Deontic and epistemic reasoning in children revisited: Comment on Dack and Astington

Dack and Astington (Journal of Experimental Child Psychology 110 2011 94–114) attempted to replicate the deontic reasoning advantage among preschoolers reported by Cummins (Memory & Cognition 24 1996 823–829) and by Harris and Nuñez (Child Development. 67 1996 572–1591). Dack and Astington argued that the apparent deontic advantage reported by these studies was in fact an artifact due to a methodological confound, namely, inclusion of an authority in the deontic condition only. Removing this confound attenuated the effect in young children but had no effect on the reasoning of 7-year-olds and adults. Thus, removing reference to authority “explains away” young children’s apparent precocity at this type of reasoning. But this explanation rests on (a) a misunderstanding of norms as targets of deontic reasoning and (b) conclusions based on a sample size that was too small to detect the effect in young children.     

The Effects of Hand Gestures on Verbal Recall as a Function of High- and Low-Verbal-Skill Levels

The author examined the effects of cueing for verbal recall with the accompanying self-generated hand gestures as a function of verbal skill. There were 36 participants, half with low SAT verbal scores and half with high SAT verbal scores. Half of the participants of each verbal-skill level were cued for recall with their own gestures, and the remaining half was given a free-recall test. Cueing with self-generated gestures aided the low-verbal-skill participants so that their retrieval rate equaled that of the high-verbal-skill participants and their loss of recall over a 2-week period was minimal. This effect was stable for both concrete and abstract words. The findings support the hypothesis that gestures serve as an auxiliary code for memory retrieval.     

Hemispheric Differences in the Processing of Words Learned Early Versus Later in Childhood

The research investigated whether there are hemispheric differences in processing for words acquired early in childhood (early AoA) and words acquired later in childhood (late AoA). We hypothesized that because of recent evidence suggesting that there is a right hemisphere dominance in early childhood, early AoA words would be represented in the right hemisphere, and late AoA words would be represented in the left hemisphere. This hypothesis differs from an early view that late AoA words would be represented in the left hemisphere, and early AoA words would be represented in both hemispheres (Gazzaniga, 1974). We report two experiments using the divided visual field (DVF) technique. The results showed that there was a right visual field (RVF)/left hemisphere (LH) advantage only for late AoA words. For early AoA words, there was a left visual field (LVF)/right hemisphere advantage (RH). Implications for theories of hemispheric differences in word processing are discussed.     

Two Factors to be Considered in the Design of Experiments in Anxiety and Motor Behavior

The authors examined the influence that attentional focus on either a postural or a suprapostural task had on the performance of each task. Participants (N = 32) stood on an inflated rubber disk and held a pole horizontally. All participants performed under 4 attentional focus conditions: external (disk) or internal (feet) focus on the postural task, and external (pole) or internal (hands) focus on the suprapostural task. Compared with internal focuses, external focuses on either task resulted in similar and reduced postural sway. Response frequency on each task increased when participants focused on the respective task. Finally, an external focus on either task produced higher frequencies of responding on the suprapostural task. The authors conclude that suprapostural task goals have a stronger influence on postural control than vice versa, reflecting the propensity of the motor system to optimize control processes on the basis of the desired movement effect.     

How accurate are women's estimates of date of onset of next menses?

Abstract

Because of individual differences in Occurrence of ovulation and patterns of hormonal secretions, one would usually prefer to measure locus in the menstrual cycle using physiological assessment procedures. But such methods are time consuming and costly. When exploring a new domain for possible relations to the menstrual cycle, it would be cost effective to use the simpler procedure of having each women verbally estimate date of onset of next menses. The accuracy of such estimates was studied in two college age samples. Estimated number of days until next onset correlated highly with actual number of days, as verified by follow-up (r = 0.90). As a group, women neither under- nor overestimated number of days. The precision with which these judgments were made was reasonably high. In sum, when a group of women are followed for one cycle, the average accuracy is very high, certainly high enough to support use of such verbal reports for certain scientific purposes.     

The Factor Structure of the CVLT-C in Pediatric Epilepsy

The current study used archival data to evaluate the fit of six latent variable models, originally generated by Donders (1999) Donders. 1999. Structural analysis of the California Verbal Learning Test—Children's Version in the standardization sample. Developmental Neuropsychology, 15(3): 395–406. [CSA][Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], for the California Verbal Learning Test-Children's Version (CVLT-C; Delis, Kramer, Kaplan, &; Ober, 1994 Delis, D. C., Kramer, J. H., Kaplan, E. and Ober, B. A. 1994. California Verbal Learning Test—Children's Version, San Antonio, TX: Psychological Corporation.  [Google Scholar]) in a large (N = 289) sample of pediatric epilepsy cases presenting at three tertiary treatment centers. Using confirmatory factor analysis, we found that a model including factors of Attention Span, Learning Efficiency, Free Delayed Recall, Cued Delayed Recall, and Inaccurate Recall demonstrated the best relative fit for our data. These findings are consistent with those reported by Donders (1999) Donders. 1999. Structural analysis of the California Verbal Learning Test—Children's Version in the standardization sample. Developmental Neuropsychology, 15(3): 395–406. [CSA][Taylor &; Francis Online], [Web of Science ®] , [Google Scholar] in his reanalysis of the CVLT-C standardization sample data, supporting the validity of this factorial model in pediatric epilepsy populations.     

Postintentional Neglect

F. Mechsner (2004) seems to deny a functional importance of postintentional processes, except that their characteristics can be taken into account at the perceptual-cognitive level of control. In that perspective, processes that are critical for the understanding of motor control and its limitations are neglected. On the other hand, the functional importance of task conceptions or task sets, which can vary and affect performance even for tasks that appear identical to an observer, is emphasized.     

Using the stimulus equivalence paradigm to teach course material in an undergraduate rehabilitation course

In 2 experiments, we examined whether the stimulus equivalence instructional paradigm could be used to teach relations among names, definitions, causes, and common treatments for disabilities using a selection-based intraverbal training format. Participants were pre- and posttested on vocal intraverbal relations and were trained using multiple-choice worksheets in which selection-based intraverbal relations were taught and feedback was delivered until mastery. Most participants in Experiment 1 showed the emergence of vocal intraverbal relations, but responding did not generalize to final written intraverbal tests. Participants in Experiment 2 showed the emergence of not only vocal intraverbal relations but also written intraverbal relations on final tests. Results suggest that the stimulus equivalence paradigm can be effectively implemented using a selection-based intraverbal training format, the protocol may be an effective means of emphasizing important concepts in a college course, and emergent skills may generalize to novel response topographies.     

The roles of private speech and inner speech in planning during middle childhood: Evidence from a dual task paradigm

Children often talk themselves through their activities, producing private speech that is internalized to form inner speech. This study assessed the effect of articulatory suppression (which suppresses private and inner speech) on Tower of London performance in 7- to 10-year-olds, relative to performance in a control condition with a nonverbal secondary task. Experiment 1 showed no effect of articulatory suppression on performance with the standard Tower of London procedure; we interpret this in terms of a lack of planning in our sample. Experiment 2 used a modified procedure in which participants were forced to plan ahead. Performance in the articulatory suppression condition was lower than that in the control condition, consistent with a role for self-directed (private and inner) speech in planning. On problems of intermediate difficulty, participants producing more private speech in the control condition showed greater susceptibility to interference from articulatory suppression than their peers, suggesting that articulatory suppression interfered with performance by blocking self-directed (private and inner) speech.
