Effects of making errors in learning a foreign language

ABSTRACT

Kornell, Hays, and Bjork ([2009]. Unsuccessful retrieval attempts enhance subsequent learning. Journal of Experimental Psychology: Learning, Memory, and Cognition, 35, 989–998) showed that incorrect guesses do not necessarily harm and might even improve the retention of information on a subsequent test. We sought to replicate the finding using educationally relevant stimuli. In two experiments, our participants either translated sentences in a foreign language receiving immediate feedback (errorful condition), or copied and studied the correct translation (errorless condition). After this training phase, a final test with the same sentences showed that translating sentences wrongly during training did not lower the accuracy of the errorful as compared to the errorless condition. Overall there was evidence that errorful training produced superior learning of the meaning and grammar of the foreign language sentences. The results support the idea that search processes activate a greater network of related knowledge in the errorful than in the errorless condition.     

Glycosylated Hemoglobin Level,Race/Ethnicity,and Cognition in Midlife and Early Old Age

Empirical evidence linking racial/ethnic differences in glycosylated hemoglobin levels (HbA1c) to cognitive function in midlife and early old age is limited. We use biomarker data from the Health and Retirement Study (HRS, 2006–2014), on adults 50–64 years at baseline (57–73 years by 2014), and fit multinomial logistic regression models to assess the association between baseline HbA1c, cognitive function (using Langa–Weir classifications) and mortality across 8 years. Additionally, we test for modification effects by race/ethnicity. In age- and sex-adjusted models high HbA1c level was associated with lower baseline cognition and higher relative risk ratios (RRR; vs. normal cognition) for cognitive impairment no dementia (CIND; RRR = 2.3; 95%CI = [1.38;3.84]; p < .01), and dementia (RRR = 4.00; 95%CI = [1.76;9.10]; p < .01). Adjusting for sociodemographic, behavioral risk factors, and other health conditions explained the higher RRR for CIND and attenuated the RRR for dementia by approximately 30%. HbA1c levels were not linked to the slope of cognitive decline, and we found no evidence of modification effects for HbA1c by race/ethnicity. Targeting interventions for glycemic control in the critical midlife period can protect baseline cognition and buffer against downstream development of cognitive impairment. This can yield important public health benefits and reductions in burdens associated with cognitive impairment, particularly among race/ethnic minorities who are at higher risk for metabolic diseases.     

Knowledge of Objective ‘Oughts’: Monotonicity and the New Miners Puzzle

In the classic Miners case, an agent subjectively ought to do what they know is objectively wrong. This case shows that the subjective and objective ‘oughts’ are somewhat independent. But there remains a powerful intuition that the guidance of objective ‘oughts’ is more authoritative—so long as we know what they tell us. We argue that this intuition must be given up in light of a monotonicity principle, which undercuts the rationale for saying that objective ‘oughts’ are an authoritative guide for agents and advisors.     

From rights to prerogatives

Deontologists believe in two key exceptions to the duty to promote the good: restrictions forbid us from harming others, and prerogatives permit us not to harm ourselves. How are restrictions and prerogatives related? A promising answer is that they share a source in rights. I argue that prerogatives cannot be grounded in familiar kinds of rights, only in something much stranger: waivable rights against oneself.     

Social cognitive predictors of peer acceptance at age 5 and the moderating effects of gender

In this study we examined the effects of social intelligence, empathy, verbal ability and appearance‐reality distinction on the level of peer acceptance, as well as the moderating role of gender. Participants were 98 five‐year‐old children (43 boys and 55 girls; mean age 5 years 3 months for boys and girls). Our results showed a main effect of social intelligence on peer acceptance, as well as several other effects that were moderated by gender: a significant and positive effect of verbal ability on social acceptance was found for boys; appearance‐reality distinction was found to have a positive effect on social acceptance in the case of girls; and although empathy had a significant positive effect on social acceptance for both boys and girls, this effect was more pronounced among boys. Our results suggest that abilities promoting peer acceptance are different for boys and girls.     

Differentiation of Self Predicts Life Satisfaction through Marital Adjustment

Abstract

Previous studies have documented the link between differentiation of self and life satisfaction. However, the underlying mechanisms explaining these associations are yet to be tested at the dyadic level. This study examined the mediating role of marital adjustment in the association between differentiation of self and life satisfaction among 113 Turkish heterosexual married couples (N?=?226). Analyses using the Common Fate Model demonstrated that differentiation of self was associated with higher levels of marital adjustment and life satisfaction, such that marital adjustment was positively associated with life satisfaction, and in turn, marital adjustment fully mediated this association. Implications are discussed for clinicians and cross-cultural researchers who seek to promote greater life satisfaction by targeting both differentiation and marital adjustment.     

The missing link between faces and names: Evidence from Alzheimer's disease patients

Retrieval of proper names is a cause of concern and complaint among elderly adults and it is an early symptom of patients suffering from neurodegenerative diseases such as Alzheimer's disease (AD). While it is well established that AD patients have deficits of proper name retrieval, the nature of such impairment is not yet fully understood. Specifically, it is unknown whether this deficit is due to a degradation of the links between faces and proper names, or due to deficits in intentionally accessing and retrieving proper names from faces. Here, we aim to investigate the integrity of the links between famous faces and proper names in AD while minimizing the impact of the explicit retrieval. We compare the performances of AD patients and elderly controls in a face-name priming task. We assess the integrity of the link between faces and names at two different levels: identity level - the name and face belong to the same person; and semantic level - the name and face belong to the same category (e.g., politicians). Our results reveal that AD patients compared with controls show intact semantic priming but reduced priming for person identity. This suggests that the deficits in intentionally retrieving proper names in AD are the result of a partial disruption of the network at the identity level, i.e., the links between known faces and proper names.
