Habitual sleep duration and eating disorders in college students

To measure the relationship between habitual sleep duration and eating disorders, the responses of groups of 34 short- and 43 longer-sleeping college students to the EAT-26 Test were compared. The short-sleepers scored twice as high and were five times more likely to exhibit abnormal eating patterns than the longer-sleeping group.     

The sleep-promoting behaviors of habitual short- and longer-sleeping adults

Consistent with the view that habitual longer-sleepers are more concerned with their sleep, this group (n = 25) reported engaging in twice as many sleep-promoting behaviors as a group of short-sleepers (n = 25). The longer sleepers tended to use alcohol and the short sleepers food to promote sleep.     

Being better than others but otherwise perfectly normal: Perceptions of uniqueness and similarity in close relationships

The current research addresses individuals' self-generated thoughts regarding their own and others' relationships, examining the ways in which perceptions of uniqueness and similarity are manifested in judgments regarding own and others' responses to dissatisfying incidents. Consistent with the uniqueness bias, participants characterized their own relationships by a greater number of constructive responses and a smaller number of destructive responses relative to characterizations of others' relationships. Moreover, external raters judged own constructive responses to be more constructive than others' constructive responses. Consistent with the similarity bias, external raters judged items describing others' responses to be less frequently occurring and more extreme than their own responses. Also, this research revealed support for the claim that the similarity bias is more pronounced for destructive responses than for constructive responses. A recall task corroborated these findings, revealing very good recall for destructive responses enacted by others and poor recall for destructive responses enacted by oneself.     

Eating Disorder Prevalence and Symptoms for Track and Field Athletes and Nonathletes

This study explored coaches’ responses to stress, the perceived effects of stress, and the coping strategies coaches employed. Transcribed interviews with 12 world class coaches, based in the UK, were inductively content analyzed. A range of themes emerged describing coaches’ responses to stressors and the effects of stress. Specifically, coaches discussed psychological reactions, and suggested that their negative responses to stress could be projected onto their athletes. While structuring and planning was reported as a coping strategy, coaches described a limited use of psychological skills and tended to avoid stressors that provoked strain responses in efforts to manage stress. Results suggest that coaches should be aware of how they respond to stressors and the influence their responses might have on their athletes. Sport psychologists should help coaches to identify and develop the psychological skills and strategies required to cope with the demands of world class coaching.     

European American and Chinese parents' responses to children's success and failure: implications for children's responses

The authors examined cultural differences in parents' responses to their children's performance. In Study 1 (N = 421), Chinese 5th graders reported that their parents de-emphasized their academic success and emphasized their academic failure, whereas their American counterparts reported that their parents did the opposite. This partially accounted for Chinese (vs. American) children responding less positively to success and more negatively to failure. In Study 2 (N = 128), Chinese and American mothers' responses to their 4th and 5th graders' performance were observed in the laboratory. The cultural differences in children's reports of parents' responses documented in Study 1 were replicated; mothers' responses were also associated with children's subsequent performance. In addition, Chinese mothers were more involved than were American mothers, but their affect was similar. Taken together, the results suggest that parents' responses to children's performance may be a channel for cultural transmission and perpetuation of responses to performance.     

An Effect on Rorschach M Responses of a Boy's Relationship with his Mother

Summary: This paper is concerned with testing the hypothesis that children who have good relationships with their parents will more often give M responses to the Rorschach than will children whose relationships with their parents are not good. The sample consisted of 20 boys who were divided into two groups according to the number of their M responses. Their relations with their parents were tested by the Family Relations Test, The results supported only the hypothesis with regard to the boys, relationships with their mothers. This seems to indicate that the ability to make M responses develops at an early age when the relationship with mother is of overwhelming importance.     

Familiality of mood repair responses among youth with and without histories of depression

Affect regulation skills develop in the context of the family environment, wherein youths are influenced by their parents', and possibly their siblings', regulatory responses and styles. Regulatory responses to sadness (mood repair) that exacerbate or prolong dysphoria (maladaptive mood repair) may represent one way in which depression is transmitted within families. We examined self-reported adaptive and maladaptive mood repair responses across cognitive, social and behavioural domains in Hungarian 11- to 19-year-old youth and their parents. Offspring included 214 probands with a history of childhood-onset depressive disorder, 200 never depressed siblings and 161 control peers. Probands reported the most problematic mood repair responses, with siblings reporting more modest differences from controls. Mood repair responses of parents and their offspring, as well as within sib-pairs, were related, although results differed as a function of the regulatory response domain. Results demonstrate familiality of maladaptive and adaptive mood repair responses in multiple samples. These familial associations suggest that relationships with parents and siblings within families may impact the development of affect regulation in youth.     

