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.

Laterality Strength Is Linked To Stress Reactivity In Port Jackson Sharks (Heterodontus Portusjacksoni), Evan E. Byrnes, Catarina Vila Pouca, Culum Brown

Culum Brown, PhD

Cerebral lateralization is an evolutionarily deep-rooted trait, ubiquitous among the vertebrates and present even in some invertebrates. Despite the advantages of cerebral lateralization in enhancing cognition and facilitating greater social cohesion, large within population laterality variation exists in many animal species. It is proposed that this variation is maintained due links with inter-individual personality trait differences. Here we explored for lateralization in Port Jackson sharks (Heterodontus portusjacksoni) using T-maze turn and rotational swimming tasks. Additionally, we explored for a link between personality traits, boldness and stress reactivity, and cerebral lateralization. Sharks demonstrated large individual and sex biased laterality …

Stress Profile Influences Learning Approach In A Marine Fish, Vincent Raoult, Larissa Trompf, Jane E. Williamson, Culum Brown

Culum Brown, PhD

The spatial learning skills of high and low stress juvenile mulloway (Argyrosomus japonicus) were tested in a dichotomous choice apparatus. Groups of fish were formed based on background blood cortisol levels and required to learn the location of a food reward hidden in one of two compartments. Low stress fish characterised by low background levels of the stress hormone cortisol had higher activity levels and entered both rewarded and unrewarded rooms frequently. Within the first week of exposure, however, their preference for the rewarded room increased, indicative of learning. Fish that had high background levels of cortisol, in …

Elevated Sensitivity To Tactile Stimuli In Stereotypic Horses, Sabrina Briefer Freymond, Déborah Bardou, Sandrine Beuret, Iris Bachmann, Klaus Zuberbühler, Elodie Briefer

Elodie Briefer, PhD

Although stereotypic behaviors are a common problem in captive animals, why certain individuals are more prone to develop them remains elusive. In horses, individuals show considerable differences in how they perceive and react to external events, suggesting that this may partially account for the emergence of stereotypies in this species. In this study, we focused on crib-biting, the most common stereotypy displayed by horses. We compared how established crib-biters (“CB” = 19) and normal controls (“C” = 18) differed in response to a standard “personality” assessment test battery, i.e., reactivity to humans, tactile sensitivity, social reactivity, locomotor activity, and curiosity …

Personality Types And Learning Styles Of Collegiate Aviation Students, Stephanie Fussell, Andrew R. Dattel, Kadie Mullins

Kadie Hayward Mullins

The personality types and learning styles of students have been studied across education populations, yet the research analyzing aviation students is lacking. A replication study assessed the distribution of personality types and learning styles of students enrolled in the aeronautical science baccalaureate degree program at Embry-Riddle Aeronautical University (ERAU). The Myers-Briggs Type Indicator (MBTI) Form M and the Kolb Learning Style Inventory (KLSI) were used to analyze the personality types and learning styles, respectively. When compared to the personality type distribution of the traditional college student sample using a selection ratio type table, a significant overrepresentation of the personality type …

Personality Affects Learning And Trade-Offs Between Private And Social Information In Guppies, Poecilia Reticulate, Larissa Trompf, Culum Brown

Culum Brown, PhD

The acquisition of information such as the location and quality of food, mates or shelter is a key survival requirement for animals. Individuals can acquire information through personal experience (private information) or through observing and interacting with others (social information). Environmental spatial and temporal heterogeneity can mean that sometimes social information conflicts with private knowledge. We tested how personality affected the importance placed on public versus private information in wild female guppies when these two information sources came into conflict. We found that boldness and sociality affected decisions to use conflicting social and private information. Bolder females used social information …

Laterality Is Linked To Personality In The Black-Lined Rainbowfish, Melanotaenia Nigrans, Culum Brown, Anne-Laurence Bibost

Culum Brown, PhD

Emotions such as fear in vertebrates are often strongly lateralised, that is, a single cerebral hemisphere tends to be dominant when processing emotive stimuli. Boldness is a measure of an individual’s propensity to take risks and it has obvious connections with fear responses. Given the emotive nature of this well-studied personality trait, there is good reason to suspect that it is also likely to be expressed in a single hemisphere. Here, we examined the link between laterality and boldness in wild and captive-reared rainbowfish, Melanotaenia nigrans. We found that fish from the wild were bolder than those from captivity, which …

