True, justified, belief? Partisanship weakens the positive effect of news media literacy on fake news detection

To investigate how people assess whether politically consistent news is real or fake, two studies (N = 1,008; N = 1,397) with adult American participants conducted in 2020 and 2022 utilized a within-subjects experimental design to investigate perceptions of news accuracy. When a mock Facebook post with either fake (Study 1) or real (Study 2) news content was attributed to an alternative (vs. a mainstream) news outlet, it was, on average, perceived to be less accurate. Those with beliefs reflecting News Media Literacy demonstrated greater sensitivity to the outlet’s status. This relationship was itself contingent on the strength of the participant’s partisan identity. Strong partisans high in News Media Literacy defended the accuracy of politically consistent content, even while recognizing that an outlet was unfamiliar. These results highlight the fundamental importance of looking at the interaction between user-traits and features of social media news posts when examining learning from political news on social media

Exposure to Conflict and Violence across Contexts: Relations to Adjustment among Palestinian Children

Despite extensive literatures on the impact on children of exposure to violence in families, neighborhoods, and peer groups, there has been relatively little effort evaluating their cumulative impact. There also has been less attention to the effects of exposure to political conflict and violence. We collected data from a representative sample of 600 Palestinian youths (3 age cohorts: 8, 11, and 14 years old) to evaluate the relation of exposure to political conflict and violence, and violence in the family, community, and school, to posttraumatic stress (PTS) symptoms and aggressive behavior. Results highlight the additive effects of exposure to political conflict and violence, suggesting that interventionists should consider the full spectrum of sources of environmental risk for PTS symptoms and aggressive behavior.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/83446/1/2010.DubowEtAl.ExposureToConflict.JCCAP.pd

Learning the hard way: the effect of violent conflict on student academic achievement

We study the effect of the Israeli–Palestinian conflict on various education outcomes for Palestinian high school students in the West Bank during the Second Intifada (2000–2006). Exploiting within-school variation in the number of conflict-related Palestinian fatalities during the academic year, we show that the conflict reduces the probability of passing the final exam, the total test score, and the probability of being admitted to university. The effect of conflict varies with the type and the timing of the violent events the student is exposed to and it is not significant for students in the upper tail of the test score distribution. We discuss various possible transmission mechanisms explaining our main result. Evidence suggests a role for both the conflict-induced deterioration of school infrastructures and the worsening in the student's psychological well-being due to direct exposure to violent events

Dynamics and stability of directional jumps in the desert locust

Locusts are known for their ability to jump large distances to avoid predation. The jump also serves to launch the adult locust into the air in order to initiate flight. Various aspects of this important behavior have been studied extensively, from muscle physiology and biomechanics, to the energy storage systems involved in powering the jump, and more. Less well understood are the mechanisms participating in control of the jump trajectory. Here we utilise video monitoring and careful analysis of experimental directional jumps by adult desert locusts, together with dynamic computer simulation, in order to understand how the locusts control the direction and elevation of the jump, the residual angular velocities resulting from the jump and the timing of flapping-flight initiation. Our study confirms and expands early findings regarding the instrumental role of the initial body position and orientation. Both real-jump video analysis and simulations based on our expanded dynamical model demonstrate that the initial body coordinates of position (relative to the hind-legs ground-contact points) are dominant in predicting the jumps’ azimuth and elevation angles. We also report a strong linear correlation between the jumps’ pitch-angular-velocity and flight initiation timing, such that head downwards rotations lead to earlier wing opening. In addition to offering important insights into the bio-mechanical principles of locust jumping and flight initiation, the findings from this study will be used in designing future prototypes of a bio-inspired miniature jumping robot that will be employed in animal behaviour studies and environmental monitoring applications

The spoiler effect: Framing attitudes and expectations toward peace

This study analyzes the impact of media framing on aggregate attitudes and expectations of Israelis toward the Oslo peace process with the Palestinians during a time period of eight years (1995-2003). It presents three main contributions: First, it provides a long-term analysis of the impact of media coverage of a peace process on public opinion, while controlling for the influence of real life events. Second, it presents empirical evidence that the strength of media framing effects varies among different facets of public opinion. Specifically, framing effects are stronger on aggregate future expectations compared with their effects on aggregate current attitudes. The fact that the information transmitted by the media evaluative tone was a central source of influence on future expectations underlines the central role of the media in political and social phenomena. Third, in line with previous studies, it shows that the public response to negative framing is much stronger than to positive framing. This may have a negative effect on a government's ability to rally the public in support of a peace process. Since most media coverage of the peace process and conflict focused on negative developments while ignoring positive ones, the media effect on public opinion was that of peace spoilers.framing effects, Israel, media and peace, media framing, negativity bias, Palestine, public expectations

"You're still worth it": The moral and relational context of politically motivated unfriending decisions in online networks.

Political disagreements in social media can result in removing (i.e., "unfriending") a person from one's online network. Given that such actions could lead to the (ideological) homogenization of networks, it is pivotal to understand the psychological processes intertwined in unfriending decisions. This requires not only addressing different types of disagreements but also analyzing them in the relational context they occur. This article proposes that political disagreements leading to drastic measures such as unfriending are attributable to more deeply rooted moral dissents. Based on moral foundations theory and relationship regulation research, this work presents empirical evidence from two experiments. In both studies, subjects rated political statements (that violated different moral foundations) with regard to perceived reprehensibility and the likelihood of unfriending the source. Study 1 (N = 721) revealed that moral judgments of a political statement are moderately related to the unfriending decision. Study 2 (N = 822) replicated this finding but indicated that unfriending is less likely when the source of the morally reprehensible statement is relationally close to the unfriender and provides emotional support. This research extends unfriending literature by pointing to morality as a new dimension of analysis and offers initial evidence uncovering the psychological trade-off behind the decision of terminating digital ties. Drawing on this, our findings inform research on the homogenization of online networks by indicating that selective avoidance (in the form of politically motivated unfriending) is conditional upon the relational context and the interpersonal benefits individuals receive therein
