Minimizing Intergroup Contact: An Urban Field Study

This study examines the effects of observing the negative or neutral behavior of a black or a white couple on white subjects' subsequent social interactions with either a black or a white person. Subjects encountered either a black or a white couple having an argument or a neutral interaction. Shortly thereafter the subjects were approached by either a black or white male confederate who asked for directions. A 2 (Couple's Race) × 2 (Couple's Behavior) × 2 (Confederate's Race) analysis of variance revealed that white subjects interacted with a black confederate for a shorter period of time after having observed a black couple's argument.     

Applying imagined contact to improve physiological responses in anticipation of intergroup interactions and the perceived quality of these interactions

This experiment (N = 49) is the first to show that imagined contact can buffer anticipatory physiological responses to future interactions, and improve the quality of these interactions. Participants imagined a positive interaction with a person with schizophrenia, or in a control condition, a person who did not have schizophrenia. They then interacted with a confederate whom they believed had schizophrenia. Participants in the imagined contact condition reported more positive attitudes and less avoidance of people with schizophrenia, displayed smaller anticipatory physiological responses, specifically smaller changes in interbeat interval and skin conductance responses, and had a more positive interaction according to the confederate. These findings support applying imagined contact to improve interactions with people with severe mental illnesses.     

Increased conformity to a fellow deviant as a function of prior deviation

A subject was induced to publically report his opinions on a variety of issues. A group of confederates disagreed with the subject; one confederate agreed with him. Thus, the subject deviated from the majority of the group, but received social support from one other individual. Each subject was then paired with one individual from the previous group, and regardless of his pairing, was subjected to a constant amount of conformity pressure from the confederate on a new set of judgments. Deviant subjects conformed more to the confederate who had previously given them social support than they did to a previous majority member. This increased conformity was found in two studies, (1) females judging physical realities and, (2) males reporting their opinions on attitudinal issues. Ratings taken in the second study demonstrated that the deviant subject felt increased liking for and similarity to the confederate who initially provided him with social support, but comparisons between various experimental groups indicated conformity to a confederate was not completely predictable from the subject's liking for that confederate. Instead, conformity was greatest following an experience of deviation from the majority.     

Changing the criterion for memory conformity in free recall and recognition

People's responses during memory studies are affected by what other people say. This memory conformity effect has been shown in both free recall and recognition. Here we examine whether accurate, inaccurate, and suggested answers are affected similarly when the response criterion is varied. In the first study, participants saw four pictures of detailed scenes and then discussed the content of these scenes with another participant who saw the same scenes, but with a couple of details changed. Participants were either told to recall everything they could and not to worry about making mistakes (lenient), or only to recall items if they were sure that they were accurate (strict). The strict instructions reduced the amount of inaccurate information reported that the other person suggested, but also reduced the number of accurate details recalled. In the second study, participants were shown a large set of faces and then their memory recognition was tested with a confederate on these and fillers. Here also, the criterion manipulation shifted both accurate and inaccurate responses, and those suggested by the confederate. The results are largely consistent with a shift in response criterion affecting accurate, inaccurate, and suggested information. In addition we varied the level of secrecy in the participants’ responses. The effects of secrecy were complex and depended on the level of response criterion. Implications for interviewing eyewitnesses and line-ups are discussed.     

Co‐Witness Confidence,Conformity, and Eyewitness Memory: An Examination of Normative and Informational Social Influences

We explored conformity and co‐witness confidence in eyewitness memory. Confederates provided misleading information and confidence ratings during a cued recall test, and participants publicly provided answers to this test in turn. Participants performed memory tests with a confederate, then completed individual memory tests. Results indicated that confederates who answered questions prior to participants impacted their public and private memory reports for accurate information but only impacted public reports for misleading information. Participants' confidence in their performance in the presence of a confederate mirrored the confederate's confidence levels, suggesting a confidence conformity effect. Results are explained in terms of differential effects of informational and normative influence for accuracy and confidence in co‐witness memory reports.

Likable co-witnesses increase eyewitness accuracy and decrease suggestibility

This study examines the impact of likability on memory accuracy and memory conformity between two previously unacquainted individuals. After viewing a crime, eyewitnesses often talk to one another and may find each other likable or dislikable. One hundred twenty-seven undergraduate students arrived at the laboratory with an unknown confederate and were assigned to a likability condition (i.e., control, likable or dislikable). Together, the pair viewed pictures and was then tested on their memory for those pictures in such a way that the participant knew the confederate's response. Thus, the participant's response could be influenced both by his or her own memory and by the answers of the confederate. Participants in the likable condition were more accurate and less influenced by the confederate, compared with the other conditions. Results are discussed in relation to research that shows people are more influenced by friends than strangers and in relation to establishing positive rapport in forensic interviewing.     

