Evolution and Personality: What Should a Comprehensive Theory Address and How?

Personality is arguably the most integrative area of psychology; yet, it is an area about which evolutionary psychologists have had comparatively little to say. This is unfortunate because evolutionary theory holds great potential as a framework that can link together the disparate aspects that make up a person. We suggest that progress in evolutionary personality psychology will be helped by clarification of precisely what an evolutionary theory of personality would need to address. To this end, we first describe and assess some extant contributions by theorists attempting to understand personality from an evolutionary perspective. Next, we endorse a working definition of what personality entails and outline three types of personality differences – character traits, goals/motives, and selves/identities – that any comprehensive evolutionary theory of personality should address. Finally, we suggest an approach forward, one where evolved species‐typical motives orient people toward adaptive ends and result in the differentiation of individuals’ unique selves.     

Imagination and immortality: thinking of me

Recent work in developmental psychology indicates that children naturally think that psychological states continue after death. One important candidate explanation for why this belief is natural appeals to the idea that we believe in immortality because we can’t imagine our own nonexistence. This paper explores this old idea. To begin, I present a qualified statement of the thesis that we can’t imagine our own nonexistence. I argue that the most prominent explanation for this obstacle, Freud’s, is problematic. I go on to describe some central features of contemporary cognitive accounts of the imagination, and I argue that these accounts provide an independently motivated explanation for the imaginative obstacle. While the imaginative obstacle does not dictate a belief in immortality, it does, I maintain, facilitate such a belief.     

Octopuses (Octopus bimaculoides) and cuttlefishes (Sepia pharaonis, S. officinalis) can conditionally discriminate

In complex navigation using landmarks, an animal must discriminate between potential cues and show context (condition) sensitivity. Such conditional discrimination is considered a form of complex learning and has been associated primarily with vertebrates. We tested the hypothesis that octopuses and cuttlefish are capable of conditional discrimination. Subjects were trained in two maze configurations (the conditions) in which they were required to select one of two particular escape routes within each maze (the discrimination). Conditional discrimination could be demonstrated by selecting the correct escape route in each maze. Six of ten mud-flat octopuses (Octopus bimaculoides), 6 of 13 pharaoh cuttlefish (Sepia pharaonis), and one of four common cuttlefish (S. officinalis) demonstrated conditional discrimination by successfully solving both mazes. These experiments demonstrate that cephalopods are capable of conditional discrimination and extend the limits of invertebrate complex learning.     

Selling Sex to Radio Program Directors: A Content Analysis of Radio & Records Magazine

This study was designed to examine whether radio format and musical artists' gender predict sexual content in trade advertisements geared toward radio program directors. Advertisements were coded from one of the leading music trade magazines, Radio & Records magazine, between 2002 and 2003. Results indicated that overall women artists used sexual content in trade advertisements more often and to a greater degree than did men. In some cases, advertisements in radio formats with younger demographic markets, such as pop or hip-hop, also used higher levels of sexual content. It is concluded that the organizational context of the commercial music industry helps to perpetuate status differences between women and men artists, which may then bring about a cognitive bias in the field that promotes women artists' over reliance on using sexual content in trade advertisements.     

Merton as Harvard sociologist: Engagement,thematic continuities,and institutional linkages

In this paper I explore the significance of the initial decade of Robert K. Merton's graduate and professional career, from 1931, when he entered the new doctoral program in sociology at Harvard, until 1939, when he joined the Department of Sociology at Tulane University as an associate professor and acting chairperson. Drawing on archival sources, as well as the professional literature, I examine how Merton engaged the exceptionally rich, interdisciplinary context of Harvard in the 1930s, including both interpersonal networks and diverse intellectual perspectives. In particular, I identify connections between Merton's early writing, “oral publications” and teaching, and three locally developed and dominant paradigms of sociology. Following an assessment of the influence of Merton's works published from 1934 to 1939, I trace continuities between Merton's achievements at Harvard and his subsequent teaching and research at Tulane and Columbia. I conclude that a fuller appreciation of Merton's “less noticed” decade in Cambridge is indispensable for understanding his overall career, and that it clarifies linkages across sociological work at three universities in the mid‐twentieth century. © 2010 Wiley Periodicals, Inc.     

Detectability gradients as a function of target location

We examined the ability to detect a specified visual pattern (a target) in a randomly selected location when it was briefly presented with 11 other spatially distributed nontarget patterns and also when it was presented by itself for the same duration (50 msec) on a background of visual noise. Two experiments were designed to measure target detectability as a function of its location in the visual field where all possible target locations were equidistant from the fovea. A right visual field detection superiority was obtained in both experiments. In addition, highly significant detectability differences were observed within the right and left visual fields in both experiments. The origin of these detectability differences are interpreted in terms of parallel and serial processing mechanisms.
