To honor Fechner and obey Stevens: relationships between psychophysical and neural nonlinearities

G. T. Fechner (1860/1966) famously described two kinds of psychophysics: Outer psychophysics captures the black box relationship between sensory inputs and perceptual magnitudes, whereas inner psychophysics contains the neural transformations that Fechner's outer psychophysics elided. The relationship between the two has never been clear. Moreover, psychophysical power laws are found in almost every sensory system, yet the vast majority of neurons show sigmoid nonlinearities. Here, we selectively review the literatures on psychophysical and physiological nonlinearities and show how they can be placed within a framework for understanding the relationship between inner and outer psychophysics: a neural organization with a logical structure commensurate to outer psychophysical theory. In theoretical treatments of Stevens's law, the power law is a consequence of combining a Weber's law scaling of inputs with a Weber's law-like scaling of sensation magnitudes, yielding an exponent that is the ratio of the Weber constants. A neural derivation using physiological sigmoid nonlinearities should be commensurate to this internal logic. There is a class of models in which two nonlinear neural mechanisms (e.g., a sensory channel and the cortical numerosity mechanism tapped by magnitude estimation) are coupled through feedback, yielding power law behavior as an emergent property of the system, with an exponent that is a ratio of neural coupling strengths. Rather than a discrepancy between psychophysics and physiology, these models suggest complementarity between inner and outer psychophysics, because the Weber constants required for outer psychophysics modeling can be derived from the sigmoid nonlinearities of inner psychophysics.     

Male honor and female fidelity: implicit cultural scripts that perpetuate domestic violence

Two studies explored how domestic violence may be implicitly or explicitly sanctioned and reinforced in cultures where honor is a salient organizing theme. Three general predictions were supported: (a) female infidelity damages a man's reputation, particularly in honor cultures; (b) this reputation can be partially restored through the use of violence; and (c) women in honor cultures are expected to remain loyal in the face of jealousy-related violence. Study 1 involved participants from Brazil (an honor culture) and the United States responding to written vignettes involving infidelity and violence in response to infidelity. Study 2 involved southern Anglo, Latino, and northern Anglo participants witnessing a "live" incident of aggression against a woman (actually a confederate) and subsequently interacting with her.     

Discrepancies between implicit and explicit self-esteem: implications for narcissism and self-esteem instability

ABSTRACT There appear to be two forms of high self-esteem: secure high self-esteem (which is often linked with psychological health) and fragile high self-esteem (which is generally associated with poor psychological adjustment and impaired interpersonal relationships). Discrepant high self-esteem is a form of fragile self-esteem characterized by high explicit self-esteem and low implicit self-esteem. The present study examined whether discrepant high self-esteem was associated with narcissism and self-esteem instability in an undergraduate sample. Using multiple measures of implicit self-esteem, two basic findings emerged from the present study. First, participants with discrepant high self-esteem possessed the highest levels of narcissism. Second, participants with high explicit self-esteem and high implicit self-esteem displayed the most stable self-esteem. Findings are discussed in terms of secure and fragile high self-esteem.     

Perceived justice of available opportunities and self-esteem,collective esteem and social exclusion: A study of three religious groups in India

Groups have their own social realities which determine their perceptions of justice having impact on their well- being and consequent integration with the mainstream society. The objective of the present study was to understand variations in perceived justice in terms of opportunities existing in five different domains, i.e. social prestige, economic, educational, employment and political by the Hindu Majority (N = 100) and Muslim (N = 100) and Christian (N = 76) minorities in India. In addition, the study also aimed to understand the relationship of perceived justice with self-esteem, collective esteem and social exclusion. Male and female participants (N = 276) of the study were either of high or low caste, and were of employed or unemployed status from a north Indian city. The results indicate that justice perception is determined by religion and caste not by gender and employment status. The majority Hindus perceived significantly higher perceptions of justice than Christians and Muslims minorities on all four domains except education. For education the minority Muslim group had lower justice perceptions than Hindus and Christians who did not differ significantly. The three groups differed significantly in their ratings of social exclusion with maximum exclusion perceived by Christians and minimum by Hindus. Results have implications for development initiatives.     