Perceived Similarity in Interracial Attitudes and Behaviors: The Effects of Belief and Dialect Style1

The present study investigated the role of two types of similarity (attitude similarity and dialect style) on interpersonal attitudes and behaviors in a face-to-face interaction. Sixty subjects interacted with an experimental confederate who was either black or white, spoke either standard white English or a black dialect, and whom the subject perceived as agreeing or disagreeing on an attitude questionnaire. Subjects' nonverbal behavior during the interaction was coded using Mehrabian's scheme of immediacy cues, and attitudes toward the confederate were measured via questionnaire following the interaction. Subjects showed more favorable attitudes toward the white than black confederate and had more positive attitudes toward the black confederate when she spoke white English. Contrary to previous findings, no significant main effect was found for belief similarity. While no significant mean differences were obtained between conditions for the nonverbal measures, correlations between these measures and a measure of likinglfriendship indicated that this relationship differed depending on the race of the confederate and the dialect used. The results are discussed in terms of their implications for the role of perceived similarity in interracial interaction.     

It hurts when I do this (or you do that): Posture and pain tolerance

Recent research (Carney, Cuddy, & Yap, 2010) has shown that adopting a powerful pose changes people's hormonal levels and increases their propensity to take risks in the same ways that possessing actual power does. In the current research, we explore whether adopting physical postures associated with power, or simply interacting with others who adopt these postures, can similarly influence sensitivity to pain. We conducted two experiments. In Experiment 1, participants who adopted dominant poses displayed higher pain thresholds than those who adopted submissive or neutral poses. These findings were not explained by semantic priming. In Experiment 2, we manipulated power poses via an interpersonal interaction and found that power posing engendered a complementary (Tiedens & Fragale, 2003) embodied power experience in interaction partners. Participants who interacted with a submissive confederate displayed higher pain thresholds and greater handgrip strength than participants who interacted with a dominant confederate.     

Induced Reminiscence of Love and Chivalrous Helping

This study tested the effect of semantically-induced thoughts of love on chivalrous helping. A field setting of four hundred and one participants was divided into two groups. One group was interviewed and asked to retrieve the memory of a love episode, and the second group, the control group, was asked to retrieve a piece of music that they love. The two groups encountered another confederate, who inadvertently lost a stack of compact discs when they neared each other. The results demonstrated that participants were more helpful when they were male, when the person in need of help was female, and when they were induced to retrieve the memory of a love episode.     

Walking through doorways causes forgetting: active and passive interaction

ABSTRACT

The current study explored the location updating effect when people passively interacted with an environment. This was assessed experimentally by having one person actively navigate through a virtual environment while picking up and putting objects down. A second person passively viewed the movement. Both participants responded to memory probes for objects they encountered. Probes appeared when the active participant moved halfway across a room or immediately after moving into a new room. Consistent with previous research, a location updating effect was found. That is, memory was worse following a shift to a new room. This effect was found for both active and passive participants but was smaller for the passive group. Thus, the shift from one event to another causes information to be harder to remember, reinforcing the importance of event cognition in memory. However, the more involved a person is in the interactive event, the more pronounced the effects.     

Situation-specific variables as determinants of perceived environmental aesthetic quality and perceived crowdedness

It was hypothesized that relevant situation-specific variables may act along with objective physical conditions to determine environmental perception, and that the exclusive use of the physical level of an environmental stimulus to predict behavior may, therefore, be inadequate. A 2 × 4 between-subjects design was employed in which an attitudinally similar or dissimilar confederate interacted with a subject at one of four distances. As hypothesized, subjects who interacted with a similar confederate judged the environment to be of higher aesthetic quality, perceived themselves to be less crowded, and felt affectively more positive than subjects who interacted with a dissimilar other. The results were also interpreted as supporting the utility of the Byrne-Clore (1970) reinforcementaffect model of evaluative responses as a means of predicting environmental perception and the behavioral response to environmental stimuli.     

I still think it was a banana: memorable 'lies' and forgettable 'truths'

Interpersonal influences on cognition can distort memory judgements. Two experiments examined the nature of these 'social' influences, and whether their persistence is independent of their accuracy. Experiment 1 found that a confederate's social proximity, as well as the content and the confidence of their utterances, interactively modulates participants' immediate conformity. Notably, errant confederate statements that 'lied' about encoded material had a particularly strong immediate distorting influence on memory judgements. Experiment 2 revealed that these 'lies' were also memorable, continuing a day later to impair memory accuracy, while accurate confederate statements failed to produce a corresponding and lasting beneficial effect on memory. These findings suggest that an individual's 'informational' social influence can be selectively heightened when they express misinformation to someone who suspects no deceptive intent. The methods newly introduced here thus allow multiple social and cognitive factors impinging on memory accuracy to be manipulated and examined during realistic, precisely controlled dyadic social interactions.     

