Adults' perceptions of experimental modifications of durations of pauses and expiratory sounds in infant crying.

Durations of all pauses and expiratory sounds in a 10-sec bout of infant crying were digitally increased and decreased by 50% to create cries that varied in the duration of pauses and expiratory sounds. Ratings by 40 men and women showed a general monotonic effect of pause duration so that cries with increasingly shorter pauses were perceived to be more arousing, informative, and aversive. The monotonic effect for pause duration was enhanced in an interaction with expiration duration for perceptions of urgency. Results provide the 1st known experimental evidence of how variations in the temporal structure of infant crying differentially affect adults' perceptions and support views of the cry of the young infant as a graded signal.

Understanding and similarity in marriage.

The following conclusions appear to be justified: (1) There is no evidence that happiness in marriage is a function of understanding the mate or is related to the similarity of selves of the mates. (2) Evidence indicates that marital happiness is associated with similarity of self perceptions of the mates. (3) Husbands and wives are no more similar in self perceptions than randomly paired men and women. (4) Marital happiness is related to the conformity of men to self perceptions of their sex.

The link between parents' perceptions of the school and their responses to school bullying: Variation by child characteristics and the forms of victimization.

A growing number of researchers encourage parents to notify the school when their children are bullied and work collaboratively with the school to resolve the situation. However, there is limited research on factors that are associated with parents' responses to their child's victimization. Using data from an online survey of 773 parents of victimized students enrolled in 93 schools (elementary, middle, and high), the current study employed structural equation modeling to examine the association between parents' perceptions of the school's climate and parents' responses to their child's victimization. The results indicated that the more favorable parents' perceptions of the climate were, the less likely they were to contact their child's school or talk to their child in response to the victimization. The parents' perception of the climate and response choice also varied as a function of the child's age and the form of bullying experienced. These findings suggest that parents' perceptions of the school are associated with their responses to their child's victimization. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Effects of age and gender on perceived facial attractiveness.

Examined 2 alternative predictions: (1) that Ss would find others similar to themselves as most attractive or (2) that men would prefer younger women and women more mature men. 22 men and 25 women (aged 17–29 yrs), 16 men and 18 women (aged 30–49 yrs) and 18 men and 32 women (aged 50+ yrs) rated the physical attractiveness of 72 photographs of faces from similar age/gender categories. For all groups of Ss, perceived attractiveness declined with age of face, particularly for women's faces. In addition, most groups rated women's faces as more attractive than those of men, the exception being men under 30 yrs, who rated men higher.

Semantic networks for odors and colors in Alzheimer's disease.

Objective: Impairment in odor-naming ability and in verbal and visual semantic networks raised the hypothesis of a breakdown in the semantic network for odors in Alzheimer's disease (AD). The current study addressed this hypothesis. Method: Twenty-four individuals, half patients with probable AD and half control participants, performed triadic-similarity judgments for odors and colors, separately, which, utilizing the multidimensional scaling (MDS) technique of individual difference scaling analysis (INDSCAL), generated two-dimensional configurations of similarity. The abilities to match odors and colors with written name labels were assessed to investigate disease-related differences in ability to identify and conceptualize the stimuli. In addition, responses on attribute-sorting tasks, requiring the odor and color perceptions to be categorized as one polarity of a certain dimension, were obtained to allow for objective interpretation of the MDS spatial maps. Results: Whereas comparison subjects generated spatial maps based predominantly on relatively abstract characteristics, patients with AD classified odors on perceptual characteristics. The maps for patients with AD also showed disorganized groupings and loose associations between odors. Their normal configurations for colors imply that the patients were able to comprehend the task per se. The data for label matching and for attribute sorting provide further evidence for a disturbance in semantic odor memory in AD. The patients performed poorer than controls on both these odor tasks, implying that the ability to identify and/or conceptualize odors is impaired in AD. Conclusion: The results provide clear evidence for deterioration of the structure of semantic knowledge for odors in AD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality change during the transition to parenthood: The role of perceived infant temperament.

