On blame-freeness and reciprocity: an experimental study

The theory of reciprocity is predicated on the assumption that people are willing to reward nice or kind acts and to punish unkind ones. This assumption raises the question as to how to define kindness. In this paper we offer a new definition of kindness that we call “blame-freeness.” Put most simply, blame-freeness states that in judging whether player i has been kind or unkind to player j in a social situation, player j would have to put himself in the strategic position of player i, while retaining his preferences, and ask if he would have acted in a manner that was worse than i did under identical circumstances. If j would have acted in a more unkind manner than i acted, then we say that j does not blame i for his behavior. If, however, j would have been nicer than i was, then we say that “j blames i” for his actions (i’s actions were blameworthy). We consider this notion a natural, intuitive and empirically relevant way to explain the motives of people engaged in reciprocal behavior. After developing the conceptual framework, we then test this concept in a laboratory experiment involving tournaments and find significant support for the theory.

''Rainbow Designer'' : for global and multicultural design

What do the designers tend to achieve? To relate themselves to the reality by producing visual registers of emotions and thoughts, or by projecting and producing objects that are functional, adapting technologies to daily needs. That requires that a designer be a keen observer of his physical surroundings and have a fine sensibility to cultures, enabling him to disassemble the latent forms of the reality and cultural symbolisms in order to perceive the order underlying them and the principles of their composition and unity. Only then could he reproduce the nature and respond to cultural callings. In this process of understanding the surrounding reality of nature and cultures, a designer always moves, generally without being aware of it, between two processes: identity search and self-identification.

À procura da identidade de Heinz : um modelo de compreensão da motivação moral

RESUMO: As teorias psicológicas da moralidade dividem-se na conceptualização da motivação moral, o tema desta dissertação. Os modelos construtivistas, apoiados na epistemologia genética, privilegiam a cognição como factor determinante mas, as teorias que enfatizam o funcionamento individual admitem que as emoções e a identidade interferem na tendência de cada pessoa agir moralmente. Particularmente apoiados na segunda perspectiva, testámos um modelo preditor da motivação moral com três variáveis, identidade, identidade moral e integridade, todas avaliadas por medidas psicométricas, em duas amostras. A primeira era composta por 320 estudantes do 12º ano de uma escola do concelho de Lisboa, com idades compreendidas entre 18 e 20 anos (M=18,22; Dp=0,49), 108 masculinos e 194 femininos e a segunda era composta por 174 sujeitos, estudantes finalistas de cursos profissionais de uma escola do concelho de Lisboa frequentada por alunos provenientes de ambientes sociais caracterizados pelo stresse sócio-económico e familiar, e até, em bastantes casos, que já tinham participado em actos ilegais relacionados com furto, vandalismo, tráfico de drogas, e agressões, com idades compreendidas entre 18 e 22 anos (M=18,98; Dp=1,075), 104 masculinos e 70 femininos. A primeira amostra foi considerada normativa e a segunda de risco psicossocial. Para avaliar a motivação moral foi construída uma medida que incluiu dois aspectos: a consciência moral, relativa à avaliação objectiva e subjectiva que os indivíduos fazem das situações morais que através de processos de análise de conteúdo foi distinguida em três categorias exclusivas: não transgressão, transgressão relativizada e transgressão; e a autoatribuição de emoções que indica a probabilidade objectiva dos indivíduos cometerem acções morais. Foi verificada a existência de diferenças individuais em ambas as medidas da motivação moral e, também, a existência de diferenças na atribuição de emoções em função da consciência moral: os sujeitos da categoria transgressão apresentaram atribuições mais negativas do que os sujeitos de transgressão relativizada e estes, por sua vez, apresentaram atribuições mais negativas que os sujeitos da categoria não transgressão. Estes resultados confirmam o papel da identidade na motivação moral. A análise da predição confirmou que a integridade, a identidade e a identidade moral, em ordem decrescente de capacidade explicativa, constituem factores preditores tanto da consciência moral como da auto-atribuição de emoções. ABSTRACT: Moral motivation, the subject of this thesis, is differently viewed by several psychological perspectives. Constructivist models supported by genetic epistemology define cognition as the determinant factor while theories that emphasize individual functioning admit that emotions and identity have a central role in the way that persons could morally act. Particularly supported in this second approach we tested a predictive model of moral motivation with three variables, identity, moral identity and integrity, all evaluated by psychometric scales, in two samples. The first sample had 320 graduate high school students with age between 18 and 20 (M=18,22; SD=0,49), 108 male and 194 female and the second sample had 174 graduate students of vocational courses in high school of a risk social and familiar environment, many of them had already done illegal acts such as stealing, vandalism, drug traffic and aggressions; they had ages between 18 and 22 (M=18,98; SD=1,08), 104 male and 70 female. The first sample was considered normative and the second one was classified as psychosocial risk. To evaluate moral motivation we developed a measure that assesses two aspects: moral conscience, who includes both objective and subjective evaluation of moral situations that was distinguished in three exclusive categories by procedures of content analysis: non-transgression, justifiable transgression and transgression; and self-attribution of emotion that indicates the likelihood of committing moral actions. We observed individual differences in both measurements of moral motivation and also verified differences in emotional attribution on the basis of moral conscience: the individuals of transgression category presented more negative attributions than those of justifiable transgression and in turn the latter presented more negative attributions than individuals of non-transgression category. These results confirm the role of identity in moral motivation. The predictor analysis confirmed integrity, identity and moral identity, in descending order of explanatory power, as predictive variables of moral consciousness and self-attribution of emotions.

