Maternal responsiveness and maternal selectivity in domestic sheep and goats: the two facets of maternal attachment.

Sheep and goats rapidly establish an exclusive relationship with their neonate following contact with it during a sensitive period of maternal responsiveness induced by the physiological events occurring at parturition. The data concerning the sensory, physiological, and neurobiological factors involved in the activation of both maternal responsiveness and the establishment of selective nursing indicates that these processes are activated simultaneously by the combined action of two main factors, the prepartum rise in circulating estrogen and the vaginocervical stimulation (VCS) caused by fetus expulsion. On the one hand, these two factors act on a neural network including the main olfactory system (MOB), the medial preoptic area (MPOA), and the paraventricular nucleus of the hypothalamus (PVN) to induce maternal responsiveness towards any neonate. The intracerebral release of oxytocin (OT) from the PVN, and the triggering of olfactory attraction for amniotic fluid (AF) are key elements in this process. On the other hand, VCS at birth also sets the MOB ready to memorize the individual odor of the neonate, through the release of peptides and neurotransmitters (noradrenaline and acetylcholine). In addition to the MOB, the network involved in recognition mainly includes the medial and cortical amygdala. Across consolidation processes, reorganization occurs in the network engaged in lamb recognition. Whether this memorization may be potentiated by other sensory cues is not known. The identification of the chemosensory compounds involved in the attraction for AF and in the recognition of the neonate is important for understanding the mechanisms of maternal attachment.

Attachment as the basis of psychopathological development and residential treatment.

There seems to be an as yet unresolved question as to whether attachment behavior is an innate factor or whether it is an outcome of primary social relations. On the basis of Bowlby's researches as well as on Emde's, the author argues that attachment is an innate developmental factor that needs external impact, meaning parental care, to evolve and develop. The two cases presented here reflect similar expressions of alienation and detachment as well as essential differences. In the first case, the child has lost his innate ability and urge for social attachment due to severely defective care during early infancy, mainly desertion. In the second case, the child expresses clear attachment ability, yet, due to the deviant care, this ability has developed into disturbed attachment patterns. In both cases, it is claimed that only comprehensive treatment, which is in a way removed from reality, may "rekindle" the innate attachment ability of the first child and lead the second child to unimpaired attachment behavior.

Child-mother attachment and the self in six-year-olds.

Bowlby has proposed that child-parent attachment is important in the child's representation of self. In this study, the child's representation of self was examined in connection with child-mother attachment in a sample of 52 white, middle-class 6-year-olds. Children were seen in 2 play sessions, 1 month apart. Quality of attachment was assessed in each session based on the child's behavior on reunion following a laboratory separation of approximately 1 hour, using a system devised by Main and Cassidy. Aggregated attachment ratings and classifications were assigned based on the child's behavior in both reunions. Assessments of the self consisted of (a) assessment of the self within the relationship with the attachment figure (an incomplete doll stories procedure), (b) assessment of the child's perceptions of how an unspecified "other" views him or her (a puppet interview), (c) direct assessment of global self-esteem independent of the attachment relationship (the subscale of global self-esteem from Harter's Perceived Competence Scale for Children), (d) a second direct assessment of global self-esteem (an interview with the child), and (e) assessment of feelings of competence and acceptance in specific domains that may be precursors of self-esteem (Harter's Scale of Perceived Competence and Social Acceptance for Young Children). Significant, albeit modest, connections between attachment and the self were established; furthermore, specific patterns of self-perceptions were related to particular patterns of attachment.

Adult attachment, love styles, and self-defeating personality characteristics.

The present research showed for 79 men and 79 women that people with more characteristics of the proposed self-defeating personality diagnosis had less secure adult attachments. In addition, self-defeating women described their style of loving as game playing and being less romantically involved. Both men and women who were more self-defeating, once in a relationship, reported feeling dependent, jealous, and desperate to maintain it. These results are consistent with the 1993 findings of Williams and Schill that people with more self-defeating characteristics were more likely to lack secure attachments with parents.

[Attachment representation and a projective test with pictures of parent-child interaction].

The purpose of this study was to assess individual differences in attachment representation. They were assessed, not through direct verbal reports, but indirectly as indicated in a projective test. The test required subjects to tell their impressions of pictures, which depicted daily, routine parent-child interactions. A series of pictures were developed for story-making task, which was named PARS (Picture Attachment Related Study). Three hundred and two (302) undergraduate and vocational students were asked to see the pictures, and freely imagine the situation, think what they would feel, and create the further story. They were then to recall their own experiences with their parents, and fill out a questionnaire of how they see their relationship with others. It was found that those who made a trustful PARS story recalled their own attachment experiences in an autonomous way, and had lower distrust in their relationship with others. Thus, results of the projective test were shown to reflect individual personal attachment experiences, and the test be useful.

