Title Configural/holistic processing or differential element versus compound similarity Type Journal Article
Year 2005 Publication Animal cognition Abbreviated Journal Anim. Cogn.
Volume 8 Issue 2 Pages 141-142
Keywords Animals; *Chickens; Conditioning, Classical; *Discrimination Learning; Female; *Pattern Recognition, Visual; Photic Stimulation; *Visual Perception
Abstract Before accepting a configural or holistic account of visual perception, one should be sure that an analytic (elemental) account does not provide an equal or better explanation of the results. I suggest that when one forms a compound of a color and a line orientation with one element previously trained as an S+ and the other as an S-, the resulting transfer found will depend on the relative salience of the two elements, and most important, the similarity of the compound to each of the training stimuli. Thus, if a line orientation is placed on a colored background (a separable compound), it will appear more like the colored field used in training, and color will control responding. However, if the line itself is colored (an integral compound), the compound will appear more like the line used in training, and line orientation will control responding. Not only does this account do a better job of explaining the data but it is simpler and it is testable.

Title Evidence for detection of one duration sample and default responding to other duration samples by pigeons may result from an artifact of retention-test ambiguity Type Journal Article
Year 2004 Publication Journal of experimental psychology. Animal behavior processes Abbreviated Journal J Exp Psychol Anim Behav Process
Volume 30 Issue 2 Pages 129-134
Keywords Animals; Artifacts; Association Learning; Columbidae; *Discrimination Learning; *Recognition (Psychology); *Retention (Psychology); *Time Perception; *Transfer (Psychology)
Abstract S. C. Gaitan and J. T. Wixted (2000) proposed that when pigeons are trained on a conditional discrimination to associate 1 duration sample with 1 comparison and 2 other duration samples with a 2nd comparison, they detect only the single duration, and on trials involving either of the 2 other duration samples, they respond to the other comparison by default. In 2 experiments, the authors show instead that pigeons lend to treat the retention intervals (such as those used by Gaitan and Wixted) as intertrial intervals, and thus, they tend to treat all trials with a delay as 0-s sample trials. The authors tested this hypothesis by showing that divergent retention functions do not appear when the retention interval is discriminably different from the intertrial interval.

Title Choice based on exclusion in pigeons Type Journal Article
Year 2003 Publication Psychonomic bulletin & review Abbreviated Journal Psychon Bull Rev
Volume 10 Issue 4 Pages 959-964
Keywords Animals; Appetitive Behavior; *Association Learning; *Choice Behavior; *Color Perception; Columbidae; *Discrimination Learning; Memory, Short-Term; *Problem Solving; Psychomotor Performance; Reaction Time; Transfer (Psychology)
Abstract When humans acquire a conditional discrimination and are given a novel-sample-comparison choice, they often reject a comparison known to be associated with a different sample and choose the alternative comparison by default (or by exclusion). In Experiment 1, we found that if, following matching training, we replaced both of the samples, acquisition took five times longer than if we replaced only one of the samples. Apparently, the opportunity to reject one of the comparisons facilitated the association of the other sample with the remaining comparison. In Experiment 2, we first trained pigeons to treat two samples differently (to associate Sample A with Comparison 1 and Sample B with Comparison 2) and then trained them to associate one of those samples with a new comparison (e.g., Sample A with Comparison 3) and to associate a novel sample (Sample C) with a different, new comparison (Comparison 4). When Sample B then replaced Sample C, the pigeons showed a significant tendency to choose Comparison 4 over Comparison 3. Thus, when given the opportunity, pigeons will choose by exclusion.

