Defective number module or impaired access? Numerical magnitude processing in first graders with mathematical difficulties

This study examined numerical magnitude processing in first graders with severe and mild forms of mathematical difficulties, children with mathematics learning disabilities (MLD) and children with low achievement (LA) in mathematics, respectively. In total, 20 children with MLD, 21 children with LA, and 41 regular achievers completed a numerical magnitude comparison task and an approximate addition task, which were presented in a symbolic and a nonsymbolic (dot arrays) format. Children with MLD and LA were impaired on tasks that involved the access of numerical magnitude information from symbolic representations, with the LA children showing a less severe performance pattern than children with MLD. They showed no deficits in accessing magnitude from underlying nonsymbolic magnitude representations. Our findings indicate that this performance pattern occurs in children from first grade onward and generalizes beyond numerical magnitude comparison tasks. These findings shed light on the types of intervention that may help children who struggle with learning mathematics.     

The weight of time: affordances for an integrated magnitude system

In five experiments we explored the effects of weight on time in different action contexts to test the hypothesis that an integrated magnitude system is tuned to affordances. Larger magnitudes generally seem longer; however, Lu and colleagues (2009) found that if numbers were presented as weights in a range heavy enough to affect lifting, the "larger seems longer" effect was enhanced, but it was eliminated with weights too light to affect lifting. Experiments 1 and 2 revealed that actually lifting kilogram and gram weights had effects parallel to symbolized weights, suggesting that Lu et al.'s task implicitly evoked a lifting context. Experiments 3 and 4 showed that weights too heavy (e.g., tons) or too light to be discriminated by lifting, but relevant to other affordances (e.g., grams of a toxin) had effects on time as large or larger than for kilograms. Experiment 5 showed that the effect for grams in a toxicology context did not generalize to the lifting task of Experiment 2. Weight appears to integrate with other magnitudes when it is relevant to meaningful actions, including but not limited to lifting.     

Attitude similarity and familiarity and their links to mental health: An examination of potential interpersonal mediators

Similarity and familiarity with partner’s attitudes are linked to positive relationship outcomes, while interpersonal variables have been linked to mental health. Using multilevel models (MLMs), we modeled the associations between these attitudinal variables and mental health outcomes in 74 married couples. We found that higher levels of attitude similarity in couples were linked to lower depression, while higher levels of attitude familiarity in couples were associated with greater satisfaction with life. Mediational analyses indicated marital satisfaction and interpersonal stress mediated the link between attitude similarity and depression. Marital satisfaction also mediated the link between familiarity and satisfaction with life. This study is the first linking attitude familiarity to mental health and provides evidence that familiarity and similarity have mental health effects partly due to their interpersonal consequences.     

The Relation between Selection Expectations,Perceptions and Organizational Attraction: A test of competing models

Little is known about how applicants' selection expectations and perceptions interplay in predicting applicant attraction outcomes (organizational attractiveness, job pursuit intention, and recommendation intention). In the present study, 340 entry‐level applicants for jobs in a large financial company provided information about their selection expectations before the procedure, and about their perceptions and attraction to the organization after the procedure. Regression analyses indicated that applicant perceptions, and in particular perceptions of warmth/respect, mediated the relationship between selection expectations and organizational attractiveness and job pursuit intention. No support was found for the moderating role of selection expectations in the perception–attraction relationship. Implications for practice and future research are discussed.     

Ingratiation and Self‐Promotion in the Selection Interview: The Effects of Using Single Tactics or a Combination of Tactics on Interviewer Judgments

This paper investigates the relative effectiveness of the use of 2 impression‐management tactics—ingratiation and self‐promotion—on interviewers' evaluations of an applicant in a laboratory setting. It was suggested that the use of a single tactic would be better than the use of no tactic; that the use of self‐promotion would be more successful than the use of ingratiation; and, finally, that the use of a combination of tactics would lead to the best evaluations. Results were largely in line with our hypotheses. Interviewer ratings and action recommendations were more positive in the combination condition, followed by the self‐promotion condition, the ingratiation condition, and the neutral condition. Theoretical and practical implications are discussed.

Multimedia learning trumps retrieval practice in psychology teaching

It is well established that studying with (vs. without) visual illustrations as well as taking tests (vs. restudying) is beneficial for learning, but on which strategy should one put the efforts, or should they be combined for best learning? Eighty‐eight upper secondary school students were given a brief lecture presented verbally (6 classes) or with the aid of a visual illustration (visuoverbal, 6 classes). The information was processed again by taking a memory test or by restudying. Recall and transfer tests were conducted after some few minutes and again after one week. The visuoverbal lecture resulted in better learning than verbal presentation only. A significant study strategy by retention interval interaction was found. However, this interaction was not qualified by a testing effect. Hence, taking tests (retrieval practice) did not lead to better learning than restudying. It was concluded that it is worthwhile to use visual illustrations in teaching. However, the present study did not reveal any synergistic effects from the combination of visuoverbal presentation and retrieval practice.     

Redeeming Apartheid's Legacy: Collective Guilt, Political Ideology, and Compensation

This paper reports two studies among white South African students on feelings of collective guilt about apartheid and attitudes to affirmative action. Study 1 reports on 21 in-depth interviews, Study 2 on results from 180 survey questionnaires. Substantial proportions of the participants in both studies displayed feelings of collective guilt. Among participants in both studies who identified strongly with white South Africans, some displayed strong feelings of collective guilt while others displayed no such feelings. Our survey data suggest that political ideology functions as a moderator. Strong feelings of guilt were found among students who identified strongly with white South Africans and defined themselves as liberals. If they defined themselves as conservatives then no feelings of collective guilt were observed. Strong feelings of collective guilt were accompanied by positive attitudes toward affirmative action. The influence of political ideology on attitudes toward affirmative action was mediated by collective guilt.
