记忆源检测的加工分离

同一个记忆源检测任务是否可以依赖两种不同的加工——无意识启发式加工和有意识系统式加工,是源检测加工机制研究探索的一个重要问题。本研究拟借助加工分离程序来分离同一个源检测任务中的启发式和系统式加工,并进一步考察了启发式和系统式加工受刺激呈现时间的影响。结果发现:位置源检测任务依赖于启发式和系统式两种加工,且随着刺激呈现时间的增长,系统式加工的贡献显著地提高,启发式加工的贡献却无显著提升。这一结果既验证了记忆源检测的双加工机制,也暗示了两种加工在加工深度上的差异。     

Response to Ranganathan

This essay responds to Bharat Ranganathan's “Comment” on my essay, “The Concept of Dignity in the Universal Declaration of Human Rights” (2011). Addressing key criticisms in this “Comment,” I make the following points. First, neither the idea of inherent dignity being “imparted” to humans, nor the Universal Declaration's implication—through its use of terms such as “inherent” and “inalienable”—that humans participate in transcendent reality, necessarily presuppose a Christian metaphysics. Second, a concept such as “inherent dignity” must be affirmed to be intrinsically heuristic unless we are to assume that its meaning can be completely known within the conditions of existence; but this affirmation does not render such concepts “indeterminate of sense.” Finally, Ranganathan's distinction between“weak” and “strong” senses of transcendence is untenable. If human truths beyond all contingencies are knowable (“weak” transcendence), then there must be a real dimension of meaning that transcends all contingencies (“strong” transcendence).     

Does integral affect influence intentions to use artificial intelligence for skin cancer screening? A test of the affect heuristic

Objective: This study investigated how affect influences people’s processing of messages about risks and benefits of using autonomous artificial intelligence (AI) technology to screen for skin cancer. We examined integral affect (emotion derived during decision making) separately from incidental affect (extraneous mood states).

Design: Using the affect heuristic framework, we randomly assigned 273 participants to conditions featuring risk (high, low, uncertain) or benefit (high, low, uncertain) messages about AI. Following ‘affect-as-spotlight’, we also explored whether people’s integral affect towards skin cancer moderated the relationship between risk/benefit messages and AI screening intentions.

Outcomes: Perceived risk, perceived benefit, positive and negative affect toward AI, intention to use AI screening.

Results: After controlling for incidental affect and risk perceptions, we found that compared to low risk messages, uncertain risk messages increased participants’ negative affect toward AI, decreased positive affect toward AI, increased AI risk evaluations and reduced AI benefit evaluations. Perceptual variables significantly mediated participants’ intentions to use AI for risk messages but not benefit messages. No moderation effects were found.

Conclusions: Results suggest extending the affect heuristic framework to include uncertain risk conditions. Integral AI affect influenced people’s interpretation of messages, which then impacted likelihood to use AI technology for health.     

Less is more: The availability heuristic in early childhood

This study examined whether young children are influenced by the subjective experience associated with an easy or difficult recall when making memory decisions. Seventy‐one children, aged 4, 6, and 8 years, were asked to generate either a small (easy condition) or large (hard condition) number of first names. Statistical analyses revealed that participants in the hard condition were more likely to infer that they did not know many names than participants in the easy condition, contrary to what would be expected if children based their memory judgement on the objective number of recalled items. Overall, our results support the hypothesis that children as young as 4 years old rely on the subjective experience of ease to regulate their decision‐making processes. Theoretical implications of these findings are discussed.     

Epistemic Judgments are Insensitive to Probabilities

Multiple epistemological programs make use of intuitive judgments pertaining to an individual’s ability to gain knowledge from exclusively probabilistic/statistical information. This paper argues that these judgments likely form without deference to such information, instead being a function of the degree to which having knowledge is representative of an agent. Thus, these judgments fit the pattern of formation via a representativeness heuristic, like that famously described by Kahneman and Tversky to explain similar probabilistic judgments. Given this broad insensitivity to probabilistic/statistical information, it directly follows that these epistemic judgments are insensitive to a given agent’s epistemic status. From this, the paper concludes that, breaking with common epistemological practice, we cannot assume that such judgments are reliable.     

A trainee psychotherapist’s heuristic exploration of losing a mother to suicide

ABSTRACT

Suicide bereavement is a newly developing field of research in the UK, yet over 6,600 people take their own lives here every year. This heuristic inquiry aims to explore the lived experiences of trainee psychotherapists bereaved by maternal suicide. It examines the lived experiences of the researcher and two participants, with data collected through interviews, dreams and journalling. The findings revealed five themes: 1) It’s not just about the suicide, 2) The pain continues – attachment, abandonment and fear, 3) Left with all the unprocessed feelings – “the shit”, 4) Trigger after trigger – complicated experiences of psychotherapy training, 5) A catastrophic loss that no one “gets”. Implications for the counselling and psychotherapy profession are discussed.
