RESUMO

Ethnic out-group members are disproportionately more often the victim of misidentifications. The so-called other-race effect (ORE), the tendency to better remember faces of individuals belonging to one's own ethnic in-group than faces belonging to an ethnic out-group, has been identified as one causal ingredient in such tragic incidents. Investigating an important aspect for the ORE-that is, emotional expression-the seminal study by Ackerman and colleagues (2006) found that White participants remembered neutral White faces better than neutral Black faces, but crucially, Black angry faces were better remembered than White angry faces (i.e., a reversed ORE). In the current study, we sought to replicate this study and directly tackle the potential causes for different results with later work. Three hundred ninety-six adult White U.S. citizens completed our study in which we manipulated the kind of employed stimuli (as in the original study vs. more standardized ones) whether participants knew of the recognition task already at the encoding phase. Additionally, participants were asked about the unusualness of the presented faces. We were able to replicate results from the Ackerman et al. (2006) study with the original stimuli but not with more standardized stimuli.

RESUMO

Despite efforts to create dedicated smoking areas and no-smoking signs, many smokers continue to light their cigarettes in front of public building entrances-leading to concerns over health consequences for non-smokers passing by. To increase compliance with no-smoking requests, behavioral interventions that tap into habitual and automatic processes seem promising. A pseudo-randomized controlled trial was conducted to assess the differential impact of seven behavioral interventions based on Cialdini's principles of persuasion. Over a period of 9 weeks, the number of smokers was counted (total n = 17,930 observations) in front of a German University Medical Center. Relative to a baseline and a control condition, interventions based on the principles of reciprocity, scarcity, and authority were most effective in reducing the number of observed smokers in front of the building entrance (41.5%, 45.7%, and 52.1% reduction rates, respectively). Having observed smokers' behavior in vivo, this study provides substantial evidence for the impact of persuasive strategies on outdoor smoking. In the future, this knowledge should be used to protect non-smokers from second-hand smoke by increasing the use of designated smoking areas, leave to another place to smoke, or not smoke at all.

RESUMO

We investigated the role of contextual knowledge in defensive responses to visual stimuli (spiders and butterflies) looming toward the hand. Human participants responded to tactile stimuli delivered to the same hand at 6 possible locations during an insect's approach. Tactile reaction times were faster when looming stimuli were closer to the hand, especially for spiders, and faster when insects loomed on a collision path than on a near-miss path. This latter finding suggests that human reactions to looming stimuli are not merely automatic reflexes but that contextual knowledge about the trajectory of looming objects is included in predicting their impact.

RESUMO

Although self-persuasion was shown to be more effective than direct persuasion in changing attitudes and intentions, its effectiveness in different cultures remains unclear. Furthermore, research suggests that Eastern individuals tend to incorporate close others in the self to a larger extent than Western individuals. Combining both lines of research, the current studies examined whether thinking of a close other would influence the effectiveness of (self)-persuasion across cultures. Two parallel studies were conducted. U.S. participants (nstudy 1 = 195; nstudy 2 = 292) and Chinese participants (nstudy 1 = 187; nstudy 2 = 313) reported their initial attitudes and intentions toward five target behaviors prior to either think of a specific close other or not. Subsequently, they were randomly assigned to receive either a self-persuasion or a direct persuasion task. Specifically, the self-persuasion task led participants to generate own arguments or arguments that they think the close other would give; the direct persuasion task led participants to read given arguments or imagine that the arguments were from the close other. In the end, all participants reported their attitudes and intentions again after doing the persuasion tasks. The moderation effect of culture was only found in Study 1, such that direct persuasion worked more effectively in Chinese participants than self-persuasion, whereas the effectiveness of the two persuasive techniques did not differ in U.S. participants. In both studies, thinking of a close other was not found to influence the effectiveness of (self-)persuasion across cultures. Possible explanations and future research directions were discussed.

RESUMO

In joint action literature it is often assumed that acting together is driven by pervasive and automatic process of co-representation, that is, representing the co-actor's part of the task in addition to one's own. Much of this research employs joint stimulus-response compatibility tasks varying the stimuli employed or the physical and social relations between participants. In this study we test the robustness of co-representation effects by focusing instead on variation in response modality. Specifically, we implement a mouse-tracking version of a Joint Simon Task in which participants respond by producing continuous movements with a computer mouse rather than pushing discrete buttons. We have three key findings. First, in a replication of an earlier study we show that in a classical individual Simon Task movement trajectories show greater curvature on incongruent trials, paralleling longer response times. Second, this effect largely disappears in a Go-NoGo Simon Task, in which participants respond to only one of the cues and refrain from responding to the other. Third, contrary to previous studies that use button pressing responses, we observe no overall effect in the joint variants of the task. However, we also detect a notable diversity in movement strategies adopted by the participants, with some participants showing the effect on the individual level. Our study casts doubt on the pervasiveness of co-representation, highlights the usefulness of mouse-tracking methodology and emphasizes the need for looking at individual variation in task performance.