A identidade moral e a integridade são preditoras da motivação moral?

Com o objetivo de analisar os componentes que induzem o comportamento moral, apoiámo-nos nas teorias psicológicas que admitem a importância do papel das emoções e da identidade na motivação para a ação moral, contrariamente ao que era defendido pelas teorias construtivistas, que apenas referiam a cognição como motor do funcionamento moral. Deste modo elegemos a identidade moral e a integridade como variáveis que podem estar associadas à motivação moral. Participaram 91 adultos emergentes, com idades compreendidas entre os 18 e os 25 anos (M = 20,63; Dp = 2,33), 14 do género masculino e 77 do género feminino. Para avaliar a motivação moral, a identidade moral e a integridade utilizámos respetivamente a PMAM, EIM e EI. Os objetivos foram verificar se existem diferenças individuais na consciência moral e nas emoções atribuídas a atos de transgressão, se a intensidade das emoções auto-atribuídas varia em função da consciência moral, e se a identidade moral e a integridade estão associadas à motivação moral. Os resultados mostram que existem diferenças individuais tanto na consciência moral como na atribuição de emoções. Os sujeitos avaliaram as transgressões de cuidado, não cuidar de parente e infidelidade, com emoções mais negativas e com maior utilização de consciência moral de transgressão, do que as transgressões anti-sociais, fraude e mentira. Verificámos também que a intensidade emocional varia em função da consciência moral. As categorias de Transgressão Identitária e Transgressão estão associadas com emoções mais negativas e as de Transgressão Relativizada e Não Transgressão estão relacionadas com emoções menos negativas. Foi ainda encontrada associação entre a identidade moral e integridade com a motivação moral, mas apenas para as transgressões anti-sociais.

Analytical and compositional aspects of isoflavones in food and their biological effects

This paper provides an overview of analytical techniques used to determine isoflavones (IFs) in foods and biological fluids with main emphasis on sample preparation methods. Factors influencing the content of IFs in food including processing and natural variability are summarized and an insight into IF databases is given. Comparisons of dietary intake of IFs in Asian and Western populations, in special subgroups like vegetarians, vegans, and infants are made and our knowledge on their absorption, distribution, metabolism, and excretion by the human body is presented. The influences of the gut microflora, age, gender, background diet, food matrix, and the chemical nature of the IFs on the metabolism of IFs are described. Potential mechanisms by which IFs may exert their actions are reviewed, and genetic polymorphism as determinants of biological response to soy IFs is discussed. The effects of IFs on a range of health outcomes including atherosclerosis, breast, intestinal, and prostate cancers, menopausal symptoms, bone health, and cognition are reviewed on the basis of the available in vitro, in vivo animal and human data.

