The personality traits of liked people

There is surprisingly little understanding of how personality traits are associated with being generally liked by others after adolescence (Ozer & Benet-Martinez, 2006). We examined the relationship between self-reported personality traits and being generally liked in young adulthood in Greek organizations and freshman dormitories. We found a high level of consistency in which traits were associated with being liked. We examined the relationship between liked and socially desirable traits, using a recent theory on agency and communion (Wojciszke, Abele, & Baryla, 2009). Results help to create a personality profile of the person who is more liked by others, especially pointing to the importance of communal characteristics that are associated with behavior benefiting others.     

How to use the diffusion model: Parameter recovery of three methods: EZ, fast-dm, and DMAT

Parameter recovery of three different implementations of the Ratcliff diffusion model was investigated: the EZ model (Wagenmakers, van der Maas, & Grasman, 2007), fast-dm (Voss & Voss, 2007), and DMAT (Vandekerckhove & Tuerlinckx, 2007). Their capacity to recover both the mean structure and individual differences in parameter values was explored. The three methods were applied to simulated data generated by the diffusion model, by the leaky, competing accumulator (LCA) model (Usher & McClelland, 2001) and by the linear ballistic accumulator (LBA) model (Brown & Heathcote, 2008). Results show that EZ and DMAT are better capable than fast-dm in recovering experimental effects on parameters. EZ was best in recovering individual differences in parameter values. When data were generated by the LCA model, the diffusion model estimates obtained with all three methods correlated well with corresponding LCA model parameters. No such one-on-one correspondence could be established between parameters of the LBA model and the diffusion model.     

Indian mate preferences: Continuity,sex differences,and cultural change across a quarter of a century

Expressed mate preferences provide unique windows into evolved mating psychology. The current study used two research instruments—one ranking and one rating procedure—to examine mate preferences in India. We compared modern Indians (n = 536) with a more modest Indian sample studied a quarter of a century earlier (n = 105) to test the hypothesis that sex-specific mate preferences—as hypothesized by parental investment theory—would persist during this time period. Mate preferences for mutual attraction and love remained important and invariant over time, despite India’s history of arranged marriages. Sex differences in mate preferences for cues to fertility (youth, physical attractiveness) and resources (good financial prospects, social status) remained relatively invariant over time. Several changes in mate preferences emerged, including a greater preference for mates who are “creative and artistic,” “ambitious and industrious,” and “a good cook and housekeeper” for both sexes. Despite cultural changes in India over the past 25 years, evolved mate preferences have persisted during this time period. Discussion highlights limitations of this research.     

An integrated perspective on the relation between response speed and intelligence

Research in the field of mental chronometry and individual differences has revealed several robust regularities (Jensen, 2006). These include right-skewed response time (RT) distributions, the worst performance rule, correlations with general intelligence (g) that are more pronounced for RT standard deviations (RTSD) than they are for RT means (RTm), an almost perfect linear relation between individual differences in RTSD and RTm, linear Brinley plots, and stronger correlations between g and inspection time (IT) than between g and RTm. Here we show how all these regularities are manifestations of a single underlying relationship, when viewed through the lens of Ratcliff’s diffusion model ( [Ratcliff, 1978] and [Ratcliff et al., 2008] ). The single underlying relationship is between individual differences in general intelligence and individual differences in “drift rate”, which is just the speed of information processing in Ratcliff’s model. We also test and confirm a strong prediction of the diffusion model, namely that the worst performance rule generalizes to phenomena outside of the field of intelligence. Our approach provides an integrative perspective on intelligence findings.     

Sensation seeking among high- and low-risk sports participants

Investigated were the sensation seeking tendencies of a diverse sample of 166 athletes. The main aim of the study was to assess empirical support for Zuckermans (1994)Impulsive-Sensation-Seeking (ImpSS) theory and to replicate and extend previous research findings in this area using high- and low-risk sport participants. The Sensation Seeking Scale-V (Zuckerman et al., 1978) and the Impulsiveness Scale of the Impulsiveness-Venturesome-Empathy Scale (Eysenck and Eysenck, 1978), were administered to both male and female athletes currently engaged in one of eight sport disciplines: Hang-gliding, mountaineering, sky-diving, automobile racing, swimming, marathon running, aerobics or golf. Results provided support for the main thrust of Zuckermans ImpSS theory (a) that sensation seeking is integrated within a broader trait called Impulsive-Sensation Seeking; and (b) that total sensation seeking differentiated between high- and low-risk sport participants. On the other hand, these participants did not differ on the impulsiveness dimension. These and other findings are integrated with respect to Zuckermans (1994)Impulsive-Sensation Seeking model. Limitations of the present study and suggestions for future research are also discussed.     

