Evidence for a sensitive period for acculturation: younger immigrants report acculturating at a faster rate

Though recent adult immigrants often seem less acculturated to their new society than people who immigrated as children, it is not clear whether this difference is driven by duration of exposure or exposure during a sensitive developmental period. In a study aimed at disambiguating these influences, community and student samples of Hong Kong immigrants to Vancouver, Canada, completed the Vancouver Index of Acculturation, a measure that assesses respondents' identification with their mainstream and heritage cultures. A longer duration of exposure was found to be associated with greater identification with Canadian culture only at younger ages of immigration, but not at later ages of immigration. Conversely, identification with Chinese culture was unaffected by either age of immigration or length of exposure to Canadian culture. These findings provide evidence for a sensitive period for acculturation: People are better able to identify with a host culture the longer their exposure to it, but only if this exposure occurs when they are relatively young.     

The dud-alternative effect in memory for associations: Putting confidence into local context

When participants are asked to provide confidence judgments for each provided alternative in a multiple-choice memory task, such judgments are inflated if the assessed alternatives are accompanied by an implausible (dud) alternative. This finding, termed the dud-alternative effect, has been recently documented in a memory setting with a lineup procedure (Charman, Wells, & Joy, Law & Human Behavior 35:479–500 2011). In the present study, we developed a novel paradigm to investigate the dud-alternative effect in memory. The paradigm utilizes a multiple-choice associative recognition task in which dud alternatives can be rejected on the basis of their unfamiliarity. In two experiments, we demonstrated a reliable dud-alternative effect with our novel procedure. The results demonstrated that the dud-alternative effect in episodic memory is not limited to tasks based on perceptual factors, but is a general phenomenon concerning confidence judgments.     

Feeling of knowing and restudy choices

Feeling-of-knowing judgments (FOK-Js) reflect people’s confidence that they would be able to recognize a currently unrecallable item. Although much research has been devoted to the factors determining the magnitude and accuracy of FOK-Js, much less work has addressed the issue of whether FOK-Js are related to any form of metacognitive control over memory processes. In the present study, we tested the hypothesis that FOK-Js are related to participants’ choices of which unrecallable items should be restudied. In three experiments, we showed that participants tend to choose for restudy items with high FOK-Js, both when they are explicitly asked to choose for restudy items that can be mastered in the restudy session (Exps. 1a and 2) and when such specific instructions are omitted (Exp. 1b). The study further demonstrated that increasing FOK-Js via priming cues affects restudy choices, even though it does not affect recall directly. Finally, Experiment 2 showed the strategy of restudying unrecalled items with high FOK-Js to be adaptive, because the efficacy of restudy is greater for these items than for items with low FOK-Js. Altogether, the present findings underscore an important role of FOK-Js for the metacognitive control of study operations.     

Tell Me Your Name and I'll Tell You How Creative Your Work Is: Author's Name and Gender as Factors Influencing Assessment of Products' Creativity in Four Different Domains

The main goal of this study was to examine the effects of authors’ name and gender on judges’ assessment of product creativity in 4 different domains (art, science, music, and poetry). A total of 119 participants divided into 5 groups assessed products signed with a fictional author's name (unique vs. typical, male vs. female) or in an anonymous condition. It was observed that depending on the domain, the uniqueness of the author's name and her or his gender was associated with the assessment of creativity of the product. A poem and painting signed with an unusual name and a piece of music whose authorship was attributed to a man with a unique name were assessed as especially creative. In case of scientific theory, works attributed to men were assessed as significantly more creative than those of women. The results are discussed in light of the attributional approach to creativity.     

