Anticipated emotional and behavioral responses to ambiguous rejection by a significant other, friend, or acquaintance.

Although there is an extensive literature on interpersonal rejection, individual studies that have examined adults' emotional and behavioral responses to rejection have tended to limit their scope to a specific category of rejector (e.g., acquaintances). As a result, prior research has failed to systematically investigate whether individuals' emotional and behavioral responses to perceived rejection differ as a function of the role of the potential rejector. In the present study, a total of 481 participants read two scenarios describing hypothetical situations in which rejection by a specific individual (i.e., significant other, friend, or acquaintance) was ambiguous. After each scenario, participants rated the extent to which they would be likely to anticipate (a) experiencing various negative emotions (e.g., upset) and (b) engaging in various behavioral responses (i.e., act friendly, retaliate, complain, avoid) to the potential rejector. Overall, the potential of being rejected by another person with whom one has a close and valued relationship (i.e., a significant other and, to a lesser degree, a friend) was associated with heightened negative emotion and a heightened likelihood of engaging in an active response, either prosocial (i.e., act friendly) or antisocial (i.e., retaliate or complain). In contrast, potential rejection by an acquaintance was associated with relatively little negative emotion and relatively little desire to engage the other (i.e., avoid). In sum, the participants' relationship with specific individuals was found to influence both the intensity of their anticipated negative emotional response to ambiguous rejection and the pattern of their anticipated behavioral response to the potential rejectors.

Adults' attitudes toward children, adolescents, and adults who are obese and tax-funded programs to combat obesity.

The goals of the present study were to assess (1) adults' patterns of beliefs about and attitudes toward children, adolescents, and adults who are obese and (2) their attitudes toward hypothetical tax-funded programs designed to combat obesity in children, adolescents, and adults. A total of 267 participants, ranging in age from 19 to 88 years old, were recruited through Amazon's Mechanical Turk (MTurk) to participate online in the present study. The participants rated adults who are obese less favorably, and as less malleable, than children or adolescents who are obese. Furthermore, they were less supportive of tax-funded programs designed to combat obesity in adults than children or adolescents. In general, the participants' relatively unfavorable response to adults who are obese appears to be associated with the beliefs that older individuals who are obese are relatively unchangeable and have heightened personal fault for their plight.

Role of Fault Attributions and Other Factors in Adults' Attitudes Toward Hypothetical Children With an Undesirable Characteristic.

A total of 184 adults read descriptions of six hypothetical children with various undesirable characteristics (i.e., being extremely overweight, extremely aggressive, extremely shy, a poor student, a poor athlete, displaying symptoms of attention deficit hyperactivity disorder). Following each description, the participants were asked to rate how much they disagree or agree that the child, the child's parents, and the child's biological condition (i.e., "something wrong inside the child's body or brain") are at fault for the onset and the perpetuation of the undesirable characteristic. In addition, the participants were asked to rate their attitude toward each child using a 100-point "feeling thermometer." Analyses of the participants' various fault attribution ratings revealed that they tended to agree more strongly that a child's parents and his/her biological condition are at fault for the onset and the perpetuation of the child's undesirable characteristic than is the child him/herself. Despite the participants' reluctance to blame a hypothetical child for his/her undesirable characteristic, regression analyses revealed that, in general, the more they blamed the child for the onset of his/her undesirable characteristic, the more negative their attitude was toward the child. However, the participants' ratings of the extent to which the child's parents or biological condition are at fault for the onset and the perpetuation of the child's undesirable characteristic were not found to be associated with their attitude toward any of the children. Similarities and differences between the present findings and those reported in prior studies involving younger individuals are addressed.

Young Children's ability to Discriminate between Antisocial and Prosocial Teases.

The present study was designed to (a) examine 5- to 8-year-old children's ability to discriminate between antisocial and prosocial teases and (b) determine whether their age and experiences within the home are associated with their ability to recognize these two types of teases. Results revealed that the 5- to 8-year-old children were able to discriminate between antisocial and prosocial teases. Although the children's parents or legal guardians indicated that the children had more frequent experience with prosocial than antisocial teases in the home, (a) the children were better able to correctly identify the intent of antisocial teasers than prosocial teasers and (b) the parents or legal guardians (correctly) indicated that their child would be better able to recognize an antisocial tease than a prosocial tease. Despite the finding that the children's comprehension of antisocial teasing tended to exceed their comprehension of prosocial teasing, the findings indicate that being relatively young (i.e., 5-6 years old vs. 7-8 years old) and having relatively frequent experience with antisocial teasing in the home may be associated with some children's difficulty in recognizing the intent behind antisocial teases.

Destigmatization by Association: Improving Children's Reactions to an Obese Storybook Character.

Second- through fourth-grade students were read a storybook that described a typical boy who interacted with an obese boy for one of four reasons (sympathy, curiosity, teacher instructed, or no reason) to explore the manner in which a typical storybook character's reason for associating with an obese storybook character influences children's responses to both characters. Results revealed that the children responded more favorably to the obese storybook character after than before learning about the typical storybook character's association with him, especially when the typical storybook character's reason for association was presented as internally motivated (sympathy or curiosity). In contrast to "stigma by association" findings reported in prior research, the children also responded more favorably to the typical storybook character after than before his association with the obese storybook character.

Individual Differences Associated with Emotional and Behavioral Responses to Ambiguous Social Situations in which Rejection Might be Inferred.

