Implicit response-irrelevant number information triggers the SNARC effect: Evidence using a neural overlap paradigm

There is evidence from the SNARC (spatial–numerical association of response codes) effect and NDE (numerical distance effect) that number activates spatial representations. Most of this evidence comes from tasks with explicit reference to number, whether through presentation of Arabic digits (SNARC) or through magnitude decisions to nonsymbolic representations (NDE). Here, we report four studies that use the neural overlap paradigm developed by Fias, Lauwereyns, and Lammertyn (2001) to examine whether the presentation of implicit and task-irrelevant numerosity information (nonsymbolic arrays and auditory numbers) is enough to activate a spatial representation of number. Participants were presented with either numerosity arrays (1–9 circles or triangles) to which they made colour (Experiment 1) or orientation (Experiment 2) judgements, or auditory numbers coupled with an on-screen stimulus to which they made a colour (Experiment 3) or orientation (Experiment 4) judgement. SNARC effects were observed only for the orientation tasks. Following the logic of Fias et al., we argue that this SNARC effect occurs as a result of overlap in parietal processing for number and orientation judgements irrespective of modality. Furthermore, we found stronger SNARC effects in the small number range (1–4) than in the larger number range (6–9) for both nonsymbolic displays and auditory numbers. These results suggest that quantity is extracted (and interferes with responses in the orientation task) but this is not exact for the entire number range. We discuss a number of alternative models and mechanisms of numerical processing that may account for such effects.     

Cooperation in Mixed‐Motive Games: The Role of Individual Differences in Selfish and Social Orientation

In mixed‐motive games, people must choose between acting upon selfish interests and concerns for others. Yet, the consistency of people's behaviour across these various games is still unclear. If the same conflict between self and others is at the core of all mixed‐motive situations, three hypotheses can be stated: (1) behaviours in different mixed‐motive games should be substantially related; (2) all these games should substantially appeal to dispositional variables that probe in the psychological conflict between self and others; and (3) these dispositional variables should explain the shared variance among various games. These hypotheses were tested among undergraduate students (N = 219) who played seven different single‐shot mixed‐motive games and one sequential game. Social Value Orientation and the ideological attitudes Social Dominance Orientation and Right‐Wing Authoritarianism were included as dispositions. Our findings, however, showed evidence that did not fully substantiate our hypotheses, which calls into question the general idea that all mixed‐motive games render the conflict between selfish interests and concern for others salient. In the discussion, we focus on implications for research on mixed‐motive situations and elaborate on the role of ideology in this domain.

Cultural and Institutional Determinants of Social Dominance Orientation: A Cross‐Cultural Meta‐Analysis of 27 Societies

We investigate macrocontextual antecedents of national levels of Social Dominance Orientation (SDO). The majority of previous research, in contrast, has tended to focus on individual‐level correlates of SDO. We extend research on Social Dominance Theory by modelling national‐level differences in institutional discrimination, macroeconomic development, and value ideologies as broad situational factors affecting SDO mean levels in previous studies. Our hypotheses were tested in a three‐level meta‐analysis of aggregate data from 50,971 individuals in 95 samples from 27 different societies. Strong effects for hierarchy‐attenuating legitimizing ideologies and gender empowerment were found. Aggregate discrimination against arbitrary‐set groups was less consistently linked to SDO, suggesting that these hierarchies are context‐specific. Using mixed‐effects three‐level modelling, the patterns can be generalized to new contexts and suggest a particular institutional and social climate that fosters high SDO.     

The political glass cliff: When left-wing orientation leads to minority candidate choices for hard-to-win seats

IntroductionGlass cliff evidence shows that women and ethnic, racial, and immigration (ERI) groups are more likely to face precarious leadership positions than majority groups. In politics, this is illustrated by minority candidates running for harder-to-win seats than majority candidates.ObjectiveThe present research extends these correlational findings on ERI populations to an experimental setting and investigates the underlying reasons.MethodTwo scenario-based experimental studies were conducted with voting populations in France and Switzerland, who took the role of party decision-maker. In Study 1 (n = 64), we manipulated candidate origin and measured the choice of political ward (hard vs. easy-to-win), while in Study 2 (n = 151), we manipulated ward winnability and measured candidate choice (ERI minority vs. majority).ResultsOverall, findings suggest that ERI minority (compared to majority) political candidates were more likely to be matched with hard-to-win than easy-to-win political wards. Of interest, this finding only occurred for participants with a political left-wing orientation. Moreover, both studies investigated the reasons underlying such tendency and, in particular, focused on participants’ motivation to implement change.ConclusionThe discussion confronts hostile and benign motives for glass cliff decisions and highlights the potentially distinct consequences for minority candidates.     

Influence of teachers’ political orientation and values on their success prediction toward students from different socioeconomic background

IntroductionTeachers tend to develop negative expectations and behaviours towards students coming from low socioeconomic backgrounds.ObjectiveThe objective of this study was to test the influence of teacher political orientation, as well as their attachment to power and universalism values, on their predictions of academic success towards students from different socioeconomic backgrounds.MethodEighty-eight high school teachers (M_age = 38.04 years; 44.3% men) responded to a questionnaire of political ideology and values, as well as to a questionnaire evaluating their prediction of success towards male high school students from different socioeconomic backgrounds.ResultsTeachers predicted a better academic success for students coming from a high socioeconomic background. Despite relatively small effect size, political ideology, as well as attachment to power and universalism values, predicted the bias of judgment.ConclusionTaking into consideration teachers’ ideology and values would deepen understanding of processes underlying expectations development.     

Cognitive profile of patients with rotated drawing at copy or recall: A controlled group study

When copying or recalling a figure from memory, some patient with dementia or focal brain lesions may rotate the drawing through ±90° or 180°. We have tried to clarify the nature of this phenomenon by investigating the cognitive profile of 22 patients who rotated the copy of the Rey–Osterrieth Complex Figure and 27 who rotated (only) the recall, and two control groups of cases with the same neuropsychiatric diagnoses, but no misorientation deficit. Brain MRI and FDG-PET images were also analysed. Predictor of rotation at the copy versus rotation at the recall was visuospatial impairment as measured by the copy of the Rey Figure; predictors of rotation at the copy versus no rotation were, again, visuospatial deficits, in addition to an abnormal performance at the task of selective attention. No specific profile of cognitive impairment distinguished patients with and without rotation at the recall. Disproportionate temporo-parieto-occipital atrophy or hypometabolism were evident in cases with misorientation of the copy, while predominant frontal abnormalities were found in cases of rotated recall. Based on these findings, rotated drawing at the copy is interpreted as a dorsal visual stream deficit, whose occurrence is more probable when attentional control is impaired. Rotation at recall seems to have a distinct, more anterior, neural substrate, but its dysexecutive nature has yet to be demonstrated.
