Application of The APA Practice Guidelines on Suicide to Clinical Practice

This article presents charts from The American Psychiatric Association Practice Guideline for the Assessment and Treatment of Patients with Suicidal Behaviors, part of the Practice Guidelines for the Treatment of Psychiatric Disorders Compendium, and a summary of the assessment information in a format that can be used in routine clinical practice. Four steps in the assessment process are presented: the use of a thorough psychiatric examination to obtain information about the patient's current presentation, history, diagnosis, and to recognize suicide risk factors therein; the necessity of asking very specific questions about suicidal ideation, intent, plans, and attempts; the process of making an estimation of the patient's level of suicide risk is explained; and the use of modifiable risk and protective factors as the basis for treatment planning is demonstrated. Case reports are used to clarify use of each step in this process.     

Romantic love and sexual desire in close relationships

Drawing on recent claims in the study of relationships, attachment, and emotion, the authors hypothesized that romantic love serves a commitment-related function and sexual desire a reproduction-related function. Consistent with these claims, in Study 1, brief experiences of romantic love and sexual desire observed in a 3-min interaction between romantic partners were related to distinct feeling states, distinct nonverbal displays, and commitment- and reproductive-related relationship outcomes, respectively. In Study 2, the nonverbal display of romantic love was related to the release of oxytocin. Discussion focuses on the place of romantic love and sexual desire in the literature on emotion.     

Implicit memory for novel conceptual associations in amnesia

In two experiments, we evaluated the status of implicit memory for novel associations in amnesia. Experiment 1 assessed priming in a category exemplar generation task in which contextual information associated with a target could increase the likelihood of target generation. Control participants, but not amnesic patients, showed associative priming. Amnesics’ impairment was not due to the use of explicit memory by control subjects but reflected a genuine impairment in implicit memory for novel conceptual associations. Experiment 2 assessed priming in a relatedness judgment task, in which associative priming was manifest as longer latencies for old than for recombined pairs of unrelated words. Amnesic patients showed intact associative priming in this task. We discuss differences in the status of implicit memory for novel conceptual associations in amnesia, with reference to the nature of the representation that supports priming in the two tasks and the type of processing that is required at test.     

Mutually responsive orientation between parents and their young children: toward methodological advances in the science of relationships

The authors captured mother-child and father-child relationships when children were 7 and 15 months old by coding 4 explicitly dyadic components of mutually responsive orientation (MRO): coordinated routines, harmonious communication, mutual cooperation, and emotional ambiance. These components were coded in 102 families in naturalistic contexts at home and in the laboratory. Using confirmatory factor analytic methods, the authors demonstrated that MRO (a) is a unidimensional latent construct, (b) can be distinguished from and is not reducible to the 2 interacting individuals' qualities (responsiveness and positive affect), and (c) has remarkable measurement equivalence from ages 7 to 15 months for both mother-child and father-child relationships and has remarkable measurement equivalence across both parent-child relationships at both child ages. This study represents an effort to advance the science of relationships by moving away from individual-based measures to dyadic measures and by using contemporary data analytic strategies.     

Sex differences in stress generation: an examination of sociotropy/autonomy, stress, and depressive symptoms

Hammen (1991) proposed that both individual characteristics and depressive symptomatology may explain the stress generation process, in which individuals contribute, in part, to a more stressful environment for themselves. Nonetheless, research has not teased apart the impact of vulnerability factors and depressive symptomatology on this process. Ninety-nine college students, selected to be variable on personality vulnerabilities of sociotropy and autonomy, were followed for 6 weeks. Weekly depressive symptoms and stressful life events that were likely caused in part by the individual (dependent stress) were assessed. Multilevel modeling results indicated that prior-week depressive symptoms significantly predicted current-week dependent interpersonal stress levels. A significant sex-by-sociotropy effect emerged such that being female and scoring high on sociotropy predicted higher levels of dependent interpersonal stress. This interpersonal stress generation effect for women partially mediated the relationship between sociotropy and depressive symptoms.     

Connectivity among semantic associates: an fMRI study of semantic priming

Semantic priming refers to a reduction in the reaction time to identify or make a judgment about a stimulus that has been immediately preceded by a semantically related word or picture and is thought to result from a partial overlap in the semantic associates of the two words. A semantic priming lexical decision task using spoken words was presented in event-related fMRI and behavioral paradigms. Word pairs varied in terms of semantic relatedness and the connectivity between associates. Thirteen right-handed subjects underwent fMRI imaging and 10 additional subjects were tested in a behavioral version of the semantic priming task. It was hypothesized priming would be greatest, reaction time fastest, and cortical activation reduced the most for related word pairs of high connectivity, followed by related word pairs of low connectivity, and then by unrelated word pairs. Behavioral and fMRI results confirmed these predictions. fMRI activity located primarily in bilateral posterior superior and middle temporal regions showed modulation by connectivity and relatedness. The results suggest that these regions are involved in semantic processing.
