The relationship between indecisiveness and eye movement patterns in a decision making informational search task

Indecisiveness is a trait‐related general tendency to experience decision difficulties across a variety of situations, leading to decision delay, worry, and regret. Indecisiveness is proposed (Rassin, 2007) to be associated with an increase in desire for information acquisition and reliance on compensatory strategies—as evidenced by alternative‐based information search—during decision making. However existing studies provide conflicting findings. We conducted an information board study of indecisiveness, using eye tracking methodology, to test the hypotheses that the relationship between indecisiveness and choice strategy depends on being in the early stage of the decision making process, and that it depends on being in the presence of an opportunity to delay choice. We found strong evidence for the first hypothesis in that indecisive individuals changed shift behavior from the first to the second half of the task, consistent with a move from greater to lesser compensatory processing, while the shift behavior of decisive individuals suggested lesser compensatory processing over the whole task. Indecisiveness was also related to time spent viewing attributes of the selected course, and to time spent looking away from decision information. These findings resolve past discrepancies, suggest an interesting account of how the decision process unfolds for indecisive versus decisive individuals, and contribute to a better understanding of this tendency.

Local communities responding to ecological challenges—A psycho‐social approach to the Natura 2000 Network

The institutionalization of biodiversity conservation through legal instruments has led to mixed reactions at both the individual and community levels, with conflict and resistance co‐existing with support. The overall purpose of this paper is to describe how rural communities living in areas included in the Natura 2000 Network of protected sites, where local practices of land use are regulated by new legal directives, receive biodiversity conservation goals. Previous studies suggest that this reception is strongly shaped by place identification, but their contradictory results demand further clarification. This study examines the role of psycho‐social variables identified by previous studies as potentially relevant moderators of identification: (a) Vested interest in natural resources, (b) evaluation of the designation process of protected areas and (c) institutional trust. It further extends previous research by analysing the support given to contextually relevant ecological practices. Results reveal a positive link between place identification and attitudes in the high vested interest condition and show that support for conservation practices is better predicted in the high vested interest and low trust conditions. The discussion focuses on the relevance of analysing contextually relevant psycho‐social moderators when attempting to understand how local communities' relation with biodiversity conservation is affected by legislative innovation.

Eye movements reduce vividness and emotionality of “flashforwards”

Earlier studies have shown that eye movements during retrieval of disturbing images about past events reduce their vividness and emotionality, which may be due to both tasks competing for working memory resources. This study examined whether eye movements reduce vividness and emotionality of visual distressing images about feared future events: “flashforwards”. A non-clinical sample was asked to select two images of feared future events, which were self-rated for vividness and emotionality. These images were retrieved while making eye movements or without a concurrent secondary task, and then vividness and emotionality were rated again. Relative to the no-dual task condition, eye movements while thinking of future-oriented images resulted in decreased ratings of image vividness and emotional intensity. Apparently, eye movements reduce vividness and emotionality of visual images about past and future feared events. This is in line with a working memory account of the beneficial effects of eye movements, which predicts that any task that taxes working memory during retrieval of disturbing mental images will be beneficial.     

Creating analysts, creating analytic patients

This paper applies a contemporary, 'two-track'- transformational as well as archaeological - perspective on psychoanalytic process to clinical issues in the creation of analytic patients: case finding, recommending analysis, and recommending and negotiating the intensification of frequency of sessions in analytic psychotherapy. Central importance is assigned to the role of the mind and analytic identity of the analyst, including the analyst's capacity to maintain an internal analytic frame and analyzing attitude from the very first contact with the patient and throughout the treatment, the analyst's confidence in and conviction about the usefulness of analysis for a given analytic dyad and the role of the analyst's theory, which must be broad and consistent enough to allow the analyst to feel that he or she is operating analytically when addressing non-neurotic (unrepresented and weakly represented mental states) as well as neurotic structures.     

From Poisson shot noise to the integrated Ornstein-Uhlenbeck process: Neurally principled models of information accumulation in decision-making and response time

In the diffusion model of decision-making, evidence is accumulated by a Wiener diffusion process. A neurally motivated account of diffusive evidence accumulation is given, in which diffusive accumulation arises from an interaction between neural integration processes operating on short and long time scales. The short time scale process is modeled as a Poisson shot noise process with exponential decay. Stimulus information is coded by excitatory-inhibitory shot noise pairs. The long time scale process is modeled as algebraic integration, possibly implemented as a first-order autoregressive process realized by recurrent connections within a population of neurons. At high intensities, an excitatory-inhibitory shot noise pair converges weakly to an Ornstein-Uhlenbeck (OU) velocity process. The integrated OU process, or OU displacement process, obtained by integrating the velocity process over time, is indistinguishable at long times from the Wiener process. Diffusive information accumulation may therefore be characterized as an integrated OU process whose properties mimic those of the Wiener process.     

An exploration of the mechanisms of change following an integrated group intervention for stuttering,as perceived by school-aged children who stutter (CWS)

PurposeTo explore the process of change and role of resilience following an integrated group intervention for children who stutter (CWS).MethodUsing an exploratory multiple case study design, this research sought to identify the most significant changes perceived by seven participants following therapy, the mechanisms of change, and the role of resilience in the process of change. Quantitative measurements of resilience were combined with qualitative analysis of semi-structured interviews.ResultsThematic analysis of qualitative data showed that cognitive and emotional change was a key driver for therapeutic change, enabled by the shared experience of the group and a positive therapeutic environment. These changes were generalised into clients’ real-world experiences, facilitated by their support network. Quantitative data demonstrated a statistically reliable positive change in overall Resiliency scores for four participants and reduced impact of stuttering scores on OASES-S for all participants, maintained at 12 month follow-up.ConclusionsThis study demonstrates the importance of adopting an integrated approach in therapy for CWS, which incorporates Cognitive Behavioural Therapy (CBT) as a key component, to facilitate change and build resilience. These results are unique to this cohort of CWS and further investigation into the use of CBT and the process of change may be warranted.Educational ObjectivesThe reader will be able to (1) describe the integrated intervention used in this study (2) define the most significant change following therapy for the participants involved (3) summarise the key factors that facilitated change during the therapy process (as perceived by the participants).
