The Role of External Sources of Information in Children's Evaluative Food Categories

Evaluative food categories are value‐laden assessments, which reflect the healthfulness and palatability of foods (e.g. healthy/unhealthy, yummy/yucky). In a series of three studies, this research examines how 3‐ to 4‐year‐old children (N = 147) form evaluative food categories based on input from external sources of information. The results indicate that children prefer to ask a mom and teacher over a cartoon and child for information about the evaluative status of foods. However, children are cautious to accept information about healthy foods from all of the external sources compared with unhealthy, yummy and yucky foods. The results also indicate that providing information about the positive taste of healthy foods helps to encourage children to select healthy foods to eat. Taken together, these results have potential implications for children's health and nutrition education. Copyright © 2011 John Wiley & Sons, Ltd.     

Thinking ethically about the global in ‘Global Ethics’

In what follows, I claim that the ‘global’ in ‘Global Ethics’ needs also to be thought about in a different way, not as the scope or object of ethical judgement but in relation to the worlds reproduced by the practice of ethical judgement itself. In summary, ethical reflection on the meaning of the ‘global’ in the practice of Global Ethics as a field of academic inquiry is what is required if the future of Global Ethics is to be something other than Ethics or Applied Ethics as traditionally conducted.     

Situational moral adjustment and the happy victimizer

In this study we examine the possibility that the happy victimizer phenomenon (HVP), which is generally thought to be restricted to a specific period in middle childhood, also appears among adults. In contrast to other studies that explain the HVP as a lack of moral motivation or an insufficiently developed moral self, we propose to explain HVP in terms of a specific moral stage, i.e., a specific kind of moral reasoning. In particular we identify HV-typical moral reasoning with a sub-form of Kohlberg Stage 2. Adult usage of this moral stage is then explained in terms of situation-specificity. We also try to elaborate the idea of situational adjustment and to reveal the processes of activation and usage of previously acquired moral stage principles. Our empirical study shows that adults use HV-typical principles in specific situations.     

Extinction in human learning and memory

In two experiments, participants were given extinction training in a human causal learning task. In both experiments, three critical experimental cues were paired with different outcomes in a first phase of training and were then extinguished in a second phase. Three control cues were given the same treatment in the first phase of training, but were not then presented in the second phase. Participants' ability to correctly identify the outcome with which each cue had been paired in the first phase was lower for extinguished than for control cues. Causal attributions to the extinguished cues were also lower than those to the control cues, a difference that correlated with outcome memory. These data are consistent with the idea that extinction in causal judgement is due, at least in part, to a failure to remember the cue–outcome relationship encoded in the first phase of training.     

Retrieval dynamics in self-terminated memory search

Attended stimuli are perceived as occurring earlier than unattended stimuli. This phenomenon of prior entry is usually identified by a shift in the point of subjective simultaneity (PSS) in temporal order judgements (TOJs). According to its traditional psychophysical interpretation, the PSS coincides with the perception of simultaneity. This assumption is, however, questionable. Technically, the PSS represents the temporal interval between two stimuli at which the two alternative TOJs are equally likely. Thus it also seems possible that observers perceive not simultaneity, but uncertainty of temporal order. This possibility is supported by prior-entry studies, which find that perception of simultaneity is not very likely at the PSS. The present study tested the percept at the PSS in prior entry, using peripheral cues to orient attention. We found that manipulating attention caused varying temporal perceptions around the PSS. On some occasions observers perceived the two stimuli as simultaneous, but on others they were simply uncertain about the order in which they had been presented. This finding contradicts the implicit assumption of most models of temporal order perception, that perception of simultaneity inevitably results if temporal order cannot be discriminated.     

Moral emotions and the envisaging of mitigating circumstances for wrongdoing

Anger may be more responsive than disgust to mitigating circumstances in judgements of wrongdoing. We tested this hypothesis in two studies where we had participants envision circumstances that could serve to mitigate an otherwise wrongful act. In Study 1, participants provided moral judgements, and ratings of anger and disgust, to a number of transgressions involving either harm or bodily purity. They were then asked to imagine and report whether there might be any circumstances that would make it all right to perform the act. Across transgression type, and controlling for covariance between anger and disgust, levels of anger were found to negatively predict the envisioning of mitigating circumstances for wrongdoing, while disgust was unrelated. Study 2 replicated and extended these findings to less serious transgressions, using a continuous measure of mitigating circumstances, and demonstrated the impact of anger independent of deontological commitments. These findings highlight the differential relationship that anger and disgust have with the ability to envision mitigating factors.     

Cognitive load on working memory both encourages and discourages reasoning bias regarding the mental states of others

Theory of mind (ToM) refers to the ability to reason about the mental states of others. An increasing number of studies have revealed that working memory (WM) plays an important role in ToM. The present study applied WM loads to adults during a ToM task in order to investigate the impact on mental‐state reasoning performance. The task required participants to estimate the probabilities of several possible behaviours for a protagonist following the presentation of a ToM story. Participants were also required to maintain a meaningless two‐ (light WM load) or seven‐letter English alphabet string (heavy WM load) during story comprehension and mental‐state reasoning. The results show that the combination of light WM load applied during story comprehension with heavy WM load during mental‐state reasoning results in an overestimation of the probability that the protagonist's behaviour will accord with a participant's knowledge. Conversely, a heavy WM load applied during story comprehension, regardless of the type of WM load during mental‐state reasoning, did not result in this probability estimation bias. We discuss these findings from the perspective of a WM representation account.     

Alexithymia increases moral acceptability of accidental harms

Previous research shows that when people judge moral acceptability of others' harmful behaviour, they not only take into account information about the consequences of the act but also an actor's belief while carrying out the act. A two-process model has been proposed to account for this pattern of moral judgements and posits: (1) a causal process that detects the presence of a harmful outcome and is motivated by empathic aversion stemming from victim suffering; (2) a mental state-based process that attributes beliefs, desires, intentions, etc. to the agent in question and is motivated by imagining personally carrying out harmful actions. One prediction of this model would be that personality traits associated with empathy deficits would find accidental harms more acceptable not because they focus on innocent intentions but because they have reduced concern for the victim's well-being. In this study, we show that one such personality trait, viz. alexithymia, indeed exhibits the predicted pattern and this increased acceptability of accidental harm in alexithymia is mediated by reduced dispositional empathic concern. Results attest to the validity of two-process model of intent-based moral judgements and emphasise key role affective empathy plays in harm-based moral judgements.     

Causal judgements about two causal candidates: Accounting for occurrences,estimating strength,and the importance of interaction judgements

When two possible causes of an outcome are under consideration, contingency information concerns each possible combination of presence and absence of the two causes with occurrences and nonoccurrences of the outcome. White (2008) proposed that such judgements could be predicted by a weighted averaging model integrating these kinds of contingency information. The weights in the model are derived from the hypothesis that causal judgements seek to meet two main aims, accounting for occurrences of the outcome and estimating the strengths of the causes. Here it is shown that the model can explain many but not all relevant published findings. The remainder can be explained by reasoning about interactions between the two causes, by scenario-specific effects, and by variations in cell weight depending on quantity of available information. An experiment is reported that supports this argument. The review and experimental results support the case for a cognitive model of causal judgement in which different kinds of contingency information are utilised to satisfy particular aims of the judgement process.
