Russia and the West: The Root of the Problem of Mutual Understanding

I examine issues tied to the allegeddifficulties of mutual understanding betweenRussia and the West. I show that some of thebackground to these issues lies in thedifference of culturally grounded differencesin perceptual and conceptual schemata. In theWest, a broadly understood Aristotelianism andin Russia Neoplatonism designate dominantattitudes to the world. The Russian `lunar'consciousness, in comparison with the `solar'consciousness of the West, tends by and largeprecipitously to totalize the world, and theexperienced multiplicity of the real isreferred to its imagined center. The differencebetween Russia and the West, limited to somedegree by mutual similarities, can become thebasis of an axiological and intellectualdialogue important for one side and theother.     

Patterns of hand preference for pairs of actions and the classification of handedness

Pairs of actions such as write × throw and throw × racquet were examined for items of the Annett hand preference questionnaire (AHPQ). Right (R) and left (L) responses were described for frequencies of RR, RL, LR, and LL pairings (write × throw etc.) in a large representative combined sample with the aim of discovering the distribution over the population as a whole. The frequencies of RL pairings varied significantly over the different item pairs but the frequencies of LR pairings were fairly constant. An important difference was found between primary actions (originally write, throw, racquet, match, toothbrush, hammer with the later addition of scissors for right‐handers) and non‐primary actions (needle and thread, broom, spade, dealing playing cards, and unscrewing the lid of a jar). For primary actions, there were similar numbers of right and left writers using the ‘other’ hand. For non‐primary actions more right‐handers used the left hand than for primary actions but more left‐handers did not use the right hand. That is, different frequencies of response to primary versus non‐primary actions were found for right‐handers but not for left‐handers. The pattern of findings was repeated for a corresponding analysis of left‐handed throwing × AHPQ actions. The findings have implications for the classification of hand preferences and for analyses of the nature of hand skill.     

Solution Strategies and Achievement in Dutch Complex Arithmetic: Latent Variable Modeling of Change

In the Netherlands, national assessments at the end of primary school (Grade 6) show a decline of achievement on problems of complex or written arithmetic over the last two decades. The present study aims at contributing to an explanation of the large achievement decrease on complex division, by investigating the strategies students used in solving the division problems in the two most recent assessments carried out in 1997 and in 2004. The students’ strategies were classified into four categories. A data set resulted with two types of repeated observations within students: the nominal strategies and the dichotomous achievement scores (correct/incorrect) on the items administered.It is argued that latent variable modeling methodology is appropriate to analyze these data. First, latent class analyses with year of assessment as a covariate were carried out on the multivariate nominal strategy variables. Results showed a shift from application of the traditional long division algorithm in 1997, to the less accurate strategy of stating an answer without writing down any notes or calculations in 2004, especially for boys. Second, explanatory IRT analyses showed that the three main strategies were significantly less accurate in 2004 than they were in 1997.     

Predicting Growth Curves of Early Childhood Externalizing Problems: Differential Susceptibility of Children with Difficult Temperament

Using an accelerated longitudinal design, the development of externalizing problems from age 2 to 5 years was investigated in relation to maternal psychopathology, maternal parenting, gender, child temperament, and the presence of siblings. The sample consisted of 150 children selected at age 2–3 years for having high levels of externalizing problems. Parenting was measured using observational methods, and maternal reports were used for the other variables. Overall, mean levels of externalizing problems decreased over time, and higher initial levels (intercept) were related to a stronger decrease (negative slope) in externalizing problems. Results showed that higher levels of maternal psychopathology were related to less decrease in early childhood externalizing problems. Parental sensitive behavior predicted a stronger decrease in externalizing problems, but only for children with difficult temperaments. A stronger decrease of externalizing problems in children with older siblings also pertained only to children with difficult temperaments. Thus, temperamentally difficult children appear to be more susceptible to environmental influences on the development of externalizing behaviors. Our results indicate that the role of siblings in early childhood externalizing problems deserves more research attention, and that intervention efforts need to take into account temperamental differences in children’s susceptibility to environmental influences.     

On the minimization of task switch costs following long-term training

Flexible, context-dependent linkages between stimulus and response are fundamental to adaptive behavior. In the present article, we evaluate the limits of this flexibility by exploring the asymptotic efficiency of people’s ability to switch between two different sensorimotor mappings. Two stimulus—response (S—R) mappings were learned, either both on the same hand (unimanual condition) or one mapping per hand (intermanual condition). The S—R mappings presented bivalent stimuli and employed the same response keys. A novel training regimen successfully reduced task-switch costs to approximately 20 msec, suggesting that residual switch costs cannot be eliminated. These costs cannot be entirely attributed to the cognitive control process of task-set reconfiguration, because they are observed over cued switch intervals of several seconds. Two additional issues in motor learning were addressed: the single or dual loci of manual motor control and the coordinate system of task representation. First, the results favored the notion of independent controllers for each hand instead of a single dominant controller, since intermanual performance was superior to unimanual performance. Second, a transfer task tested internal (egocentric) and external (allocentric) coordinate systems. Transfer was more effective using the external coordinate system, suggesting that the S—R mappings reflected the association between the bivalent stimuli and external goals (i.e., the individual keys) rather than the concrete pattern of muscle contractions (i.e., the finger pressing the key). Finally, retention tests revealed that these learned S—R associations were remarkably durable, since no decrements in fluent task-switching performance were observed after 10 months without practice.     

An evaluation of three different theories of metaphor production through the use of an intentional category mistake procedure

Three current theories of metaphor production, those of atribute matching, analogical reasoning, and Gestalt perceptual processing, were tested by asking subjects to compare famous people with various categories. Three sets of instructions were devised, each reflecting one of the major theories. Results showed that while subjects could make comparisons under all conditions, they found it significantly easier to work with Gestalt instructions than with either of the other two. Gestalt instructions also produced more novel metaphoric comparisons, with such responses judged to be no less apt than statistically more conventional comparisons. Similar results did not apply to metaphoric comparisons produced under the remaining two instructional conditions where statistically novel comparisons were judged to be less apt than their more conventional counterparts. A second study was run to control for possible demand property differences among the various instructional conditions. Even with these additional controls, results of the second study replicated all major findings reported in Experiment I. Implications of these findings for the production of metaphors in more natural contexts were discussed, as were implications for creative problem-solving. In both cases it was suggested that a direct, nonananalytic approach might be more useful in revealing unexpected and important relationships between concepts than would be the case for more analytic approaches usually stressed as optimum for either metaphor production or problem solving.Visiting Research Scholar (1979–1980)     

An investigation of preconditions necessary for the introduction of a campaign to promote breast self-examination amongst Zimbabwean women

This study examines elements of the health belief model as predictors of intentions to self-examine breasts in two samples of women. Undergraduate samples from London and Harare are compared on levels of knowledge of breast cancer and breast self-examination (BSE), and on scales measuring perceived susceptibility to breast cancer, exposure to information and experience of breast cancer and perceived costs, barriers and benefits of BSE. Analysis of results indicates that an education campaign to promote awareness and the practice of BSE which incorporates factors of the health belief model could increase the number of Zimbabwean women performing this valuable preventive health behaviour.