Relation between sport and spatial imagery: comparison of three groups of participants

The literature suggests that sport may be considered a spatial activity and that engaging in spatial activities increases the capacity of an individual to implement mental imagery. Moreover, mental rotation calls upon motor processes that are heavily involved in sporting activities. For these reasons, the authors hypothesized that athletes ought to perform mental rotation tasks better than nonathletes. Also, athletes trained to react quickly to constantly changing environments should be faster at processing the information in a mental rotation task than athletes operating in more settled environments. The results of this study show that athletes performed the mental rotation task significantly faster than nonathletes. These results support the suggestion that there is a link between sport and the ability to perform mental image transformations; however, this ability may not be specific to the conditions in which the athlete performs.     

Relationship-contingent self-esteem and the ups and downs of romantic relationships

Relationship-contingent self-esteem (RCSE) emerges from perspectives on authenticity, need fulfillment, and relationship functioning and is an unhealthy form of self-esteem that depends on one's relationship. Four studies provided evidence of convergent, discriminant, incremental, and predictive validity for RCSE. Study 1 tested associations between RCSE and several conceptually related and unrelated constructs in multiple samples. In Study 2, the authors employed an event-contingent diary procedure to examine reports of self-esteem as a function of everyday relationship events. The association between event valence and changes in self-esteem became stronger with RCSE, and this interaction remained controlling for several parallel interactions by other constructs. Study 3 employed an interval-contingent diary procedure and found support for a mediation model in which the moderating role of RCSE largely occurred through momentary emotions, which in turn predicted momentary self-esteem. Study 4 sampled couples and found that partners who were both higher in RCSE felt more committed but not more satisfied or close.

Differential relationships between intergroup contact and affective and cognitive dimensions of prejudice

Research on affective dimensions of intergroup relationships suggests that positive effects of intergroup contact can generalize through establishing affective ties with outgroup members. However, research on cognitive dimensions emphasizes that it is often difficult to generalize positive contact outcomes. In this research, the authors examine whether affective and cognitive dimensions of prejudice bear different relationships to intergroup contact. Using data from a larger meta-analysis of contact effects, Study 1 demonstrates that affective indicators of prejudice typically yield stronger, inverse contact-prejudice relationships than such cognitive indicators as stereotypes. Study 2 replicates these trends in a survey study using multiple indicators of affective and cognitive dimensions of prejudice. Study 2 also shows significant, inverse relationships between contact and affective prejudice when contact is assessed either as number of outgroup friends or intergroup closeness. Together, these results suggest that affective dimensions of intergroup relationships are especially critical for understanding the nature of contact-prejudice effects.     

Parenting in Hawaii: Three cultural groups at the beach

This study shows systematic differences in parenting behaviour across three cultural groups in Hawaii. Japanese-, Caucasian- and Hawaiian-American parents (N =149) are observed as they interact with their young children at the beach. The observed families come to the beach in different groupings. Hawaiian groups are the largest, many consisting of five or more people. Most Japanese families resemble the ‘typical’ nuclear family: two parents and one or two children. More Caucasian and Hawaiian parents come to the beach alone with their children than do Japanese-American parents. Parents in the three groups spend their time differently. Japanese-American parents focus almost exclusively on their children. They play with, watch or take care of them for most of the observed time. They rarely engage in solitary activities, such as reading or sunbathing, or in social activities, such as talking with each other. Caucasian parents engage in solitary activities more frequently. They encourage children to entertain and care for themselves. Hawaiian parents interact extensively with other adults, and Hawaiian children play among themselves without prompting. The Hawaiian parents interact less frequently with their children than do parents in the other groups. These findings are discussed in terms of cultural differences in views of the parenting role, the range of people socializing children and childrearing emphases on independence vs dependence, aloneness vs social involvement and innovation vs imitation.     

