Community mental health services for black and ethnic minorities

An investigation into the provision of community mental health services in one local authority Borough found that facilities for the rehabilitation and resettlement of the recovering mentally ill into the community were very limited and fell far short of ofJicial recommendations and that very little consideration was given to meeting the needs of black and ethnic minorities. An analysis of data porn service providers (Local Authority/Social Services/Health Authority), multidisciplinary teams, voluntary agencies and 120 black and ethnic minorities (users and non-users of mental health services) in the Borough suggested that black and ethnic minorities had little or no say in decisions about the provision of community mental health services to the extent that they feLt excluded. In many instances service providers had limited contact with black and ethnic minorities and some members of the multidisciplinary team had little to do with black people but yet influenced major decisions about the provision of services to meet their needs. The findings drew sharp attention to the diference between the views of service providers and those of service users in terms of the provision of community mental health services to meet the needs of black and ethnic minorities. Ninety six percent of those involved in the study were appalled over the apparent lack of emphasis placed on the provision of services to meet the needs of black and ethnic minorities and felt that nothing was being done to improve the inadequate service which was offered ly the voluntary sector.     

Permanence and change in memory II. Reproduction of words in sentences

Abstract.— A retroactive interference paradigm was employed for studying qualitative memory changes. Sentences, containing an ambiguous word that was defined differently by succeeding words, were used as stimulus material. Such retroactive definitions of meaning were found to lead to qualitative changes in reproduction. It is suggested that the issue of permanence and change in memory may be related to the choice of lists of independent items or contextual units as stimulus material. A contextual theory of memory, implying the conception of memory in a stream, is advocated.     

How Discrimination Impacts Sociopolitical Behavior: A Multidimensional Perspective

The conventional wisdom regarding the impact of discrimination on political behavior is that the perception of prejudiced treatment motivates individuals to take political action. This study challenges this common conception by demonstrating that the source of discrimination can play a significant role in whether perceived or experienced injustice leads to activism or withdrawal from sociopolitical life. Drawing from political science and social psychology literature, this study provides a new perspective on the potential effects of discrimination on a relatively new marginalized group in the United States. Specifically, an important distinction is drawn between political (systematic) and societal (interpersonal) discrimination in analyzing the sociopolitical behavior of American Muslims in the aftermath of the 9/11 terrorist attacks. The results will hopefully encourage scholars to take a deeper look at the nexus between discrimination and democratic engagement, which is an important, complex, multidimensional, and understudied topic.     

Operant discrimination of relative frequency ratios in black-capped chickadee song

The two-note fee bee song of the black-capped chickadee (Poecile atricapillus) is sung at many different absolute frequencies, but the relative frequencies, or “pitch ratios”, between the start and end of the fee note (glissando) and the fee and the bee notes (inter-note interval) are preserved with each pitch-shift. Ability to perceive these ratios and their relative salience varies with sex of the bird and setting: while both sexes appear to perceive changes in the inter-note interval, males appear to attend to the glissando in the field, and females appear to attend to both ratios. In this study, we compared directly whether male and female chickadees could discriminate between normal fee bee songs and songs that had one or both of the pitch ratios altered, and whether birds attended to one type of alteration over another. Both sexes learned to discriminate normal from altered songs; songs lacking an inter-note interval were more easily discriminated than songs with only the glissando removed. Females performed slightly better than males, including in the most difficult task with the stimuli lacking the glissando. Our study illustrates the value of using perceptual tasks to directly compare performance between the sexes and to demonstrate the difference between perception of and attention to acoustic features of vocal communication.     

Smooth pursuit eye movements in normal and dyslexic children

This paper describes a detailed study of horizontal eye movements associated with visual tracking of a smoothly moving target. Essentially all children, even at target velocities as low as 5 degrees/sec., show some saccadic eye movements superimposed on smooth tracking movements. Detailed analysis of pursuit eye-movements from a group of 26 poor readers and 34 normal controls (8 to 13 yr.) showed that about 25% of poor readers have an abnormally raised saccadic component in smooth pursuit. This suggests that studies of eye movements during tracking of smoothly moving targets at low velocity, combined with a quantitative approach to data analysis, may be useful for early detection of a significant proportion of poor-reading children.     

Mother-infant responsiveness: timing, mutual regulation, and interactional context

Mutual regulation during the naturalistic interaction of 150 mothers and their 4-month-old infants was investigated from a dynamic systems perspective. Microanalyses of a wide range of behaviors and analysis of contingencies indicated that a 3-s time period best captured contingencies. Both mothers and infants communicated primarily through vocal signals and responses, although maternal touches and infant looks also elicited responses. Although more expressive mothers did not have infants who behaved similarly, levels of contingent responsiveness between partners were significantly associated and occurred within distinct behavioral channels, suggesting coregulated interactional processes in which contingently responsive mothers shape their infants' communications toward mutual similarity. Mothers were more influential than infants over object play, whereas infants were more influential than mothers over expressive behavior. Interactional context consistently influenced contingent responsiveness; there was less mutual responsiveness when the infant was exploring, being held, or looking.     

Dyslexia: saccadic eye movements

This paper describes an extensive study of the parameters of saccadic eye movement in a group of 28 poor-reading children and a comparative normally reading group of 31 children. Ages ranged from 6.0 to 16.9 yr. Poor readers had normal intelligence but were lagging by at least two years in reading ability as compared to their peer age group. Parameters studied in refixation eye movements included saccadic latency, accuracy, velocity, and acceleration, as well as differences in latency for abduct and adduct movements. Shapes of saccades were also studied. It was shown that eye-movement performance in simple saccadic refixation was not distinguishably different for poor readers and normal readers, even though in reading, which requires higher processing, eye-movement characteristics are quite different. Maturational changes for various saccadic eye-movement parameters were also examined for the normal and poor reading groups.     

Mothers' speech to their 1-year-old infants in home and laboratory settings

The speech of mothers and their 1-year-old infants was compared in the home and in the laboratory playroom. The home and laboratory settings were similar for measuring the number of actual words that infants spoke and were similar for measuring the complexity of the mother's speech, including the number of different words, the type-token ratio, and the length of the utterances. Infants vocalized at similar rates in the two settings, but mothers spoke at a faster rate in the laboratory playroom. The usefulness of a preliminary warm-up period was supported by the finding that for the second half of the sessions, mothers slowed their rate of speech and increased the complexity of their speech.
