Pigeons discriminate continuous versus discontinuous line segments

Three experiments examined various facets of the perception of continuous and discontinuous line segments in pigeons. Pigeons were presented with 2 straight lines that were interrupted by a gap. In some instances, the lines were the same angle and were positioned so that they appeared (to human observers) to form a continuous line. In other instances, the lines were different angles or the same angle but spatially misaligned. The birds were trained to classify each stimulus as continuous or discontinuous using a go/no-go procedure. A series of tests followed in which the birds received novel discontinuous displays made up of familiar line segments, continuous and discontinuous stimuli made up of novel line segments (novel straight lines or curved lines), and familiar displays in which the gap was covered with a gray square. Results from the tests indicated that 2 of the 3 pigeons had learned a continuous-discontinuous categorization and that they appeared to use the relationship between the 2 line segments in discriminating the displays.     

Personality and Intelligence in Business People: A Study of Two Personality and Two Intelligence Measures

This study examined the overlap and correlations among two well-known personality measures (NEO-PI–R; Myers-Briggs Type Indicator, MBTI) and two widely used intelligence tests (the Graduate Management Assessment (GMA), Watson-Glaser Critical Thinking Appraisal (WGCTA)). The GMA measures both fluid intelligence (Gf) and crystallized intelligence (Gc), whereas WGCTA mainly assess Gc. A total of over 3,500 participants completed the four measures in a middle management assessment event. Correlational analysis showed that Extraversion on the MBTI tended to be associated with Openness and Stability on the NEO. Intuition was associated with Openness and Introversion. Feeling types tended to be both Agreeable and Neurotic while perceiving types were high on Openness but low on Agreeableness. The NEO Big Five factor of Openness was most consistently and significantly associated with both measures of intelligence (r = .09 to r =.12). Results from the MBTI showed that Intuition and Perceiving scores were positively and significantly associated with both intelligence test scores which were intercorrelated (r = .38). Regressional analysis showed that personality traits are logically and coherently related to intelligence test scores. Implications for selection and assessment are considered.     

The Impact of Breast Cancer Genetic Risk Assessment on Intentions to Perform Cancer Surveillance Behaviors

One hundred and fifty-four women undergoing breast/ovarian cancer genetic risk assessment completed questionnaires at entry into the Cancer Genetic Service for Wales (CGSW) assessment program and following risk provision, mapping the strength of intentions to engage in a number of preventive/surveillance behaviors, including seeing specialists, breast self-examination, and involvement in screening programs, including mammography. A number of potential predictors of intentions were also assessed, including participants' mood and emotional response to receiving risk information, the perceived benefits (in terms of reassurance and early disease detection) of engaging in each preventive behavior, and the perceived desires of their family and General Practitioner. Intentions to self-examine did not change following risk provision, although strength of intentions to engage in some other preventive behaviors did lessen. Family and General Practitioners appeared to be strong social influences on behavioral intentions, as were the perceived benefits of gaining reassurance and/or early detection of disease.     

Experiences of time loss among videogame players: an empirical study.

Playing videogames is now a major leisure pursuit, yet research in the area is comparatively sparse. Previous correlational evidence suggests that subjective time loss occurs during playing videogames. This study examined experiences of time loss among a relatively large group of gamers (n = 280). Quantitative and qualitative data were collected through an online survey. Results showed that time loss occurred irrespective of gender, age, or frequency of play, but was associated with particular structural characteristics of games such as their complexity, the presence of multi-levels, missions and/or high scores, multiplayer interactions, and plot. Results also demonstrated that time loss could have both positive and negative outcomes for players. Positive aspects of time loss included helping players to relax and temporarily escape from reality. Negative aspects included the sacrificing of other things in their lives, guilty feelings about wasted time, and social conflict. It is concluded that for many gamers, losing track of time is a positive experience and is one of the main reasons for playing videogames.     

Drawing the net: internet identification, internet use, and the image of internet users.

Theory and research suggest that Internet identification may account for some of the gender divide in Internet use. Internet identification is a type of domain identification, and is inherently bound with images of those who use the Internet, a domain traditionally conceived as masculine. Combining the "draw an Internet user" test with an Internet identification scale, this study tests two hypotheses: participants drawing gender-concordant images will (i) identify with and (ii) use the Internet more than those drawing gender-discordant images. Participants were 371 students (121 males, 250 females) from three universities in the United Kingdom and Australia. The need to challenge masculinized images of the Internet is discussed.     

Male physical attractiveness in Britain and Greece: a cross-cultural study

The waist-to-chest ratio (WCR), body mass index (BMI), and waist-to-hip ratio (WHR) are the major cues to women's ratings of men's bodily attractiveness (J. T. Fan, W. Dai, F. Liu, & J. Wu, 2005; D. M. Maisey, E. L. E. Vale, P. L. Cornelissen, & M. J. Tovée, 1999; V. Swami & M. J. Tovée, 2005b). The authors examined the relative importance of each of these cues cross-culturally in Greece and Britain. Participants were 36 British and 40 Greek women who rated a set of images of real men with known WCR, BMI, and WHR. The results showed that, regardless of the cultural setting, WCR was the primary determinant of men's physical attractiveness to women, with BMI playing a minor role. However, there were also cross-cultural differences: The Greek women showed a stronger preference for a lower WCR and smaller overall body weight than did the British women. The authors considered possible explanations of these findings.     

Ocular motor indicators of executive dysfunction in fragile X and Turner syndromes

Fragile X and Turner syndromes are two X-chromosome-related disorders associated with executive function and visual spatial deficits. In the present study, we used ocular motor paradigms to examine evidence that disruption to different neurological pathways underlies these deficits. We tested 17 females with fragile X, 19 females with Turner syndrome, and 40 females with neither disorder who comprised the comparison group. Group differences emerged for both the fragile X and Turner syndrome groups, each relative to the comparison group: Females with fragile X had deficits in generating memory-guided saccades, predictive saccades, and saccades made in the overlap condition of a gap/overlap task. Females with Turner syndrome showed deficits in generating memory-guided saccades, but not during either the predictive saccade or gap/overlap task. Females with Turner syndrome, but not females with fragile X, showed deficits in visually guided saccades and anti-saccades. These findings indicate that different brain regions are affected in the two disorders, and suggest that different pathways lead to the similar cognitive phenotypes described for fragile X and Turner syndromes.     

The parser doesn't ignore intransitivity, after all

Several previous studies (B. C. Adams, C. Clifton, & D. C. Mitchell, 1998; D. C. Mitchell, 1987; R. P. G. van Gompel & M. J. Pickering, 2001) have explored the question of whether the parser initially analyzes a noun phrase that follows an intransitive verb as the verb's direct object. Three eye-tracking experiments examined this issue in more detail. Experiment 1 replicated the finding that readers experience difficulty on this noun phrase in normal reading and found that this difficulty occurs even with intransitive verbs for which a direct object is categorically prohibited. Experiment 2, however, demonstrated that this effect is not due to syntactic misanalysis but to disruption that occurs when a comma is absent at a subordinate clause/main clause boundary. Experiment 3 replicated the finding (M. J. Pickering & M. J. Traxler, 2003; M. J. Traxler & M. J. Pickering, 1996) that when a noun phrase "filler" is an implausible direct object for an optionally transitive relative clause verb, processing difficulty results; however, there was no evidence for such difficulty when the relative clause verb was strictly intransitive. Taken together, the 3 experiments undermine the support for the claim that the parser initially ignores a verb's subcategorization restrictions.
