Source credibility and syllogistic reasoning

Two experiments examined whether a source credibility effect would be observed for a syllogistic reasoning task. In the experiments, people were given two statements, presented as the results from a survey, followed by a conclusion that was supposedly made by one of two sources. In Experiment 1, one of the sources was described as honest and the other as dishonest, and in Experiment 2, one of the sources was described as an expert and the other as a non-expert. Because a pilot experiment showed that credibility can be overridden by people’s experience with a source, all conclusions in Experiments 1 and 2 were ones that were likely to be accepted (i.e., necessary and possible strong conclusions). Both experiments showed a clear source credibility effect, particularly for the invalid conclusions. These results, along with the belief bias effect and previous research with conditional reasoning, suggest that people can be influenced by extraneous context, such as the honesty or expertise of a source, in a syllogistic reasoning task.     

Source credibility and the processing of refutation texts

The knowledge revision components framework (KReC) outlines the basic comprehension processes and text factors that can be accentuated to increase the potential for knowledge revision during reading. The goal of the present study was to explore source credibility as one such text factor. In Experiment 1, we established the utility of a set of refutation texts in influencing knowledge revision. Participants read ten refutation and ten control texts. The participants had faster reading times and higher posttest scores for the refutation than for the control texts, providing evidence for knowledge revision. In Experiment 2, we examined the influence of source credibility under normal reading conditions. Participants read 20 refutation texts, ten with high-credibility and ten with low-credibility sources. The reading times and posttest scores suggested that knowledge revision unfolded successfully, independent of credibility. Using the same texts, in Experiment 3 we examined the influence of direct instructions that made the credibility of the source of information more salient. When the credibility of the source was made salient, the revision process was disrupted in the low-credibility condition, as evidenced by slower reading times and lower posttest scores than in the high-credibility condition. The results add to our understanding of the factors that constrain knowledge revision during the reading of refutation texts, and are discussed in the context of the extant literature and KReC.     

Source variability and recall of auditory material

Recall of auditory narrative material was measured under three conditions of presentation. These were a single source condition with material from one speaker, a four source fired sequence condition with material from four speakers in a fired sequence of 3-sec. lengths, and a four source random condition with material from four speakers in a random sequence of 3-sec. lengths. Recall was better for the single source condition than for the four source conditions. No significant difference was found between the fixed and random sequential presentations. Results are discussed in terms of the attentional behaviors involved in the tasks.

Recall of auditory narrative material was measured under three conditions of presentation. These were a single source condition with material from one speaker, a four source fixed sequence condition with material from four speakers in a fixed sequence of 3-sec. lengths, and a four source random condition with material from four speakers in a random sequence of 3-sec. lengths. Recall was better for the single source condition than for the four source conditions. No significant difference was found between the fixed and random sequential presentations. Results are discussed in terms of the attentional behaviors involved in the tasks.     

Influence of recorder affect on the content of behavioural diaries and the recall of behaviours

Two experiments are described. In Experiment 1, supervisors (N = 4) kept daily performance diaries for each of four subordinates over an eight‐week period. In Experiment 2, students (N = 48) kept behavioural diaries for their instructor over a three‐week period. Daily measures of positive and negative affect were used to predict the favourability, person‐typicality and behavioural specificity of diary entries. Diary‐keepers tended to record behaviours that were consistent with their affect levels. Analyses of the variability of the favourability and person‐typicality ratings further suggested that high negative affect induced diary‐keepers to make fine discriminations among events, while high positive affect induced diary‐keepers to perceive events as similar. Diary‐keeper affect and the three diary content variables were used to predict memory for the diary entries. Diary‐keepers in Experiment 1 reported higher recall for negative behaviours than for positive behaviours, particularly if the behaviours were typical of others. This same negativity effect in recall emerged in Experiment 2, but only when there was low consistency in the positive affect experienced by diary‐keepers at encoding and recall.