[Effects of believes and expectations about self and others on emotional recognition of facial expressions: from the perspective of adult attachment].

This study aimed at examining how adult attachment styles as believes and expectations about self and others affected emotional recognition of facial expressions. In this study, hypotheses were framed based on the perspective of attachment dimensions. One hundred and sixty one undergraduates observed positive, negative, and neutral facial expressions as stimulus, and rated the extent to which each stimuli expressed several kinds of emotion. The main results were as follows. Generally, either anxious or avoidant individuals were less likely to perceive positive emotion (happy) from facial expressions, and anxious and less avoidant individuals perceived other-oriented negative emotions (anger, disgust, and contempt). In addition, avoidant individuals were less likely to perceive positive emotion from positive facial expressions. On the other hand, from negative facial expressions, anxious and less avoidant individuals were more likely to perceive other-oriented negative emotions, and anxious individuals were less likely to perceive positive emotion. The results were discussed from the perspective of adult attachment theory.

[Study on the infinity optical thickness of light-cured composite resins and attached shade guides].

OBJECTIVE: This study compared the opaque characteristics of light-cured composite resins and attached shade guides. METHODS: Three kinds of light-cured composite resins and attached shads guides were used. A plastic mold (10mm in diameter and 4mm in height) was used to prepare disk specimens. Color was measured by CIE L*a*b* relative to CIE source against a white and a black background, using a colorimeter. Color change (DeltaE)was calculated as DeltaE=[(DeltaL*)(2)+(Deltaa*)(2)+(Deltab*)(2)](1/2). The heights of composite resins were recorded as DeltaE is approximately 1.5. The infinity optical thickness of composite resins when delta E*=1.5 was calculated by regression formulation. RESULTS: There was significant difference in color difference and the infinity optical thickness among materials and shades. The infinity optical thickness gradual decreased in the same shade mark from 1 to 4, and from A to D the results was not simple. CONCLUSION: There was significant difference in the infinity optical thickness between the attached shade guides and the resins materials. Composite resins contain micro-filler were inferior in infinity optical thickness.

The attachments of children in foster care.

Subjects for this research were 52 foster children (mean ages 7 years, 11 months) and their natural and foster parents. Case history files provided information concerning reasons for placing the children in foster care. Foster parents completed the Parent/Child Reunion Inventory (Marcus, 1988) measuring the "quality of reunion behavior" following separation. Foster mothers also completed the Child Behavior Checklist (Achenbach & Edelbrock, 1983), and measures of adult empathy were collected from both foster parents. Foster care workers rated the quality and intensity of attachment between the child and all parents. Finally, foster children were interviewed concerning their social supports, perception of affection from adults, and the quality of their relationships with adults and friends. Results showed that behavior and school achievement problems were predictable from measures of the quality of attachment with parents. The mean number of behavior problems of foster children were found to be midway between clinical and nonclinical norm groups. Children's perceptions of friends' behavior and degree of control over friends were related to their adjustment. Case history variables were also related to behavior problems and attachment.

Temperament and attachment security in the strange situation: an empirical rapprochement.

In response to Frodi and Thompson's recent demonstration that infants classified A1-B2 in the Strange Situation differ significantly in emotional expression from infants classified B3-C2, several longitudinal data sets were examined to determine whether these group differences might be a function of infant temperament. Data from 3 separate samples revealed significant concordance between infant-mother and infant-father Strange Situation classifications when scored in terms of A1-B2 versus B3-C2, but not when scored in terms of the traditional A-B-C system. In addition, in 2 samples on which newborn behavioral data were available, A1-B2 infants displayed more autonomic stability than B3-C2 infants, and in one of the samples the former infants were more alert and positively responsive as newborns (with means in the same direction in Sample 2). Moreover, mothers of A1-B2 infants described their babies as less difficult to care for at 3 months of age. Considered together, these findings suggest that infant temperament affects the manner in which security or insecurity is expressed rather than whether or not the infant develops a secure or insecure attachment. These findings are discussed in terms of their implications for the study of the interactional antecedents and the developmental consequences of attachment security.
