Suicidal behavior in chemically dependent adolescents

Among 250 adolescents in a short-term residential treatment program for chemical dependency, 20% had attempted suicide in the two years prior to admission. Females, however, were found to have a higher attempt rate than did males. Suicide attempters were compared with a group of 50 nonsuicidal adolescents from the same treatment program and 50 non-chemically dependent, nonsuicidal high school students. Each adolescent was administered the Symptom Checklist 90-Revised (SCL-90-R), and a biographical history was obtained. The suicidal group was found to be more psychologically distressed than were the other two groups. Post hoc analysis revealed that there were significant differences between the chemically dependent groups (suicidal, nonsuicidal) on the Global Severity Index of the SCL-90-R, as well as the following subscales: Somatization, Depression, Anxiety, and Phobic Anxiety. It was also found that the majority of suicidal gestures or attempts had gone untreated beyond medical management. It was found that only 28% of the suicide attempters had received crisis intervention or emergency room treatment, and only 27% had received some type of follow-up treatment or counseling. These results are discussed, particularly in regard to the issue of "covert suicide."     

Maternal correlates of toddler insecure and dependent behavior

The present study was designed to examine the relationship between characteristics of mothers and their toddler's insecure and dependent behavior. The authors studied 254 2-year-old toddlers and their mothers via a structured questionnaire administered to the mothers in their homes. The extent to which insecure and dependent behavior is related to the domains of maternal child rearing, maternal personality traits, parental marital relations, and maternal drug use was assessed. Using Pearson correlations and hierarchical multiple regression analyses, the authors found that the maternal child-rearing and maternal personality domains have a direct effect on the toddlers' insecure and dependent behavior. The maternal child-rearing domain also served as a mediator for the domains of the maternal personality attributes, parents' marital relations, and maternal drug use. There also was evidence suggesting an indirect effect of maternal personality attributes on the toddlers' insecure and dependent behavior, which is mediated by the domain of maternal child-rearing practices. Implications for the prevention of insecure and dependent behavior in toddlers are discussed.     

Oral sex as mate retention behavior

Men perform “mate retention” behaviors to reduce the likelihood of their partner’s infidelity. One mate retention strategy men use is to increase their partner’s relationship satisfaction by provisioning her with benefits. We recruited 351 men to investigate whether men perform oral sex on their partner as part of a broader benefit-provisioning mate retention strategy. In support of the predictions, men who reported performing more mate retention behaviors, in general, and more benefit-provisioning mate retention behaviors, in particular, also reported greater interest in and spent more time performing oral sex on their partner. We present limitations of the research and discuss the benefits of an evolutionary perspective for investigating oral sex as a mate retention behavior.     

Childhood trauma and suicidal behavior in male cocaine dependent patients.

A consecutive series of 100 male cocaine dependent patients were interviewed about suicidal behavior and completed the 34-item Childhood Trauma Questionnaire (CTQ) to determine whether childhood trauma is associated with suicidal behavior in cocaine dependent men. Patients who had attempted suicide (n = 34) reported significantly higher scores for childhood emotional abuse, physical abuse, sexual abuse, and emotional and physical neglect than patients who had never attempted suicide (n = 66). In this study, various childhood traumas were found to be significantly associated withsuicidal behavior among adult male cocaine dependent patients.     

Temperature dependence of the plastic flow behavior of tantalum

Nanoindention has been used to study the plastic flow behavior of bcc Ta(001) in the temperature range 25–200°C. Most notably, it is found that the shape of the load–displacement curves changes with increasing temperature. Only one large discontinuity marking the onset of plasticity is observed in room-temperature experiments, whereas multiple pop-ins separated by elastic reloading segments were observed at 200°C. Detailed analysis of the load–displacement curves indicates that the lattice resistance decreases with increasing temperature, consistent with the mobilization of screw dislocations by thermal activation. Contributions from the oxide layer and/or thermal drift can be excluded.     

Programming a randomized dependent group contingency and common stimuli to promote durable behavior change

Low levels of academic engagement may impede students’ acquisition of skills. Intervening on student behavior using group contingencies may be a feasible way to increase academic engagement during group instruction. The current study examined the effect of a randomized dependent group contingency on levels of academic engagement for second‐grade participants receiving small‐group reading and writing instruction. The results showed that a randomized dependent group contingency increased the academic engagement of primary participants and several of the other participants during small‐group instruction. The findings also showed that high levels of academic engagement were maintained when common stimuli were present and the dependent group contingency was withdrawn.     

