Young infants prefer prosocial to antisocial others

The current study replicates and extends the finding (Hamlin, Wynn & Bloom, 2007) that infants prefer individuals who act prosocially toward unrelated third parties over those who act antisocially. Using different stimuli from those used by Hamlin et al. (2007), somewhat younger subjects, and 2 additional social scenarios, we replicated the findings that (a) infants prefer those who behave prosocially versus antisocially, and (b) these preferences are based on the social nature of the actions. The generality of infants’ responses across multiple examples of prosocial and antisocial actions supports the claim that social evaluation is fundamental to perceiving the world.     

Sorry not today: Self and temporary consumption denial

This research investigates the temporary involuntary loss of symbolically important, meaningful possessions and how consumers manage self identity in this situation. The losses explored occurred within the context of air travel and included where people accustomed to flying in business class had to travel in economy and where high status in a frequent flyer program was lost. Three stages of fieldwork were conducted; participant observation involving 50 international and domestic flights covering 110,000 miles, depth interviews and engagement online with a range of frequent flyer discussion communities. The short‐term, concealable nature of the losses allowed consumers to manipulate private and public meaning to avoid, where possible, the consequences of the loss on self identity. This study contributes by showing that both private and public meanings of lost possessions can be used in identity construction and how identity negotiation can be avoided.

How to Cook Rice: A Review of Ingredients for Teaching anti‐Prejudice

There is a pressing need to address prejudice, racism, and discrimination against marginalised groups in Australia. This involves change from the structural to the individual level. In this article, we discuss the merits of individual anti‐prejudice mechanisms within the Australian context. First, we expand on nine mechanisms described in a previous paper and then review five new mechanisms. We conclude that while some mechanisms are likely to be useful regardless of location, others need to be tailored to the local context. We also conclude that effective interventions need to utilise multiple mechanisms. It is hoped that the synthesis of the different mechanisms provided here will assist anti‐prejudice researchers, practitioners, and policymakers striving to improve relations among different groups in our society.     

Visual search and foraging compared in a large-scale search task

It has been argued that visual search is a valid model for human foraging. However, the two tasks differ greatly in terms of the coding of space and the effort required to search. Here we describe a direct comparison between visually guided searches (as studied in visual search tasks) and foraging that is not based upon a visually distinct target, within the same context. The experiment was conducted in a novel apparatus, where search locations were indicated by an array of lights embedded in the floor. In visually guided conditions participants searched for a target defined by the presence of a feature (red target amongst green distractors) or the absence of a feature (green target amongst red and green distractors). Despite the expanded search scale and the different response requirements, these conditions followed the pattern found in conventional visual search paradigms: feature-present search latencies were not linearly related to display size, whereas feature-absent searches were longer as the number of distractors increased. In a non-visually guided foraging condition, participants searched for a target that was only visible once the switch was activated. This resulted in far longer latencies that rose markedly with display size. Compared to eye-movements in previous visual search studies, there were few revisit errors to previously inspected locations in this condition. This demonstrates the important distinction between visually guided and non-visually guided foraging processes, and shows that the visual search paradigm is an equivocal model for general search in any context. We suggest a comprehensive model of human spatial search behaviour needs to include search at a small and large scale as well as visually guided and non-visually guided search.     

Reorientation in the real world: the development of landmark use and integration in a natural environment

An influential series of studies have argued that young children are unable to use landmark information to reorient. However, these studies have used artificial experimental environments that may lead to an underestimation of the children’s ability. We tested whether young children could reorient using landmarks in an ecologically valid setting. Children aged between 3 and 7 years completed a reorientation task in open parkland, and the properties of the search array (size and distinctiveness) were manipulated in a within-subjects design. Responses were recorded using Global Positioning Systems technology. All age groups performed above chance level, demonstrating that young children can reorient using natural landmarks. This behaviour was modulated by the nature of the search array: children were more accurate when the locations were spaced in a large array, and when the search locations were distinctively coloured. This suggests that the integration between landmarks and search locations, at different spatial scales, is a key factor in characterising human reorientation in the real world.     

Moral and Nonmoral Freedom in Kant

Many scholars, in view of the close link that he draws between morality and freedom, argue that Kant does not think that there are free choices between nonmoral ends. On this view, Kant only posits a freedom to resist our desires and act morally. We are still responsible for immoral choices because we always have the power to act morally. Henry Allison has opposed this reading by arguing that Kant grounds a notion of nonmoral freedom in the Incorporation Thesis. In this paper, I criticize Allison's argument and then try to replace it with an alternative that grounds nonmoral freedom in morality.     

Judgment of angle size: An experimental appraisal

Previous work on the estimation of angle size suggested that three factors play a significant part in the forming of an accurate estimation: the size of the angle, its orientation, and the mode in which the response is made. An examination of the judgment by 60 Ss of 12 angles under varied conditions of orientation, response mode, and cue was carried out with the result that the importance of size and orientation was confirmed. Despite an overall significant difference in estimation between response modes, there was no indication of a consistent effect across angles for the different modes. Predictions on the influence of orientation made by Fisher and Beery were tested, and while the former investigator was adequately supported, the latter was held to have reported results on a limited sample of angles which do not generalize to the wider range of angles used in the present study.     

Flexible target representations underlie repetition priming in visual search

Repeating target features across consecutive visual search trials can influence response time. Three experiments are reported that show that this repetition priming is dependent on the exact stimulus configuration and feature type. In Experiment 1 the target was defined relative to distractors by its orientation and target colour was task irrelevant. The roles played by these features were reversed in Experiment 2. Repeating target colour across trials speeded responses in both Experiments 1 and 2. Repeating orientation significantly slowed responses in Experiment 1 but had no significant effect in Experiment 2. Existing feature-based and episodic memory-based explanations of priming cannot account for these data, but instead more flexible explanations are required. Experiment 3 showed that significant positive priming results from repeating distractor-defining orientation, indicating that priming of pop-out effects previously reported in the literature may result from combined target and distractor effects.