Source memory in the absence of successful cued recall

Five experiments were conducted to address the question of whether source information could be accessed in the absence of being able to recall an item. The authors used a paired-associate learning paradigm in which cue-target word pairs were studied, and target recall was requested in the presence of the cue. When target recall failed, participants were asked to make a source judgment of whether a man or woman spoke the unrecalled item. In 3 of the 5 experiments, source accuracy was at or very close to chance. By contrast, if cue-target pairs were studied multiple times or participants knew in advance of learning that a predictive judgment would be required, then predictive source accuracy was well above chance. These data are suggestive that context information may not play a very large role in metacognitive judgments such as feeling-of-knowing ratings or putting one into a tip-of-the-tongue state without strong and specific encoding procedures. These same results also highlight the important role that item memory plays in retrieving information about the context in which an item was experienced.     

Exercise attitudes and behaviours among retired female collegiate athletes

ObjectivesThe present study explored exercise attitudes and behaviours among retired female collegiate athletes.DesignA survey design incorporating both closed and open-ended questions was adopted.MethodA total of 218 former NCAA Division I female athletes (n = 144 gymnastics; n = 74 swimming/diving) provided details on their current exercise behaviours and their thoughts regarding exercise since retiring from collegiate sport.ResultsNo relations were found between years since retirement and athletes’ current exercise frequency, types of exercise activities, and reasons for exercising. Despite reporting activity levels consistent with recommendations (5 days/week, 1 h per session), retired athletes remained dissatisfied with their activity levels and struggled to integrate exercise alongside occupational, academic and social demands.ConclusionsAthletes may require support in adapting to an independent and less intense exercise regime on retirement. Future research may look to explore exercise attitudes and behaviours among retired athletes from a longitudinal perspective.     

Pro-environmental attitudes,pro-environmental behaviours and nature-relatedness: Differences based on place preference

IntroductionThis study explored whether place preference, an individual's relationship with place, differentiated people on pro-environmental attitudes, nature-relatedness and pro-environmental behavior.ObjectiveThe aim was to provide a way to segment people and potentially inform behavior change messaging strategies targeting pro-environmental action.MethodOnline participants reported an urban/nature place preference, completed a sense of place measure in reference to this categorisation, followed by counter-balanced nature-relatedness, pro-environmental attitudes and pro-environmental behaviour measures.ResultsParticipants reported moderate-to-high levels of sense of place generally and place attachment specifically. Positive associations between sense of place, nature relatedness, pro-environmental attitudes and behaviours existed; but differed by place preference. Correlations were positive in the nature preference group but negative or non-significant in the urban preference group. Individuals with a nature preference reported higher nature-relatedness, pro-environmental attitudes and pro-environmental behavior.ConclusionThe results suggest place preference can discriminate individuals on a range of pro-environmental concepts and may have potential for behavior change strategies targeting these outcomes.     

Exploring the relationships between pedestrian behaviours and traffic safety attitudes in six countries

The majority of cross-cultural research on traffic safety has investigated driver behaviour, yet in most low- and middle-income countries, where the weight of the road fatality burden is felt, motorisation rates are significantly lower than in higher-income countries. As such, this approach necessarily excludes large parts of the populations in those settings. In order to investigate the link between traffic safety attitudes and road user behaviours, this study used a self-report measure of pedestrian behaviour, applying it in six countries; Bangladesh, China, Kenya, Thailand, the UK, and Vietnam. Focus was on the relationships between a respondent’s attitude towards risky or rule violating on-road behaviours (of other road users, or more generally, not specific to pedestrians), and the extent to which they reported performing three types of risky pedestrian behaviours (i.e., intentional rule violations, errors in judgement or memory, and aggressive behaviours). Data from a sample of 3,423 individuals was subjected to a series of regression models, revealing significant links between attitudes and pedestrian behaviours in all countries, in all three behavioural factors, after controlling for age, gender, and exposure to the road environment. Differences were found between countries in the strength of these relationships, with weaker connections between attitudes and behaviours in Kenya, and stronger connections in China (with other countries in-between the two). Results are discussed in terms of the need to understand the relationships between social cognitive constructs in the specific country in which a road safety intervention is intended to be implemented.     

