Improved Advising Ratings in an Undergraduate Psychology Program
During the late 1990s, the psychology department of Indiana University-Purdue University Indianapolis made investments in its undergraduate advising program in terms of additional professional personnel, a new orientation course, an experimental intrusive advising track, innovative peer activities, and expanded physical facilities. Against this backdrop of innovations, from 1995 to 2001 an exit survey of graduating seniors (N=311) showed improved…
Relinquish the Dog
Content analysis of selected films (Beethoven, K-9, Turner & Hooch) and a TV show (The Simpsons) revealed frequent instances of undesirable acts by dog characters including damaging, disobedience, soiling, and stealing. One reaction of human characters was frequent scolding. More seriously, all the dogs were explicitly put at risk for relinquishment (surrender). Even so, no dog was permanently relinquished. In two cases, animals eventually redeem…
Good Dog
Lay theories or assumptions about nonhuman animal mentality undoubtedly influence relations between people and companion animals. In two experiments respondents gave their impressions of the mental and motivational bases of companion animal social behavior through measures of causal attribution. When gauged against the matched actions of a boy, as in the first experiment, respondents attributed a dog's playing (good behavior) to internal, disposi…
Pets' Roles in Parents' Bereavement
A sample of 43 mothers and 21 fathers completed a retrospective survey concerning a pet's involvement in adaptation to a child's death. Measures included degree of attachment to the pet, and perceptions of the pet's helpfulness and roles in the process of grief resolution. Most parents (75%) indicated that their pet was helpful. Positive pet roles—a distraction, a comfort, a confidant—were positively correlated with degree of attachment to pet. N…
Age Preferences in Personal Advertisements
Previous interpretations of human age preferences in mates posited two sex-linked `life history strategies' said to involve the parental investment potential of the other as revealed by that other's age. In contrast with a dual strategy, our study of 722 heterosexual personal advertisements written by persons aged 20 to 59 found overall patterns of correlations (r.81 to .95) between own and stipulated ages that were common to both men and women. …
Dog Bites Boy
Separate samples of undergraduates read matched stories about a dog or a boy actor biting a child; others read about a dog or a boy playing with a child. Rating scales were used to obtain evaluations of these outcomes, and estimates of an actor's intent, volition, and excuse for its behavior. In addition, blameworthiness and impressions of actors' felt shame were assessed for biting; as was praiseworthiness for playing. Clear evidence for more le…
Differences and Similarities in Humans' Perceptions of the Thinking and Feeling of a Dog and a Boy
College students' perceptions of companion dog mentality were systematically compared with perceptions of human child mentality. Independent groups of respondents rated capacities of a dog or a boy on 12 categories of thinking and 30 items of remorseful feelings for misbehavior. The boy received superior ratings for so-called "complex" (but not "simple") thinking categories and "upper level" (but not "lower level") remorse items. Even so, there w…
Editors' Overview
Labels and the Treatment of Animals
The proposition that sheer labels or categories are important in people's reactions to the treatment of animals was supported by evidence from two sources. First, print archives showed that in the real world animals with a great deal in common such as (a) dolphins and tuna in the same nets; (b) cats and dogs, and pigs and goats in the same laboratories; and (c) native and feral species in the same parks are viewed or treated quite differently by …

Formation of leap orders in pairs of male domestic chickens
There is disagreement concerning the role or importance of social leaping, compared with pecks and threats, in the dominance relations of fowl. As an approach to this issue, the current paper reports two experiments that used aggression-inducing isolation-rearing conditions of either 8 days or 8 weeks. In 5-min tests in pairs after isolation it was found that leaping was the key aggressive response in conflicts between 14- to 15-week-old roosters…
Components of aggression in chickens and conceptualizations of aggression in general
A refined analysis of the peck order in chickens was offered as a test of the notion that for this species, different responses such as leaping and various types of pecking need not be interchangeable indexes of aggression. Indeed, tests showed that particular response types of the birds were differentially mediated by organismic or environmental factors. In large cages pecking at the body was most frequent by birds that had a home-cage advantage…
Mediating factors in chick social pecking
Two experiments examined the influence of periods of social isolation on rates of intersubject pecking in pairs of domestic chicks. Of central interest was the effect of an imprinting condition wherein single birds were reared with either a red or green Styrofoam object. In the first experiment, imprinted subjects were given social pecking tests in the absence of the imprinting object, while in the second study the tests for social pecking were c…
Mediating factors in chick social pecking
Unfamiliarity with movement may lead isolated chicks to respond aggressively when tested with live, moving conspecifics. This hypothesis was tested by comparing the number and locus of pecks by isolated chicks to a stationary or moving model of a chick, and to a live chick. In a second test of the hypothesis chicks that viewed a moving object during isolation and chicks isolated without movement were tested with a live con-specific and their numb…

Isolation-induced social pecking in domestic chicks
Aspects of the social pecking of domestic chicks in a free response situation were examined in a series of experiments. It was proposed that a dual pattern of responses involving (a) a preponderance of pecks at the head of a conspecific, and (b) heightened emotionality (as indicated by the emission of distress calls) might be taken to reflect an aggressive tendency, and evidence was reviewed that showed that a brief period of isolation was a suff…

Social factors in the facilitation of feeding in chickens
Two experiments investigated the generality of socially enhanced consummatory behavior in chickens and the conditions that influence such enhancement. The first experiment placed two consummatory responses (pecking and drinking) in competition. The design of the experiment contrasted three common interpretations of social facilitation of feeding in chickens: (a) the imitation of specific responses of another bird, (b) the arousing effect of anoth…

The Rating of Materials Found in the Mailbox
Several laboratory studies by Zajonc and his colleagues have shown that the mere repeated exposure of certain ambiguous forms or innocuous nonsense words (e.g., NANSOMA, IKTITAF, AFWORBU, etc.) serves to enhance the observer's attitude toward them. The subjects in the experiments were asked merely to pay attention to the stimuli as they appeared briefly and singly on cards or on a screen. Some stimuli were shown twenty-five times while others wer…
