Breaking down unitization: Is the whole greater than the sum of its parts?

Memory impairments are often observed in aging. Specifically, older adults have difficulty binding together disparate elements (relational memory). We have recently shown that a cognitive strategy known as unitization can mitigate impaired relational learning in the transverse patterning task (TP) in both amnesia and healthy aging. This strategy allows items to be fused together through an interaction such that one item acts upon another. In the context of TP, unitization is comprised of three component processes: (1) fusion, (2) motion, and (3) semantic comprehension of action/consequence sequences. Here, we examine which of these components are sufficient to mitigate age-related impairments. Four groups of older adults were given either the full unitization strategy or one of the three component strategies. Each group of older adults showed impairments in memory for the relations among items under standard training instructions relative to a threshold that marks learning of a winner-take-all rule (elemental threshold). However, participants who were given either the full unitization strategy or the action/consequence-only strategy showed improved performance, which was maintained following the 1-hour delay. Therefore, semantically rich action/consequence interactions are sufficient to mitigate age-related relational memory impairments.     

Is the whole more than the sum of the parts? Re-evaluating social status in marketing

Data from 2 national surveys were examined to determine whether the components of social status (education, income, occupation) as separate individual factors could explain more variance than social status composites (Coleman, Hollingshead, Census). In general the evidence implies that the components are better predictors than the composite score, and that in the majority of cases only the raw education and income information is required for prediction.     

The whole is more than the sum of its parts – Audiovisual processing of phonemes investigated with ERPs

In the current ERP study, an active oddball task was carried out, testing pure tones and auditory, visual and audiovisual syllables. For pure tones, an MMN, an N2b, and a P3 were found, confirming traditional findings. Auditory syllables evoked an N2 and a P3. We found that the amplitude of the P3 depended on the distance between standard and deviant. A smaller distance required more attention, which was reflected in a larger amplitude. An analysis of audiovisual material, after correction for visual activity, showed that McGurk type stimuli evoked brain responses that differed from both the standard and the congruent deviants. Finally, we found that congruent audiovisual stimuli elicited an N2 with a shorter latency and a P3 with a smaller amplitude than auditory stimuli. The current ERP study, thus, shows that for audiovisual processing the whole is more than the sum of its parts.     

Whose idea is it anyway? The importance of reputation in acknowledgement

Six‐year‐old children negatively evaluate plagiarizers just as adults do (Olson & Shaw, 2011), but why do they dislike plagiarizers? Children may think plagiarism is wrong because plagiarizing negatively impacts other people's reputations. We investigated this possibility by having 6‐ to 9‐year‐old children evaluate people who shared their own or other people's ideas (stories). In Experiment 1, we found that children consider it acceptable to retell someone else's story if the source is given credit for their story (improving the source's reputation), but not if the reteller claims credit for the story (steals credit away from someone else). Experiments 2 and 3 showed that children do not consider it bad to lie by giving someone else credit for one's own good story (improving someone else's reputation), but do consider it bad to give someone else credit for one's own bad story (improving one's own reputation at the expense of someone else's). Experiment 4 demonstrated that children think it is equally bad to take credit for someone else's idea for oneself as it is to take someone else's idea and give credit to someone else, suggesting that children dislike when others take credit away from someone else, regardless of whether or not it improves the plagiarizer's reputation. Our results suggest that children dislike plagiarism because it negatively affects others' reputations by taking credit away from them.     

Attentional dysfunction, social perception, and social competence: what is the nature of the relationship?

The aim of this study was to examine the nature of the relationship between attentional dysfunction and social competence deficits in patients with schizophrenia. Attentional functioning, social perception, and social competence were assessed in 56 inpatients. Measures of vigilance and span of apprehension were administered to assess attentional functioning. Social perception was assessed with an audiovisual measure of affect recognition. Social competence was rated from a role-play task. Span of apprehension and auditory vigilance emerged as specific predictors of social competence. Affect recognition was tested as a mediator and a moderator of the relationship between attentional dysfunction and social competence. Affect recognition was found to moderate the relationship between span of apprehension and social competence.     

