Blushing after a moral transgression in a prisoner's dilemma game: appeasing or revealing?

This study investigated the alleged remedial effects of blushing in the context of real‐time interactions. Therefore, 30 pairs of prosocial individuals participated in a prisoner's dilemma ‘game’. The experiment was framed as an objective test of moral behaviour. To elicit a shameful moral transgression, one individual of each pair was instructed to select the non‐habitual cheat‐option on a pre‐defined target trial. Supporting the idea that violation of shared rules elicits blushing, the defectors displayed a blush on the target trial. Yet, unexpectedly, there was a negative relationship between the observed blush intensity and the trustworthiness attributed to the defectors. One explanation might be that the ‘victims’ used the blush response to deduce and interpret the defector's motive. As the antecedent behaviour involved in the present context was not completely unambiguous with respect to the perpetrators' motive (e.g. innocent playing around vs. maximizing outcomes) the observers might have interpreted blushing as signaling that the situation should be interpreted as an intentional violation of a social standard. Together the available evidence suggests that only in the context of unambiguous antecedent behaviours blushing has remedial effects, whereas in ambiguous situations blushing has undesirable revealing effects.

Defection in the dark? A randomized‐response investigation of cooperativeness in social dilemma games

As previous research has demonstrated numerous times, humans show a robust tendency for cooperation. However, part—or indeed all—of this cooperativeness may be due to socially desirable responding. To address this problem, we propose and apply a new approach for the unbiased measurement of cooperativeness in social dilemma games. Specifically, we employ an extension of the randomized‐response technique (RRT). The RRT protects the privacy of respondents by adding random noise to their responses. It thus encourages more honest responding and thereby provides less biased estimates of sensitive attributes. In a large‐scale study with 2043 respondents we maximized anonymity in a one‐shot prisoner's dilemma game through use of the RRT. Comparing the prevalence rates for cooperation obtained via the RRT with those from direct self‐report showed that traditional direct questioning formats overestimate cooperation rates, with a relative bias of 18%. This finding suggests that to a considerable extent, self‐reported cooperation is due to socially desirable responding, rather than actual cooperativeness. However, our results also demonstrate that cooperation remains substantial even under conditions of maximized anonymity. Copyright © 2011 John Wiley & Sons, Ltd.     

Alexithymia in the interpersonal domain: A general deficit of empathy?

Alexithymia and empathy have been related but very little is known on shared variance between their respective affective and cognitive dimensions. We examined this question with correlations, as well as both exploratory and confirmatory analyses, and controlled for anxiety and depression. The responses of 645 young adults to self-report questionnaires of alexithymia (TAS-20), empathy (IRI), anxiety (STAI-T) and depression (BDI-13) were examined. We observed associations between the proposed cognitive components of alexithymia (externally-oriented thinking) and that of empathy (perspective taking, fantasy) as well as empathic concern, which were insensitive to anxiety or depression. In contrast, associations between the proposed affective components of alexithymia (difficulty identifying feelings, difficulty describing feelings) and empathy (personal distress) were largely due to shared covariance with anxiety. A model encompassing an affective and a cognitive (including empathic concern) latent factors emerged, even after controlling for dysphoric affects. These findings suggest specific associations between cognitive and affective components of both constructs that were dissimilarly affected by anxiety and depression. The allocation of empathic concern to the cognitive factor is also discussed.     

Infant feeding and HIV in Sub-Saharan Africa: what lies beneath the dilemma?

The debate over how to best guide HIV-infected mothers in resource-poor settings on infant feeding is more than two decades old. Globally, breastfeeding is responsible for approximately 300,000 HIV infections per year, while at the same time, UNICEF estimates that not breastfeeding (formula feeding with contaminated water) is responsible for 1.5 million child deaths per year. The largest burden of these infections and deaths occur in Sub-Saharan Africa. Using this region as an example of the burden faced more generally in other resource-poor settings, we contrast the evolution of the clinical standard of care for infant feeding with HIV-infected mothers in high-income countries to the current international clinical guidelines for HIV-infected mothers and infant feeding in resource-poor settings. While the international guidelines of exclusive breastfeeding for a 6-month period seem to offer the least-worst strategy for reducing mother-to-child transmission of HIV during infancy while conferring some immunity through breastfeeding post-6 months, we argue that the impact of the policy on mothers and healthcare workers on the ground is not well understood. The harm reduction approach on the level of health policy translates into a complicated, painful moral dilemma for HIV-positive mothers and those offering them guidance on infant feeding. We argue that the underlying socio-economic disparities that continue to fuel the need for a harm reduction policy on infant feeding and the harm to women and children justify: (1) that higher priority be given to solving the infant feeding dilemma with improved data on safe feeding alternatives, and (2) support of innovative, community-driven solutions that address the particular economic and cultural challenges that continue to result in HIV-transmission to children within these communities.

