Redundancy in the perception of bilateral symmetry in dot textures

Redundancy in the perception of bilateral symmetry in dynamic dot textures was investigated using two-alternative forced-choice techniques. It was found that the symmetry information utilized by the visual system fell within a strip approximately 1 deg wide about the central axis of symmetry, irrespective of the size of the texture at the retina. Outside this strip, the symmetry information was found to be completely redundant.     

Matching the rate of concurrent tone bursts and light flashes as a function of flash surround luminance

Subjects adjusted the rate of a repeating toneburst to match that of a concurrently flashing light, or vice versa. Flashes were viewed in luminous or wholly dark surrounds. Matches usually departed from veridical rate matches, and always were affected in the same direction by changes in surround luminance. Matches were a function of whether subjects controlled the visual or auditory stimulus; also, subjects usually reported “driving” of flash rates by auditory rates when they controlled tone rate, but not when they controlled flash rate.     

Career-learning space: New-dots thinking for careers education

For more than 20 years, both careers education and guidance have drawn much of their rationale from the DOTS analysis which analyses practice for coverage of decision learning (D), opportunity awareness (O), transition learning (T), and self awareness (S). Its assumptions are rooted in theory, unifying the aims of careers education and careers guidance as enabling choice. More recent theory and practice engage a wider range of thinking: they acknowledge the complexity of contemporary career planning, and accommodate interactions which occur in the social and community life of the 'choosing person'. The practical implications are for more progressive career learning, in conditions which enable 'due process' to establish viable bases for both choice and change of mind. This thinking more sharply differentiates careers education from guidance, setting out a strong rationale for the former. It does not replace DOTS, but extends it into a new-DOTS re-conceptualisation termed 'career-learning space'. The effectiveness of career learning is determined by its transferable outcomes. New-DOTS thinking resonates with the conditions for transferable learning. There are possibilities here for building a strong consensus between practice, theory and policy.     

Use of delayed feedback and reinforcement for reducing inappropriate behaviors with chronically institutionalized mental clients

This study investigated the efficacy of: (a) delayed feedback; (b) delayed feedback and social reinforcement; or (c) delayed feedback, social reinforcement, and tangible reinforcement for reducing the rate of bizarre motoric behaviors for 2 female and 1 male chronically institutionalized mental clients. These treatments were consecutively employed with each subject, utilizing a multiple baseline across subjects experimental design. Results indicated that these subjects were able to retain and understand the feedback on both their problem and alternative behaviors but that reductions in the inappropriate motoric behaviors resulted only when tangible reinforcers were included in the treatment. Implications for further investigations and for the utility and efficiency of delayed feedback and reinforcement with chronically institutionalized adults are discussed.     

Feature encoding and pattern classifications with sequentially presented Markov stimuli

The major objective of this experiment was to develop and evaluate a methodology designed to permit more direct assessment of the detailed processes involved in prototype abstraction. Thirty Ss participated in a task having the following characteristics: (1) classifications of Markov-generated stimuli sampled from two different populations, (2) controlled scanning of pattern features, (3) a measure of the degree to which pattern features were correctly identified, and (4) intermittent reproduction of pattern features abstracted from collections of mixed instances. Results showed that a significant number of the Ss learned to classify the stimuli into categories corresponding to generation rules and, at least partially, abstracted the population prototypes from these variable instances. The feature identification data suggested that the Ss who were unsuccessful in classifying the stimuli into the rule-defined categories used an inappropriate strategy for sampling pattern information upon which to base their classifications.     

Factors affecting grief adjustment

Earlier research has suggested that therapy and time are factors of change in grief level for those who are grieving. This follow-up study of widows and widowers suggests that there are also other relevant factors such as church activities, death of other relatives, other activities, time of grief counseling group, health, age, consideration of remarriage, religion, number of months widowed, and financial situation. A regression analysis of 138 widows and widowers found each of these factors significantly related to the. 05 critical level of significance to various measures of grief level.     

The contexts of system orientation in secondary-school counselling

This is the fourth and final article in a series exploring the ways in which secondary-school counsellors resolve their working dilemmas. It examines evidence to suggest that the resolution of such dilemmas, in terms of the degree to which the demands of the school are legitimated, is carried out in the internal context of other considerations in the minds of the counsellors. Among these other considerations are the extent to which they seek to work within a 'person-focussed' frame of reference, as opposed — perhaps — to the use of organisational structures; and the extent to which they see themselves in a posture of active 'interventionism' in the lives of their clients or the functioning of the system. Evidence is also examined which indicates that the effects of system orientation may be modified by the external context, represented by the capacity of the system as an organismic cell to resist ingression. The suggestion emerges that counsellors are involved in sociological as well as psychological tasks, requiring an ecology model to represent them adequately.     

The role of physiological attention-focusing in the relaxation treatment of sleep disturbance,general tension,and specific stress reaction

Three experiments comparing the effects of muscle tension-release relaxation with vs without physiological attention-focusing and no-treatment on (a) sleep disturbance, (b) general tension, and (c) a variety of time estimation, heart rate perception, and stress reaction measures, are reported. The two relaxation conditions produced equivalent reductions in latency to sleep onset reports, suggesting the importance of tension-release in the relaxation treatment of sleep disturbance. Relaxation without physiological attention-focusing was unexpectedly superior to the other relaxation condition in reducing reported daily tension, supporting Denny's (1976) hypothesis that pervasive anxiety may be a function of anxiety conditioned to relaxation-produced cues. Sleep disturbed subjects over-estimated elapsed time, and relaxation training improved accuracy of time estimation. Several additional differences between sleep and tension subjects and among the three treatment conditions on physiological activity during stress are reported and discussed.     

Counsellors as teachers

An examination of the arguments for and against the role combination of teaching and counselling leads to a view of counselling as being, in some senses, an ingression into the traditional practices of teaching and, in other senses, an egression from them. The traditional practices of teaching are, therefore, analysed in such a way as to generate items for an inventory to measure 'teacher identification'. The inventory also includes items which invite respondents to reject the ingression of non-teaching principles and practices. En route to the development of the inventory, some observations are made concerning the kinds of role combination with teaching which counsellors tend most to resist.
