Determiner Primes as Facilitators of Lexical Retrieval in English

Gender priming studies have demonstrated facilitation of noun production following pre-activation of a target noun??s grammatical gender. Findings provide support for models in which syntactic information relating to words is stored within the lexicon and activated during lexical retrieval. Priming effects are observed in the context of determiner plus noun phrase production. Few studies demonstrate gender priming effects in bare noun production (i.e., nouns in isolation). We investigated the effects of English determiner primes on bare mass and count noun production. In two experiments, participants named pictures after exposure to primes involving congruent, incongruent and neutral determiners. Facilitation of noun production by congruent and neutral determiner primes was found in both experiments. The results suggest that noun phrase syntax is activated in lexical retrieval, even when not explicitly required for production. Post hoc analysis of the relative frequency of congruent and incongruent prime-target pairs provides support for a frequency-based interpretation of the data.     

Comparing pluralities

What does it mean to compare sets of objects along a scale, for example by saying “the men are taller than the women”? We explore comparison of pluralities in two experiments, eliciting comparison judgments while varying the properties of the members of each set. We find that a plurality is judged as “bigger” when the mean size of its members is larger than the mean size of the competing plurality. These results are incompatible with previous accounts, in which plural comparison is inferred from many instances of singular comparison between the members of the sets (Matushansky &; Ruys, 2006). Our results suggest the need for a type of predication that ascribes properties to plural entities, not just individuals, based on aggregate statistics of their members. More generally, these results support the idea that sets and their properties are actively represented as single units.     

Noise effects on human performance: a meta-analytic synthesis

Noise is a pervasive and influential source of stress. Whether through the acute effects of impulse noise or the chronic influence of prolonged exposure, the challenge of noise confronts many who must accomplish vital performance duties in its presence. Although noise has diffuse effects, which are shared in common with many other chronic forms of stress, it also exerts its own specific influences on various forms of cognitive and motor response. We present a quantitative evaluation of these influences so that their harmful effects can be mitigated, their beneficial effects exploited, and any residual effects incorporated and synthesized into selection, training, and design strategies to facilitate human performance capacities. Predictions of single and joint moderator effects were made on the basis of major theories of noise and performance, specifically those explanations based on arousal, masking, or cognitive-resource mechanisms. These predictions were tested through moderator analyses of effects as a function of task type, performance measure, noise type and schedule, and the intensity and duration of exposure. Observed outcome effects (797 effect sizes derived from 242 studies) varied as a function of each of these moderators. Collective findings identified continuous versus intermittent noise, noise type, and type of task as the major distinguishing characteristics that moderated response. Mixed evidence was obtained for the traditional arousal and masking explanations for noise effects. The overall pattern of findings was most consistent with the maximal adaptability theory, a mental-resource-based explanation of stress and performance variation.     

Attitudes of Mothers of Children with Down Syndrome Towards Noninvasive Prenatal Testing

Noninvasive prenatal testing (NIPT) allows for highly sensitive detection of Down syndrome early in pregnancy with no risk of miscarriage, therefore potentially increasing the number of pregnancies identified with Down syndrome. This study assesses how mothers of children with Down syndrome perceive NIPT, especially the impact they think it will have on their families and other families with children who have Down syndrome. Seventy-three self-reported mothers of children with Down syndrome responded to an anonymous online survey emailed to, and posted on, message boards of various Down syndrome support groups and networks. Data analysis included chi-square tests and thematic analysis. Fifty-nine percent of respondents indicated they would use NIPT in the future; respondents who had not used prenatal testing in the past were significantly less likely to report interest in using NIPT in the future than those who had prenatal testing previously (p?MOST important factor. They also highlight the need to provide a diagnosis of Down syndrome in a balanced and objective manner.     

The frequency of excess success for articles in Psychological Science

Recent controversies have questioned the quality of scientific practice in the field of psychology, but these concerns are often based on anecdotes and seemingly isolated cases. To gain a broader perspective, this article applies an objective test for excess success to a large set of articles published in the journal Psychological Science between 2009 and 2012. When empirical studies succeed at a rate much higher than is appropriate for the estimated effects and sample sizes, readers should suspect that unsuccessful findings have been suppressed, the experiments or analyses were improper, or the theory does not properly account for the data. In total, problems appeared for 82 % (36 out of 44) of the articles in Psychological Science that had four or more experiments and could be analyzed.     

Is state-trace analysis an appropriate tool for assessing the number of cognitive systems?

There is now much evidence that humans have multiple memory systems, and evidence is also building that other cognitive processes are mediated by multiple systems. Even so, several recent articles have questioned the existence of multiple cognitive systems, and a number of these have based their arguments on results from state-trace analysis. State-trace analysis was not developed for this purpose but, rather, to identify data sets that are consistent with variation in a single parameter. All previous applications have assumed that state-trace plots in which the data fall on separate curves rule out any model in which only a single parameter varies across the two tasks under study. Unfortunately, this assumption is incorrect. Models in which only one parameter varies can generate any type of state-trace plot, as can models in which two or more parameters vary. In addition, it is straightforward to show that both single-system and multiple-systems models can generate state-trace plots that are considered in the literature to be consistent with either one or multiple cognitive systems. Thus, without additional information, there is no empirical state-trace plot that supports any inferences about the number of underlying parameters or systems.     

Chinese and South Asian Conceptions of the Good Life and Personal Narratives

Are cultural visions of a good life reflected in how people narrate the personal past? Do they tend to emphasize experiences that correspond to their cultural commitments about what is important and worthwhile in the life they are hoping to live? To examine this possibility, Chinese and South Asian international students at a Canadian university were compared on the content of their narrative accounts of their post-arrival experiences. Predictions about how these groups differ in the prevalence of various topical categories were made on the basis of previous research on cultural conceptions of a good life. A majority of the predictions were confirmed, supporting the general claim that Chinese tend more toward practical and prudential concerns, and less toward spiritual and beneficent concerns, than do South Asians.     

Goal complexes: Integrating achievement goals as standards and self-attributed motives as reasons underlying goal pursuit

Goal complexes, which are formed by pairing standards of competence strivings with their underlying reasons, are essential to an understanding of achievement goal regulation. This paper examines goal complexes that cross other-approach and other-avoidance goals with the approach-avoidance dimensions of Big Three motives as underlying reasons. 220 undergraduates participated in Study 1 which developed and validated the Self-Attributed Motive Scale to measure hope of success, fear of failure, hope of affiliation, fear of rejection, hope of power, and fear of loss of power. Additionally, 235 undergraduates participated in Study 2 where goal complexes were created by crossing the motive items developed in Study 1 with other-approach and other-avoidance goals. The predictive utility of the resultant goal complexes was examined in relation to positive well-being (positive learning-related emotions and engagement), negative well-being (negative learning-related emotions and burnout), and academic buoyancy. The contributions of the studies to the self-attributed motive and goal complex literatures are discussed.
