Tactile conditioning of an autonomic and somatic response in young infants

Tactile classical conditioning of an autonomic reflex (pupillary dilation and constriction) and a somatic response (eyeblinking) was attempted in two separate experiments with one-month-old infants. The tactile CS was effective for conditioning eyeblinking but was ineffective for elaborating conditional pupillary reflex dilation or constriction. These differences were related to the interaction between stimulus and response in infant conditioning and the source of nervous system innervation of the CR as it relates to conditionability.     

The effect of a pre-shock signal on a free-operant avoidance response

After 25 free-operant avoidance training sessions, a 1-min signal followed by a brief shock was presented on the average of once every 4 min. During the signal, the avoidance schedule was suspended (20 sessions). Response rates during the signal were markedly reduced. Shock rates during non-signalled periods increased. Fifteen additional sessions were given during which the signal was presented without shock. Response rates during signalled periods were greater than previously observed during signalled periods, indicating that signalled shock had suppressive control over a previously acquired avoidance response rate.     

Short-term memory for simultaneously presented visual and auditory signals in the pigeon

A series of divided-attention experiments in which matching to the visual or auditory component of a tone-light compound was compared with matching to visual or auditory elements as sample stimuli were carried out. In 0-s delayed and simultaneous matching procedures, pigeons were able to match visual signals equally well when presented alone or with a tone; tones were matched at a substantially lower level of accuracy when presented with light signals than when presented as elements. In further experiments, it was demonstrated that the interfering effect of a signal light on tone matching was not related to the signaling value of the light, and that the prior presentation of light proactively interfered with auditory delayed matching. These findings indicate a divided attention process in which auditory processing is strongly inhibited in the presence of visual signals.     

Conditions for a Justifiable Careers Education

It is argued that an earlier analysis of careers education and guidance (R.J. Roberts, 1980) provided a justification for careers education at the level of theory, but that for this theory to give rise to practical consequences that can be similarly justified, several conditions have to be met. Six conditions relating to the operation of schools are discussed, and a number of further lines for consideration are identified.     

What makes a task difficult?

Summary This study explores the relationship between different task requirements and children's task performance and ratings of task difficulty. Four hundred and sixty five children (9 to 13 years old) read texts and answered questions, involving well-defined or ill-defined goals and requiring different thought operations. It was found that rated difficulty and performance were highly related for questions involving a well-defined goal. A simple modus ponens inference was easiest, checking most difficult, and recall of the text ranked in the middle. A question, involving an ill-defined goal was rated to be most difficult, whereas performance was quite high. The results confirm the assumptions that judgment of difficulty relies on two sources of information: 1) perception of goal, and 2) perception of processing effort.     

The effect of time-out release contingencies on changes in child noncompliance

This project evaluated the effect of time-out release contingencies on changes in child noncompliance to maternal instructions. Twenty-four clinic-referred, noncompliant, preschool children served as subjects. Each child was assessed under baseline conditions and then under one of three experimental conditions: Parent Release, Child Release, or Control. Children in the Parent Release and Child Release conditions experienced time-out contingent upon noncompliance. Temporal and behavioral time-out release contingencies were present in the Parent Release condition but not in the Child Release condition. A spanking procedure was used to inhibit premature escape from time-out for children in the Parent Release group. The results indicated that both time-out groups demonstrated increased compliance ratios. However, improvement associated with the Child Release condition was considered to be clinically insignificant.The authors wish to express their appreciation to Dave DeLawyer, Larry Snapp, and Mike Samac for their assistance in conducting the study.     

Dimensions of Problem Behavior in institutionalized retardates

A factor analysis of teacher ratings of 55 items of deviant behavior in a sample of 252 institutionalized retardates resulted in the emergence of three interpretable factors. Two factors clearly represented the broad-band dimensions of conduct disorder and anxiety-withdrawal, while the third reflected psychotic behavior. Only conduct disorder was related to age, sex, trace, or intellectual level.     

A multitrait-multimethod analysis of variance of teachers' ratings of aggression,hyperactivity, and inattention

The convergent and discriminant validities of three teacher rating scale measures of the traits of hyperactivity, aggression, and inattention were explored, using the multitrait-multimethod matrix approach of Campbell and Fiske (1959), as well as an analysis of variance procedure (Stanley, 1961). In the present study teachers rated children from their elementary school classrooms on the above traits. The results provided strong evidence for convergent validity. Data also indicated that these traits can be reliably differentiated by teachers, suggesting that research aimed at better understanding the unique contributions of hyperactivity, aggression, and inattention is warranted. The respective benefits of analyzing multitrait-multimethod matrices by employing the ANOVAprocedure or by using the Campbell and Fiske (1959) criteria were discussed.     

Attitudes towards single women

Empirical studies of attitudes towards, and the sociopsychological characteristics of single women have been neglected by social scientists. As a minority group, subject to normative judgements of their sex-role behavior, single women are vulnerable to prejudicial evaluations by married people of both sexes. The present study investigated aspects of the social environment which have positive or negative consequences for single women. A survey was conducted of N=48 male and female married subjects in an Australian city. Major findings were that (a) married people have little or no contact with single women; (b) males tend to be more negative in their evaluations of single women than females; and (c) most females can allow for the possibility of a major sex role other than that involving marriage.
