information to reduce uncertainty. In insect parasitoids, associative learning has been widely documented in the context of host foraging. However, despite its potential adaptive value, the insect food searching strategy and cues used to search are poorly understood. In this study, we examined the ability of hymenopteran Venturia canescens females to associate food to a visual cue. To broaden the scope of our results, experiments were performed with both arrhenotokous (sexual) and thelytokous (asexual) individuals. The wasps showed innate attraction for yellow and orange stimuli when presented versus blue stimuli. When trained to associate a food reward with one of the attractive colours (orange), they significantly moved from a distance towards the colour previously associated with food. The choice of the innately preferred colour (yellow) was not modified by associative learning. In the context of food foraging, this study is the first to show associative learning using visual stimuli in a parasitoid and active choice of this colour. This ability gives new insights concerning potential food sources for V. canescens in the field, since flowers are sugar sources, which emit colour signals.     

Potential Positive and Negative Consequences of Coresidence for Teen Mothers and their Children in Adult-Supervised Households

In 1996, part of the creation of TANF (Temporary Assistance for Needy Families) required minor teen parents to live in an adult-supervised household in order to receive cash assistance. This literature review discusses the positive and negative consequences of coresidence. Research has suggested that coresidence may be beneficial for the educational and financial success of teen mothers. However, there is some evidence that coresiding teen mothers have poorer parenting skills than teen mothers who do not coreside. Implications for policy implementation are discussed. Case managers should be aware of the possible risks of coresidence and weigh these risks against potential benefits. In addition, families of teen mothers, especially grandmothers, should be included in programming and interventions in order to provide positive living environments for teen mothers and their children.     

Perceived History of Anaphylaxis and Parental Overprotection,Autonomy, Anxiety,and Depression in Food Allergic Young Adults

This study examined autonomy, anxiety, depression, and perceptions of parental behavior in 86 food allergic young adults and 344 healthy young adults between the ages of 18 and 22. Participants completed an online survey measuring self-reported autonomy, anxiety, depression, and perceptions of parental behavior. Results indicated that, as a group, food allergic young adults did not differ from healthy peers. However, food allergic young adults who reported having experienced an anaphylactic reaction described their disease as more severe, reported more worry about their disease, and rated their parents as more overprotective than food allergic young adults who reported never having experienced anaphylaxis. The experience of anaphylaxis may be a reliable indicator of food allergic individuals who are at risk for psychological distress. A portion of this research was presented at the National Conference on Child Health Psychology in Miami, Fl in April, 2008.     

Biology is destiny only if we ignore it

Problems of sustainability and survivability are best met not with moralizing but with policies that take advantage of our increasingly understood evolved human psychology. This knowledge helps us understand why our problems recur, and why we need not expect them to have permanent solutions. What is needed is an evolutionary praxis. It is possible, for example, to create policies that work around our tendencies to hierarchize and to form into ethnocentric and mutually hostile groups. Although in many ways there may be a mismatch between our evolved human nature and contemporary society, the fact that it is we who construct our environments must reduce the extent of mismatch.     

The affective politics of policy making spaces: Gendered and racial embodiments of neoliberal deservingness and power in a city council meeting

Bringing together feminist works on affect, neoliberalism, and the racial dimensions of dependency discourse, this paper discusses affective politics in policy making spaces by examining a Durham (North Carolina, USA) City Council meeting. We focus on a 2017 Housing Needs Hearing where bodily gestures and speech acts were crucial parts of emotional interactions that defined, maintained, and challenged subject positions and power structures. We argue that embedded within legacies of racial and gender inequality, neoliberal sensibilities work through embodied emotional performances that impact policy conversations. Our analysis reveals how, despite progressive aspirations and accomplishments in Durham, the meeting's extractive set up perpetuates inequities by positioning those seeking assistance to prove their worth through a contradictory performance of desperation and self-actualization while enabling supporters of housing affordability, including city officials, to adopt the role of caring advocates. We find that a performance of pain and the rhetorical proof of self-responsibility opens up potential access to affordable housing and in doing so reveals both the limits and impact of a broken housing system. We thus extend analysis of the neoliberal condition of US housing inequality by deepening understanding of how neoliberal deservingness is embodied and shapes racialized, classed, and gendered subject positions.     

Individual Characteristics of Political Leaders and the Use of Analogy in Foreign Policy Decision Making

The linkages between individual characteristics of political leaders and their usage of historical analogy during foreign policy decision-making episodes were examined. The individual characteristics studied were conceptual complexity and policy expertise, while usage of analogy was studied in terms of the sophistication and source of historical comparisons. The great majority of the analogies used by low-complexity individuals were nonsophisticated, whereas high-complexity individuals consistently used more sophisticated analogies. Low-complexity individuals drew analogies solely from their own generational and cultural context, while high-complexity leaders drew their analogies from a wider range of sources. More expert leaders drew from their personal experiences to a marginally greater degree than less expert individuals but, interestingly, both types of individual relied on generally available rather than personally experienced events for their analogies. The value added of the approach is to demonstrate that different types of leaders use history differently during political decision making.     

The Ideological Legitimation of the Status Quo: Longitudinal Tests of a Social Dominance Model

Four studies examined whether members of the dominant group (New Zealand Europeans) who were high in Social Dominance Orientation (SDO) employed ideologies of equality-as-meritocracy to legitimate opposition toward policy-based resource allocations that favor disadvantaged groups. We tested this model, derived from Social Dominance Theory, using cross-sectional (Study 1; N =  338) and longitudinal data (Studies 2–4) collected in New Zealand. As predicted, SDO (but not Right-Wing Authoritarianism) exerted a cross-lagged effect on Equality Positioning and not vice-versa (Study 2; 1 year, N =  81); Equality Positioning exerted a cross-lagged effect on attitudes toward resource-specific social policies but not vice-versa (Study 3; 4 months, N =  132); and the cross-lagged effect of SDO on attitudes toward resource-specific policy was mediated longitudinally by Equality Positioning (Study 4; 1 year, N =  47). These findings indicate that the ideological positioning of equality is (at least partially) driven by individual differences in the motivation for group-based social dominance, and this in turn determines support for social and political policies that govern the group-based allocation of resources within society and thus systemic inequality.     

Testing VBN theory in Japan: Relationships between values,beliefs, norms,and acceptability and expected effects of a car pricing policy

The VBN (value-belief-norm) theory of environmentalism postulates that values influence pro-environmental behaviour via pro-environmental beliefs and personal norms. A few studies provided support for the theory in explaining pro-environmental behaviour in Europe and Latin America. Beyond these studies, the question remains to what extent the VBN theory can also explain pro-environmental beliefs, norms, and behaviour in other cultures. This study tests the VBN theory in Japan and demonstrates that, as expected, the more people endorse biospheric values, the stronger they believe that car use has negative environmental impacts, the more they feel responsible for the problems caused by car use, and the more they feel personally obliged to reduce their car use. In contrast, stronger hedonic and, to a lesser extent, stronger egoistic values were related to less strong pro-environmental beliefs and norms. Furthermore, support was found for the mediation effects of pro-environmental beliefs in the relationships between hedonic and biospheric value orientations and norms. The VBN theory explained the acceptability and expected effects of a car pricing policy on an individual’s transport choices, but less strongly than in previous studies. Interestingly, biospheric and hedonic values not only predicted adjacent beliefs, but also other beliefs and norms farther down the causal chain, suggesting that values play an important role in promoting sustainable mobility.
