Deepening Our Understanding Of Sheep, Lori Marino, Debra Merskin
Deepening Our Understanding Of Sheep, Lori Marino, Debra Merskin
Lori Marino, PhD
Our Response is centered on five major themes: (1) our presentation of human mythologies about sheep; (2) the relevance of cognitive complexity (“intelligence”) as a dimension underlying the way people perceive and treat sheep; (3) whether our review is too anthropocentric or anthropomorphic; (4) animal welfare versus animal rights (abolitionism); and (5) whether knowledge and education are enough to change human attitudes and behavior.
Intelligence, Complexity, And Individuality In Sheep, Lori Marino, Debra Merskin
Intelligence, Complexity, And Individuality In Sheep, Lori Marino, Debra Merskin
Lori Marino, PhD
Domestic sheep (Ovis aries) are among the earliest animals domesticated for human use. They are consumed worldwide as mutton, hogget, and lamb, kept as wool and milk producers, and used extensively in scientific research. The popular stereotype is that sheep are docile, passive, unintelligent, and timid, but a review of the research on their behavior, affect, cognition, and personality reveals that they are complex, individualistic, and social.
Orca Behavior And Subsequent Aggression Associated With Oceanarium Confinement, Robert Anderson, Robyn Waayers, Andrew Knight
Orca Behavior And Subsequent Aggression Associated With Oceanarium Confinement, Robert Anderson, Robyn Waayers, Andrew Knight
Andrew Knight, PhD
Based on neuroanatomical indices such as brain size and encephalization quotient, orcas are among the most intelligent animals on Earth. They display a range of complex behaviors indicative of social intelligence, but these are difficult to study in the open ocean where protective laws may apply, or in captivity, where access is constrained for commercial and safety reasons. From 1979 to 1980, however, we were able to interact with juvenile orcas in an unstructured way at San Diego’s SeaWorld facility. We observed in the animals what appeared to be pranks, tests of trust, limited use of tactical deception, emotional self-control, …
Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. Mcelligott
Individual Personality Differences In Goats Predict Their Performance In Visual Learning And Non-Associative Cognitive Tasks, Christian Nawroth, Pamela M. Prentice, Alan G. Mcelligott
Alan G. McElligott, PhD
Variation in common personality traits, such as boldness or exploration, is often associated with risk–reward trade–offs and behavioural flexibility. To date, only a few studies have examined the effects of consistent behavioural traits on both learning and cognition. We investigated whether certain personality traits (‘exploration’ and ‘sociability’) of individuals were related to cognitive performance, learning flexibility and learning style in a social ungulate species, the goat (Capra hircus). We also investigated whether a preference for feature cues rather than impaired learning abilities can explain performance variation in a visual discrimination task. We found that personality scores were consistent …
Score One For Jazz: Working Memory In Jazz And Classical Musicians, Bryan E. Nichols, Clemens Wöllner, Andrea R. Halpern
Score One For Jazz: Working Memory In Jazz And Classical Musicians, Bryan E. Nichols, Clemens Wöllner, Andrea R. Halpern
Andrea Halpern
Jazz musicians rely on different skills than do classical musicians for successful performances. We investigated the working memory span of classical and jazz student musicians on musical and nonmusical working memory tasks. College-aged musicians completed the Bucknell Auditory Imagery Scale, followed by verbal working memory tests and musical working memory tests that included visual and auditory presentation modes and written or played recall. Participants were asked to recall the last word (or pitch) from each task after a distraction task, by writing, speaking, or playing the pitch on the piano. Jazz musicians recalled more pitches that were presented in auditory …
Introduction To Special Issue: Dementia And Music, Andrea R. Halpern, Isabelle Peretz, Lola L. Cuddy
Introduction To Special Issue: Dementia And Music, Andrea R. Halpern, Isabelle Peretz, Lola L. Cuddy
Andrea Halpern
This special issue follows two previous special issues on music and neurological disorders (April 2008, Volume 23/Issue 4 and April 2010, Volume 25/Issue 4). Like its predecessors, the issue presents studies employing a patient-based approach to music perception, cognition, and emotion. Whereas the earlier issues dealt with acquired and congenital disorders and impairments, the present issue focuses on dementia, primarily on its most common form, Alzheimer's disease (AD).

Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott
Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott
Alan G. McElligott, PhD
Animal emotional states can be investigated by evaluating their impact on cognitive processes. In this study, we used a judgement bias paradigm to determine if shortterm positive human-animal interaction (grooming) induced a positive affective state in goats. We tested two groups of goats and trained them to discriminate between a rewarded and a non-rewarded location over nine training days. During training, the experimental group (nD9) was gently groomed by brushing their heads and backs for five min over 11 days (nine training days, plus two testing days, total time 55 min). During training, the control group (nD10) did not experience …

Animal Welfare And Individual Characteristics: A Conversation Against Speciesism, Marc Bekoff, Lori Gruen
Animal Welfare And Individual Characteristics: A Conversation Against Speciesism, Marc Bekoff, Lori Gruen
Marc Bekoff, PhD
It seems impossible for a human being not to have some point of view concerning nonhuman animal (hereafter animal) welfare. Many people make decisions about how humans are permitted to treat animals using speciesist criteria, basing their decisions on an individual's species membership rather than on that animal's individual characteristics. Although speciesism provides a convenient way for making difficult decisions about who should be used in different types of research, we argue that such decisions should rely on an analysis of individual characteristics and should not be based merely on species membership. We do not argue that the concept of …
Constructive And Deconstructive Tool Modification By Chimpanzees (Pan Troglodytes), Amanda E. Bania, Stephany Harris, Hannah R. Kinsley, Sarah T. Boysen
Constructive And Deconstructive Tool Modification By Chimpanzees (Pan Troglodytes), Amanda E. Bania, Stephany Harris, Hannah R. Kinsley, Sarah T. Boysen
Sarah Boysen, PhD
Nine chimpanzees (Pan troglodytes) were tested for their ability to assemble or disassemble the appropriate tool to obtain a food reward from two different apparatus. In its deconstructed form, the tool functioned as a probe for one apparatus. In its constructed form, the tool functioned as a hook, appropriate for a second apparatus. Each subject completed four test trials with each apparatus type. Tool types were randomized and counter-balanced between the two forms. Results demonstrated that adult and juvenile chimpanzees (N = 7) were successful with both tool types, while two infant chimpanzees performed near chance. Off-line video analyses revealed …
Laterality Influences Cognitive Performance In Rainbowfish Melanotaenia Duboulayi, Anne-Laurence Bibost, Culum Brown
Laterality Influences Cognitive Performance In Rainbowfish Melanotaenia Duboulayi, Anne-Laurence Bibost, Culum Brown
Culum Brown, PhD
Cerebral lateralization has been suggested to convey a selective advantage to individuals by enhancing their cognitive abilities. Few, however, have explicitly compared the cognitive ability of animals with strongly contrasting laterality. Here, we examined the influence of laterality on learning performance in the crimson spotted rainbowfish, Melanotaenia duboulayi, using a classical conditioning paradigm. We also compared the learning ability of wild caught and captive-reared fish to examine the influence of rearing environment on cognitive performance. Laterality was established by observing which eye fish preferred to use while viewing their mirror image. Subjects were then conditioned to associate the appearance of …
Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews
Pantomime In Great Apes: Evidence And Implications, Ann E. Russon, Kristin Andrews
Kristin Andrews, PhD
We recently demonstrated, by mining observational data, that forest-living orangutans can communicate using gestures that qualify as Pantomime. Pantomimes, like other iconic gestures, physically resemble their referents. More elaborately, pantomimes involve enacting their referents. Holding thumb and finger together at the lips and blowing between them to mean balloon is one example. Here we sketch evidence of pantomime in other great apes, methodological concerns, and sophisticated cognitive capabilities that great ape pantomimes suggest.
Cognition In Emotional Disorders: An Abundance Of Habit And A Dearth Of Control, Paula T. Hertel
Cognition In Emotional Disorders: An Abundance Of Habit And A Dearth Of Control, Paula T. Hertel
Paula T Hertel
Emotional and other psychological disorders are categories of experience identified at least in part by the goal of having treatment plans for people in distress. Because the categories exist for such purposes, research efforts are organized to discover distinctions among the categories and between disordered and nondisordered individuals. Many of these distinctions are cognitive. When clinical scientists began experimental studies, the term “cognitive” had been used to refer primarily to conscious thoughts that characterize disorders (see Beck, 1976), but in more recent decades the term signifies an experimental approach framed according to the theories and paradigms of cognitive psychology. In …

Physical Activity And Brain Function In Older Adults At Increased Risk For Alzheimer’S Disease, J. Carson Smith, Kristy A. Nielson, John L. Woodard, Michael Seidenberg, Stephen M. Rao
Kristy Nielson
Leisure-time physical activity (PA) and exercise training are known to help maintain cognitive function in healthy older adults. However, relatively little is known about the effects of PA on cognitive function or brain function in those at increased risk for Alzheimer’s disease through the presence of the apolipoproteinE epsilon4 (APOE-ε4) allele, diagnosis of mild cognitive impairment (MCI), or the presence of metabolic disease. Here, we examine the question of whether PA and exercise interventions may differentially impact cognitive trajectory, clinical outcomes, and brain structure and function among individuals at the greatest risk for AD. The literature suggests that the protective …