Rigidity of the far‐right? Motivated social cognition in a nationally representative sample of Hungarians on the eve of the far‐right breakthrough in the 2010 elections

We investigated the “rigidity of the right” hypothesis in the context of the far‐right breakthrough in the 2010 Hungarian parliamentary elections. This hypothesis suggests that psychological characteristics having to do with need for security and certainty attract people to a broad‐based right‐wing ideology. A nationally representative sample (N = 1000) in terms of age, gender and place of residence was collected by means of the random walking method and face‐to‐face interviews. Voters of JOBBIK (n = 124), the radically nationalist conservative far‐right party, scored lower on System Justifying Belief, Belief in a Just World (Global) and higher on Need for Cognition than other voters. Our results contradict the “rigidity of the right” hypothesis: JOBBIK voters scored, on many measures, opposite to what the hypothesis would predict.     

Constrained maximization reconsidered — An elaboration and critique of Gauthier's modelling of rational cooperation in a single prisoner's dilemma

Gauthier's argument for constrained maximization, presented inMorals by Agreement, is perfected by taking into account the possibility of accidental exploitation and discussing the limitations on the values of the parameters which measure the translucency of the actors. Gauthier's argument is nevertheless shown to be defective concerning the rationality of constrained maximization as a strategic choice. It can be argued that it applies only to a single actor entering a population of individuals who are themselves not rational actors but simple rule-followers. A proper analysis of the strategic choice situation involving two rational actors who confront each other shows that constrained maximization as the choice of both actors can only result under very demanding assumptions.     

Family decision at the turn of the century: has the changing structure of households impacted the family decision‐making process?

Evaluation of husbands' and wives' influence in family decision making is heavily reliant on studies conducted in the 1970s and 1980s. Since that time, profound changes have occurred in the American family. These changes may have affected the nature of decision making in the household. To examine the degree to which earlier findings are still generalisable today, hypotheses are developed and tested with a contemporary sample of 458 men and women. Results suggest that there have been significant changes in the roles assumed in the family decision‐making process, with the wife gaining more influence in all decision areas. The results indicate that marketers must re‐examine their marketing strategies for some products and/or services. Possible theoretical explanations are suggested to explain why these changes may have occurred. Copyright © 2002 Henry Stewart Publications.     

Impact of induced joy on literacy in children: does the nature of the task make a difference?

This research examined whether induced joy influences fifth graders’ performance in literacy tasks. Children were asked to recall a joyful experience, used as a joy induction, before completing either a grammar (Study 1) or textual comprehension task (Study 2). The grammar task involved understanding at the surface level and retrieval of appropriate declarative and procedural knowledge, but limited elaboration unlike the textual comprehension task, which tackled inference generation. By differentiating tasks based on depth of processing required for completion we aimed at testing the validity of two concurrent hypotheses: that of a facilitating effect and that of a detrimental effect of induced joy. Compared to controls, joy induced children showed better performance on the grammar task – specifically children with lower language ability. No differences across groups emerged as a function of joy induction on the text comprehension task. Results are discussed with respect to emotion effects on cognition.     

Becoming a high‐fidelity – super – imitator: what are the contributions of social and individual learning?

