Temporal encoding strategies result in boosts to final free recall performance comparable to spatial ones

The method of loci is a highly effective mnemonic that recruits existing salient memory for spatial locations and uses the information as a scaffold for remembering a list of items (Yates, 1966). One possible account for the effectiveness of the spatial method of loci comes from the perspective that it utilizes evolutionarily preserved mechanisms for spatial navigation within the hippocampus (Maguire et al. in Proceedings of the National Academy of Sciences, 97(8), 4398–4403, 2000; O’Keefe & Nadel, 1978; Rodriguez et al. in Brain Research Bulletin, 57(3), 499–503, 2002). Recently, though, neurons representing temporal information have also been described within the hippocampus (Eichenbaum in Nature Reviews Neuroscience, 15(11), 732–744, 2014; Itskov, Curto, Pastalkova, & Buzsáki in The Journal of Neuroscience, 31(8), 2828–2834, 2011; MacDonald, Lepage, Eden, & Eichenbaum in Neuron, 71(4), 737–749, 2011; Mankin et al. in Proceedings of the National Academy of Sciences, 109(47), 19462–19467, 2012; Meck, Church, & Matell in Behavioral Neuroscience, 127(5), 642, 2013), challenging the primacy of spatial-based functions to hippocampal processing. Given the presence of both spatial and temporal coding mechanisms within the hippocampus, we predicted that primarily temporal encoding strategies might also enhance memory. In two different experiments, we asked participants to learn lists of unrelated nouns using the (spatial) method of loci (i.e., the layout of their home as the organizing feature) or using two novel temporal methods (i.e., autobiographical memories or using the steps to making a sandwich). Participants’ final free recall performance showed comparable boosts to the method of loci for both temporal encoding strategies, with all three scaffolding approaches demonstrating performance well above uninstructed free recall. Our findings suggest that primarily temporal representations can be used effectively to boost memory performance, comparable to spatial methods, with some caveats related to the relative ease with which participants appear to master the spatial versus temporal methods.     

Was Kant a nonconceptualist?

I criticize recent nonconceptualist readings of Kant’s account of perception on the grounds that the strategy of the Deduction requires that understanding be involved in the synthesis of imagination responsible for the intentionality of perceptual experience. I offer an interpretation of the role of understanding in perceptual experience as the consciousness of normativity in the association of one’s representations. This leads to a reading of Kant which is conceptualist, but in a way which accommodates considerations favoring nonconceptualism, in particular the primitive character of perceptual experience relative to thought and judgment.

Grieving the Earth as Prayer

The COVID-19 pandemic is not so much a new kind of crisis as our most recent reminder of the dysfunction of human relations with the world we inhabit. This article argues that transforming our relations with other creatures begins with an examination of the call to be human: understanding the kind of creature we are and therefore how to live alongside other creatures with natures distinct from our own. It critiques the tendency to overemphasize human distinctiveness (anthropocentrism) or creatureliness (biocentrism, ecocentrism) to the detriment of our interpretations of human nature. Employing Jean-Louis Chrétien’s phenomenology of prayer as wounded speech, it proposes that climate/ecological grief mediates the tension of our distance from and intimacy with other creatures. Speech expressing grief over the world therefore re-embeds humans in our finitude and contingency while nevertheless treating human nature as containing a particular call to participate in Christ’s transforming work.     

Culture and diverging views of social events

The authors compared East Asians' and Americans' views of everyday social events. Research suggests that Americans tend to focus more on the self and to have a greater sense of personal agency than East Asians. The authors assessed whether, compared to East Asians, Americans emphasize main characters even when events do not involve the self and whether they see more agency or intentionality in actions, even when the actions are not their own. Whether East Asians would observe more emotions in everyday scenarios than would Americans also was investigated. In Study 1, Chinese and Americans read alleged diary entries of another person. Americans did focus more on main characters and on characters' intentionality. Study 2 replicated these results comparing Taiwanese and Americans on free recall of events concerning the self and of narratives and videos concerning others. Study 2 also found that Taiwanese made more comments about the emotional states of characters.     

The influence of selection test type on applicant reactions to employment testing

The impact of employment selection devices on the reactions of simulated applicants was investigated. In Study 1, 141 subjects were “failed” on either a biographical inventory, a cognitive ability test, a trainability test or a work sample test. Subjects rejected on the basis of biographical inventory scores perceived the test as less difficult, coped more adaptively, and had better moods than subjects tested with the other instruments. The biographical inventory was also seen as more fakable, but less amenable to improvement through feedback or training than the other devices. We hypothesized that differences among tests in cognitive demand is a primary cause of differences in applicant reaction. In Study 2 (N=151) the comparison of the effects of two biographical inventories to two cognitive ability tests supported our hypothesis, and replicated the findings of Study 1 across failure and success conditions.     

