Loving and angry? Happy and sad? Understanding and reporting of mixed emotions in mother–child relationships by 6‐ to 12‐year‐olds

The Evaluative Space Model of emotions allows for the coactivation of positive‐appetitive and negative‐avoidant systems, but few studies have examined mixed emotions in child development. Existing research suggests children's understanding of opposite valence emotion combinations emerges by approximately 11 years of age. However, it is not yet clear whether various opposite valence combinations are understood at different ages, nor whether children can understand them in others before they have experienced such mixed emotions themselves. Semi‐structured interviews with 97 children investigated whether they regarded six combinations of opposite valence mixed emotions as possible, could provide reasons for them, and report their own experience of each in the context of mother–child relationships. Both understanding that such combinations are possible and ability to provide reasons for them increased after age 6 and up to age 11, but were still incomplete in 12‐year‐olds. Understanding of different opposite valence combinations developed at different rates. At each age, fewer children who showed understanding of these combinations in others reported having had a similar experience themselves. The findings suggest a need to systematically examine a range of mixed emotions in order to develop a comprehensive theory of the development of mixed emotion understanding. They also suggest extending research into adolescence.     

Attributions of Responsibility for Obesity: Narrative Communication Reduces Reactive Counterarguing Among Liberals

Informed by theory and research on attributions and narrative persuasion, we compared the effectiveness of narrative and nonnarrative messages in changing attributions of responsibility for causes and solutions related to obesity in the United States. We randomly assigned 500 adults to view one of three messages (narrative, evidence, and a hybrid of the two) emphasizing environmental causes of obesity, or a no‐exposure control condition. The narrative condition increased the belief that societal actors (government, employers) are responsible for addressing obesity, but only among liberals. This pattern of results was partially explained by the success of the narrative condition in reducing reactive counterarguing, relative to the evidence condition, among liberals. We conclude with theoretical and practical implications.     

The role of self-esteem in the experience of envy

It is the thesis of this paper that although analysts have always recognized that narcissistic injury may trigger envious feelings, the significance of self-esteem as both a motivator and response to envious feelings has not yet been sufficiently explored. Traditional drive-defense or object instinctual explanations tend to diminish awareness of the importance of self-esteem in the experience of envy. The focus on drives or repetition of early patterns of object relations does not always take into account the significance of the cycle in which damaged self-esteem leads to envy, the component parts of which may cause further damage to self-esteem, leading to more envy, and so on. I am suggesting that it is often an attempt to avoid painful injury to one's self-esteem, as well as the related attempt to maintain a positively colored sense of self, and not a repression of drives or a repetition of some aspect of early object relationships which must be understood in order to fully comprehend both feelings of envy and the need to keep such feelings out of conscious awareness.     

Ventral scent marking in Meriones unguiculatus may contribute to thermoregulation

Three experiments were conducted with adult male Meriones unguiculatus in an attempt to demonstrate that ventral scent marking can act to transfer body heat to the object marked. Experiment 1 showed that surgical removal of the ventral gland pad reduced the amount of heat transferred by 50%, even though intact and glandless animals did not differ in the average frequency of scent marking. Experiment 2 demonstrated that the difference in heat transfer due to the presence or absence of the scent pad was not due to differential pressure applied to the substrate during marking. Experiment 3 showed that the pattern of ventral hair spread that occurs as an animal moves over an object is different between intact and glandless animals but that this difference does not account for the difference in heat transfer. It is suggested that heat transfer to the environment with ventral scent marking may increase thermoregulatory competence and also may function to volatilize sebum used in chemocommunication.     

Components of reward in social dilemmas

A social dilemma (Dawes, 1980) may be defined as a situation in which a collection of individuals is faced with a conflict between maximizing selfish interests and maximizing collective interests. The dilemma is based on the fact that if all choose to maximize selfish interests, all are worse off than if all choose to maximize collective interests. In a decomposed social dilemma (Pruitt, 1967), the outcomes are divided into two components: one component is based on one's own choice and the second component is based on the choices made by the others. Using 3-person decomposed games, two types of incentives were contrasted: a positive incentive (bonus) for cooperative choices and a negative incentive (penalty) for noncooperative choices. Two experiments were conducted using male college students. The results of both experiments showed that the positive incentive evoked a higher level of cooperation than the negative incentive. The results are discussed in terms of nonadditive utility components, Pruitt's motivational interpretation, and Kelley and Thibaut's (1978) theory of interdependence.     

Validity of post-proline splitting dipeptidyl aminopeptidase activities in the cerebrospinal fluid for neurologic and psychiatric diagnosis

The dipeptidyl-peptidase activity of 650 liquores cerebrospinalis was obtained by means of the substrate Gly-Pro-NHNp (Gly-Pro-4-nitroanilid) at pHs of 5.5 and 7.4. In comparison with a reference collective, the suitability of the method as a supplementary liquor parameter in neurological psychiatric diagnosis was examined. The introduction of the measurement at pH 7.4 can be particularly recommended for the distinguishing of bacterial and nonbacterial meningitis.     

Relationship between trust in appraisal and appraisal effectiveness: A field study

The current study examined the influence of trust in the appraisal system on ratees' reactions to performance evaluations. One-hundred and sixty eight bank tellers completed an instrument that assessed their trust in the appraisal system, appraisal satisfaction, perceived utility of evaluations, behavioral intention to improve performance, and intention to leave the job. Trust and performance evaluations were significant predictors of ratee reactions to appraisals and intention to improve on performance weaknesses. In addition, performance ratings were a better predictor of intention to improve on performance weaknesses for ratees who had high trust in the appraisal system. Implications for future research and practice are discussed.An earlier version of this paper was presented at the Annual Meeting of the Society of Industrial and Organizational Psychology, Miami, Florida, April, 1990.     

Internalizing and externalizing characteristics of sexually and/or physically abused children

This study evaluates the behavioral consequences of childhood abuse (sexual, physical, or both), with particular focus on prevalence of posttraumatic stress disorder (PTSD). Three abuse type groups and nonabused controls were contrasted on behavioral rating scales and on structured psychiatric interview data. The participants (109 abused children and 16 normal control children) were recruited from Arkansas Children’s Hospital and local agencies for abused children. As expected, proportionately more females than males were sexually abused. Overall, males were rated as more disturbed than females. Type of abuse did not consistently influence behavioral ratings. Externalizing scores were significantly higher than internalizing scores in all abused groups. PTSD was diagnosed in 50% of the abused children, with a higher rate for boys who had been sexually abused as opposed to physically abused only (58% versus 13%). The most frequent comorbid condition with PTSD was Separation Anxiety. Sexually abused boys were hospitalized for psychiatric treatment at a higher rate than were other abused children.