Physical self-perceptions and self-esteem in adolescents participating in organized sports and religious groups

Drawing on the exercise and self-esteem model (EXSEM), the current study examined associations between sport activities and aspects of the self-system among adolescent members of sport groups. Youths attending religious groups were included in the study to allow for a test of generalization. Participants were 595 adolescents (sport groups: n = 355, M_age = 15.09 years, SD = 1.49, 54.6% female; religious groups: n = 240, M_age = 15.67 years, SD = 1.44, 53.8% female) who completed a series of paper and pencil measures detailing their involvement in sport activities (sport group only), their self-efficacy beliefs in the physical domain, perceived sport competence and attractiveness, as well as global self-esteem. A structural model was tested for sport youth, specifying an effect of sport activities on self-efficacy that, in turn, was expected to predict subjective sport competence and attractiveness. Finally, the model postulated effects of competence and attractiveness on self-esteem. The model test revealed a good fit. Multi-group models considering type of leisure group and sex pointed to parallel patterns in the associations of self-efficacy, competence, attractiveness, and self-esteem in the subgroups.     

Measurement invariance of the Mental Health Continuum-Short Form (MHC-SF) across three cultural groups

This study investigated the factorial structure and invariance of the Mental Health Continuum-Short Form (MHC-SF) across cultural groups from three nations, namely, the Netherlands, South Africa, and Iran (N = 1120). The three-dimensional structure of mental well-being was supported in all the groups. The results of measurement invariance testing confirmed the full metric and partial scalar invariance of the MHC-SF. The study also compared the latent means for the aspects of mental well-being in the three cultural groups, and found significant differences. The significance and implications of the results are discussed.     

The role of unstable self-esteem in the appraisal of romantic relationships

The relationship appraisals of individuals with stable and unstable forms of self-esteem were examined in two studies using undergraduate participants. Study 1 (N = 166) used indicators of relationship closeness and satisfaction whereas Study 2 (N = 125) examined relationship commitment. Across both studies, men with unstable high self-esteem reported more positive views of their relationships than other individuals. We believe that the fragile nature of their feelings of self-worth may have motivated these men to appraise their relationships positively in an effort to maintain and enhance their own tenuous feelings of self-worth. These findings suggest that men with unstable high self-esteem may use their romantic relationships to regulate how they feel about themselves.     

Test of structural relationships within a proposed exercise and self-esteem model

This study tested structural relationships within a model proposed to explain the manner in which self-esteem changes are associated with exercise experiences. As initially assessed by self-efficacies (EFFs) specific to physical tasks within a training program, we postulated that competence can generalize to feelings of global self-esteem (SE) through an intervening construct of perceived physical competence (PC). Three measures of EFF and two each of PC and SE were administered to 145 people in their mid- to late adulthood. Confirmatory factor analysis examined orthogonal and oblique versions of three measurement models and identified three distinct but correlated factors, each assessed by its hypothesized indicators. Alternative structural equation models were specified and tested using both normal and nonnormal estimation procedures. The proposed model provided the most parsimonious fit and explained 29% of the variance in SE. Confirmation of its structural relationships provides preliminary validity for model use in examining the manner in which exercise experiences influence levels of self-perception.     

Vulnerable self-esteem and depressive symptoms: prospective findings comparing three alternative conceptualizations.

Across diverse theoretical orientations, vulnerable self-esteem (SE) is thought to act as a diathesis for depression after life stress. In the present study, the roles of trait-level SE, low SE primed by depressed mood, and labile SE in prospectively predicting changes in depressive symptoms in a nonclinical sample (n = 192) were examined. Results indicated that labile SE predicted increases in symptoms. Furthermore, a 3-way interaction (Labile SE x Academic Stress x Initial Depression) suggested that in Ss who were initially asymptomatic, lability made Ss differentially vulnerable to increases in depressive symptoms after stress. In contrast to labile SE, trait-level SE and priming of low SE were relatively weak predictors of changes in depressive symptoms and did not interact with stress.     

