The Developmental Roots of Borderline Personality Disorder in Early Attachment Relationships: A Theory and Some Evidence

The paper suggests a way of understanding borderline personality disorder in terms of the failure of a secure base. We begin with an account of optimal self-development in a secure attachment context, highlighting the importance of the caregiver's ability to help the small child think about his own and others' minds. This optimal self-development is crucial in developing the child's capacity for mentalization, which can enhance his resilience in the face of later trauma. We discuss the impact of attachment trauma in later development, arguing that the extent of this impact depends on how well early attachment relationships facilitated the capacity for mentalization. We identify some of the consequences for the representations of the internal world of a failure of mentalization that may follow trauma in individuals made vulnerable by genetic predisposition or disorganized early attachment. We link these features to the clinical presentation associated with borderline personality organization. Finally, some of the necessary characteristics of successful psychotherapeutic treatment of borderline personality disorder are briefly considered.     

The Embodiment Thesis

In this essay I articulate and defend a thesis about the nature of morality called “the embodiment thesis”. The embodiment thesis states that moral values underdetermine the obligations and entitlements of individual persons, and that actual social institutions must embody morality by specifying these moral relations. I begin by presenting two thought experiments that elucidate and motivate the embodiment thesis. I then proceed by distinguishing the embodiment thesis from a Rawlsian doctrine about the nature of justice, from the doctrine of moral relativism, and from solutions to the coordination problem of rational choice theory.     

Cross-modal links in exogenous covert spatial orienting between touch, audition, and vision

Three experiments investigated cross-modal links between touch, audition, and vision in the control of covert exogenous orienting. In the first two experiments, participants made speeded discrimination responses (continuous vs. pulsed) for tactile targets presented randomly to the index finger of either hand. Targets were preceded at a variable stimulus onset asynchrony (150,200, or 300 msec) by a spatially uninformative cue that was either auditory (Experiment 1) or visual (Experiment 2) on the same or opposite side as the tactile target. Tactile discriminations were more rapid and accurate when cue and target occurred on the same side, revealing cross-modal covert orienting. In Experiment 3, spatially uninformative tactile cues were presented prior to randomly intermingled auditory and visual targets requiring an elevation discrimination response (up vs. down). Responses were significantly faster for targets in both modalities when presented ipsilateral to the tactile cue. These findings demonstrate that the peripheral presentation of spatially uninforrnative auditory and visual cues produces cross-modal orienting that affects touch, and that tactile cues can also produce cross-modal covert orienting that affects audition and vision.     

Auditory and audiovisual inhibition of return

Two experiments examined any inhibition-of-return (IOR) effects from auditory cues and from preceding auditory targets upon reaction times (RTs) for detecting subsequent auditory targets. Auditory RT was delayed if the preceding auditory cue was on the same side as the target, but was unaffected by the location of the auditorytarget from the preceding trial, suggesting that response inhibition for the cue may have produced its effects. By contrast, visual detection RT was inhibited by the ipsilateral presentation of a visual target on the preceding trial. In a third experiment, targets could be unpredictably auditory or visual, and no peripheral cues intervened. Both auditory and visual detection RTs were now delayed following an ipsilateral versus contralateral target in either modality on the preceding trial, even when eye position was monitored to ensure central fixation throughout. These data suggest that auditory target—target IOR arises only when target modality is unpredictable. They also provide the first unequivocal evidence for cross-modal IOR, since, unlike other recent studies (e.g., Reuter-Lorenz, Jha, & Rosenquist, 1996; Tassinari & Berlucchi, 1995; Tassinari & Campara, 1996), the present cross-modal effects cannot be explained in terms of response inhibition for the cue. The results are discussed in relation to neurophysiological studies and audiovisual links in saccade programming.     

Children like dense neighborhoods: Orthographic neighborhood density effects in novel readers

Previous evidence with English beginning readers suggests that some orthographic effects, such as the orthographic neighborhood density effects, could be stronger for children than for adults. Particularly, children respond more accurately to words with many orthographic neighbors than to words with few neighbors. The magnitude of the effects for children is much higher than for adults, and some researchers have proposed that these effects could be progressively modulated according to reading expertise. The present paper explores in depth how children from 1st to 6th grade perform a lexical decision with words that are from dense or sparse orthographic neighborhoods, attending not only to accuracy measures, but also to response latencies, through a computer-controlled task. Our results reveal that children (like adults) show clear neighborhood density effects, and that these effects do not seem to depend on reading expertise. Contrarily to previous claims, the present work shows that orthographic neighborhood effects are not progressively modulated by reading skill. Further, these data strongly support the idea of a general language-independent preference for using the lexical route instead of grapheme-to-phoneme conversions, even in beginning readers. The implications of these results for developmental models in reading and for models in visual word recognition and orthographic encoding are discussed.     

Are high school students accurate or clueless in estimating substance use among peers?

The purpose of this study was to assess adolescents' estimations of the prevalence of alcohol and other drug use and to examine the consistency between these estimations and reported use. A survey was administered to 223 students in three northwestern U.S. high schools. Results showed that students in each of the three high schools grossly overestimated the prevalence of substance use when compared to self-reports of use. Still, students were not entirely clueless about the relative normativeness of substance use when comparing estimates and rates of use among the three schools. The school with the highest estimated prevalence of a particular substance use behavior generally also had the highest self-reported use of that same substance. These findings imply the need for high school personnel to provide students with accurate information about the actual prevalence of substance use within each school.     

The effect of sensitization and coping style on post-traumatic stress symptoms and quality of life: two longitudinal studies

The present study investigated the effects of multiple trauma exposure and coping style on post-traumatic stress symptoms and quality of life. It was hypothesized that sensitization would occur in subjects repeatedly exposed to life-threatening situations (study 1), and different coping styles would act as a resilience or facilitating factor in symptom development (study 2). The results showed that the single-exposure group revealed a decrease in trauma specific stress reactions from three weeks to four months, with a persistent reduction at 12-month follow-up, while the repeated-exposure group showed an increase in symptom reporting over the 12-month period. The same pattern emerged for perceived quality of life-measured by the General Health Questionnaire (GHQ-30). The second study revealed a correlation between scores on avoidant-focused coping style and the Impact of Event Scale-avoidance dimension, Post-traumatic Symptom Scale and GHQ-30. Furthermore, only subjects with a dominant coping style of emotion-focused or task-focused coping showed a reduction in trauma-specific symptom scores over time.