The relationships among asymmetry in task dependence, perceived helping behavior, and trust

Social relations analyses involving 132 working relationships among 60 individuals from 29 teams revealed that an increase in a team member's task dependence on another team member was associated with higher levels of perceived help from and interpersonal trust in that specific team member, provided the other member was highly task dependent on the focal member. The degree to which an actor perceived a relationship with a partner to be helpful partially mediated the relationship between task dependence and trust. These findings highlight the importance of attending to asymmetries in task dependence and provide valuable insights into mechanisms that can explain the development of trust in organizational work teams.     

Type a behavior,field dependence,and hypervigilance: Toward increased Type A specificity

Field dependence and hypervigilance are two modes of sensory information processing that have been related to cardiovascular functioning. Two studies examined the relationship between these variables and Type A behavior. In both studies, Jenkins Activity Survey-defined Type A and B subjects were assessed for field dependence by the Embedded Figures Test (EFT) and then performed a size estimation task—the measure of hypervigilance. Results indicated that field-dependent Type A's were most hypervigilant. The possible contribution that perceptual style might make to the greater predictive specificity of Type A measures was discussed.Portions of this research were presented at the meeting of the American Psychological Association, Toronto, Canada, August 1984. The authors express their appreciation to Lois Haggard for the design of materials for Study II, and to Rick Smith and Kathy Connell for assistance in conducting Study II.     

Etiologic connections among substance dependence,antisocial behavior,and personality: modeling the externalizing spectrum

A hierarchical biometric model is presented of the origins of comorbidity among substance dependence, antisocial behavior, and a disinhibited personality style. The model posits a spectrum of personality and psychopathology, united by an externalizing factor linked to each phenotype within the spectrum, as well as specific factors that account for distinctions among phenotypes within the spectrum. This model fit self-report and mother-report data from 1,048 male and female 17-year-old twins. The variance of the externalizing factor was mostly genetic, but both genetic and environmental factors accounted for distinctions among phenotypes within the spectrum. These results reconcile evidence for general and specific causal factors within the externalizing spectrum and offer the externalizing factor as a novel target for future research.     

Characteristic interpersonal behavior in dependent and avoidant personality disorder can be observed within very short interaction sequences

We present a behavior observation study of interpersonal behavior in 96 female subjects, who had been screened for the presence of dependent, avoidant, narcissistic and histrionic personality disorder features. Each subject took part in three short role-plays, taken from assertiveness training. Afterwards, both the subject and her role-play partner judged, how assertive the subject had been. Although observation time was very short, dependent and avoidant subjects could be easily identified from their overly submissive behavior in the role-plays. Histrionic and narcissistic subjects did not show distinctive interpersonal behavior. Contrary to a common belief, higher scores on some personality disorder (PD) scales were positively related to cross-situational variability of behavior. Results are discussed with regard to their implications for clinical diagnostics, therapy and the methodology of personality disorder research in general.     

Assimilative behavior identification can also be resource dependent: the unimodel perspective on personal-attribution phases

Three studies examine the role of situational constraint information on behavior identification. It was found that where the behavior-identification task is relatively easy assimilation of the behavior-identification to situational constraints is independent of cognitive load. However, where the behavior-identification task is relatively difficult, assimilation is undermined by load. Given that the discounting of situational constraint information, too, can be independent of load where the dispositional-inference task is easy, and is load-dependent when the task is difficult, it appears that both assimilation and discounting behave identically in regard to load. This conclusion is consistent with the judgmental unimodel whereby behavior identification and dispositional inference differ in the contents of the judgmental questions they address while sharing the underlying process whereby these questions are answered.

The ontology of intentionality I: the dependence ontological account of order: mediate and immediate moments and pieces of dependent and independent objects

This is the first of three essays which use Edmund Husserl's dependence ontology to formulate a non-Diodorean and non-Kantian temporal semantics for two-valued, first-order predicate modal languages suitable for expressing ontologies of experience (like physics and cognitive science). This essay's primary desideratum is to formulate an adequate dependence-ontological account of order. To do so it uses primitive (proper) part and (weak) foundation relations to formulate seven axioms and 28 definitions as a basis for Husserl's dependence ontological theory of relating moments. The essay distinguishes between dependence v. independence, pieces v. moments, mediate v. immediate pieces and moments, maximal v. non-maximal pieces, founded v. unfounded qualities, integrative v. disintegrative dependence, and defines the concepts of the completion of an object, the adumbrational equivalence relation of objects, moments of unity which unify objects, and relating moments which relate objects. The eight theorems [CUT90]-[CUT97] show that relating moments of unity provide an adequate account of order in terms of primitive (proper) part and (weak) foundation relations.
