Infusion of protein synthesis inhibitors in the entorhinal cortex blocks consolidation but not reconsolidation of object recognition memory

Memory consolidation and reconsolidation require the induction of protein synthesis in some areas of the brain. Here, we show that infusion of the protein synthesis inhibitors anisomycin, emetine and cycloheximide in the entorhinal cortex immediately but not 180 min or 360 min after training in an object recognition learning task hinders long-term memory retention without affecting short-term memory or behavioral performance. Inhibition of protein synthesis in the entorhinal cortex after memory reactivation involving either a combination of familiar and novel objects or two familiar objects does not affect retention. Our data suggest that protein synthesis in the entorhinal cortex is necessary early after training for consolidation of object recognition memory. However, inhibition of protein synthesis in this cortical region after memory retrieval does not seem to affect the stability of the recognition trace.     

Working memory training revisited: A multi-level meta-analysis of n-back training studies

The efficacy of working memory (WM) training has been a controversial and hotly debated issue during the past years. Despite a large number of training studies and several meta-analyses, the matter has not yet been solved. We conducted a multi-level meta-analysis on the cognitive transfer effects in healthy adults who have been administered WM updating training with n-back tasks, the most common experimental WM training paradigm. Thanks to this methodological approach that has not been employed in previous meta-analyses in this field, we were able to include effect sizes from all relevant tasks used in the original studies. Altogether 203 effect sizes were derived from 33 published, randomized, controlled trials. In contrast to earlier meta-analyses, we separated task-specific transfer (here untrained n-back tasks) from other WM transfer tasks. Two additional cognitive domains of transfer that we analyzed consisted of fluid intelligence (Gf) and cognitive control tasks. A medium-sized transfer effect was observed to untrained n-back tasks. For other WM tasks, Gf, and cognitive control, the effect sizes were of similar size and very small. Moderator analyses showed no effects of age, training dose, training type (single vs. dual), or WM and Gf transfer task contents (verbal vs. visuospatial). We conclude that a substantial part of transfer following WM training with the n-back task is task-specific and discuss the implications of the results to WM training research.

Exploring the factors affecting child and adolescent psychotherapists' and counsellors' decision‐making in clinical work with parents

This study examined interventions with parents/carers in child and adolescent counselling and psychotherapy (CAP). The aim was to investigate clinicians' rationale behind their decision to work with parents and what types of interventions they use. Furthermore, the nature of clinicians' core training with regard to interventions with parents was investigated. The study used both quantitative data and qualitative textual data from an online survey of 110 CAP clinicians. There was significant agreement, regardless of previous training or level of experience, that clinical work with parents in CAP is beneficial, but little consensus for a rationale or model for best practice. There was a relationship between training, theoretical orientation and whether CAPs felt competent to work with parents. Unexpectedly, a significant number (83%) of integrative practitioners said that there had been ‘little’ to ‘none at all’ focus on working with parents on their core training course. Other unforeseen findings were in the domain of working outside generally accepted boundaries for CAP, with a notable number of clinicians making home visits—24.1% with parents alone and 38.9% with parent and child together—along with 47.2% using phone calls and/or email for coaching and support with parents. Many clinicians were candid about their sense of a lack of competence in working with parents, even though at least half were senior, experienced clinicians. A number of these practitioners made specific reference to the wish for further specialist training, with many asking for signposting to where further training could be obtained.     

The adaptation of an adult group screening test for dyslexia into Finland-Swedish: normative data for university students and the effects of language background on test performance

We present a Finland-Swedish adaptation of the Sweden-Swedish group screening test for dyslexia for adults and young adults DUVAN (Lundberg & Wolff, 2003) together with normative data from 143 Finland-Swedish university students. The test is based on the widely held phonological deficit hypothesis of dyslexia and consists of a self-report and five subtests tapping phonological working memory, phonological representation, phonological awareness, and orthographic skill. We describe the test adaptation procedure and show that the internal reliability of the new test version is comparable to the original one. Our results indicate that the language background (Swedish, Finnish, early simultaneous Swedish-Finnish bilingualism) should be taken into account when interpreting the results on the Finland-Swedish DUVAN test. We show that the FS-DUVAN differentiates a group of students with dyslexia diagnosis from normals, and that a low performance on the FS-DUVAN correlates with a positive self-report on familial dyslexia and with a history of special education in school. Finally, we analyze the sensitivity and specificity of the FS-DUVAN for dyslexia among university students.     

