Counter-stereotypic beliefs in math do not protect school girls from stereotype threat

The threat of being negatively stereotyped in math impairs performance of highly qualified females on difficult math tests, a phenomenon known as “stereotype threat”—ST. Perhaps more alarmingly, recent studies based on unselective samples of elementary-, middle-, and high-school students show that ST also operates in girls from the general population. Here we offer first evidence that ST does operate (with large effect sizes) even in middle-school girls who deny the negative gender stereotype. Children’s beliefs about the two genders math ability, therefore, do not necessarily moderate their susceptibility to ST, an important issue that remained unclear so far. This new finding is also of great practical significance: School girls’ counter-stereotypic beliefs cannot be taken as sufficient evidence for deciding whether the struggle against ST is or is not needed. Appropriate interventions should be the default option when aiming for true gender equality in math and science achievements.     

Gender Differences in the Nature,Antecedents and Consequences of Parental Burnout

Sex Roles - Parenthood remains one of the most gender-typed social roles in adulthood. Given gender inequality in parenting, it has been very surprising to find that parental burnout affects both...     

When political expertise moderates the impact of scandals on young adults' judgments of politicians

This short note investigated how expertise in a political scandal moderates whether the activation of this scandal produces assimilation in the evaluation of politicians in general and contrast in the evaluation of specific politicians. It was hypothesized that participants with a rich knowledge about the scandal would display the assimilation and contrast effects whereas those with a poorer knowledge would not. Results tended to support this prediction, suggesting that the impact on judgment of a specific context depends on the amount of knowledge participants possess about this context.

Regret and quality of life across the adult life span: the influence of disengagement and available future goals

Two studies examined the associations between life regrets and indicators of quality of life across the adult life span. Given that opportunities to undo regrets decline with age, regret intensity was expected to be inversely associated with subjective well-being and health among older adults. In addition, the research explored protective factors that have the potential to reduce older adults' regret intensity. It was suggested that being disengaged from undoing the consequences of regrets and having many future goals available may reduce older adults' intensity of regret and thereby contribute to a better quality of life. Across both studies, the findings demonstrate that older adults perceived reduced opportunities to undo the consequences of their regrets and that regret intensity predicted a reduced quality of life only among older adults. Furthermore, the findings support the adaptive value of disengagement and available future goals for managing life regrets in older adults.     

When internalization leads to automatization: The role of self-determination in automatic stereotype suppression and implicit prejudice regulation

Recent evidence suggests that self-determined prejudice regulation is negatively related to both self-reported prejudice and automatic racial bias. However, the social-cognitive processes involved in this association have not yet been examined. Thus, the current project sought to test the ‘internalization-automatization hypothesis’, that is, to assess the extent to which prejudice regulation is automatic for those high and low in self-determined motivation to regulate prejudice. To this end, two different experimental paradigms were used. In Experiment 1 (N = 84), differences in the automatic activation and application of stereotypes were assessed for those high and low in self-determined prejudice regulation. As expected, both types of prejudice regulators showed similar stereotype activation. However, only self-determined individuals inhibited the application of stereotypes following a prime. Experiment 2 (N = 134), assessed the impact of self-regulatory depletion on the regulation of implicit prejudice. As anticipated, for the self-determined regulators, prejudice regulation did not vary between depleted and non-depleted individuals. However, when non-self-determined prejudice regulators were depleted, prejudice increased, relative to non-depleted controls. Results are discussed in terms of an increased understanding of prejudice regulation through self-determination. Evidence of the automatization of self-determined prejudice regulation offers promising implications for the reduction of prejudice.

