Temporal dynamics of interference in Simon and Eriksen tasks considered within the context of a dual-process model

Behavioral and brain potential measures were employed to compare interference in Eriksen and Simon tasks. Assuming a dual-process model of interference elicited in speeded response tasks, we hypothesized that only lateralized stimuli in the Simon task induce fast S–R priming via direct unconditional processes, while Eriksen interference effects are induced later via indirect conditional processes. Delays to responses for incongruent trials were indeed larger in the Eriksen than in the Simon task. Only lateralized stimuli in the Simon task elicited early S–R priming, maximal at parietal areas. Incongruent flankers in the Eriksen task elicited interference later, visible as a lateralized N2. Eriksen interference also elicited an additional component (N350), which accounted for the larger behavioral interference effects in the Eriksen task. The findings suggest that interference and its resolution involve different processes for Simon and Eriksen tasks.     

Emotional Skillfulness as a Key Mediator of Aggression

Psychological research has documented several predictors of aggression, including adherence to hegemonic masculinity, trauma symptoms, and insecure attachment. However, at present, little is known about why these variables predict aggression. This study used acceptance theory to introduce the concept of emotional skillfulness as a counterpoint to emotion dysregulation. In an effort to better understand the pathways through which these variables predict aggression, this study used a clinical sample to test three mediational models which hold that emotional skillfulness functions as a common link between the aforementioned predictors and aggression in both men and women. Results indicated that emotional skillfulness is a mediator of aggression for both men and women, but that the predictors of aggression differed by gender.     

The Application of Attachment Theory and Mentalization in Complex Tertiary Structural Dissociation: A Case Study

The concept of structural dissociation can provide useful information for increasingly complex applications of mentalizing in therapeutic settings; however, little integration of the two approaches has emerged. Grounded in the intricate case of a woman diagnosed with dissociative identity disorder, this case study integrates and applies the concepts of structural dissociation and mentalizing from an attachment perspective. Client history includes pervasive spiritual and sexual abuse, as well as extreme neglect throughout her development. The presenting problems, relevant history (including the profound impact of neglect), and the therapeutic models that guided treatment are described. Also presented are the specific therapeutic interventions that have facilitated and strengthened therapeutic alliances, levels of integration, and mentalizing capacity in this challenging but rewarding study of human resiliency.     

The role of intergroup disgust in predicting negative outgroup evaluations

We introduce intergroup disgust as an individual difference and contextual manipulation. As an individual difference, intergroup disgust sensitivity (ITG-DS) represents affect-laden revulsion toward social outgroups, incorporating beliefs in stigma transfer and social superiority. Study 1 (5 samples, N = 708) validates the ITG-DS scale. Higher ITG-DS scorers demonstrated greater general disgust sensitivity, disease concerns, authoritarian/conservative ideologies, and negative affect. Greater ITG-DS correlated with stronger outgroup threat perceptions and discrimination, and uniquely predicted negative outgroup attitudes beyond well-established prejudice-predictors. Intergroup disgust was experimentally manipulated in Study 2, exposing participants (n = 164) to a travel blog concerning contact with a disgust-evoking (vs. neutral) outgroup. Manipulated disgust generated negative outgroup evaluations through greater threat and anxiety. This mediation effect was moderated: Those higher (vs. lower) in ITG-DS did not experience stronger disgust, threat, or anxiety reactions, but demonstrated stronger translation of aversive reactions (especially outgroup threat) into negative attitudes. Theory development and treatment implications are considered.     

CLOSE RELATIONSHIPS AS SOURCES OF STRENGTH OR OBSTACLES FOR MOTHERS COPING WITH HIV

The current study explores the impact of HIV disease on the interpersonal relationships and social support experiences of mothers living with HIV. Analysis of interviews with 25 mothers with HIV focused on their perceptions of the impact of HIV on close relationships with significant others, including family of origin, children, friends, intimate partners, and parents. The results revealed the following major relationship challenges that mothers had to cope with after the discovery of their HIV-positive status: weighing reasons for and against disclosure of their HIV status, whether HIV disclosure brings relationship partners closer together, finding future caregivers for young children if one's health declines, and coordinating safer-sex practices with sexual partners, especially with the many males who are reluctant to use condoms. The study suggests the importance of understanding both the positive and negative aspects of social interactions in coping with HIV and the struggles that mothers have with the consequences of the HIV diagnosis for both themselves and their significant others.     

