What We Owe to Our Audience: The Hermeneutical Responsibility of Fiction Creators

As audiences demand better and more diverse representation in the fictions they consume, there is a question of how that demand should be placed on fiction creators. In this article, I answer this question by arguing creators of fiction have a hermeneutical responsibility to include diverse characters in their creations, and to do so without relying on harmful stereotypes. I cast this responsibility as the epistemic virtue of due diligence, offset by epistemic laziness and epistemic paralysis as the corresponding vices of absence and excess, respectively. Practicing either vice can constitute a type of hermeneutical gap described by Katharine Jenkins, in which harmful stereotypes (conceptions) become more accessible to epistemic agents than the more accurate concept. By blocking the agent's access to the accurate conception, such stereotypes create a hermeneutical gap and can contribute to hermeneutical injustices, as described by Miranda Fricker and José Medina.     

The organization of attention in typical development: A new preschool attention test battery

This article introduces a new battery of attention tests for typically developing and atypically developing children with a mental age of 3–6 years. In the light of adult and child studies supporting a model of distinct networks for specific attentional operations, tests in the current battery were selected with the aim of measuring functions of selective attention, sustained attention and attentional control (executive function). Normative data were collected from 154 typically developing children aged 3–6 years and examined using exploratory factor analysis to determine latent constructs underlying test performance. This analysis suggested increasing differentiation of attention functions over the age range, with support for the hypothesized three‐factor model only after 4½ years of age. Additional analyses supported the validity of the new attention battery with respect to (1) parent/teacher report measures of everyday attention behaviour and (2) later performance on the Test of Everyday Attention for Children (TEA‐Ch), a battery designed for children aged 6–16 years. The results show the developing differentiation of attention functions and support the ecological and predictive validity of the battery as providing early performance‐based measures of attention and an attention ‘profile’ for each individual child, which may aid characterization and remediation of neurodevelopmental disorders.     

Acute Alcohol Co‐Ingestion and Hospital‐Treated Deliberate Self‐Poisoning: Is There an Effect on Subsequent Self‐Harm?

The aim of this study was to determine the relationship between alcohol co‐ingestion in an index deliberate self‐poisoning (DSP) episode with repeated DSP and subsequent suicide. A retrospective cohort study was conducted involving 5,669 consecutive index presentations to a toxicology service following DSP between January 1, 1996, and October 31, 2010. Records were probabilistically matched to National Coronial Information System data to identify subsequent suicide. Index DSPs were categorized on co‐ingestion of alcohol, and primary outcomes analyzed were repetition of any DSP, rates of repeated DSP, time to first repeat DSP, and subsequent suicide. Co‐ingestion of alcohol occurred in 35.9% of index admissions. There was no difference between those who co‐ingested alcohol (ALC+) and those who did not co‐ingest alcohol (ALC?) in terms of proportion of repeat DSP, number of DSP events, or time to first repeat DSP event. Forty‐one (1.0%) cases were probabilistically matched to a suicide death; there was no difference in the proportion of suicide between ALC+ and ALC? at 1 or 3 years. There was no significant relationship between the co‐ingestion of alcohol in an index DSP and subsequent repeated DSP or suicide. Clinically, this highlights the importance of mental health assessment of patients that present after DSP, irrespective of alcohol co‐ingestion at the time of event.     

How does episodic memory develop in adolescence?

Key areas of the episodic memory (EM) network demonstrate changing structure and volume during adolescence. EM is multifaceted and yet studies of EM thus far have largely examined single components, used different methods and have unsurprisingly yielded inconsistent results. The Treasure Hunt task is a single paradigm that allows parallel investigation of memory content, associative structure, and the impact of different retrieval support. Combining the cognitive and neurobiological accounts, we hypothesized that some elements of EM performance may decline in late adolescence owing to considerable restructuring of the hippocampus at this time. Using the Treasure Hunt task, we examined EM performance in 80 participants aged 10–17 yr. Results demonstrated a cubic trajectory with youngest and oldest participants performing worst. This was emphasized in associative memory, which aligns well with existing literature indicating hippocampal restructuring in later adolescence. It is proposed that memory development may follow a nonlinear path as children approach adulthood, but that future work is required to confirm and extend the trends demonstrated in this study.

Episodic memory (EM) describes the ability to encode, store, and retrieve representations of previously experienced episodes and their temporal-spatial context (Tulving 1972). EM development continues well into the third decade of life (Ruggiero et al. 2016); however, its developmental trajectory after the preschool years remains controversial, with some studies suggesting linear improvements (Ofen et al. 2007) and others no improvement (Picard et al. 2012) or a nonlinear pattern (Tulving 1985; Keresztes et al. 2017). While there has been some debate as to the “defining features” of EM (Cheke and Clayton 2013, 2015) most theorists agree that it is not a unitary ability, instead reflecting the combination of a number of contributing features. Given that many of these studies used different methods for testing EM, and that different tests may emphasize different features (Cheke and Clayton 2013, 2015), it is likely that empirical differences reflect the fact that different features of memory may develop differently during later childhood and adolescence (Picard et al. 2012).The importance of understanding the developmental trajectory of EM in adolescence is highlighted in the close association between EM and other cognitive processes. EM is thought to support decision-making, particularly in the incorporation of memories into task- and goal-relevant responses (Murty et al. 2016); thus, immaturity of EM may influence the high levels of risk taking observed in adolescence. Adolescence also represents a period of vulnerability to the development of mental illness (Kessler et al. 2007). Evidence that deficits in EM have been linked to a number of mental health disorders such as depression (Goodwin 1997) and anxiety (Airaksinen et al. 2005) raises the possibility that individual differences in memory development during this period may influence this vulnerability. Finally, adolescence is a demanding time academically: During these school years, large quantities of knowledge must be acquired to be successful in exams, which have long-term impacts on individuals’ academic and professional future. It is therefore important to understand factors that may contribute to individual differences and challenges in learning and memory during this period.Memory development in adolescence has attracted considerable research attention in recent years, with the majority of work conducted on developmental trajectories of brain areas within the memory network. EM relies on a distributed network of brain areas, including the medial temporal and superior parietal lobes and the prefrontal cortex (PFC) (Simons and Spiers 2003). Each area within the network, as well as the network itself, shows protracted maturation across adolescence.
