Politics and school psychology: A case study

School psychology is one of several professions in education which offer services beyond the regular school curriculum and program. Psychologists who work in school systems have long recognized the need to cooperate with these other professionals in school settings. In addition, they have been aware of the pressures from parents, teachers, and community groups which can impinge upon their jobs. However, limited availability of funding, federally mandated services, and legislation regarding certification are rapidly placing local, state, and national politics into prominance for school psychologists. An example is provided using the Commonwealth of Kentucky.     

Long-term retention of a visually cued poison-based aversion in monkeys.

Retention of a poison-based aversion after a 3-yr. period by 8 vervet monkeys (Cercopithecus aethiops) was found. The color of the visual cue appeared to effect the retention of the aversion.     

Effects of selective forebrain noradrenaline loss on behavioral inhibition in the rat.

Virtually total depletion of cortical and hippocampal noradrenaline by stereotaxic injection of 6-hydroxydopamine into the fibers of the dorsal noradrenergic bundle produced no impairment in acquisition learning of a runway response for food reward. Extinction of this response, once learned, was markedly slower in the treated group than in controls, the treated animals perseverating in rapid running to the goal box even with no food present there. Similarly, no impairment was found on acquisition of a continuously reinforced lever-pressing response for food. Extinction of this response, however, was again slower in the treated group. Subsequent acquisition of a successive light-dark discrimination task was also slower in the treated group, with these animals perseverating in responding to the negative stimulus. Although selective forebrain noradrenaline loss does not impair the acquisition of appetitive responses, the suppression of responses in the absence of reward is impeded. A parallel is drawn with those effects found classically after surgical lesion to the hippocampus.     

Digital computer estimation of eye fixations

A method is presented for estimating eye fixations to the degree of accuracy desired. In the process, the quantity of data is greatly reduced so that analysis can be accomplished at the end of each experimental run. The algorithm is particularly suitable for “slow” computers because the analog-to-digital conversion rate can be low and because the data reduction process decreases the number of calculations required to obtain the analytical results.     

MEMORY WALLET INTERVENTION IN AN ADULT DAY-CARE SETTING

The use of memory wallets to prompt factual information during conversations with day-care center volunteers was evaluated for four subjects with dementia. Memory wallets contained 15–20 pictures and sentences about familiar persons, places, and events that each subject had difficulty remembering. All subjects used the memory wallets to improve their conversations by increasing factual statements and decreasing ambiguous, unintelligible, and perseverative utterances. Volunteers decreased their use of questions and prompts during conversations in which subjects used their memory wallets. These results demonstrate the effectiveness of using volunteers to develop memory wallets and to encourage their use during conversations with day-care clients.
