Memory illusions in children of three age groups (5-9 8-, and 11-year-olds) were investigated using a modified version of the Deese-Roediger-McDermott (DRM) procedure. Children from each age group ...falsely recalled nonpresented items related to the study lists. However, the nature of the intrusions varied across the different groups. The 5-year-olds were more likely to falsely recall words that rhymed with the studied items than to recall unrelated items, whereas the 11-year-olds were more likely to falsely recall words that were semantically related to the list theme than to produce either rhyming or unrelated intrusions. Intrusions made by the 8- year-olds were equally likely to be semantic, rhyming, or unrelated to study items. The results are consistent with the notion of a developmental shift from phonological to semantic associations, leading to qualitatively different memory distortions in children of different ages.
Two experiments investigated whether mental toughness (MT) is associated with the ability to respond to and/or overcome unwanted information during real-time sport performance. Participants were male ...snooker players ranging from club to professional level, and MT was measured using the MTQ48 (Clough et al., 2002). In experiment 1, players performed five break-off shots and received deceptive feedback (either positive or negative) from the researcher about their performance relative to other players. Then they performed another five break-offs. Results showed a significant decline in performance following feedback, but no interaction with the nature of feedback or MT variables. In experiment 2, feedback was delivered by a coach and yielded a significant effect on performance. Specifically, negative feedback improved performance while positive feedback impaired performance. The Life Control subscale of the MTQ48 was a significant covariate. The results suggest that negative feedback, delivered constructively by a respected figure, may act as a catalyst for performance enhancement in snooker and that this is moderated by MT.
•Negative feedback enhances real-time performance accuracy in snooker.•Feedback only effective when delivered by a respected figure (e.g., coach).•Effects of feedback were moderated by mental toughness.

Ezetimibe Added to Statin Therapy after Acute Coronary Syndrome Shows Improvement A study published in the June 18, 2015 edition of New England Journal of Medicine suggests that the addition of ezetimibe to statin therapy after acute coronary syndrome resulted in incremental lowering of LDL cholesterol levels and improved cardiovascular outcomes.
Two experiments investigated the role of visual imagery in prospective memory (PM). In experiment 1, 140 participants completed a general knowledge quiz which included a PM task of writing a letter ..."X" next to any questions that referred to space. Participants either visualised themselves performing this task, verbalised an implementation intention about the task, did both, or did neither. Performance on the PM task was enhanced in both conditions involving visual imagery but not by implementation intentions alone. In experiment 2, 120 participants imagined themselves writing a letter "X" next to questions about space, or in a bizarre imagery condition imagined themselves drawing an alien next to those questions. Relative to the control condition, PM was significantly enhanced when participants imagined writing a letter "X" next to the target questions, but not by the bizarre imagery task. The findings indicate that the robust effects of imagery observed in retrospective memory also extend to PM.
The relationship between buyers and suppliers is the cornerstone of all supply networks. This exploratory investigation seeks to examine whether an existing approach developed for, and used ...extensively in the manufacturing quality milieu, could be adapted to the dyadic relationships found at the supply network interface between food multiple retailers and their suppliers. This investigation evaluates the concept of the use of control charts to examine supplier's delivery performance into the retailer's distribution centres and to relate this to on-shelf-availability in the retailer's stores. It was found that these control charts could be adapted to monitor the supplier/retailer interface and that the results could potentially be used to monitor and manage the buyer/supplier relationship effectively.
Three experiments investigated the relationship between future thinking and false memories. In Experiment 1, participants remembered familiar events (e.g., a holiday) from their past, imagined ...planning the same events in the future, or took part in a control condition in which they visualized typical events. They then rated a series of schema-related and schema-unrelated nouns for how likely they were to be encountered within those events. In a surprise recognition test, participants in the future condition falsely recognized more schema-related items than participants in the past and control conditions. No reliable effects of rating condition were observed in correct recognition. Experiment 2 found the same pattern when participants imagined unfamiliar events (e.g., taking part in a bank robbery) from past or future perspectives. Participants in Experiment 3 remembered a past or imagined a future holiday and were then instructed to generate items that someone might take on a holiday. Participants in the future condition generated more nonstudied items and fewer studied items relative to participants in the past condition. The findings of Experiments 1 and 2 indicate that simulating future events enhances the activation of related items that gives rise to false memories. The findings of Experiment 3 suggest that these activation processes play an adaptive role in guiding the planning of future events.
Eight experiments investigated the effects of visual, spatial, auditory, and executive interference on the symbolic comparison of animal size and ferocity, semantic goodness of words, and numbers. ...Dynamic visual noise (DVN) and the reading of visually presented stimulus items were shown to selectively interfere with response times on the animal size comparison task, though the slope of the symbolic distance function remained unchanged. Increased change of DVN significantly increased interference, but interference was reduced by equiluminant DVN. Spatial tracking reduced the slope of the symbolic distance function in contrast to an executive task that only increased mean latency and errors for all comparisons. Results suggest that the generation of an image is necessary for size comparison, but neither imagery nor executive function is responsible for the frequently observed distance-time function.
Two experiments used the distinction between remembering and knowing to investigate the effects of exact and category repetition in recognition memory. In Experiment 1, exact repetition enhanced ...remember responses but had no reliable effect on know responses. In Experiment 2, category repetition enhanced correct know responses but had no effect on correct remember responses. Category repetition also increased false positive remember and know responses. It is argued that exact repetition influences the recollection component of recognition memory via the creation of multiple episodic traces, each of which is potentially capable of supporting a remember response, whereas category repetition influences the familiarity component of recognition memory by enhancing the fluency with which test items are processed.
False memories created by the Deese/Roediger-McDermott (DRM) paradigm are often accompanied by contextual information. Yet, research investigating the effects of context on false memories is ...surprisingly scarce. We used the context-dependent memory (CDM) model to construct same versus different context conditions using odours as contexts and DRM lists as to-be-remembered stimuli. Experiment 1 showed that levels of correct recall were higher in the same-context condition than in the changed-context condition, but no effects of context were observed in false recall. Experiment 2 used different odours and a longer retention interval and showed that context-dependent memory effects were found for both true and false memory. For true memory, context reinstatement improved memory, whilst simultaneously reducing false memory. Theoretical and forensic implications of these findings are discussed.

IPv4 network addresses are running out and the deployment of IPv6 networking in many places is now well underway. Following the work of the HEPiX IPv6 Working Group, a growing number of sites in the ...Worldwide Large Hadron Collider Computing Grid (WLCG) are deploying dual-stack IPv6/IPv4 services. The aim of this is to support the use of IPv6-only clients, i.e. worker nodes, virtual machines or containers. The IPv6 networking protocols while they do contain features aimed at improving security also bring new challenges for operational IT security. The lack of maturity of IPv6 implementations together with the increased complexity of some of the protocol standards raise many new issues for operational security teams. The HEPiX IPv6 Working Group is producing guidance on best practices in this area. This paper considers some of the security concerns for WLCG in an IPv6 world and presents the HEPiX IPv6 working group guidance for the system administrators who manage IT services on the WLCG distributed infrastructure, for their related site security and networking teams and for developers and software engineers working on WLCG applications.
