Apparent motion: evidence of the influence of shape, slant, and size on the correspondence process

Four stimulus elements configured as a notional diamond were flashed in pairs to elicit apparent motion. When the elements were identical (4 Zs), the direction of apparent motion was ambiguous. When the elements were pairs of different letters (Cs and Os, Es and Zs), letters of different sizes (Zs and zs), or oppositely oblique lines, the direction of apparent motion tended to be between identical elements. This was true, however, only for an initial, brief observation period. Subsequently, the direction of apparent motion tended to be determined by the direction of motion perceived at first, regardless of the character of the elements. This quickly established directional set (within 10 sec) largely swamped any tendency to resolve correspondence in terms of a feature of the stimulus. It appears to be based on spatial rather than retinal or egocentric coordinates.     

Pavlovian phenomena in conditioned acceleration—Stimulus summation

Four naive male rats were separately fear-conditioned to two stimuli (light and sound) by pairing these stimuli with shocks. During Sidman avoidance these unreinforced stimuli elicited increases in response rates (conditioned acceleration). In a multiple schedule with light-shock and sound-shock reinforcements in the first component, the rats were tested for summation effects in the second (avoidance) component by presenting the light twice, the sound twice and the compound twice. They were then extinguished by eliminating the shocks in the first component. The effects of compounding were evidenced by: (1) a sizeable and reliable amplitude increase to the compound stimulus during conditioning; (2) a smaller and less consistent decrease in latencies during conditioning in all four subjects; and (3) a greater resistance to extinction for the compound stimulus as measured by mean amplitudes for all four subjects and on six of seven extinction sessions. Latency data during extinction were inconclusive. An additional unexpected finding was what appeared to be a two-factor secondary extinction of the avoidance itself as a result of Pavlovian extinction. The responding in the first four minutes of avoidance was inhibited to such an extent that the number of shocks received during this period increased 700 per cent from the last three conditioning sessions to the first three extinction sessions.     

Prognostic signs for the pastoral counselor from the life of Christ

Summary In this paper I have suggested examples of character traits in persons Jesus tells us about, or whom he dealt with, which can serve as suggestive material in determining the prognosis of persons either in or contemplating pastoral counseling. Among these I have given: first, the ability of a person to reach out, still trying to become life-related or to maintain the relations which he has already established; second, the capacity of the person for relationship, his being able to have feeling, interest, or concern for others, or reality beyond himself; and, third, I have indicated the idea of a person's being able to look at himself in an objective sense, not merely needing to live a defensive life, guardedly protecting his ego as though it could not tolerate any kind of a critical approach. In these concepts of self I believe we have the basic questions regarding the person's success or failure in the process of pastoral counseling.     

Naming consistency in Alzheimer''s disease

Although lexical semantic deficits are postulated to play a prominent role in the anomia of Alzheimer's disease, it is unclear whether the primary disturbance is one of lexical access or one of lexical semantic loss. Response consistency on a naming task is one means of evaluating the underlying source of naming impairment. Access dysfunction usually implies variable word-finding difficulty, while a theory of lexical loss predicts that many word names would be consistently unavailable. Nineteen Alzheimer's disease patients were administered a visual confrontation naming task (the Boston Naming Test) on two occasions 6 months apart. Eighty percent of errors occurred consistently at both times; only 20% of errors occurred on only one occasion. Response consistency occurred significantly more often than expected under the assumption of no response consistency. Findings support the hypothesis that anomia in Alzheimer's disease is in part due to a loss of lexical semantic information.     

A call for a pluralist epistemological understanding in the assessment and evaluation of counselling

The authors outline and posit the futility of the 'paradigm war' between reductionistic/positivistic and phenomenological/naturalistic philosophies within counselling evaluation, pointing out that the notion of such competition is itself based on positivist thinking. They trace attempts at creating a 'truce' in the war based on strict demarcation of territory. They conclude that in the longer term more might be gained by accepting the veracity of both philosophies and creating a pluralist model which will be more fully equipped to evaluate the human process of counselling.     

Validation of the Micropat Battery

Micropat is a battery of computer-based aptitude tests designed to assess aspects of psychomotor coordination and information management. Initial research and development work on Micropat started in 1980 with the Army Air Corps and the tests were successfully validated against rotary wing pilot training outcome. In 1985, funding for the project was taken over by the Royal Navy (RN) with a view to improving selection for both RN Pilots and RN Observers. Validation of the main battery was carried out on Pilot and Observer trainees at Britannia Royal Naval College (BRNC), Dartmouth, UK. The paper outlines the development of the Micropat programme over the past decade, focusing on a number of key practical methodological issues. These include discussion of the task-based approach to test construction, the use made of the potential afforded by computer-based assessment and the problem of developing robust composite predictors from small samples. In particular, the relative merits of unit-weighted, rationally weighted and empirically weighted composite predictors are examined. Evidence for the validity of the tests is summarized. It is concluded that we are unlikely to improve substantially on the levels of prediction which were being obtained in the 1950s. Continual development and improvement in selection testing is needed simply to maintain levels of prediction as the demands of flying change. The new forms of test made possible by computer-based assessment technology provide the means of maintaining useful levels of prediction as flying training courses become longer and more complex.     

The Role of Computer-Based Test Interpretation (CBTI) in Occupational Assessment

The paper explores a range of issues relating to the design and use of computer-based test interpretation (CBTI) systems. It describes a number of dimensions along which CBTI systems vary and considers both the positive and negative implications of these for test users, for their clients and for test candidates. A distinction is drawn between systems that generate finished reports and those that generate questions or guidance for the user. The question of how the validity of narrative reports can be assessed is considered. A study on the discriminative validity of reports generated by the PREVUE ICES CBTI system is reported which shows clear differences between judgements made about true and bogus reports. It is concluded that there are two main issues to consider when evaluating a CBTI system: first, the validity of the information generated by it and, second, the ways in which that information is likely to be used.     

Accreditation Standards for University and College Counseling Centers

The accreditation standards outlined in the article are used by the International Association of Counseling Services, Inc., as the basis for the formal accreditation of college and university counseling programs throughout the United States and Canada. They reflect the program elements and practice standards that are deemed essential in a counseling center that provides high-quality services to students.     

Confirmation holism and semantic holism

Fodor and Lepore, in their recent book Holism, maintain that if an inference from semantic anatomism to semantic holism is allowed, certain fairly deleterious consequences follow. In Section 1 Fodor and Lepore's terminology is construed and amended where necessary with the result that the aforementioned deleterious consequences are neither so apparent nor straightforward as they had suggested. In Section 2 their Argument A is considered in some detail. In Section 3 their argument attributed to Quine is examined at length and a shorter and more perspicacious argument suggested which avoids their charge that the Quinean argument is guilty of an equivocation on the word statement.
