Measurement Of Color Preference In Goldfish Using A Negative Reinforcement Y-Maze Avoidance Procedure, Dominic Zerbolio Jan 1980

Measurement Of Color Preference In Goldfish Using A Negative Reinforcement Y-Maze Avoidance Procedure, Dominic Zerbolio

UMSL Emeritus

Using a Y-maze procedure involving shock reinforcement, goldfish were forced to choose between a red or a green cued arm of the maze. Although the 18 animals tested showed, as a group, an average green preference, equal numbers of animals showed individual green (6), red (6), and no-color (6) preferences. Differences between conclusions based on group means against individual performances are noted. In goldfish, at least, the shock-reinforced Y-maze procedure may represent a very useful technique for further color preference assessment.

Instrumentally Based Conditioned Avoidance Response Acquisition In Goldfish In A Simultaneous Presentation Task, Dominic Zerbolio, L L. Wickstra Apr 1979

Instrumentally Based Conditioned Avoidance Response Acquisition In Goldfish In A Simultaneous Presentation Task, Dominic Zerbolio, L L. Wickstra

UMSL Emeritus

Goldfish, run in a Y-maze, with the simultaneous presentation of a cue associated with shock and a second cue associated with safety (no US), acquired a decided preference for the safe cue. These data are interpreted as representing a clear demonstration of stimulus-specific conditioned avoidance. Because earlier research has been challenged by unusual control performances, this instrumental learning conclusion is hesitantly drawn.

Passive Avoidance In Goldfish: Lack Of Evidence For Stimulus Specificity, Dominic Zerbolio, L L. Wickstra Jun 1978

Passive Avoidance In Goldfish: Lack Of Evidence For Stimulus Specificity, Dominic Zerbolio, L L. Wickstra

UMSL Emeritus

Goldfish, acquiring a passive avoidance response, showed substantially fewer responses in trial intervals than did their yoked controls. A passive procedure, where US reinforcement occurred immediately upon response, produced superior avoidance acquisition to a punishment procedure, where, if response occurred at any time during the trial interval, US reinforcement was administered at the end of the interval. This finding is consistent with the traditional delay of reinforcement gradient. Although goldfish acquired the passive avoidance response, it appeared to be situationally generalized and not stimulus specific, as indicated by a lack of differences between animals trained with a CS and those …

Goldfish Avoidance Acquisition: Is The Process Classical, Instrumental, Or A Phototaxis?, Dominic Zerbolio, L L. Wickstra Apr 1978

Goldfish Avoidance Acquisition: Is The Process Classical, Instrumental, Or A Phototaxis?, Dominic Zerbolio, L L. Wickstra

UMSL Emeritus

Various active-avoidance procedures and controls were run using goldfish in a shuttlebox where the CS, when used, was a sudden onset of illumination. In terms of increasing “avoid- ance” performance over days of training, CS-only, response-contingent US-only, and time- lapse groups showed significant “learning,” whereas explicitly unpaired CS and US pseudo- conditioning controls and US only (where US omission is not response contingent) did not show performance increases. The use of the pseudoconditioning procedure as a learning control for this animal seems questionable. Additionally, both classically and instrumentally trained groups showed high and comparable acquisition rates, confirming earlier findings. A …

Does Elimination Of A Negative Phototaxis Eliminate Car Acquisition In Goldfish?, Dominic Zerbolio, L L. Wickstra Apr 1978

Does Elimination Of A Negative Phototaxis Eliminate Car Acquisition In Goldfish?, Dominic Zerbolio, L L. Wickstra

UMSL Emeritus

Eleven groups run under classical, instrumental, pseudoconditioning, CS-only, US-only, and time-lapse procedures, with the ITI illuminated and a color change CS, showed that true classically trained animals do not increase CAR performance with training, whereas instru- mentally trained goldfish do. This is consistent with a phototaxic interpretation suggested in earlier work. Additionally, the finding that CS-only and time-lapse controls show high “acquisi- tion” rates, whereas pseudoconditioning controls do not, not only questions the use of the pseudoconditioning procedure as the sole learning control in this situation, but also questions a learning interpretation itself. Conclusions of what and how, or even …

"A Rose Is A Rose Is A Rose": The Definition Debate, Norman Powell Dec 1976

"A Rose Is A Rose Is A Rose": The Definition Debate, Norman Powell

Norman W. Powell

There has been much discussion and debate among child care workers about the definition of "child care workers." Who is a child care worker? What does the child care worker do with children that is unique and different from the teacher, nurse, the social worker, or the psychologist does?

Spatially Located Visual Cs Effects In Conditioned Shuttlebox Avoidance In Goldfish: A Phototactic Explanation, Dominic Zerbolio Oct 1976

Spatially Located Visual Cs Effects In Conditioned Shuttlebox Avoidance In Goldfish: A Phototactic Explanation, Dominic Zerbolio

UMSL Emeritus

Earlier work found that goldfish (Carassius auratus) acquire a conditioned avoidance shuttle response (CASR) differentially as a function of CS location (same, opposite, or both tank ends) when the CS is a sudden onset of illumination, and hypothesized that subjects acquire an aversion to the light. The present study finds no evidence for a conditioned aversion, but shows initial negative phototactic effects in the onset illumination situation which occurs without acquisition. Additionally, when the localized CS is a color change rather than an illumination change, the differential effects between same and both do not occur, and the very low CASR …

Weak Type Multipliers For Hankel Transforms, William C. Connett, Alan L. Schwartz Feb 1976

Weak Type Multipliers For Hankel Transforms, William C. Connett, Alan L. Schwartz

UMSL Emeritus

The main result of this paper is that weak type multiplier theorems for Jacobi expansions yield weak type multiplier theorems for Hankel transforms.

In recent papers the authors studied multiplier theorems for ultraspherical and Jacobi expansions. An interesting paper of Igari suggested a new approach to multiplier theorems that used asymptotics instead of the elaborate machinery used earlier.

This paper extends the method of Igari to give the first weak type multiplier theorem for Hankel transforms. This extension is important in itself and because this method together with the authors’ results for Jacobi multipliers will generalize to the “radial” functions …

Contemporary Historical Research Conference, John A. Henschke Edd Mar 1974

Contemporary Historical Research Conference, John A. Henschke Edd

John A. Henschke

The problems and rewards of conducting contemporary historical research are related in the light of the author's experiences in preparing an Ed.D. dissertation analyzing Malcolm, S. Knowles' contributions to and influence on the field of adult study accurate but inconclusive. The major portion of the dissertation was based on data available in documents by or about Knowles, but an "opinionnaire" schedule (an adaptation of the Applied Behavioral Science Interview schedule), loosely constructed and open-ended, was sent to 150 former colleagues and students of Knowles. The problems raised by this form of research are discussed by the author. Three areas of …

Malcolm S. Knowles: His Contributions To The Theory And Practice Of Adult Education, John A. Henschke Edd

John A. Henschke

The central question of this study was: What are the contributions in theory and practice Malcolm S. Knowles has made to the emerging field of adult education? The nature of the study as contemporary history of a living person's educational work, required the findings to be preliminary. The source of information used to answer the central question were: interviews with and questionnaire responses of contemporaries of Knowles and Malcolm S. Knowles who served as "prime information resource;" writing so Knowles and others; and documents and proceedings of a variety of organizations influenced by Knowles. Sections were included on the influence …
