Sentience In Fishes: More On The Evidence, Michael L. Woodruff Jan 2018

Sentience In Fishes: More On The Evidence, Michael L. Woodruff

Animal Sentience

In my target article, I argued that the brains of ray-finned fishes of the teleost subclass (Actinopterygii) are sufficiently complex to support sentience — that these fishes have subjective awareness of interoceptive and exteroceptive sense experience. Extending previous theories centered on the tectum, I focused on the organization of the fish pallium. In this Response to the commentaries, I clarify that I do not propose that the fish pallium is, or must be, homologous to the mammalian neocortex to play a role in sentience. Some form of a functionalist approach to explaining the neural basis of sentience across taxa is …


Sign Modulation By Chimpanzees To Produce Interrogatives, Kailie Dombrausky Jan 2018

Sign Modulation By Chimpanzees To Produce Interrogatives, Kailie Dombrausky

All Master's Theses

Native signers of American Sign Language produce interrogatives by holding signs for an extended duration while employing the questioning look. The questioning look is defined as raised eyebrows, a tilted head, and direct eye contact maintained for the duration of the utterance. Chimpanzees who communicate using signs have demonstrated modulation of signs including held sign, raised brow, and eye gaze. The present study used archived video data to compare the duration of signs when the chimpanzees did or did not employ the questioning look. In both single and multi-sign utterances, the chimpanzees held their signs for a mean of 0.6 …


Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews Jan 2018

Is Pecking Aversive To A Pigeon Or Is It Only The Delay To Reinforcement?, Danielle M. Andrews

Theses and Dissertations--Psychology

The principle of least effort suggests that animals should minimize effort to reinforcement. Thus, not pecking should be preferred over pecking. However, pigeons often peck when it is allowed but not required (e.g., fixed time schedules) but pecking may be adventitiously reinforced. In the present experiment, to better compare a schedule of reinforcement that requires pecking with one that requires the absence of pecking, we compared a fixed-interval (FI) schedule in which reinforcement follows the first peck after the interval has elapsed and a differential-reinforcement-of-other behavior (DRO) schedule which requires pigeons abstain from pecking for a similar interval. The delay …


The Imprint Of Childhood Abuse On Trauma-Related Shame In Adulthood, Joan A. Reid Jan 2018

The Imprint Of Childhood Abuse On Trauma-Related Shame In Adulthood, Joan A. Reid

Dignity: A Journal of Analysis of Exploitation and Violence

Research has consistently linked residual trauma-related shame among child sexual abuse (CSA) survivors to sexual revictimization, health risk behaviors, and poorer response to mental health treatment. However, questions remain regarding the imprint of childhood maltreatment on trauma-related shame including which CSA characteristics or types of childhood maltreatment contribute to residual shame in adulthood. Using data drawn from a prospective study of 174 primarily African American women with histories of CSA and a matched comparison group, this study explores whether specific characteristics of CSA (familial CSA, CSA with penetration, force used by CSA perpetrator), repeat sexual victimization in adolescence, childhood physical …
