Memory conformity for confidently recognized items: The power of social influence on memory reports

Memory conformity occurs when one person's memory report influences another's. Memory conformity is more likely to occur when the information comes from a credible source, and when internal evidence is weak. Here, we investigate whether there are situational variations in how heavily participants weigh internal cues to accuracy when confronted with conflicting information from a partner. The results show that even confidently held memories are subject to influence from external sources, and that social influence is exaggerated when the source is seen to be highly credible.     

Memory conformity and the perceived accuracy of self versus other

Here, we demonstrate that the decision to conform to another person’s memory involves a strategic trade-off that balances the accuracy of one’s own memory against that of another person. We showed participants three household scenes, one for 30 s, one for 60 s, and one for 120 s. Half were told that they would encode each scene for half as long as their virtual partner, and half were told that they would encode each scene for twice as long as their virtual partner. On a subsequent two-alternative-forced choice (2AFC) memory test, the simulated answer of the partner (accurate, errant, or no response) was shown before participants responded. Conformity to the partner’s responses was significantly enhanced for the 30-s versus the 60- and 120-s scenes. This pattern, however, was present only in the group who believed that they had encoded each scene for half as long as their partner, even though the short-duration scene had the lowest baseline 2AFC accuracy in both groups and was also subjectively rated as the least memorable by both groups. Our reliance on other people’s memory is therefore dynamically and strategically adjusted according to knowledge of the conditions under which we and other people have acquired different memories.     

BAND AID: First steps toward an ICAI system

BANDAID is an intelligent computer-assisted instruction (ICAI) system designed for students learning to program in BASIC. The major thesis is that beginning students need a friendly environment, that is, one in which information about the language and the system are immediately available. The system accepts most commands without switching levels: BASIC lines are parsed on input with very specific error messages. An editor allows corrections of BASIC lines. The program can be traced while running, and an indefinite number of HELP comments can be written for the system. Without leaving the BASIC environment, the user can interact with the CMS monitor of the main machine running the program. Although no English language comments or questions are allowed, the system is modular so that additions of restrictive dialogue interaction and guided tutoring are possible. Illustrations are presented showing the capabilities of the system. The paper also presents some of the implementation details of BANDAID. A flexible system requires implementation in LISP, so examples of how the system programmer interacts with LISP during debugging are given. Although still incomplete, the system runs satisfactorily and can be used easily by beginning students and by psychologists interested in how people learn complex subjects.     

Getting started: Charles Darwin's early steps toward a creative life in science

Charles Darwin's original and important contributions to science resulted from commitment, persistence, and hard work throughout his adult life. How, when, and where Darwin developed these prerequisites for creative thinking is the focus of this paper. Using a cognitive case study approach to examine the rich record of Darwin's life and work indicates that the 1 &frac; years he spent in Edinburgh as a medical student when he was 16–18 years old was the major turning point in his transformation from a hobbyist into a scientist. Darwin first found hisvoice in science in Edinburgh during late adolescence.     

Internalization versus compliance: Differential processes underlying minority influence and conformity

Two experiments investigated whether minority influence and conformity operate by the same or by different processes. It was predicted that subjects who were simultaneously exposed to a majority and a minority opinion would move towards the minority in private but towards the majority in public. The results of Experiment 1 supported this hypothesis. Experiment 2 investigated three hypotheses predicting that (1) the above interaction would be replicated, (2) minorities would trigger more arguments and counter-arguments, and (3) cognitive activity would mediate internalization but not compliance. Hypotheses 1 and 3 were supported. The second hypothesis was not supported. However, minorities were found to trigger more arguments and fewer counter-arguments than majorities. The results were interpreted as supporting the dual process model.     

Being imitated, conformity, and social influence: An integrative review

The recently developed literature on the effects of being imitated and the social influence function of imitation are reviewed, as is related literature on conformity from social psychology. Then, this research is considered within a number of theoretical contexts, but especially within the conceptual framework of Byrne's elaboration of effectance motivation. Finally, questions are raised which need to be addressed in future research.     

Minority influence: the role of ambivalence toward the source

According to literature on social influence, a minority source may indirectly influence group members by fostering ambivalent reactions. Two studies were carried out in order to provide empirical support for this theoretical assumption. In Study 1 participants (n = 133), were exposed to a counter‐attitudinal minority message and ambivalence was manipulated by facilitating the accessibility of either ambivalent (positive and negative) or univalent (positive or negative) thoughts toward the source. We predicted and found more indirect influence in ambivalent condition than in univalent conditions. No effect of ambivalence on direct influence was found. In Study 2 (n = 127), ambivalence was measured and two possible antecedents of ambivalence, consistency of the minority and personal relevance of the topic for participants, were taken into account. Findings suggest that ambivalence mediates the effects of the two factors on indirect influence. In sum, these studies provide evidence of the importance of ambivalence in minority influence context, an early assumption that was still lacking in strong empirical support.

