Age‐related changes in the control of episodic retrieval: an ERP study of recognition memory in children and adults

We examined developmental aspects of the ability to monitor the temporal context of an item’s previous occurrence while event‐related potentials (ERPs) were recorded. In a continuous recognition task, children between 10 and 12 years and young adults watched a stream of pictures repeated with a lag of 10–15 intervening items and indicated recurrences. In a second run, these already familiar pictures were repeated as non‐targets along with new pictures, while subjects were instructed to indicate only recurrences within the run. Young adults were able to maintain high performance levels in both tasks, whereas children had longer response times and committed a large number of false alarms to non‐targets. ERPs in both age groups showed similar parietal old/new effects for target repetitions within runs. In addition, adults’ ERPs showed similar old/new effects at frontal electrodes for repetitions and non‐targets, presumably reflecting assessments of familiarity, whereas for children repeated relative to first presentations were associated with more negative‐going waveforms at anterior frontal recording sites. Together, these results suggest a continuing maturation of the brain networks assessing novelty or familiarity. Recollection as indexed by parietal old/new effects appeared similar between young adults and children, but the development of controlled episodic retrieval, resulting in recollection of non‐target information, appears to continue well into adolescence.     

Zur Differenzierung zwischen unsicheren und aggressiven Teilnehmern beim Gruppentraining Sozialer Kompetenzen (GSK) im Straf- und Maßregelvollzug

The cognitive-behavioural group training for social competence “GSK” [16] has proven to also be effective in the penal system [28]. The present study examines if a targeted differentiating assessment prior to the intervention and a thereon based homogeneous group composition with regard to insecure and aggressive behaviour patterns can enhance the effectiveness of the “GSK” in the penal system and in a forensic hospital unit. Altogether 48 male delinquents across both settings were therefore divided into a “homogeneous insecure” group, a “homogeneous aggressive” group and a “heterogeneous” group. Pre-post-comparisons show that the intervention is effective for all three groups and also in both settings, the penal system and the forensic hospital unit. The “homogeneous aggressive” group revealed the strongest intervention effects.     

Horizontal and vertical Simon effect: different underlying mechanisms?

Reaction times are usually faster when stimulus and response occur at the same location than when they do not, even if stimulus location is irrelevant to the task (Simon effect). This effect was found with both horizontal and vertical stimulus-response arrangements. The same mechanisms have been proposed to be involved in either case. Here, we compared a horizontal and a vertical Simon task by means of a RT time-course analysis of the Simon effect. Also, we analysed the lateralised readiness potential (LRP), an index of covert response-preparation processes. In the horizontal task, the Simon effect decays over time and pre-activation occurs above the motor cortex ipsilateral to the stimulus. In contrast, the Simon effect does not decay over time and no early incorrect LRP deflection is observed in the vertical task. These findings suggest that typical activation accounts can fit only the horizontal Simon effect, while a translation explanation is more suitable for the vertical Simon effect.     

Coping responses and problem appraisal in Spanish adolescents

This study uses Moos's Coping Responses Inventory (Youth Form, 1993) to examine coping behavior in Spanish adolescents. 1362 adolescents were recruited from the metropolitan area of Barcelona, Spain. All subjects were in high school and ages 12 to 16 years. The socio-economic status was primarily middle class. Adolescents' coping behaviors were examined by sex and age, and the relationship between problem appraisal and choice of coping strategy was analyzed. Girls used more approach, avoidance, and behavioral responses than boys, especially Logical Analysis, Seeking Guidance and Support, and Emotional Discharge strategies. At older ages, Logical Analysis and Emotional Discharge became more frequent in girls and Cognitive Avoidance less frequent in boys. The results also suggest that problem appraisal has only a limited effect on the selection of coping strategies and that only few strategies are related to the problems' outcomes.     

The Dubowitz neurological examination of the full-term newborn

In an ideal world, each neonate should have a comprehensive neurological examination but in practice this is often difficult. In this review we will describe what a routine neurological evaluation in the full-term neonate should consist of and how the Dubowitz examination is performed. The examination has been used for over 20 years and can be easily performed in a short time as the recording sheet provides simple instructions together with simple diagrams to make the recording and the scoring easier. We will also indicate how the examination can be used to identify infants with neurological abnormalities, describing clinical signs which can help to differentiate infants with peripheral neuromuscular disorders from those with central nervous system involvement. The correlation between clinical and imaging findings in infants with neonatal brain lesions will also be reported. Finally we will briefly describe how and when to apply an optimality scoring system in a research setting.     

