Polydipsia induced by intermittent delivery of salted liquid foods

Food-deprived rats given constant access to water were exposed to fixed-time presentations of soybean milk and diluted sweetened condensed cows' milk. In some conditions these liquid foods were adulterated with varying amounts of sodium chloride. Under a fixed-time 30-sec schedule of food delivery, little water was consumed when the food was soybean milk alone, or soybean milk with sodium chloride added in concentrations of .9, 1.8, or 3.6%. However, schedule-induced polydipsia appeared when soybean milk adulterated with 7.2 or 14.4% sodium chloride was delivered under this schedule. When soybean milk containing 7.2% sodium chloride was presented under fixed-time 15-, 30-, 60-, 120-, and 240-sec schedules, schedule-induced drinking increased with the fixed-time value from 15 to 120 seconds, and decreased at 240 seconds. Like soybean milk, diluted sweetened condensed milk delivered under fixed-time schedules of 30, 60, and 120 seconds failed to evoke schedule-induced polydipsia, but did so when adulterated with 7.2% sodium chloride. Drinking induced by salted liquid foods resembled the polydipsia engendered by spaced dry-food presentations in several ways, including temporal relation to food delivery, persistence within and across sections, sensitivity to interfood interval, and magnitude relative to intake evoked by bulk-food presentation.     

Cortical evoked responses to synonyms and antonyms

The brain’s processing of synonymity and antonymy was explored by examining the cortical evoked responses to correct judgments that a test word was a synonym or an antonym of a standard word presented 1 sec previously. Each of five subjects judged 256 pairs of words in each of two sessions. The evoked response to the second word was averaged separately for synonym and antonym pairs. Presentation of each test word as a synonym or an antonym, the order of presentation of each pair, and the side of the “synonym” response key were counter-balanced within subjects. The difference between the averaged response to antonym test words and that to synonym test words differed biphasically over the interval 250-650 msec after the stimulus. The demonstration of an evoked response difference between synonyms and antnyms extends the applicability of evoked potentials from attributes of individual word meaning to the semantic relationships between words.     

Recognition memory for related pictures

This study presents a test of the notion of semantic integration of information m pictures. In Experiment 1. subjects were presented pictures which comprised various subsets of the elements in one of four standard pictures. In the test phase. recognition confidence tor old and new items was a direct function of the number of figures in the test picture. However. recognition confidence was significantly higher for old than for new pictures, contrary to predictions of the integration model of Bransford and Franks (1971). In Experiment 2, the differential predictions of the integration model and the tally model (Reitman & Bower, 19731 were tested. The information for a key standard picture was presented solely as ONEs during acquisition. For the other three standard pictures. information was presented as ONEs, TWOs, and THREEs. The results were that recognition confidence increased with complexity at the test item with regular items but decreased with increasing complexity with key items. Together. these experiments support the tally model and demonstrate the generalizabilitv of this model to handle pictorial materials. Implications regarding the nature of picture memory are also discussed.     

New uses for the on-line computer medium in mental health care

A number of research projects related to new uses for computers in mental health service delivery are presented. These projects include work on software psychology, new computer applications in mental health care, and studies relating to the successful implementation of technology in mental health settings. Emphasis is placed on developing a better understanding of appropriate uses of technology rather than merely describing new applications.     

Telephone counsellors' conceptualising abilities and counselling skills

Telephone counsellors must make accurate assessments of callers' needs so as to provide appropriate counselling help or referral. But few researchers have examined counsellors' conceptualising abilities in relation to their counselling skill. Two studies involving telephone counsellors were carried out. The first relied on counsellors' post-interview conceptualisations of callers' problems and needs and found no link between the accuracy of these conceptualisations and counselling skill. The second used Kagan's Interpersonal Process Recall (IPR) to retrieve counsellors' conceptualisations made during the course of their interviews. The accuracy of these conceptualisations-in-action was related to level of counselling skill. Implications for training and research are discussed     

Near-death utopias: Now or later?

By viewing near-death experiences (NDEs) in the context of the quest for an ideal society, Kellehear offered hope for positive social change and insight into the social, rather than purely personal, meanings of the NDE. However, his approach raised issues of the interpretive research process generally. As with any research, near-death studies are influenced by investigators' questions, interests, and assumptions. Despite the reasoning behind Kellehear's position, he grounded his analysis not in the data, but rather in his typology of ideal societies. I suggest we look first for indications of ideal social order in near-death narratives and only later compare them with types of utopias.

How gender-expectancy affects the processing of “them”

How sensitive is pronoun processing to expectancies based on real-world knowledge and language usage? The current study links research on the integration of gender stereotypes and number-mismatch to explore this question. It focuses on the use of them to refer to antecedents of different levels of gender-expectancy (low–cyclist, high–mechanic, known–spokeswoman). In a rating task, them is considered increasingly unnatural with greater gender-expectancy. However, participants might not be able to differentiate high-expectancy and gender-known antecedents online because they initially search for plural antecedents (e.g., Sanford & Filik), and they make all-or-nothing gender inferences. An eye-tracking study reveals early differences in the processing of them with antecedents of high gender-expectancy compared with gender-known antecedents. This suggests that participants have rapid access to the expected gender of the antecedent and the level of that expectancy.     

Pedagogy for diversity: mediating between tradition and equality in schools

The aim of this paper is to provide evidence‐based guidance for educational practitioners and, in particular, for those in leadership positions in schools, on good practice in developing and implementing school level strategies and actions to promote an appreciation of diversity in schools and society.     

Consumer decision making in low‐income families: The case of conflict avoidance

• This paper explores consumer decision making in low‐income families. The focus is on the issue of conflict avoidance within the family when making consumption choices. Whereas previous studies have focused on conflict resolution strategies, this paper considers the ways in which families prevent conflict from arising in the first instance. These include individual control in purchasing and budgeting decisions, giving in to the requests of children and ensuring open communication about the family's financial situation. Importantly, the connections between the poverty narrative and the family decision making narrative are considered as the decision making strategies employed are not only aimed at avoiding conflict but also making experiences of poverty more manageable.