The monitoring skills of troubled mothers: Their problems in defining child deviance

Thirty-three clinic-referred mother-child dyads were observed in their home settings and one of the home observations was videotaped. These pretreatment observations were analyzed to determine the degree to which mothers provided indiscriminate reactions to their children's prosocial/neutral and deviant responses. We suspected that these reaction tendencies were connected to maternal deficiencies in their monitoring of child behavior. To pursue this suspicion, monitoring performance was assessed by having the mothers watch their own videotaped home observations and, using their own definitions, code their children's positive and aversive responses. Professional observers then replicated this coding task. Results showed mothers and professionals to be in fair agreement in coding child positive responses, but in poor agreement coding the child aversive responses. Mothers tended to undercode these latter responses and to be highly inconsistent in their own coding. When measures of maternal coding bias were correlated with maternal indiscriminate child care reactions, the bias in coding child aversive responses proved to be associated, while the positive coding bias was not. Discussion of these findings was focused on maternal insensitivity as promoted by the mothers' conservative and ambiguous definitions of child deviance.This study was supported by research grant MH40227 from the National Institute of Mental Health.     

The effect of computer‐mediated communication on conformity vs. nonconformity: An impression management perspective

There is disagreement in the literature regarding whether those communicating in computer-mediated (CM) groups are attentive or oblivious to the social situation. There is evidence on both sides, with those in CM groups sometimes modifying their public responses and other times not. This apparent contradiction may be due in part to the impression that those in CM groups wish to convey and whether modifying their responses would help convey this impression. Specifically, whereas those in face-to-face (FTF) groups may strategically alter their public responses to present themselves as part of the group, those in CM groups may strategically alter their public responses to present themselves as separate from the group and unique on a positive dimension. The results of three experiments support this impression-management account: those in CM groups strategically altered their responses when doing so produced a desirable impression. The results further suggest that visual information about the group and social distance play important roles in affecting whether those in CM groups conform or not.     

Accountability and judgment processes in a personality prediction task

In this experiment, we investigated the impact of accountability--social pressures to justify one's views to others--on cognitive processing in a personality-prediction task. Subjects were presented with the responses of actual test-takers to 16 items from Jackson's Personality Research Form (PRF) and asked to predict how these individuals responded to an additional set of 16 items from the same test. Subjects were assigned to a no-accountability condition (they learned that all of their responses would be anonymous), a preexposure-accountability condition (they learned of the need to justify their responses before seeing the test-takers' PRF responses), and a postexposure-accountability condition (they learned of the need to justify their responses after seeing the test-takers' PRF responses). Preexposure-accountability subjects reported more integratively complex impressions of test-takers, made more accurate behavioral predictions, and reported more appropriate levels of confidence in their predictions than did either no-accountability or postexposure-accountability subjects. We conclude by considering possible psychological mediators of these effects as well as the broader theoretical implications of the findings for the development of contingency models of judgment and choice.     

An effect on Rorschach M responses of a boy's relationship with his mother.

This paper is concerned with testing the hypothesis that children who have good relationships with their parents will more often give M responses to the Rorschach than will children whose relationships with their parents are not good. The sample consisted of 20 boys who were divided into two groups according to the number of their M responses. Their relations with their parents were tested by the Family Relations Test. The results supported only the hypothesis with regard to the boys' relationships with their mothers. This seems to indicate that the ability to make M responses develops at an early age when the relationship with mother is overwhelming importance.     

Flexible emotional responsiveness in trait resilience

Field studies and laboratory experiments have documented that a key component of resilience is emotional flexibility--the ability to respond flexibly to changing emotional circumstances. In the present study we tested the hypotheses that resilient people exhibit emotional flexibility: (a) in response to frequently changing emotional stimuli and (b) across multiple modalities of emotional responding. As participants viewed a series of emotional pictures, we assessed their self-reported affect, facial muscle activity, and startle reflexes. Higher trait resilience predicted more divergent affective and facial responses (corrugator and zygomatic) to positive versus negative pictures. Thus, compared with their low-resilient counterparts, resilient people appear to be able to more flexibly match their emotional responses to the frequently changing emotional stimuli. Moreover, whereas high-trait-resilient participants exhibited divergent startle responses to positive versus negative pictures regardless of the valence of the preceding trial, low-trait-resilient participants did not exhibit divergent startle responses when the preceding picture was negative. High-trait-resilient individuals, therefore, appear to be better able than are their low-resilient counterparts to either switch or maintain their emotional responses depending on whether the emotional context changes. The present findings broaden our understanding of the mechanisms underlying resilience by demonstrating that resilient people are able to flexibly change their affective and physiological responses to match the demands of frequently changing environmental circumstances.     