Age and flexible thinking: an experimental demonstration of the beneficial effects of increased cognitively stimulating activity on fluid intelligence in healthy older adults

The disuse hypothesis of cognitive aging attributes decrements in fluid intelligence in older adults to reduced cognitively stimulating activity. This study experimentally tested the hypothesis that a period of increased mentally stimulating activities thus would enhance older adults' fluid intelligence performance. Participants (N = 44, mean age 67.82) were administered pre- and post-test measures, including the fluid intelligence measure, Cattell's Culture Fair (CCF) test. Experimental participants engaged in diverse, novel, mentally stimulating activities for 10-12 weeks and were compared to a control condition. Results supported the hypothesis; the experimental group showed greater pre- to post-CCF gain than did controls (effect size d = 0.56), with a similar gain on a spatial-perceptual task (WAIS-R Blocks). Even brief periods of increased cognitive stimulation can improve older adults' problem solving and flexible thinking.

The effect of Parkinson's disease on time estimation as a function of stimulus duration range and modality

The present research sought to investigate the role of the basal ganglia in timing of sub- and supra-second intervals via an examination of the ability of people with Parkinson's disease (PD) to make temporal judgments in two ranges, 100-500 ms, and 1-5 s. Eighteen nondemented medicated patients with PD were compared with 14 matched controls on a duration-bisection task in which participants were required to discriminate auditory and visual signal durations within each time range. Results showed that patients with PD exhibited more variable duration judgments across both signal modality and duration range than controls, although closer analyses confirmed a timing deficit in the longer duration range only. The findings presented here suggest the bisection procedure may be a useful tool in identifying timing impairments in PD and, more generally, reaffirm the hypothesised role of the basal ganglia in temporal perception at the level of the attentionally mediated internal clock as well as memory retrieval and/or decision-making processes.

The psychological, neurochemical and functional neuroanatomical mediators of the effects of positive and negative mood on executive functions

In this review we evaluate the cognitive and neural effects of positive and negative mood on executive function. Mild manipulations of negative mood appear to have little effect on cognitive control processes, whereas positive mood impairs aspects of updating, planning and switching. These cognitive effects may be linked to neurochemistry: with positive mood effects mediated by dopamine while negative mood effects may be mediated by serotonin levels. Current evidence on the effects of mood on regional brain activity during executive functions, indicates that the prefrontal cortex is a recurrent site of integration between mood and cognition. We conclude that there is a disparity between the importance of this topic and awareness of how mood affects, executive functions in the brain. Most behavioural and neuroimaging studies of executive function in normal samples do not explore the potential role of variations in mood, yet the evidence we outline indicates that even mild fluctuations in mood can have a significant influence on neural activation and cognition.

The BOLD response during Stroop task-like inhibition paradigms: effects of task difficulty and task-relevant modality

Previous studies of the Stroop task propose two key mediators: the prefrontal and cingulate cortices but hints exist of functional specialization within these regions. This study aimed to examine the effect of task modality upon the prefrontal and cingulate response by examining the response to colour, number, and shape Stroop tasks whilst BOLD fMRI images were acquired on a Siemens 3 T MRI scanner. Behavioural analyses indicated facilitation and interference effects and a noticeable effect of task difficulty. Some modular effects of modality were observed in the prefrontal cortex that survived exclusion of task difficulty related activations. No effect of task-relevant information was observed in the anterior cingulate. Future comparisons of the mediation of selective attention need to consider the effects of task context and task difficulty. (c) 2005 Elsevier Inc. All rights reserved.

