AN EVALUATION OF THE RELATIONSHIP BETWEEN RECEPTIVE SPEECH SKILLS AND EXPRESSIVE SIGNING

We examined the effects of receptive speech on the acquisition of manual signing among three mentally retarded children. In an alternating treatments design, we compared the acquisition of expressive signs that were, versus were not, in a child's receptive vocabulary. The children were trained via total communication in which pictorial referents were named during sign training. Signs corresponding to known words were generally acquired faster and retained better than signs corresponding to unknown words. We conducted posttests to assess the stimulus control of signing and any changes in expressive and receptive signing and speech. Observed changes in performance could be accounted for by attention to aspects of the stimulus complex during training and functional equivalence of stimuli established by training.     

Two kinds of identity crisis

In order to outline a model of identity crisis, it is necessary to distinguish two types. In an identity deficit ("motivation crisis"), the individual experiences a lack of guiding commitments but struggles to establish personal goals and values. In an identity conflict ("legitimation crisis"), the person has several commitments which prescribe conflicting behavioral imperatives in some situations, such that at least one commitment may have to be betrayed. The literature on identity crisis is reviewed in connection with this distinction, and an attempt is made to delineate the causes, the subjective experiences, behavioral consequences, and modes of resolution of each type of crisis.     

What Can 1 Million Trials Tell Us about Visual Search?

In a typical visual search experiment, observers look through a set of items for a designated target that may or may not be present. Reaction time (RT) is measured as a function of the number of items in the display (set size), and inferences about the underlying search processes are based on the slopes of the resulting RT × Set Size functions. Most search experiments involve 5 to 15 subjects performing a few hundred trials each. In this retrospective study, I examine results from 2,500 experimental sessions of a few hundred trials each (approximately 1 million total trials). These data represent a wide variety of search tasks. The resulting picture of human search behavior requires changes in our theories of visual search.     

Black-white college student attitudes and expectations in paying for dates

This study examined a black-white sample (N= 173) of university students to ascertain if there is a protocol related to paying for dates. The sample was comprised of 97 blacks and 76 whites. Most of the blacks were from a historically black university and most of the whites were from a predominantly white university, both located in the southeast. Blacks had a slightly lower mean family income when compared with whites. Both racial and gender role related attitudes and expectations related to paying for dates were also explored. African Americans have generally been noted to enact more flexible or nontraditional gender role attitudes and behaviors in some areas. This study sought to ascertain if this pattern followed in the economic dimension of dating. Findings showed race differences on several variables related to paying for dates. Blacks were found to be less flexible or more traditional than whites on several aspects of dating related attitudes and expectations. Whites were more likely to endorse more flexible role patterns and seemed less concerned with a dating protocol. Other important background variables related to more flexible gender role attitudes and expectations were classification, age, and total income of respondents' family of origin respectively.     

Selecting University Lecturers: What is and Should be Done

This paper presents a survey designed to identify the procedures used by British university departments when selecting academic staff and compare them with typical practice in other UK organizations. The results indicate that, compared with other large organizations, university departments make much less use of psychometric tests or assessment centres, relying heavily on the application form, a single interview and a presentation. There were no differences between academic departments of English, Biology or Psychology and the level of academic appointment only affected the composition of the interview panel. Possible reasons for the failure to use modern objective methods of selection are considered. It is argued that universities should apply more objective selection methods based on a full analysis of the competencies required of the higher education lecturer.     

The Primary Prevention of Illness: Social Systems and Personal Power

There is evidence to be inferred from statistics about health status and mortality rates that a large proportion of illness and premature death is preventable. Primary prevention programmes appear to have had only limited success when individuals need to take responsibility for preserving their own health. This paper examines the concept of primary prevention and its assumptions, including the need to increase the sense of personal power of individuals. It also deals with some of the problems for primary prevention policies and their implementation. Other primary prevention issues such as ethical and legal considerations. cost-benefits, foci of programmes, and the specification of goals and objectives, are considered. We propose public (government) policies to broaden the concept of health sciences for research and practice, and to give a high priority for resource allocation to prevention of illness and promotion of health, including funding of interdisciplinary research teams. We advocate taking a general systems theory approach to prevention, while enhancing and developing the sense of personal power of individual members of social systems.     

A scale of educational-vocational undecidedness: A typological approach

A scale designed to measure and identify antecedents of educational-vocational indecision was administered to a variety of college student groups expected to differ in career-decidedness. Results indicate that the scale is reliable, appears to discriminate career-decided from career-undecided students, and is responsive to interventions designed to alleviate educational-vocational indecision. A factor analysis of the scale yielded four factors: need for structure, perceived external barriers, positive choice conflict, and personal conflict. The instrument has potential for diagnostic, criterion, and conceptual purposes related to career indecision.     

Instrumental learning in preschool children as a function of type of task, type of reward, and some organismic variables

The effects on instrumental behavior of differences in type of task, type of reward and three organismic variables were investigated in preschool children. The main results were that: (a) an imitative task was acquired in fewer trials than a nonimitative task; (b) social reward in acquisition led to greater resistance to extinction; (c) a history of frequent social reinforcement from peers led to persistence in responding during extinction for boys only; (d) extraversion was found to interact with the variables of task and reward in errors made during extinction; and (e) intelligence was not found to be a reliable predictor of main acquisition and extinction measures or related errors. Detailed analysis of the different types of errors contributed directly to the interpretation of these findings.