Cognitive Failures At Work, Mindfulness, And The Big Five, Karen Klockner, Richard Hicks

Richard Hicks

Cognitive failures at work (or errors in the workplace including blunders and memory lapses), can lead to considerable personal and organisational damage, even damage well beyond national borders in some organisations. Workplace errors may have a personality base; and mindfulness (or mindlessness) also appears to be related to workplace errors generally. Given the importance and cost of errors in the workplace it is of concern that no previous research appears to have addressed the relationships between cognitive failures at work, personality and mindfulness together. We aimed to address this gap. We administered the Cognitive Failures Questionnaire, the Mindful Attention Awareness …

Coping And Ego Depletion: Recovery After The Coping Process, Roy Baumeister, Jon Faber, Harry Wallace

Harry M. Wallace

In this chapter, we combine a new approach to the self with a traditional, standard idea about coping in order to understand the coping process. The central idea is that many operations of the self involve the consumption of a limited resource. This resource is used in volition (e.g., choice, responsible decision-making, and active responses) and self-control. Stress makes severe demands on this resource, because people must engage in active responding and must regulate themselves so as to adapt to difficult circumstances. One major consequence of stress is that the resource becomes depleted. This will impair the person's functioning across …

Trait Impulsivity Predicts D-Kefs Tower Test Performance In University Students, Michael Lyvers, Vanessa Basch, Helen Duff, Mark Edwards

Mark Edwards

The present study examined a widely used self-report index of trait impulsiveness in relation to performance on a well-known neuropsychological executive function test in 70 university undergraduate students (50 women, 20 men) aged 18 to 24 years old. Participants completed the Barratt Impulsiveness Scale (BIS-11) and the Frontal Systems Behavior Scale (FrSBe), after which they performed the Tower Test of the Delis-Kaplan Executive Function System. Hierarchical linear regression showed that after controlling for gender, current alcohol consumption, age at onset of weekly alcohol use, and FrSBe scores, BIS-11 significantly predicted Tower Test Achievement scores, b¼_.44, p

Animal Personality As A Cause And Consequence Of Contest Behaviour, Mark Briffa, Lynne U. Sneddon, Alistair J. Wilson

Lynne Sneddon, PhD

We review the evidence for a link between consistent among-individual variation in behaviour (animal personality) and the ability to win contests over limited resources. Explorative and bold behaviours often covary with contest behaviour and outcome, although there is evidence that the structure of these ‘behavioural syndromes’ can change across situations. Aggression itself is typically repeatable, but also subject to high within-individual variation as a consequence of plastic responses to previous fight outcomes and opponent traits. Common proximate mechanisms (gene expression, endocrine control and metabolic rates) may underpin variation in both contest behaviour and general personality traits. Given the theoretical links …

Introduction: Context And Background To Australian Research In Personality And Individual Differences, Richard Hicks

Richard Hicks

Extract: Interest and research in personality and individual differences, in why people behave the way they do and the implications for life and living, remain unabated around the world. Human beings are fascinated by how they are similar to one another and how they are different. The similarities and differences underpin many implicit and espoused theories of behaviour and of personal and professional practice, informing the decisions that we all make on what we will do and when.

Personality And Task Performance, Trishita Mathew, Richard Hicks

Richard Hicks

While the positive effects of goal setting and self-efficacy on performance are well established (Bandura, 1997; Locke & Latham, 1990) and it is known that task anxiety can lead to detriments in performance (Locke & Latham, 1990); it is not known which variable affects task performance the most. The present study aimed to identify the strongest predictor of task performance among self-efficacy, goal setting and task anxiety. The study was conducted with a total of 80 participants who were students from an Australian university. It was hypothesised that self-efficacy, goal setting and task anxiety would be significant predictors of task …

Recklessness In Context: Individual And Situational Correlates To Aggressive Driving, Paul B. Harris, John M. Houston

Paul Harris

Traffic-related injury and fatality are major health risks in the United States and worldwide. One contributor to road accidents is unsafe and aggressive driving practices. We examined individual and situational aspects of aggressive driving by having 152 undergraduate students complete self-report measures. Aggressive driving was related to personality variables, such as hostility, sensation seeking, and competitiveness, as well as to social variables such as driving without passengers and characteristics of the target vehicle (e.g., passengers, age, and status of driver), environmental variables (e.g., type of road, traffic, and weather), and temporal variables (e.g., time pressure and time of day).

