Children's memory for the duration of a paediatric consultation

To learn about children's ability to estimate the duration of an event many days after it occurred, 6–12‐year‐old children were asked to judge the amount of time (range 5–45 minutes) they spent in the treatment room as part of a paediatric visit. Judgements were made 1 week or 1 month after the visit occurred. Children showed an average error of about 13 minutes. Retention interval did not significantly affect estimates. Other judgements of the length of the interview itself (mean length 8 minutes) provided what may be the first data on children's ability to make immediate retrospective duration estimates. The results also include information about children's capacity to judge how long ago they visited the clinic. Copyright © 2009 John Wiley & Sons, Ltd.     

Imagery encoding and false recognition errors: Examining the role of imagery process and imagery content on source misattributions

Imagery encoding effects on source-monitoring errors were explored using the Deese-Roediger-McDermott paradigm in two experiments. While viewing thematically related lists embedded in mixed picture/word presentations, participants were asked to generate images of objects or words (Experiment 1) or to simply name the items (Experiment 2). An encoding task intended to induce spontaneous images served as a control for the explicit imagery instruction conditions (Experiment 1). On the picture/word source-monitoring tests, participants were much more likely to report "seeing" a picture of an item presented as a word than the converse particularly when images were induced spontaneously. However, this picture misattribution error was reversed after generating images of words (Experiment 1) and was eliminated after simply labelling the items (Experiment 2). Thus source misattributions were sensitive to the processes giving rise to imagery experiences (spontaneous vs deliberate), the kinds of images generated (object vs word images), and the ways in which materials were presented (as pictures vs words).     

A new solution to the problem of luck

The issue of whether and how we have the control necessary for freedom and moral responsibility is central to all control accounts of freedom and moral responsibility. The problem of luck for libertarians aims to show that indeterministic agents are ill-equipped with the control required for freedom and moral responsibility. In view of this, we must either endorse scepticism about the possibility of free and morally responsible agents, or make some form of, possibly revisionary, compatibilism work. In this paper, I shall offer a new solution to the problem of luck for libertarians. After outlining the problem of luck, I shall argue that, given a particular approach to mental causation, indeterminism can be viewed as an essential requirement of free and morally responsible action. After this, I shall distinguish between different types of inability and show how this provides us with a solution to the problem of luck. Finally, I shall consider some advantages and objections to the proposed solution.     

Disconfirmation and dual hypotheses on a more difficult version of wason's 2-4-6 task

This paper reports two experiments in which subjects worked to solve a more difficult version of Wason's 2-4-6 task: instead of the usual “numbers must ascend in order of magnitude” rule, a more general rule, “the three numbers must be different”, was used. The first experiment established that instructing subjects to disconfirm on the “three different numbers” did not significantly improve their performance, as compared with confirmatory and control groups. Disconfirmatory subjects did try to propose more triples at variance with their hypotheses but were unable to obtain the necessary disconfirmatory information.

To help subjects represent the task in a way that facilitated disconfirmation, the second experiment utilized a procedure in which subjects were told that they were looking for two rules, Dax and Med-the Dax rule corresponding to “three different numbers” and the Med rule to its complement, i.e. two or more numbers the same. Of subjects in the Dax-Med condition, 88% solve the rule, as opposed to 21% of subjects in a control condition. Dax-Med subjects tended to search for positive instances of the Med rule, which, in turn, forced them to test the limits of the Dax rule. It was concluded that the Dax-Med manipulation did facilitate a different mental representation of the task than the normal procedure.     

Resource replacement and psychological well-being during unemployment: The role of family support

There is an established inverse relationship between unemployment and psychological wellbeing. However, little is known about the processes that underlie this relationship. Using latent deprivation, conservation of resources, and social capital to form a theoretical framework, this study explored the relationship between the latent benefits associated with employment, family support, and financial strain. In a sample of 174 unemployed individuals, latent benefits were shown to partially mediate the relationship between family support and psychological well-being. Additionally, this mediation was moderated by financial strain, with latent benefits being more related to psychological well-being in those with greater financial strain. These findings provide guidance in understanding how to better address the needs that contribute to psychological well-being in those who are unemployed.