Examined the effects of 70 parents' (mean age 28.69 yrs) perceptions of infant temperament on their own personality during the transition to parenthood. Two assessments were made about 16 wks apart for 22 primiparous couples (mean time prebirth 6.5 wks and mean time postpartum 10.5 wks) and for 13 childless couples. Ss were administered both global/trait and situation-specific/state measures, including the Eight-State Questionnaire and the Perception of Baby Temperament Instrument, in order to assess efficacy expectations, personal control, anxiety, and depression. New parents rated their infant's temperament along 4 dimensions: activity, rhythmicity, adaptability, and positive mood. The parent group showed greater change than the nonparent group on a number of measures. New parents who perceived their infant as having an easier temperament experienced more positive change, whereas new parents who perceived their infant as more difficult experienced more negative change, especially in personal control. Differential results were found for the 4 temperament dimensions, with adaptability and positive mood most frequently related to personality changes. The findings also indicate that fathers showed personality change in relation to their infant's temperament more often than mothers.

Sex differences in sensitivity of the hypothalamic-pituitary-adrenal axis.

Two studies examined sex differences in responsiveness of the hypothalamic-pituitary-adrenal cortical axis, a major component of the stress response. The first measured pituitary-adrenal responses to ovine corticotropin-releasing hormone (oCRH) in 24 healthy men and 19 healthy women. Plasma adrenocorticotropin hormone responses to oCRH were significantly greater among women than among men. In contrast, cortisol concentrations were similar in both groups, though elevations were more prolonged in women. Differences in corticotropin-releasing activity between men and women may help account for these findings; such differences in central components of the stress response might play a role in the known epidemiological differences in diseases of stress system dysregulation between men and women.

Gender-Specific Misperceptions of College Student Drinking Norms.

This study evaluated perceptions of same-sex and opposite-sex gender-specific versus gender-nonspecific drinking norms among college students (115 men, 111 women). This research is consistent with previous findings that college students overestimate the quantity and frequency of drinking among their gender-nonspecific peers and demonstrates that both men and women overestimate the quantity and frequency of the drinking of their same-sex peers. The findings suggest that perceived same-sex norms are more strongly associated with problematic drinking than are gender-nonspecific norms and that perceived same-sex drinking norms are stronger predictors of alcohol consumption for women than for men. Results suggest that interventions incorporating normative feedback should be framed differently for women than for men. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Women and men as organizational development practitioners: An analysis of differences and similarities.

Determined the values, practices, and extent of differences between women and men as organization development (OD) practitioners in the present and in the future. 150 female and 266 male members of 3 industry professional groups completed a questionnaire developed to assess practitioner's values and practices. Results indicate that in general both females and males relied less on traditional social–psychological and group-based methods of consulting and more on interventions aimed at helping organizations achieve their desired future states. In addition, general intervention usage between women and men did not differ significantly. Regarding the values of OD practitioners, findings indicate that women and men have very similar perceptions about what is important in the field today. However, females placed far more importance on humanistic values in OD work for the future than did men. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Content and grammatical sex bias on the Interpersonal Trust Scale and differential trust toward women and men.

Modified the items on the Interpersonal Trust Scale (ITS) to specify the sex of the reference groups to be trusted in order to study possible content and grammatical sex bias in responses to the ITS and to study whether men and women differ in their trust toward men and women. There was clear evidence for both masculine content sex bias and grammatical sex bias in responses by both college men and women (192 and 322 Ss, respectively). The trust scale provides a conservative estimate of trust toward women and indicates a critical need for ITS-trust-toward-women studies. Men and women indicated greater trust toward women than toward men or non-sex-specified referents wherever comparisons were possible. These findings coupled with differences between J. B. Rotter's trust concept and factors of trust on his scale suggest that 2 aspects of trust are sex linked and also suggest the importance of testing the implicit hypothesis that more important trusting decisions are made toward men than toward women. This study extends sex bias research to personality measures, distinguishes 2 new types of sex bias, and provides a methodology for testing the effects of these biases.