RESUMO

Despite the increase in interactions between children and robots, our understanding of children's neural processing of robotic movements is limited. The current study theorized that motor resonance hinges on the agency of an actor: its ability to perform actions volitionally. As one of the first studies with a cross-sectional sample of preschoolers and older children and with a specific focus on robotic action (rather than abstract non-human action), the current study investigated whether the perceived agency of a robot moderated children's motor resonance for robotic movements, and whether this changed with age. Motor resonance was measured using electroencephalography (EEG) by assessing mu power while 4 and 8-year-olds observed actions performed by agentic versus non-agentic robots and humans. Results show that older children resonated more strongly with non-agentic than agentic robotic or human movement, while no such differences were found for preschoolers. This outcome is discussed in terms of a predictive coding account of motor resonance. Importantly, these findings contribute to the existing set of studies on this topic by showing that, while keeping all kinematic information constant, there is a clear developmental difference in how children process robotic movement depending on the level of agency of a robot.

RESUMO

Robots are becoming an integral part of society, yet the extent to which we are prosocial toward these nonliving objects is unclear. While previous research shows that we tend to take care of robots in high-risk, high-consequence situations, this has not been investigated in more day-to-day, low-consequence situations. Thus, we utilized an experimental paradigm (the Social Mindfulness "SoMi" paradigm) that involved a trade-off between participants' own interests and their willingness to take their task partner's needs into account. In two experiments, we investigated whether participants would take the needs of a robotic task partner into account to the same extent as when the task partner was a human (Study I), and whether this was modulated by participant's anthropomorphic attributions to said robot (Study II). In Study I, participants were presented with a social decision-making task, which they performed once by themselves (solo context) and once with a task partner (either a human or a robot). Subsequently, in Study II, participants performed the same task, but this time with both a human and a robotic task partner. The task partners were introduced via neutral or anthropomorphic priming stories. Results indicate that the effect of humanizing a task partner indeed increases our tendency to take someone else's needs into account in a social decision-making task. However, this effect was only found for a human task partner, not for a robot. Thus, while anthropomorphizing a robot may lead us to save it when it is about to perish, it does not make us more socially considerate of it in day-to-day situations.

RESUMO

Previous research showed that fear-inducing graphic warning labels can lead to cognitive dissonance and defensive responses. Less threatening, social-related warning labels do not elicit these defensive responses, making them more effective in preventing smoking in adults. Given that smoking numbers are still too high among youngsters, it is crucial to investigate how warning labels should be designed to prevent teenagers from starting smoking in the first place. In two studies, we investigated whether comparable effects of social-related warning labels could be observed in a group of teenagers (14-17 years) who are not yet legally allowed to smoke. In addition, we tried to replicate earlier findings with smoking and non-smoking adults. Participants were presented with either health warning labels, social warning labels, or no warning labels. Subsequently, their explicit cognitions (i.e., risk perception, attitude toward smoking) and their implicit associations of smoking with healthiness/unhealthiness (Study 1a and Study 1b) and with positivity/negativity (Study 2a and Study 2b) were assessed. Results showed that in both studies, adult smokers had a higher risk perception and a more positive attitude toward smoking than adult non-smokers. Additionally, social warning labels lead to stronger implicit associations between smoking and negativity in Study 2 in the adult groups. In the teenage group, social warning labels lead to more positive attitudes than health warning labels in Study 2. No further effects on risk perception or implicit associations were found in the teenage group. Possible explanations are discussed.