Some Personality Predictors Of Tolerance To Human Diversity: The Roles Of Openness, Agreeableness And Empathy, Rivka Witenberg, Ninawa Butrus

Rivka T Witenberg Dr

The aim of this study was to determine the most salient predictors of tolerance to human diversity. A total of 118 individuals (M = 32.93 years, SD = 13.80) responded to dilemma-like stories involving holding prejudicial beliefs (beliefs), talking about them (speech) and acting on them (acts). Participants also completed the Openness and Agreeableness scales from the Big Five Inventory and the Interpersonal Reactivity Index. Differences in tolerance judgements were found to be related to differences in personality characteristics. Results showed that Openness and Agreeableness were predictors of tolerance in the belief dimension; whereas the most salient predictor of tolerance …

How Does Personality Develop?, Dan Mcadams, Jonathan Adler

Jonathan M. Adler

There are good reasons to be skeptical about any efforts to bring together two fields of inquiry that have historically had little to do with each other - that is, personality psychology and the study of human development. Personality psychologists are by training, and maybe even temperament, suspicious of the idea of development, for to them it means change (i.s. instability, inconsistency), and personality is nothing if it is not at least somewhat enduring. Developmentalists, on the other hand, specialize in a certain kind of change - meaningful and orderly change over time.

Defining And Measuring Self-Concept Change, Jonathan Gore, Susan Cross

Jonathan Gore

The self-concept and the manners by which it changes are two of the most important, and challenging, areas of psychological study. In this review, we define the self-concept as a multifaceted psychological construct, composed of a variety of characteristics. People with low self-esteem, incremental theorists, self-monitors, and people with a high uncertainty orientation and relational self-construal are mentioned as some of the types of people who are likely to undergo change. Various approaches to measuring the self-concept and investigating it across cultures are also discussed. Recommendations for future research include utilizing an intraclass correlation coefficient measure of change, and accounting …

The Relations Among Personality, Symptoms Of Alcohol And Marijuana Abuse, And Symptoms Of Comorbid Psychopathology: Results From A Community Sample, Kate Flory, Donald Lynam, Richard Milich, Carl Leukefeld, Richard Clayton

donald r lynam

This study examined the relation of the Five-Factor Model (FFM) of personality to symptoms of alcohol and marijuana abuse before and after controlling for symptoms of antisocial personality disorder (APD) and internalizing psychopathology. The 481 participants completed a well-validated measure of the FFM and a structured diagnostic interview at age 21 years. Hierarchical regression analyses indicated that unique constellations of personality characteristics were associated with symptoms of alcohol abuse, marijuana abuse, APD, and internalizing disorders. For example, symptoms of alcohol abuse were associated with high Extraversion and low Conscientiousness, whereas symptoms of marijuana abuse were characterized by low Extraversion and …

The Relationship Between Personality And Self-Report Abilities, Julie Schermer, Andrew Johnson, Philip Vernon, Kerry Jang

Andrew M. Johnson

The relationship between self-report abilities and personality was examined at both the phenotypic (zero-order) level as well as at the genetic and environmental levels. Twins and siblings (N = 516) completed self-report ability and personality questionnaires. A factor analysis of the ability questions revealed 10 factors, including politics, interpersonal relationships, practical tasks, intellectual pursuits, academic skills, entrepreneur/business, domestic skills, vocal abilities, and creativity. Five personality factors were examined, including extraversion, conscientiousness, dependence, aggression, and openness. At the phenotypic level, the correlations between the ability factor scores and personality factor scores ranged from 0 to .60 (between political abilities and extraversion). …

Is Creativity Domain-Specific? Latent Class Models Of Creative Accomplishments And Creative Self-Descriptions, Paul J. Silvia, James C. Kaufman, Jean E. Pretz

Jean E Pretz

Note: This article may not exactly replicate the final version published in the APA journal. It is not the copy of record. http://www.apa.org/journals/aca/ Is creativity domain-specific? The authors describe the value of latent class analysis for appraising domain generality, and the authors report two studies that explore the latent class structure of creative accomplishments (using Carson, Peterson, and Higgins’s Creative Achievement Questionnaire; n #1; 749) and creative self-descriptions (using Kaufman and Baer’s Creativity Domain Questionnaire; n #1; 3,534). For creative achievements, clear latent classes were found: the majority of people belonged to an “uncreative” class, and smaller classes were found …
