Rejection Sensitivity and Executive Control: Joint predictors of Borderline Personality features

Two studies tested the hypothesis that rejection sensitivity (RS) and executive control (EC) jointly predict borderline personality (BP) features. We expected high RS to be related to increased vulnerability for BP features specifically in people who also had difficulties in executive control (EC). Study 1 tested this hypothesis using a sample of college students (N = 379) whereas Study 2 (N = 104) was conducted using a community sample of adults. Both studies operationalized EC by a self-report measure. For a subsample in Study 2 (N = 80), ability to delay gratification at age 4 was also used as an early behavioral precursor of EC in adulthood. In both studies, high RS was associated with increased BP features among people low in self-reported EC. Among those high in self-reported EC, the relationship between RS and BP features was attenuated. Study 2 found parallel findings using preschool delay ability as a behavioral index of EC. These findings suggest that EC may protect high RS people against BP features.     

Examining the relation between borderline personality features and social support: The mediating role of rejection sensitivity

Potential mechanisms underlying the pathway between borderline personality features and indices of social support have yet to be elaborated, despite that social difficulties are a hallmark feature of borderline personality disorder (BPD). We hypothesized that rejection sensitivity, or the tendency to anxiously anticipate and readily perceive social rejection, might be one mechanism leading to the negative social impact associated with BPD symptoms. To test this hypothesis, a sample of college students (N = 165) completed self-report measures in the laboratory. With rejection sensitivity in the model, borderline features did not directly predict number of social supports. However, borderline features indirectly predicted decreased number of social supports via increased rejection sensitivity. Conversely, borderline features directly predicted social support satisfaction but did not evidence an indirect effect through rejection sensitivity. The results of this research suggest that rejection sensitivity is an important individual difference by which borderline features leads to the lower levels of social support demonstrated in past research. Future directions, such as examining potential mediators of social support perception, are discussed.     

Rejection sensitivity as a mediator of the relationship between experienced rejection and borderline characteristics

Experiences of rejection in childhood play an important role in the etiology of borderline personality disorder (BPD). Additionally, individuals who report borderline symptoms report high levels of rejection sensitivity. The current study aimed to disentangle the relationship between experiences of rejection, rejection sensitivity and borderline characteristics. Therefore, we retrospectively assessed experiences of parental and peer rejection, collected data of self-reported rejection sensitivity and social support and prospectively investigated borderline characteristics in a sample of 193 students. Results indicated that rejection sensitivity fully mediated the previously significant relationship between experiences of parental rejection and borderline characteristics, whereas peer rejection maintained a significant effect on borderline traits. Social support was identified as a protective factor. Results indicated a crucial role of rejection sensitivity in borderline symptomatology.     

Effects of anxiety and attention control on processing pictorial and linguistic emotional information

This study investigated the role of executive attention control in modulating selective processing of emotional information in anxiety. It was hypothesized that the combination of high anxiety and poor attention control would be associated with greater difficulty in ignoring task-irrelevant threat-related information. The study included both faces and words as stimuli. Cognitive interference effects were assessed using two emotional Stroop tasks: one with angry, fearful, happy and neutral faces, and one with threat-related, positive, and neutral words. An objective measure of attention control was obtained from the Attention network task. There were four participant groups with high/low trait anxiety and high/low attention control. Results indicated that the combination of high anxiety and poor attention control was associated with greater cognitive interference by emotional faces (including angry faces), compared to neutral faces. This interference effect was not evident in participants with high anxiety and high attentional control, or in low-anxious individuals. There was no evidence of associations between anxiety, attention control, and the interference effect of emotional words. Results indicate that high anxiety and poor attention control together predict enhanced processing of emotionally salient information, such as angry facial expressions. Implications for models of emotion processing are discussed.     

Attenuation of attention bias in obsessive-compulsive disorder

Cognitive theories of obsessive-compulsive disorder (OCD) suggest that the disorder is characterized by an attention bias towards personally relevant threatening material. However, existing research on attention bias in OCD has yielded conflicting findings. One possibility that might account for the null findings is that attention bias may diminish over the course of the experiment. The present study tested this hypothesis using a visual dot-probe task with idiographic word selection. Results from our study confirmed that individuals with OC symptoms show an attention bias towards idiographically selected, threatening information in the first block of trials, and that the degree of this bias is correlated with the severity of OC symptoms. The temporal pattern of attention bias over the course of the experiment was consistent with our hypothesis. A comparison of early and late blocks of trials revealed an attenuation of attention bias in individuals with OC symptoms, potentially reflecting habituation to threatening information over the course of the experiment.     