RESUMO

Self-persuasion (i.e., generating your own arguments) is often more persuasive than direct persuasion (i.e., being provided with arguments), even when the technique is applied in media messages by framing the message as a question. It is unclear, however, if these messages are more persuasive when viewed for a long period to allow more elaboration about the message, or for a short period to reduce elaboration. In the current experiment, this is addressed by examining whether anti-alcohol posters framed as a statement (direct persuasion) or an open-ended question (self-persuasion) are more effective to reduce alcohol consumption under conditions of short- or long message exposure, compared to a control condition (no poster). Additionally, the potentially moderating roles of self-perceived alcohol identity and self-esteem on both types of persuasion are examined. Participants (N = 149) were exposed to a self-persuasion or direct persuasion anti-alcohol poster, either briefly before or continuously during a bogus beer taste task. The amount of alcohol consumed was the covert dependent variable. Contrary to expectations, both posters failed to affect alcohol consumption, regardless of exposure length. No moderation effects for self-perceived alcohol identity and self-esteem of the participants were found. Possible explanations are discussed.

RESUMO

In this experiment, we examined if participating in a Facebook group by generating antialcohol arguments (self-persuasion) is more effective than reading antialcohol posts of others (direct persuasion) in changing alcohol consumption, risk perception, and attitudes. In addition, it was examined if submitting posts moderated these effects. Participants logged into their Facebook account and joined a group that contained posts with antialcohol arguments. They either generated their own arguments with or without posting them, or read those present in the group with or without posting that they had read them. Next, participants rated movie clips in a 30-minute ad libitum drinking session in dyads, and their alcohol consumption was measured. Finally, measures of alcohol risk perception and attitudes were completed. Results show that generating antialcohol arguments-regardless of whether they are posted online-is effective in increasing alcohol risk perception but does not affect immediate alcohol consumption.

RESUMO

Among elderly, the use of serious games steadily increases. Research shows that anthropomorphising digital agents (i.e., ascribing human characteristics to them) has positive short-term consequences on interactions with digital agents. However, whether these effects can also be observed over a long-term period and in a real-life setting is unknown. In two studies, we investigated the important long-term consequences of anthropomorphism among older adults (age > 50) to increase involvement in serious games. Participants read either a story that highly anthropomorphized the digital agent of a training game, or a low anthropomorphism story about that agent. To investigate long-term effect, they played the training game for three weeks, and gaming data was assessed (number of games played, time of playing, points gained). While on the short-term, the anthropomorphic story increased the humanness of the agent (Study 1), no long-term effects where found (Study 2). Furthermore, an anthropomorphic story had no influence on the gaming outcome. Our results inform app developers about which techniques are useful to humanise digital agents.

RESUMO

Little is known about what exactly differentiates metacognitive processes from ordinary cognitive processes particularly early in development, and the underlying developmental aspects. To examine the time-course of metacognition, the present study investigated the neural underpinnings of judgments of learning (JoLs) and compared them with control judgments, using an event-related potentials (ERP) design. During ERP recording, children age seven to eight were presented with cue-target picture pairs and instructed to learn these pairs. After each pair, they either had to make a JoL (assess the likelihood of remembering the target when only presented with the cue) or a colour judgment (indicate whether the colour yellow had been present in one of the two pictures presented earlier). Results revealed a late slow wave divergence maximal pronounced from 550 ms to 950 ms post-stimulus that distinguished between JOLs and colour judgments. Over centro-parietal areas, JoLs showed a more negative going slow wave compared to the colour judgments, and this pattern was independent of performance. The results are in support of theories that assume a distinction between metacognitive and cognitive processes.

RESUMO

Self-persuasion (self-generation of arguments) is often a more effective influence technique than direct persuasion (providing arguments). However, the application of this technique in health media communications has received limited attention. In two experiments, it was examined whether self-persuasion can be successfully applied to antialcohol media communications by framing the message as an open-ended question. In Experiment 1 (N = 131) cognitive reactions to antialcohol posters framed either as open-ended questions or statements were examined. In Experiment 2 (N = 122) the effectiveness of this framing to reduce actual alcohol consumption was tested. Experiment 1 demonstrated that exposure to an antialcohol poster framed as an open-ended question resulted in more self-generated arguments for drinking less alcohol and more favorable message evaluations than framing the same message as a statement. Experiment 2 showed that the self-persuasion poster did not affect the choice to consume alcohol but did reduce alcohol consumption for individuals who chose to drink any alcohol, compared with a direct persuasion poster or no intervention. Together, the results demonstrated the potential of self-persuasion in persuasive media messages for interventions aimed at alcohol consumption reduction specifically and for health communication in general.

RESUMO

The current study was designed to examine whether 1-year-old infants relate the perception of others' being touched to their own sensorimotor system, and whether they distinguish between animate and inanimate targets. During electroencephalography (EEG) assessment, infants watched video sequences in which either a human or a nonhuman target was touched/not touched by another object. Comparisons of sensorimotor alpha activation (7-9 Hz) on centro-parietal electrodes revealed differential cortical reactivity to the touch versus nontouch situations for the human versus the nonhuman target. Our findings provide preliminary evidence for the claim that infants might relate others' sensory experiences to their own sensorimotor system.