Can voicing conflict within experiential learning groups facilitate connection? building and developing effective multi-disciplinary team-working skills

In the UK, Clinical Psychologists (CPs) work in a variety of settings within the National Health Service (NHS), often within Multi-Disciplinary Teams (MDTs). Problem-Based Learning (PBL) within CP training at the University of Hertfordshire (UH) offers unique opportunities to combine scientist-practitioner and reflective-practitioner models to learn about group dynamics from the personal experience of working within an experiential learning group.

Further, given Trainees work three days per week on placement within MDTs in the NHS, the learning gained within a ‘safer’ PBL context can be utilised within these clinical settings. For two years, Trainees at UH have to work in small PBL groups with five or six members learning to work together to achieve a goal (four assessed presentations) negotiating their own personal and professional journey, as well as a group journey. Consequently, PBL offers trainees opportunities to learn (1) how individuals work within a group; (2) how personal experiences influence this process; (3) how others influence them and are influenced by them; and (4) how a group of diverse individuals conceptualise, understand and convey case vignettes to an audience. Within these groups, many Trainees learn to speak out, reflect, listen attentively, empathise, validate and accept diverse experiences. Further, when differences dominate they often learn to negotiate these, finding a way to maintain effective team working in order to complete the presentation. Focusing on the conflict that can occur within (any) group, this paper explores themes from the reflective narratives of six trainees: parallels and differences between MDTs and PBL groups, striving for and achieving authenticity; and conflict as a ‘swear’ word. We conclude that exploring the role PBL can play in training individuals to work effectively in teams may be of benefit within the training of other professional groups.     

EMS Treatment of Families in an Ambiguous Out-of-Hospital Child Death: The Role of Attribution Errors

Sometimes children die from maltreatment. However, when first responders enter a scene to save the life of a dying child, the cause of the health problem cannot be immediately determined. EMS professionals are taught to enact the medically appropriate protocols in a family-centered way. This study examines five case studies of infant deaths. When there is ambiguity as to why the death might have occurred, EMS and other emergency personnel seem to be more judgmental and this attitude affects their behavior toward family members. Family members have a more difficult time coping with the loss as a result.     

Distinctiveness helps when matching static faces and voices

Three experiments are reported which examined the capacity to match a voice with a static image of a face. When using a simultaneous same/different matching task, performance was significantly better than chance (Experiments 1 and 2). However, it did not appear to depend either on sex of speaker, sex of listener, stimulus distinctiveness, or self-reported strategies (Experiment 2). Concerns over floor effects as well as a significant response bias prompted a change of task, and when performance was examined through matching a voice to a face lineup, a more interesting pattern emerged. Again, performance was significantly better than chance, but in addition, it was demonstrably affected by the distinctiveness of the speaker’s voice. These results are considered in the context of theoretical discussions regarding face–voice integration, and in the context of more applied considerations regarding multimodal benefits in witness scenarios.     

Keeping an eye on the truth? Pupil size changes associated with recognition memory

During recognition memory tests participants' pupils dilate more when they view old items compared to novel items. We sought to replicate this "pupil old/new effect" and to determine its relationship to participants' responses. We compared changes in pupil size during recognition when participants were given standard recognition memory instructions, instructions to feign amnesia, and instructions to report all items as new. Participants' pupils dilated more to old items compared to new items under all three instruction conditions. This finding suggests that the increase in pupil size that occurs when participants encounter previously studied items is not under conscious control. Given that pupil size can be reliably and simply measured, the pupil old/new effect may have potential in clinical settings as a means for determining whether patients are feigning memory loss.     

An evaluation of emerging preference for non‐preferred foods targeted in the treatment of food selectivity

Several studies have shown that the acquisition of food consumption does not occur until after escape prevention is implemented. However, the mechanism responsible for the maintenance of food consumption may be due to participants contacting the reinforcing properties of food targeted during intervention such that the food naturally reinforces food consumption. The present study extended the literature on feeding disorders by conducting pre‐ and post‐treatment preference assessments to determine if preference for non‐preferred foods (NPFs) had developed after exposure to a treatment comparison of sequential and simultaneous food presentation; presentation methods were implemented alone and combined with escape prevention in the form of a non‐removal of the spoon (NRS) procedure. Results for three participants with food selectivity indicated that preference for NPFs developed after being exposed to those foods during either treatment sessions or generalization probes.
