Typical and Atypical Development of Visual Attention in 3‐ to 9‐Month‐Old Infants
The interactions between attention and stimulus encoding in infancy were examined using heart rate ( HR ) and visual habituation measures. At 3, 6, and 9 months of age, infants ( N = 119) were habituated to an adult face; longest look ( LL ) duration was measured as an indicator of encoding speed. Three groups were formed based on LL change from 3 to 9 months: Large Decrease, Small Decrease, and Increase. Using concurrent electrocardiograph recor…
Infant responsiveness, alertness, haemoglobin and growth in rural Sidama, Ethiopia
Several recent studies have supported relations between infant behaviour (alertness and responsiveness) and nutrition in addition to investigating infant behaviour within the context of changes in iron status over time. Existing research is typically limited to the investigation of the effects of a single vitamin or mineral, and no studies have been found that examined the influence that early alertness and responsiveness have on growth in early …
The Men Who Would Not March
Those texts which have paid any attention to the surrender of the copper mining centre of Concordia in Namaqualand to General Smuts in April 1902, invariably blame this ‘disgrace’ on the cowardice of the elderly commandant, Captain F. Phillips, manager of the Concordia mine. Using documents retrieved from the South African National Archives, the authors argue that in fact the main reason for the surrender was a mutiny by the 100-odd coloured memb…
Event-Related Potential and Behavioral Measures of Attention in 5-, 7-, and 9-Year-Olds
In 2 experiments, the development of auditory selective attention in children was assessed. The participants, aged 5, 7, and 9 years, responded to target stimuli in the left ear for 1 series (ignoring the standard stimuli) and in the right ear for the other series. In Experiment 1, event-related potentials (ERPs) evoked by the auditory stimuli were recorded from frontal, central, and parietal sites. The 9-year-olds showed a greater processing neg…
Bioelectrical Potentials of Philodendron Cordatum
We explored the prospect of using the bioelectrical potentiaLs of Philodendron cordatum as a new method for studying the behavior of plants. The bioelectrical potentials were recorded from equipment typically associated with EEG recordings. Plants were exposed to a 6-hr. training period of light only, dark only, or alternating 1-min. periods of light/dark. Following training, all plants were exposed to a 10-min. testing period in darkness during …

Event-related potential measures of 24-hour retention in 5-month-old infants
Two experiments using event-related potentials (ERPs) investigated 24-hr recognition memory in infants. In each, ERPs were recorded to 100 identical stimuli in 5-month-olds. After 24 hr, 50 of these familiar stimuli and 50 novel stimuli were presented. In Experiment 1, the 2 stimuli were a tone and a click. The amplitude of a negative peak (N2 ; approximate latency = 350 ms) of the auditory ERP was larger on Day 2 for the familiar stimuli compare…
