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, …

Lateralized Difference In Tympanic Membrane Temperature: Emotion And Hemispheric Activity, Ruth E. Propper, Tad T. Brunyé

Ruth Propper

We review literature examining relationships between tympanic membrane temperature (TMT), affective/motivational orientation, and hemispheric activity. Lateralized differences in TMT might enable real-time monitoring of hemispheric activity in real-world conditions, and could serve as a corroborating marker of mental illnesses associated with specific affective dysregulation. We support the proposal that TMT holds potential for broadly indexing lateralized brain physiology during tasks demanding the processing and representation of emotional and/or motivational states, and for predicting trait-related affective/motivational orientations. The precise nature of the relationship between TMT and brain physiology, however, remains elusive. Indeed the limited extant research has sampled different participant populations …

Asymmetry In Resting Alpha Activity: Effects Of Handedness, Ruth E. Propper, Jenna Pierce, Mark W. Geisler, Stephen D. Christman, Nathan Bellorado

Ruth Propper

Frontal electroencephalographic (EEG) alpha band power during rest shows increased right, and/or decreased left, hemisphere activity under conditions of state or trait withdrawal-associated effect. Non-right-handers (NRH) are more likely to have mental illnesses and dispositions that involve such withdrawal-related effect. The aim of the study was to examine whether NRH might be characterized by increased right, relative to left, hemisphere activity during rest. Methods: The present research investigated that hypothesis by examining resting EEG alpha power in consistently-right-handed (CRH) and NRH individuals. Results: In support of the hypothesis, NRH demonstrated decreased right hemisphere alpha power, and therefore increased right hemisphere …

Perception Of Structure In Novel Music, Andrea R. Halpern

Andrea Halpern

Two experiments demonstrated the way in which musicians and nonmusicians process realistic music encountered for the first time. A set of tunes whose members were related to each other by a number of specific musical relationships was constructed. In experiment I, subjects gave similarity judgments of all pairs of tunes, which were analyzed by the ADD-TREE clustering program. Musicians and nonmusicians gave essentially equivalent results: Tunes with different rhythms were rated as being very dissimilar, whereas tunes identical except for being in a major versus a minor mode were rated as being highly similar. In Experiment 2, subjects learned to …

Dynamic Aspects Of Musical Imagery, Andrea Halpern

Andrea Halpern

Auditory imagery can represent many aspects of music, such as the starting pitches of a tune or the instrument that typically plays it. In this paper, I concentrate on more dynamic, or time-sensitive aspects of musical imagery, as demonstrated in two recently published studies. The first was a behavioral study that examined the ability to make emotional judgments about both heard and imagined music in real time. The second was a neuroimaging study on the neural correlates of anticipating an upcoming tune, after hearing a cue tune. That study found activation of several sequence-learning brain areas, some of which varied …

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).

The Effects Of Diegetic And Nondiegetic Music On Viewers’ Interpretations Of A Film Scene, Elizabeth M. Wakefield, Siu-Lan Tan, Matthew P. Spackman

Elizabeth Wakefield

Previous studies have shown that pairing a film excerpt with different musical soundtracks can change the audience’s interpretation of the scene. This study examined the effects of mixing the same piece of music at different levels of loudness in a film soundtrack to suggest diegetic music (“source music,” presented as if arising from within the fictional world of the film characters) or to suggest nondiegetic music (a “dramatic score” accompanying the scene but not originating from within the fictional world). Adjusting the level of loudness significantly altered viewers’ perceptions of many elements that are fundamental to the storyline, including inferences …

Bringing Emotions Into Social Exchange Theory, Edward J. Lawler, Shane R. Thye

Edward J Lawler

We analyze and review how research on emotion and emotional phenomena can elaborate and improve contemporary social exchange theory. After identifying six approaches from the psychology and sociology of emotion, we illustrate how these ideas bear on the context, process, and outcome of exchange in networks and groups. The paper reviews the current state of the field, develops testable hypotheses for empirical study, and provides specific suggestions for developing links between theories of emotion and theories of exchange.

