Maternal risk factors as predictors of developmental outcome in early childhood

This paper describes the rationale, procedures, and initial validation of an instrument which assesses distal environmental factors thought to negatively influence maternal caregiving ability. A sample of 36 lower class, single, black mothers (ranging in age from 14 to 19 years) of first born, full-term infants were included in an educational intervention program carried out during infants' first 12 months of life. The development of the maternal risk score (MRS) instrument was centered around four areas: maturity of mother, degree of planning of the mother, family support system and level of poverty. Initial, Year 1, Year 2, and Year 3 MRS scores were compared with infant development at one and two years as measured by the Bayley Scales, and at three years with the McCarthy Scales, using Pearson product-moment correlations. The initial MRS correlated negatively with the Bayley Mental Development Index (MDI) at Year 1 and also at Year 2 (N=−.38 and −.40 respectively, both significant at p<.05). The MRS for Year 1 showed significant negative correlations with the two Bayley MDIs: two and three year MRS scores were significantly related to three year McCarthy test scores. This screening instrument, which assesses qualitative aspects of the caretaking environment, appears to be a promising approach for identifying lower class mothers of infants who might be at risk for developmental disabilities.     

Social representations of the individual: a post-Communist perspective

Social representations of the individual are examined in three post-Communist Central European nations, i.e. the Czech Republic, Slovakia and Hungary, and in three West European nations, i.e. Scotland, England and France. All six nations share a common European history since the Renaissance and Humanism, based on such values as freedom, agency, individual rights and individual responsibility. Many of these values were rejected by the Communist regimes in which people lived for 40 years. Extreme forms of individualism developed in certain West European nations during the same period. In view of these historical events we have asked the following questions: Do people in the post-Communist countries of Central Europe, after 40 years of totalitarian collectivism, still adhere to the values of the common European heritage? What is the meaning of ‘the individual’ today, in Western democracies and in Central European post-Communist nations? Which issues are important for the well-being of the individual and how do they relate to the political and economic circumstances of those individuals? The results show that the values of the common European heritage in Central Europe have not been destroyed and that factors relating to the well-being of the individual differ between the two parts of Europe. These data are discussed in terms of the political and economic situations in Central and Western Europe, the relationship between language and social representations and the structure of social representations. © 1998 John Wiley & Sons, Ltd.     

Mental contrasting and conciliatory behavior in romantic relationships

When people in a relationship offend each other, it is important for them to behave in a conciliatory manner if they wish to reconcile. We tested in two studies if mental contrasting (versus other modes of thoughts) is an effective strategy for people to self-regulate their conciliatory behavior. In Study 1, we assessed student participants’ spontaneous mode of thought when thinking about an unresolved interpersonal transgression and measured their commitment to reconcile. Eight days later, we assessed their conciliatory behavior. Participants who spontaneously mentally contrasted reported more commitment to reconcile and showed sensible conciliatory behavior (i.e., based on their expectations of solving their interpersonal concern). In Study 2, romantic couples were invited into the lab and asked to identify unresolved incidents in which one partner (the perpetrator) had offended the other (the victim). After perpetrators were induced to mentally contrast or indulge about a successful reconciliation, we videotaped the couples discussing the incident. Only perpetrators who mentally contrasted showed sensible conciliatory behavior and reached effective reconciliation (measured right after the experiment and 2 weeks later). The findings imply that mental contrasting supports perpetrators to show conciliatory behavior when it promises to be successful, but discourages it when it seems futile or adverse, thereby protecting the relationship from further harm.

Sensory memory of structure-from-motion is shape-specific

Perceptual priming can stabilize the phenomenal appearance of multistable visual displays (Leopold, Wilke, Maier, & Logothetis, Nature Neuroscience, 5, 605–609, 2002). Prior exposure to such displays induces a sensory memory of their appearance, which persists over long intervals and intervening stimulation, and which facilitates renewed perception of the same appearance. Here, we investigated perceptual priming for the apparent rotation in depth of ambiguous structure-from-motion (SFM) displays. Specifically, we generated SFM objects with different three-dimensional shapes and presented them in random order and with intervening blank periods. To assess perceptual priming, we established the probability that a perceived direction of rotation would persist between successive objects. In general, persistence was greatest between identical objects, intermediate between similar objects, and negligible between dissimilar objects. These results demonstrate unequivocally that sensory memory for apparent rotation is specific to three-dimensional shape, contrary to previous reports (e.g., Maier, Wilke, Logothetis, & Leopold, Current Biology, 13, 1076–1085, 2003). Because persistence did not depend on presentation order for any pair of objects, it provides a commutative measure for the similarity of object shapes. However, it is not clear exactly which features or aspects of object shape determine similarity. At least, we did not find simple, low-level features (such as volume overlap, heterogeneity, or rotational symmetry) that could have accounted for all observations. Accordingly, it seems that sensory memory of SFM (which underlies priming of ambiguous rotation) engages higher-level representations of object surface and shape.     