In contrast to other primates, human children's imitation performance goes from low to high fidelity soon after infancy. Are such changes associated with the development of other forms of learning? We addressed this question by testing 215 children (26–59 months) on two social conditions (imitation, emulation) – involving a demonstration – and two asocial conditions (trial‐and‐error, recall) – involving individual learning – using two touchscreen tasks. The tasks required responding to either three different pictures in a specific picture order (Cognitive: Airplane→Ball→Cow) or three identical pictures in a specific spatial order (Motor‐Spatial: Up→Down→Right). There were age‐related improvements across all conditions and imitation, emulation and recall performance were significantly better than trial‐and‐error learning. Generalized linear models demonstrated that motor‐spatial imitation fidelity was associated with age and motor‐spatial emulation performance, but cognitive imitation fidelity was only associated with age. While this study provides evidence for multiple imitation mechanisms, the development of one of those mechanisms – motor‐spatial imitation – may be bootstrapped by the development of another social learning skill – motor‐spatial emulation. Together, these findings provide important clues about the development of imitation, which is arguably a distinctive feature of the human species.     

A Meta‐Analytic Investigation of the Within‐Person Self‐Efficacy Domain: Is Self‐Efficacy a Product of Past Performance or a Driver of Future Performance?

We conducted a meta‐analysis to determine whether the within‐person self‐efficacy/performance relationship is positive, negative, or null and to compare the strength of the self‐efficacy/performance and past performance/self‐efficacy within‐person relationships. The self‐efficacy/performance within‐person corrected correlation was .23 but was weak and nonsignificant (ρ = .06) when controlling for the linear trajectory, revealing that the main effect was spurious. The past performance/self‐efficacy within‐person corrected correlation was .40 and remained positive and significant (ρ = .30) when controlling for the linear trajectory. The moderator results revealed that at the within‐person level of analysis: (a) self‐efficacy had at best a moderate, positive effect on performance and a null effect under other moderating conditions (ρ ranged from –.02 to .33); (b) the main effect of past performance on self‐efficacy was stronger than the effect of self‐efficacy on performance, even in the moderating conditions that produced the strongest self‐efficacy/performance relationship; (c) the effect of past performance on self‐efficacy ranged from moderate to strong across moderating conditions and was statistically significant across performance tasks, contextual factors, and methodological moderators (ρ ranged from .18 to .52). Overall, this suggests that self‐efficacy is primarily a product of past performance rather than the driving force affecting future performance.     

Lipreading in the prelingually deaf: what makes a skilled speechreader?

Lipreading proficiency was investigated in a group of hearing-impaired people, all of them knowing Spanish Sign Language (SSL). The aim of this study was to establish the relationships between lipreading and some other variables (gender, intelligence, audiological variables, participants' education, parents' education, communication practices, intelligibility, use of SSL). The 32 participants were between 14 and 47 years of age. They all had sensorineural hearing losses (from severe to profound). The lipreading procedures comprised identification of words in isolation. The words selected for presentation in isolation were spoken by the same talker. Identification of words required participants to select their responses from set of four pictures appropriately labelled. Lipreading was significantly correlated with intelligence and intelligibility. Multiple regression analyses were used to obtain a prediction equation for the lipreading measures. As a result of this procedure, it is concluded that proficient deaf lipreaders are more intelligent and their oral speech was more comprehensible for others.     

Orientation specificity in spatial memory: what makes a path different from a map of the path?

Three studies investigated the factors that lead spatial information to be stored in an orientation-specific versus orientation-free manner. In Experiment 1, we replicated the findings of Presson and Hazelrigg (1984) that learning paths from a small map versus learning the paths directly from viewing a world leads to different functional characteristics of spatial memory. Whether the route display was presented as the path itself or as a large map of the path did not affect how the information was stored. In Experiment 2, we examined the effects of size of stimulus display, size of world, and scale transformations on how spatial information in maps is stored and available for use in later judgments. In Experiment 3, we examined the effect of size on the orientation specificity of the spatial coding of paths that are viewed directly. The major determinant of whether spatial information was stored and used in an orientation-specific or an orientation-free manner was the size of the display. Small displays were coded in an orientation-specific way, whereas very large displays were coded in a more orientation-free manner. These data support the view that there are distinct spatial representations, one more perceptual and episodic and one more integrated and model-like, that have developed to meet different demands faced by mobile organisms.     

Personality Change in the Oldest‐Old: Is It a Matter of Compromised Health and Functioning?