Phasic auditory alerting improves visual conscious perception

Attention is often conceived as a gateway to consciousness (Posner, 1994). Although endogenous spatial attention may be independent of conscious perception (CP) (Koch Tsuchiya, 2007), exogenous spatial orienting seems instead to be an important modulator of CP ( [Chica et al., 2010] and Chica, Lasaponara, et al., 2011). Here, we investigate the role of auditory alerting in CP in normal observers. We used a behavioral task in which phasic alerting tones were presented either at unpredictable or at predictable time intervals prior to the occurrence of a near-threshold visual target. We find, for the first time in neurologically intact observers, that phasic alertness increases CP, both objectively and subjectively. This result is consistent with evidence showing that phasic alerting can ameliorate the spatial bias exhibited by visual neglect patients (Robertson, Mattingley, Rorden, & Driver, 1998). The alerting network may increase the activity of fronto-parietal networks involved in top-down amplification required to bring a stimulus into consciousness (Dehaene, Changeux, Naccache, Sackur, & Sergent, 2006).     

Birth order differences in normal personality traits: Perspectives from within and outside the family

The hypotheses of Sulloway (1996) regarding birth order differences in five-factor model personality traits were tested in a sample of 231 college students with the NEO Five-Factor Inventory (NEO-FFI; Costa & McCrae, 1992). Data were collected from three sources (self, peer, and parent) to systematically evaluate previous observations that birth order differences are more commonly found when ratings are obtained from family members than from observers outside the family (Ernst & Angst, 1983). Using a between-family design, students were selected only from families with two or three full biological siblings and no half-siblings, step-siblings, or adopted siblings. Firstborn (n = 103) and laterborn (n = 128) students were compared using NEO-FFI ratings by the self, by a same-sex college peer, and by a biological parent. No birth order differences were found for any of the five NEO-FFI scores using any of the three rating sources. Effect sizes (Cohen’s d) were less than .20 for all comparisons. Suggestions for new approaches to the study of birth order differences are considered, including the use of within-family designs and more contextualized personality variables.     

Target-directed visual attention is a prerequisite for action-specific perception

Witt et al. (2008) have recently shown that golfers who putt with more success perceive the hole to be bigger than golfers who putt with less success. In three experiments, we systematically examined whether this phenomenon, labelled action-specific perception, depends on directing visual attention towards the action target. In Experiment 1 we replicated previously reported action-specific effects on perception in golf putting. In 3 and 4 we directly assessed whether action-specific effects on perception in golf putting are dependent on focusing visual attention on the target. To this end, the participants performed the putting task while visual attention towards the target was either completely withheld (Experiment 2) or divided over the target and other task-relevant objects (Experiment 3). No action-specific effects were found when visual attention towards the action target was occluded or partially diverted from the target. Together, our results provide evidence to suggest that focusing visual attention on the target while performing the action is a prerequisite for the emergence of action-specific perception.     

Happy today, happy tomorrow: The (non-)effect of temporal distance on judgments of Life Satisfaction

Construal Level Theory (CLT; Trope &; Liberman, 2003) posits that everyday life predictions, evaluations, and choices are influenced by how near or distant in time the event is. However, judgments of Life Satisfaction (LS) are relatively weakly influenced by situational factors and relatively strongly influenced by personality factors. Moreover, the constructive episodic simulation hypothesis ( [Schacter and Addis, 2007] and [Schacter and Addis, 2007] ) implies that memory of past events provides details for simulations of future novel experiences. Undergraduate students (N = 127) were randomly asked for how desirable LS was and for actual judgements of LS in the near- or distant-future. The results show that LS was more desirable in the distant-future. Thus, indicating that LS is abstractly assessed and judgments of LS should therefore be influenced by temporal distance as predicted by CLT. However, no significant differences in actual LS were found between conditions. Implications for theory development are discussed.     

