School achievement strongly predicts midlife IQ

The relationship between measures of IQ and standardized school achievement tests is well established at around r ≈ 0.5 when the two are measured in close proximity. The current paper examined the stability of this correlation when comparing elementary school achievement (grades 3–8) and midlife IQ. Iowa Adoption Study participants who had standardized school achievement measures (ITBS) on file were given the WAIS-III. Mean age at IQ testing was 44.01 years (SD 6.65 years). The correlation between school achievement and WAIS-III FSIQ was r = 0.64, suggesting substantial life span stability in this relationship. Furthermore, elementary school achievement was substantially correlated with occupational status and household income at midlife. These findings suggest that standardized school achievement data is a useful measure of premorbid IQ.     

The influence of a long term exercise program on lower limb movement variability and walking performance in patients with peripheral arterial disease

The purpose of this study was to examine the effects of a 12 month exercise program on lower limb movement variability in patients with peripheral arterial disease (PAD). Participants (n = 21) with an appropriate history of PAD and intermittent claudication (IC) volunteered for this study and were randomly allocated to either a control group (CPAD–IC) (n = 11), which received normal medical therapy and a treatment group (TPAD–IC) (n = 10), which received normal medical therapy treatment and a 12 month supervised exercise program. All participants underwent 2D joint angular kinematic analysis during normal walking to assess lower limb movement variability and walking speed. Between-group differences were analyzed via mixed measures ANOVA. The 12 month supervised exercise program made no significant impact on the lower limb movement variability or walking speed of the TPAD–IC group as determined by either intralimb joint coordination or single joint analysis techniques. Long term supervised exercise programs do not appear to influence the lower limb movement variability of PAD–IC patients.     

A microcomputer package for real-time skin conductance response analysis

A suite of programs has been developed to acquire data from a commercially available, highquality skin conductance meter, via a standard IEEE bus, on an Apple II or Apple lie microcomputer. These programs score and analyze stimulus-evoked skin conductance responses in a preset time window, and store the resultant data on disk, if required. Facilities for a manual override of the automatic scoring routine are available. The setup offers a method of scoring data as they are acquired; it uses currently recommended standards for skin conductance analysis and allows a high magnification of responses, without any need for continual monitoring, because of hardware facilities that automatically “back-off” a subject’s tonic skin conductance level.     

A COMPARISON OF RESPONSES BETWEEN INDIAN AND EUROPEAN SOUTH AFRICANS TO THE TMAS

Cross-cultural anxiety research has generally used translated forms of inventories such as Taylor's M.A.S. and Spielberger's S.T.A.I., checking only for semantic equivalence and ignoring the problems of item content and typical response modes. In order to clarify this approach, the 50 item M.A.S. was administered to groups of South African Europeans and South African Indians, both of which were varied on an educational dimension. Results suggest that the two groups vary in response, but that this variation decreases with educational level.     

The mediating and moderating role of planning on mothers’ decisions for early childhood dietary behaviours

Objective: Examine the roles of action and coping planning on the intention–behaviour relationship for mothers’ decisions for their young children’s dietary behaviours.

Design: Prospective design with two waves of data collection, one week apart.

Main outcome measures: Mothers (N = 197, M_age = 34.39, SD = 5.65) of children aged 2–3 years completed a main questionnaire assessing planning constructs and intentions, and a one-week follow-up of the target behaviours – ‘healthy eating’ and ‘discretionary choices’.

Results: Intention was the strongest predictor of behaviour for both dietary behaviours. For healthy eating, intention moderated the indirect relationship between intention–behaviour via planning; coping planning was less important when intention was strong. Further, intention was not a direct predictor of behaviour when intention was relatively low. Action planning was not a direct predictor of either behaviour after accounting for intention and coping planning; action planning on behaviour was mediated by coping planning (only for healthy eating). Intention was not a direct predictor of coping planning; intention on coping planning was mediated by action planning. Neither type of planning predicted discretionary choices.

Conclusion: Current findings contribute novel information on the mechanisms underpinning the effect of action and coping planning on the intention–behaviour relationship.     

Constructive Logic with Strong Negation is a Substructural Logic. II

The goal of this two-part series of papers is to show that constructive logic with strong negation N is definitionally equivalent to a certain axiomatic extension NFL _ew of the substructural logic FL _ew . The main result of Part I of this series [41] shows that the equivalent variety semantics of N (namely, the variety of Nelson algebras) and the equivalent variety semantics of NFL _ew (namely, a certain variety of FL _ew -algebras) are term equivalent. In this paper, the term equivalence result of Part I [41] is lifted to the setting of deductive systems to establish the definitional equivalence of the logics N and NFL _ew . It follows from the definitional equivalence of these systems that constructive logic with strong negation is a substructural logic. Presented by Heinrich Wansing     

Asymmetrical cross-language priming effects

Three experiments were conducted to examine cross-language priming in bilinguals. The first was a cross-language primed lexical decision task experiment with Chinese-English bilinguals. Subjects made lexical decisions about primary associate targets in the two languages at the same rate, but priming occurred only when the prime was in their first language (L1), Chinese, and the target was in their second language (L2), English. Experiment 2 produced the same pattern of asymmetrical priming with two alphabetic languages, French and Dutch. In Experiment 3, the crucial stimuli were translation equivalents. In contrast to the results of Experiments 1 and 2, priming occurred across languages in both the L1-L2 and L2-L1 conditions. However, this priming was also asymmetrical, with more priming occurring in the L1-L2 condition. A tentative separate-interconnected model of bilingual memory is described. It suggests that the representations of words expressed in different languages are stored in separate memory systems, which may be interconnected via one-to-one links between same translation-equivalent representations as well as meaning-integration processes.     

Anxiety responses in a sample of South African Indians

As much cross-cultural anxiety work has focused on ensuring only the semantic equivalence of questionnaires in different languages, this study examines the response characteristics of South African Indians to an anxiety instrument tentatively constructed for this population. Results show that the scale has a fairly high degree of internal consistency, and that certain items were regularly reported to be frequently experienced. Factor analysis of the 26 items reveals a cognitive distress factor, and a possible distinction within the physiological/physical dimension between somatic distress and elevated activity.