The social problem-solving abilities of people with borderline personality disorder

Interventions for people suffering from borderline personality disorder (BPD), such as dialectical behaviour therapy, often include a problem-solving component. However, there is an absence of published studies examining the problem-solving abilities of this client group. In this study, the social problem-solving (SPS) abilities of three groups of participants were assessed: a BPD group (n=25), a clinical control (CC) group (n=25) procedure and a non-clinical control (NCC) group (n=25). SPS ability was assessed using the means-end problem-solving (MEPS) procedure and the Social Problem-Solving Inventory-Revised (SPSI-R). The BPD group exhibited deficits in their SPS abilities, however the majority of these deficits were not specific to the BPD group but were also found in the CC group, indicating that a common factor between these two groups, such as negative affect, may account for these observed deficits. Specific SPS deficits were identified in the BPD group: they provided less specific solutions on the MEPS and reported higher levels of negative problem orientation and a more impulsive/carelessness style towards solving social problems. The results of this study provide empirical support for the use of problem-solving interventions with people suffering from BPD.     

Alterations of social attention in mental disorders: Phenomenology,scope, and future directions for research

Mental disorders often involve changes in the way subjects attend to other people. However, the nature of these modifications and how they unfold in different pathologies are not sufficiently clear. This article addresses these issues from the perspective of phenomenological psychopathology. The primary goal of the article is to suggest a new way of assessing and distinguishing the alterations of social attention in subjects with mental disorders. The first part of the article characterizes the essential properties of a capacity for social attention based on multidisciplinary evidence. This model is then used to examine anomalies in social attention in autism, schizophrenia, borderline personality disorder, and social anxiety disorder. The analysis of alterations in the way subjects with different types of pathologies attend to and with others is followed by a threefold typology, which clarifies the phenomenal nature of impairments of social attention in mental disorders.     

Hypervigilance in patients with borderline personality disorder: specificity, automaticity, and predictors

According to cognitive theory, an important factor in borderline personality disorder (BPD) is hypervigilance. The aim of the present study was to test whether BPD patients show schema-related biases, and to explore relations with childhood trauma, schemas, and BPD symptoms. Sixteen BPD patients were compared with 18 patients with a cluster C personality disorder, 16 patients with an axis I disorder, and 16 normal controls. An emotional Stroop task was applied with schema-related and unrelated, negative and positive, supra- and subliminal person-related stimuli. BPD patients showed hypervigilance for both negative and positive cues, but were specifically biased towards schema-related negative cues. Predictors were BPD schemas, childhood sexual traumas, and BPD anxiety symptoms. Both BPD and axis I disorder patients showed a trend for a bias for negative schema-related subliminal stimuli. More attention to hypervigilance in BPD is recommended for clinical practice.     

The impact of threat and cognitive stress on speech motor control in people who stutter

PurposeIn the present study, an Emotional Stroop and Classical Stroop task were used to separate the effect of threat content and cognitive stress from the phonetic features of words on motor preparation and execution processes.MethodA group of 10 people who stutter (PWS) and 10 matched people who do not stutter (PNS) repeated colour names for threat content words and neutral words, as well as for traditional Stroop stimuli. Data collection included speech acoustics and movement data from upper lip and lower lip using 3D EMA.ResultsPWS in both tasks were slower to respond and showed smaller upper lip movement ranges than PNS. For the Emotional Stroop task only, PWS were found to show larger inter-lip phase differences compared to PNS. General threat words were executed with faster lower lip movements (larger range and shorter duration) in both groups, but only PWS showed a change in upper lip movements. For stutter specific threat words, both groups showed a more variable lip coordination pattern, but only PWS showed a delay in reaction time compared to neutral words. Individual stuttered words showed no effects. Both groups showed a classical Stroop interference effect in reaction time but no changes in motor variables.ConclusionThis study shows differential motor responses in PWS compared to controls for specific threat words. Cognitive stress was not found to affect stuttering individuals differently than controls or that its impact spreads to motor execution processes.Educational objectives: After reading this article, the reader will be able to: (1) discuss the importance of understanding how threat content influences speech motor control in people who stutter and non-stuttering speakers; (2) discuss the need to use tasks like the Emotional Stroop and Regular Stroop to separate phonetic (word-bound) based impact on fluency from other factors in people who stutter; and (3) describe the role of anxiety and cognitive stress on speech motor processes.     