Age-related differences in familiarity and recollection: ERP evidence from a recognition memory study in children and young adults

Using event-related potentials (ERPs), we examined the relative contributions of familiarity and recollection to recognition memory for items and their study contexts in school-aged children and adults. Whereas adults were able to selectively accept target items and to reject familiar nontarget items in an exclusion task, this discrimination was more difficult for children, as was evident in the high false alarm rates to nontargets even when item memory was controlled for. The analysis of the adults’ ERPs revealed more flexible and task-appropriate retrieval mechanisms, as was evident in the correlates of familiarity, recollection, and nontarget retrieval, as well as in postretrieval evaluation. In contrast, children’s ERPs revealed a parietal old/new effect for targets taken as a putative correlate of recollection. These findings suggest that children rely predominantly on recollection during recognition judgments, even in the absence of efficient memory control processes. The latter processes enable adults to monitor and verify the retrieved information and to control nontarget retrieval in the service of adequate source memory performance.     

Sour Grapes: Transgenerational Family Pathology in the Hebrew Bible

An analysis of Bible stories about the patriarchs' treatment of their children reveals pathological family patterns, which reoccur in subsequent generations. The outcome of parental favoritism and of unhealthy coalitions is sibling rivalry, leading to hatred and to violence among the children. The transgenerational chain of pathologies is traced back to God's differential treatment of Cain and Abel and to the resultant murder. The legitimization of family pathologies by the biblical stories is discussed.     

“Change my selfie”: Relationships between self-objectification and selfie-behavior in young Italian women

Self-objectification is a pervasive phenomenon, related to specific socio-cultural context, that can lead to many psychological and interpersonal consequences. With the present study, we investigated the correlates of self-objectification in young Italian women analyzing both its traditional antecedents and its consequences for self-presentation on social network sites (SNS). A total of 676 Italian university female students completed a self-reported questionnaire on self-objectification, internalization of a thin-ideal and related influences, internalized sexism, self-esteem, SNS use, selfie-posting on SNS and selfies’ manipulation. Results indicated that media and peers, but not family pressures, were positively associated with thin-ideal internalization, which, in turn, was positively associated with self-objectification. Moreover, both sexism and self-esteem were significantly associated with self-objectification. Regarding self-objectification consequences for SNS usage, results revealed that self-objectification was positively associated with time spent on SNS, frequency of selfie-posting and selfie-editing. It was concluded that objectification theory can be extended into the context of image-related behaviors on SNS. Results suggest that young women with low self-esteem, traditional attitudes toward gender roles and high levels of internalization of thin-ideal may report high levels of self-objectification which, in turn, may be related to specific self-promotion behaviors on social media. The limitations of the present study, particularly in terms of sampling and implications for future research on selfie-behavior are discussed.     

Opioid mechanisms are involved in the disruption of arcaine-induced amnesia by context pre-exposure

Previous exposure to the training context disrupts glutamatergic N-methyl-d-aspartate receptor (NMDAr) antagonist-induced amnesia, indicating that novelty is necessary for such an amnestic effect. While there are reports that novelty-related release of opioids cause amnesia, no study has addressed whether the amnestic effect of NMDAr antagonists involve opioid mechanisms. In this study we investigated whether pharmacological manipulation of the opioid system immediately after context pre-exposure alters the amnestic effect of arcaine, a NMDAr antagonist. Adult male Wistar rats were habituated (pre-exposed) to a fear conditioning training apparatus or to a different context (open field). Immediately after pre-exposure, animals were injected with saline or naloxone (0.5 mg/kg, i.p.) or anti-beta-endorphin antibody (1:500, i.c.v.). Forty eight hours after pre-exposure session, all animals were subjected to fear conditioning acquisition protocol and saline or arcaine (30 mg/kg, i.p.) was administered immediately after training. Testing was carried out 24 h later, and freezing responses due to re-exposure to the training apparatus were recorded. Pre-exposure to the training apparatus prevented the impairment of memory induced by post-training arcaine. Administration of naloxone or anti-beta-endorphin antibody, immediately after pre-exposure to the training apparatus, reinstated the amnesic effect of post-training arcaine. The results suggest that endogenous opioid mechanisms are involved in the pre-exposure-induced loss of the amnestic effect of arcaine.