Dysfunctional Cognitions in Children with Social Phobia, Separation Anxiety Disorder, and Generalized Anxiety Disorder

According to cognitive theories of anxiety, anxious adults interpret ambiguous situations in a negative way: They overestimate danger and underestimate their abilities to cope with danger. The present study investigated whether children with social phobia, separation anxiety disorder, and generalized anxiety disorder have such a bias, compared to a clinical and a normal control group. Children were exposed to stories in which ambiguous situations were described, and asked to give their interpretations, using open and closed responses. Results showed that anxious children reported more negative cognitions than control children. However, anxious children did not overestimate danger on the free responses, but they did judge the situations as more dangerous on the closed responses. Anxious children had lower estimations of their own competency to cope with danger than the control groups on both open and closed responses. The results indicate that children with anxiety disorders have dysfunctional cognitions about ambiguous situations.     

Cardiovascular responses to open-field stress in rats: sex differences and effects of gonadal hormones

We studied sex differences in cardiovascular responses to stress using a new radio-telemetry model in which freely-moving Spontaneously Hypertensive rats (SHR) are exposed to open-field novelty stress. This model allowed simultaneous assessment of cardiovascular and behavioural responses to psychological stress. Female SHR in the diestrous stage of their estrous cycle had markedly greater pressor and tachycardic responses to open-field exposure when compared to either female rats not in diestrous or male SHR. Treatment of ovariectomized SHR with estrogen alone had no significant effect on cardiovascular reactivity, while a combined treatment of estrogen and progesterone slightly, but significantly attenuated their pressor response to open-field stress. In addition, treatment of castrated male rats with testosterone significantly enhanced their pressor responses to stress when compared to values obtained before treatment. None of the hormone treatments had any significant effect on heart rate responses to stress. Neither at different stages of the estrous cycle nor after hormone treatments were there any marked changes in behavioural responses in the open-field, making it unlikely that the differences in cardiovascular stress responses were caused by changes in behavioural activity. These data demonstrate differences in cardiovascular stress responses that seem to be dependent on the stage of the estrous cycle. They suggest that particularly androgens, such as testosterone, may enhance pressor responses to stress. On the other hand, a combination of estrogen and progesterone, rather than estrogen alone, may have a small attenuating effect on cardiovascular reactivity.     

The Role of Pluralistic Ignorance in the Reporting of Sexual Harassment

There have been many attempts to explain how and why people report incidents of sexual harassment. One area that has been overlooked is the influence of the targets' social cognition processes on these reports, particularly social comparison processes such as pluralistic ignorance. Pluralistic ignorance is a social comparison phenomenon whereby individuals mistakenly believe they are in the minority. In the case of harassment, pluralistic ignorance occurs when individuals mistakenly interpret the behavioral responses of others to mistakenly believe that they are alone in their discomfort with harassment. We investigated the role of pluralistic ignorance in this process by exposing undergraduate students to sexist jokes while manipulating their access to behavioral responses of others. We measured their comfort level and their perceptions of the humor of the jokes. We compared their responses, most importantly, with how many jokes they read prior to “reporting” their discomfort with the jokes. We found evidence for the proposed role of pluralistic ignorance in the sexual harassment reporting process, whereby exposure to behavioral responses of others influences perceptions of others' relative comfort and humor, which in turn led to a decreased likelihood of reporting the harassment.     

CULTURAL MODELS OF INFANT EMOTIONS AND NEEDS AMONG THE GAMO PEOPLE OF SOUTHERN ETHIOPIA

How mothers perceive their infants’ emotions and their subsequent responses are influenced by cultural values and beliefs. Mothers who live in particularly harsh environments may have perceptions about their infants’ emotions that reflect not only cultural values but also constraints of the environment. In this qualitative study, 29 Gamo mothers living in rural Ethiopia were interviewed about perceptions of their infants’ emotions, how they felt about these emotions, and what they believed their infants needed in response. Through constant comparative analysis and thematic coding, several patterns emerged in mothers’ perceptions about their infants’ emotions and what constituted appropriate responses. Mothers said that their infants’ negative emotions were possibly related to illness and that appropriate responses were focused mostly on breastfeeding, complementary food, and needing to be held. Mothers also discussed their work demands and how they conflicted with their desire to respond to their infants; however, many mothers said that they relied on their older children to help. Mothers’ responses were centered on a parenting strategy aimed at promoting infant health and survival, which is consistent with research on parents living in rural environments who subsist by farming and have relatively high risk for infant mortality.     