Cognitive Bias Modification: Past Perspectives, Current Findings, And Future Applications, Paula T. Hertel, Andrew Mathews
Paula T Hertel
Research conducted within the general paradigm of Cognitive Bias Modification (CBM) reveals that emotional biases in attention, interpretation, and memory are not merely associated with emotional disorders but contribute to them. After briefly describing research on both emotional biases and their modification, we examine similarities between CBM paradigms and older experimental paradigms used in research on learning and memory. We also compare the techniques and goals of CBM research to other approaches to understanding cognition/emotion interactions. From a functional perspective, the CBM tradition reminds us to use experimental tools to evaluate assumptions about clinical phenomena and more generally, about causal …
Ambivalence And The Decision Tree, Kirby Farrell
Ambivalence And The Decision Tree, Kirby Farrell
kirby farrell
We are insolubly ambivalent creatures. Traditionally cultures have managed ambivalence by focusing on character and morality in motives. Freudian psychology recognized that cognitive conflict is insoluble and stressed equilibrium and grace in adaptation. Today technology's binary structure is complicating and sometimes superseding the traditional trope of character by organizing cognition around the trope of the decision tree.
Multicultural Experience Enhances Creativity: The When And How, Angela K. Y. Leung, William W. Maddux, Adam D. Galinsky, Chi-Yue Chiu
Multicultural Experience Enhances Creativity: The When And How, Angela K. Y. Leung, William W. Maddux, Adam D. Galinsky, Chi-Yue Chiu
Ka Yee Angela LEUNG
Many practices aimed at cultivating multicultural competence in educational and organizational settings (e.g., exchange programs, diversity education in college, diversity management at work) assume that multicultural experience fosters creativity. In line with this assumption, the research reported in this article is the first to empirically demonstrate that exposure to multiple cultures in and of itself can enhance creativity. Overall, the authors found that extensiveness of multicultural experiences was positively related to both creative performance (insight learning, remote association, and idea generation) and creativity-supporting cognitive processes (retrieval of unconventional knowledge, recruitment of ideas from unfamiliar cultures for creative idea expansion). Furthermore, …
Speeded Retrieval Abolishes The False Memory Suppression Effect: Evidence For The Distinctiveness Heuristic, C. S. Dodson, Amanda C. Gingerich
Speeded Retrieval Abolishes The False Memory Suppression Effect: Evidence For The Distinctiveness Heuristic, C. S. Dodson, Amanda C. Gingerich
Amanda C. Gingerich
We examined two different accounts of why studying distinctive information reduces false memories within the DRM paradigm. The impoverished relational encoding account predicts that less memorial information, such as overall famililarity, is elicited by the critical lure after distinctive encoding than after non-distinctive encoding. By contrast, the distinctiveness heuristic predicts that participants use a deliberate retrieval strategy to withhold responding to the critical lures. This retrieval strategy refers to a decision rule whereby the absence of memory for expected distinctive information is taken as evidence for an event’s nonoccurrence. We show that the typical false recognition suppression effect only occurs …
Why Distinctive Information Reduces False Memories: Evidence For Both Impoverished Relational-Encoding And Distinctiveness Heuristic Accounts, Amanda C. Gingerich, C. S. Dodson
Why Distinctive Information Reduces False Memories: Evidence For Both Impoverished Relational-Encoding And Distinctiveness Heuristic Accounts, Amanda C. Gingerich, C. S. Dodson
Amanda C. Gingerich
Two accounts explain why studying pictures reduces false memories within the Deese-Roediger-McDermott paradigm (J. Deese, 1959; H. L. Roediger & K. B. McDermott, 1995). The impoverished relational-encoding account suggests that studying pictures interferes with the encoding of relational information, which is the primary basis for false memories in this paradigm. Alternatively, the distinctiveness heuristic assumes that critical lures are actively withheld by the use of a retrieval strategy. When participants were given inclusion recall instructions to report studied items as well as related items, they still reported critical lures less often after picture encoding than they did after word encoding. …
Rat Pup Social Motivation: A Critical Component Of Early Psychological Development, Howard C. Cromwell
Rat Pup Social Motivation: A Critical Component Of Early Psychological Development, Howard C. Cromwell
Howard Casey Cromwell
Examining the role of the offspring in early social dynamics is especially difficult. Human developmental psychology has found infant behavior to be a vital part of the early environmental setting. In the rodent model, the different ways that a rodent neonate or pup can influence social dynamics are not well known. Typically, litters of neonates or pups offer complex social interactions dominated by behavior seemingly initiated and maintained by the primary caregiver (e.g., the dam). Despite this strong role for the caregiver, the young most likely influence the litter dynamics in many powerful ways including communication signals, discrimination abilities and …

Abstract. Perinatal exposure to PCB has been reported to cause a variety of health effects including endocrine disruption, and immunologic, reproductive, neurologic, and behavioral deficits. In the present study, a mixture of two PCB congeners, one non-coplanar (PCB 47) and one coplanar (PCB 77), were administered to young female Sprague-Dawley rats by route of maternal dietary consumption (either 12.5 ppm or 25.0 ppm, w/w). Impact on learning and memory were examined by radial arm maze on postnatal day 24-27. After behavioral tests were completed, the rats were transcardially perfused, and brains were excised. Immunohistochemistry for ER- β was carried out …