Women's responses to young infants' cries.

Women's caregiving and perceptual responses to young infants' cries were assessed as a function of parity and cry cause. Ss cared for a crying infant manikin in a simulated baby-sitting situation. Mothers and nonmothers were quite similar in basic features of their caregiving behaviors, suggesting that the effects of parity may be to fine-tune skills that many women bring to the task of caring for young infants. The specific cause of the cry (hunger or pain) was associated with few differences in caregiving behavior, even though a subsequent perceptual task showed that Ss reliably discriminated the two cries. Further analyses of the perceptual data indicated that cry sounds communicate information about the general distress level of the infant better than information about specific causes. Thus, although the sound of the cry may inform caregivers about overall distress level, caregiving behaviors appear to be determined by additional factors.

Sex differences in perceptions of desirable body shape.

Using a set of 9 figure drawings arranged from very thin to very heavy figures, 248 male and 227 female undergraduates indicated their current figure, their ideal figure, the figure that they felt would be most attractive to the opposite sex, and the opposite sex figure to which they would be most attracted. For men, the current, ideal, and most attractive figures were almost identical. For women, the current figure was heavier than the most attractive figure, which was heavier than the ideal figure. Both men and women erred in estimating what the opposite sex would find attractive. Men thought women would like a heavier stature than females reported they like, and women thought men would like women thinner than men reported they like. Results suggest that, overall, men's perceptions serve to keep them satisfied with their figures, whereas women's perceptions place pressure on them to lose weight. The sex differences reported are probably related to the greater incidence of dieting, anorexia, and bulimia among American women than among American men.

An integrative cultural view of achievement motivation: Parental and classroom predictors of children's goal orientations when learning mathematics in Korea.

Our goal was to identify how students' perceptions of their parents shape the kind and degree of motivational goal orientations that they adopt in their mathematics classroom, broadening the application of achievement goal orientation theory and self-determination theory to students in Korea. Two groups of students participated, one from a middle school located in a large metropolitan area and the other from a small city high school. Multisample path analysis of data from both groups revealed that Korean students' different goal orientations were predicted by their perceptions of parental goals and motivating styles and by their perceptions of classroom goal structures, mediated by different types of self-regulated motivations. Particularly interesting was the finding that Korean students' degree of mastery goal adoption was associated mostly with identified regulation, not with intrinsic motivation, and predicted by their perceptions of their parents' motivating styles, both autonomy supportive and controlling, in addition to perceptions of parents' mastery goals. Perceptions of classroom goals were stronger predictors of students' own goals than were perceptions of parents' goals and motivating styles. We offer an integration of self-determination theory and achievement goal theory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Parents' influence on children's achievement-related perceptions.

Two aspects of the relation between parents' perceptions of their children and children's self- and task perceptions in math and English were investigated: (a) the mediating role of parents' perceptions between grades and adolescents' self-perceptions and (b) the gendered nature of parents' perceptions. Data for this study are part of a longitudinal investigation (the Michigan Study of Adolescent Life Transitions). Data from 914 sixth-grade adolescents and their parents are used in this article. Results showed that parents' perceptions mediate the relation between children's grades and children's self and task perceptions in both domains. Parents' perceptions had a stronger influence on children's perceptions than children's own grades. Significant but low correlations between gender and self and task perceptions were found in both math and English. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of mothers' perceptions of children's competence: The moderating role of mothers' theories of competence.

