Life history theory predicts that parents will balance benefits from investment in current offspring against benefits from future reproductive investments. Long-lived organisms are therefore less likely to increase parental effort when environmental conditions deteriorate. To investigate the effect of decreased foraging capacity on parental behaviour of long-lived monogamous seabirds, we experi...

Twelve years ago I wrote an annotation for this journal entitled 'The handicapped school leaver'.1 I pointed out what many knew and Warnock has so clearly stated that 'the transition from school to adult life can be difficult for many young people. For those with special educational needs it is likely to be a period of particular stress'.2 I lamented the loss of an extra year in education which...

Assessment and management of visual disorders in children with physical and/or intellectual impairment present a complex challenge to the clinician. A comprehensive review of all aspects of vision care in multiply handicapped children is too diverse to address in a single review. This review will focus on the techniques which have been developed for visual acuity assessment in this challenging ...

Rats with X-irradiation-produced degranulation of the hippocampal dentate gyrus were trained in the acquisition and reversal of simultaneous visual and tactile discriminations in a T-maze. These experiments employed the same treatment, apparatus, and procedure but varied in task difficulty. In the brightness and roughness discriminations, the irradiated rats were not handicapped in acquiring or...

A simple simulator for evaluating the physical capabilities of severely handicapped prospective drivers was developed and evaluated. The simulator presents a two-dimensional tracking task to be carried out using the driving controls of the Scott van, which is a uni-lever servo-controlled vehicle designed for the severely impaired. Twenty-five able-bodied subjects were tested on the simulator an...

SET and the handicapped In your Autumn 1966 issue, you published a letter from Dr. Bailey, of Tone Vale Hospital, Somerset, on the adverse effect of the selective employment tax on the employment of disabled workers.

Although facial expressions of emotion are universal, individual differences create a facial expression "signature" for each person; but, is there a unique family facial expression signature? Only a few family studies on the heredity of facial expressions have been performed, none of which compared the gestalt of movements in various emotional states; they compared only a few movements in one o...

Aim This was to determine the prevalence of congenitally missing teeth in the permanent dentition among a population of disabled schoolchildren in Kuwait. Methods The study involved 702 subjects (383 males and 319 females) with sensory, physical or developmental disabilities attending the special needs schools and ranging in age from 8-29 years (mean = 13.3 years). Diagnosis and recordings were...

Humans reason about the mental states of others; this capacity is called Theory of Mind (ToM). In typically developing adults, ToM is supported by a consistent group of brain regions: the bilateral temporoparietal junction (TPJ), medial prefrontal cortex (MPFC), precuneus (PC), and anterior temporal sulci (aSTS). How experience and intrinsic biological factors interact to produce this adult fun...
