The effect of sleep-loss on processing information in the functional visual field

Two experiments are reported on the effects of sleepstate on performance in a same/different matching task, where two visual signals are presented under visual angles of either 10°, 45°, or 100°. The first study showed a stronger effect of sleep-loss at a more wide display. The effect consists of two parts: one is interpreted as due to the initiation and execution of the shift of gaze from the one to the other signal, and the other to the requirement of integrating successively perceived signals. These interpretations were tested in the second study. It was found that a more pronounced effect of sleep loss occurred when two signals are successively presented, but not when the signals are simultaneously viewed, while preceded by a shift of gaze. The implications of the data are discussed.     

Detection of a deficit in visual discrimination of pattern following lesions of anterior cortex: role of type of motivation.

6 albino rats were trained under appetitive motivation to perform diametrically opposed visual discriminations of pattern via opposite eyes. Small lesions were subsequently placed unilaterally in anterior neocortex. Following a period of post-surgical recovery, subjects were re-trained on the diammetrically opposed discriminations in alternating 10-trial blocks. Every subject made more post-surgical errors on the discrimination mediated by the eye contralateral to the lesion. Since albino rats have virtually complete decussation of the visual system, this indicates selective impairment in mediation of performance of pattern discrimination in the part of the lesioned hemispheres. Thus, findings previously obtained in studies involving aversive motivation are general to appetitively motivated tasks.     

Utility Monsters for the Fission Age

One of the standard approaches to the metaphysics of personal identity has some counter‐intuitive ethical consequences when combined with maximising consequentialism and a plausible (though not uncontroversial) doctrine about aggregation of consequences. This metaphysical doctrine is the so‐called ‘multiple occupancy’ approach to puzzles about fission and fusion. It gives rise to a new version of the ‘utility monster’ problem, particularly difficult problems about infinite utility, and a new version of a Parfit‐style ‘repugnant conclusion’. While the article focuses on maximising consequentialism for simplicity, the problems demonstrated apply more widely to a range of ethical views, especially flavours of consequentialism. This article demonstrates how these problems arise, and discusses a number of options available in the light of these problems for a consequentialist tempted by a multiple occupancy metaphysics.     

‘Just leave it blank’ non-religious children and their negotiation of prayer in school

ABSTRACT

This article examines how non-religious children experience acts of collective worship and prayer in primary school settings and analyses how they negotiate religion and their non-religious identities in these events. Drawing on ethnographic fieldwork examining non-religious childhoods and collective worship in three English primary schools, the authors explore how non-religious children demonstrate their agency when confronted with particular boundaries and concepts related to religion and non-religion in school contexts. Attending to the experiences, perspectives, and practices of non-religious children adds to our understanding of the varieties of non-religion, which has to date largely focused on elite, adult populations. Focusing on non-religious children’s experiences of prayer reveals how these children did not experience tensions between praying to God and their non-religious identities and articulated their own interpretations of these practices, deepening understanding of the lived realities of non-religious cultures and identities.     

Measuring Possessions as Extensions of Self and Links to Significant Others in Hoarding: the Possessions as Others and Self Inventory

Social value orientations and negotiator outcomes

Social value orientations (SVOs) are known to influence individual behaviour in outcome interdependent settings. By extending these findings to negotiation, this research investigates the relationship between own and partners' SVOs, negotiator strategies and outcomes. Results showed that cooperators, competitors and individualists could be distinguished in terms of initial demands and concessions. Competitors made higher initial demands and larger concessions than individualists or cooperators, suggesting that their ability to maximize outcome differences rests on whether structural features are congruent with this goal. The principal finding of this research was the demonstration that own and partners' SVO interact to determine outcomes. Results showed that the three SVO groups differed in terms of context sensitivity: competitor outcomes were invariant across partners; individualists achieved poor outcomes in negotiations with cooperators and, reciprocally, cooperators attained high outcomes in negotiations with individualists. Additionally, individualist outcomes worsened in their last negotiation, while those of cooperators differed as a function of role and partner's SVO. These results suggest that although the information used by individualists and cooperators differs, for both groups the cognitive representation of negotiations is a further factor influencing their outcomes.     

A review of attachment-based parenting interventions: Recent advances and future considerations

Research evidence has shown that in childhood, a secure attachment to a reliable caregiver is important for future mental health and well-being. The theoretical and research basis for attachment theory continues to grow. As attachment theory has become more widely adopted there are challenges and opportunities both theoretically and in terms of its clinical use. Disordered attachment has been linked to psychopathology including internalising and externalising disorders. However, there are ongoing implications for researchers and clinicians as only the most extreme forms of attachment disorders are included in the current diagnostic systems. A wide range of reliable and validated observational assessments to classify attachment are available. Owing to the growing popularity of attachment-based interventions there is a need to develop assessments which are practical for use in clinical settings. The use of attachment-based parenting interventions in clinical settings is increasing as they have been found to be effective and relevant. This growth presents opportunities to further refine these interventions, so they are easy to deliver in clinical practice and tailored to different populations. Attachment-based interventions are being widely used in Australia, and this has led to a need to understand and adapt the theory, assessments, and interventions to this context. Attachment-based interventions demonstrate the importance of relationships and provide an important tool to support children and families. For psychologists here in Australia there are many opportunities to develop measures and interventions based on attachment theory that fit into the Australia context.     

Is future self-relevance necessary to increase saving for retirement? A replication study

Insufficient saving for retirement is one consequence of excessive discounting of the future but attempts to mitigate it often involve costly or time-intensive personalized interventions. Marques, Mariano, Lima, and Abrams, by contrast, found that using a generic Future Time Perspective questionnaire to increase future “self-relevance” was an effective method to increase money allocation to retirement when the salience of future aging was also higher. Originally conducted in Portugal, the present study aimed to replicate Marques et al’s findings in the UK context. In the present study (n = 219), participants were shown a website advertising a financial product. The results support Marques and colleagues’ assertion that, alone, a website priming future aging was insufficient to increase retirement savings in a money allocation task. However, in contrast to Marques et al’s original findings, we find no evidence that future self-relevance moderates the effect such that priming future aging becomes effective when individuals have higher future self-relevance. Instead, we find that aging primes are ineffective at increasing retirement saving regardless of whether individuals are high or low in future self-relevance. Possible explanations for this discrepancy in findings, including methodological and cultural differences, are explored as well as directions for future research.     

Do infants have a sense of numerosity? A p‐curve analysis of infant numerosity discrimination studies

Research demonstrating that infants discriminate between small (e.g., 1 vs. 3 dots) and large numerosities (e.g., 8 vs. 16 dots) is central to theories concerning the origins of human numerical abilities. To date, there has been no quantitative meta‐analysis of the infant numerical competency data. Here, we quantitatively synthesize the evidential value of the available literature on infant numerosity discrimination using a meta‐analytic tool called p‐curve. In p‐curve the distribution of available p‐values is analyzed to determine whether the published literature examining particular hypotheses contains evidential value. p‐curves demonstrated evidential value for the hypotheses that infants can discriminate between both small and large unimodal and cross‐modal numerosities. However, the analyses also revealed that the published data on infants’ ability to discriminate between large numerosities is less robust and statistically powered than the data on their ability to discriminate small numerosities. We argue there is a need for adequately powered replication studies to enable stronger inferences in order to use infant data to ground theories concerning the ontogenesis of numerical cognition.
