Research byte: Simple addition problem solving may be autmoatic counting procedures and not quick retrieval from long-term memory

File under Gq, Glr, and Gr as per CHC model

 Fast automated counting procedures in addition problem solving: When are they used and why are they mistaken for retrieval?


Highlights

It is universally assumed that the answer of small additions is retrieved from memory.
Contrariwise, we replicate that they are solved by automated compacted procedures.
Moreover, we show here that these procedures are limited to operands up to 4.
Counterintuitively, RTs suggest that retrieval could be used for larger additions.
Compacted procedures are faster than retrieval and consequently mistaken for it.

Abstract

Contrary to a widespread assumption, a recent study suggested that adults do not solve very small additions by directly retrieving their answer from memory, but rely instead on highly automated and fast counting procedures (Barrouillet & Thevenot, 2013). The aim of the present study was to test the hypothesis that these automated compiled procedures are restricted to small quantities that do not exceed the size of the focus of attention (i.e., 4 elements). For this purpose, we analyzed the response times of ninety adult participants when solving the 81 additions with operands from 1 to 9. Even when focusing on small problems (i.e. with sums ⩽10) reported by participants as being solved by direct retrieval, chronometric analyses revealed a strong size effect. Response times increased linearly with the magnitude of the operands testifying for the involvement of a sequential multistep procedure. However, this size effect was restricted to the problems involving operands from 1 to 4, whereas the pattern of response times for other small problems was compatible with a retrieval hypothesis. These findings suggest that very fast responses routinely interpreted as reflecting direct retrieval of the answer from memory actually subsume compiled automated procedures that are faster than retrieval and deliver their answer while the subject remains unaware of their process, mistaking them for direct retrieval from long-term memory.

Brain/cognitive training programs and transfer: More support for changes in attentional control (AC) being a possible domain-general explanatory mechanism across programs

Another research review article that supports my hypothesis, which was invoked to explain the impact of Interactive Metronome (IM)on cognitive outcomes, that the primary mechanism of successful brain fitness or training programs may be the degree to which each program focuses on strengthening attention control (AC in CHC theory; aka, focus).  My report/white paper can be found here.  Additional information (including You Tube video presentation) available here.


The Mechanisms of Far Transfer From Cognitive Training: Review and Hypothesis.
Greenwood, Pamela M.; Parasuraman, Raja Neuropsychology, Nov 16 , 2015, No Pagination Specified. http://dx.doi.org.ezp1.lib.umn.edu/10.1037/neu0000235

Abstract

  • Objective: General intelligence is important for success in daily life, fueling interest in developing cognitive training as an intervention to improve fluid ability (Gf). A major obstacle to the design of effective cognitive interventions has been the paucity of hypotheses bearing on mechanisms underlying transfer of cognitive training to Gf. Despite the large amounts of money and time currently being expended on cognitive training, there is little scientific agreement on how, or even whether, Gf can be heightened by such training. Method: We review the relevant strands of evidence on cognitive-training-related changes in (a) cortical mechanisms of distraction suppression, and (b) activation of the dorsal attention network (DAN). We hypothesize that training-related increases in control of attention are important for what is termed far transfer of cognitive training to untrained abilities, notably to Gf. Results: We review the evidence that distraction suppression evident in behavior, neuronal firing, scalp electroencephalography, and hemodynamic change is important for protecting target processing during perception and also for protecting targets held in working memory. Importantly, attentional control also appears to be central to performance on Gf assessments. Consistent with this evidence, forms of cognitive training that increase ability to ignore distractions (e.g., working memory training and perceptual training) not only affect the DAN but also affect transfer to Gf. Conclusions: Our hypothesis is supported by existing evidence. However, to advance the field of cognitive training, it is necessary that competing hypotheses on mechanisms of far transfer of cognitive training be advanced and empirically tested.

"Just say no" to race- or demographically-adjusted IQ norms in the Dx of ID: Post made at ICDP sister blog



Previously, I coauthored an IAP Psychometric Brief (#14) with Dr. Dale Watson on the inappropriate use of "demographically adjusted norms" (aka, the Heaton norms) to adjust IQ scores upward based on an individuals race.  I was pleased last week to see a law review article devoted to this practice--an article that also concludes that the use of "ethnic" or "race" or "demographically" adjusted norms are inconsistent with scientific and legal principles.

The excellent American University Law Review article (IQ, INTELLIGENCE TESTS, “ETHNIC ADJUSTMENTS” AND ATKINS) is by Robert Sanger (click here to view).
