The relationship between personality adjustment and success in remedial programs in dyslexic children

Dyslexic and a normal group consisting of 104 children each were matched with reference to age, income, intelligence, and sex. Specific personality dimensions including self-concept, achievement motivation, general manifest anxiety, test anxiety, and behavior deviance were measured. Dyslexic children showed poorer adjustment in all areas of personality. Comparison of results within the dyslexic group showed that children who are successful in remedial training show better emotional adjustments than unsuccessful dyslexic children. A stepwise multiple regression analysis employing personality variables and overall success in remedial language training was computed. Classroom behavior and self concept were found to correlate with success and yielded a multiple correlation of .544. Results are discussed with reference to remediation and treatment.     

A Framework for Epistemological Discussion on Integrated STEM Education

Science & Education - In primary and secondary schools, the disciplines encompassed in “STEM”—Science, Technology, Engineering and Mathematics—have usually been studied...     

On 'The Myth of the Learning Society'

A recent critique by Hughes and Tight (1995) argued that the 'Learning Society' and related notions of productivity and change are 'myths'. In response, it is argued here that myth should not be confused with ideological distortion. The rhetorical dimension of current initiatives is a necessary feature of theoretical formulation, intended to influence public discussion and policy-making. The concepts of productivity and change are reconsidered in a wider historical dimension and the communitarian aspects of the project are shown to have a more positive significance in the light of, for example, recent work by Beck and Giddens on 'reflexivity' and 'risk'. It is acknowledged that faith in the application of technological solutions to societal learning challenges is frequently misplaced. But fear that the project's aims might be subverted by interests hostile to humane educational values is insufficient reason for such scepticism, which is too narrowly grounded and is misdirected.     

The role of primary reinforcement and overt movements in autoshaping in the pigeon

Following sessions of free grain delivery, a transparent shield was placed over the magazine, which made food unavailable. Different groups of pigeons then “observed” positive, zero, or negative correlations between the keylight and inaccessible grain. Keypecks were rare in all groups. Next, the shield was removed, and a transfer-test was given in which all subjects were exposed to keylight presentations followed by available grain. The previously positive group pecked sooner and more frequently than the others. A second experiment, which yielded similar results, excluded the possibility that approaches to the keylight during the observation phase had mediated learning in the first experiment. These findings were discussed in relationship to operant and Pavlovian analyses of autoshaping.     

Fear potentiation of the acoustic startle reflex using noises of various spectral frequencies as conditioned stimuli

The effectiveness of noise of various intensities and frequencies in modulating the amplitude of the acoustic startle reflex was evaluated, as a preliminary test of the capacity of these noises to produce consistent and reliable fear-potentiated startle in rats. It was determined that bands of noise containing high frequencies (greater than 10 kHz) tend to unconditionally reduce acoustic startle responses, probably by masking the high-frequency startle-eliciting stimulus. Noise containing high frequencies produced reliable fear-potentiated startle only when its estimated unconditioned startle suppression was subtracted from the enhancement obtained after pairing it with footshocks. Noises devoid of high frequencies produced modest-unconditioned startle enhancements and the most robust and reliable fear-potentiated startle when they were paired with footshocks. A nonmonotonic relationship between training shock intensity and the level of fear-potentiated startle was also exhibited when a low-frequency noise was used as a conditioned stimulus, a finding consistent with previous studies in which a visual stimulus was used. Finally, a differential Pavlovian conditioning procedure indicated that rats could readily discriminate between two different low-frequency bands of noise. The outcome of these experiments indicates that it is easier to employ low-frequency bands of noise to obtain auditory fear-potentiated startle with high-frequency startle-eliciting stimuli.