There is much evidence that parents' perceptions of children's competence affect the development of children's academic functioning. In the current research, the possibility that this is moderated by parents' theories about the stability of competence was examined. In a 2-wave, 1-year study of 126 children (9 to 12 years old) and their mothers, children's academic functioning (i.e., grades, perceptions of competence, attributions for performance, and mastery orientation) and affective functioning (i.e., self-esteem and depressive symptoms) were examined. Among mothers with relatively high entity theories, their perceptions acted as self-fulfilling prophecies foreshadowing children's academic and affective functioning over time. However, among mothers with relatively low entity theories, mothers' perceptions did not predict children's academic and affective functioning.

Perceptions of women and men as entrepreneurs: Evidence for differential effects of attributional augmenting.

It was hypothesized that perceptions of women who become entrepreneurs are enhanced by attributional augmenting because they adopt this role despite major obstacles to doing so. In contrast, attributional augmenting was expected to operate to a lesser degree for men who become entrepreneurs because they presumably face weaker obstacles. Three studies offered support for these hypotheses; all of these investigations used between-subjects designs in which women and men shown in standard-format photos were described to different groups of raters as being either entrepreneurs or managers. As predicted, raters assigned significantly higher scores to women, but not to men, when they were described as entrepreneurs. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Social phobia and positive social events: The price of success.

Patients with generalized social phobia (N?=?32; 16 men, 16 women) and nonclinical control participants (N?=?32; 16 men, 16 women) took part in a social interaction that was manipulated to be successful or unsuccessful. Participants rated their ability, perceptions of others' standards, social goals, and emotional responses before and after the interactions. As predicted, the successful social interaction produced a somewhat negative response in patients with social phobia. Social success led to self-protective social goals, negative emotional states and perceptions that others would expect more in future interactions. These results indicate that positive social events may not be processed in a way that leads to a revision of negative self- and social judgments in patients with social phobia.

Perceptual organization of acoustic stimuli by budgerigars (Melopsittacus undulatus): III. Contact calls.

We trained budgerigars by operant conditioning to discriminate among a set of contact calls in a same–different task and analyzed response latencies from this task by using multidimensional-scaling (MDS) and cluster-analysis procedures. Humans listened to the same calls and indicated the similarity between pairs of calls by a direct rating procedure. An MDS program ({sindscal}) was used to arrange these complex acoustic stimuli in multidimensional space reflecting perceptual organization. Multiple regression techniques were used to identify the acoustic characteristics of contact calls that were correlated with the peceptual dimensions obtained from MDS. A number of spectral characteristics (e.g., peak frequency, rate of frequency modulation, and concentration of spectral energy) emerged as important for both budgerigars and humans, but the relative salience of these cues differed for the two species. Additional tests with two groups of budgerigars—cagemates and noncagemates—showed that experience with calls can change the salience of various acoustic characteristics used for perceptual organization and individual recognition.

Assumed similarity measures as predictors of team effectiveness.

"The present investigations test the hypothesis that group effectiveness is related to the interpersonal perceptions which members of the group have toward one another. Interpersonal perceptions were measured by correlating identical questionnaires which subjects were instructed to fill out (a) describing themselves, (b) predicting the responses of their preferred co-worker, and (c) predicting the responses of their rejected co-worker." The assumed similarity score of the team's most preferred work companion was found to be negatively correlated with a criterion of team effectiveness.

Assessing children's competence: Mothers' and teachers' ratings of competent behavior.

The purposes of this study were to test the replicability of the factor structure of the Health Resources Inventory (HRI; E. L. Gesten [see PA, Vol 57:7209]) for teachers, to describe the factor organization of the HRI when used with parents, and to assess the strength of agreement between parents' and teachers' views of children's competence. Parents' ratings were available for 269 children (ages 4 to 12 years), and teachers' ratings were gathered for a subset of 102. Analysis of teachers' responses confirmed a 5-factor structure of the HRI. The factor structure for mothers closely mirrored that of teachers. The similarity of factor structure argues for the usefulness of the HRI in assessing children's competence at home and school. The relatively modest correlation between mothers' and teachers' ratings suggests possible setting differences in children's behavior and/or variance related to rater source.
