Should Authors be Requested to Suggest Peer Reviewers?

As part of a continuous process to explore the factors that might weaken or corrupt traditional peer review, in this paper, we query the ethics, fairness and validity of the request, by editors, of authors to suggest peer reviewers during the submission process. One of the reasons for the current crisis in science pertains to a loss in trust as a result of a flawed peer review which is by nature biased unless it is open peer review. As we indicate, the fact that some editors and journals rely on authors’ suggestions in terms of who should peer review their paper already instills a potential way to abuse the trust of the submission and publishing system. An author-suggested peer reviewer choice might also tempt authors to seek reviewers who might be more receptive or sympathetic to the authors’ message or results, and thus favor the outcome of that paper. Authors should thus not be placed in such a potentially ethically compromising situation, especially as a mandatory condition for submission. However, the fact that they do not have an opt-out choice during the submission process—especially when using an online submission system that makes such a suggestion compulsory—may constitute a violation of authors’ rights.     

Ethical Design in the Internet of Things

Even though public awareness about privacy risks in the Internet is increasing, in the evolution of the Internet to the Internet of Things (IoT) these risks are likely to become more relevant due to the large amount of data collected and processed by the “Things”. The business drivers for exploring ways to monetize such data are one of the challenges identified in this paper for the protection of Privacy in the IoT. Beyond the protection of privacy, this paper highlights the need for new approaches, which grant a more active role to the users of the IoT and which address other potential issues such as the Digital Divide or safety risks. A key facet in ethical design is the transparency of the technology and services in how that technology handles data, as well as providing choice for the user. This paper presents a new approach for users’ interaction with the IoT, which is based on the concept of Ethical Design implemented through a policy-based framework. In the proposed framework, users are provided with wider controls over personal data or the IoT services by selecting specific sets of policies, which can be tailored according to users’ capabilities and to the contexts where they operate. The potential deployment of the framework in a typical IoT context is described with the identification of the main stakeholders and the processes that should be put in place.     

ROC and z-ROC parameters in word memory: experimental and pre-experimental effects

In this study, ROC and z-ROC parameters are applied in word recognition memory, with words classified according to frequency and class. In doing so, unbiased techniques can be used to assess hits and false alarms and to obtain standardized distributions for each experimental condition. Our results confirm the existence of differences in word recognition memory for experimental exposition time, type of words and other pre-experimental effects. These data are consistent with familiarity and recollection models when words' frequency is used, and with familiarity, recollection and dual-route models when words are organized according to class. Finally, we argue in favour of an interactive processing model (words organized according to frequency) versus a processing model nearer to modularity (words organized according to class).     

Attending to the non-preferred hand improves bimanual coordination in children

The effect of attentional focus in bimanual coordination was investigated from a developmental perspective by examining performance of right- and left-handed children, 5-8-years and 9-12-years old, on bimanual reciprocal tapping tasks. Attentional focus was either specified, by asking the children to attend to the preferred or to the non-preferred hand, or unspecified for the execution of the tasks. When attention was oriented to the non-preferred hand we found a reduced movement time and a lower frequency of errors. Performance differences for handedness and age-groups were observed when the children were oriented to attend to the preferred hand or when there was no instruction regarding attention. These differences in performance were eliminated when attention was oriented to the non-preferred hand.     

Variations in Anxiety and Depression as a Function of ADHD Subtypes Defined by DSM-IV: Do Subtype Differences Exist or Not?

Concerns have been raised about the ability of diagnostic criteria for attention-deficit/hyperactivity disorder (ADHD) to distinguish subtypes that are clearly distinct from each other with regard to clinical correlates. One area of concern is that research regarding differences in anxiety and depression as a function of ADHD subtype has produced discrepant findings. This study was designed to systematically evaluate whether the ADHD subtypes differ with regard to level of internalizing symptoms. From a large pool of children referred to an ADHD center based in a pediatric hospital, children were differentiated into three groups: ADHD, Combined Type (ADHD/COM); ADHD, Inattentive Type (ADHD/I); and a non-ADHD, comparison group (COMP). Parent- and child-report measures using both dimensional and categorical methods were used to assess internalizing symptoms. The results indicated that children with ADHD/COM and ADHD/I had similar levels of anxiety and depression. Subtype differences related to parent-reported depression were accounted for by group differences in level of externalizing problems. The results were discussed with regard to their implications for refining the criteria used to differentiate children with ADHD into subtypes.     

Social closeness of MZ and DZ twin parents towards nieces and nephews

Twins' marriages to non‐twins yield genetically and socially informative kinships. Monozygotic (MZ) twins' genetic identity makes them ‘genetic parents’ of their nieces/nephews, and their nieces/nephews their ‘genetic children’. The present study is the first to apply twin‐family models to study social relatedness. Analyses of twin families (MZ: N = 248; DZ: N = 75) tested evolutionary‐based concepts concerning social closeness, perceived similarity and caretaking. Hypotheses based on Hamilton's inclusive fitness theory were supported: MZ twin aunts/uncles expressed greater social closeness towards their nieces/nephews than DZ twin aunts/uncles; and female twins from same‐sex pairs expressed greater closeness towards their nieces/nephews than male twins from same‐sex pairs. This study underlines benefits of associations between behavioural‐genetic and evolutionary psychological theories, methods and interpretations. Copyright © 2007 John Wiley & Sons, Ltd.     

Interference produces different forgetting rates for implicit and explicit knowledge

Exposure to a repeating set of target strings generated by an artificial grammar in a speeded matching task generates both explicit and implicit knowledge. Previous research has shown that implicit knowledge (assessed via a priming measure) is preserved after a retention interval of one week but explicit knowledge (assessed via recognition) is significantly reduced. In two experiments, we replicated and extended Tunney's findings. Experiment 1 was a partial replication of the experiment conducted by Tunney, and demonstrated that the decline in recognition shown by Tunney was not due to a repetition of test items at the pre and post times of assessment. In addition, Experiment 1 lends credibility to Tunney's assumption that recognition scores assess explicit rather than implicit knowledge. Experiment 2 extended Tunney's findings theoretically by demonstrating that interference can produce the pattern of findings demonstrated in the present Experiment 1 as well as in Tunney.     

Revisiting the Psychometric Properties of the Levenson Self-Report Psychopathy Scale

A number of studies have addressed the dimensionality and the measurement invariance of the Levenson Self-Report Psychopathy scale (LSRP; Levenson, Kiehl, & Fitzpatrick, 1995). However, previous investigations exclusively relied on North American samples and mainly on statistical methods that assume data as normally and continuously distributed. The aim of this study was to further investigate dimensionality and differential item functioning for gender in the 26-item LSRP scale in a Brazilian population-based sample using analytical methods adequate for ordered categorical variables. Findings revealed strong evidence for a 2-factor model, similar to the original factor structure of the instrument. Only 3 items presented negligible differential functioning for gender. We address the implications of these results, and stress the need for expanding research on the measurement and structural invariance of the LSRP scale by means of cross-cultural investigations.