The debate over food biotechnology in the United States: is a societal consensus achievable?

Unless the public comes to agree that the benefits of food biotechnology are desirable and the associated risks are acceptable, our society may fail to realize much of the potential benefits. Three historical cases of major technological innovations whose benefits and risks were the subject of heated public controversy are examined, in search of lessons that may suggest a path toward consensus in the biotechnology debate. In each of the cases—water fluoridation, nuclear power and pesticides—proponents of the technology gathered scientific evidence that they believed established that the innovations were safe. In each case, the federal government was heavily involved in oversight, safety regulation, and in the first two cases, active promotion of the technology. Supporters of the technologies employed a variety of communications strategies, ranging from massive “educational” campaigns (e.g. “Our Friend The Atom”) to vituperative ad hominem attacks on leading opponents. None of these strategies succeeded in achieving broad societal acceptance of the technologies. Fluoridation today is opposed as vigorously by activist groups as it was when first introduced around 1950; it has not been universally adopted even in the U.S., and it has been rejected in most other countries. The American nuclear power industry is moribund, and the public has essentially rejected the technology. The pesticide industry is thriving, with new generations of products succeeding older more hazardous chemicals in a constant cycle. However, strong regulation has failed to prevent adverse health and ecological effects, which have been empirically associated with pesticide uses after the chemicals were dispersed in the environment. Debate over whether risks of such effects are acceptable has been heated for four decades, with scientists and the public divided. None of these cases offers an ideal model for the biotechnology revolution, though they do reveal many strategies that have not worked. The biotechnology debate is also taking place at a time when our concepts of risk communication have improved, and when many consumers are more actively concerned with buying products perceived to be less likely to harm the environment. Based on the three case histories and more recent trends, some characteristics of a process for seeking a societal consensus are described. They include explicitly defining the subjects for consensus; including all stakeholders in a respectful dialogue; confronting value issues, such as acceptability of risks and ethical perceptions; listening to others’ perspectives, and being willing to change one’s own point of view. If activists on all sides of the food biotechnology debate are willing to commit to such a consensus-building process, there is hope that the U.S. national debate can be resolved in a manner satisfactory to essentially all parties.     

Do the importance of influencer- and customer-generated content on social media affect willingness to pay more for potential customers?

The number of social media platforms and users have reached significant amounts. Users can interact with millions of other users by sharing their experiences and evaluations concerning the product/service they purchased on social media. This social media sharing can hence affect the purchasing decision processes of potential customers who are searching for information. Moreover, sharing from different sources such as influencers and customers may create differences in the importance the potential consumer attaches to the shared content. Since there is there is a gap in the existing literature, there is a need to explore these relationships. Consequently, we examined the relationship between information quality, willingness to pay more (WPM), source credibility, the importance attached to participant sharing (IPS), and the importance attached to non-participant sharing (INPS). A questionnaire designed to test this relationship was administered to 323 participants; the obtained data was then analyzed using partial least squares path modeling. According to the analysis results, we noted the emergence of a positive association of information quality with INPS and IPS (posts by both customers and influencers). In contrast, we discovered a relationship of source credibility with INPS (posts by both customers and influencers) and IPS (posts by influencers). In addition, the positive association of INPS (posts by both customers and influencers) and WPM was confirmed. These main findings indicate that e-commerce companies should persuade and encourage their customers and influencers to post from their profiles.     

Inhibition of return in visual marking? The importance of the interstimulus interval and the type of search task

Four experiments are presented that examine the possibility that inhibition of return (IOR) may occur in visual marking. Previously, Watson and Humphreys (1997), using a cue duration of 750 ms and an interstimulus interval (ISI) of 250 ms, concluded that IOR was not present in visual marking. In the present study, the first experiment examined three ISIs (250 ms, 500 ms, and 750 ms) with a constant stimulus onset asynchrony (SOA, 1000 ms) in a typical cueing paradigm and failed to find IOR with the short ISI. Based on these findings, the second (feature search) and third (conjunction search) experiments tested for IOR by using a visual marking paradigm with a 500 ms ISI. Evidence for IOR was found in the feature search (preview condition similar to half-elements baseline condition) and not in the conjunction search (preview condition similar to the all-elements baseline). The typical preview effect was found in Experiment 4 with a cue duration 1000 ms and no ISI. Overall, these findings indicate that IOR may play a role in visual marking, but only with feature search tasks and long ISIs between displays.     