Reappraisal and mindfulness: A comparison of subjective effects and cognitive costs

The present study investigated the relative effects of mindfulness and reappraisal in reducing sad mood and whether trait mindfulness and habitual reappraisal moderated the effects. The study also compared the extent to which implementation of these strategies incurred cognitive resources. A total of 129 participants were randomly assigned to receiving training in mindfulness, reappraisal, or no training prior to undergoing an autobiographical sad mood induction. Results showed that mindfulness and reappraisal were superior to no training, and equivalent in their effects in lowering sad mood. Compared to mindfulness, reappraisal resulted in significantly higher interference scores on a subsequent Stroop test, reflecting greater depletion of cognitive resources. Higher trait mindfulness, but not habitual reappraisal, predicted greater reductions in sadness across conditions. The study suggests that although mindfulness and reappraisal are equally effective in down-regulating sad mood, they incur different levels of cognitive costs.     

Contextualised behavioural measurements of personality differences obtained in behavioural tests and social observations in adult capuchin monkeys (Cebus apella)

We applied a new framework for behavioural research on personality differences in 26 adult tufted capuchin monkeys. Using the Behavioural Repertoire x Environmental Situations Approach, we generated systematically 20 non-lexical emic personality constructs that have high ecological validity for this species. For construct operationalisation, we obtained 146 contextualised behavioural measures repeatedly in 15 experimental situations and 2 group situations using computerised and video-assisted methods. A complete repetition after a 2–3-week break within a 60-day period yielded significant test–retest reliability from individual-oriented and variable-oriented viewpoints at different levels of aggregation. In accordance with well-established findings on cross-situational consistency, internal consistency was only moderate. This new and important finding highlights fundamental differences between behavioural approaches and judgment-based approaches to personality differences.     

Subjective Well-Being and Policy

This paper analyses whether the aggregation of individual happiness scores to a National Happiness Index can still be trusted once governments have proclaimed their main objective to be the pursuit—or even maximization—of this National Happiness Index. The answer to this investigation is clear-cut: as soon as the National Happiness Index has become a policy goal, it can no longer be trusted to reflect people’s true happiness. Rather, the Index will be systematically distorted due to the incentive for citizens to answer strategically and the incentive for government to manipulate the Index in its favour. Such a distortion would arise even if the measurement of subjective well-being correctly reflected actual happiness before the intervention of government. Governments in a democracy should establish the conditions enabling individuals to become happy. The valuable and important results of happiness research should be introduced into the political process. Each person should be free to pursue happiness according to his or her preferences. This process is supported by obedience to the rule of law, human rights and free media, as well as by extended political participation rights, decentralized public decision-making, an open and effective education system fostering upward mobility and the possibility to find suitable employment.     

Sociosexual orientation, commitment, and infidelity: a mediation analysis

Individuals with an unrestricted sociosexual orientation (SO) are less committed to their romantic relationships and more likely to engage in infidelity. Furthermore, commitment is negatively associated with tendencies to cheat. However, no previous research has examined the possible mediating role of commitment in the relationship between SO and infidelity. The current study examined whether commitment mediated the relationship between SO and willingness to engage in three types of cheating behaviors (Ambiguous, Deceptive, and Explicit). Results suggested that commitment partially mediated the relationship between SO and infidelity, such that unrestricted individuals had lower commitment, which in turn led to a greater likelihood of cheating. Implications of this association and directions for future research are discussed.     

Persistent effect of incubation temperature on stress-induced behavior in the Yucatan banded gecko (Coleonyx elegans)

Although variability in behavioral traits within animal populations is well documented, the mechanisms maintaining that variability are still insufficiently known. In this study, we examined whether differences in thermal environment during egg incubation can permanently organize nonsocial behavior across different contexts and situations in a lizard species. We incubated eggs of the Yucatan banded gecko, Coleonyx elegans (Squamata: Gekkota: Eublepharidae) at 3 constant temperatures (26, 28, and 30 °C) and raised juveniles separately under the same conditions until adulthood. We then subjected them to 3 behavioral tests within 2 different contexts: an open-field test and a test of antipredator behavior (stressful context) as well as a test of feeding behavior (nonstressful context). Individuals of both sexes incubated at 30 °C were consistently less active and showed lower frequencies of several stereotypic behaviors in the stressful contexts than did individuals incubated at 26 and 28 °C. The test of feeding behavior revealed no significant effect of incubation temperature on geckos' behavior. Thus, our study demonstrates that developmental plasticity may play an important role in producing variability in stress-induced behavior in lizards.
