A Trauma-Informed Call to Action: Culturally Informed,Multi-Disciplinary Theoretical,and Applied Approaches to Prevention and Healing,Part II

The prevalence of trauma and its negative impact on humankind have created a burgeoning awareness of the need for systems that are trauma-informed across the lifespan. A collaborative project with the National Partnership to End Interpersonal Violence (NPEIV) sought out research as a call-to-action to mitigate the impact of trauma. The following is Part II of an introduction to a special double-issue focused on theoretical and applied approaches to using trauma-informed care in multi-disciplinary, mental and physical health, criminal justice, school-based, and community settings. Consideration is given to essential issues such as resilience, self-care, and intersectional cultural awareness. Introspective exploration of biases was encouraged to address barriers to implementing trauma-informed care.     

Spatial and temporal separation fails to counteract the effects of low prevalence in visual search

Recent research has shown that, in visual search, participants can miss 30–40% of targets when they only appear rarely (i.e., on 1–2% of trials). Low target prevalence alters the behaviour of the searcher. It can lead participants to quit their search prematurely (Wolfe, Horowitz, & Kenner, 2005), to shift their decision criteria (Wolfe et al., 2007), and/or to make motor or response errors (Fleck & Mitroff, 2007). In this paper we examine whether the low prevalence (LP) effect can be ameliorated if we split the search set in two, spreading the task out over space and/or time. Observers searched for the letter “T” among “L”s. In Experiment 1, the left or right half of the display was presented to the participants before the second half. In Experiment 2, items were spatially intermixed but half of the items were presented first, followed by the second half. Experiment 3 followed the methods of Experiment 2 but allowed observers to correct perceived errors. All three experiments produced robust LP effects with higher errors at 2% prevalence than at 50% prevalence. Dividing up the display had no beneficial effect on errors. The opportunity to correct errors reduced but did not eliminate the LP effect. Low prevalence continues to elevate errors even when observers are forced to slow down and permitted to correct errors.     

Guidance of attention by information held in working memory

Information held in working memory (WM) can guide attention during visual search. The authors of recent studies have interpreted the effect of holding verbal labels in WM as guidance of visual attention by semantic information. In a series of experiments, we tested how attention is influenced by visual features versus category-level information about complex objects held in WM. Participants either memorized an object’s image or its category. While holding this information in memory, they searched for a target in a four-object search display. On exact-match trials, the memorized item reappeared as a distractor in the search display. On category-match trials, another exemplar of the memorized item appeared as a distractor. On neutral trials, none of the distractors were related to the memorized object. We found attentional guidance in visual search on both exact-match and category-match trials in Experiment 1, in which the exemplars were visually similar. When we controlled for visual similarity among the exemplars by using four possible exemplars (Exp. 2) or by using two exemplars rated as being visually dissimilar (Exp. 3), we found attentional guidance only on exact-match trials when participants memorized the object’s image. The same pattern of results held when the target was invariant (Exps. 2–3) and when the target was defined semantically and varied in visual features (Exp. 4). The findings of these experiments suggest that attentional guidance by WM requires active visual information.     

Creating All in the Family: A Case Study in Creative Thinking

Research examining the development of creative works suggests that creative products often build on previous works and that, in such cases, the new work can be seen as an extension and synthesis of works known to the creator at that time (Weisberg, 2003a). In recent years, several investigators have applied quantitative methods to the analysis of the development of creative works (e.g., Martindale, 1990; Simonton, 1998; Weisberg, 2003b). The present study extended this quantitative orientation to the analysis of the development of the innovative 1970s television show All in the Family (AITF). The family structure, character portrayals, topical emphases, and goals of AITF were compared with those of its purported "parent," the British situation comedy Till Death Us Do Part (TDUDP), as well as with those of 4 "control" U.S. situation comedies. Statistical analyses demonstrated significant relationships between AITF and TDUDP, while showing significant differences between AITF and TDUDP and the other American shows. Many of the innovations in AITF can be seen as extensions of ideas present in TDUDP. The present study provides further evidence for the feasibility and usefulness of applying quantitative methods to the analysis of the development of creative products. On a substantive level, it appears that AITF represents another in a long line of creative products that built on and extended what was already available to create something new.     

Suicide Ideation and Attempts among Inhalant Users: Results from the National Epidemiologic Survey on Alcohol and Related Conditions

Few studies have examined associations of inhalant use and inhalant use disorders (IUDs) to suicide ideation and attempts. We investigated these relationships in the largest comorbidity survey conducted in the United States. Suicidal ideation was significantly more prevalent among inhalant users than nonusers and severity of inhalant use problems was positively related to suicidal ideation. Among persons with IUDs, 67.4% had thought about committing suicide and 20.2% had attempted suicide. Multivariate logistic regression analyses indicated that respondents with IUDs reported significantly higher levels of suicide ideation than inhalant nonusers. Inhalant use is associated with significantly increased risk for suicide ideation, especially among women and persons with DSM‐IV IUDs.     

Association Between Suicidal Ideation and Exposure to Suicide in Social Relationships Among Family,Friend, and Acquaintance Survivors in South Korea

Exposure to suicide in social relationships may be associated with suicidal ideation among survivors. In South Korea, which is known for having the highest suicide rate among OECD countries, exposure to suicide in social relationships can have serious consequences as social relationships are greatly emphasized in the society. The purpose of this study was to examine the association between survivors' suicidal ideation and their exposure to suicide in close relationships. Data collected through a telephone survey of a total of 1,000 men and women selected from across the nation using a stratified sampling method were analyzed. The results show that individuals who lost a family member, friend, or acquaintance in their lifetime are 4.5 times, 3.7 times, 2.2 times, respectively, more likely to have suicidal ideation in the past year compared to those without such experience. These findings suggest that special intervention for suicide survivors should be considered for those who experience suicide in close relationships.
