On the emergence of deprivation-reducing behaviors: Subliminal priming of behavior representations turns deprivation into motivation

Building on recent research into the emergence of human motivation and goal pursuit in the absence of the conscious awareness of the source of this pursuit, the present article aimed to shed light on how states of deprivation (e.g., deprivation of fluid) actually produce the motivation and corresponding behavior that lifts the deprivation. Two studies established that when participants were relatively deprived of fluids, they experienced enhanced motivation to drink and consumed more fluid in an alleged tasting test, and these effects were more pronounced when the concept of drinking was rendered accessible by subliminal priming. These results suggest that specific motivational goal states and corresponding behaviors do not arise directly from deprivation per se, but that accessible goal-related cognitions play a role in this process. Implications for theory and research on deprivation and non-conscious goal pursuit are briefly discussed.     

Nonconscious goal pursuit and the surmounting of physical and social obstacles

The ability to overcome obstacles is widely regarded as a sign of motivation. Building on recent research on nonconscious goal pursuit, two experiments are presented that test whether activating the goal of helping outside people's awareness by exposure to social stereotypes causes them to overcome physical and social obstacles. Experiment 1 established that although overall participants were less inclined to pick up a tissue that was accidentally dropped on the floor by the experimenter when this tissue was dirty instead of clean, they were able to overcome their aversion toward picking up the physical object when they were primed with the mental representation of a social group (e.g., nurse) containing the goal of helping. Results were replicated in Experiment 2, in which participants had to overcome a social obstacle by providing feedback to a student of a negatively evaluated ethnic minority group, and explanations in terms of demand characteristics and mood were excluded. Implications for the literature on nonconscious goal pursuit are briefly discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

The Lost Voice: How Libertarianism and Consumerism Obliterate the Need for a Relational Ethics in the National Health Care Service

This article analyzes the contribution Christian ethics mightbe able to make to the ethical debate on policy and caregivingin health and social care in the United Kingdom. The articledeals particularly with the concepts of solidarity and subsidiaritywhich are essential in Christian social ethics and health careethics, and which may be relevant for the ethical debate onhealth and social caregiving in the United Kingdom. An importantargument in the article is that utilitarian and market-drivenpolicies in the National Health Service (NHS) and the socialcare system have marginalized the position of the elderly andhave seriously impoverished the quality of care for the elderly.The neglect of the elderly and other vulnerable groups is alsothe result of widespread consumerist attitudes among patientsand of libertarian models of noninterference which are affirmedby a public ethos of self-sufficiency and counter-dependency.Those who need care dare not make their need known to othersand ask for help, while simultaneously those who could helpare so intimidated by the public affirmation of privacy andnegative rights that they do not dare to offer help except ifthis is explicitly demanded. This distant and standoffish attitudeis in an important way responsible for the fact that the voiceof those in need is altogether lost to the public forum. Christianethics puts much emphasis on responsibility and solidarity withthe needy other but is not able to have much impact on the deliveryof care in a secularized society and health care system likethe NHS. Nonetheless, Christianity still has a powerful andrespected voice, by speaking up for those who cannot speak forthemselves, such as the elderly and the handicapped. Christianscan find allies in the ethics of care and other relational approachesin health care ethics in order to combat libertarianism, consumerism,and utilitarianism.     

Learning in cod (Gadus morhua): long trace interval retention

Basic knowledge about learning capacities and awareness in fish is lacking. In this study we investigated which temporal gaps Atlantic cod could tolerate between two associated events, using an appetitive trace-conditioning paradigm with blinking light as conditioned stimulus (CS) and dry fish food as unconditioned stimulus (US). CS–US presentations were either temporally overlapping (delay conditioning, CS duration 24 s, interstimulus interval 12 s) or separated by 20, 60, or 120 s (trace conditioning, CS duration 12 s) or 2 h (control, CS duration 12 s). The percentage of fish in the feeding area increased strongly during CS presentation in all delay, 20 s, and 60 s trace groups and in one out of two 120 s trace groups, but not in the control groups. In the 20 and 60 s trace procedures, the fish crowded together in the small feeding area during the trace interval, showing strong anticipatory behaviour. In all the conditioned groups, the fish responded to the CS within eight trials, demonstrating rapid learning. At 88 and 70 days after the end of the conditioning experiments, the delay and 20 s trace groups, respectively, were presented the CS six times at 2-h intervals without reward. All groups responded to the light signal, demonstrating memory retention after at least 3 months. This study demonstrates that Atlantic cod has an impressively good ability to associate two time-separated events and long time retention of learnt associations.     

How to quantify support for and against the null hypothesis: A flexible WinBUGS implementation of a default Bayesian t test

We propose a sampling-based Bayesian t test that allows researchers to quantify the statistical evidence in favor of the null hypothesis. This Savage—Dickey (SD) t test is inspired by the Jeffreys—Zellner—Siow (JZS) t test recently proposed by Rouder, Speckman, Sun, Morey, and Iverson (2009). The SD test retains the key concepts of the JZS test but is applicable to a wider range of statistical problems. The SD test allows researchers to test order restrictions and applies to two-sample situations in which the different groups do not share the same variance.     

In search of the nonconscious sources of goal pursuit: Accessibility and positive affective valence of the goal state

Two experiments tested the hypothesis that the mere priming of the representation of a goal state motivates people to pursue this state to the extent that it is associated with positive affect. In Experiment 1, all participants completed an affective priming task in which the goal concept of “socializing” was primed and tested for positive valence. Subsequently, they were given an instrumental task which provided the opportunity to pursue that state. It was established that participants put more effort in the task to attain the primed goal state when the implicitly assessed affective valence of the state was more positive. Experiment 2 replicated and extended these effects by showing that a stronger association of the goal state with positive affect—as assessed by the EAST—led to more effort to attain the state, but only when “socializing” was primed.     

Neural coding of reward magnitude in the orbitofrontal cortex of the rat during a five-odor olfactory discrimination task

The orbitofrontal cortex (OBFc) has been suggested to code the motivational value of environmental stimuli and to use this information for the flexible guidance of goal-directed behavior. To examine whether information regarding reward prediction is quantitatively represented in the rat OBFc, neural activity was recorded during an olfactory discrimination “go”/“no-go” task in which five different odor stimuli were predictive for various amounts of reward or an aversive reinforcer. Neural correlates related to both actual and expected reward magnitude were observed. Responses related to reward expectation occurred during the execution of the behavioral response toward the reward site and within a waiting period prior to reinforcement delivery. About one-half of these neurons demonstrated differential firing toward the different reward sizes. These data provide new and strong evidence that reward expectancy, regardless of reward magnitude, is coded by neurons of the rat OBFc, and are indicative for representation of quantitative information concerning expected reward. Moreover, neural correlates of reward expectancy appear to be distributed across both motor and nonmotor phases of the task.