Social anxiety moderates memory conformity in adolescents

When two people view the same event and later try to remember it together, what one person says affects what the other person reports. A model is presented which predicts that this memory conformity effect will be moderated, in different ways, by two components of social anxiety. People with higher fear of negative evaluation should be more influenced by their peers than others, but those with higher social anxiety related to avoiding social situations may be less influenced by their peers than others. Pairs of adolescent‐aged participants took part in a face recognition study. For each trial one person responded and then the next person responded. The effect of what the first person said on the second person's response was measured; the size of the effect was moderated by the social anxiety measures as predicted by the model. This is the first study showing the relationship between social anxiety and memory suggestibility. Copyright © 2009 John Wiley & Sons, Ltd.     

Mediating Role of Memory of Another Person's Choicein Social Influence on Preference

We often tend to fit our subjective preference with those of others after merely being faced with what other people prefer. This is known as social conformity. However, it is still unclear how the impact of such a social influence on subjective preference is modulated by the personal characteristics of the other person (e.g., whether the person is trustworthy) and the explicit memory of those personal characteristics (e.g., remembering who evaluated the objects). To clarify explicit memory's underlying role regarding social influence, we asked participants to evaluate their preference for abstract paintings both before and after observing binary choices made by others whose behaviors could be labeled as trustworthy, neutral, or untrustworthy. The results showed the following: (a) even without explicit memory of who made a choice and which painting was chosen, the participants preferred chosen over unchosen paintings; and (b) such preference changes were modulated by the subjective trustworthiness of others only when they explicitly remembered who made a choice.     

Social influences on reality-monitoring decisions

A modified Asch (1951) conformity paradigm was used to study the impact of social influence on reality-monitoring decisions about new items. Subjects studied pictures of some objects and imagined others. In a later test phase, they judged whether items had been perceived in the study phase, had been imagined, or were new. Critically, for some items, the subjects were informed of a confederate's response before rendering a judgment. Although the confederate was always correct when they responded to old items, for new items, the confederate responded perceived, imagined, or new, or did not respond (baseline). In two experiments, we show that memory for new items was influenced by an erroneous response of the confederate. Social conformity was reduced by undermining the credibility of the confederate (Experiments 1A and 1B), and the confederate's influence was evident even after there was only a 20-min delay between study and test (Experiment 2), when the subjects were 87% accurate on new baseline items. These experiments reveal the power of social influence on reality-monitoring accuracy and confidence.     

Memory conformity: Disentangling the steps toward influence during a discussion

When two people see the same event and discuss it, one person’s memory report can influence what the other person subsequently claims to remember. We refer to this asmemory conformity. In the present article, two factors underlying the memory conformity effect are investigated. First, are there any characteristics of the dialogue that predict memory conformity? Second, is memory conformity differentially affected when information is encountered that omits, adds to, or contradicts originally encoded items? Participants were tested in pairs. The two members of each pair encoded slightly different versions of complex scenes and discussed them prior to an individual free recall test. The discussions were audiotaped, transcribed, and analyzed. Our most striking finding was that the witness initiating the discussion was most likely to influence the other witness’s memory report. Furthermore, witnesses were most likely to be influenced when an additional (previously unseen) item of information was encountered in the discussion.     

The Effects of Effort on Helping the Physically Disabled

Abstract

Interactions with physically disabled people often elicit both the desire to avoid the stigmatized and dependent person and feelings of responsibility to help the disadvantaged. This study examined the effort required to help, the helper's gender, and the help received by disabled and nondisabled confederates in searching for a lost object. One confederate was actually disabled and totally dependent on others for completing the helping task, but the other confederate was not disabled. Results indicated a significant interaction of effort and confederates' level of ability. Post hoc tests indicated no differences in helping disabled and nondisabled confederates in the low-effort condition, but, in the high-effort condition, the disabled confederate received significantly more help. These findings suggest that when costs of helping were low, decisions about helping each confederate did not appear to differ; but when costs were high, feelings of social responsibility outweighed both the additional effort involved and tendencies for avoidance in decisions to help the disabled confederate.     

I saw it for longer than you: the relationship between perceived encoding duration and memory conformity

The memory conformity effect is when people's memories become similar to one another's following a discussion. The present study examined whether an individual's beliefs in the quality of their memory, relative to another person's, mediates susceptibility to memory conformity. Perceived encoding duration was manipulated by telling dyad members that one person had encoded a set of pictures for either half or twice as long as their partner. In fact, actual encoding duration was the same for all participants. Dyad members each encoded slightly different versions of otherwise identical pictures and discussed them prior to an individual free recall test. Participants who believed that they had encoded the pictures for half as long as their partner were more susceptible to memory conformity, as indicated by their increased tendency to report errant items at test that had been encountered from their partner rather than items that they had actually seen. This effect of perceived encoding duration on memory conformity was mediated through response order. A source monitoring test found that these unseen items were errantly attributed to the pictures approximately 50% of the time. The findings are discussed in relation to the role of metamemory in susceptibility to memory conformity.