Loneliness,HPA stress reactivity and social threat sensitivity: Analyzing naturalistic social challenges

Loneliness has been linked to poor health through an increased activation of threat surveillance mechanisms, such as the hypothalamic‐pituitary‐adrenal axis (HPA ). The socio‐cognitive model (Cacioppo & Hawley) proposes that lonely people have an increased social threat sensitivity which activates the HPA axis. The current study examined the impact of loneliness on HPA stress reactivity and social threat sensitivity in response to naturally occurring social challenges. Participants (N = 45) were prospective undergraduates attending a 3‐day university preparation programme over the summer, prior to commencing their university studies. Cortisol levels and perceived stress were measured before and after an ice breaker session on Day 1 and a lecture session on Day 3. Social threat sensitivity was also measured on the first and third day. When meeting unfamiliar peers in the ice breaker session, HPA stress reactivity was evident, but it was not markedly different in those who reported high levels of loneliness than those with low levels. The high loneliness group had higher levels of perceived stress and increased social threat sensitivity than the low loneliness group on both testing days. The findings show partial support for the socio‐cognitive model of loneliness because increased threat sensitivity was demonstrated in the high loneliness group. The findings indicate that lonely people do not respond in a physiologically different way to specific social challenges, but they typically report higher social threat sensitivity and higher perceived stress than their non‐lonely peers.     

Simultaneous attentional guidance by working-memory and selection history reveals two distinct sources of attention

Recent theories of attention have proposed that selection history is a separate, dissociable source of information that influences attention. The current study sought to investigate the simultaneous involvement of selection history and working-memory on attention during visual search. Experiments 1 and 2 used target feature probability to manipulate selection history and found significant effects of both working-memory and selection history, although working-memory dominated selection history when they cued different locations. Experiment 3 eliminated the contribution of voluntary refreshing of working-memory and replicated the main effects, although selection history became dominant. Using the same methodology, but with reduced probability cue validity, both effects were present in Experiment 4 and did not significantly differ in their contribution to attention. Effects of selection history and working-memory never interacted. These results suggest that selection history and working-memory are separate influences on attention and have little impact on each other. Theoretical implications for models of attention are discussed.     

Comparison of different strategies to decrease negative affect and increase positive affect in women with borderline personality disorder

Background

In this study we compared the effect of different emotion regulation strategies on positive and negative emotions in patients with borderline personality disorder.

Methods

Emotion regulation strategies were a distracting task, individual positive memory imagery, individual soothing imagery, and a neutral comparison condition. During two separate sessions, 17 participants watched either neutral or negative movie segments before using these strategies.

Results

All three strategies influenced emotions into a favorable direction as compared to the neutral comparison condition. The positive memory image increased positive emotions significantly stronger than counting colors and distracting.

Discussion

Different strategies seem to have similar effects in decreasing negative emotions. Positive emotions may be affected in particular by positive and soothing imagery techniques.     

Personal and appearance-based rejection sensitivity in body dysmorphic disorder

Although rejection sensitivity may be an important feature of body dysmorphic disorder (BDD), no studies have examined rejection sensitivity in a clinical sample and compared types of rejection sensitivity in individuals with BDD. Personal and appearance-based rejection sensitivity scores in forty-six patients diagnosed with BDD were compared with published norms. Associations between rejection sensitivity, BDD severity, and other clinical variables were examined. Personal and appearance-based rejection sensitivity scores were 0.6 and 1.1 standard deviation units above published norms, respectively. Greater personal rejection sensitivity was associated with more severe BDD and depressive symptoms, poorer mental health, general health, and physical and social functioning. Greater appearance-based rejection sensitivity was associated with more severe BDD and depressive symptoms, and poorer general health. Appearance-based rejection sensitivity contributed more unique variance to BDD severity than personal rejection sensitivity did; however, personal rejection sensitivity contributed more unique variance to general health than appearance-based rejection sensitivity did.     

Explicit and implicit shame aversion predict symptoms of avoidant and borderline personality disorders

Research on the connections between shame and personality disorders (PDs) has focused predominantly on shame proneness. We examined the relationships of shame aversion, or experiencing shame as painful and unbearable, with avoidant and borderline personality disorders. Participants completed self-report measures assessing avoidant and borderline PDs, shame aversion, shame proneness and general experiential avoidance, as well as the recently developed questionnaire-based implicit association test that assessed shame aversion. Self-reported and implicit shame aversion correlated with both PDs, and hierarchical regression models showed that shame aversion incrementally predicted these PDs over and above shame proneness and general experiential avoidance. These findings suggest that individuals who perceive shame as particularly aversive tend to resort to maladaptive behavioral patterns that may impair personality functioning.     

