“…The overlap between our current study and the previous LTM study using analogous tasks and materials lends weight to the notion of scale‐invariance in memory mechanisms [Brown et al, 2007], as have been previously demonstrated in free recall tasks, where the rate of item recall was unvarying across recall span (day, week, year) and even across from the past to the prospective future [Maylor et al, 2001]. Those previous behavioral findings imply that scale‐invariance is a form of self‐similarity in that the holistic pattern can exist at multiple levels of magnification [and even across different memory systems, e.g., Maylor, 2002].…”

We investigated the neural correlates supporting three kinds of memory judgments after very short delays using naturalistic material. In two functional magnetic resonance imaging (fMRI) experiments, subjects watched short movie clips, and after a short retention (1.5–2.5 s), made mnemonic judgments about specific aspects of the clips. In Experiment 1, subjects were presented with two scenes and required to either choose the scene that happened earlier in the clip (“scene‐chronology”), or with a correct spatial arrangement (“scene‐layout”), or that had been shown (“scene‐recognition”). To segregate activity specific to seen versus unseen stimuli, in Experiment 2 only one probe image was presented (either target or foil). Across the two experiments, we replicated three patterns underlying the three specific forms of memory judgment. The precuneus was activated during temporal‐order retrieval, the superior parietal cortex was activated bilaterally for spatial‐related configuration judgments, whereas the medial frontal cortex during scene recognition. Conjunction analyses with a previous study that used analogous retrieval tasks, but a much longer delay (>1 day), demonstrated that this dissociation pattern is independent of retention delay. We conclude that analogous brain regions mediate task‐specific retrieval across vastly different delays, consistent with the proposal of scale‐invariance in episodic memory retrieval.

“…Note that the value of c was the same for all list lengths; that is, all 90 data points are being accounted for by a single free parameter. 2 SIMPLE produces the appropriate position error gradients for operation span using the same core ideas implemented to account for recall in standard serial recall tasks and tasks thought to tap other memory systems including sensory, short-term, working, and long-term memory (see Brown et al, 2007;. The distractor activity in the operation span task serves the same function as in the continual distractor task: it spaces the to-be-remembered items out in time, and it is the distinctiveness of each item, relative to its near neighbors, at the time of test that determines recall probability.…”

Three memory tasks-Brown-Peterson, complex span, and continual distractor-all alternate presentation of a to-be-remembered item and a distractor activity, but each task is associated with a different memory system, short-term memory, working memory, and long-term memory, respectively. SIMPLE, a relative local distinctiveness model, has previously been fit to data from both the Brown-Peterson and continual distractor tasks; here we use the same version of the model to fit data from a complex span task. Despite the many differences between the tasks, including unpredictable list length, SIMPLE fit the data well. Because SIMPLE posits a single memory system, these results constitute yet another demonstration that performance on tasks originally thought to tap different memory systems can be explained without invoking multiple memory systems.

“…Unfortunately, the nature of the context is controversial. Alternative suggestions include time, temporal position within a list, list position, and position from the ends of the list (see Botvinick & Plaut, 2006;Brown, Neath, & Chater, 2007;Brown, Preece, & Hulme, 2000;Burgess & Hitch, 1999;Farrell & Lewandowsky, 2002Grossberg & Pearson, 2008;Henson, Norris, Page, & Baddeley, 1996;Lewandowsky & Farrell, 2008).…”

This article extends psychological methods and concepts into a domain that is as profoundly consequential as it is poorly understood: intelligence analysis. We report findings from a geopolitical forecasting tournament that assessed the accuracy of more than 150,000 forecasts of 743 participants on 199 events occurring over 2 years. Participants were above average in intelligence and political knowledge relative to the general population. Individual differences in performance emerged, and forecasting skills were surprisingly consistent over time. Key predictors were (a) dispositional variables of cognitive ability, political knowledge, and openmindedness; (b) situational variables of training in probabilistic reasoning and participation in collaborative teams that shared information and discussed rationales (Mellers, Ungar, et al., 2014); and (c) behavioral variables of deliberation time and frequency of belief updating. We developed a profile of the best forecasters; they were better at inductive reasoning, pattern detection, cognitive flexibility, and open-mindedness. They had greater understanding of geopolitics, training in probabilistic reasoning, and opportunities to succeed in cognitively enriched team environments. Last but not least, they viewed forecasting as a skill that required deliberate practice, sustained effort, and constant monitoring of current affairs. A t APA, we understand how challenging it can be for you to stay abreast of the latest and best academic research on psychology.
