Title The running horse stops: the hypothetical role of the eyes in imagery of movement Type Journal Article
Year 1999 Publication Perceptual and motor skills Abbreviated Journal Percept Mot Skills
Volume 89 Issue 3 Pt 2 Pages 1088-1092
Keywords Adult; Cerebral Cortex/physiology; Eye Movements/*physiology; Female; Functional Laterality/physiology; Head/physiology; Humans; *Imagination; Models, Neurological; *Motion Perception; Movement/physiology; *Ocular Physiology; *Optical Illusions; Posture/physiology
Abstract To examine the hypothetical role of the eyes in visual mental imagery of movement 72 undergraduate women students in psychology were asked to imagine a running horse and then to produce the same mental image without moving the eyes and the head. In 59% of the subjects interesting modifications of the imagined movement appeared: 37% observed an inhibition of the movement and 19% an evident slowing up of the moving figure. The interpretation of this result was made by hypothesizing that the eyes are concretely involved in visual imagery processes.

Title A preliminary investigation of the construct of psychopathic personality (psychopathy) in chimpanzees (Pan troglodytes) Type Journal Article
Year 1999 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 113 Issue 4 Pages 365-375
Keywords Age Factors; Analysis of Variance; Animals; Antisocial Personality Disorder/*diagnosis/psychology; Ethology/*methods; Female; Male; Observer Variation; Pan troglodytes/*psychology; Psychiatric Status Rating Scales/*standards; Reproducibility of Results; Sex Characteristics; *Social Behavior
Abstract Although the construct of psychopathy has received considerable attention in humans, its relevance to other animals is largely unknown. We developed a measure of psychopathy for use in chimpanzees (Pan troglodytes), the Chimpanzee Psychopathy Measure (CPM), and asked 6 raters to complete this index on 34 chimpanzees. The CPM (a) demonstrated satisfactory interrater reliability and internal consistency; (b) exhibited marginally significant sex differences (males > females); (c) correlated positively with measures of extraversion, agreeableness, and observational ratings of agonism, sexual activity, daring behaviors, teasing, silent bluff displays, and temper tantrums, and negatively with observational ratings of generosity; and (d) demonstrated incremental validity above and beyond a measure of dominance. Although further validation of the CPM is needed, these findings suggest that the psychopathy construct may be relevant to chimpanzees.

Title Heart rate responses to social interactions in free-moving rhesus macaques (Macaca mulatta): a pilot study Type Journal Article
Year 1999 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 113 Issue 1 Pages 59-65
Keywords Animals; Behavior, Animal/physiology; Female; Grooming/physiology; Heart Rate/*physiology; Macaca mulatta/*physiology; Male; Movement/*physiology; Pilot Projects; *Social Behavior
Abstract Heart rate telemetry was explored as a means to access animal emotion during social interactions under naturalistic conditions. Heart rates of 2 middle-ranking adult females living in a large group of rhesus macaques (Macaca mulatta) were recorded along with their behavior. Heart rate changes during 2 types of interactions were investigated, while controlling for the effects of posture and activity. The risk of aggression associated with the approach of a dominant individual was expected to provoke anxiety in the approachee. This prediction was supported by the heart rate increase after such an approach. No increase was found when the approacher was a kin or a subordinate individual. The tension-reduction function of allogrooming was also supported. Heart rate decelerated faster during the receipt of grooming than in matched control periods.

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 Support for a theory of memory for event duration must distinguish between test-trial ambiguity and actual memory loss Type Journal Article
Year 1999 Publication Journal of the experimental analysis of behavior Abbreviated Journal J Exp Anal Behav
Volume 72 Issue 3 Pages 467-472
Keywords Animals; Behavior, Animal/physiology; Columbidae; Conditioning, Operant/physiology; Discrimination Learning/physiology; Memory/*physiology; *Psychological Theory; Time Factors; Time Perception/physiology
Abstract Staddon and Higa's (1999) trace-strength theory of timing and memory for event duration can account for pigeons' bias to “choose short” when retention intervals are introduced and to “choose long” when, following training with a fixed retention interval, retention intervals are shortened. However, it does not account for the failure of pigeons to choose short when the intertrial interval is distinct from the retention interval. That finding suggests that stimulus generalization (or ambiguity) between the intertrial interval and the retention interval may result in an effect that has been attributed to memory loss. Such artifacts must be eliminated before a theory of memory for event duration can be adequately tested.

Title Cultures in chimpanzees Type Journal Article
Year 1999 Publication Nature Abbreviated Journal Nature
Volume 399 Issue 6737 Pages 682-685
Keywords Animals; *Behavior, Animal; Cognition; *Culture; Humans; Pan troglodytes/*physiology; Species Specificity
Abstract As an increasing number of field studies of chimpanzees (Pan troglodytes) have achieved long-term status across Africa, differences in the behavioural repertoires described have become apparent that suggest there is significant cultural variation. Here we present a systematic synthesis of this information from the seven most long-term studies, which together have accumulated 151 years of chimpanzee observation. This comprehensive analysis reveals patterns of variation that are far more extensive than have previously been documented for any animal species except humans. We find that 39 different behaviour patterns, including tool usage, grooming and courtship behaviours, are customary or habitual in some communities but are absent in others where ecological explanations have been discounted. Among mammalian and avian species, cultural variation has previously been identified only for single behaviour patterns, such as the local dialects of song-birds. The extensive, multiple variations now documented for chimpanzees are thus without parallel. Moreover, the combined repertoire of these behaviour patterns in each chimpanzee community is itself highly distinctive, a phenomenon characteristic of human cultures but previously unrecognised in non-human species.