Evidence of construct validity for work values

Despite the importance of work values in the process of career adjustment (Dawis, 2002), little empirical research has focused on articulating the domains represented within the construct of work values and the examination of evidence of validity for the construct has been limited. Furthermore, the larger number of work values measures has made it difficult to determine the key domains that constitute the construct. The current study sought to examine multiple measures of work values to understand domains represented within the construct of work values and to establish evidence of validity for these domains. Principal Components Analysis utilizing scores on the Minnesota Importance Questionnaire (Rounds, Henley, Dawis, Lofquist, & Weiss, 1981), the revised edition of Super's Work Values Inventory (SWVI-R; Zytowski, 2006), and Manhardt's Work Values Inventory (Manhardt, 1972) found that six components best explained the data. These components reflected the importance of: the working environment, having challenging work, opportunities for status and income, autonomy, organizational support, and relationships. Implications for research and practice are discussed.     

Stressful demands or helpful guidance? The role of display rules in Indian call centers

This paper utilizes conservation of resources (COR) theory and two of Hofstede's (1980) dimensions of culture (individualism and power distance) to examine the impact of display rules on job satisfaction and performance in an Indian call center sample. Contrary to findings in an American sample (Wilk & Moynihan, 2005), we proposed that due to cultural differences as well as differences in the nature of the job among representatives in an Indian call center, supervisory focus on display rules would reduce emotional exhaustion, and in turn, have positive consequences for employee performance and job satisfaction. Using multi-source data in a sample of 137 Indian call center representatives, results confirmed the hypothesized mediating effects of emotional exhaustion on performance and job satisfaction. Implications of these results for future cross-cultural research are presented.     

Proof theory and mathematical meaning of paraconsistent C-systems

A proof-theoretic analysis and new arithmetical semantics are proposed for some paraconsistent C-systems, which are a relevant sub-class of Logics of Formal Inconsistency (LFIs) introduced by W.A. Carnielli et al. (2002, 2005) [8] and [9]. The sequent versions BC, CI, CIL of the systems bC, Ci, Cil presented in Carnielli et al. (2002, 2005) [8] and [9] are introduced and examined. BC, CI, CIL admit the cut-elimination property and, in general, a weakened sub-formula property. Moreover, a formal notion of constructive paraconsistent system is given, and the constructivity of CI is proven. Further possible developments of proof theory and provability logic of CI-based arithmetical systems are sketched, and a possible weakened Hilbert?s program is discussed. As to the semantical aspects, arithmetical semantics interprets C-system formulas into Provability Logic sentences of classical Arithmetic PA (Artemov and Beklemishev (2004) [2], Japaridze and de Jongh (1998) [19], Gentilini (1999) [15], Smorynski (1991) [22]): thus, it links the notion of truth to the notion of provability inside a classical environment. It makes true infinitely many contradictions B∧¬B and falsifies many arbitrarily complex instances of non-contradiction principle ¬(A∧¬A). Moreover, arithmetical models falsify both classical logic LK and intuitionistic logic LJ, so that a kind of metalogical completeness property of LFI-paraconsistent logic w.r.t. arithmetical semantics is proven. As a work in progress, the possibility to interpret CI-based paraconsistent Arithmetic PACI into Provability Logic of classical Arithmetic PA is discussed, showing the role that PACIarithmetical models could have in establishing new meta-mathematical properties, e.g. in breaking classical equivalences between consistency statements and reflection principles.     

Schémas cognitifs, croyances addictives et défenses dans la consommation et l’addiction au cannabis de jeunes adultes

Theoretical background

Integrating the cognitive approaches based on the model of Beck et al. (1993) information treatment, the Young (1994) model of maladapted schemas, the integrative approach of Plutchik (1995) and the clinical approach based on defense mechanisms (Bond, 1995), this study aimed at investigating: (a) the role of the hyperactivated maladapted schemas, (b) the addictive beliefs, (c) the suractivation of the conscious derives of defensive mechanisms and (d) the relationships between these cognitive and defensive variables, in young people's cannabis intensity addiction.

