Early Instinct Approaches • Popular in late 1800’s • Wm. James and Wm. McDougall • Lists
Behaviorists • Criticisms of Instinct Model • Nominal Fallacy • Confusion with Learning • Concept “dies” in Psychology
Ethology • Kept instinct concept “alive” • Studied animal behavior • Evolutionary adaptiveness of behavior • Naturalistic Observation • Simple Experiments • Ethograms • Lorenz and Tinbergen
Ethology Methods • Naturalistic observation • Taxonomy of behavior • Simple demonstration experiments
Ethological Terms • Appetitive Behavior • Consummatory Behavior • Action Specific Energy (ASE) • Innate Releasing Mechanism (IRM) • Key Stimulus (KS) • Fixed Action Pattern (FAP)
Key Stimuli • Sign Stimuli • Social Releaser • Categories of Key Stimuli • Simple • Complex/Configurational • Supernormal
Supernormal Key Stimuli • Cuckoo’s egg and chick • Rowland’s (1989c) Stickleback study • Receptive females • Ceramic males • Normal • 1.5 times normal • Measured preference (distance from model) • Preference for a supernormal stimulus may be advantageous (survival of offspring)
Fixed Action Patterns • Characteristics of FAPS • Stereotyped • Rigid, fixed, species-specific • Independent of Immediate External Control • Graylag goose • FAP vs TAXIS • Spontaneous • Flycatcher • Vacuum Activity • Independent of Learning • Hailman’s Gull experiment
Human Ethology • Eibl-Eibesfeldt • Research • Cross-cultural • Challenged children • Blind • Deaf • retarded
Universality of Facial Expressions • Smiling • Laughing • Weeping • Frowning • Eyebrow Flick
The Eyebrow Flick • Found in his films • 1/6 sec • Part of “greeting ceremony” • Eye contact • Smiling • Raising eyebrows • A FAP • Appeasement gesture
Eye contact in primates • Threat gesture in primates • More complex in humans • Lockhart’s field study
Facial Emotional Expression • Ekman’s group • Research • Cross-cultural • Methods • Japanese/American Study • Display Rules
Facial Feedback Hypothesis • Muscle feedback from face • Ekman, Friesen & Ancoli (1980) • FACS • Zygomatic Major muscles • Strack, Martin & Stepper, (1988) • Larsen, Kasimatis, & Frey, (1992)
Key Stimuli in Humans • Eibl-Eibesfeldt – Physical characteristics of infants • Neoteny and survival value • Human Infant Characteristics • Large head relative to body • Large eyes • Roundedness • Keating et al. (2003) – adults with neotenous faces receive more help
Recent Approaches • Behavioral Ecology – how do behavior and the environment interact? • Cognitive Ethology – information processing in animals • Evolutionary Psychology – human genetically controlled behavior
Behavioral Ecology • Studies the relationships between behaviors and the environment • E.g. Predator-prey interactions • Competition among species members for limited resources • Social interactions in groups • Aggressive behavior • Sexual behavior • Parental Care
Group Membership – Why do many animals live in groups? • Causes competition for resources; however, group membership provides an overall advantage to the individual • Increased protection from predators • Dilution effect • Increased overall vigilance by the group • Alarm signals • Finding new food sources • Following behavior
Cognitive Ethology/Animal Cognition • Studies how animals interpret information • Two main approaches • Conscious awareness not assumed • E.g. Shettleworth, (2001) • Animals have some limited consciousness • Griffin (2001)
Consciousness • Perceptual consciousness • Marking Test (Povinelli et al., 1997) • Reflective consciousness • Self-awareness?
Evolutionary Psychology • “The analysis of the human mind as a collection of evolved mechanisms,” (Buss, 1999, p.47). • Mechanisms to solve specific problems • Decision Rules • Physiological Activity • More decision processes • Behavior
Evolutionary Psychology (Cont.) • Hinsz, Matz & Patience (2001). • Correlational study • Does a woman’s hair provide clues to her reproductive potential? • Such signals common in other animals • Male lions manes and immune system • Birdsong and immune system
Hinsz et al. (2001) found: • Hair length correlated with age • Hair quality correlated with health • Barber (1995) - Male physical appearance serves to communciate: • Social dominance • Female attraction
