Verbal interference suppresses exact numerical representation

Language for number is an important case study of the relationship between language and cognition because the mechanisms of non-verbal numerical cognition are well-understood. When the Pirahã (an Amazonian hunter-gatherer tribe who have no exact number words) are tested in non-verbal numerical tasks, they are able to perform one-to-one matching tasks but make errors in more difficult tasks. Their pattern of errors suggests that they are using analog magnitude estimation, an evolutionarily- and developmentally-conserved mechanism for estimating quantities. Here we show that English-speaking participants rely on the same mechanisms when verbal number representations are unavailable due to verbal interference. Followup experiments demonstrate that the effects of verbal interference are primarily manifest during encoding of quantity information, and—using a new procedure for matching difficulty of interference tasks for individual participants—that the effects are restricted to verbal interference. These results are consistent with the hypothesis that number words are used online to encode, store, and manipulate numerical information. This linguistic strategy complements, rather than altering or replacing, non-verbal representations.     

Hemispheric asymmetry in cross-race face recognition

This study examines two phenomena related to face perception, both of which depend on experience and holistic processing: perceivers process faces more efficiently in the right hemisphere of the brain (a hemispheric asymmetry), and they typically show greater recognition accuracy for members of their racial ingroup (a cross-race recognition deficit). The current study tests the possibility that these two effects are related. If asymmetry depends on experience, it should be particularly evident with (more familiar) ingroup faces; if cross-race recognition relies on holistic processing, it should be particularly evident for faces presented to the right hemisphere. Black and White participants viewed Black and White faces presented to either the left or right visual field. As predicted, participants showed a more pronounced asymmetry for ingroup (rather than outgroup) faces, and cross-race recognition deficits were more pronounced for stimuli presented to the left (rather than the right) visual field.     

Effect of visual-verbal load and spatial compatibility on stimulus response

This study examined the effects of visual-verbalload (as measured by a visually presented reading-memory task with three levels) on a visual/auditory stimulus-response task. The three levels of load were defined as follows: "No Load" meant no other stimuli were presented concurrently; "Free Load" meant that a letter (A, B, C, or D) appeared at the same time as the visual or auditory stimulus; and "Force Load" was the same as "Free Load," but the participants were also instructed to count how many times the letter A appeared. The stimulus-response task also had three levels: "irrelevant," "compatible," and "incompatible" spatial conditions. These required different key-pressing responses. The visual stimulus was a red ball presented either to the left or to the right of the display screen, and the auditory stimulus was a tone delivered from a position similar to that of the visual stimulus. Participants also processed an irrelevant stimulus. The results indicated that participants perceived auditory stimuli earlier than visual stimuli and reacted faster under stimulus-response compatible conditions. These results held even under a high visual-verbal load. These findings suggest the following guidelines for systems used in driving: an auditory source, appropriately compatible signal and manual-response positions, and a visually simplified background.     

Stereotype threat: Antecedents and consequences for working women

Three studies investigated antecedents and consequences of stereotype threat for female employees. The results of Studies 1 and 2 suggest that social comparisons with men are associated with feelings of stereotype threat whereas social comparisons with women are not. Stereotype threat, in turn, was associated with conflict surrounding women's identity as female employees and with decreased perceived likelihood of achieving career goals. Study 3 extended these findings by demonstrating that feelings of stereotype threat are also negatively related to workplace attitudes and turnover intentions. Furthermore, the effect of stereotype threat on these job attitudes and intentions was itself mediated by identity conflict and perceived likelihood of achieving career goals. Implications and limitations of these findings are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Psychopathic personality as a distinctive indicator of severity and persistence for child and youth conduct problems

Conduct problems are among the most discussed behavioral problems during childhood and adolescence. Given their heterogeneity, in recent years, researchers on this topic have called for delineation of early-onset conduct problems on the basis of affective, interpersonal and behavioral traits that resemble adult psychopathy. The present study aims to analyze, from both a cross-sectional and longitudinal perspective, whether early psychopathic traits allow identification of a group of individuals defined by severe and persistent behavioral problems. To achieve this goal, data from a sample of 192 children (aged 6 to 11) were analyzed; from this sample, 133 children were followed-up in a new data collection that took place three years later. From the data obtained with the mCPS and CBCL (parents), and APSD and TRF (teachers), we observed that children who showed early psychopathic traits, also showed greater frequency, severity and persistence of conduct problems. These results suggest the need to take into account the role of psychopathic traits (particularly, affective and interpersonal) as risk factors to delimit the most serious and persistent patterns of externalizing behavior.     

EFFECTS OF VIDEO MODELING ON TEACHING BIDS FOR JOINT ATTENTION TO CHILDREN WITH AUTISM

The purpose of this study was to evaluate the effects of video modeling to teach children with autism to initiate bids for joint attention. The video model consisted of a child demonstrating three components of a bid for joint attention with an adult conversational partner: orienting toward the object, emitting a vocal statement, and eye gaze shift toward unique objects in the environment. Results indicated that video modeling alone was effective in teaching all components of joint attention for two of the three children, whereas video modeling plus in vivo prompting was effective for the third participant. Further, bids for joint attention did not generalize across novel items for any of the participants. Results are discussed in terms of the social relevance and validity of the use of video modeling to teach a complex social behavior such as bids for joint attention.

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.

     

Positive and extensive intergroup contact in the past buffers against the disproportionate impact of negative contact in the present

Negative (vs positive) intergroup contact may have a disproportionately large impact on intergroup relations because of valence‐salience effects, whereby negative contact causes higher category salience (Paolini, Harwood, & Rubin, 2010). One correlational and three experimental studies in three conflict areas (Northern Ireland, Arizona's border area, and Cyprus; Ns = 405, 83, 76, and 91) tested the moderation of these valence‐salience effects by individuals' histories of outgroup contact. Consistent with a perceived fit principle valence‐salience effects of face‐to‐face, television‐mediated, and imagined contact held among individuals with negative or limited histories of outgroup contact; these effects were significantly reduced or nonsignificant among individuals with positive or extensive past outgroup contact. These moderation effects suggest that positive and diverse intergroup contact in the past buffers against the harmful effects of negative contact experiences in the present, thus limiting the potential for negative spiralling of intergroup relations.

Dimensions of Oppositional Defiant Disorder in Young Children: Heterotypic Continuity with Anxiety and Depression

There are distinct dimensions of Oppositional Defiant Disorder (ODD) that have been associated with symptoms of other disorders (heterotypic continuity). The present study compared the heterotypic continuity of a two-factor (Pitt-2) model and the three-factor model incorporated into DSM-5 with symptoms of anxiety and depression. Participants were a diverse community sample of 796 children (38.8 % minority, 49.1 % boys) assessed at ages 4, 5 and 6 years. Symptoms were assessed with the dimensional scales of the Diagnostic Interview Schedule for Children-Young Child version and the Child Symptom Inventory. Dimensions of both the two- and three-factor DSM-5 models were associated with later symptoms of anxiety and depression. The association, however, was weak when accounting for initial levels of internalizing symptoms: thus there was little evidence for the unique contributions of ODD dimensions to symptoms of subsequent internalizing disorders for either model.
