The role of rehearsals in self-generated prospective memory tasks

In order to inquire into the nature of retrieval in prospective memory in a naturalistic context, we investigated the number and circumstances of rehearsals of different kinds of intentions to be pursued during a single time period. Thirty-six students were given four minutes to generate a list of tasks they were planning to perform over the course of 10 days. During this retention interval, they were provided with pocket-size diaries in which they recorded the details of each occasion they thought about the tasks previously listed. As to the nature of any triggers or cues that prompted rehearsal, the participants were asked to choose one of three alternatives: (1) association with an internal or an external cue that accidently appeared in the surroundings (accidental rehearsals), (2) deliberate thinking, e.g. while planning (self-initiated rehearsals), (3) recollection that spontaneously popped into one's mind for no apparent reason (no-trigger rehearsals). The results showed that thoughts about intended actions appeared more often after accidental cues than for no apparent reason. However, the relative contribution of self-initiated triggers to the rehearsal process was substantial: Most importantly, it was the self-initiated rehearsal that differentiated between executed and unexecuted actions. In addition, the most activated intention resulted in a higher frequency of no-trigger and self-initiated rehearsals than the remaining intentions. Finally, perceived intention importance was positively related to both the number of rehearsals and the likelihood of successful task completion. The results are discussed with regard to which factors may be crucial for the successful performance of participants' own self-generated intentions in a natural setting. The role of deliberate rehearsal in specifying the details of the intended action and its designated retrieval context is highlighted.     

Representation and Reasoning about Evolutions of the World in the Context of Reasoning about Actions

The first step in reasoning about actions and change involves reasoning about how the world would evolve if a certain action is executed in a certain state. Most research on this assumes the evolution to be only a single step and focus on formulating the transition function that defines changes between states due to actions. In this paper we consider cases where the evolution is more than just a single change between one state and another. This is manifested when the execution of an action may trigger execution of other actions, or when multiple agents act on the environment following certain strategies.     

The discourse of being ‘triggered’: Uses and meanings among counselling students

Despite the initial understanding of the word ‘triggered’ as relating to the clinical phenomenon of post-traumatic stress disorder (PTSD), this language has become a common part of the vernacular today, used by many people to apply to a wide variety of experiences and events. Counselling students are particularly sensitised to trauma, as well as identity politics, and are familiar with trigger warnings at college. They themselves have experienced trauma at high rates. Therefore, we were interested to understand how they might be using the word and interpreting the experience of being ‘triggered’, whether different sources of being triggered are related to emotional reactions, and whether a discourse analysis might indicate how and why the term has become useful and for what other experiences it might be serving as a stand-in. In this mixed-methods study, 79 counselling students from around the country shared their definitions and experiences of being ‘triggered’. Participants completed surveys and wrote narratives, which, via thematic qualitative analysis, were coded into five themes. The quantitative analysis focused on the relationship of feelings to themes and the relationship between anger suppression and coping with each theme. Discourse analysis explored how individuals wrote about responsibility and anger. It was discovered that those who wrote about being triggered from a past sexual assault did not discuss anger, nor the responsibility of others to protect them (as those who wrote about microaggressions did), but positioned themselves as overreactors. Results are discussed with regard to training and practice.     

Nostalgia reconsidered

Nostalgia is standardly assumed to be directed towards the past, to involve some salient feeling of the irretrievability of the past, and to be directed towards the memory of an event. In this paper I argue that none of these standard assumptions hold. I use a time-traveller example to demonstrate that nostalgia is not essentially past-directed. Once nostalgia is prised from the objective past, we can examine the other purported conditions, making space for the conclusion that the felt irretrievability of the past is not the necessary feature of nostalgia that we assumed it to be. I then argue that the notion that nostalgia is directed towards the memory of an event is misguided. Finally, I distinguish two routes to nostalgia and, with this distinction in place, argue that nostalgia is neither essentially time nor place directed. Nostalgia is simply change-directed.     

Stress as a trigger for headaches: Relationship between exposure and sensitivity

Abstract

This study investigated the relationship between length of exposure to a stressor and capacity of the stressor to elicit head pain. Some 127 participants, 93 of whom suffered from regular headaches, were randomly assigned to five experimental conditions, defined by length of exposure to a stressor. Participants attended a single laboratory session divided into three phases: pre-intervention test, intervention and post-intervention test. The main finding was a significant cubic trend between length of exposure to the stressor and ratings of head pain. This trend indicated that very short exposure to the stressor increased sensitivity, whilst longer exposure decreased sensitivity, but even longer exposure increased sensitivity. These results build on earlier studies that suggest the traditional clinical advice to headache sufferers, that the best way to prevent headaches is to avoid the triggers, runs the risk of establishing an insidious sensitization process, thereby increasing headache frequency.     

Personality and individual differences in responses to aggression triggering events among prisoners and non-prisoners

This paper examines the relationships between individual differences in situational triggers of aggressive behaviors (STAR) and the FFM personality traits. The investigation, conducted among Polish male and female offenders and students, revealed different relationships across samples. Among students, higher sensitivity to frustration and provocation was related to higher Neuroticism and lower Agreeableness and sensitivity to provoking situations to lower Openness to Experience. Among prisoners, however, lower Agreeableness was negatively linked to being more sensitive to provocation. Furthermore, the study found sex differences in STAR scales in the student sample but not the prisoners’ sample.     

Nanoregulation—Filtering Out the Small Stuff

Whilst there are not yet laws specifically relating to nanotechnology and its products in any country, the technology and its products are not unregulated. Regulatory frameworks created for conventional technologies and products will be expected to apply to nanotechnology and its products. For example, new medicines are regulated in Australia by the Therapeutic Goods Administration. If a new medicine incorporates nanotechnology, then it should still be regulated as a medicine. However, whether the expectation that pre-existing regulatory frameworks will apply is correct and, if so, whether the application of such frameworks is adequate are important issues to be answered. This paper considers these questions, drawing on lessons learnt from significant regulatory reviews undertaken in the United Kingdom, United States and Australia.
