The effects of social influence on children's memory reports: the omission and commission error asymmetry

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children.     

Tracking conversational repetition: an evaluation of target monitoring ability

The ability to track who one tells information to (target monitoring) is evaluated in the present study. Participants shared personal information with target persons across four sessions spaced one day apart, and were instructed not to duplicate information to the same person over successive conversations. Target monitoring success was evaluated both on‐line, during the information sharing sessions, and retrospectively, following the final session. On‐line monitoring, or avoiding telling someone what you told them before, was very good with only one prior shared fact (Sessions 2 and 3), but declined with two prior shared facts (Session 4). Retrospective monitoring, or remembering prior fact‐to‐person assignments, was most accurate for Session 1, but dropped off sharply for Session 2 and remained constant through Session 4. Temporal errors in retrospective fact‐to‐person assignment tend to shift forward in days (telescoping). Further research is needed on the complex interrelationship of source and target information exchanges. Copyright © 2006 John Wiley & Sons, Ltd.     

Don’t hate me because I’m beautiful: Self-enhancing biases in threat appraisal

We compare people’s intuitive judgments about how the self and others respond to threat. We propose that people hold a self-enhancing belief in ”threat immunity,” i.e., they see themselves as more secure than other people in the face of threat. In Study 1, people assumed that they threatened others more than others threatened them. In Study 2, people on project teams estimated that both they and their teammates provoked roughly equal levels of threat in others, although they experienced less threat than did other people. Study 3 experimentally manipulated threat perceptions in an interactive context and revealed that when people held self-enhancing threat appraisals, those with whom they interacted experienced lower satisfaction with the outcome and relationship. Finally, Study 4 demonstrated that, as compared to people who affirmed themselves and thus focused on the self, people who affirmed another person displayed lower threat immunity. The self-enhancing nature of these threat appraisals reveals how competition and envy emerge in organizations—or at least, how people imagine they emerge.     

Biases in social comparisons: Optimism or pessimism?

Social comparisons typically lead to two kinds of biases: A comparative optimism bias (i.e., a tendency for people to view themselves as more likely than others to be the beneficiaries of positive outcomes) or a comparative pessimism bias (i.e., a tendency for people to view themselves as less likely than others to be such beneficiaries); rarely are people fully calibrated in terms of how they compare to others. However, there is little systematic research on the factors that determine when a comparative optimism versus pessimism bias will occur, how they can be attenuated and whether such attenuation is always desirable. In this paper, we report four studies which demonstrate the following key results: First, we show that perceived level of control over the outcome drives whether a comparative optimism or pessimism bias will occur (Study 1). Second, an increase in perceived similarity between self and a comparison target person attenuates the comparative optimism bias in domains that people view as highly controllable (Study 2a) and attenuates the comparative pessimism bias in domains that people view as less controllable (Study 2b). Finally, we show that people are willing to work harder when they experience more comparative optimism in higher control scenarios and when they experience less comparative pessimism in lower control scenarios, illustrating that motivating people to strive harder for positive outcomes can result from exacerbated or attenuated bias, depending on the context (Study 3).     

Attitudes Toward Sexual Harassment of Women in India1

A hypothetical incident of sexual harassment at the workplace was presented to 720 undergraduate students of the University of Bombay who attributed blame to the female victim of a superordinate male harasser and rated the appropriateness of her response to the harassment. The experiment had a 2 (Subject's Sex) × 3 (Victim's Marital Status: unmarried, married, or divorced) × 2 (Type of Harassment: verbal vs. physical) × 4 (Victim's Response: ignoring, complaining, scolding, or slapping) between-subjects factorial design with 15 subjects per cell. Male subjects blamed the victim of harassment more than female subjects, the unmarried and married victims were blamed more than the divorced victim, and the ignoring victim was blamed more than the complaining, scolding, and slapping victims. Perceived appropriateness of victim's response was higher with the divorced victim as compared to the unmarried and married victims, with physical harassment as compared to verbal harassment, and with the complaining, scolding, and slapping victims as compared to the ignoring victim. A three-way interaction on perceived appropriateness suggested that female subjects, as compared to male subjects, were more in favor of strong self-assertive action against harassment, but relatively less so in the case of the unmarried victim.     

Infant-mother attachment can be improved through group intervention: a preliminary evaluation in Spain in a non-randomized controlled trial

The quality of infant-mother attachment has been linked to competence in different domains of child development. Research indicates that early intervention can enhance the quality of infant-mother attachment, though its efficacy in a group format has yet to be evaluated. The current study is aimed at examining the usefulness of a group intervention in enhancing infant-mother attachment. An intervention aimed at addressing aspects such as maternal responsivity, sensitivity and childrearing behaviour was developed by the researchers and experienced psychologists. The intervention spanned a period of 14 months starting from the third quarter of pregnancy. The intervention was evaluated among 24 mothers from the Basque region of Spain. The sample consisted of children of both genders in a similar proportion: 45.8% were boys and 54.2% were girls. The children in this sample were full-term born and did not present symptoms of any serious pre- or postnatal complications. The intervention had a statistically non-significant medium effect. Infants whose mothers had received the intervention showed higher rates of secure attachment compared to children from the control group, as assessed by the Strange Situation observation procedure. A potentially significant confounding variable, maternal attachment, was balanced across the intervention and comparison groups. We can tentatively point out that a group intervention may enhance the quality of infant-mother attachment. Nevertheless, because the study design was not randomized, the results of this study remain preliminary and need replication in a full randomized controlled trial designed study.     

Perception of the Mccolloch Effect Correlates with Activity in Extrastriate Cortex: A Functional MagneticResonance Imaging Study

The McCollough effect is a striking color aftereffect that is linked to the orientation of the patterns used to induce it. To produce the McCollough effect, two differently oriented grating patterns, such as a red-and-black vertical grating and a green-and-black horizontal grating, are viewed alternately for a few minutes. After such colored gratings are viewed, the white sections of avertical black-and-white test grating appear to be tinged with green, and the white sections of a horizontal grating appear to be tinged with pink. We present evidence from a functional magnetic resonance imaging study that the perception of the McCollough effect correlates with increased activation in the lingual and fusiform gyriùextrastriate visual areas that have been implicated in color perception in humans.     

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.     

Do strict rules and moving images increase the reliability of sequential identification procedures?

Live identification procedures in England and Wales have been replaced by use of video, which provides a sequential presentation of facial images. Sequential presentation of photographs provides some protection to innocent suspects from mistaken identification when used with strict instructions designed to prevent relative judgements (Lindsay, Lea, & Fulford, 1991 ). However, the current procedure in England and Wales is incompatible with these strict instructions. The reported research investigated whether strict instructions would enhance the reliability of identification from video. The effect of using moving rather than still video clips was also investigated. Participants witnessed a live staged incident, and attempted to identify the culprit later from police video lineups, which were run double blind. Strict instructions produced a significantly lower rate of correct identifications in culprit present lineups, but did not significantly reduce the rate of mistaken identification in culprit absent lineups. Moving images yielded fewer mistaken identifications in culprit absent lineups. Copyright © 2006 John Wiley & Sons, Ltd.