The Theory Of Relational Cohesion: Review Of A Research Program, Shane R. Thye, Jeongkoo Yoon, Edward J. Lawler

Edward J Lawler

In this paper we analyze and review the theory of relational cohesion and attendant program of research. Since the early 1990s, the theory has evolved to answer a number of basic questions regarding cohesion and commitment in social exchange relations. Drawing from the sociology of emotion and modem theories of social identity, the theory asserts that joint activity in the form of frequent exchange unleashes positive emotions and perceptions of relational cohesion. In turn, relational cohesion is predicted to be the primary cause of commitment behavior in a range of situations. Here we outline the theory of relational cohesion, tracing …

A Conceptual Affective Design Framework For The Use Of Emotions In Computer Game Design, Penny De Byl

Penny de Byl

The purpose of this strategy of inquiry is to understand how emotions influence gameplay and to review contemporary techniques to design for them in the aim of devising a model that brings current disparate parts of the game design process together. Emotions sit at the heart of a game player’s level of engagement. They are evoked across many of the components that facilitate gameplay including the interface, the player’s avatar, non-player characters and narrative. Understanding the role of emotion in creating truly immersive and believable environments is critical for game designers. After discussing a taxonomy of emotion, this paper will …

Relative Reward Effects On Operant Behavior: Incentive Contrast,Induction And Variety Effects, Howard Cromwell

Howard Casey Cromwell

Comparing different rewards automatically produces dynamic relative outcome effects on behavior. Eachnew outcome exposure is to an updated version evaluated relative to alternatives. Relative reward effectsinclude incentive contrast, positive induction and variety effects. The present study utilized a novelbehavioral design to examine relative reward effects on a chain of operant behavior using auditory cues.Incentive contrast is the most often examined effect and focuses on increases or decreases in behavioralperformance after value upshifts (positive) or downshifts (negative) relative to another outcome. Weexamined the impact of comparing two reward outcomes in a repeated measures design with three ses-sions: a single outcome and …

A Detailed Investigation Of Facial Expression Processing In Congenital Prosopagnosia As Compared To Acquired Prosopagnosia, Kate Humphreys, Galia Avidan, Marlene Behrmann

Marlene Behrmann

Whether the ability to recognize facial expression can be preserved in the absence of the recognition of facial identity remains controversial. The current study reports the results of a detailed investigation of facial expression recognition in three congenital prosopagnosic (CP) participants, in comparison with two patients with acquired prosopagnosia (AP) and a large group of 30 neurologically normal participants, including individually age- and gender-matched controls. Participants completed a fine-grained expression recognition paradigm requiring a six-alternative forced-choice response to continua of morphs of six different basic facial expressions (e.g. happiness and surprise). Accuracy, sensitivity and reaction times were measured. The performance …

A Fine-Grained Analysis Of Facial Expression Processing In High-Functioning Adults With Autism, Kate Humphreys, Nancy Minshew, Grace Leonard, Marlene Behrmann

Marlene Behrmann

It is unclear whether individuals with autism are impaired at recognizing basic facial expressions, and whether, if any impairment exists, it applies to expression processing in general, or to certain expressions, in particular. To evaluate these alternatives, we adopted a fine-grained analysis of facial expression processing in autism. Specifically, we used the ‘facial expression megamix’ paradigm [Young, A. W., Rowland, D., Calder, A. J, Etcoff, N. L., Seth, A., & Perrett, D. I. (1997). Facial expression megamix: Tests of dimensional and category accounts of emotion recognition Cognition and Emotion, 14, 39–60] in which adults with autism and a typically …

Animal Cognition, Kristin Andrews, Ljiljana Radenovic

Kristin Andrews, PhD

Debates in applied ethics about the proper treatment of animals often refer to empirical data about animal cognition, emotion, and behavior. In addition, there is increasing interest in the question of whether any nonhuman animal could be something like a moral agent.

