    One Eye on the Prize: The Impact of monocular vision on aiming responses

    Full text link
    The ability to move one's hand quickly and accurately towards a target is an essential skill that underpins many activities of daily living, such as writing or threading a needle. In-lab research has previously demonstrated that the time taken to complete an aiming task is proportional to task difficulty; however, the strength of this relationship appears to reduce as the quality of visual input becomes degraded (Wu et al, 2010). There is also evidence that when compared to full vision, monocular vision leads to a general increase in movement time during aiming tasks (Sheppard et al, 2021). Despite these valuable findings, logistical challenges (e.g. recruitment from hard-to-reach populations) make in-lab testing difficult or even impossible. These potential challenges could be overcome by introducing online tests if they are sufficiently sensitive to capture visual deficits accurately. The present study aimed to test (i) whether monocular vision was associated with increased response time and (ii) the feasibility of using simple, online tasks to probe the relationship between visual and motor function. Using a computer mouse or touchpad to move to targets as quickly as possible, 65 participants (aged 18–77) completed (i) a visual search task (moving to a 34 target embedded amongst a grid of distractors) and (ii) a basic visual-motor aiming task (moving to individual targets of varying size/distance). Participants completed both tasks online, either with full vision or monocular vision. Visual search time and aiming task response time increased significantly under monocular vision (≈1.8 s and ≈40 ms, respectively). These results suggest that a simple, online aiming task can be suitable for testing the effects of a visual deficit on motor function

    Folk Conceptions of Free Will: A Systematic Review and Narrative Synthesis of Psychological Research

    No full text
    The existence of free will has been a subject of fierce academic debate for millennia, still the meaning of the term “free will” remains nebulous. In the past two decades, psychologists have made considerable progress in defining lay concepts of free will. We present the first systematic review of primary psychological evidence on how ordinary folk conceptualise free will, encompassing folk concepts, beliefs, intuitions, and attitudes about free will. A total of 1,384 records were identified following a pre-registered protocol. After abstract and full-text screening, 18 articles were eligible for inclusion, comprised of 36 studies and 10,176 participants from regions including the United States, Singapore, Hong Kong, India, Turkey, and Germany. A narrative synthesis of results showed that for ordinary folk, especially the more educated population from the United States, free will is a dynamic construct centred on the ability to choose following one’s goals and desires, whilst being uncoerced and reasonably free from constraints. Results suggesting metaphysical considerations regarding consciousness, dualism, and determinism were inconclusive. Our findings provided preliminary support for a psychological model of folk conception of free will, and elucidated potential pathways mediating the effects of consciousness and dualism on free will attributions. Further research is needed to explicate the distinction between having free will and having the ability to exercise free will, as well as the cross-cultural validity of findings on folk conceptions of free will

    Psychology’s Theory Crisis, and why formal modelling cannot solve it

    No full text
    In light of psychology’s ‘theory crisis’, multiple authors have argued that adopting formalization and/or formal modelling would constitute a useful or even necessary step towards stronger psychological theory. In this article, I instead argue that formal modelling cannot solve the core problem the psychological ‘theory crisis’ refers to, which are the currently high degrees of contrastive and holistic underdetermination of our theories by our data. I do so by first introducing underdetermination as an explanatory framework for determining the evidential import of research findings for theories, and showing how both broader theoretical considerations and informal assumptions are key to this process. Then, I derive the aforementioned core problem from the current ‘theory crisis’ literature and tentatively explore its possible solutions. Lastly, I show that formal modelling is neither a necessary nor sufficient solution for either contrastive or holistic underdetermination, and that its uncritical adoption might instead worsen the crisis