Savoring interventions for mothers of young children: Mechanisms linking relational savoring and personal savoring to reflective functioning

Parenting interventions can improve parenting outcomes, with widespread implications for children's developmental trajectories. Relational savoring (RS) is a brief attachment-based intervention with high potential for dissemination. Here we examine data from a recent intervention trial in order to isolate the mechanisms by which savoring predicts reflective functioning (RF) at treatment follow-up through an examination of the content of savoring sessions (specificity, positivity, connectedness, safe haven/secure base, self-focus, child-focus). Mothers (N = 147, M_age = 30.84 years, SD_age = 5.13; Race: 67.3% White/Caucasian, 12.9% other or declined to state; 10.9% biracial/multiracial, 5.4% Asian, 1.4% Native American/Alaska Native, 2.0% Black/African American; Ethnicity: 41.5% Latina) of toddlers (M_age = 20.96 months, SD_age = 2.50; 53.5% female) were randomized to four sessions of RS or personal savoring (PS). Both RS and PS predicted higher RF, but through different means. RS was indirectly associated with higher RF through greater connectedness and specificity of savoring content, while PS was indirectly associated with higher RF through greater self-focus in savoring content. We discuss the implications of these findings for treatment development and for our understanding of the emotional experience of mothers of toddlers.     

A double-blind,sham-controlled,trial of home-administered rhythmic 10-Hz median nerve stimulation for the reduction of tics,and suppression of the urge-to-tic,in individuals with Tourette syndrome and chronic tic disorder

Tourette syndrome (TS) and chronic tic disorder (CTD) are neurological disorders of childhood onset characterized by the occurrence of tics; repetitive, purposeless, movements or vocalizations of short duration which can occur many times throughout a day. Currently, effective treatment for tic disorders is an area of considerable unmet clinical need. We aimed to evaluate the efficacy of a home-administered neuromodulation treatment for tics involving the delivery of rhythmic pulse trains of median nerve stimulation (MNS) delivered via a wearable ‘watch-like’ device worn at the wrist. We conducted a UK-wide parallel double-blind sham-controlled trial for the reduction of tics in individuals with tic disorder. The device was programmed to deliver rhythmic (10 Hz) trains of low-intensity (1–19 mA) electrical stimulation to the median nerve for a pre-determined duration each day, and was intended to be used by each participant in their home once each day, 5 days each week, for a period of 4 weeks. Between 18th March 2022 and 26th September 2022, 135 participants (45 per group) were initially allocated, using stratified randomization, to one of the following groups; active stimulation; sham stimulation or to a waitlist (i.e. treatment as usual) control group. Recruited participants were individuals with confirmed or suspected TS/CTD aged 12 years of age or upward with moderate to severe tics. Researchers involved in the collection or processing of measurement outcomes and assessing the outcomes, as well as participants in the active and sham groups and their legal guardians were all blind to the group allocation. The primary outcome measure used to assess the ‘offline’ or treatment effect of stimulation was the Yale Global Tic Severity Scale–Total Tic Severity Score (YGTSS–TTSS) assessed at the conclusion of 4 weeks of stimulation. The primary outcome measure used to assess the ‘online’ effects of stimulation was tic frequency, measured as the number of tics per minute (TPM) observed, based upon blind analysis of daily video recordings obtained while stimulation was delivered. The results demonstrated that after 4-week stimulation, tic severity (YGTSS-TTSS) had reduced by 7.1 points (35 percentile reduction) for the active stimulation group compared to 2.13/2.11 points for the sham stimulation and waitlist control groups. The reduction in YGTSS–TTSS for the active stimulation group was substantially larger, clinically meaningful (effect size = .5) and statistically significant (p = .02) compared to both the sham stimulation and waitlist control groups, which did not differ from one another (effect size = −.03). Furthermore, blind analyses of video recordings demonstrated that tic frequency (tics per minute) reduced substantially (−15.6 TPM) during active stimulation compared to sham stimulation (−7.7 TPM). This difference represents a statistically significant (p < .03) and clinically meaningful reduction in tic frequency (>25 percentile reduction: effect size = .3). These findings indicate that home-administered rhythmic MNS delivered through a wearable wrist-worn device has the potential to be an effective community-based treatment for tic disorders.