Ingroup and outgroup minorities: Differential impact upon public and private responses

The experiment which is presented in this paper was designed to overcome some of the problems associated with previous research investigating the effects of social categorization and minority influence. Sixty-eight fourteen-year-old British Secondary School pupils indicated their attitudes towards a 'grant for pupils' before and after reading a text which advocated a minority position. The text was attributed as being the work of either pupils from their own school (ingroup minority) or from a school they discriminated against (outgroup minority). Responses were either made in ‘public’ (by telling subjects that other pupils would see their responses) or in ‘private’ (by subjects putting their responses into a ‘ballot box’). The results showed that on public responses ingroup minorities had more influence than outgroup minorities while there was no difference on private responses. Also, greater change occurred when responses were made in private than in public. These results are compatible with the intergroup analysis of minority influence.     

Continulty in the Life Story: Self-Defining Memories, Affect, and Approach/Avoidance Personal Strivings

To study affective responses to memories and their relationship to personal strivings, 117 participants (65 males, 52 females) wrote selfdefining memories and indicated their affective responses to the memories. A week later they generated personal strivings, rated them along 10 dimensions, and indicated the relevance of their memories to the strivings. Participants who recalled more memories relevant to the attainment of their strivings felt more positively about their memories. Additionally, participants who listed greater percentages of avoidance strivings also recalled more memories related to the nonattainment of their strivings. Participants with higher percentages of avoidance strivings also recalled less positive memories. In an extension of Emmons's (1986) research, participants' feelings about personal strivings were linked to their affective responses to memories generated a week earlier. These results support a goal-based theory of affect and a role for motivation in memory.     

The relations between intellectual disabilities,social information processing,and behaviour problems

Social information processing (SIP) in children with mild intellectual disabilities (MID) has been said to differ from SIP in children without MID. However, findings have been inconsistent and MID have been confounded with behaviour problems. It is not clear whether SIP is uniquely related to intellectual disabilities, to the behaviour problems of children with MID, or to both. In the present study, 56 children with MID and 31 children without MID between the ages of 10 and 14 years therefore completed a number of SIP tasks involving video vignettes and their externalizing behaviour problems were assessed. It was hypothesized that intellectual disabilities would be related to both SIP and behaviour problems. Findings show children with MID to encode more negative cues, generate more responses, and show more variability in their responses than children without MID. Children with MID also generated fewer assertive responses, evaluated assertive responses less positively, were less confident about the enactment of assertive responses, and selected fewer assertive responses than children without MID. Submissive responses were more often generated spontaneously by children with MID, more positively evaluated by them, and given more confidence for enactment by children with MID compared to children without MID. Regression analyses were conducted to assess the relations between SIP, MID, and behaviour problems. Variance in the generation of submissive responses was related to both intellectual disabilities and externalizing behaviour problems. Variance in the encoding of cues, the number of responses generated, the variability of generated responses, the evaluation of assertive and submissive responses, self-efficacy, and the selection of assertive responses was found to be related to intellectual disabilities. Variance in the generation of aggressive responses was related to externalizing behaviour problems. In other words, not responding assertively was related to intellectual disabilities while responding aggressively was related to behaviour problems.     

Selectivity in paternal and infanticidal responses by male mice: effects of relatedness, location, and previous sexual partners.

Male mice tend to be infanticidal to unrelated infants but parental to their own offspring. The present study examines three hypotheses that might explain this apparent discrimination. There was no evidence of selective infanticide toward infants encountered for the first time on the basis of kinship, location, or cues associated with previous sexual partners. However, males tended to direct more paternal responses toward their own unfamiliar infants than toward unrelated infants, infants encountered in the male's home cage than those in the cage of another male, and when cues associated with a previous sexual partner were present. Data suggested that the responses of females to male intruders might influence the responses of those males. It was concluded that the infanticidal responses of male mice are mediated by a particular state of the male but that males in a noninfanticidal state may vary their paternal responsiveness on the basis of direct and indirect cues concerning relatedness.
