Maturational and situational determinants of reaching at its onset

At 3 months of age, reaching behavior was measured in a group of 10 girls and 10 boys born at term. The assessments were carried out on the average 2 days after reaching onset. Reaching kinematics was measured in both supine and reclined positions. Girls reached more than boys, had straighter reaching trajectories and movements of shorter durations as well as fewer movement units. The reclined position gave rise to straighter trajectories in both girls and boys. Several anthropometric parameters were measured. Girls had less length and volume of the forearm than boys but similar upper arm volumes. There was a weak relation between kinematic and anthropometric variables.     

Schematic and situational determinants of depressed and nondepressed students' interpretation of feedback

We examined whether depressed persons' social skill deficits contribute to their negative cognitions and whether this contribution is independent of their negative schemata. Depressed (n = 60) and nondepressed (n = 60) subjects engaged in group discussions. We assessed subjects' social competence schemata with a questionnaire and subjects' actual level of social competence in the discussion through objective ratings made by codiscussants and outside observers. We found that independently of their negative schemata, depressed subjects' social skill deficits explained a significant portion of the variance in their more negative interpretation of feedback (relative to nondepressed subjects'). This suggests that real deficits in depressed persons' performance compound the effects of their negative schemata and further contribute to their negative cognitions. We also further explored findings by Dykman et al. (1989) and Lewinsohn et al. (1980).     

Integrating situational and dispositional determinants of job satisfaction: findings from three samples of professionals

Job satisfaction can be conceptualized as a function of situational conditions, personal characteristics, and interactions between both groups of variables. The authors compared the relative predictive power of these determinants in 3 samples of professionals (total N = 1,065). Perceived job characteristics (qualification possibilities, social support, stress, autonomy, participatory leadership) uniquely explained 7-22% of the variance in job satisfaction, and dispositional factors (Big Five, occupational self-efficacy, work centrality, mastery goals) uniquely explained 8-12% of the variance. Dispositional influences were partially mediated by perceived job characteristics. Interactions between situational and dispositional factors were of little significance. The authors concluded that perceived job characteristics (especially autonomy and participatory leadership) are important determinants of job satisfaction, and neuroticism is an important determinant as well. Highly educated professionals' job satisfaction also seems to be driven by qualification possibilities.     

Biographical determinants of achieved eminence: a multivariate approach to the Cox data.

Ranked eminence of creators and leaders was hypothesized to be a function of both substantive (developmental and productive) variables and methodological artifacts. Cox's sample of 301 geniuses was reexamined using multiple-regression techniques. The results indicated that ranked eminence is (a) a curvilinear inverted-U function of education for creators but a negative linear function for leaders, (b) a positive linear function of versatility for leaders only, and (c) a curvilinear U-shaped function of life span for creators but a "backwards-J" function for leaders. Although creators are more intelligent than leaders, the correlation that Cox found between intelligence and ranked eminence was shown to be an artifact of data reliability and, especially, a timewise sampling bias. It was also shown that father's status has no direct impact on ranked eminence.     

Individual differences in anger and sadness: in pursuit of active situational features and psychological processes

In the cognitive-affective personality system (CAPS) theory of Mischel and Shoda (1995, 1998), personality is conceived as a system of cognitions and affects that mediates between active situational features and behavior. Two major tasks for this approach to personality are the search for active situational features and for mediating psychological processes within a behavioral domain of interest. We report two studies to address these tasks for the domain of anger and sadness. To design these studies and to analyze the obtained data, novel extensions of our previous developed Triple Typology Model (TTM; Vansteelandt & Van Mechelen, 1998) are proposed. These extensions allow the researcher to test hypotheses concerning potentially relevant active situational features in a systematic and confirmatory way and to examine psychological processes as they occur in concrete situations.     

Individual,situational, and cultural correlates of acquiescent responding: Towards a unified conceptual framework

Acquiescence (‘yea-saying’) can seriously harm the validity of self-report questionnaire data. Towards a better understanding of why some individuals and groups acquiesce more strongly than others do, we developed a unified conceptual framework of acquiescent responding. Our framework posits that acquiescent responding is a joint function of respondent characteristics (e.g. age, education, values), situational/survey characteristics (e.g., interview privacy, respondents’ interest), and cultural characteristics (e.g., social norms, economic development). The framework posits two putative mechanisms through which these characteristics may relate to acquiescence: cognitive processing capacities and deferential communication styles. Multilevel analyses using data from 60 heterogeneous countries from the World Values Survey (N = 90,347) support our framework's proposition that acquiescence is a joint function of respondent, situational, and cultural characteristics. Acquiescence was higher among respondents who were older (over 55 years old), less educated, who valued deference (i.e., conformity and tradition), and, unexpectedly, were male. Interview privacy corresponded to lower acquiescence, but this association was small and vanished after including respondent characteristics. Unexpectedly, acquiescence was higher in interviewees who showed a stronger interest in the interview. Finally, acquiescence was considerably higher in countries with stronger social norms of deference. We discuss implications of these findings for the validity of research based on self-report data and delineate how our framework can guide future inquiries into acquiescent responding.     