Frequency-range discriminations and absolute pitch in black-capped chickadees (Poecile atricapillus), mountain chickadees (Poecile gambeli), and zebra finches (Taeniopygia guttata)

The acoustic frequency ranges in birdsongs provide important absolute pitch cues for the recognition of conspecifics. Black-capped chickadees (Poecile atricapillus), mountain chickadees (Poecile gambeli), and zebra finches (Taeniopygia guttata) were trained to sort tones contiguous in frequency into 8 ranges on the basis of associations between response to the tones in each range and reward. All 3 species acquired accurate frequency-range discriminations, but zebra finches acquired the discrimination in fewer trials and to a higher standard than black-capped or mountain chickadees, which did not differ appreciably in the discrimination. Chickadees' relatively poorer accuracy was traced to poorer discrimination of tones in the higher frequency ranges. During transfer tests, the discrimination generalized to novel tones when the training tones were included, but not when they were omitted.     

Tracking irregular morphophonological dependencies in natural language: evidence from the acquisition of subject-verb agreement in French

This study examines French-learning infants’ sensitivity to grammatical non-adjacent dependencies involving subject-verb agreement (e.g., le/les garçons lit/lisent ‘the boy(s) read(s)’) where number is audible on both the determiner of the subject DP and the agreeing verb, and the dependency is spanning across two syntactic phrases. A further particularity of this subsystem of French subject-verb agreement is that number marking on the verb is phonologically highly irregular. Despite the challenge, the HPP results for 24- and 18-month-olds demonstrate knowledge of both number dependencies: between the singular determiner le and the non-adjacent singular verbal forms and between the plural determiner les and the non-adjacent plural verbal forms. A control experiment suggests that the infants are responding to known verb forms, not phonological regularities. Given the paucity of such forms in the adult input documented through a corpus study, these results are interpreted as evidence that 18-month-olds have the ability to extract complex patterns across a range of morphophonologically inconsistent and infrequent items in natural language.     

Neuropsychological Findings in Two Children Diagnosed with Hamartoses: Evidence of a NLD Phenotypic Profile

Hamartoses (HM) are defined as disorders involving nonneoplastic tissue overgrowth. Studies have examined the neuropsychological profiles of children with common HM, such as neurofibromatosis type 1. Limited information is known regarding neuropsychological profiles of rare HM such as Osteochondromatosis Syndrome (OS) and Klippel-Trenaunay Syndrome (KTS). The current investigation is, to our knowledge, the first attempt to define the cognitive phenotypes in two boys with OS and KTS. Results revealed significantly greater impairments involving sensorimotor and visuospatial skills, while verbal memory and language skills appeared relatively preserved. Significant neurobehavioral problems and marked social difficulties were evident. These findings suggest that these syndromes are on a Nonverbal Learning Disorder (NLD) continuum, with varying degrees of severity.     

The memory remains: long-term vocal recognition in Australian sea lions

The ability to recognize other individuals plays an important role in mediating social interactions. As longitudinal studies are challenging, there is only limited evidence of long-term memory of individuals and concepts in mammals. We examined the ability of six wild Australian sea lions to discriminate between the voice of their mother and another adult female, both while they were dependent on their mother and when they were independent, 2 years after weaning. Here, we show that even after a long period of independence, juveniles retain the ability to identify their mother’s voice. Both when dependent and independent, animals showed stronger responses to maternal calls than to the calls of another female. This demonstration of recognition provides rare evidence of the long-term memory capabilities of wild mammals.     

Generative connectionist networks and constructivist cognitive development

This article presents a novel computational framework for modeling cognitive development. The new modeling paradigm provides a language with which to compare and contrast radically different facets of children's knowledge. Concepts from the study of machine learning are used to explore the power of connectionist networks that construct their own architectures during learning. These so-called generative algorithms are shown to escape from Fodor's (1980) critique of Constructivist development. We describe one generative connectionist algorithm (cascade-correlation) in detail. We report on the successful use of the algorithm to model cognitive development on balance scale phenomena; seriation; the integration of velocity, time, and distance cues; prediction of effect sizes from magnitudes of causal potencies and effect resistances; and the acquisition of English personal pronouns. The article demonstrates that computer models are invaluable for illuminating otherwise obscure discussions.