The Inner Game of Sport: is Everything in the Brain?

The article deals with the following: (1) Three brain imaging studies on athletes are evaluated. What do these neuroscientific studies tell us about the brain and mind of the athlete? (2) Empirical investigations will need a neuro-theory of mind if they are to make the leap from neural activity to the mental. The article looks at such a theory, Gerald Edelman's ‘Neural Darwinism’. What are the implications of such a theory for sport science and philosophy of sport? (3) The article appreciates some of the neurosciences applications, but questions the hope of giving a complete theory of mind.     

The cognitive interview: is its benefit affected by the level of witness emotion?

This research investigated whether a witness's emotion could influence the accuracy of statements obtained by the use of a cognitive interview. A total of 70 first-year university students viewed a video depicting a road accident. Electrodes were attached to their arms in order to send fictitious electric shocks during the video (high-arousal condition) or to measure physiological signs (low-arousal condition). One week later, they were interviewed using either a cognitive interview (CI) or a structured interview (SI). It was hypothesised that the beneficial effect of the cognitive interview would be amplified by a high level of arousal, particularly concerning central aspects of the video. Results indicated that a CI elicited more correct central and peripheral details recalled, whatever the level of arousal inducted during the encoding of the to-be remembered event. Furthermore, high-arousal participants produced more accurate testimonies concerning peripheral details than participants exposed to a low level of arousal. No interaction between interview and emotion was found. The theoretical and practical implications for interviewing witnesses are described.     

What's the difference? Insider perspectives on the importance,content, and meaning of interpersonal differences

This study presents a new approach to examine how team members experience interpersonal differences. This approach offers a way to examine how team members experience their differences with specific other individuals, and how these differences are related to the amount of perceived conflict with these individuals in an organizational context. Data from a non‐profit governmental institution in The Netherlands were analysed, including 80 participants from 15 diverse teams. Five types of differences were salient to the individuals in this sample: differences related to extraversion; work pose; approach to work; task‐related expertise; and seniority. Furthermore, individuals tend to contrast positive and negative evaluations of differences related to extraversion and approaches to work, but to conceptualize positive and negative evaluations of task‐related expertise, seniority, and work pose as more mutually independent phenomena. Moreover, we found that differences related to task‐related expertise were negatively related to both task and relationship conflict. In contrast, differences related to extraversion were positively related to both task and relationship conflict. Finally, the approach‐to‐work cluster was positively related to only task conflict.     

Learning to cheat: The interaction of moral‐development and social learning theories

A possible interaction between moral‐development levels and social learning variables is tested with self‐report data on test cheating from 175 college students. Among those at lower developmental levels, peer reactions best explain cheating behavior. For those at middle development levels, internalized definitions are most explanatory. Among those with more autonomous moralities, no pattern of social variables emerges to explain cheating.     

Destination memory in social interaction: better memory for older than for younger destinations in normal aging?

Destination memory, a memory component allowing the attribution of information to its appropriate receiver (e.g., to whom did I lend my pen?), is compromised in normal aging. The present paper investigated whether older adults might show better memory for older destinations than for younger destinations. This hypothesis is based on empirical research showing better memory for older faces than for younger faces in older adults. Forty-one older adults and 44 younger adults were asked to tell proverbs to older and younger destinations (i.e., coloured faces). On a later recognition test, participants had to decide whether they had previously told some proverb to an older/younger destination or not. Prior to this task, participants reported their frequency of contact with other-age groups. The results showed lower destination memory in older adults than in younger adults. Interestingly, older adults displayed better memory for older than for younger destinations. The opposite pattern was seen in younger adults. The low memory for younger destinations, as observed in older adults, was significantly correlated with limited exposure to younger individuals. These findings suggest that for older adults, the social experience can play a crucial role in the destination memory, at least as far as exposure to other-age groups is concerned.     

