Incremental validity of the typical intellectual engagement scale as predictor of different academic performance measures

The incremental validity of the Typical Intellectual Engagement (TIE) scale (Goff & Ackerman, 1992) as a predictor of academic performance (AP) was tested over and above other established determinants of AP, namely, psychometric g (as extracted from 5 cognitive ability tests) and the Big Five personality traits, assessed by the Neuroticism-Extraversion-Openness Five Factor Inventory (Costa & McCrae, 1992). One hundred four British students were tested on arrival to university, and AP measures were collected longitudinally throughout a 3-year period. TIE, g, and Conscientiousness were the highest correlates of AP. A series of multiple-hierarchical regressions showed that TIE had significant incremental validity (over and above g and the Big Five) in the prediction of AP. Implications are discussed in light of the investment theory of intellectual competence and the utility of self-report inventories as predictors of academic achievement.     

Physiologic and motor conditioning and generalization in children with minimal brain dysfunction

Twenty-six children diagnosed as having minimal brain dysfunctions (MBD) were compared with 26 controls in a conditinoing and generalization procedure. Skin resistance, heart rate, and muscle action potentials were monitored throughout. Success involved learning which of two tones signalled the accessibility of a penny. Whereas 92 per cent of controls reached the criterion of five successive correct responses, only 62 per cent of MBD’s did. Further, a third of the MBD’s were so maladaptive as to force procedural variations, while only a few minor irregularities occurred with the controls. Quality of performance was related to age, intelligence, and ability to discriminate and remember tones. Controls were more physiologically reactive than MBD’s, especially in skin resistance. Physiologic differentiation of the two tones was significant in both groups of children and appeared concurrently with motor differentiation. The only evidence of physiologic generalization was in the SR data of controls. The possibility that defective arousal structures, or defective coupling of arousal structures and other perceptual and motor structures, could account for the decreased physiologic reactivity, short attention spans, and poor concentration ofsome MBD’s is discussed. This research, in conformity with other laboratory studies of the brain, indicates that motivational as well as cognitive defects may be organically based.     

Place and action in children's representations of stories

The purpose of the four experiments was to examine the prominence of place and action information in the story representations of second (7-year-old), fifth (10-year-old), and sixth (11-year-old) grade children and college students. The subjects were read short stories in which the information in a premise and an outcome sentence were consistent or inconsistent in describing place or action information. Judgments about story adequacy and the conditional probability of an inadequacy judgment given inconsistency detection were measures of prominence in the story representation, and prominence was manipulated by providing place titles, action titles, or no titles. The results showed that place inconsistency is more important than action inconsistency in children's judgments of story adequacy, except when the action involves the story theme. Developmental differences in story judgments generally were larger for inconsistent actions than for inconsistent places, perhaps due to children's problems in abstracting an action theme early in story processing.     

Active and passive distraction using a head-mounted display helmet: effects on cold pressor pain in children.

OBJECTIVE: The current study tested the effectiveness of interactive versus passive distraction that was delivered via a virtual reality type head-mounted display helmet for children experiencing cold pressor pain. DESIGN: Forty children, aged 5 to 13 years, underwent 1 or 2 baseline cold pressor trials followed by interactive distraction and passive distraction trials in counterbalanced order. MAIN OUTCOME MEASURES: Pain threshold and pain tolerance. RESULTS: Children who experienced either passive or interactive distraction demonstrated significant improvements in both pain tolerance and pain threshold relative to their baseline scores. In contrast, children who underwent a second cold pressor trial without distraction showed no significant improvements in pain tolerance or threshold. CONCLUSION: Although both distraction conditions were effective, the interactive distraction condition was significantly more effective. Implications for the treatment of children's distress during painful medical procedures are discussed.