This study sought to examine the extent to which undergraduates' experiences with and attitudes relevant to rejection may be associated with their emotional and behavioral responses to ambiguous social situations in which rejection might be inferred. Undergraduate students completed questionnaires that assessed their experiences with and attitudes relevant to being rejected. Next, each participant read six hypothetical scenarios that described various situations that could be interpreted as interpersonal rejection. Following each scenario, participants completed questionnaires that assessed their emotional and behavioral responses to the hypothetical situation. Analyses revealed that the participants' experiences with rejection (and, to a lesser extent, their rejection-relevant attitudes) were associated with a negative emotional response and some negative behavioral responses. In sum, when another individual's interpersonal behavior has an uncertain intent, undergraduates' prior experiences with rejection may be especially important in determining the extent to which they feel and act as if they have been rejected.

Children's Perceptions of Hypothetical Peers With Undesirable Characteristics: Role of the Peers' Desire to Change, Source of Effort to Change, and Outcome.

The present study, involving sixth- to eighth-grade students, is an extension of a prior investigation (Barnett, Livengood, Sonnentag, Barlett, & Witham, 2010) that examined children's perceptions of hypothetical peers with various undesirable characteristics. Results indicate that children's perceptions of hypothetical peers with an undesirable characteristic are influenced by the peers' desire to change, the source of effort to change, and the peers' success or failure in changing the characteristic. The children anticipated responding more favorably to peers who were successful in overcoming an undesirable characteristic than peers who were unsuccessful. Regardless of the peers' outcome, the children anticipated responding more favorably to peers who tried to change than peers who relied on the effort of adult authorities to motivate change. The children perceived successful peers as experiencing more positive affect than their unsuccessful counterparts, especially if the success was presented as a fulfillment of the peers' desire to change their undesirable characteristic. Finally, the children's ratings reflected the belief that, among peers who failed to change their undesirable characteristic, lacking the desire to change increases the relative likelihood that the characteristic will be permanent.

Human serum transferrin fibrils: nanomineralisation in bacteria and destruction of red blood cells.

Fibrils formed by human serum transferrin [(1-3 µM) apo-Tf, partially iron-saturated (Fe0.6 -Tf) and holo-Tf (Fe2 -Tf) forms], from dilute bicarbonate solutions, were deposited on formvar surfaces and studied by electron microscopy. We observed that possible bacterial contamination appears to give rise to long, pea-pod-like (PPL) structures for Fe2 -Tf, attributable to the formation of polyhydroxybutyrate (PHB) storage granules, under the nutrient-limiting conditions used. These PPL structures contained periodic nanomineralisation sites susceptible to uranyl stain. Extended incubation of transferrin solutions (about four days) gave rise to extensive transferrin fibril structures. Optical microscopy and AFM studies showed that red blood cells (RBCs) readily adhere to these fibrils. Moreover, the fibrils appear to penetrate RBC membranes and to induce rapid cell destruction (within about 5 h). It is speculated that in situations in vivo where transferrin fibrils can form, such interactions might have adverse physiological consequences, and further studies could aid the understanding of related pathological events.

Role of fault attributions and desire, effort, and outcome expectations in children's anticipated responses to hypothetical peers with various undesirable characteristics.

A total of 137 third- through eighth-grade students were asked to respond to a series of statements concerning 6 male peers described as having various undesirable characteristics (i.e., poor student, poor athlete, extremely overweight, extremely aggressive, extremely shy, or having the symptoms of attention deficit hyperactivity disorder). The aggressive peer and the overweight peer consistently elicited the least favorable reactions from the children. For all 6 peers included in the study, the more strongly the children agreed that a peer was at fault for his undesirable characteristic, the less favorably they anticipated responding to that peer. In contrast, the children's expectations concerning a peer's desire to change, effort to change, and success in changing an undesirable characteristic were generally unrelated to their anticipated responses to that peer. The children demonstrated the general belief that desire backed by effort leads to success in overcoming an undesirable characteristic, but lack of effort leads to failure regardless of the peer's desire or lack of desire to change the characteristic.

Children's anticipated responses to hypothetical peers with undesirable characteristics: role of peers' desire to change, effort to change, and outcome.

The authors explored the extent to which 5th- and 6th-grade students' anticipated responses to hypothetical peers with undesirable characteristics (e.g., being overweight) are influenced by information that each peer (a) desired (or did not desire) to change the characteristic, (b) exerted effort (or did not exert effort) to change the characteristic, and (c) was successful (or unsuccessful) in changing the characteristic. In general, the children anticipated responding more favorably to peers who were successful in overcoming an undesirable characteristic than those who were unsuccessful. However, across both outcome conditions, peers who wanted to change and exerted effort to change were rated more favorably than were peers who reported no effort to change an undesirable characteristic, regardless of whether or not they had expressed a desire to change that characteristic. For peers whose failure to change an undesirable characteristic was associated with no effort to change, those who expressed a desire to change were rated more favorably than those who expressed no desire to change.

Factors associated with children's anticipated responses to ambiguous teases.

The authors used two studies involving 5th- and 6th-grade children to examine factors potentially associated with individual differences in children's perceptions of and anticipated responses to ambiguous teases. Study 1 assessed the extent to which the children would expect recipients to feel hurt in response to a series of ambiguous teases and whether the children would perceive those teases as more like antisocial or prosocial teases. In Study 2 the children were asked to evaluate emotional and behavioral responses to ambiguous teases with various gender compositions of the teaser-target dyad. Despite some gender of participant differences, the studies demonstrated that children with relatively negative attitudes toward teases and relatively negative experiences as recipients of teases tended to interpret ambiguous teases as if they were meant to be hostile and antisocial.