Title Symmetry training in pigeons can produce functional equivalences Type Journal Article
Year 2003 Publication Psychonomic bulletin & review Abbreviated Journal Psychon Bull Rev
Volume 10 Issue 2 Pages 387-391
Keywords Animals; Association; Behavior, Animal; Columbidae; Conditioning (Psychology)/*physiology; Teaching/*methods; *Transfer (Psychology)
Abstract Functional stimulus equivalence has been demonstrated using a transfer of training design with matching-to-sample training in which two sample stimuli are associated with the same comparison stimulus (A-B, C-B; many-to-one matching). Equivalence is shown by training a new association (A-D) and demonstrating the presence of an emergent relation (C-D). In the present experiment, we show that symmetry training, in which a bidirectional association is trained between two stimuli (A-B, B-A, using successive stimulus presentations followed by reinforcement), can also produce functional equivalence using a transfer of training design (i.e., train B-C, test A-C). The results suggest that training pigeons in the substitutability of two stimuli may be sufficient to produce functional stimulus equivalence between them. The results also have implications for the development of an emergent transitive relation, because training on A-B and B-C relations results in the emergence of an untrained A-C relation, if B-A training also is provided.

Title Categorization, concept learning, and behavior analysis: an introduction Type Journal Article
Year 2002 Publication Journal of the experimental analysis of behavior Abbreviated Journal J Exp Anal Behav
Volume 78 Issue 3 Pages 237-248
Keywords Animals; Association Learning; *Concept Formation; *Discrimination Learning; Humans; Language
Abstract Categorization and concept learning encompass some of the most important aspects of behavior, but historically they have not been central topics in the experimental analysis of behavior. To introduce this special issue of the Journal of the Experimental Analysis of Behavior (JEAB), we define key terms; distinguish between the study of concepts and the study of concept learning; describe three types of concept learning characterized by the stimulus classes they yield; and briefly identify several other themes (e.g., quantitative modeling and ties to language) that appear in the literature. As the special issue demonstrates, a surprising amount and diversity of work is being conducted that either represents a behavior-analytic perspective or can inform or constructively challenge this perspective.

Title Transfer of value from S+ to S- in simultaneous discriminations in humans Type Journal Article
Year 1999 Publication The American journal of psychology Abbreviated Journal Am J Psychol
Volume 112 Issue 1 Pages 21-39
Keywords Adolescent; Adult; Animals; Color Perception; Columbidae; Conditioning, Classical; *Discrimination Learning; Female; Humans; Male; Middle Aged; *Motivation; Orientation; Pattern Recognition, Visual; Psychomotor Performance; Reaction Time; *Transfer (Psychology)
Abstract When animals learn a simultaneous discrimination, some of the value of the positive stimulus (S+) appears to transfer to the negative stimulus (S-). The present experiments demonstrate that such value transfer can also be found in humans. In Experiment 1 humans were trained on 2 simple simultaneous discriminations, the first between a highly positive stimulus, A (1,000 points); and a negative stimulus, B (0 points); and the second between a less positive stimulus, C (100 points); and a negative stimulus, D (0 points). On test trials, most participants preferred B over D. In Experiments 2 and 3 the value of the 2 original discriminations was equated in training (A[100]B[0] and C[100]D[0]). In Experiment 2 the values of the positive stimuli were then altered (A[1,000]C[0]); again, most participants preferred B over D. In Experiment 3, however, when the values of B and D were altered (B[1,000]D[0]), participants were indifferent to A and C. Thus, the mechanism that underlies value transfer in humans appears to be related to Pavlovian second-order conditioning. Similar mechanisms may be involved in assimilation processes in social contexts.

Title Value transfer in a simultaneous discrimination appears to result from within-event pavlovian conditioning Type Journal Article
Year 1996 Publication Journal of experimental psychology. Animal behavior processes Abbreviated Journal J Exp Psychol Anim Behav Process
Volume 22 Issue 1 Pages 68-75
Keywords Animals; Behavior, Animal; Columbidae; *Conditioning, Classical; *Discrimination Learning; Female; Male; *Reinforcement (Psychology)
Abstract When pigeons acquire a simple simultaneous discrimination, some of the value acquired by the S+ transfers to the S-. The mechanism underlying this transfer of value was examined in three experiments. In Experiment 1, pigeons trained on two simultaneous discriminations (A + B- and C +/- D-) showed a preference for B over D. This preference was reduced, however, following the devaluation of A. In Experiment 2, when after the same original training, value was given to D, the pigeons' preference for C did not significantly increase. In Experiment 3, when both discriminations involved partial reinforcement (S +/-), A + C- training resulted in a preference for B over D, whereas B + D- training resulted in a preference for A over C. Thus, simultaneous discrimination training appears to result in bidirectional within-event conditioning involving the S+ and S-.

