On the Consistency of a Plural Theory of Frege’s <Emphasis Type="Italic">Grundgesetze</Emphasis>

PG (Plural Grundgesetze) is a predicative monadic second-order system which is aimed to derive second-order Peano arithmetic. It exploits the notion of plural quantification and a few Fregean devices, among which the infamous Basic Law V. In this paper, a model-theoretical consistency proof for the system PG is provided.     

A method for quantifying focused versus overview behavior in AOI sequences

We present a new measure for evaluating focused versus overview eye movement behavior in a stimulus divided by areas of interest. The measure can be used for overall data, as well as data over time. Using data from an ongoing project with mathematical problem solving, we describe how to calculate the measure and how to carry out a statistical evaluation of the results.     

Girls' math performance under stereotype threat: the moderating role of mothers' gender stereotypes

Previous research on stereotype threat in children suggests that making gender identity salient disrupts girls' math performance at as early as 5 to 7 years of age. The present study (n = 124) tested the hypothesis that parents' endorsement of gender stereotypes about math moderates girls' susceptibility to stereotype threat. Results confirmed that stereotype threat impaired girls' performance on math tasks among students from kindergarten through 2nd grade. Moreover, mothers' but not fathers' endorsement of gender stereotypes about math moderated girls' vulnerability to stereotype threat: performance of girls whose mothers strongly rejected the gender stereotype about math did not decrease under stereotype threat. These findings are important because they point to the role of mothers' beliefs in the development of girls' vulnerability to the negative effects of gender stereotypes about math.     

Long life to emotions: emotional response categorisation across the lifespan

People perceive and organise their social world on the basis of their previous semantic knowledge as well as on the basis of their emotional responses. We tested the hypothesis that emotional response categorisation, namely the tendency to group stimuli on the basis of the emotion they evoke, increases across the lifespan. Young and older adults were asked to categorise target words and either conceptual or emotional response similarity could be used to perform the task. Results showed that older adults were more likely than younger adults to rely on emotional equivalence to categorise stimuli. In addition, current affective state was significantly related to emotional response categorisation. These findings are discussed in relation to recent models that propose a prominent role for emotions in the social life of older adults.     

Unable to resist temptation: How self-control depletion promotes unethical behavior

Across four experimental studies, individuals who were depleted of their self-regulatory resources by an initial act of self-control were more likely to “impulsively cheat” than individuals whose self-regulatory resources were intact. Our results demonstrate that individuals depleted of self-control resources were more likely to behave dishonestly (Study 1). Depletion reduced people’s moral awareness when they faced the opportunity to cheat, which, in turn, was responsible for heightened cheating (Study 2). Individuals high in moral identity, however, did not show elevated levels of cheating when they were depleted (Study 3), supporting our hypothesis that self-control depletion increases cheating when it robs people of the executive resources necessary to identify an act as immoral or unethical. Our results also show that resisting unethical behavior both requires and depletes self-control resources (Study 4). Taken together, our findings help to explain how otherwise ethical individuals predictably engage in unethical behavior.     

Anxiety, advice, and the ability to discern: feeling anxious motivates individuals to seek and use advice

Across 8 experiments, the influence of anxiety on advice seeking and advice taking is described. Anxious individuals are found to be more likely to seek and rely on advice than are those in a neutral emotional state (Experiment 1), but this pattern of results does not generalize to other negatively valenced emotions (Experiment 2). The relationships between anxiety and advice seeking and anxiety and advice taking are mediated by self-confidence; anxiety lowers self-confidence, which increases advice seeking and reliance upon advice (Experiment 3). Although anxiety also impairs information processing, impaired information processing does not mediate the relationship between anxiety and advice taking (Experiment 4). Finally, anxious individuals are found to fail to discriminate between good and bad advice (Experiments 5a-5c), and between advice from advisors with and without a conflict of interest (Experiment 6).     

Coparenting interactions observed by the prenatal lausanne trilogue play: An Italian replication study

The infant–parent interaction is the focus of interest on early interactive relational models in the triadic perspective. This approach considers the mother–father–child interaction as the matrix of early competences, which start to develop well before delivery. This theoretical approach has generated an observation paradigm, the Lausanne Trilogue Play (LTP; E. Fivaz‐Depeursinge & A. Corboz‐Warnery, 1999). The aim of the study was to investigate (a) the psychometric characteristics of coding of the prenatal LTP procedure and their comparison with the Lausanne validation studies and (b) the characteristics of triadic interactions during pregnancy. Ninety‐eight nonreferred, primiparous families were recruited at childbirth courses. In addition to validated questionnaires, observational data were collected at the seventh month of pregnancy in the prenatal LTP. The collected data show good reliability of the LTP coding and a consistent factorial structure in line with the Lausanne validation studies (C. Carneiro, A. Corboz‐Warnery, & E. Fivaz‐Depeursinge, 2006; N. Favez et al., 2006). The Structure of the Play and the Intuitive Parenting Behaviors Scales seem the most representative dimensions in the prenatal period. Coparental abilities during pregnancy represent an interactive matrix for the construction of early family relations and may be considered as protective factors in the child's development of early triadic interactive abilities.     

Power,competitiveness, and advice taking: Why the powerful don’t listen

Four experiments test the prediction that feelings of power lead individuals to discount advice received from both experts and novices. Experiment 1 documents a negative relationship between subjective feelings of power and use of advice. Experiments 2 and 3 further show that individuals experiencing neutral and low levels of power weigh advice from experts and experienced advisors more heavily than advice from novices, but individuals experiencing high levels of power discount both novice and expert advice. Experiments 3 and 4 demonstrate that this tendency of individuals experiencing high levels of power to discount advice from experts and novices equally is mediated by feelings of competitiveness (Experiment 3) and confidence (Experiments 3 and 4). Finally, Experiment 4 shows that inducing high power individuals to feel cooperative with their advisors can mitigate this tendency, leading them to weigh expert advice more heavily than advice from novices. Theoretical and practical contributions are discussed.     

Reading aloud: The cumulative lexical interference effect

Picture naming shows a cumulative semantic interference effect: Latency for naming a target picture increases as a function of the number of pictures semantically similar to the target that have previously been named (Howard, Nickels, Coltheart, & Cole-Virtue, Cognition 100:464-482, 2006). Howard and colleagues, and also Oppenheim, Dell, and Schwartz (Cognition 114:227-252, 2010), argued that this occurs because of the joint presence in the picture-naming system of three critical properties: shared activation, priming, and competition. They also discussed the possibility that whenever any cognitive system possesses these three properties, a cumulative similarity-based interference effect from repeated use of that cognitive system will occur. We investigated this possibility by looking for a cumulative lexical interference effect when the task is reading aloud: Will the latency of reading a target word aloud increase as a function of the number of words orthographically/phonologically similar to the target that have previously been read aloud? We found that this was so. This supports the general idea that cumulative similarity-based interference effects will arise whenever any cognitive system that possesses the three key properties of shared activation, priming, and competition is repeatedly used.
