Comfortably Numb: Desensitizing Effects of Violent Media on Helping Others

ABSTRACT— Two studies tested the hypothesis that exposure to violent media reduces aid offered to people in pain. In Study 1, participants played a violent or nonviolent video game for 20 min. After game play, while completing a lengthy questionnaire, they heard a loud fight, in which one person was injured, outside the lab. Participants who played violent games took longer to help the injured victim, rated the fight as less serious, and were less likely to "hear" the fight in comparison to participants who played nonviolent games. In Study 2, violent- and nonviolent-movie attendees witnessed a young woman with an injured ankle struggle to pick up her crutches outside the theater either before or after the movie. Participants who had just watched a violent movie took longer to help than participants in the other three conditions. The findings from both studies suggest that violent media make people numb to the pain and suffering of others.     

Shoemaker on Phenomenal Content

Sydney Shoemaker has given a sophisticated theory of phenomenal content, motivated by the transparency of experience and by the possibility of spectrum inversion without illusion (1994, 2000, 2001, 2002). It centers on the idea that color experiences represent what he calls “appearance properties”. I consider the different sorts of appearance properties that Shoemaker has suggested might enter into phenomenal content – occurrent appearance properties, dispositional appearance properties, and higher-order dispositional appearance properties – and argue that none of them are plausibly represented by color experiences. I argue that Shoemaker's theory faces a dilemma – either it makes misperception too difficult, or it does not truly accommodate veridical spectrum inversion. I then examine some alternative Russellian theories of phenomenal content that might be consistent with Shoemaker's motivations, including a different sort of proposal recently suggested by Shoemaker (forthcoming). I argue that these views are also lacking, for similar reasons as the appearance property view. Finally, I conclude that in order for a representationalist theory to properly accommodate spectrum inversion without illusion, phenomenal content must include an indexical element. Such a view requires the adoption of a broadly Fregean theory of phenomenal content, according to which sameness of phenomenal character does not entail sameness in extension. What phenomenally identical experiences have in common is not what they represent, but how they represent.     

Kuhnian Revolutions Revisited

I re-examine Kuhn’s account of scientific revolutions. I argue that the sorts of events Kuhn regards as scientific revolutions are a diverse lot, differing in significant ways. But, I also argue that Kuhn does provide us with a principled way to distinguish revolutionary changes from non-revolutionary changes in science. Scientific revolutions are those changes in science that (1) involve taxonomic changes, (2) are precipitated by disappointment with existing practices, and (3) cannot be resolved by appealing to shared standards. I argue that an important and often overlooked dimension of the Kuhnian account of scientific change is the shift in focus from theories to research communities. Failing to make this shift in perspective might lead one to think that when individual scientists change theories a scientific revolution has occurred. But, according to Kuhn, it is research communities that undergo revolutionary changes, not individual scientists. I show that the change in early modern astronomy is aptly characterized as a Kuhnian revolution.     

Interindividual‐intergroup discontinuity as a joint function of acting as a group and interacting with a group

An experiment assessed the prisoner's dilemma game (PDG) choices of a set of three persons who interacted with another supposed set of three persons. There were four conditions: (1) group‐on‐group (both three‐person sets constrained by a majority vote), (2) group‐on‐one (only own three‐person set constrained by a majority vote), (3) one‐on‐group (only other three‐person set constrained by a majority vote), (4) one‐on‐one (neither three‐person set constrained by a majority vote). The four conditions were compared with three orthogonal contrasts. Consistent with the assumption that interindividual interactions are less competitive than interactions involving groups, the first contrast indicated that there were fewer competitive choices in the one‐on‐one condition than in the other three conditions pooled. Consistent with the assumption that competitiveness can flow either from acting as a group or interacting with a group, the second contrast found no significant difference between the group‐on‐one and one‐on‐group conditions. Finally, consistent with the assumption that the interindividual‐intergroup discontinuity effect is a joint function of acting as a group and interacting with a group, the third contrast revealed that there were more competitive choices in the group‐on‐group condition than in the one‐on‐group and group‐on‐one conditions pooled.

Improving session attendance in mental health and substance abuse settings: a review of controlled studies

Patient nonattendance to scheduled sessions results in excessive costs to mental health and substance abuse providers and compromises the care of clients. This paper presents a comprehensive review of interventions that have been shown to increase session attendance rates in these settings. Unique to other review papers, reliability estimates were performed in the selection and evaluation of obtained studies. Reliability of article selection and evaluation strategies was excellent (.80 to .88). Study results indicate several attendance improvement methods appear to be particularly promising, such as scheduling appointments promptly, reminder letters and telephone calls, soliciting patient commitment, and helping to resolve obstacles to attending the session. The specific manner in which these interventions are implemented appears to influence session attendance rates. Moreover, some attendance improvement interventions are clearly effective in some settings, but not others. Specific recommendations are provided in light of the study findings.     

Distinguishing Hypotheses From Hyperbole in Studies of Media Violence: A Comment on Markey et al. (2015)

In alleging that Bushman et al. (2013) made sensational and unsubstantiated claims, Markey et al. (2015) mistake hypotheses for hyperbole. Moreover, in their effort to show that gun violence in PG‐13 movies (for ages 13 and older) is unrelated to trends in population violence, they make unjustified demands on our data, with outcomes that are unconnected to hypothesized effects. Using outcomes in line with our hypotheses, we draw the contrary conclusion that recent trends in gun violence in youth are actually consistent with gun violence trends in PG‐13 movies. Nevertheless, because we do not believe those patterns are sufficient to draw causal conclusions, we suggest more adequate tests of the hypothesis that exposure to movie gun violence affects the beliefs and attitudes of youth toward guns.     

Part‐set cueing effects in a diagnostic setting with professional auditors

The aim of this research is to examine the generality of the part‐set cueing effect, a well‐known memory‐inhibition phenomenon in basic research, to professional problem diagnosis. Three experiments were conducted. Experiment 1 examines whether part‐set cueing affects the ability of auditors to recall diagnoses, and if so, whether memory inhibition is affected by the plausibility of the hypotheses. Experiment 2 examines whether the part‐set cueing effect is sensitive to changes in the symptoms that drive the diagnosis and whether differences in inhibition occur because of prompt plausibility or because of target plausibility. Experiment 3 extends the findings of the first two experiments to hypothesis generation and discriminates between competing accounts for the part‐set cueing effect. The results show that part‐set cueing effects occur during hypothesis generation and that they are robust to changes in the symptoms. However, the results from the experiments reveal an asymmetric inhibition effect. Inhibition is significant when prompts contain low plausibility hypotheses that are also high in severity. When prompts consist of high plausibility or low severity hypotheses, no inhibition is observed. These findings are considered to be consistent with an editing account of the part‐set cueing phenomenon. The implications of these findings to problem diagnosis and decision aids are discussed.