Source recall enhances children's discrimination of seen and heard events

The effects of rehearsing actions by source (slideshow vs. story) and of test modality (picture vs. verbal) on source monitoring were examined. Seven- to 8-year-old children (N = 30) saw a slideshow event and heard a story about a similar event. One to 2 days later, they recalled the events by source (source recall), recalled the events without reference to source (no-source-cue recall), or engaged in no recall. Seven to 8 days later, all children received verbal and picture source-monitoring tests. Children in the source recall group were less likely than children in the other groups to claim they saw actions merely heard in the story. No-source-cue recall impaired source identification of story actions. The picture test enhanced recognition, but not source monitoring, of slide actions. Increasing the distinctiveness of the target events (Experiment 2) allowed the picture test to facilitate slideshow action discrimination by children in the no-recall group.     

Motivated self and recall: visual perspectives in remembering past behaviors

The present study examined motivational influences on visual perspectives in remembering past events and behaviors. Participants were first induced to believe that extraversion or introversion is conducive of success. Next, they recalled in details two introverted past behaviors. Introversion‐success participants, presumably motivated to see themselves as introverted, recalled and visualized the behaviors more from a first‐person actor perspective than did extraversion‐success participants (who recalled the behaviors from a third‐person observer perspective). Remembering past behaviors from a first‐person actor perspective implies that the behaviors are true of the self and impacts self‐definition to a relatively greater degree. The findings thus extend the influence of desired self to how people remember past events. They also contribute to the integration of motives in research on the link between self‐inferences and the subjective experience of remembering. Copyright © 2007 John Wiley & Sons, Ltd.     

Knowledge,probability, and credibility

This paper concerns study of the credibility of human sources of evidence and its relation to the inferential value of testimony they provide. From a certain view of 'knowledge' in epistemology comes the suggestion that credibility assessment can be construed as a cascaded inference in which attributes of human source credibility are identified. Scholarship from evidence law in jurisprudence suggests an evidential basis for credibility assessment in terms of these attributes. Applying Bayes' rule to this cascaded inference offers a way of expressing and combining credibility-related beliefs in the process of assessing the inferential value of evidence.     

Essentialist beliefs affect children's outgroup empathy,attitudes and prosocial behaviours in a setting of intergroup conflict

Empathy for salient outgroups can promote positive intergroup attitudes and prosocial behaviours. Less is known about which factors may promote empathy, particularly among children, in contexts of intergroup conflict. Empathy may depend on underlying cognitions, such as social essentialist beliefs, that is, believing that certain social categories have an underlying essence that causes members to share observable and non-observable properties. This study explored the influence of essentialist beliefs about ethno-religious categories on outgroup-directed empathy, attitudes and prosocial behaviours of children living in Northern Ireland (N = 88; M = 7.09, SD = 1.47 years old). Bootstrapped chain mediation found that lower essentialist beliefs predicted greater outgroup-directed empathy, which was positively related to outgroup attitudes, which in turn, predicted more outgroup prosocial behaviours. The findings highlight the importance of essentialist beliefs as an underlying factor promoting empathy, with links to prosocial behaviours in settings of intergroup conflict. The intervention implications are discussed.     

Free association,free recall,and stimulated recall compared

Three primary methods of recall (free association, free recall, stimulated recall) and two modifications of them (modified free association, modified stimulated recall) were defined by use of three variables: (a) presence or absence of prior laboratory training, (b) presence or absence of E controlled test stimulation, and (c) test instructions to free associate or to recall Data obtained from approximately 300 Ss and an earlier set of 600 revealed the differential effectiveness of all three primary methods in recall and misrecall.
