Title | Long-term retention of the differential values of Arabic numerals by chimpanzees (Pan troglodytes) | Type | Journal Article | ||

Abstract | As previously reported (Beran and Rumbaugh, 2001), two chimpanzees used a joystick to collect dots, one-at-a-time, on a computer monitor, and then ended a trial when the number of dots collected was equal to the Arabic numeral presented for the trial. Here, the chimpanzees were presented with the task again after an interval of 6 months and then again after an additional interval of 3.25 years. During each interval, the chimpanzees were not presented with the task, and this allowed an assessment of the extent to which both animals retained the values of each Arabic numeral. Despite lower performance at each retention interval compared to the original study, both chimpanzees performed above chance levels in collecting a quantity of dots equal to the target numeral, one chimpanzee for the numerals 1-7, and the second chimpanzee for the numerals 1-6. For the 3.25-year retention, errors were more dispersed around each target numeral than in the original study, but the chimpanzees' performances again appeared to be based on a continuous representation of magnitude rather than a discrete representation of number. These data provide an experimental demonstration of long-term retention of the differential values of Arabic numerals by chimpanzees. | ||||

Title | Functional ear (a)symmetry in brainstem neural activity relevant to encoding of voice pitch: A precursor for hemispheric specialization? | Type | Journal Article | ||
Year | Publication | Brain and Language | Abbreviated Journal | ||

Abstract | Pitch processing is lateralized to the right hemisphere; linguistic pitch is further mediated by left cortical areas. This experiment investigates whether ear asymmetries vary in brainstem representation of pitch depending on linguistic status. Brainstem frequency-following responses (FFRs) were elicited by monaural stimulation of the left and right ear of 15 native speakers of Mandarin Chinese using two synthetic speech stimuli that differ in linguistic status of tone. One represented a native lexical tone (Tone 2: T2); the other, T2', a nonnative variant in which the pitch contour was a mirror image of T2 with the same starting and ending frequencies. Two 40-ms portions of f0 contours were selected in order to compare two regions (R1, early; R2 late) differing in pitch acceleration rate and perceptual saliency. In R2, linguistic status effects revealed that T2 exhibited a larger degree of FFR rightward ear asymmetry as reflected in f0 amplitude relative to T2'. Relative to midline (ear asymmetry = 0), the only ear asymmetry reaching significance was that favoring left ear stimulation elicited by T2'. By left- and right-ear stimulation separately, FFRs elicited by T2 were larger than T2' in the right ear only. Within T2', FFRs elicited by the earlier region were larger than the later in both ears. Within T2, no significant differences in FFRS were observed between regions in either ear. Collectively, these findings support the idea that origins of cortical processing preferences for perceptually-salient portions of pitch are rooted in early, preattentive stages of processing in the brainstem. | ||||

Title | Evolutionary origins of human handedness: evaluating contrasting hypotheses | Type | Journal Article | ||
Year | 2013 | Publication | Abbreviated Journal | Animal Cognition | |
Volume | 16 | Issue | 4 | Pages | 531-542 |
Keywords | Hand preference; Hemispheric specialization; Communicative gestures; Evolution of language; Nonhuman primates; Human children | ||||
Abstract | Variation in methods and measures, resulting in past dispute over the existence of population handedness in nonhuman great apes, has impeded progress into the origins of human right-handedness and how it relates to the human hallmark of language. Pooling evidence from behavioral studies, neuroimaging and neuroanatomy, we evaluate data on manual and cerebral laterality in humans and other apes engaged in a range of manipulative tasks and in gestural communication. A simplistic human/animal partition is no longer tenable, and we review four (nonexclusive) possible drivers for the origin of population-level right-handedness: skilled manipulative activity, as in tool use; communicative gestures; organizational complexity of action, in particular hierarchical structure; and the role of intentionality in goal-directed action. Fully testing these hypotheses will require developmental and evolutionary evidence as well as modern neuroimaging data. | ||||

Title | Observational word learning in two bonobos (Pan paniscus): ostensive and non-ostensive contexts | Type | Journal Article | ||
Year | 2000 | Publication | Language & Communication | Abbreviated Journal | |
Volume | 20 | Issue | 3 | Pages | 255-273 |
Keywords | Language acquisition; Bonobo; Fast mapping | ||||
Abstract | Word learning has been extensively studied in humans. Children seem to be able to map new words onto objects with only one exposure to the referent. This ability has been called “fast mapping”(Carey, 1978 and Carey). Using a modified human paradigm, this paper explores two language-competent bonobos' (Pan paniscus) abilities to map new words to objects in realistic surroundings with few exposures to the referents. This paper also investigates the necessity of the apes maintaining visual contact (ostensive context) with the item to map the novel name onto the novel object. The bonobos tested in this experiment were able to map new words onto objects and could do so without visual contact with the items. | ||||

Title | The Man Who Listens To Behavior: Folk Wisdom And Behavior Analysis From A Real Horse Whisperer | Type | Journal Article | ||
Year | 1999 | Publication | JOURNAL OF THE EXPERIMENTAL ANALYSIS OF BEHAVIOR | Abbreviated Journal | J Exp Anal Behav |
Volume | 72 | Issue | 1 | Pages | 139-149 |
Keywords | positive reinforcement, aversive control, learned helplessness, language, biological constraints, | ||||
Abstract | The popular novel and movie The Horse Whisperer are based on the work of several real-life horse whisperers, the most famous of whom is Monty Roberts. Over the last 50 years, Roberts has developed a technique for training horses that is both more effective and less aversive than traditional training techniques. An analysis of Roberts` methods (as described in his book, The Man Who Listens to Horses) indicates a deep understanding of behavioral principles including positive reinforcement, timeout, species-specific defense reactions, learned helplessness, and the behavioral analysis of language. Roberts developed his theory and techniques on the basis of personal experience and folk wisdom, and not as the result of formal training in behavior analysis. Behavior analysts can clearly learn from such insightful yet behaviorally incorrect practitioners, just as such practitioners can benefit from the objective science of behavior analysts. |