The influence of mood on the intensity of emotional responses: Disentangling feeling and knowing

The results of three experiments suggest that pre-existing mood increases the intensity of affectively congruent emotions while dampening the intensity of incongruent emotions independent of attributional knowledge. This result was obtained using a new method for inducing mood states unobtrusively and with minimal or no cognitive concomitants. The results of Experiment 1 revealed that for participants who were exposed to positive feedback a pre-existing positive mood led to stronger feelings of pride in comparison to negative mood. The results of Experiments 2 and 3 suggest that pre-existing mood directly influences the experience of subsequently elicited emotions independent of what one knows about the causes of this feeling. When participants were required to differentiate between the funniness of a cartoon and their subjective humour response, mood influenced only the latter judgement (Experiment 2). In Experiment 3, reminding participants of the mood induction resulted in a contrast effect in judging the funniness of a cartoon. However, the pre-existing mood continued to exert an assimilation effect on the overt mirth response. In conclusion, these results suggest that the feeling and knowledge component are partly independent bases of emotional responses.     

Improving outgroup attitudes in schools: First steps toward a teacher‐led vicarious contact intervention

Despite the urgent need for promoting positive intergroup relations in schools, research on intergroup relations is not systematically translated into prejudice‐reduction interventions. Although prejudice‐reduction interventions in schools based on indirect contact have been conducted for decades, they have all been carried out by researchers themselves. In a field experiment in Finland in autumn 2015, we tested for the first time a vicarious contact prejudice‐reduction intervention for its effectiveness among adolescents (N = 639) when implemented independently by school teachers instead of researchers. In addition, we tested the extent to which the intervention's effect depends on initial outgroup attitudes, previous direct outgroup contact experiences, and gender, hypothesizing that the intervention improves outgroup attitudes particularly among adolescents with more negative prior attitudes and less positive prior direct contact, and more among girls than among boys. We found an unanticipated overall deterioration in the outgroup attitudes during intervention in both the experimental and control groups. However, attitudes seemed to deteriorate somewhat less in the experimental than in the control group, and the intervention had a significant positive effect on outgroup attitudes in one experimental subgroup that needed it most: girls who had negative rather than positive outgroup attitudes at the outset. We discuss our results in light of previous research and contextual particularities.     

Putting the brakes on aggression toward a romantic partner: the inhibitory influence of relationship commitment

Why do people behave aggressively toward romantic partners, and what can put the brakes on this aggression? Provocation robustly predicts aggression in both intimate and nonintimate relationships. Four methodologically diverse studies tested the hypothesis that provocation severity and relationship commitment interact to predict aggression toward one's romantic partner, with the aggression-promoting effects of provocation diminishing as relationship commitment increases. Across all four studies, commitment to one's romantic relationship inhibited aggression toward one's partner when individuals were severely (but not mildly) provoked. Study 4 tested the hypothesis that this Partner Provocation × Commitment interaction effect would be strong among individuals high in dispositional tendencies toward retaliation but weak (perhaps even nonexistent) among individuals low in such tendencies. Discussion emphasizes the importance of understanding instigating, impelling, and inhibiting processes in the perpetration of aggression toward intimate partners.     

Space contraction experiences during acoustic metronomic stimulation: a synthetic discussion

On the basis of the results of a previous research, we will present a new interpretation of some psychophysiological component of spatial experience. The research examined the role of the acoustic activity of a metronome (with different frequencies of 66, 144, 192/min) on a space estimation between two points. The stimulus distances between the points were 30, 60, 90 cm. Increasing the metronomic frequency determines an evident contraction of the estimation of the perceived distances for each of the three different stimulus distances. The results have been interpreted in light of a psychophysiological integrated model.     

Memory of self-performed tasks: Self-performing during recognition

Two experiments focused on whether performing actions described by to-be-remembered phrases during recognition enhances recognition compared with results of a standard verbal recognition test. The enhancement was predicted when the actions described by the phrases had been performed during study, but not when the phrases were verbally encoded by simply listening to and memorizing the material. Both experiments showed that enactment prior to recognition improved memory performance, but only when subjects had encoded by enactment. Experiment 1 also demonstrated that this test-procedure effect was independent of a bizarreness effect, which was observed only with the verbal encoding task. Experiment 2 showed that the effect of enactment during recognition was reduced when subjects used different hands for performing the actions during study and recognition- The findings support the assumption that some kind of motor memory record underlies the enactment effect that occurs when actions are performed during recognition.     

Sex differences on a measure of conformity: comments on a recent study

Reysen and Reysen's recent article made a contribution to understanding of sex differences by interpreting the results through the lens of conformity research. Reinterpretation could refer to differences in perceptual sensitivity. The results, then, are theoretically and empirically consistent with the literature.