Both differences in encoding processes and monitoring at retrieval reduce false alarms when distinctive information is studied

ABSTRACT

Recent research has provided evidence for memory modifications when a post-reactivation treatment (e.g., drugs, new learning) interferes with the memory re-stabilisation (reconsolidation) process. This finding contradicts the long-standing consolidation theory and has high practical and theoretical implications. With an object-learning paradigm, it was shown that episodic memory is highly susceptible to interfering material presented after its reactivation [Hupbach, A., Gomez, R., Hardt, O., &; Nadel, L. (2007). Reconsolidation of episodic memories: A subtle reminder triggers integration of new information. Learning &; Memory, 14, 47–53. doi:10.1101/lm.365707]. The reactivation of a learned list (List 1) before a second learned list (List 2) led to intrusion errors from List 2 when trying to recall List 1, but not vice-versa. Their work has been widely cited and their findings have been explained according to reconsolidation theory. For the first time, we systematically explored the role of retrieval context as an alternative explanation for Hupbach’s results. Our results showed that the intrusion effect occurs independently of the retrieval context (Experiment 1). Additionally, even when the intrusion rate probability is increased (i.e., List 1 memory test is performed in the List 2 learning context), the groups that did not reactivate the original list did not commit intrusion errors (Experiment 2). In sum, we found that the intrusion effect critically depends on the presence of reactivation, discarding alternative interpretations of the results.     

Big Five Personality Traits as the Predictors of Creative Self‐Efficacy and Creative Personal Identity: Does Gender Matter?

The aim of this study was to examine the relation of the Big Five personality factors to two self‐concept variables of growing importance in creativity literature: creative self‐efficacy (CSE) and creative personal identity (CPI). The analysis, conducted on a large (N = 2674, 49.6% women) and varied‐in‐age (15–59 years old) nationwide sample of Poles, using the structural equation model, demonstrated that personality factors are responsible for 23% of CSE and 21% of CPI variances. CSE and CPI were associated with all five personality dimensions: positively with Openness to Experience, Extraversion and Conscientiousness, negatively with Neuroticism and Agreeableness. The separate analyses conducted on men and women showed the differences among the predictors of CSE and CPI. Although Openness to Experience, Conscientiousness, and Neuroticism predicted CSE among both men and women, Extraversion was positively and Agreeableness negatively related to women's CSE. Conscientiousness was positively related to CPI only among men, and Agreeableness was negatively related to it only among women. Extraversion, Neuroticism, and Openness predicted CPI in the same manner among men and women.     

An Evolutionary Approach Toward Exploring Altered States of Consciousness,Mind–Body Techniques,and Non-Local Mind

Humans are a part of the complex system including both natural and cultural-technological environment. Evolution of this system included self-amplifying feedbacks that lead to the appearance of human conscious mind. We describe the current state of the understanding of human brain evolution that stresses neurohormonal and biochemical changes rather than simple increase of anatomical substrate for the mind. It follows that human brain is strongly influenced by the state of the body and may operate at various levels of consciousness depending on its biochemical environment created by ingestion of various substances and by specific physical activities. Through the study of the widespread phenomenon of shamanism that uses mind-altering practices we argue that altered states of consciousness and non-local minds are not only real phenomena, but that they are products of natural evolution, valuable for human survival and development. Consideration of altered states of consciousness and broadening of the framework for understanding brain function beyond mechanistic interpretations is necessary to further develop human adaptations and provide a better way of fitting humans as parts of the interconnected system into the global and universal patterns.     

Psychometric properties of the children's atypical development scale

The Children's Atypical Development Scale (CADS) is a 53-item rating scale designed to measure unusual behaviors in children. Principal-factor analysis on a clinic-referred and pediatric sample of 474 children resulted in a four-factor solution: Communication Deficits, Lability, Social Relatedness Deficits, and Preoccupation. The CADS is internally consistent and has adequate temporal stability. CADS factor scores were differentially associated with parent and teacher rating scales, IQ, and Continuous Performance Test errors. The scale shows promise as a clinical and research tool for assessing atypical behaviors associated with pervasive developmental disorder and other neurobehavioral disorders.This research was supported in part by a grant from the Smart Family Foundation. The authors are grateful to James P. O'Donnell, Catherine Lord, and Frank A. Zelko for their comments on an earlier draft.

Greater Male Variability in Creativity Outside the WEIRD World

Recent studies in creativity literature have demonstrated higher variability of creative ability between males and females, despite the lack of systematic sex differences in average scores on creativity tests. However, little is known about the causes of this variability and its generalizability beyond industrialized societies. This study presents the first evidence of the greater male variability in a sample of nonindustrialized, traditional Meru people residing in Kenya, Africa. The effect size of this difference was even greater than that reported in the majority of studies conducted on industrialized populations. Implications of these findings are discussed.
