In meta-analysis, the usual way of assessing whether a set of single studies is homogeneous is by means of the Q test. However, the Q test only informs meta-analysts about the presence versus the absence of heterogeneity, but it does not report on the extent of such heterogeneity. Recently, the I 2 index has been proposed to quantify the degree of heterogeneity in a meta-analysis. In this article, the performances of the Q test and the confidence interval around the I 2 index are compared by means of a Monte Carlo simulation. The results show the utility of the I 2 index as a complement to the Q test, although it has the same problems of power with a small number of studies.

Though moral intuitions and choices seem fundamental to our core being, there is surprising new evidence that people resolve moral dilemmas differently when they consider them in a foreign language (Cipolletti et al., 2016; Costa et al., 2014a; Geipel et al., 2015): People are more willing to sacrifice 1 person to save 5 when they use a foreign language compared with when they use their native tongue. Our findings show that the phenomenon is robust across various contexts and that multiple factors affect it, such as the severity of the negative consequences associated with saving the larger group. This has also allowed us to better describe the phenomenon and investigate potential explanations. Together, our results suggest that the foreign language effect is most likely attributable to an increase in psychological distance and a reduction in emotional response. (PsycINFO Database Record

The authors present a model to account for the miscombination of features when stimuli are presented using the rapid serial visual presentation (RSVP) technique (illusory conjunctions in the time domain). It explains the distributions of responses through a mixture of trial outcomes. In some trials, attention is successfully focused on the target, whereas in others, the responses are based on partial information. Two experiments are presented that manipulated the mean processing time of the target-defining dimension and of the to-be-reported dimension, respectively. As predicted, the average origin of the responses is delayed when lengthening the target-defining dimension, whereas it is earlier when lengthening the to-be-reported dimension; in the first case the number of correct responses is dramatically reduced, whereas in the second it does not change. The results, a review of other research, and simulations carried out with a formal version of the model are all in close accordance with the predictions.

A meta-analysis was conducted to reach a pooled estimate of the diagnostic accuracy of the SCOFF. The 15 selected studies represented a total of 882 cases and 4350 controls. The main criterion for inclusion was that the primary study had provided diagnostic classification with both a diagnostic reference and with the SCOFF (with five items and a cut-off point of two). The pooled estimates were .80 (sensitivity) and .93 (specificity). The moderator variables gender and type of measure for the diagnostic reference (interview versus psychometric tests) account for part of the observed variability. For diagnostic references based on interviews the estimate of the efficacy improves significantly. For the studies that match this criterion the sensitivity is .882 and the specificity .925 (diagnostic odds ratio, 92.19). The main conclusion was that the five questions of the SCOFF constitute a very useful screening tool, in several languages; it is highly recommended for screening purposes.

The aim of this study was to examine and identify the psychological, clinical and sociodemographic factors associated with emotional well-being by type of caregiver. A cross-sectional study was conducted among 185 primary caregivers and 92 secondary caregivers of patients with an eating disorder using the Hospital Anxiety and Depression Scale, the Experience of Caregiving Inventory and the Eating Disorders Symptom Impact Scale. According to a multiple regression analysis, a total of four models were obtained accounting for 42%-47% of the variance in emotional well-being. The variable that accounted for most of the variance of emotional well-being in three of the models was the impact of nutrition. Improving aspects of the relationships with the patients reduced anxiety and depression levels in primary caregivers. Similarly, a positive personal experience reduced depression in secondary caregivers. A higher education level was associated with decreased anxiety levels in both types of caregivers. Specific family interventions including both types of caregivers may be useful for providing emotional and adaptive personal coping skills.

These results highlight how daily social interactions can influence unhealthy eating practices in adolescent girls and boys, and suggest that weight-related issues of parents and peers can be transmitted to adolescents.

In two experiments, we examined the effects of task and location switching on the accuracy of reporting target characters in an attentional blink (AB) paradigm. Single-character streams were presented at a rate of 100 msec per character in Experiment 1, and successive pairs of characters on either side of fixation were presented in Experiment 2. On each trial, two targets appeared that were either white letters or black digits embedded in a stream of black letter distractors, and they were separated by between zero and five items in the stream (lags 1-6). Experiment 1 showed that report of the first target was least accurate if it immediately preceded the second target and if the two targets were either both letters or both digits (task repetition cost). Report of the second target was least accurate if one or two distractors intervened between the two targets (the U-shaped AB lag effect) and if one target was a letter and the other a digit (task switch cost). Experiment 2 added location uncertainty as a factor and showed similar effects as Experiment 1, with one exception. Lag 1 sparing (the preserved accuracy in reporting the second of two targets if the second immediately follows the first) was completely eliminated when the task required attention switching across locations. Two-way additive effects were found between task switching and location switching in the AB paradigm. These results suggests separate loci for their attentional effects. It is likely that the AB deficit is due mainly to central memory limitations, whereas location-switching costs occur at early visual levels. Task-switching costs occur at an intermediate visual level, since the present task switch involved encoding differences without changes in stimulus-response mapping rules (i.e., the task was character identification for both letters and digits).