Reversing the emotional Stroop effect reveals that it is not what it seems: the role of fast and slow components

The relative contributions of slow and fast (online) components in a modified emotional Stroop task were evaluated. The slow component, neglected in previous research, was shown to lead to the prediction of a reversed emotional intrusion effect using pseudorandomly mixed negative and neutral stimuli. This prediction was supported in Experiments 1 and 2. In Experiments 3 and 4, a new paradigm was developed that allowed a more direct observation of the nature of disruptive effects from negative stimuli. The results provided a clear demonstration of the presence of the slow component. The fast component, which has generally been assumed to be the source of the interference, was shown, in fact, to have little or no role in the disruption.

False recognition of abstract versus common objects in older and younger adults: testing the semantic categorization account

Older adults often demonstrate higher levels of false recognition than do younger adults. However, in experiments using novel shapes without preexisting semantic representations, this age-related elevation in false recognition was found to be greatly attenuated. Two experiments tested a semantic categorization account of these findings, examining whether older adults show especially heightened false recognition if the stimuli have preexisting semantic representations, such that semantic category information attenuates or truncates the encoding or retrieval of item-specific perceptual information. In Experiment 1, ambiguous shapes were presented with or without disambiguating semantic labels. Older adults showed higher false recognition when labels were present but not when labels were never presented. In Experiment 2, older adults showed higher false recognition for concrete but not abstract objects. The semantic categorization account was supported.

Inverse effectiveness, multisensory integration, and the bodily self: some statistical considerations

A recent report in Consciousness and Cognition provided evidence from a study of the rubber hand illusion (RHI) that supports the multisensory principle of inverse effectiveness (PoIE). I describe two methods of assessing the principle of inverse effectiveness ('a priori' and 'post-hoc'), and discuss how the post-hoc method is affected by the statistical artefact of,regression towards the mean'. I identify several cases where this artefact may have affected particular conclusions about the PoIE, and relate these to the historical origins of 'regression towards the mean'. Although the conclusions of the recent report may not have been grossly affected, some of the inferential statistics were almost certainly biased by the methods used. I conclude that, unless such artefacts are fully dealt with in the future, and unless the statistical methods for assessing the PoIE evolve, strong evidence in support of the PoIE will remain lacking.

The dynamics of threat, fear and intentionality in the conduct disorders: longitudinal findings in the children of women with post-natal depression

This paper considers how environmental threat may contribute to the child's use of avoidant strategies to regulate negative emotions, and how this may interact with high emotional reactivity to create vulnerability to conduct disorder symptoms. We report a study based on the hypothesis that interpreting others' behaviours in terms of their motives and emotions - using the intentional stance - promotes effective social action, but may lead to fear in threatful situations, and that inhibiting the intentional stance may reduce fear but promote conduct disorder symptoms. We assessed 5-year-olds' use of the intentional stance with an intentionality scale, contrasting high and low threat doll play scenarios. In a sample of 47 children of mothers with post-natal depression ( PND) and 35 controls, children rated as securely attached with their mothers at the age of 18 months were better able to preserve the intentional stance than insecure children in high threat scenarios, but not in low threat scenarios. Girls had higher intentionality scores than boys across all scenarios. Only intentionality in the high threat scenario was associated with teacher-rated conduct disorder symptoms, and only in the children of women with PND. Intentionality mediated the associations between attachment security and gender and conduct disorder symptoms in the PND group.

A left-ear disadvantage for the presentation of irrelevant sound: manipulations of task requirements and changing state

Three experiments attempted to clarify the effect of altering the spatial presentation of irrelevant auditory information. Previous research using serial recall tasks demonstrated a left-ear disadvantage for the presentation of irrelevant sounds (Hadlington, Bridges, & Darby, 2004). Experiments 1 and 2 examined the effects of manipulating the location of irrelevant sound on either a mental arithmetic task (Banbury & Berry, 1998) or a missing-item task (Jones & Macken, 1993; Experiment 4). Experiment 3 altered the amount of change in the irrelevant stream to assess how this affected the level of interference elicited. Two prerequisites appear necessary to produce the left-ear disadvantage; the presence of ordered structural changes in the irrelevant sound and the requirement for serial order processing of the attended information. The existence of a left-ear disadvantage highlights the role of the right hemisphere in the obligatory processing of auditory information. (c) 2006 Published by Elsevier Inc.
