A clinical trial of continuous, intermittent and overlearning ‘bell and pad’ treatments for nocturnal enuresis

Sixty-one enuretic children were allocated sequentially to ‘standard’, ‘intermittent’ or ‘overlearning’ bell and pad treatment. The results suggest that the ‘overlearning’ modification of standard treatment was successful in bringing about a reduction in the relapse rate. The present status and implications of research into nocturnal enuresis were discussed in the light of the results of the investigation.     

Blocking as a function of novelty of CS and predictability of UCS

Kamin (1969) reported that after rats had been trained with one CS predicting shock, they learned virtually nothing about a second CS added to the first to form a compound--provided that the shock remained unchanged. If, however, the shock was either increased or omitted at the same time that the new CS was added, it acquired significant excitatory or inhibitory strength. Both these results were confirmed in the present experiment. In addition, however, it was found that this excitatory or inhibitory conditioning to the added element could itself be blocked if the shock remained unchanged for the first four trials after the addition of the new element. This finding implies that blocking is not due to any limitation on attentional or associative capacity, but rather occurs when subjects learn that a particular stimulus is redundant, i.e. that it predicts no change in reinforcement.     

Collateral Reports and Cross-Informant Agreement about Adult Psychopathology in 14 Societies

To advance international mental health assessment, instruments that have been internationally validated are needed. To this end, we analyzed ratings from 14 societies on the Adult Behavior Checklist (ABCL), a collateral-report form parallel to the Adult Self-Report (ASR; Achenbach and Rescorla 2003) for ages 18 to 59. Both the ABCL and the ASR assess problems, personal strengths, and adaptive functioning. For a sample of 8322 see note below collaterals, we found strong consistency across societies regarding which ABCL problem items tended to obtain relatively low, medium, or high ratings. Most societal effect sizes (ESs) for problem scale scores were small to medium (< 13.9 %), but the ES for the ABCL Personal Strengths scale was 25 %. For most of the same participants (N = 8,302), we analyzed cross-informant agreement between self-reports on the ASR and collateral reports on the ABCL. Cross-informant correlations for problem scale scores averaged .47, with considerable societal variation. Problem score means were higher on the ASR than the ABCL in every society, but the size of the difference varied across societies. Mean item ratings on the ABCL and ASR were highly correlated within every society (mean r = .92), but within-dyad item rating agreement varied widely in every society (mean r = .39). In all societies, non-corroboration of self-reported deviance and of collateral-reported deviance was common. Overall findings indicated considerable similarity but also some important differences in collateral-reported problems and adaptive functioning across 14 societies.     

Why are familiar-only experiences more frequent for voices than for faces?

Hanley,Smith, and Hadfield (1998) showed that when participants were asked to recognize famous people from hearing their voice , there was a relatively large number of trials in which the celebrity's voice was felt to be familiar but biographical information about the person could not be retrieved. When a face was found familiar, however, the celebrity's occupation was significantly more likely to be recalled. This finding is consistent with the view that it is much more difficult to associate biographical information with voices than with faces. Nevertheless, recognition level was much lower for voices than for faces in Hanleyet al.'s study,and participants made significantly more false alarms in the voice condition. In the present study, recognition performance in the face condition was brought down to the same level as recognition in the voice condition by presenting the faces out of focus. Under these circumstances, it proved just as difficult to recall the occupations of faces found familiar as it was to recall the occupations of voices found familiar. In other words, there was an equally large number of familiar-only responses when faces were presented out of focus as in the voice condition. It is argued that these results provide no support for the view that it is relatively difficult to associate biographical information with a person's voice. It is suggested instead that associative connections between processing units at different levels in the voice-processing system are much weaker than is the case with the corresponding units in the face-processing system. This will reduce the recall of occupations from voices even when the voice has been found familiar. A simulation was performed using the latest version of the IAC model of person recognition (Burton, Bruce, & Hancock, 1999) which demonstrated that the model can readily accommodate the pattern of results obtained in this study.     

Identity in Action: Predictors of Feminist Self-Identification and Collective Action

The present study sought to explore how women's life experiences influenced their beliefs, and how those beliefs in turn influenced feminist self-identification. Additionally, we sought to determine whether feminist self-identification led to increased collective action on behalf of women. Female participants (N?=?282) from two US college campuses and online listservs completed an online survey assessing feminist self-identification, collective action, and life experiences. Conservative, liberal, and radical beliefs were assessed as were evaluations of feminists. A structural equation model was used to explore these relationships; life experiences were found to influence women's beliefs, which in turn influenced feminist self-identification, which influenced collective action. We found that life experiences may serve as a catalyst for both feminist self-identification and collective action.     

Demonstrating the Effects of Presentation Rate on Aging Memory Using the California Verbal Learning Test (CVLT)

Previous research has repeatedly found that the elderly demonstrate significant declines in direct measures of memory. This study examined verbal learning and memory in the young and old participants using the California Verbal Learning Test (CVLT). We hypothesized that slowing down the presentation rate of a list of words, therefore giving the participants more time to rehearse while learning new information, would decrease the normal differences found between the young and old adults on memory recall. However, at a faster presentation rate, the usual differences would be found. Participants took the CVLT, and correct recall responses were measured as a function of age and presentation rate. It was found, as expected, that at the faster presentation rate, the young did significantly better than the old on recall, but at the slower presentation rate, the differences between age groups diminished. It was concluded that by giving the elderly more time to rehearse information, age-related differences in memory recall could be greatly diminished.