Effects Of Polychlorinated Biphenyl (Pcb) On Response Perseveration And Ultrasonic Vocalization Emission In Rat During Development, Howard Cromwell

Howard Casey Cromwell

The 3 major symptoms of autistic spectrum disorders include 1) social behavioral alterations, 2) problems in communication and 3) higher-order motoric deficits of perseveration and stereotyped movements. Previous work has shown that early developmental exposure to polychlorinated biphenyls (PCBs) alters rat pup social motivation and juvenile rat social recognition/investigation. The present work extends this previous research by examining how perinatal PCB exposure alters motoric functions and communication abilities at different stages of development. Action perseveration was examined using performance measures from a T-maze environment. Communication abilities were evaluated by monitoring ultrasound emission in rat pups during a brief isolation from …

With Feeling: How Emotions Shape Negotiation, Mara Olekalns, Daniel Druckman

Mara Olekalns

An increasingly popular topic in current research is how emotional expressions influence the course of negotiation and related interactions. Negotiation is a form of social exchange that pits the opposing motives of cooperating and competing against one another. Most negotiators seek to reach an agreement with the other party; they also strive for an agreement that serves their own goals. This dual concern is reflected in a process that consists of both bargaining and problem solving. A good deal of the research and practice literature concentrates on ways to perform these activities effectively. In earlier writing, emotions were viewed largely …

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 …

The Diverse Neurogeography Of Emotional Experience: Form Follows Function, Christoper Sharpley, Vicki Bitsika

Vicki Bitsika

The experience of emotion underlies emotional expression and consequent action. Although several theoretical models of emotion have suggested that emotional expression is reciprocally involved with sensory inputs and behavioural responses to environmental stimuli, these discussions have largely focused upon fear and its survival value to the organism. By describing research studies across a wide range of emotions and the specific brain regions that are associated with those emotions, this review raises the hypothesis that the “form” of emotional experience neurogeography has followed the “function” associated with developing complex emotional and behavioural responses to challenging environmental stimuli. This separation of emotions …

An Increase In Stimulus Arousal Has Differential Effects On The Processing Speed Of Pleasant And Unpleasant Stimuli, Helena Purkis, Ottmar Lipp, Mark Edwards, Rebecca Barnes

Mark Edwards

The arousal value of a stimulus influences its salience, whereby higher arousal should lead to faster processing. However, in previous research, participants consistently made faster valence judgments for low arousal, pleasant stimuli than for high arousal, pleasant stimuli. The speed of valence and arousal judgments for pictures and words were investigated in three experiments. Valence judgments were faster for low arousal than for high arousal pleasant pictures and for high arousal than for low arousal unpleasant pictures and words. Moreover, arousal judgments were faster for low arousal than high arousal pleasant and for high arousal than low arousal unpleasant pictures …

Rats Selectively Bred For Low Levels Of 50 Khz Ultrasonic Vocalizations Exhibit Alterations In Early Social Motivation, Howard C. Cromwell

Howard Casey Cromwell

In rats, the rates of 50 kHz ultrasonic vocalizations (USVs) can be used as a selective breeding phenotype and variations in this phenotype can be an indicator of affective states. The 50 kHz USV is elicited by rewarding stimuli (e.g., food, sexual behavior) and therefore can express a positive affective state. Conversely, the 22 kHz USV is elicited by aversive stimuli (e.g., presence of a predator, social defeat) indicating a negative affective state. In the present study, we tested the effect of selectively breeding for 50 kHz USVs on a variety of maternal social/emotional behaviors in young rat pups (PND …

Using Fmri To Investigate A Component Process Of Reflection: Prefrontal Correlates Of Refreshing A Just-Activated Representation, Marcia K. Johnson, Carol L. Raye, Karen J. Mitchell, Erich J. Greene, William A. Cunningham, Charles A. Sanislow

Charles A. Sanislow, Ph.D.

Using fMRI, we investigated the functional organization of prefrontal cortex (PFC) as participants briefly thought of a single just-experienced item (i.e., refreshed an active representation). The results of six studies, and a meta-analysis including previous studies, identified regions in left dorsolateral, anterior, and ventrolateral PFC associated in varying degrees with refreshing different types of information (visual and auditory words, drawings, patterns, people, places, or locations). In addition, activity increased in anterior cingulate with selection demands and in orbitofrontal cortex when a nonselected item was emotionally salient, consistent with a role for these areas in cognitive control (e.g., overcoming "mental rubbernecking"). …