Personality, motivational and situational determinants of regular and occasional use of smokeless tobacco

This study evaluated the effects of personality, motivational, and situational factors on Regular (n=191) and Occasional (n=80) users of smokeless tobacco (SLT) products. The participants completed the Eysenck Personality Questionnaire (EPQ), Spielberger’s State-Trait Personality Inventory (STPI) and Anger Expression (AX) Scale, and questionnaires designed to evaluate the reasons why SLT-Users begin, continue, and are motivated to use smokeless tobacco. Occasional Users had higher scores than Regular Users on the EPQ Extraversion scale; no other personality differences were found between these groups. Ratings of the importance of the reasons for beginning to use tobacco products were quite similar for the Regular and Occasional Users; novelty and enjoyment were ranked highest by both groups. In contrast, Regular Users rated 7 of the 10 reasons for continuing to use tobacco as significantly more important than Occasional Users; enjoyment, stimulation and management of emotions were ranked as most important by both groups. Findings that smokeless tobacco products enhanced positive affect and intellectual stimulation, and reduced anxiety and boredom were generally consistent with Eysenck’s Diathesis Stress Model.     

Trait aggressiveness and situational provocation: a test of the traits as situational sensitivities (TASS) model

In this article, the authors propose and test an interactionist model of personality functioning. The model maintains that many traits function in a threshold-like manner, such that less situational strength is needed to evoke a trait-relevant response in people who are high on the trait than in those who are low on the trait. Because of these different sensitivities, people who are high on a trait are more reactive to moderate provocation than are those who are low on a trait, but the opposite is true when strong provocation is compared to moderate provocation. Three studies are reported showing how the model can be used to understand the nature of aggression.     

Perceived Conflict and Leader Dominance: Individual and Contextual Factors Behind Preferences for Dominant Leaders

Recent research finds that political candidates and leaders with dominant, masculine physical features are more preferred under conditions of conflict than of cooperation. Importantly, however, methodological limitations of past research have hindered the identification of whether this effect reflects that voters intuitively view (1) dominant leaders as more competent in solving problems of conflict, (2) nondominant leaders as more competent in solving problems of cooperation, or (3) both. In this article, we utilize recent advances in evolutionary psychology to form precise predictions on the nature of the underlying psychology and employ an unprecedented array of data types—including highly controlled experiments, natural experiments, and behavioral measures—to investigate the validity of these predictions. Using large approximately nationally representative surveys of 2,009 Poles and Ukrainians fielded during the Crimea crisis in 2014, we find that preferences for leader dominance are exclusively driven by the intuition that dominant leaders are better able to facilitate aggressive responses during social conflict and that these preferences are regulated by contextual conditions and individual predispositions related to such responses.     

The effects of unipolar sex-role identities and situational determinants on components of fear of success

In the present study the relationship between unipolar models of sex-role identity (i.e., the degree to which a person perceives him/her self as relatively masculine and/or feminine) and situational cues (i.e., females engaged in successful activities which vary in their sex-role appropriateness) on fear of success was investigated. An alternative, objective measure of fear of success was employed which generated 16 variables thought to reflect various theoretical and empirical components of the motive to fear success. These variables dealt with personal attributes of the successful characters, reasons for their success, and possible consequences of their success. It was found that situational rather than psychological variables are of greater importance in affecting female response to female success. However, there was some support for the notion that general diffusion of sex-role identity (undifferentiated sex-role identity group) rather than high femininity may be related to avoidance of success.     

Individual and social determinants of winning bids in online auctions

• Online auctions have grown in popularity since the inception of eBay in 1995. Yet despite the phenomenal growth, little is understood about the individual and collective motivations of consumers that lead to higher bids and ultimately, higher profits. This research reframes auction theory in terms of consumer behavior theory and uses observational data to assess bidder‐generated behavior in response to seller‐generated decisions. Results suggest that an increased number of visual cues (pictures) influences bids placed early in the auction and that those early bids generate activity among other bidders, subsequently resulting in higher winning bids. In addition, our findings indicate that the starting price, as determined by the seller, also impacts the final winning bid. Research and seller implications are offered, as are future directions for research in studying this still new phenomenon.
