AbstractConsistent inter-individual variation within a population, widely referred to as personality variation, can be affected by environmental context. Feedbacks between an individual’s personality and state can strengthen (positive feedback) or weaken (negative feedback) individual differences when experiences such as predator encounters or winning contests are dependent on personality type. We examined the influence of foraging on individual-level consistency in refuge use (a measure of risk-taking, i.e. boldness) in three-spined sticklebacks, Gasterosteus aculeatus, and particularly whether changes in refuge use depended on boldness measured under control conditions. In the control treatment trials with no food, individuals were repeatable in refuge use across repeated trials, and this behavioral consistency did not differ between the start and end of these trials. In contrast, when food was available, individuals showed a higher degree of consistency in refuge use at the start of the trials versus controls but this consistency significantly reduced by the end of the trials. The effect of the opportunity to forage was dependent on personality, with bolder fish varying more in their refuge use between the start and the end of the feeding trials than shyer fish. This suggests a state-behavior feedback, but there was no overall trend in how individuals changed their behavior, with some individuals spending more, and others less, time in the refuge area at the end than at the start of the trials. Our study shows that personality variation can be suppressed in foraging contexts and a potential but unpredictable role of feedbacks between state and behavior.

Abstract Consistent inter-individual variation in behaviour within a population, widely referred to as personality variation, can be affected by environmental context. Feedbacks between an individual’s behaviour and state can strengthen (positive feedback) or weaken (negative feedback) individual differences when experiences such as predator encounters or winning contests are dependent on behavioural type. We examined the influence of foraging on individual-level consistency in refuge use (a measure of risk-taking, i.e. boldness) in three-spined sticklebacks, Gasterosteus aculeatus, and particularly whether changes in refuge use depended on boldness measured under control conditions. In the control treatment trials with no food, individuals were repeatable in refuge use across repeated trials, and this behavioural consistency did not differ between the start and end of these trials. In contrast, when food was available, individuals showed a higher degree of consistency in refuge use at the start of the trials versus controls but this consistency significantly reduced by the end of the trials. The effect of the opportunity to forage was dependent on behavioural type, with bolder fish varying more in their refuge use between the start and the end of the feeding trials than shyer fish, and boldness positively predicted the likelihood of feeding at the start but not at the end of the trials. This suggests a state-behaviour feedback, but there was no overall trend in how bolder individuals changed their behaviour. Our study shows that personality variation can be suppressed in foraging contexts and a potential but unpredictable role of feedbacks between state and behaviour. Significance statement In this experimental study, we examined how foraging influences consistency in risk-taking in individual three-spined sticklebacks. We show that bolder individuals become less consistent in their risk-taking behaviour than shyer individuals during foraging. Some bolder individuals reinforce their risk-taking behaviour, suggesting a positive feedback between state and behaviour, while others converge on the behaviour of shyer individuals, suggesting a negative feedback. In support of a role of satiation in driving negative feedback effects, we found that bolder individuals were more likely to feed at the start but not at the end of the trials. Overall, our findings suggest that foraging can influence personality variation in risk-taking behaviour; however, the role of feedbacks may be unpredictable.

Research on attitudinal ambivalence started in the early 1970s, forty years after the first wave of research on attitudes. Ambivalent attitudes consist of both positive and negative evaluations of the same object. Early approaches proposed different measurement methods, and ambivalence can now be measured either directly (referred to as “felt ambivalence”) or indirectly (referred to as “potential ambivalence”). Because of its duality, ambivalence has been studied in comparison with univalent attitudes—which consist of either positive or negative evaluations of an object—to uncover their specific features, antecedents, and consequences. Relevant research has focused on identifying the prevalence of ambivalent attitudes, and on whether they could stem from particular personality traits or situations. Researchers have found that ambivalent attitudes seem to be widespread and can be held for a long period of time. Their relationship with behaviors has also been widely studied. At the individual level, ambivalence increases response latency when a choice has to be made, extends information processing, can affect attitude stability, and can even lead to discomfort. At the behavioral level, studies have highlighted the moderating role of attitudinal ambivalence on the relationship between attitudes and behavior. A different field of research focuses on its strength to question whether ambivalence leads to more resistance or susceptibility to persuasion and influence. It appears that ambivalent attitudes are pliable and, depending on the context, can either help individuals to be more adaptive or prevent them from arriving at a satisfying conclusion. The role of ambivalent attitudes in interpersonal relationships and self-presentation also highlight some benefits in holding an ambivalent attitude. This article opens by reviewing general overviews to provide a detailed picture of the current state of research. It then presents early approaches to attitudinal ambivalence, and reviews studies that highlight the moderating role of attitudinal ambivalence on the relationship between attitudes and behavior, as well as studies that question whether ambivalence might lead to more resistance or susceptibility to persuasion and influence. The article then focuses on the impact of ambivalence at the individual level. Antecedents of attitudinal ambivalence will be reviewed, as well as its consequences on the individual. The article concludes by presenting research questioning its functions as well as some applied work.

The name similarity effect is the tendency to like people, places, and things with names similar to our own. Although many researchers have examined name similarity effects on preferences and behavior, no research to date has examined whether individual differences exist in susceptibility to those effects. This research reports the results of two experiments that examine the role of self-monitoring in moderating name similarity effects. In the first experiment, name similarity effects on brand attitude and purchase intentions were found to be stronger for respondents high, rather than low, in self-monitoring. In the second experiment, the interactive effect observed in the first study was found to be especially true in a public (vs. private) usage context. These findings are consistent with theoretical expectations of name similarity effects as an expression of egotism manifested in the image and impression management concerns of high self-monitors.

One of the environmental problems in urban areas is the pollution caused by garbage. The waste problem is caused by various factors such as population growth, living standards changes, lifestyles and behavior, as well as how the waste management system. This study aims to determine how the role of society to levy payments garbage in Samarinda. This research was descriptive; where the data is collected then compiled, described and analyzed used relative frequency analysis. The participation of the public to pay a "levy junk", which stated to pay 96.67%, for each month and the rates stated society cheap, moderate and fairly, respectively 46.08%, 21.21%, 21.04%. Base on the data , the role of the community to pay "levy junk" quite high.