Associations Between Symptoms of Borderline Personality Disorder,Externalizing Disorders,and Suicide-Related Behaviors

Borderline personality disorder and externalizing disorders are associated with suicide-related behaviors. The present study examined whether symptoms of borderline personality disorder mediate the relationship between externalizing disorders and suicide-related behaviors. Diagnostic interviews were administered to 344 participants (n = 233 women). Results indicated that symptoms of antisocial personality disorder, alcohol use disorders, and drug use disorders each were significantly associated with suicide threats and self-injurious behavior in women and symptoms of antisocial personality disorder were associated with suicide attempts in women. With the exception of the association between symptoms of alcohol dependence and self-injurious behaviors, borderline personality disorder symptoms mediated or partially mediated all associations between externalizing disorders and suicide-related behaviors in women. These results highlight the importance of assessment and treatment of borderline personality disorder symptoms in individuals with externalizing disorders, particularly in the presence of suicide-related behaviors.

Feeling guilty as a source of information about threat and performance

OCD patients experience increased feelings of guilt, threat and uncertainty about harm prevention. As to the relation between these phenomena, it was hypothesised that the experience of guilt acts as "information" that increases the sense of threat and decreases the sense that preventive action is effective. We tested whether state guilt is used as information about risk and prevention effects and whether people high in trait guilt do so more than others. Participants high and low in trait guilt were included. Three types of affect were experimentally induced: guilt, anxiety and a neutral affect. Then, participants estimated the likelihood and severity of a negative outcome, and the dissatisfaction with preventive performances in two OCD relevant scenarios. Relative to low-trait guilt participants, people high in trait guilt had higher ratings of risk after induction of state guilt. With regards to dissatisfaction with preventive performance, there was only a trend for high-trait guilt participants to respond stronger to state guilt. The results suggest that people with a general inclination to feel guilty use temporary feelings of guilt as information about the threat content of a situation and do so even if the source of state guilt is unrelated to the situation. Implications for the understanding of OCD are discussed.     

Testing the dorsal stream attention hypothesis: Electrophysiological correlates and the effects of ventral stream damage

The roles of dorsal and ventral processing streams in visual orienting and conscious perception were examined in two experiments. The first employed high density EEG with source localization. The second comprised a neuropsychological case study. Visual orienting was assessed with an attention procedure, where peripheral letters cued participants towards a target location. In the perception procedure participants responded to the same letters by performing an explicit conscious discrimination. In Experiment 1, the peripheral letters elicited rapid dorsal stream activation in the attention procedure, and this activation preceded top-down enhancement of target processing in occipital cortex. In the perception procedure early ventral stream activation was seen. In addition, peripheral letters elicited an “early directing attention negativity” (EDAN) over parietal recording sites in the attention procedure, but not in the perception procedure. In Experiment 2, a patient with a bilateral ventral stream lesion but preserved dorsal stream function showed clear disruption to performance in the perception procedure, whilst exhibiting a normal visual orienting effect in the attention procedure. Taken together these findings (1) highlight the distinct roles of the dorsal and ventral streams in attention and perception, and (2) suggest how these streams might interact, via reentrant effects of attention on perceptual processing.     

Perception of speech and nonspeech stimuli by children with and without reading disability and attention deficit hyperactivity disorder

The auditory temporal deficit hypothesis predicts that children with reading disability (RD) will exhibit deficits in the perception of speech and nonspeech acoustic stimuli in discrimination and temporal ordering tasks when the interstimulus interval (ISI) is short. Initial studies testing this hypothesis did not account for the potential presence of attention deficit hyperactivity disorder (ADHD). Temporal order judgment and discrimination tasks were administered to children with (1) RD/no-ADHD (n=38), (2) ADHD (n=29), (3) RD and ADHD (RD/ADHD; n=32), and (4) no impairment (NI; n=43). Contrary to predictions, children with RD showed no specific sensitivity to ISI and performed worse relative to children without RD on speech but not nonspeech tasks. Relationships between perceptual tasks and phonological processing measures were stronger and more consistent for speech than nonspeech stimuli. These results were independent of the presence of ADHD and suggest that children with RD have a deficit in phoneme perception that correlates with reading and phonological processing ability.

Attentional modulation of visual-evoked potentials by threat: investigating the effect of evolutionary relevance

In dot-probe tasks, threatening cues facilitate attention to targets and enhance the amplitude of the target P1 peak of the visual-evoked potential. While theories have suggested that evolutionarily relevant threats should obtain preferential neural processing, this has not been examined empirically. In this study we examined the effects of evolutionarily relevant (e.g. spiders and snakes) and irrelevant (e.g. knifes and syringes) threatening cues. Non-predictive threatening cues (in left or right visual field) were paired with non-threatening cues and were followed by neutral targets in the same or opposite location. The amplitude of the target P1 was increased in contralateral electrodes when the target followed in the same location as the threatening cues. This effect did not interact with evolutionary relevance. Both evolutionary relevant and evolutionary irrelevant threats led to increased P1 amplitude, although the effect was stronger for modern threats. We conclude that the threat-superiority effect is robust and largely independent of the type of threatening stimulus.