Love at the cultural crossroads: Intimacy and commitment in Chinese Canadian relationships

The role of culture in romantic relationships has largely been investigated by examining variation between groups, rather than within groups. This study took a within‐group approach to examine the influence of Canadian and Chinese cultural identification on gender role egalitarianism, intimacy, and commitment in 60 Chinese Canadian dating couples. Results revealed that men's identification with mainstream Canadian culture was associated with their own and with their partner's greater intimacy, at least in part because of their greater egalitarianism. Conversely, women's identification with mainstream Canadian culture was associated with their partners' lower intimacy. Finally, women's identification with Chinese heritage culture was associated with their greater commitment, and some evidence suggested that this was because of their greater gender role traditionalism.     

On the risk of being a cultural chameleon: variations in collective self-esteem across social interactions

In the present study the authors used an event-contingent daily recording strategy, the Rochester Interaction Record, to examine the relation of perceived evaluations of a multicultural person's heritage group to the nature and quality of his or her social interactions. Hierarchical linear modeling showed that having an interaction partner who positively evaluated one's heritage culture was associated with significantly enhanced interaction intimacy, disclosure, and quality, as well as with feelings of personal acceptance. Moderator analyses revealed that individuals who possessed a chameleon-like cultural identity and those who had low public collective self-esteem were particularly reactive to how their heritage group was being evaluated.     

Parental self-esteem and behavior problems in children: Similarities between mothers and fathers

The relationship between parental self-esteem and behavior problems in children was investigated using 1624 married couple's responses from the National Survey of Families and Households. The sample was weighted to be nationally representative in terms of race and ethnicity. It was hypothesized that the existence of behavior problems among children would be associated with low self-esteem among parents and that the parent's gender, child's gender, parents' gender role attitudes, and parental employment would moderate this relationship. The results indicated that parental self-esteem is negatively associated with behavior problems in children. However, none of the moderating variables had a significant impact. This suggests that the relationship between parental self-esteem and behavior problems among children is robust and does not vary appreciably with the gender of the parent, the gender of the child, the attitudes of the parent, or the employment of the parent.     

Partner effects of Mexican cultural values: the couple and parenting relationships

In this investigation, the authors explored the impact of individuals' cultural values on their partners' relationship adjustment and perceptions of their parenting relationship. The authors examined Mexican cultural values of simpatía (i.e., harmonious interpersonal relationships) and respeto (i.e., respect for authority figures) using a sample of 50 Mexican-origin couples in southern Arizona. Congruent with their hypotheses, results supported the proposition that fathers' simpatía is positively associated with both relationship adjustment and the parenting relationship as reported by mothers, whereas fathers' respeto is negatively associated with both relationship adjustment and the parenting relationship as reported by mothers. However, the authors found little evidence of a contribution of mothers' cultural values to fathers' perceptions of either relationship adjustment or the parenting relationship. They interpret these findings to suggest that mothers' relationship adjustment and parenting relationship are more sensitive to and dependent on fathers' degree of traditional cultural values among Mexican-origin families.     

Within- and between-culture variation: individual differences and the cultural logics of honor, face, and dignity cultures

The CuPS (Culture × Person × Situation) approach attempts to jointly consider culture and individual differences, without treating either as noise and without reducing one to the other. Culture is important because it helps define psychological situations and create meaningful clusters of behavior according to particular logics. Individual differences are important because individuals vary in the extent to which they endorse or reject a culture's ideals. Further, because different cultures are organized by different logics, individual differences mean something different in each. Central to these studies are concepts of honor-related violence and individual worth as being inalienable versus socially conferred. We illustrate our argument with 2 experiments involving participants from honor, face, and dignity cultures. The studies showed that the same "type" of person who was most helpful, honest, and likely to behave with integrity in one culture was the "type" of person least likely to do so in another culture. We discuss how CuPS can provide a rudimentary but integrated approach to understanding both within- and between-culture variation.