Method

Forty-four young adults, 25 females and 19 males, have completed a self-reported questionnaire estimating: (a) the intensity of cannabis addiction (Décamps et al., 2008), (b) the Rusinek (2006) adaptation of Young's maladapted schemas and (c) the questionnaire of addictive beliefs of Tison and Hautekeete (1998) and the defensive styles questionnaire of Bond et al. (1983) and Bond (1995). Non-parametric statistical analysis has been conducted on three subject's groups (“non-users”, “users non addicted”, “users-addicted”) to test the implications and the links between hypothesized psychological factors (e.g., schemas, beliefs and defences) in cannabis use intensity.

Results and discussion

The intensity of cannabis addiction is correlated significantly with: (a) an hyperactivation of three maladapted schemas: inadequate autocontrol, dependence and fear of lose the control, (b) a hyperactivation of permissive, anticipatory and relief oriented beliefs and (c) a higher activation of the defence “sublimation” and a lower activation of the “displacement”. “sublimation” is correlated with the global activation of 13 schemas that are correlated with the positive relief-oriented beliefs, which are correlated with the “displacement” defence, which is correlated with the anticipatory beliefs. The results showed that the permissive beliefs have the power to differentiate the “non-consumption”, the “consumption without addiction” and “the addiction” to cannabis. Our interpretation displays that greater attention to the dysfunctional beliefs will be required in future researches and should be essential targets in cognitive therapy of this substance use disorder.     

An association between understanding cardinality and analog magnitude representations in preschoolers

The preschool years are a time of great advances in children’s numerical thinking, most notably as they master verbal counting. The present research assessed the relation between analog magnitude representations and cardinal number knowledge in preschool-aged children to ask two questions: (1) Is there a relationship between acuity in the analog magnitude system and cardinality proficiency? (2) Can evidence of the analog magnitude system be found within mappings of number words children have not successfully mastered? To address the first question, Study 1 asked three- to five-year-old children to discriminate side-by-side dot arrays with varying differences in numerical ratio, as well as to complete an assessment of cardinality. Consistent with the analog magnitude system, children became less accurate at discriminating dot arrays as the ratio between the two numbers approached one. Further, contrary to prior work with preschoolers, a significant correlation was found between cardinal number knowledge and non-symbolic numerical discrimination. Study 2 aimed to look for evidence of the analog magnitude system in mappings to the words in preschoolers’ verbal counting list. Based on a modified give-a-number task ( [Wynn, 1990] and [Wynn, 1992] ), three- to five-year-old children were asked to give quantities between 1 and 10 as many times as possible in order to assess analog magnitude variability within their developing cardinality understanding. In this task, even children who have not yet induced the cardinality principle showed signs of analog representations in their understanding of the verbal count list. Implications for the contribution of analog magnitude representations towards mastery of the verbal count list are discussed in light of the present work.     

The negative self-portrayal scale: development, validation, and application to social anxiety

The Negative Self-Portrayal Scale (NSPS) is a new questionnaire designed to assess the extent to which individuals are concerned that specific self-attributes they view as being deficient will be exposed to scrutiny and evaluation by critical others in social situations. These concerns have been proposed to drive symptoms of social anxiety and account for individual differences in social fears and avoidance behaviors (Moscovitch, 2009). Here, we introduce the NSPS and examine its factor structure and psychometric properties across two large samples of North American undergraduate students with normally distributed symptoms of social anxiety. Exploratory and confirmatory factor analyses supported a 3-factor solution representing concerns about (a) social competence; (b) physical appearance; and (c) signs of anxiety. The NSPS was found to have good internal consistency and test-retest reliability, strong convergent validity, and adequate discriminant validity. In addition, NSPS total scores accounted for a significant proportion of unique variance in self-concealment (i.e., safety) behaviors over and above established symptom measures of social interaction anxiety, social performance anxiety, and depression. Results are discussed in relation to theoretical models of social anxiety and the potential utility of the NSPS for both clinical research and practice.     

The impact of feedback frequency on learning and task performance: Challenging the “more is better” assumption

Previous research on feedback frequency suggests that more frequent feedback improves learning and task performance (Salmoni, Schmidt, & Walter, 1984). Drawing from resource allocation theory (Kanfer & Ackerman, 1989), we challenge the “more is better” assumption and propose that frequent feedback can overwhelm an individual’s cognitive resource capacity, thus reducing task effort and producing an inverted-U relationship with learning and performance over time. We then propose that positive and negative affective states will moderate the inverted-U relationship between feedback frequency and task performance. We test these propositions in an experimental study where the frequency of task feedback is manipulated. Results show that feedback frequency exhibits an inverted-U relationship with task performance, and this relationship is mediated by task effort. This curvilinear relationship is then moderated by individual’s positive affective state.     