Title Control of pigeons' matching-to-sample performance by differential sample response requirements Type Journal Article
Year 1983 Publication The American journal of psychology Abbreviated Journal Am J Psychol
Volume 96 Issue 1 Pages 37-49
Keywords Animals; Association; *Color Perception; Columbidae; Cues; *Discrimination Learning; Reinforcement Schedule; Time Factors
Abstract Pigeons were trained on a matching-to-sample task in which sample hue and required sample-specific observing behavior provided redundant, relevant cues for correct choices. On trials that involved red and yellow hues as comparison stimuli, a fixed-ratio 16 schedule (FR 16) was required to illuminate the comparisons when the sample was red, and a differential-reinforcement-of-low-rates 3-sec schedule (DRL 3-sec) was required when the sample was yellow. On trials involving blue and green hues as comparison stimuli, an FR 16 schedule was required when the sample was blue and a DRL 3-sec schedule was required when the sample was green. For some pigeons, a 0-sec delay intervened between sample offset and comparison onset, whereas other pigeons experienced a random mixture of 0-sec and 2-sec delay trials. Test trial performance at 0-sec delay indicated that sample-specific behavior controlled choice performance considerably more than sample hue did. Test performance was independent of whether original training involved all 0-sec delay trials or a mixture of 0-sec and 2-sec delays. Sample-specific observing response requirements appear to facilitate pigeons' matching-to-sample performance by strengthening associations between the observing response and correct choice.

Title Word learning in dogs? Type Journal Article
Year 2004 Publication Trends in Cognitive Sciences Abbreviated Journal Trends. Cognit. Sci.
Volume 8 Issue 11 Pages 479-81; discussion 481
Keywords Animals; Association Learning; Dogs; *Learning; *Verbal Learning; *Vocabulary
Abstract In a recent paper, Kaminski, Call and Fischer report pioneering research on word-learning in a dog. In this commentary we suggest ways of distinguishing referential word use from mere association. We question whether the dog is reasoning by exclusion and, if so, compare three explanations – learned heuristics, default assumptions, and pragmatic reasoning – as they apply to children and might apply to dogs. Kaminski et al.'s work clearly raises important questions about the origins and basis of word learning and social cognition.

Title A method for assessing the relative sociability of individuals within groups: an example with grazing sheep Type Journal Article
Year 2005 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 91 Issue 1-2 Pages 57-73
Keywords Association; Grazing; Nearest neighbour; Sheep; Sociability; Social behaviour
Abstract We describe a method for quantifying relative sociability within a group of animals, which is defined as the tendency to be close to others within the group and based on the identification of nearest neighbours. The method is suitable for groups of animals in which all individuals are visible and identifiable and has application as a tool in other areas of behavioural research. A sociability index (SI) is calculated, which is equivalent to the relative proportion of time that an individual spends as the nearest neighbour of other animals in the group and is scaled to have an expectation of 1.0 under the null hypothesis of random mixing. Associated pairs, which are animals seen as nearest neighbours more often than would be expected by chance, are also identified. The method tests for consistency across a number of independent observation periods, by comparison with values obtained from simulations in which animal identities are randomised between observation periods. An experiment is described in which 8 groups of 7 grazing sheep were each observed for a total of 10, one-hour periods and the identities and distances away of the 3 nearest neighbours of each focal animal recorded at 5-min intervals. Significant within-group differences in SIs were found in four of the groups (P < 0.001). SIs calculated using the nearest neighbour, two nearest neighbours or three nearest neighbours, were generally highly correlated within all groups, with little change in the ranking of animals. There were significant negative correlations between SIs and nearest neighbour distances in five of the groups. It was concluded that there was no advantage in recording more than one neighbour to calculate the SI. Advantages of the SI over other methods for measuring sociability and pair-wise associations are discussed.
