It Takes Two to Tangle: Gender Symmetry in Intimate Partner Violence

This study examined the equivalence of male and female intimate partner violence (IPV) across three samples of the New Zealand population (student, general, and incarcerated). Additionally, we compared the attitudes of victims and perpetrators. Findings revealed that although the incarcerated sample experienced a higher frequency of violence, the nature of IPV was similar across the samples. More importantly, our findings showed gender symmetry in IPV with male and female IPV being similar in frequency, severity, and injury. There was, however, some variation in the type of physical abuse acts perpetrated as a function of gender. Furthermore, victims and perpetrators reported similar attitudes and behaviors that differentiated them from participants with no history of physical violence. These included being more hostile, holding traditional gendered beliefs, and lacking communication and anger management skills. A rethinking of how we view IPV is recommended in light of these findings.     

Predicting Immigrants' Attitudes Toward Multiculturalism Using a Measure of Its Perceived Benefits

We examined the predictors of attitudes toward multiculturalism in a sample of Asian and African immigrants. Multiculturalism was measured in terms of its perceived benefits as realized through Canadian government policy. As well as replicating past findings, two hypotheses derived from social identity theory are supported: Canadian identity and acculturation into Canadian society were significant predictors of attitudes toward multiculturalism. Counter to previous research findings, perceived discrimination was a negative predictor of these attitudes. The distinction between predicting support for attitudes toward multiculturalism measured as an ideology versus attitudes toward multiculturalism measured in terms of its perceived benefits is discussed.     

Rapid changes in visual-spatial attention distort object shape

Shifts of attention due to rapid cue onsets have been shown to distort the perceived location of objects, but are there also systematic distortions in the perceived shapes of the objects themselves from such shifts? The present study demonstrates that there are. In three experiments, oval contours were presented that varied in width and height. Two brief, bright white dots were presented as cues and were positioned horizontally or vertically either inside or outside the oval contour. Observers had to judge whether the oval was taller than wide. The results show that the perceived shape of an oval was changed by visual cues such that the oval contours were repelled by the cues (Exp. 1). This effect only occurred when the cues preceded the ovals, providing sufficient time between the presentations to attract involuntary attention (Exp. 2). Moreover, an explanation based on figural aftereffects was ruled out (Exp. 3).     

When here becomes there: attentional distribution modulates foveal bias in peripheral localization

Much research concerning attention has focused on changes in the perceptual qualities of objects while attentional states were varied. Here, we address a complementary question--namely, how perceived location can be altered by the distribution of sustained attention over the visual field. We also present a new way to assess the effects of distributing spatial attention across the visual field. We measured magnitude judgments relative to an aperture edge to test perceived location across a large range of eccentricities (30°), and manipulated spatial uncertainty in target locations to examine perceived location under three different distributions of spatial attention. Across three experiments, the results showed that changing the distribution of sustained attention significantly alters known foveal biases in peripheral localization.     

A hit-and-miss investigation of asymmetries in wheelchair navigation

In contrast to the leftward inattention caused by right parietal damage, normal brain function shows a subtle neglect of the right and left sides in peripersonal and extrapersonal space, respectively. This study explored how these attentional biases cause healthy individuals to collide with objects on the right. In Experiment 1, participants navigated manual and electric wheelchairs through a narrow doorway. More rightward collisions were observed for the electric, but not the manual, wheelchair. Experiment 2 demonstrated that the rightward deviation for electric wheelchairs increased for wider doorways. Experiment 3 established that the rightward deviation is not the result of task-related vestibular input, using a remote control device to operate the wheelchair. The rightward deviation persisted in Experiment 4 when the doorway was removed, suggesting that the bias is the result of a mis-bisection of space. In Experiment 5, the rightward bias was replicated using an electric scooter, which is steered using handlebars. Finally, Experiment 6 required participants to point to the middle of the doorway, using a laser, before moving the scooter. Rightward mis-bisection was observed in both conditions. Rightward mis-bisection of lines in extrapersonal space provides the most parsimonious explanation of the rightward collisions and deviations.     

Social Dominance Orientation and Right-Wing Authoritarianism: Additive and Interactive Effects

The additive and interactive effects of Social Dominance Orientation (SDO) and Right-Wing Authoritarianism (RWA) were examined using 16 independent samples of New Zealand European participants ( N =  2,164). Consistent with Duckitt's (2001) Dual Process Model, SDO and RWA displayed strong additive effects across various domains of intergroup-related attitude, including measures of racism, sexism, homosexual prejudice, and ethnic and religious ingroup identification. In each of these five domains, meta-analysis indicated that the statistical interaction of SDO and RWA accounted for an average of less than .001% variance in addition to their linear combination. It is concluded that the association between SDO and various discriminatory attitudes and beliefs is only extremely weakly dependent on RWA, and vice-versa, suggesting that these two ideological attitudes are primarily additive, rather than interactive, in nature.     

Consolidation,wider reflection,and policy: Response to ‘Super‐recognisers: From the lab to the world and back again’

Here, David Robertson and Markus Bindemann respond to a recent BJP Target Article on ‘super‐recognisers’ (SRs). They outline the need to consider human factors that could influence SR performance after selection and the need for a co‐ordinated effort to ensure best practice in the implementation of SRs in applied contexts.     

Functional projection: how fundamental social motives can bias interpersonal perception

Results from 2 experimental studies suggest that self-protection and mate-search goals lead to the perception of functionally relevant emotional expressions in goal-relevant social targets. Activating a self-protection goal led participants to perceive greater anger in Black male faces (Study 1) and Arab faces (Study 2), both out-groups heuristically associated with physical threat. In Study 2, participants' level of implicit Arab-threat associations moderated this bias. Activating a mate-search goal led male, but not female, participants to perceive more sexual arousal in attractive opposite-sex targets (Study 1). Activating these goals did not influence perceptions of goal-irrelevant targets. Additionally, participants with chronic self-protective and mate-search goals exhibited similar biases. Findings are consistent with a functionalist, motivation-based account of interpersonal perception.     

Action control: independent effects of memory and monocular viewing on reaching accuracy

Evidence suggests that perceptual networks in the ventral visual pathway are necessary for action control when targets are viewed with only one eye, or when the target must be stored in memory. We tested whether memory-linked (i.e., open-loop versus memory-guided actions) and monocular-linked effects (i.e., binocular versus monocular actions) on action arise from a common mechanism as suggested by evidence from neuropsychology and psychophysics. Participants viewed targets with either one eye or two (vision: monocular versus binocular) and then reached to touch targets in open-loop and memory-guided conditions (condition: open-loop versus 0, 500, 1000, and 1500 ms delays). Results showed that memory-linked and monocular-linked increases in radial and variable movement error were additive (i.e., main effects of vision and condition, but no interaction). This suggests that the two effects on visuomotor control arise from separate mechanisms, in contrast to evidence from psychophysics and neuropsychology suggesting a common underlying mechanism.