How information guides movement: intercepting curved free kicks in soccer

Previous studies have shown that balls subjected to spin induce large errors in perceptual judgments ( [Craig et al., 2006] and [Craig et al., 2009] ) due to the additional accelerative force that causes the ball’s flight path to deviate from a standard parabolic trajectory. A recent review however, has suggested that the findings from such experiments may be imprecise due to the decoupling of perception and action and the reliance on the ventral system (van der Kamp, Rivas, van Doorn, & Savelsbergh, 2008). The aim of this study was to present the same curved free kick trajectory simulations from the perception only studies ( [Craig et al., 2006] and [Craig et al., 2009] ) but this time allow participants to move to intercept the ball. By using immersive, interactive virtual reality technology participants were asked to control the movement of a virtual effector presented in a virtual soccer stadium so that it would make contact with a virtual soccer ball as it crossed the goal-line. As in the perception only studies the direction of spin had a significant effect on the participants’ responses with significantly fewer balls being intercepted in the spin conditions when compared to no-spin conditions. A significantly higher percentage of movement reversals for the spin conditions served to highlight the link between information specifying ball heading direction and subsequent movement. The coherence of the findings for both the perception and perception/action study are discussed in light of the dual systems model for visual processing.     

The whole is indeed more than the sum of its parts: perceptual averaging in the absence of individual item representation

We tested Ariely's (2001) proposal that the visual system represents the overall statistical properties of sets of objects against alternative accounts of rapid averaging involving sub-sampling strategies. In four experiments, observers could rapidly extract the mean size of a set of circles presented in an RSVP sequence, but could not reliably identify individual members. Experiment 1 contrasted performance on a member identification task with performance on a mean judgment task, and showed that the tasks could be dissociated based on whether the test probe was presented before or after the sequence, suggesting that member identification and mean judgment are subserved by different mechanisms. In Experiment 2, we confirmed that when given a choice between a probe corresponding to the mean size of the set and a foil corresponding to the mean of the smallest and largest items only, the former is preferred to the latter, even when observers are explicitly instructed to average only the smallest and largest items. Experiment 3 showed that a test item corresponding to the mean size of the set could be reliably discriminated from a foil but the largest item in the set, differing by an equivalent amount, could not. In Experiment 4, observers rejected test items dissimilar to the mean size of the set in a member identification task, favoring test items that corresponded to the mean of the set over items that were actually shown. These findings suggest that mean representation is accomplished without explicitly encoding individual items.     

Motivational climate interventions in physical education: A meta-analysis

Objective

The purpose of this study was to synthesize findings from motivational climate interventions employing [Ames, 1992a] and [Ames, 1992b] and [Epstein, 1988] and [Epstein, 1989] TARGET framework within school-based physical education contexts.

Design

The present study employed a quantitative research synthesis design. Meta-analysis uses empirical studies to summarize past research by drawing overall conclusions from separate investigations. This research design highlights important and unsolved issues related to motivational climate interventions within physical education.

Methods

Standard meta-analytic procedures incorporating inclusion and exclusion criteria, literature search, coding procedures, and statistical methods were used to identify and synthesize 22 studies with 24 independent samples. Cohen’s (1988) criteria for effect sizes were used to interpret and evaluate results.

Results

There was an overall small positive treatment effect (g = 0.103) for groups exposed to mastery motivational climates. Outcome analyses identified the most consistent and largest overall treatment effects for behavioral outcomes (g = 0.39–0.49) followed by affective outcomes (g = −0.27 to 0.59) and cognitive outcomes (g = −0.25 to 0.32). Moderator analyses were directed by study heterogeneity and identified several trends in intervention features and study features with the most substantial trend for participant features as elementary students had the largest overall treatment effect (g = 0.41).

Conclusions

Outcome and moderator analyses identified several trends in methodological features, participant features, and study features that should be addressed in future physical education motivational climate interventions.