The present longitudinal study investigates continuity and change in the personality dimensions of extraversion and neuroticism among the oldest‐old. Overall disease load, self‐rated health, functional capacity, impaired vision and hearing, self‐reported cognitive impairment, and measured cognitive status were tested for their role as potentially relevant late‐life predictors of personality change. The sample consists of 408 individuals aged 80–98 in the Swedish OCTO‐Twin Study who completed the Eysenck Personality Inventory at four measurement occasions during a 6‐year period. Growth curve analyses revealed an age‐related linear decrease in extraversion and stability in neuroticism. More extraverted individuals were more educated and perceived their health and cognition as better. Notably, only hearing impairment was found to be related to a steeper age‐related decline in extraversion. A life span developmental model focusing on health‐related changes can improve our understanding of personality change in late life.     

Which empathy? Limitations in the mirrored “understanding” of emotion

The recent discovery of so-called “mirror-neurons” in monkeys and a corresponding mirroring “system” in humans has provoked wide endorsement of the claim that humans understand a variety of observed actions, somatic sensations, and emotions via a kind of direct representation of those actions, sensations, and emotions. Philosophical efforts to assess the import of such “mirrored understanding” have typically focused on how that understanding might be brought to bear on theories of mindreading (how we represent other creatures as having mental states), and usually in cases of action. By contrast, this paper assesses mirrored understanding in cases of emotion and its import for theories of empathy and especially empathy in ethical contexts. In particular, this paper argues that the mirrored understanding claim is ambiguous and ultimately misleading when applied to emotion, partly because mirroring proponents fail to appreciate the way in which empathy might serve a distinct normative function in our judgments of what other people feel. The paper thus concludes with a call to revise the mirrored understanding claim, whether in neuroscience, psychology, or philosophy.     

Disorganized families and the helping professions: ‘who's in charge of what?’

Disorganized families fail to define their executive and caretaking structure, resulting in multiple social and emotional problems. They tend to be referred to a Child and Family Psychiatric Clinic in crisis and with a wide network of professional workers already involved. The professionals' rôle often can be seen as 'supplementing' apparent functional deficiencies in the family. Work with disorganized families can be very demanding on professional time and emotional energy but is facilitated by everyone knowing 'who's in charge of what' decisions in the family's professional network. A case is presented to suggest that the Clinic's initial aim should be to clarify the responsibilities and role of each member of the professional network, and then of the structure and organization in the family. Joint family-professional network meetings can help to achieve these aims.     

How different is a 3D‐printed replica from a conspecific in the eyes of a zebrafish?

Robotics is emerging as a promising tool for aiding research on animal behavior. The possibility of generating customizable, controllable, and standardized robotic stimuli has been demonstrated through a number of behavioral assays, involving vertebrates and invertebrates. However, the specific appraisal of the nature of robotic stimuli is currently lacking. Here, we attempt to evaluate this aspect in zebrafish, through a within‐subject design in which experimental subjects are faced with three experimental conditions. In the first test, we investigated sociability by measuring zebrafish response to a conspecific separated by a one‐way glass. In the second test, we studied zebrafish behavior in response to a 3D‐printed zebrafish replica actuated along realistic trajectories through a novel four‐degree‐of‐freedom robotic platform. Last, we investigated fear responses in a shelter‐seeking test. In agreement with our expectations, zebrafish exhibited an equivalent preference for live and robotic stimuli, and the degree of preference for the robotic replica correlated negatively with the individual propensity to seek shelter. The equivalent preference for the replica and conspecific suggests that the appraisal of the target stimuli is analogous. The preliminary evidence of a correlation between behavioral responses across tests points to the readability of robotics‐based approaches to investigate interindividual differences.     

How strong is the comparison‐to‐the‐strongest heuristic?: An empirical test of the comparison‐ to‐the‐strongest heuristic in probability judgment1,2

Abstract: Windschitl and Wells (1998 ) proposed that the pairwise comparison between the focal and strongest alternative outcomes plays an important role in probability judgment. However, their studies did not control the effects of alternative outcomes other than the strongest one. This article tested whether only the strongest alternative outcome would affect probability judgment, using a variable selection method in a multiple regression analysis. Study 1 reanalyzed the results of Windschitl and Young (2001 ) and showed that only the strongest alternative outcome affects probability judgment. In Study 2, a new experiment was conducted to modify the methodological problems in Study 1. The results of Study 2 were identical to those of Study 1. All these results consistently supported the comparison hypothesis.
