Abusive relationships: Is a new category for traumatization needed?

The concept of a spectrum of posttraumatic disorders has been postulated by a variety of major contributors to the field of psychotraumatology. Although Posttraumatic Stress Disorder (PTSD) is one trauma-based mental health disorder, there are other posttraumatic illnesses that do not qualify for PTSD, nor are they accurately described by other diagnostic categories in the DSM-IV. The present paper proposes and delineates a new syndrome, entitled Posttraumatic Relationship Syndrome (PTRS), which is a function of the experience of trauma in the context of an emotionally intimate relationship. It differs from PTSD in four fundamental ways: (1) the nature of the Stressor criterion; (2) the response to the Stressor; (3) the inclusion of a category of relational symptoms; and (4) the way of coping with the trauma (i.e., it lacks the emotional numbing and avoidance of stimuli associated with the trauma). The latter is the most salient difference as it involves a qualitatively different experience of the “world of trauma”-a primarily conscious experience in PTRS and an often unconscious experience in PTSD.     

Nice Guys Finish Fast and Bad Guys Finish Last: Facilitatory vs. Inhibitory Interaction in Parallel Systems

Systems Factorial Technology is a powerful framework for investigating the fundamental properties of human information processing such as architecture (i.e., serial or parallel processing) and capacity (how processing efficiency is affected by increased workload). The Survivor Interaction Contrast (SIC) and the Capacity Coefficient are effective measures in determining these underlying properties, based on response-time data. Each of the different architectures, under the assumption of independent processing, predicts a specific form of the SIC along with some range of capacity. In this study, we explored SIC predictions of discrete-state (Markov process) and continuous-state (Linear Dynamic) models that allow for certain types of cross-channel interaction. The interaction can be facilitatory or inhibitory: one channel can either facilitate, or slow down processing in its counterpart. Despite the relative generality of these models, the combination of the architecture oriented plus the capacity oriented analyses provide for precise identification of the underlying system.     

The Changing Age of Individuals Seeking Presymptomatic Genetic Testing for Huntington Disease

Huntington disease (HD) is a progressive neurodegenerative disorder. Presymptomatic genetic testing allows at-risk individuals to clarify their risk status. Understanding the characteristics and motivations of individuals seeking HD presymptomatic genetic testing better equips genetic counselors and other healthcare professionals to provide comprehensive and personalized care. The aims of this study were to (1) determine whether the average age when individuals seek presymptomatic HD genetic testing has decreased over time, (2) assess motivations for seeking testing, (3) explore whether there is a relationship between age and motivations, and (4) explore genetic counselors’ perceptions of the shift in age. Data from the US HD testing centers (N?=?4) were analyzed. A small but statistically significant decrease in age of individuals seeking presymptomatic testing was observed (p?=?0.045). HD community members (N?=?77) were surveyed regarding presymptomatic testing motivations. Younger individuals were more likely than older individuals to cite “To learn whether or not you would develop HD” and “To make choices about further education or a career” compared to older individuals (p?<?0.05). Conversely, older individuals more frequently cited “To give children a better idea of their risk” (p?<?0.002). Sixteen percent of genetic counselors surveyed (6/37) perceived a change in age of testing. All of these respondents had provided HD testing for ten or more years and anecdotally believed the age at testing has decreased over time. Study results help providers personalize counseling based on patient’s age and serve as a starting point for more research into the relationship between age at testing and motivations for testing.     

People with Chronic Pain and Caregivers: Experiencing Loneliness and Coping with It

The present study examined the experience of loneliness and the ways of coping with its pain as utilized by people with chronic pain and caregivers. Specifically, a large sample (N = 827) recruited in two major pain clinics in Israel, completed the Loneliness and the Coping with loneliness questionnaires. Results indicated that patients had higher scores than caregivers in Emotional distress, Social inadequacy and alienation, Interpersonal isolation, and in Self-alienation. There was no significant difference between the groups in the Growth and discovery subscale. Comparing patients and caregivers on coping with loneliness, patients had higher scores than caregivers in Reflection and acceptance, and in Self-development and understanding. No significant difference between the groups was found in Social support, Distancing and denial, Religion and faith, and on Increased activity.     

A reach-to-touch investigation on the nature of reading in the Stroop task

In a Stroop task, participants can be presented with a color name printed in color and need to classify the print color while ignoring the word. The Stroop effect is typically calculated as the difference in mean response time (RT) between congruent (e.g., the word RED printed in red) and incongruent (GREEN in red) trials. Delta plots compare not just mean performance, but the entire RT distributions of congruent and incongruent conditions. However, both mean RT and delta plots have some limitations. Arm-reaching trajectories allow a more continuous measure for assessing the time course of the Stroop effect. We compared arm movements to congruent and incongruent stimuli in a standard Stroop task and a control task that encourages processing of each and every word. The Stroop effect emerged over time in the control task, but not in the standard Stroop, suggesting words may be processed differently in the two tasks.     

Self-perception of the antecedents of loneliness among new mothers and pregnant women

This study examined the perceived causes of loneliness of pregnant women and mothers during the first year after childbirth experience. These were compared with the causes of loneliness of women in the general population. 91 pregnant women, 97 women during the first year following childbirth, and 208 women from the general population (M age = 30.4, SD = 10.4) answered a 29-item Loneliness Antecedents Questionnaire. In the questionnaire were 5 dimensions of sources of loneliness, namely, Personal Inadequacies, Developmental Deficits, Unfulfilling Intimate Relationships, Relocation/Significant Separation, and Social Marginality. Sources of loneliness were significantly different amongst the three groups. The differences were confined to the Personal Inadequacies, and the Relocation/Significant Separation subscales. In both, women from the general population had the highest mean subscale scores.     

Religiosity and coping with loneliness

Loneliness is a universal experience which transcends age, sex, geography, and culture. Religion, and often one's religiosity, are known to affect one's approach to life, behaviour, and social involvement. The present, preliminary study aimed to explore whether coping with loneliness is influenced by one's religious observance. The present study focused on Israeli Jews. 250 participants identified themselves as Secular, Conservative, or Orthodox, by answering a 34-item yes/no questionnaire on loneliness. The three groups statistically significantly differed in their manner of coping with loneliness only on the Religion and Faith subscale, as hypothesized. Similar studies with people of other religious denominations could further highlight that issue.     

Loneliness and the Effects of Life Changes

In this study, factor analysis was used to examine whether men and women experience loneliness differently and how marital status affects the experience of loneliness (especially if the marriage is terminated). The experiences of chronic and situational or event-related loneliness are also compared. Finally, the study is also an investigation of the social stigma that causes people to refuse to admit their loneliness. As a result of this stigma, when questioned for research purposes, individuals usually report a recall of past loneliness rather than a current or ongoing experience. In the present study, the difference between loneliness recalled and loneliness experienced at the time of questioning is investigated.     

The resurrection of Tweedledum and Tweedledee: Bimodality cannot distinguish serial and parallel processes

Simultaneously presented signals may be processed in serial or in parallel. One potentially valuable indicator of a system’s characteristics may be the appearance of multimodality in the response time (RT) distributions. It is known that standard serial models can predict multimodal RT distributions, but it is unknown whether multimodality is diagnostic of serial systems, or whether alternative architectures, such as parallel ones, can also make such predictions. We demonstrate via simulations that a multimodal RT distribution is not sufficient by itself to rule out parallel self-terminating processing, even with limited trial numbers. These predictions are discussed within the context of recent data indicating the existence of multimodal distributions in visual search.
