Neuropsychological Performance in Gulf War Era Veterans: Motivational Factors and Effort

Assuming that the underlying etiology of unexplained health-related symptoms in returning Gulf War (GW) veterans is multifactorial, the possible role of feigning or exaggeration of symptoms is worth consideration as a contributing factor. The present study assessed the relationship between motivation to perform well during neuropsychological assessment and objective neuropsychological test performance. Motivation was measured as the score on a visual memory task (Test of Memory Malingering, TOMM) of low difficulty. Participants included 77 veterans from the cohorts of GW- (n = 58) and Germany-deployed (n = 19) GW-era veterans described in two other papers in this issue who were administered the TOMM. Most veterans earned perfect or near-perfect scores on the TOMM (48–50/50). Scores 47 were associated with lower scores on neuropsychological tasks assessing attention, executive functions, and memory. Variability in test performance within and between tasks measuring similar functions was also found in participants with lower TOMM scores.     

Testing two theories of conceptual combination: alignment versus diagnosticity in the comprehension and production of combined concepts

People often interpret novel noun-noun combinations by transferring a property from one constituent concept of the combination to the other. Two theories make different predictions about these "property" interpretations. Dual-process theory predicts that properties transferred will be alignable differences of the concepts being combined. Constraint theory predicts that properties transferred will be diagnostic properties of the concepts in which they originate. An experimental study tested these contrasting predictions in interpretation comprehension and interpretation production tasks. The results showed that participants reliably preferred diagnostic property interpretations, whether alignable or nonalignable, in both tasks. There was no reliable preference for alignable interpretations in either task. This confirms constraint theory's predictions about property interpretations and goes against the predictions of dual-process theory.     

Narratives of Treatment Outcome

This article is based on the findings of an interview study that explored the discourses clinicians draw on in their narratives in relation to self-injury. More specifically, the study focused on the clinicians’ discourses of responsibility for treatment outcome, and how they construct concepts of success, failure, and partial failure. Eight mental health clinicians from various disciplines who employed a range of treatment modalities were selected using purposive sampling. An in-depth conversational-style interviewing approach was used. The findings of the study highlight the complexities and difficulties the clinicians encountered with regard to the evaluation of their clinical practice with self-injuring patients. It appears that clinicians have little or no systematic way of thinking or conceptualizing “progress” with regard to self-injury. In relation to who is responsible for treatment outcome, the clinicians occupied various discursive positions. These findings have implications for the education and training of clinicians in developing systematic indicators of progress with respect to self-injury and in creating spaces in which they can speak about and reflect on their clinical effectiveness and failures.     

Constructing the Conditions of and Environments for Interdisciplinary Research on Perception and Action

This paper suggests ways in which art processes may contribute to the interdisciplinary study of perception and action and the relationships between body, person, and environment. Artists-turned-architects Arakawa and Gins serve as the most advanced example of an interdisciplinary research project in terms of coordinating material processes with contemporary findings, methods, and orientations from across the arts, humanities, and hard and soft sciences. In the first section of the paper, I discuss Arakawa and Gins's Reversible Destiny Lofts at Mitaka as an example of their procedural approach to long-term sustainable experimental environments. In the second section, the tactics through which Arakawa and Gins have repositioned art for the nonart purposes and common research goals are posited. Finally, I briefly outline the disciplinary positions and research values needed in order to move toward a more inclusive and interdisciplinary research practice.     

To think or not to think,that is the question: Individual differences in suppression and rebound effects in autobiographical memory

Two studies explored the effects of forget instructions on autobiographical memory at immediate test and following delays of either 12–13 months, or 3–4 months. Using the Autobiographical Think/No-Think procedure (cf., Noreen & MacLeod, 2013), 24 never-depressed participants (Study 1) first generated 12 positive and 12 negative autobiographical memories and associated cues. Participants were then asked to recall the memory associated with some of the cues (i.e., ‘think’ condition), or to avoid saying or thinking about the memory associated with other cues (i.e., ‘no-think’ condition). Participants were then asked to recall the memories associated with all the cues at immediate test and following a delay of 12–13 months. Participants were found to be successful at forgetting both positive and negative autobiographical memories following ‘no-think’ instructions at immediate test but this forgetting effect did not persist following a 12–13 month delay. This pattern of remembering and forgetting was replicated in a second study (using 27 never-depressed participants) following a 3–4 month delay. Participants who had been less successful at forgetting ‘no-think’ memories at immediate test, were more likely to show rebound effects for those memories following a delay compared to memories which received neither ‘think’ nor ‘no-think’ instructions. Individual differences in inhibitory control and the efficacy of potential therapeutic interventions of ‘no-think’ instructions are considered.     

Efficient Creativity: Constraint‐Guided Conceptual Combination

This paper describes a theory that explains both the creativity and the efficiency of people's conceptual combination. In the constraint theory, conceptual combination is controlled by three constraints of diagnosticity, plausibility, and informativeness. The constraints derive from the pragmatics of communication as applied to compound phrases. The creativity of combination arises because the constraints can be satisfied in many different ways. The constraint theory yields an algorithmic model of the efficiency of combination. The C³ model admits the full creativity of combination and yet efficiently settles on the best interpretation for a given phrase. The constraint theory explains many empirical regularities in conceptual combination, and makes various empirically verified predictions. In computer simulations of compound phrase interpretation, the C³ model has produced results in general agreement with people's responses to the same phrases.     

Bullying: a source of chronic post traumatic stress?

This study surveyed 165 care professionals on their experience of workplace bullying. The results showed that in a 2-year period 40% had been bullied and 68% had observed bullying taking place. Of the 67 care professionals that had been bullied 44% were experiencing high levels of PTSD symptoms based on the general factor of the IES-E. However, when these results were examined further it was found that the symptoms clustered rather differently to those of victims of other forms of trauma. In victims of bullying, the symptoms of arousal and re-experience formed a single cluster of symptoms with avoidance remaining as a separate cluster. These results are challenging in both the classification of Post Traumatic Stress Disorder and for the treatment of victims of bullying.     

Empathetic Computers: The Problem of Confusing Persons and Things

As computers become both more intelligent and ubiquitous we increasingly rely on them for forms of companionship. We are relational beings, instinctively drawn to those who relate back to us, an instinct that is rooted in our creation in the image of a triune, and thus relational, God. Relationships with computers, which necessarily displace relationships with other humans, have so far been shown to be dissatisfying. This dissatisfaction arises because a computer cannot be truly empathetic. It cannot feel emotion due to its lack of a body; it can only simulate emotion. This makes relationship with a computer similar to relationship with a sociopath and can isolate us from both others and our true selves.
