Realism in confidence judgements of performance based on implicit learning

In two experiments we employed calibration methods to investigate the realism of participants' confidence ratings of their own classification performance based on knowledge acquired after training on an artificial grammar. In Experiment 1 participants showed good realism (but overconfidence) for grammatical strings but very poor realism for non-grammatical strings. Method of training (string repetition in writing or mere exposure) did not affect the realism. Furthermore, the participants underestimated their overall performance. In Experiment 2, using a more complex grammar and controlling for two types of associative chunk-strength, participants showed good realism (but still overconfidence) for both letter and symbol strings, irrespective of grammaticality. Together, these experiments show that implicit learning can give rise to knowledge products that are associated with fairly realistic meta-knowledge. It is argued that both the zero-correlation criterion and the guessing criterion are misplaced when used to define implicit knowledge; two reasons being that confidence judgements may be affected both by implicit knowledge and by inferences.     

The applied value of collaborative memory research in aging: Behavioral and neural considerations

Our aim in this paper is to bring attention to the applied value of collaborative memory research in aging. At this time, much collaborative memory research focuses on the negative effects of collaboration in younger adults, and is primarily basic in nature. Here, we highlight the positive effects of collaboration that have received less attention, with a particular emphasis on the applied value of these effects in older adults. We first review studies to show that recalling in a group improves later individual recall and reduces memory errors in older adults. We then outline a four-step approach towards bridging laboratory and applied collaborative memory research, which involves: (1) complementing traditional paradigms with more ecologically valid paradigms, (2) evaluating these paradigms in applied settings, (3) adapting these paradigms for use with cognitively intact and cognitively impaired populations, and (4) modifying these paradigms to examine the neural systems that operate during collaborative recall.     

Adolescent mental health in Japan and Russia: The role of body image,bullying victimisation and school environment

This study examined associations between self-reported mental health problems, body image, bullying victimisation and school safety in large adolescent samples in Japan and Russia, considering the effects of gender, culture and their interactions. In both Japan and Russia, girls reported a greater number of mental health problems, less bullying victimisation and much higher body dissatisfaction than boys did. Japanese adolescents rated themselves higher on total difficulties, reported less body dissatisfaction and bullying victimisation, and rated their school safety lower than that of Russian youths. Cross-cultural differences in total difficulties and body image were qualified by gender. Body dissatisfaction, bullying victimisation and school safety all independently contributed to adolescent mental health problems. The protective effect of school safety on total difficulties was larger for girls than for boys; the strength of the association between bullying victimisation and adolescent mental health problems differed across genders and cultures. The findings indicate a need for a cross-cultural approach and provide a strong basis for targeted interventions that seek to improve adolescent mental health.     

Investigation of Body Comparison Among Adolescent Girls1

Grade differences in appearance and nonappearance social comparisons, and targets for body comparison were examined in adolescent girls. A model describing potential contributors to, and consequences of, body comparison tendency was examined. Girls (n= 545) completed measuring social comparisons, targets for comparisons, dieting in response to comparisons, body attitudes, eating patterns, psychological variables, height, and weight. Appearance and nonappearance social comparisons increased with age. Girls reported comparing their bodies most frequently with peers and fashion models. Body comparison tendency was significantly predicted by: importance of thinness, internalization of socio‐cultural ideal, friend concern with weight, body image instability, competitiveness, grade, public self‐consciousness, perfectionism, and family concern with weight. Predictors of dieting in response to body comparison were also explored.     

Competition Between Outcomes

In both Pavlovian conditioning and human causal judgment, competition between cues is well known to occur when multiple cues are presented in compound and followed by an outcome. More questionable is the occurrence of competition between outcomes when a single cue is followed by multiple outcomes presented in compound. In the experiment reported here, we demonstrated blocking (a type of stimulus competition) between outcomes. When the cue predicted one outcome, its ability to predict a second outcome that was presented in compound with the first outcome was reduced. The procedure minimized the likelihood that the observed competition between outcomes arose from selective attention. The competition between outcomes that we observed is problematic for contemporary theories of learning.

Lifelong minority religion: routines and reflexivity: A Bourdieuan perspective on the habitus of elderly Finnish Orthodox Christian women

Applications of the concept of habitus to research on religion have increased in recent decades. At present, Pierre Bourdieu's interpretation of the concept is perhaps the most well known. Nevertheless, it has also met with criticism. This article utilizes Bourdieuan theorizations to discuss the habitus of elderly Finnish Orthodox Christian women. The author examines the women's dispositions in relation to their changing minority position within Finnish society, and identifies the dynamic between reflexivity and routine practice as being central to their religion. The analysis demonstrates the value of Bourdieu's understanding of habitus when studying the long-term effects of social power on subjectivity – as reflected, for instance, in lifelong minority religion. The author argues, moreover, that contrary to the claims of many critics, Bourdieu's approach is suitable for inquiries into the conscious dimensions of practicing, in so far as these are conceived of as grounded in individuals’ past and present conditions of religious practice.