RESUMO

Metacognitive assessment of performance has been revealed to be one of the most powerful predictors of human learning success and academic achievement. Yet, little is known about the functional nature of cognitive processes supporting judgments of learning (JOLs). The present study investigated the neural underpinnings of JOLs, using event-related brain potentials. Participants were presented with picture pairs and instructed to learn these pairs. After each pair, participants received a task cue, which instructed them to make a JOL (the likelihood of remembering the target when only presented with the cue) or to make a control judgment. Results revealed that JOLs were accompanied by a positive slow wave over medial frontal areas and a bilateral negative slow wave over occipital areas between 350ms and 700ms following the task cue. The results are discussed with respect to recent accounts on the neural correlates of judgments of learning.

RESUMO

Major depressive disorder (MDD) has been associated with abnormalities in speech and behavioural mimicry. These abnormalities may contribute to the impairments in interpersonal functioning that are often seen in MDD patients. MDD has also been associated with disturbances in the brain serotonin system, but the extent to which serotonin regulates speech and behavioural mimicry remains unclear. In a randomized, double-blind, crossover study, we induced acute tryptophan depletion (ATD) in individuals with or without a family history of MDD. Five hours afterwards, participants engaged in two behavioural-mimicry experiments in which speech and behaviour were recorded. ATD reduced the time participants waited before speaking, which might indicate increased impulsivity. However, ATD did not significantly alter speech otherwise, nor did it affect mimicry. This suggests that a brief lowering of brain serotonin has limited effects on verbal and non-verbal social behaviour. The null findings may be due to low test sensitivity, but they otherwise suggest that low serotonin has little effect on social interaction quality in never-depressed individuals. It remains possible that recovered MDD patients are more strongly affected.

RESUMO

In the present study we investigated whether differences in the sense of agency influenced the effectiveness of both direct persuasion and self-persuasion techniques. By manipulating both the delay and contingency of the outcomes of actions, participants were led to experience either a low or high sense of agency. Participants were subsequently presented with arguments as to why a clean local environment is important (direct persuasion), or were asked to generate those arguments themselves (self-persuasion). Subsequently, participants' cleanliness attitudes and willingness to participate in a campus cleanup were measured. The results show that techniques of direct persuasion influenced attitudes and volunteering behavior under conditions of low rather than high agency, whereas techniques of self-persuasion were most effective under conditions of high rather than low agency. The present findings therefore show how recent experiences of agency, a state based experience of control, can influence the effectiveness of both external and internal persuasion techniques.

RESUMO

The way we experience the space around us is highly subjective. It has been shown that motion potentialities that are intrinsic to our body influence our space categorization. Furthermore, we have recently demonstrated that in the extrapersonal space, our categorization also depends on the movement potential of other agents. When we have to categorize the space as "Near" or "Far" between a reference and a target, the space categorized as "Near" is wider if the reference corresponds to a biological agent that has the potential to walk, instead of a biological and non-biological agent that cannot walk. But what exactly drives this "Near space extension"? In the present paper, we tested whether abstract beliefs about the biological nature of an agent determine how we categorize the space between the agent and an object. Participants were asked to first read a Pinocchio story and watch a correspondent video in which Pinocchio acts like a real human, in order to become more transported into the initial story. Then they had to categorize the location ("Near" or "Far") of a target object located at progressively increasing or decreasing distances from a non-biological agent (i.e., a wooden dummy) and from a biological agent (i.e., a human-like avatar). The results indicate that being transported into the Pinocchio story, induces an equal "Near" space threshold with both the avatar and the wooden dummy as reference frames.

RESUMO

In the present study, we investigated the test-retest stability of resting state alpha asymmetry in 18 children (9 male and 9 female) in a longitudinal design. Children's resting state brain activation asymmetries were assessed by means of EEG first after 14 months of age, and again a second time at 83 months of age, and frontal (AsymF), temporal (AsymT), and parietal (AsymP) alpha activation asymmetries were calculated. Analyses demonstrate positive relations between frontal asymmetry scores at 14 and 83 months of age. Temporal and parietal asymmetries did not show this stability over time. This finding provides further support for the use of frontal alpha asymmetry measures to investigate processes underlying emotion and motivation in childhood, and its stability over time.
