Comprehending pronouns: a role for word-specific gender stereotype information

The research investigated how word-specific gender stereotype information can be used during language comprehension. In a rating study, the gender stereotypes for 405 noun and noun compounds were assessed. From these norms, 32 words strongly stereotyped to refer mostly to males and 32 words strongly stereotyped to refer mostly to females were selected and used in a reading experiment. Comprehenders read pairs of sentences. The subject of the first sentence was a gender stereotyped word (e.g., executive or secretary). The subject of the second sentence was either the pronoun he or she. Reading time was significantly longer when gender of the pronoun mismatched the gender stereotype of the antecedent than when the genders of pronoun and antecedent matched. This gender mismatch effect occurred on the two regions immediately following the region containing the pronoun. The results indicated that word-specific gender stereotypes can influence coreference resolution of pronouns.     

Strengths and Subjective Wellbeing in Adolescence: Strength-Based Parenting and the Moderating Effect of Mindset

Recent research suggests that strength-based parenting—the tendency for parents to see and encourage children to use their strengths—relates to lower stress and higher life satisfaction in adolescents. The current study tests whether strength-based parenting, in conjunction with a teenager’s strengths use, influences the teenager’s subjective wellbeing, and whether a growth mindset moderates the relationship between strength-based parenting and strengths use. Three hundred and sixty three adolescents (M _age = 13.74, 51% female) completed questionnaire measures of strength-based parenting, strengths use, subjective wellbeing (life satisfaction, positive affect, and negative affect), Extraversion, Neuroticism, and two aspects of growth mindset. A hierarchical regression using latent variables found that strengths use and strength-based parenting were both significant independent predictors of subjective wellbeing, over and above the effects of extraversion and neuroticism. A mediation analysis found that strengths use partially mediated the relationship between strength-based parenting and subjective wellbeing. Finally, a novel measure of strengths mindset significantly moderated the relationship between strength-based parenting and strengths use. These results suggest that adolescents who see their parents as strength-based report greater strengths use (especially when they have a growth mindset about their strengths) and greater subjective wellbeing.     

Effects of varying stimulus size on object recognition in pigeons

The authors investigated the pigeon's ability to generalize object discrimination performance to smaller and larger versions of trained objects. In Experiment 1, they taught pigeons with line drawings of multipart objects and later tested the birds with both larger and smaller drawings. The pigeons exhibited significant generalization to new sizes, although they did show systematic performance decrements as the new size deviated from the original. In Experiment 2, the authors tested both linear and exponential size changes of computer-rendered basic shapes to determine which size transformation produced equivalent performance for size increases and decreases. Performance was more consistent with logarithmic than with linear scaling of size. This finding was supported in Experiment 3. Overall, the experiments suggest that the pigeon encodes size as a feature of objects and that the representation of size is most likely logarithmic.     

The Effect of Auditory Cueing on the Spatial and Temporal Gait Coordination in Healthy Adults

Walk ratio, defined as step length divided by cadence, indicates the coordination of gait. During free walking, deviation from the preferential walk ratio may reveal abnormalities of walking patterns. The purpose of this study was to examine the impact of rhythmic auditory cueing (metronome) on the neuromotor control of gait at different walking speeds. Forty adults (mean age 26.6 ± 6.0 years) participated in the study. Gait characteristics were collected using a computerized walkway. In the preferred walking speed, there was no significant difference in walk ratio between uncued (walk ratio = .0064 ± .0007 m/steps/min) and metronome-cued walking (walk ratio = .0064 ± .0007 m/steps/min; p = .791). A higher value of walk ratio at the slower speed was observed with metronome-cued (walk ratio = .0071 ± .0008 m/steps/min) compared to uncued walking (walk ratio = .0068 ± .0007 m/steps/min; p < .001). The walk ratio was less at faster speed with metronome-cued (walk ratio = .0060 ± .0009 m/steps/min) compared to uncued walking (walk ratio = .0062 ± .0009 m/steps/min; p = .005). In healthy adults, the metronome cues may become an attentional demanding task, and thereby disrupt the spatial and temporal integration of gait at nonpreferred speeds.     

Beyond accuracy: Epistemic flaws with statistical generalizations

What, if anything, is epistemically wrong with beliefs involving accurate statistical generalizations about demographic groups? This paper argues that there is a perfectly general, underappreciated epistemic flaw which affects both ethically charged and uncharged statistical generalizations. Though common to both, this flaw can also explain why demographic statistical generalizations give rise to the concerns they do. To identify this flaw, we need to distinguish between the accuracy and the projectability of statistical beliefs. Statistical beliefs are accompanied by an implicit representation of the statistic's modal profile. Their modal profile determines the circumstances in which they can legitimately be projected to unobserved instances. Errors in that implicit content can be compatible with the accuracy of the “bare” statistic, whilst systematically leading to downstream errors in reasoning, in a manner which reveals an epistemic flaw with an important aspect of the belief state itself.     

Past and Future Episodic Thinking in Middle Childhood

The abilities of past and future episodic thinking develop hand in hand across the preschool years and are intimately connected in adults. Little is known, however, about the development of episodic thinking in middle childhood and how it is influenced by sociocultural factors. In the present study, one hundred sixty-seven 7- to 10-year-old children from European American and Chinese cultural backgrounds were interviewed individually about temporally near and distant past and future events. The child data were further contrasted with adult data in Wang, Hou, Tang, and Wiprovnick (2011 Wang , Q. , Hou , Y. , Tang , H. , &; Wiprovnick , A. ( 2011 ). Traveling backward and forward in time: Culture and gender in the episodic specificity of past and future events . Memory , 19 , 103 – 109 . doi: 10.1080/09658211.2010.537279 [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). European American children generated more specific details than did Chinese children in both past and future events. Children of the two cultures relied similarly on general knowledge in their episodic thinking, and yet, they did so to a greater extent when compared with adults. In addition, similar to adults, children exhibited consistency in episodic specificity between past- and future-event construction, and they generated more specific details in past events compared with future events and in near events compared with distant events. The findings provide important insights for the development of episodic thinking in middle childhood and beyond.