Children's friendships and learning in school: Cognitive enhancement through social interaction?

Background. Recent literature has identified that children's performance on cognitive (or problem‐solving) tasks can be enhanced when undertaken as a joint activity among pairs of pupils. Performance on this ‘social’ activity will require quality relationships between pupils, leading some researchers to argue that friendships are characterized by these quality relationships and, therefore, that friendship grouping should be used more frequently within classrooms. Aims. Children's friendship grouping may appear to be a reasonable basis for cognitive development in classrooms, although there is only inconsistent evidence to support this argument. The inconsistency may be explained by the various bases for friendship, and how friendship is affected by cultural contexts of gender and schooling. This study questions whether classroom‐based friendship pairings will perform consistently better on a cognitive task than acquaintance pairings, taking into account gender, age, and ability level of children. The study also explores the nature of school‐based friendship described by young children. Sample. 72 children were paired to undertake science reasoning tasks (SRTs). Pairings represented friendship (versus acquaintance), sex (male and female pairings), ability (teacher‐assessed high, medium, and low), and age (children in Years 1, 3, and 5 in a primary school). Method. A small‐scale quasi‐experimental design was used to assess (friendship‐ or acquaintance‐based) paired performance on SRTs. Friendship pairs were later interviewed about qualities and activities that characterized their friendships. Results. Girls' friendship pairings were found to perform at the highest SRT levels and boys' friendship pairing performed at the lowest levels. Both boy and girl acquaintance pairings performed at mid‐SRT levels. These findings were consistent across Year (in school) levels and ability levels. Interviews revealed that male and female friendship pairs were likely to participate in different types of activity, with girls being school‐inclusive and boys being school‐exclusive. Conclusion. Recommendations to use friendship as a basis for classroom grouping for cognitive tasks may facilitate performance of some pairings, but may also inhibit the performance of others. This is shown very clearly with regard to gender. Some of the difference in cognitive task performance may be explained by distinct, cultural (and social capital) orientations to friendship activities, with girls integrating school and educational considerations into friendship, and boys excluding school and educational considerations.     

‘No Man is an Island’: Effects of social seclusion on social dream content and REM sleep

Based on the Social Simulation Theory of dreaming (SST), we studied the effects of voluntary social seclusion on dream content and sleep structure. Specifically, we studied the Compensation Hypothesis, which predicts social dream contents to increase during social seclusion, the Sociality Bias – a ratio between dream and wake interactions – and the Strengthening Hypothesis, which predicts an increase in familiar dream characters during seclusion. Additionally, we assessed changes in the proportion of REM sleep. Sleep data and dream reports from 18 participants were collected preceding (n = 94), during (n = 90) and after (n = 119) a seclusion retreat. Data were analysed using linear mixed-effects models. We failed to support the Compensation Hypothesis, with dreams evidencing fewer social interactions during seclusion. The Strengthening Hypothesis was supported, with more familiar characters present in seclusion dreams. Dream social interactions maintained the Sociality Bias even under seclusion. Additionally, REM sleep increased during seclusion, coinciding with previous literature and tentatively supporting the proposed attachment function for social REM sleep.     

The “false consensus effect”: An egocentric bias in social perception and attribution processes

Evidence from four studies demonstrates that social observers tend to perceive a “false consensus” with respect to the relative commonness of their own responses. A related bias was shown to exist in the observers' social inferences. Thus, raters estimated particular responses to be relatively common and relatively unrevealing concerning the actors' distinguishing personal dispositions when the responses in question were similar to the raters' own responses; responses differing from those of the rater, by contrast, were perceived to be relatively uncommon and revealing of the actor. These results were obtained both in questionnaire studies presenting subjects with hypothetical situations and choices and in authentic conflict situations. The implications of these findings for our understanding of social perception phenomena and for our analysis of the divergent perceptions of actors and observers are discussed. Finally, cognitive and perceptual mechanisms are proposed which might account for distortions in perceived consensus and for corresponding biases in social inference and attributional processes.
