The existence of an "addictive" personality has been extensively debated. The current study investigated personality in male individuals with excessive alcohol consumption (n=100) in comparison to a population-based control group (n=131). The individuals with excessive alcohol consumption were recruited by advertisements in a regional daily newspaper and controls from a population based Swedish Twin Registry. Personality was assessed by the Karolinska Scales of Personality (KSP). Comparisons were made with normative data. Furthermore, by using a multivariate projection-based approach (Principal Component Analysis; PCA), hidden structures of traits and possible relationships among the individuals with excessive consumption and the controls was investigated. The individuals with excessive alcohol consumption as well as the controls had mean values within the normative range in all scales of the KSP. Moreover, the PCA analysis revealed no systematic between-group separation. Taken together, this result demonstrates that male individuals with excessive alcohol consumption do not have a personality different from that of a general population, which supports the notion of no "addictive personality". 相似文献

The present study examines age‐related differences between young and older adults in spatial mental representation derived from learning a realistic city map. A sample of 30 young (20–30‐years) and 30 older (60–72 years) adults learned a simplified map of a city; afterwards participants performed map‐drawing and pointing‐aligned and counter‐aligned tasks. Tasks measuring visuo‐spatial abilities were also administered to explore their relationship with map learning. Results showed an age‐related impairment in older adults in both map tasks, as well as in visuo‐spatial ones. Furthermore, performance on counter‐aligned pointing was poorer than on aligned pointing in young and older adults, and its relationship with visuo‐spatial abilities changed as a function of age group: The performance of counter‐aligned pointing in older adults was related to all visuo‐spatial abilities, and in young adults with perspective‐taking measures only.

Apolipoprotein receptors belong to an evolutionarily conserved surface receptor family that has intimate roles in the modulation of synaptic plasticity and is necessary for proper hippocampal-dependent memory formation. The known lipoprotein receptor ligand Reelin is important for normal synaptic plasticity, dendritic morphology, and cognitive function; however, the in vivo effect of enhanced Reelin signaling on cognitive function and synaptic plasticity in wild-type mice is unknown. The present studies test the hypothesis that in vivo enhancement of Reelin signaling can alter synaptic plasticity and ultimately influence processes of learning and memory. Purified recombinant Reelin was injected bilaterally into the ventricles of wild-type mice. We demonstrate that a single in vivo injection of Reelin increased activation of adaptor protein Disabled-1 and cAMP-response element binding protein after 15 min. These changes correlated with increased dendritic spine density, increased hippocampal CA1 long-term potentiation (LTP), and enhanced performance in associative and spatial learning and memory. The present study suggests that an acute elevation of in vivo Reelin can have long-term effects on synaptic function and cognitive ability in wild-type mice. 相似文献

This study examined the relations of school-age children’s depressive symptoms, frontal EEG asymmetry, and maternal history
of childhood-onset depression (COD). Participants were 73 children, 43 of whom had mothers with COD. Children’s EEG was recorded
at baseline and while watching happy and sad film clips. Depressive symptoms were measured using parent-report of Children’s
Depression Inventory. The key findings are the interaction effects between baseline and film frontal EEG asymmetry on child
depressive symptoms. Specifically, relative right frontal EEG asymmetry while watching happy or sad film clip was associated
with elevated depressive symptoms for children who also exhibited right frontal EEG asymmetry at baseline. Results suggest
that right frontal EEG asymmetry that is consistent across situations may be an marker of depression-prone children. 相似文献

This study examined children's ability to use mutual eye gaze as a cue to friendships in others. In Experiment 1, following a discussion about friendship, 4-, 5-, and 6-year-olds were shown animations in which three cartoon children looked at one another, and were told that one target character had a best friend. Although all age groups accurately detected the mutual gaze between the target and another character, only 5- and 6-year-olds used this cue to infer friendship. Experiment 2 replicated the effect with 5- and 6-year-olds when the target character was not explicitly identified. Finally, in Experiment 3, where the attribution of friendship could only be based on synchronized mutual gaze, 6-year-olds made this attribution, while 4- and 5-year-olds did not. Children occasionally referred to mutual eye gaze when asked to justify their responses in Experiments 2 and 3, but it was only by the age of 6 that reference to these cues correlated with the use of mutual gaze in judgements of affiliation. Although younger children detected mutual gaze, it was not until 6 years of age that children reliably detected and justified mutual gaze as a cue to friendship. 相似文献

Attention-deficit/hyperactivity disorder (ADHD) has long been thought to reflect dysfunction of prefrontal-striatal circuitry, with involvement of other circuits largely ignored. Recent advances in systems neuroscience-based approaches to brain dysfunction have facilitated the development of models of ADHD pathophysiology that encompass a number of different large-scale resting-state networks. Here we review progress in delineating large-scale neural systems and illustrate their relevance to ADHD. We relate frontoparietal, dorsal attentional, motor, visual and default networks to the ADHD functional and structural literature. Insights emerging from mapping intrinsic brain connectivity networks provide a potentially mechanistic framework for an understanding of aspects of ADHD such as neuropsychological and behavioral inconsistency, and the possible role of primary visual cortex in attentional dysfunction in the disorder. 相似文献

The current study, utilizing data from the National Early Head Start Research and Evaluation Project (Love et al., 2005) explored the relationship between biological father presence and emotion regulation over toddlerhood among children from low‐income families. Conceptualizing biological father presence as a proxy for family role development, results are interpreted from a role development theoretical perspective. The latent growth curve model was compared based on child ethnoracial status (African American, Caucasian, Hispanic) and child gender. Consistent biological father presence was associated with toddlers’ regulatory development across toddlerhood, and this relationship was most robust among Caucasian toddlers as compared to African American toddlers. Findings for Hispanic toddlers were not significantly different from those of Caucasian or African American families. Results bolster the literature on father presence and child outcomes. Analyses address consistency in father presence as a proxy for coherent role development and define a link between consistent father presence and children's regulatory development, demonstrating ethnoracial differences which are likely attributed to the social construction of family roles. 相似文献

Making important decisions about health and safety often involves contemplating the regret that may arise if a decision turns out badly. Does anticipated regret decrease risky behaviors and promote precautionary behaviors? The present article reviews the role of anticipated regret in health and safety decisions by outlining findings from the most commonly researched topics. In line with an extended theory of planned behavior, the review concludes that anticipated regret generally predicts behavioral intentions, and intentions in turn influence health and safety behavior. The review discusses methodological recommendations and implications for interventions, and identifies unanswered questions and directions for future research. 相似文献
