Integration of visual information for saccade production

To foveate a visual target, subjects usually execute a primary hypometric saccade (S1) bringing the target in perifoveal vision, followed by a corrective saccade (S2) or by more than one S2. It is still debated to what extent these S2 are pre-programmed or dependent only on post-saccadic retinal error. To answer this question, we used a visually-triggered saccade task in which target position and target visibility were manipulated. In one-third of the trials, the target was slightly displaced at S1 onset (so-called double step paradigm) and was maintained until the end of S1, until the start of the first S2 or until the end of the trial. Experiments took place in two visual environments: in the dark and in a dimly lit room with a visible random square background. The results showed that S2 were less accurate for shortest target durations. The duration of post-saccadic visual integration thus appears as the main factor responsible for corrective saccade accuracy. We also found that the visual context modulates primary saccade accuracy, especially for the most hypometric subjects. These findings suggest that the saccadic system is sensitive to the visual properties of the environment and uses different strategies to maintain final gaze accuracy.     

Aligning inside and outside perspectives of the self: A cross‐cultural difference in self‐perception

Past research shows that European Americans tend to take a first‐person perspective to understand the self and are unlikely to align the inside look with the outside gaze, whereas Asians tend to take a third‐person perspective and are likely to shift their inside look in the direction of the outsize gaze. In three experiments, we compared Asians and European Americans' self‐perceptions when the presence of their parents in the background of self‐perception was primed or otherwise. Without the priming, both European Americans and Asians viewed themselves more positively from their own perspective than from their parents' perspective. With the priming, only Asians lowered the positivity of their self‐perceptions to match the perceived positivity of the self in the parents' perspective. These results suggest that Asians do not have a static, passive tendency to assimilate their self‐views into the perceived external assessments of the self. Rather, their self‐views are fluid and flexible.

Purity matters more than harm in moral judgments of suicide: Response to Gray (2014)

Many people judge suicide to be immoral. We have found evidence that these moral judgments are primarily predicted by people’s belief that suicide taints the soul and by independent concerns about purity. This finding is inconsistent with accounts that define morality as fundamentally based upon harm considerations. In this commentary, we respond to a critique of our finding, and we provide further support for our original conclusions. Even when applying new exclusion criteria to our data, an examination of effect sizes demonstrates that concerns about purity robustly and meaningfully explain variance in moral judgments of suicide. While harm concerns sometimes predict moral judgments of suicide alongside purity concerns, they reliably explain a much smaller proportion of the variance than do purity concerns. Therefore, data from six studies continue to suggest that the relevance of harm concerns for moral judgments of suicide is substantially overshadowed by the contribution of purity concerns.     

A Bifactor Model of Anxiety Sensitivity: Analysis of the Anxiety Sensitivity Index-3

The purpose of the current study was to investigate the fit of a bifactor model of the Anxiety Sensitivity Index-3 (ASI-3; Taylor et al. Psychological Assessment, 19, 176–188, 2007) as well as to examine measurement invariance of the ASI-3 across gender. Participants were undergraduate students from the University of Cincinnati (n?=?954; 63 % female). Results indicated that the bifactor model was the best fit to the data, and that this model of AS is fully invariant in terms of gender. The current findings suggest that anxiety sensitivity consists of a general factor and three independent group factors (rather than a higher-order factor with three correlated lower-order factors). The ASI-3 subscales from the bifactor model however did not provide incremental predictive utility above and beyond the general AS factor with respect to an external anxiety criterion. Related research and clinical implications are discussed.
