Subliminal priming and effects of hand dominance

In the masked priming paradigm, motor responses to targets are influenced by previously presented subliminal primes, and are guided by facilitatory and inhibitory mechanisms that depend on prime-target compatibility/duration. In this study, we evaluate subliminal-driven priming in right- and left-handers during unimanual as well as bimanual tasks. The data from the unimanual tasks confirmed that prime-target compatibility affects performance as a function of prime-target duration. In a bimanual setting, the preferred hand benefitted from facilitation in both handedness groups whereas the non-preferred hand showed a positive priming effect only in left-handers. This denotes that left-handers are more susceptible to response activation of either hand. In addition, inhibitory priming had a stronger effect on the non-preferred than preferred hand, independent of handedness group. Overall, the findings suggest that subliminal-driven mechanisms that assist adaptive motor behavior are sensitive not only to extrinsic (task-related) factors such as prime-target compatibility but also to intrinsic (performer-related) factors such as hand dominance. The data further provide support for handedness-specific effects in motor functions and underline a significant role of hand dominance in the control of bimanual actions.     

The perceptual span during foveally-demanding visual target localization

Foveally-induced processing load deteriorates target localization performance in vision-guided tasks. Here, participants searched for a target embedded among coded distractors. High processing load was effected by instructing some participants to use the coded distractors to guide their search for the target. Other participants (in the low processing load condition) were not apprised of the code. The experiment examined whether increased processing load alters the span of effective processing (i.e. perceptual span) by (a) reducing its size, (b) altering its shape, or (c) reducing its size and altering its shape. The results demonstrated a reduction in the size of the perceptual span, with no significant change to its shape. It is argued that when distractors are processed beyond simply rejecting them as non targets, the perceptual span shrinks with increasing processing load. The findings are discussed in contrast to a general interference theory that predicts a change in vision-guided performance without a shrinking of the perceptual span.     

Meehl's "crud" factor, subjective wellbeing, and religiosity: a critique'

Researchers in the area of subjective wellbeing are now building on a body of research that spans more than three decades and includes many thousands of articles. It is time to move from exploratory studies to those based on accumulated psychometric understanding and theory. Two aspects of the article by Abdel-Khalek (2011) warrant attention from this perspective: the choice of scale and the issue of shared variance.     

The Impact of Neighborhood Factors on the Well-Being of Survivors of Intimate Partner Violence Over Time

Intimate partner violence (IPV) is a pervasive social problem impacting the psychological well-being of millions of US women annually. The extant literature draws our attention to the devastating mental health effects of IPV, but largely overlooks how ecological factors may further explain survivors' well-being. This study examined how neighborhood disadvantage may contribute to survivors' compromised well-being, in addition to the abuse women experienced. Neighborhood disorder and fear of victimization significantly impacted survivors' well-being, over and above abuse. Although between-women effects of neighborhood disorder and fear were unrelated to change in women's depression or quality of life (QOL), significant within-woman effects were detected. Change in neighborhood disorder was negatively associated with change in QOL, and this relationship was fully mediated by fear. While no direct relationship between change in neighborhood disorder and depression was detected, an indirect effect through survivors' fear was revealed. Implications for future research and practice are discussed.     

A Demonstration of Set-Points for Subjective Wellbeing

This paper presents evidence for the existence of ‘set-points’ for subjective wellbeing. Our results derive from a 10-year longitudinal study in which subjective wellbeing has been measured using a single question of general life satisfaction. The process of data analysis is driven by logic based on the theory of subjective wellbeing homeostasis. This analysis involves the iterative elimination of raw data, from 7,356 individual respondents, based on confidence limits. All results are projected onto a 0–100 point scale. We demonstrate evidence for the existence of set-points lying between 71 and 90 points, with an average set-point-range of 18–20 points for each person. The implications and limitations of these findings are discussed.     

The eternal yearning

Parker Palmer defines spirituality as ‘the eternal yearning to be connected with something larger than our own egos’ (2003, 121). This yearning is an innate human need that transcends age, culture, ethnicity and belief. Despite deficit assumptions about young people, they are drawn to this need to surmount the ego and contribute to something larger than their own wants and needs. Two counter stories of young people involved in social activism outline how this is achieved. These are stories of contribution, compassion, empathy and understanding. Implications for schools are outlined including the range of learning that social activism inspires.     

What are you dieting for? The role of lay theories in dieters' goal setting

Through a qualitative study of a sample of Weight Watchers dieters, this research provides insight about the relationship between goal setting and lay theories—people's basic assumptions about the malleability of their personal attributes. We find that dieters set very different types of superordinate and subordinate goals depending on the lay theory (entity vs. incremental) they hold. Dieters who hold entity theory, which underscores immutability of abilities, set superordinate goals focused on avoiding negative social evaluations. These dieters also seem to set subordinate goals that minimize effort in diet, physical activity, and the use of group meetings necessary for weight loss. Among dieters holding incremental theory, which emphasizes malleability of abilities through learning, weight loss is guided by superordinate goals that promote change in the self. Incremental‐theory dieters also set subordinate goals that encourage rather than limit revamping lifestyle. These findings offer contributions to lay theories and goal setting in consumer research as well as implications for developing more successful weight‐loss practices.

Purity matters more than harm in moral judgments of suicide: Response to Gray (2014)

Many people judge suicide to be immoral. We have found evidence that these moral judgments are primarily predicted by people’s belief that suicide taints the soul and by independent concerns about purity. This finding is inconsistent with accounts that define morality as fundamentally based upon harm considerations. In this commentary, we respond to a critique of our finding, and we provide further support for our original conclusions. Even when applying new exclusion criteria to our data, an examination of effect sizes demonstrates that concerns about purity robustly and meaningfully explain variance in moral judgments of suicide. While harm concerns sometimes predict moral judgments of suicide alongside purity concerns, they reliably explain a much smaller proportion of the variance than do purity concerns. Therefore, data from six studies continue to suggest that the relevance of harm concerns for moral judgments of suicide is substantially overshadowed by the contribution of purity concerns.     

Examiner error in curriculum-based measurement of oral reading

Although curriculum based measures of oral reading (CBM-R) have strong technical adequacy, there is still a reason to believe that student performance may be influenced by factors of the testing situation, such as errors examiners make in administering and scoring the test. This study examined the construct-irrelevant variance introduced by examiners using a cross-classified multilevel model. We sought to determine the extent of variance in student CBM-R scores attributable to examiners and, if present, the extent to which it was moderated by students' grade level and English learner (EL) status. Fit indices indicated that a cross-classified random effects model (CCREM) best fits the data with measures nested within students, students nested within schools, and examiners crossing schools. Intraclass correlations of the CCREM revealed that roughly 16% of the variance in student CBM-R scores was associated between examiners. The remaining variance was associated with the measurement level, 3.59%; between students, 75.23%; and between schools, 5.21%. Results were moderated by grade level but not by EL status. The discussion addresses the implications of this error for low-stakes and high-stakes decisions about students, teacher evaluation systems, and hypothesis testing in reading intervention research.