Remembering intentions: testing a new method of investigation

The paper examines some of the methodological difficulties associated with the investigation of remembering intentions in a laboratory and reports the development of a new and easily administered naturalistic task. The task requires participants to act as a narrator and read aloud a story that they are informed will help the experimenter to obtain necessary test material for another study. Remembering intentions (‘prospective memory’) is examined by presenting a plausible cover story requiring to make a correct substitution for a ‘target’ word which appears on several occasions during the story. This method seems to capture adequately the nature of prospective remembering and preclude the occurrence of ceiling, floor and practice effects in performance. By distinguishing late responses from on-time or successful prospective memory responses it also stresses the importance of taking into account the speed with which one recovers from his or her prospective memory failures. Finally, this task enables us to collect reliable and consistent quantitative measures of remembering intentions and to investigate a variety of methodologically and theoretically important problems. The results of Experiments 1a and 1b (Study 1) suggest that both the type of prospective memory task (main versus extra) and subjects' awareness of the phenomenon under investigation are important influences on performance. On the other hand, no effects of (1) a short 5-minute delay between prospective memory instruction and onset of background activity and (2) information about the frequency of target word were revealed (Study 2). The design of a popular experimental paradigm (Einstein and McDaniel, 1990) is examined in the light of these findings. Copyright © 1998 John Wiley & Sons, Ltd.     

Constructions of Participatory Democracy Institutions and Same-Sex Union Rights in Online Public Deliberation in Greece

This article aims to explore the argumentative lines employed in an online public deliberation concerned with legislation on same-sex civil union in Greece. Drawing on rhetorical and discursive developments in political social psychology and sexual citizenship debates, the article focuses on arguments regarding the relevance and the implications of public deliberation on the construction of LGBTQI+ claims and rights. The analytic corpus consisted of 1,000 comments, analyzed with the concepts and tools of Rhetorical and Critical Discursive Social Psychology. A recurring line of arguing against the legislation questioned the democratic quality of public deliberation, representing it as a means used to legitimize predetermined decisions. Moreover, overtly discriminatory arguments were predicated on the values of participatory democracy. Accounts in favor of the legislation, though, challenged public deliberation on the grounds that it allows room for the dispute of universal human rights. The potential contribution of these findings to the understanding of the dilemmas of participatory democracy, the reproduction of heteronormativity, and the assimilation of LGBTQI+ claims is discussed.     

Recognition of Inflected Words in a Morphologically Limited Language: Frequency Effects in Monolinguals and Bilinguals

The effect of word frequency on the processing of monomorphemic vs. inflected words was investigated in a morphologically relatively limited language, Swedish, with two participant groups: early Finnish–Swedish bilinguals and Swedish monolinguals. The visual lexical decision results of the monolinguals suggest morphological decomposition with low-frequency inflected nouns, while with medium- and high-frequency inflections, full-form processing was apparently employed. The bilinguals demonstrated a similar pattern. The results suggest that morpheme-based recognition is employed even in a morphologically limited language when the inflectional forms occur rarely. With more frequent inflectional forms, full-form representations have developed for both mono- and bilingual speakers. In a comparable study employing a morphologically rich language, Finnish, Lehtonen and Laine (2003, Bilingualism: Language and Cognition, 6, 213–225) observed full-form access only at the high-frequency range and only for monolinguals. These differences suggest that besides word frequency and language background, the morphological richness of a language affects the processing mode employed with polymorphemic wordsThis study was financially supported by a grant (#20010) from the Joint Committee of the Nordic Social Science Research Councils (NOS-S).
